Author interview with Neil Middleton and Stuart Newson: Sound Identification of Terrestrial Mammals of Britain and Ireland

This groundbreaking book provides the reader with a unique and practical guide to collecting and using acoustic survey data to identify terrestrial mammals. Covering 42 species that can be found in Britain and Ireland, the text includes guidance on survey methods, analysis of sound recordings and details of appropriate software. As well as containing specific spectrogram examples for each species, the book allows the reader access to a downloadable sound library containing more than 250 recordings.

Neil Middleton is a licensed bat worker and trainer and is the owner of BatAbility Courses & Tuition, an organisation that delivers ecology-related skills development to customers throughout the UK and beyond. He has studied bats for over 25 years, with a particular focus on their acoustic behaviour (echolocation and social calls) and is the author of Social Calls of the Bats of Britain and Ireland, Is That a Bat?, and The Effective Ecologist.

Stuart Newson is a Senior Research Ecologist at the British Trust for Ornithology (BTO), where he is involved in survey design and data analysis from national citizen-science surveys. Stuart’s work on bioacoustics has included creating tools to identify European bats, bush-crickets and small mammal species from their ‘calls’. This resulted in the BTO Acoustic Pipeline, which integrates online tools for coordinating fieldworkers, processing recordings, and returning feedback.

Neil and Stuart recently took some time out of their busy schedules to answer some of our questions about their most recent book. In this Q&A we discuss the challenges involved in acoustic monitoring of mammals, the author’s hopes for the future of this area of study, and much more.

You each have a passion for acoustic monitoring – how did you come to be working together on this project?

Before we first met, Stuart was becoming interested in what else is recorded as ‘by-catch’ when you leave out a static bat detector to record bats. He had previously become interested in the sound identification of bush-crickets which are commonly recorded during bat surveys in southern Britain, and thanks to work that Neil was involved with (e.g. the first edition of the book The Social Calls of the Bats of Britain & Ireland), Stuart was becoming increasingly interested in bat social calls. At this time, he realised that small mammals are also quite commonly recorded as ‘by-catch’ during bat surveys, and was starting to appreciate that unless you had a good understanding of bat echolocation and social calls, there was scope for mis-identifying small mammals calls as being produced by bats.

When Neil started working on the book, Is That a Bat? A Guide to Non-Bat Sounds Encountered During Bat Surveys (ITAB), Stuart had already made available some online resources to help bat workers identify bush-crickets, which were able to feed into Neil’s book, and he also had some first recordings of some small mammal recordings that he was able to contribute to ITAB, which were very useful additions to the recordings that Neil had been gathering independently.

At about the same time, Stuart had met Huma Pearce, the third author on this book, and had started to work with her on an ‘edge-of-desk’ project to try and collect sound recordings for every species of small mammal in the UK. The aim was to try and collect many hundreds (ideally thousands) of sound recordings of every small mammal species in Britain and Ireland, which we wanted to build into bat classifiers to be able to assist with automatically identifying small mammals (as well as bush-crickets), when these are recorded as by-catch during bat surveys.

Working with Huma, and then Neil, to collect recordings for small mammals to feed into ITAB, and for Stuart to feed into his classifiers, we were now collecting a lot of recordings of small mammal species. After the publication of ITAB, we had learnt a lot more between us, so we wrote a more detailed guide to the sound identification of small mammals in Britain and Ireland, which was published in British Wildlife. After being approached by Pelagic Publishing, Neil was asked if he could author a book covering all terrestrial mammals in our part of the world. This was a much wider group than the one we had worked on up until that point. Neil agreed to the book idea, but only on the basis that Stuart and Huma would be involved as well. Thankfully both Stuart and Huma were ‘up for it’ and between us we managed to produce the book. I think we would all agree that if any one of us had not been involved, the job would’ve been considerably harder and taken much longer.

There currently exists a huge sound library of vocalisations of bats and cetaceans and their use in monitoring these species is now mainstream. Why do you think that this approach has not, so far, been used for other mammals such as those covered in your book?

We think that the main reason that so little has been done on the sound identification of terrestrial mammals (other than bats), is that for small mammals the call rate is quite low compared with other groups such as bats, and because the vocalisations can look like bat calls. I think until our various pieces of work, they have been largely overlooked. Until relatively recently, bat social calls had also been largely ignored by many bat workers, so there were few possibilities for noticing or identifying small mammal calls via that group. For audible mammal species, such as deer, there are alternative survey methods, such as visual surveys, and combined with this the call rate is again quite low, so without tools to help find these calls within large acoustic datasets it has been challenging to find and identify vocalisations by these species. In addition, before this book there was no resource or reference that people could use to help support the sound identification of audible mammals across the full range of species.

Added to this, we feel that the subject is difficult for many people in the non-bat mammal world to engage with and/or know where to start. Hopefully this book will open people’s eyes (and ears!) to the subject, thus meaning that more people will pay more attention to acoustic identification of these species, which will also mean that, overall, our rate of learning as a community will increase substantially as we begin to find out even more about the subject, including of course things that we didn’t appreciate at time of writing.

As well as providing the information and data required for species identification, do you think that acoustic data have the potential to tell us more about species behaviour, social interactions and population dynamics?

We think that there is huge potential for acoustic data to tell us much more about species behaviour, social interactions and population dynamics. As explored in the book, for some species we are able to relate particular call types to behaviour or status, but we still have a lot to learn for many of the species that are included in the book, in order to be able to understand in what situations particular calls are produced. By writing this book, we hope that this will inspire others to build on our work, and to accelerate an improvement in knowledge.

Which of the British terrestrial mammal species have you found the most challenging to study and why?

It is difficult to give a single answer to this one, but despite each of us having separate thoughts we would all agree on the following.

It was extremely difficult to collect or find existing sound recordings of rabbits and hares, because the call rate is extremely low. Huma (assisted by others) put lots of effort into rabbits, but sadly the results were zero. Separately Stuart tried to collect recordings of moles, by sinking microphones into the ground along mole tunnels, but he had no luck despite several weeks of effort.

Stuart would like to do more work on the sound identification of mustelids, which we feel we do not understand as much as we would like. We would all like to continue with more work on the small mammals, although we would each have different priorities in that respect. Shrews are of particular interest to us all, and Stuart in particular would definitely like to try and collect more sound recordings of Water Shrews.

Researchers have previously observed regional differences in the vocalisations of small birds recorded in various locations around Britain. Did you notice any geographic variations in the sounds produced by the mammal species you studied?

Personally, we haven’t seen much, if any, evidence of geographic variation in the recordings that we have looked at, but there could very well be regional differences. For some species it can be shown that differences occur at the individual level. This being the case, you could perhaps expect to see differences between social groups and, as such, regional and national differences too. At this point in time the amount of data we have is too small and hasn’t been collected with this in mind, and therefore we haven’t gone looking for an answer to this question ourselves.

There are currently several citizen science projects around the UK that the public can submit sightings to (such as those organised by the Mammal Society or apps such as iRecord). Is there currently anywhere that people can submit records resulting from acoustic data? Or somewhere they can submit their recordings in the hopes of building a library of sound files for each species as there is for bats?

Not that we are aware of, in the style that you have suggested by your question. However, if someone has heard (not seen) a species and they are happy that it is a diagnostic record for that species in a particular area, we would see no reason why a citizen science project would not accept the ‘sound’ as a valid record of the species being present at that location at that point in time. The key to this, however, is being confident that what was heard couldn’t be a similar noise made by something completely different – so we urge caution. It should also be remembered that in some cases sound identification may actually be more reliable than a visual record of a distant mammal, or a small mammal irrespective of how close it may be to the observer.

In a slightly different direction to your question, Stuart is best placed to talk about the use of such calls in building classifiers. His main interest in mammals has been to build a large sound library of known species recordings that can be used to build classifiers that can help identify the calls of different species automatically within recordings, with the book being secondary or a by-product of this. He believes that having such tools is essential for helping to find the calls of terrestrial mammals in large acoustic datasets, particularly for species where the call rate is low. The sound identification of all species of small mammals included in the book has been built into the ‘bat’ classifiers that comprise the BTO Acoustic Pipeline. The Acoustic Pipeline also includes specific classifiers for some audible species, including the Edible Dormouse. To the best of Stuart’s knowledge this is the first attempt from anywhere in the world to build classifiers for the sound identification of a complete assemblage of small mammals.

What are the next steps required to progress this research and what are your hopes for the future of this field of study?

There is still a lot to learn about the sound identification of mammals in Britain and Ireland, but there are some species groups on which we know we have done much less work and have less understanding than others. In particular, we think that acoustics could be useful for detecting the presence of mustelids (as we have already demonstrated for mice, rats, voles, shrews and dormice), but we would need to try and collect many hundreds (ideally thousands) of known species recordings, to be able to understand the full range of calls that a species can produce. This information could then also be used to create automated classifiers, thus enabling the possibility of efficient detection of species in this group from within large datasets.

As a longer-term ambition, Stuart is keen to work further on the wider sound identification of European mammals, and to extend the geographic and taxonomic scope of the BTO Acoustic Pipeline. Currently, he is able to identify small mammals in bat recordings from elsewhere in Europe at least to genus, by including similar closely related species from the UK in regional classifiers for other parts of Europe. However, he needs more targeted recording of known species to be carried out in order to be able to assign these identifications to species, and to be able to build classifiers that support the sound identification of mammals more widely across Europe.

Our hopes are that this book inspires others in Europe (and further afield) to work on the sound identification of mammals, and more widely to see the opportunities that understanding acoustics can offer.

Author interview with Neville Davies: The Eurasian Hoopoe

Once resident in the UK, the Eurasian Hoopoe is the most widespread of its genus and is much admired for its striking appearance and entertaining character. Containing a huge amount of astonishing and fascinating facts about these magnificent birds, this book is packed with everything you need to know about this species. It is a captivating read for beginner, intermediate or expert alike, and for anyone who has an interest in birds and the natural world.

Neville Davies is an author, wildlife columnist, book reviewer, leader of nature walks and courses, and private bird guide specialising in the birdlife of Mallorca. His previous book, Birds of Mallorca provides readers with an essential guide to the best birding sites and 340 bird species that can be found on the Balearic island of Mallorca.

The Eurasian Hoopoe, which is due for publication at the end of November, provides an in-depth look at one of the species that has fascinated Neville since childhood.

We recently chatted with him about his inspiration behind the book, his hopes for the future of this incredible species, and his plans for further writing.

What inspired you to write a book about the Eurasian Hoopoe?

As a child I would often look through the bird books I had at the time, and one species that stood out for me from the hundreds of others was the European Hoopoe (hereafter referred to as the Hoopoe). There was something magical about this strange looking bird, with its ‘punk rocker’ plume of head feathers and black and white wing markings. It looked like an iconic bird and when I read it was found on the continent and other far-away places (which I assumed I would probably never get to visit), this made it even more special – the Hoopoe would forever be out of my grasp, or so I thought. Every time I acquired a new bird book, I always found myself going straight to the page on the Hoopoe. By 1990 I had decided that I was going to visit Mallorca specifically to find them; an early guidebook I had bought listed the Hoopoe as a common resident breeder, so I felt I had a good chance of finding one.

But by the third day of my first visit to Mallorca, there was still no sign of a Hoopoe. I was beginning to think that I was never going to see one and disappointment and anxiety started to creep in. But later that third day, I saw my first ever one flying low across a field and out of sight behind a farm building. I punched the air in sheer delight, I had finally seen one for real and my excitement was overwhelming. I went in search of it and spotted it along with a second bird. And what I had thought when looking through the guidebooks as a child was right, the Hoopoe is truly a magical bird and they look as characteristic in real life as in the books – the plume of punk rocker head feathers did not disappoint.

I already owned several bird books by other authors specifically on a single bird species, and this got me thinking, why not write about the Hoopoe? Not only is the Hoopoe my favourite species in the bird world, but surely there must be enough information available to make an interesting book. I was pleased to find research papers written on the Hoopoe from all over the world – there was certainly enough information for a book. The more I looked the more I found, and I learned so much about the Hoopoe that I didn’t already know. There were also some great photographs in these papers, and I started to contact several of the authors to ask if I could use their images and some of their findings. Thankfully, they were very keen to support me, so along with my own images and information I was able to provide more in-depth information, especially around breeding and prey items, and excellent photographs.

Could you tell us about the status of the Hoopoe and the kinds of threats they face?

The European breeding population is large (890,000 pairs), and the Hoopoe is doing well across the rest of its range in Asia and Africa; it is regarded as a species of Least Concern due to its widespread population. This does not mean we should be complacent, however, as the Hoopoe still faces threats, especially from hunting. The Hoopoe is regarded as a trophy species, and their distinctive undulating flight makes it an easy target for hunters and poachers. In Lebanon, for example, they are kept in cages to be sold in local markets and are often in a dreadful condition and poorly fed. It is sickening and distressing to know that a bird as majestic as the Hoopoe (or any bird for that matter) lives out the rest of its life in a cage, unable to enjoy the freedom of flight. One organisation that is doing sterling work to protect not just the Hoopoe but all birds is the Committee Against Bird Slaughter. They conduct annual bird protection operations in Spain, Italy, Malta, Cyprus and Lebanon.

Hoopoes face other forms of predation in the wild too. Both the Eleanora’s Falcon and Sooty Falcon will target Hoopoes as they migrate across open areas of water, where they are tired and easy prey. At their nest sites they can fall prey to several predators, with the seven main culprits being the Western Whip Snake, European Asp, Eurasian Magpie, Little Owl, Red Fox, Black Rat and domestic Cats.

You mention that Hoopoes were once resident in the UK but are now passing migrants. Could the Hoopoe make a long-term return?

Hoopoes were once a resident species in the UK but are now confined to being a scarce but regular passage migrant to Britain, with most sightings occurring in the spring and autumn. On average, sightings range between 100 and 150 individuals with the bulk of UK records coming from the south coast counties, although there are records from every county in the UK. The Hoopoe has bred here sporadically since the early 19th century with at least 1–4 instances recorded in each decade since the 1830s (again mostly from the southern counties). More modern records have appeared in 1971, 1976, 1977 and 1996. In 1977, pairs fledged young in Avon, Somerset, Surrey and Sussex, which is quite remarkable. The 1996 occurrence came from the Montgomeryshire area. On average, singing males are recorded every five years or so (males sing to attract females). Could they make a long-term return to the UK? Why not. In fact, recent news from Leicestershire reports that a pair of Hoopoes have successfully bred and raised three young and been seen frequenting a private garden.

Favourable conditions can bring in arrivals in large numbers, in some years this can be as early as late February. Hoopoes can turn up anywhere, with Ireland having at least 15 records; although, the further north one goes the scarcer the records become. Visiting the south coast during spring does not guarantee a Hoopoe sighting but it is certainly when and where there is the best chance of finding one. In southern England, favoured localities include the Isles of Scilly; Porthgwarra; Land’s End and the Lizard, Cornwall; Start Point and Prawle Point, Devon; Portland, the Needles, Isle of Wight; Selsey Bill, West Sussex; Dungeness and Sandwich Bay, Kent. Favourable likely locations on the east coast include Blakeney Point in Norfolk and Spurn East in Yorkshire. In the autumn, east coast locations tend to fair better sightings wise, with a scatter of drift and reverse migrants.

What conditions would be necessary for such a return?

In spring, when high pressure leads to fine settled weather over Western Europe, some migrants returning to the Mediterranean region fly right over their intended target and end up in Britain. This is known as overshooting. Across their range, Hoopoes can be seen in a variety of habitats, including gardens, parks, towns, villages, marsh edges, open fields with vegetation and ploughed fields. They can also be found in groves of olives, almonds, grapes and other fruits where the lines of trees provide shade, allowing them to feed during the hottest parts of the day, and the diversity of vegetation and rich soil also support a good variety of insect prey, including the Mole Cricket, their favoured prey.

If Hoopoes were to return to the UK permanently, they would need suitable breeding habitats, such as open areas of short grass and soft soil where they can probe for insect prey coupled with areas of mature trees in which they can build their nests in natural holes (they do not excavate holes). Old buildings, stone walls, cavities, cliffs, among boulders, drainpipes, wells, roof spaces and nest boxes are also used as nest sites. Although they prefer Mole Crickets, in the UK other species of cricket, grasshoppers, millipedes, centipedes, spiders, woodlice, snails, slugs, ants, and occasionally even lizards and frogs would form a part of their diet.

What would you recommend to someone looking to watch Hoopoes in the wild?

To maximise your chances of seeing Hoopoes in good numbers and to hear their distinctive calls, I recommend visiting somewhere where they are a common resident, such as in Spain or the Balearic Islands. In Mallorca for example, one site I visit is called Son Real where it is possible to see up to a dozen in a single visit. Visit the type of habitat they like to frequent, especially olive groves and orchards and open fields with a good scattering of nearby trees. Scan the ground as this is where they will be feeding, but also look to the roof tops of derelict buildings or outbuildings or the lower branches of trees where they like to perch. If you are quiet and do not move too much, they will allow you to approach them without being disturbed. Also, listen out for their ‘oop-oop-oop’ call which sounds like their name. Be patient, you will see one. If you visit other locations there are sub-species too, such as the African Hoopoe and Madagascar Hoopoe.

Do you have any plans for any further books you can tell us about?

I am hoping this book is a success, as I have thought about writing another book about the European Bee-eater. I have already written a bird guide called Birds of Mallorca (available from NHBS) – it will be no surprise that the cover photo features a Hoopoe. I have another book which I have written called Not Quite Living the Dream, which is based on my attempts to reside in Mallorca and covers everything from wellbeing to birds, but I am hoping a sponsor comes on board to support me financially with that one.

The Eurasian Hoopoe: Everything You Could Want to Know About This Iconic Bird is privately published by Neville Davies and available from nhbs.com.

The Seal Project: Q&A with founder Sarah Greenslade

The Seal Project is an environmental conservation charity based in Brixham, Devon, which monitors, surveys and manages the welfare of seals on and around the South West coast, particularly Torbay and South Hams. Alongside seal conservation, the charity also focuses on engaging, involving and educating the community on the importance of protecting our ocean wildlife through presentations, talks, assemblies in educational settings, workshops and public events. Sarah Greenslade spent many years working as a key member of the British Divers Marine Life Rescue before establishing The Seal Project in January 2019.

Sarah, founder of The Seal Project, took time out of her busy schedule to answer our questions on the amazing work of The Seal Project, the effects of climate change on the local seal population, the importance of raising awareness, and how the current pupping season is going.

What is the Seal Project and where are you based?

The Seal Project is a small conservation charity based in Brixham that monitors the Grey seals in South Devon – mostly around Brixham, but we now also monitor the coast between Dawlish and Prawle Point, including the River Dart. The charity was born out of a need to protect the seals seen locally, many of which are animals we know individually from all around our stretch of coastline.

How did you get into seal conservation?

The story began when I encountered a Common Seal Pup stuck in Brixham’s Shoalstone seawater pool – who do you call at 5.30 in the morning? Myself and my best friend had no idea. The RSPCA don’t wake up that early and we had no clue what to do, but we knew that leaving the pup where it was wasn’t an option as people were walking dogs and the seal was clearly in the wrong place. My partner Lee (now a trustee of The Seal Project) suggested wrapping it up in something and putting it back in the sea. We had no hoodies or coats, so my friends partner was called and he brought down their most luxurious fleecey blanket off their sofa (as you do!) The seal, who had been swimming in the pool, came out and literally stopped at my feet. I scooped up the pup in the blanket as if it was a sleeping child and it never struggled once. We never touched it as we carried it over the rocks to the sea and let it free. As soon as we released it, another seal appeared – knowing what I know now that was most likely its mum – and off they went. The pup had clearly come in on a high tide and got stranded and the mum couldn’t get through the railings. If that was a grey seal it would have been abandoned there and then but Common seals are more devoted mums, and I hope to see this seal as an adult at some point.

After this, I became a Marine Mammal Medic for the British Divers Marine Life Rescue (BDMLR), which sends medics to call outs for marine life in distress, mostly seals, dolphins and whales. My first call out was to a ‘speared’ seal which quite literally resembled a tv ariel in the sea. She was eventually sighted locally without the spear attached, however it seems that every seal has some kind of back wound. She, like all seals, has unique identifying marks including their individual fingerprints and fur patterns, in this case a specific ‘W’ shape to the right-hand side of her head. I knew I had a photo showing that she was alive and well, and that resighting along with later identification of an animal known by the Seal Research Trust (Cornwall Seal Group Research Trust), with whom we share all our data, are what first sparked my interest in using photos to identify individual seals. After providing the identification I spent two weeks getting called out to every seal sighting in search of the previously speared individual, and it’s all gone a bit mad since then!

We are at the end of October, which is around the time Seals finish pupping. What has it been like in the Torbay area for pups this year?

I’ll be honest, it has not at all been as expected. Three of our known mums have not been seen for ages, and a first-time mum has been identified as a seal we know which we didn’t expect to be pupping just yet. The strange summer/autumn weather also means people are now using the coastline with their watercraft year-round and paddleboards and kayaks are now easily affordable too, so people are everywhere. Pupping seals who once had the coastline to themselves once September kicked in are now finding they don’t have these spaces to themselves, and as such pups are born or washed up in busy locations. This often results in a call out to BDMLR (as has just happened on the day I’m writing this).

Being based in a tourist area, what challenges do the seals and The Seal Project face?

That’s a good question. Hand feeding is probably our biggest problem. When we first started, our mentor and amazing friend Sue Sayer MBE thought that us starting a Brixham-based project would have a negative response as this is a major fishing port and some believe that seals ‘eat all the fish.’ But bar the odd comment, and a tiny number of incidents involving fishing and tripper boats hand feeding seals, we have experienced very few problems with the commercial operators in Brixham.

As a tourist area another big problem is angling-line entanglements. Our Breakwater is a busy area for novice anglers and they tend to feed the seals in an attempt to make them go away – clearly that doesn’t work. Also, some seals are sadly too habituated and get caught in angling line regularly. With adult seals there is nothing that we can do about this, and they have to be left to themselves until the hooks rust or fall out. Stones are also often thrown at seals to make them go away, and the animals are uncommon at a couple of locations where more ‘commercial’ land angling takes place.

Our biggest challenge is lack of awareness. We spend so much of our time trying to raise awareness and get the message out there which requires help from the local authorities and the tourist boats, but this doesn’t seem to be happening and it’s frustrating for us. We should all be working together, and the amazing local wildlife – including seals – should be respected and appreciated. Without our incredible wildlife many tourist boats would just be ferry services.

What projects or research have you been carrying out or got planned for the future?

We monitor and record all seals, sightings, dates and locations to try to build up a big picture of the seal population around our coastline. We now know many seals well and have been gathering data since 2016/2017. Matching our seals to individuals from Cornwall is difficult as there are very few other locations on the south cost carrying out monitoring in this way. Therefore, unless an image of a seal happens to be shared on social media or passed onto us from a private group, our records are mostly limited to the confines of our study area.

We do however have sightings of seals which have been released in Cornwall or seen in north Cornwall. We would love to be able to find out where else our seals have been seen and to build a better picture of their travels. Given that we do have Cornish seals visiting our area, we’d like to know if they behave differently to the individuals normally resident in Devon; my Cornish surveys show that the seals there are much more skittish than the individuals we see in Brixham, which tend to be relaxed and show little concern around the noise and traffic of this major fishing port. We do also have a couple of students planning research, but as of yet nothing is confirmed. Our data is not in the best shape and every sighting of each seal takes time to document – identifying one seal can take seconds or hours, and as this is all done by eye the catalogue is a minefield to get involved in!

How has climate change impacted the local seal community?

At this time, I can’t say for sure. My biggest concern is the fact that seal pups, born with white fluffy coats to be camouflaged in snow, are increasingly being born in hot September sunshine, and therefore once abandoned they are at a greater risk of dehydration due to being on sunny warm beaches when it should be much cooler. This year, numbers of seals appear to have been increasing unusually slowly as we head towards the winter months, but we’re yet to reach peak winter season to be able to confirm whether numbers will remain low. Our only other concern at this time is for the three mums who we’ve not yet seen pup this year, as they’ve been so predictable for the past few years.

Do you have a success story you’d like to share with us?

‘Easter Bunny’ is one of my favourite seals and can still be seen today resting around the local area. We first encountered him in 2020 as a juvenile seal entangled in industrial strength plastic. He vanished and we feared the worst, however a week later, on Easter Sunday, he was back in the same haul out spot on a girder in the marina, freed from the plastic. At the time of our first sighting, he appeared to have a bunny shape on his right-hand side (alongside a letter ‘A’), but this time the bunny seems to have disappeared with the ‘A’ is clearly visible. He reappeared regularly over the coming years, often seen for a few days and until the last several months always in the same spot, before disappearing for a few days and coming back again. We have seen him elsewhere a number of times, and last winter he was seen socialising with two ‘tagged’ seals (former rescued seals with plastic rear flipper tags for identification), so we look forward to seeing if they return to the area soon too.

Author Interview with Andrea Hart and Ann Datta: Birds of the World, The Art of Elizabeth Gould

Throughout her life, Elizabeth Gould’s work was appreciated mostly through her husbands projects documenting the birds of the world, including John Gould’s Exotic Birds, and she was therefore often not recognised under her own name. Following her tragic death at the age of 37, her artistic talents were nearly forgotten, and her name was completely unfamiliar in the art world.

Birds of the World: The Art of Elizabeth Gould is an incredible, one of a kind volume brought to you by Andrea Hart and Ann Datta, offering a remarkable tribute to Elizabeth’s artwork, reputation and skill. Containing over 200 beautifully detailed and scientifically precise illustrations depicting birds from 19th-century Europe, South America, Central America, Africa, Asia, and Australia, as well as previously unpublished artworks and an introduction to Gould’s life and achievements, this book is a lasting legacy for one of the greatest bird painters in history.

The authors kindly took the time to answer our questions about the inspiration and research behind the book – read our Q&A below.

Could you tell us a little about how you first began studying Elizabeth Gould’s work and the drivers behind embarking on this book project?

The Natural History Museum was initially approached by the publisher, Prestel, early last year asking if we might consider working with them on a book on Elizabeth Gould. As Andrea had already published a book on the women artists represented in the Museum’s collections and Ann has published a significant work on the correspondence of John Gould, this felt like a wonderful opportunity to bring the spotlight to Elizabeth and highlight her story and the incredible artist she was.

How did you gather the work for this collection? Did you have access to some of Elizabeth’s original plates?

The Museum’s Library and Archives has an incredible collection of books, manuscripts and artworks and is particularly strong and comprehensive in taxonomic works on natural history. Our rare books collection therefore has sets of all the Gould’s published works, including those published following Elizabeth’s untimely death. While we held some examples of Elizabeth’s original works already, notably the ones she completed for William Jardine, we were incredibly fortunate to have been permanently allocated an album of her and John’s original works through the Acceptance in Lieu scheme of Arts Council England. This publication therefore gave us a wonderful opportunity to share some of these historically significant original drawings with a wider audience, and to further appreciate her artistic talent.

Do you have some favourite images among the plates Elizabeth made?

This is a really tricky question as most of the illustrations that we chose are most of our favourites! Ann specifically likes the bowerbirds, the Narina Trogon, the quetzal and the Australian wren and Andrea became quite fond of the toucans (but also had to include a magpie).

It’s clear from the biography of Elizabeth Gould in your book that she was incredibly industrious and hard-working, and that she experienced a great deal in her short life during a remarkable period in history. Do you get a sense that Elizabeth Gould paved the way for more women to work as artists in this field?

There is no evidence that Elizabeth Gould was influential in inspiring other women to become bird artists due, probably, to her short life. After her death in 1841, Gould’s folios were continued seamlessly by the draughtsmanship of Elizabeth’s successor, Henry Constantine Richter. Only those who knew the Goulds intimately would have been aware of her early contribution to the success of the folios. John Gould went on producing bird books for another 40 years, their contemporaries died and few questioned who was the ‘E’ in the ‘J & E Gould’ plate credits in the earlier books.

Also, although Elizabeth may have been a promising artist as a young woman, it was not an easy career path to succeed in, and she chose to become a governess with more security. Elizabeth probably would not have become a bird artist had she not married John. John had the scientific knowledge to identify the birds in the preserved, dried skins and provided sketches to guide Elizabeth’s meticulous watercolours. They were truly an equal partnership.

During Elizabeth’s lifetime, plants were a much more popular subject for women artists to take up than animal subjects, and a few women who were Elizabeth’s contemporaries were successful in this line. But in general, there were few opportunities for women to follow a successful career in art.

I found it fascinating that many of Elizabeth’s plates are made using a lithographic process. I wonder if you could elaborate a little on that process and the time it would have taken to produce an individual plate?

All Elizabeth Gould’s published plates for John Gould were made by the lithographic process. Lithography seems a very strange process but in the 19th century it was adopted by hundreds of aspiring artists of all subjects – history paintings, genre scenes, topography and natural history. The lithographic method dominated print and book plate production in the 19th century replacing the more expensive engraving process. By using lithography, artists could make monochrome prints of their original paintings which they could sell to the public – the rising middle classes who wanted affordable art to hang in their homes. Learning and doing the lithography themselves had two advantages for the artists: total control of the print-making process and avoiding the expense of hiring a lithographer. Those artists who mastered the technique, such as George Scharf, had no need to go to the extra expense of adding colour as they could create great delicacy of tones and lines in landscapes and street scenes etc, just by adding shading and stippling effects on the stone. Some of the most acclaimed natural history artists such as Edward Lear (contemporary of Elizabeth) and Joseph Wolf learned lithography. Lithography was especially well-suited to reproducing bird plumages, from soft down to large feathers.

The process of lithography consists of drawing or painting with greasy crayons and inks on fine-grained limestone blocks. At the lithographic printer, where the stone would be taken after the artist had finished, the stone would be moistened with water. The parts not covered by the crayon would become wet while the others where the greasy drawing was made would repel the water and remain dry. In a special lithographic press the printer would rub an oily ink with a roller over the stone. The oily ink would adhere only to the drawing but be repelled by the wet parts of the stone. After a sheet of paper was pressed against the inked drawing an exact copy of the original on the stone would be transferred to the paper but in reverse. The process would be repeated until the requisite number of prints was taken after which the stones would be cleaned for the next person, although the stone with its original drawing could be preserved for several years. The stones were very heavy. A Gould plate measured 22 × 16 inches. A stone measuring 18 × 22 inches would be about 3 inches thick and weigh 100 pounds.

The lithographic printer Charles Hullmandel was responsible for all Elizabeth’s plates. His book, The art of drawing on stone (1824), has a vignette on the titlepage of a woman working on a stone. The first prints that came off his printing press – proof plates before lettering – were sent to Gould to approve. Then they went back to Hullmandel for him to add lettering to the stone according to Gould’s instruction (title = bird name, credits to the names of the artists, lithographer and printer). The proof plate after lettering, still a monochrome print, would go back to Gould again for her to colour to match her original watercolour. This artist’s colour proof would go to Gabriel Bayfield, the proprietor of a firm of colourists used for all Elizabeth’s plates, for his employees to copy the proof print on the requisite number of copies of each plate that Gould ordered.

Using this complicated and time-consuming process, each title took several years to complete. The books were sold by subscription (maximum number of subscribers often 250) who received parts, perhaps four times a year, and each part might contain 20 hand-coloured plates. The time taken to produce a lithograph would depend on the competence and confidence of the lithographer, and the complexity of the subject.

Elizabeth’s life contained many intense hardships. Aside from her incredible artworks, is there much record of her personal life and experience, such as in letters and diaries?

Very little extant information exists about Elizabeth with only about 15 letters dating between 1838 and 1840 surviving, all of which are now preserved in the Mitchell Library in Sydney, Australia. They were written by Elizabeth to her mother and cousin who had moved into her house in London to look after the children while Elizabeth and John were in Australia. The letters record some details of their visit including the people she met, especially Sir John and Lady Franklin, who accommodated them for nearly 12 months in Tasmania. Other topics include some of the problems faced by European settlers, e.g. acquiring servants, schooling, and the adverse climate, John’s collecting trips and his helpful Aboriginal guides, and making plant drawings. She writes proudly about her new son Franklin, born in Tasmania in Government House, and regularly enquires about the health of her mother and children. She does, however, reveal profound sadness at being away from her three young children in London.

In addition, there is one earlier letter written by Elizabeth in 1827 to her mother when she was working as a governess in London before her marriage. Only a fragment of a diary written by Elizabeth over the few days from 21st August to 30th September 1839 is known. It was written after she had left Tasmania and travelled to New South Wales to stay with her brother Stephen Coxen. In it she describes seeing several unusual birds.

From other sources it is possible to glean a few snippets about John and Elizabeth’s life in London. For example, she travelled with John to visit museums in Europe, and she probably accompanied him on some visits to Sir William Jardine’s estate. In a letter to Stephen, John Gould wrote in May 1841 that all the family had gone to stay in Egham for four months (Egham was then a village in the country).

In what ways does the industry of art for scientific publications differ today? Are there any similarities to the time in which Elizabeth was active?

Elizabeth Gould’s bird drawings served the scientific community. Accuracy of posture, colours and pattern of plumage and external anatomy were particularly important, alongside the impact of an attractive image, all of which are still required for taxonomic identification today. This could be achieved by painting the figure on a branch or on the ground according to its natural habits, often in a profile position. For Elizabeth, we believe, she would have started with a pencil outline, following the sketch that John would have made to assist her assemble a life-like figure from a dried bird skin. Elizabeth’s first meticulous drawings were rather conventional figures of very static birds – a style which persisted for many years until it was broken by John James Audubon in the early 19th century. Audubon spent many years in the field in North America and was the first to successfully paint the birds in their authentic natural habitat. Influenced by Lear and Audubon, Elizabeth would gradually develop her technique to produce more lively birds reaching a pinnacle in the Birds of Australia with the inclusion of appropriate flora and landscapes.

Today, an aspiring artist might attend art school before specialising in natural history art. Those who progress onto becoming wildlife artists would still observe their subjects in the wild and have additional equipment and technology to assist them, including binoculars and digital cameras to record and perfect their art. The detail required remains the same in terms of studying the subject’s internal and external anatomy and showing in their illustrations the required detail to be able to determine differences between species.

Bird art, however, includes many different styles and techniques which can change according to the artist’s preferences or the client’s requirements. There is, for example, a particular style used in field guides to compare large numbers of species on a page. Bird monographs, on the other hand, might just focus on a particular family and devote a whole page to an image of just one species showing male, female and juveniles, and so there is endless variety depending on the nature of the publication. Some bird artists, such as John Busby, also have a uniquely ‘casual’ style that is perfectly capable of depicting birds accurately and recognisably, but is very different from that of a more traditional modern bird artist such as the brilliant Robert Gillmor, who sadly passed last year. Those that illustrate for scientific purposes would also, just like Elizabeth, need recourse to examining bird skins or taxidermy in museum collections at some stage in their work.

Digital photography has certainly made images of birds and the natural world more widely available for guides and species identification, but there is still definitely a demand for artists to illustrate new species and produce illustrations and detail that is not possible to achieve with a camera.

Do you have plans for any future projects or publications that you’d like to tell us about?

There are so many other collections and artworks held by the Natural History Museum that would be amazing to research and publish on. For Ann, who did publish a significant volume on the correspondence of John Gould, she has some additional research papers to complete and, if time permits, would like to publish a biography of Thomas Hardwicke, who was an army officer and naturalist in India. Andrea would like to work on the botanical artist Worthington George Smith and the natural history artist Denys Ovenden in addition to developing a new temporary exhibition on artworks in the Richard Owen collection at the Museum, for display in the Museum’s Images of Nature Gallery in 2024.

Interview with Stephen Moss, author of The Owl: A Biography

The fifth and latest book in Stephen Moss’s captivating Bird Biographies series takes us on a nocturnal journal into the mysterious world of owls. Covering the seven species that can be found in the UK: the Tawny, Little, Barn, Long-eared, Short-eared, Snowy and Eagle Owl, this beautifully written and wide-ranging book effortlessly interweaves facts about their biology and ecology with snippets of folklore and tales from the author’s own experiences around the world.

Stephen Moss is a naturalist, author and broadcaster well known for his work with the BBC Natural History Unit working on landmark programmes such as Springwatch and The Nature of Britain. He currently holds the position of Senior Lecturer in Creative Writing at Bath Spa University and is also President of the Somerset Wildlife Trust.

Stephen recently took time out of his busy schedule to answer some of our questions about the book. We also chatted about the precarious status of the Eagle Owl in Britain, the likely impacts of the climate crisis on owls and his plans for continuing the Bird Biographies series.

A huge amount of research must go into writing a monograph such as this one. Did you learn or discover anything particularly surprising about owls during the process?

I always learn a huge amount about the subjects of these bird biographies! No matter how much you think you know about a bird’s lifecycle and cultural and social history, they always surprise you. Even really common species such as the Robin and Wren lead lives that we don’t totally understand. Because this book is the first in the series to include more than one main species (plus some material about other owls around the world) I learned something about every species – from the exact details of how Little Owls were introduced into the UK, to the many folk names of the Barn Owl, to how Tawny Owls dominate popular culture about owls. All absolutely fascinating, and will hopefully delight the reader!

What do you think are the most commonly held misconceptions about owls?

I think the main misconception about owls is that they are very rare – in fact there are about 50,000 breeding pairs of Tawny Owls in the UK, which is far more than Kestrels! Of course the reason we assume they are rare is that we hardly ever see them, because they are so nocturnal. I have seen Tawnies during the day, but only a handful of times in my entire lifetime. Other owls, of course, are far more diurnal (Little and Short-eared) or what birders call ‘crepuscular’, which means they are usually seen at dawn or dusk (Barn Owl). Only the Long-eared is as nocturnal as the Tawny – perhaps even more so, which is why we hardly ever see them! We also think of owls as friendly – or at least friendlier than hawks and eagles, which always look so fierce – perhaps because their eyes face forward, just like ours. And yet owls are lethal predators as well.

The final chapter in the book looks at the future of owls. How much do we know about the likely impacts of the climate crisis on owl populations in Britain?

Like any birds, owls are especially vulnerable to the climate crisis, and especially the unpredictable weather patterns, extremes of temperature, rainfall and drought, and the effects these will have on habitats and food supply – especially at a time when all bird species are facing issues such as persecution, pollution and habitat loss – and in the case of owls, also light pollution. And of course the Snowy Owl, which once bred in the northern extremities of the UK (on Fetlar in Shetland, where I saw one more than forty years ago) has now disappeared as a British breeding bird, and is very unlikely ever to return, as I explain in the book. Snowy Owls globally are also uniquely vulnerable to climate change, as they are the most northerly of all the world’s owl species.

I found the chapter on the Eagle Owl to be particularly captivating. However, opinions on its right to reside in the UK appear to be divided, even amongst conservationists. Leaving aside the argument about whether the species can be considered native or not, do you think concerns about its impact on other wildlife are justified?

This is a tricky one; and I do outline the arguments for and against Eagle Owls in Britain in the book. In some ways their impact on other wildlife is a red herring: as a top predator, their numbers are unlikely to ever rise so high that they cause major impacts on native species; indeed, if we want to save Hen Harriers (the occasional prey of the Eagle Owl) we would be better off dealing with their illegal persecution, rather than blaming the Eagle Owl.

Is there a species of owl you would still love to see in your lifetime?

Of all the world’s owls, I would love to see the largest – Blakiston’s Fish Owl of eastern Asia – and of course the smallest, the Elf Owl of North America. My son James lives in Japan, so perhaps I can look for the Blakiston’s Fish Owl when I visit him next year. But I’ve still only seen about 40 species of owl – about one in six of the world’s species, so there are plenty more to go!

Finally – what is occupying your time at the moment? And do you have plans to continue this series of bird biographies?

I’m just coming to the end of my dream job – teaching the MA in Nature and Travel Writing at Bath Spa University. I’ve led the course for eight years now, and loved working with such talented students and colleagues, but now it’s time to hand over to someone else, and spend more time exploring other projects. And yes, I’m working on a new bird biography – of one of my favourite birds, yet one that many people dislike – I’ll leave people to try and guess what that might be! I’ve got several ideas for future volumes and other ideas for books for the future. But I also want to spend more time with my grandson Sammy, who has just turned one, and get him into birding – and also travel, to see birds of course, in the UK and around the world.

Supplier interview with Faunus Nature Creations

Faunus Nature Creations is an ecological design agency established in 2018 as a subsidiary of NatuurInclusief. They focus on designing, building and selling fauna facilities to create nature-inclusive urban living environments and are widely recognised for their creative nest boxes. Most of their products are made in-house and they work closely with their suppliers and partners to ensure both functionality and beautiful design.

We had the opportunity to speak with Jarno Beijk, the founder of Faunus Nature Creations, about the company, their range of nest boxes and plans for the future.

What inspired the creation of Faunus Nature Creations?

Faunus wood concrete General Purpose bat box in black. — Faunus General Purpose Bat Box.

Faunus Nature Creations (FNC) was founded in 2018 as a business unit part of ecological consulting agency NatuurInclusief. At NatuurInclusief we regularly had to deal with mitigation projects as compensation for bat roosts getting disturbed. During field checks of these bat boxes, we discovered that the quality of the materials used were rapidly deteriorating. They did not meet any of the quality requirements and longevity that we wanted and expected from the bat boxes. From this moment the only solution we saw was to roll up our sleeves and design and build better nest boxes ourselves. Currently we are doing this with a team of ecologists, designers, engineers and architects.

Could you tell us about the range of boxes produced by Faunus and which animals they are suitable for?

In the beginning, our main focus was on roost boxes for bats, and nest boxes for House Sparrows and Swifts. The reason behind this choice is because they are the most strictly protected species by law. Fortunately, there is increasing awareness of building and designing in a more nature-inclusive manner, which means that there is increasing interest in nest boxes for other species as well. This includes species such as Kestrels, Storks, insects, and ground dwelling mammals etc.

Many of the boxes you offer are made from wood concrete. Could you tell us some of the benefits of using this material, both for the user and for the animal?

All our fauna facilities are designed with the needs and requirements of the species in mind. Wood concrete has a long lifespan, also the hydrothermal modified wood that we use has a lifespan of more than 20 years. It is therefore mainly down to the preference of the user.

Wooden facilities are not suitable as a build-in option. For this, the better choice is going for wood concrete or even better for a ceramic option. The latter have the longest longevity.

A great disadvantage of using wood-concrete and ceramics is that they do not lend themselves well for custom work. Therefore, wood is a very good option for custom work. That is why we make custom wooden bat boxes on request in all kinds of shapes and sizes. When customisation is required to be built-in, we make these on the basis of a cement board.

Personally, we think wood is the most beautiful for external use, because it looks more natural, but other people appreciate the concrete look as well. You will not easily find plywood in our collection, because we find this material is insufficiently durable and has too short of a lifespan.

Many of my colleagues have taken a liking to the names of your boxes, for example, Elisa and Gabriella. How do you decide these names?

Three Faunus bat boxes, models Elisa and Gabriella, on the side of a red bricked house during the day with blue sky in the background. — Elisa and Gabriella bat boxes.

Every nest box or new design we develop and offer is a new family member to our collection. Each design therefore deserves a unique name and not just a code or number. The intention was to use the names of people in our team first, but some found it quite embarrassing if they had to promote a nest box that would bear their own name. We have therefore given the names a slightly Spanish twist. So, Roos became Rosita and Eva became Evita. Spanish names also sound more swinging than Dutch names. At the moment we have more models than employees, so we have now arrived at names of relatives, neighbours and friends. Our latest model nest box Milo is named after the newborn son of our colleague Roos. Furthermore, the mammal nest boxes have female names, and the bird nest boxes have male names.

Have you found that environmental regulations have had an impact on the boxes you sell?

In the Netherlands we have a quite strict Nature Conservation Act. Our authorities require many strict mitigation standards concerning fauna facilities, for example in the form of bat roost boxes and nest boxes. This is a major reason that many of our clients need to buy the products we make. We ourselves are not in favour of this strict legislation, because people will lack intrinsic motivation to do something good for biodiversity in the end. We ourselves believe that you can achieve more for biodiversity if you know how to make people aware and enthusiastic to do something positive for biodiversity. Legislation of this mitigation standards leads to “must do”, enthusiasm leads to “wanting to do”.

What can you tell us about plans for new products in the future?

Faunus Nature Creations does more than just develop fauna facilities. Of course, we will bring new and improved models to the market, but we also design many large custom facilities for biodiversity, such as designing and building bat towers. We noticed that there is a great need for this as well. Governments and project developers would like to show off that they are doing something great and important to boost biodiversity and they would like to have the label extravagant for that too. We think it’s a sport to combine functionality, quality and aesthetics. Our motto is not without reason: Building for Biodiversity. Let’s create something valuable!

Faunus bird and bat boxes are available to order from nhbs.com.

Author interview with Graham Tucker: Nature Conservation in Europe

This informative and wide-ranging book examines the nature conservation responses of the UK and twenty-five EU Member States, analysing their achievements and failures and providing notable case studies from which comparisons and lessons can be obtained. Covering topics such as biodiversity pressure, legislation and governance, biodiversity strategies, species protection, protected areas, habitat management and funding, the book provides an incredibly in-depth appraisal of our management of European ecosystems and species and how this has contributed to the current concerning state of nature in these regions.

Editor Graham Tucker is an ecologist and a leading authority on European nature conservation policy, with a particular interest in its achievements and failures. He currently works as an independent consultant and proprietor of Nature Conservation Consulting. Prior to this he worked for Birdlife International and as Head of the Biodiversity Programme for the Institute for European Environmental Policy.

We recently chatted with Graham about the book and about the necessity for international co-operation in conservation, the importance of funding, stakeholder engagement and societal support in the creation and maintenance of protected areas, plus his plans for the future.

This is an impressive endeavour into covering the enormous topic of conservation across Europe. What inspired you to create this book?

Several things drove me to prepare the book. Firstly, like many others, I am concerned by the ongoing decline in many species and degradation of habitats in Europe, and that nature conservation has not been able to halt, let alone reverse most losses. Whilst there have been successes for some species, they have been insufficient, and consequently biodiversity targets have been repeatedly missed. Secondly, having had the privilege to work over the last few decades with many nature conservation experts across Europe, I realised the reasons for these failures varied between countries. Whilst the broad approaches to nature conservation have been similar, there have been significant differences, especially in their implementation and outcomes. Comparing national experiences could therefore provide valuable lessons in terms of which nature conservation measures have, and have not worked, and why. However, nature conservationists have tended to mainly draw lessons from national experiences, in part because of language barriers and the other difficulties with finding relevant key information.

Therefore, there seemed to be a need for a book that describes and critically examines the nature conservation objectives and actions that have been taken in Europe, primarily through individual country chapters written by national experts with a deep knowledge of what has really happened. Having discussed the idea with some nature conservationists I found that there was considerable enthusiasm for the book and many willing to contribute, despite the huge amount of work it would involve. This was also inspiring and persuaded me to go ahead as its preparation has depended on the hard work, generosity and patience of many people; of which I am especially indebted to the 52 co-authors.

Chapter 3 discusses the international drivers of nature conservation and their impacts on policies in Europe. How important is international co-operation and coherency in policy to nature conservation? Do you think there is enough large-scale international conservation?

International cooperation and coherence are vital for effective nature conservation. This is most obviously the case for migratory species, as well as rivers, seas and ecosystems that cross national borders, and transboundary protected areas. This has been widely recognised, so there is now a reasonably complete nature conservation framework in Europe, including the global UN Convention on Biological Diversity (CBD), the Convention on the Conservation of European Wildlife and Natural Habitats (Bern Convention) and, of most influence, the legally binding EU Birds and Habitats Directives. These agreements have aided cooperation such as through sharing programmes of work, knowledge and funding. Most importantly, they have helped raise ambitions by creating a level playing field – which gives countries the confidence to act, knowing that they would not be alone.

Unfortunately, the UK’s departure from the EU has undermined this cooperation and alignment, resulting in potential divergence in ambitions, policies and legislation, both between the UK and EU and between the UK nations. So far there has been little divergence in UK practices and standards are being maintained. But this could change with time, especially in England as a result of the Retained EU Law Bill.

Chapter 5, ‘Conclusions, Lessons Learnt and Implications for the Future’, mentions that, while nature conservation has likely slowed the rate of decline, many habitats such as wetlands and semi-natural grasslands forests have continued to be lost or degraded. Do you think large-scale commitments such as the one to increase the UK’s and EU’s protected area network to 30% of both land and sea by 2030 will generate the right amount of funding, stakeholder engagement and societal support to create effective, large-scale conservation?

I am sure there is wide public support for the improvement and expansion of the protected area network, both on land and sea, in the UK and elsewhere in Europe. This is because the potential nature and wider related social and economic benefits of protected areas are increasingly appreciated. However, in most countries it is more important to improve the effectiveness of the existing network, in particular with stronger nature conservation objectives and better practical management. This requires more funding and stronger regulation, which I am doubtful that most governments are currently committed to.

This chapter also mentions that nature conservation is dependent on enforced legislation, funding and motivated people. Which do you believe is the hardest to obtain and therefore is the biggest threat to current and future conservation efforts?

All three are needed, and they are to some extent interrelated and dependent upon each other. However, the lack of funding, which is in part due to insufficiently motivated politicians, is currently the main constraint in most countries. This hampers the enforcement of legislation, as well as limiting practical nature conservation and restoration actions in protected areas and the wider environment.

Whilst public support for nature conservation is substantial in many countries, especially the UK, it varies greatly. Political support also tends to lag behind public support, in part due to the influence of powerful lobbying groups. Wider and deeper societal engagement is therefore essential to stimulate stronger political support, funding and regulations. It is therefore encouraging that support for nature conservation is growing. This is needed now to counter recent calls from some politicians in the UK and EU to weaken some environmental ambitions and slow down actions.

What impact do you hope that this book will have?

I hope that the book will clearly show that nature conservation works when it is properly implemented – such that it can halt biodiversity declines and even restore ecosystems. Therefore, the ongoing biodiversity crisis is not because we are doing the wrong thing. On the contrary, we need to massively scale up what we are doing already. As said, we know what we need: strong and enforced regulations, more and better targeted funding, and more deeply motivated people to call for and help conserve nature. We should still seek to improve the effectiveness of nature conservation measures, basing policy and practical decisions on evidence, but be wary of calls for radical changes in approach.

Of all the countries discussed within this book, which do you believe are leading the way in nature conservation?

Unfortunately, this is not easy to answer as it is often difficult to reliably compare data across the countries. For example, some countries have large protected area networks (e.g. Croatia, Slovakia and Slovenia) in contrast to others (e.g. Belgium, Finland, Ireland and Sweden). However, the statistics are not always reliable as some countries, such as Bulgaria, Denmark and UK include areas that do not meet internationally recognised protected area definitions. Furthermore, the effectiveness of protected area network is not necessarily closely related to their size, but more their conservation objectives and the effectiveness of their practical management. Similarly, comparing the adequacy of funding is difficult because needs vary and it is not always clear how much goes towards species and habitat conservation priorities, and what it actually achieves.

As described in some detail in the conclusion chapter, all countries have both strengths and weaknesses, so it is difficult to identify overall leaders. As regards the UK, we have been leaders in some respects in particular in relation to science and the strong role of NGOs, and producing a wealth of strategies, including the first Biodiversity Action Plan in the world in response to the CBD. However, the UK has underperformed overall, primarily due to poor implementation of its strategies and other initiatives, largely as a result of limited political support and therefore weak regulations and inadequate funding.

Do you have any future plans that you’re able to share with us?

As the book has taken over five years to prepare, I am having a bit of a break from writing for the moment. But I am continuing to work on EU and UK nature conservation issues, especially in relation to climate change.

The impacts of climate change on nature are of growing concern to me, as I think they will be much worse than many people realise. In addition to the increasing disruption to ecosystems, there is the likelihood of huge impacts from climate change mitigation measures and adaptation actions over the next 30 years. Whilst it is essential to reduce greenhouse gas emissions, many proposed responses can be highly damaging for nature, including widescale inappropriate afforestation, use of bioenergy, solar farms and hydro-energy. Damaging climate change adaptation measures are also likely to increase, such as increased water abstraction from wetlands, as is already affecting the Coto Donana in Spain. At the same time, well designed ecosystem-based measures can contribute substantially to mitigation and adaptation, whilst being beneficial for nature – but these are being underused. Maybe, in time, I will prepare a book on this.

Interview with Jan Collins: Bat Surveys for Professional Ecologists 4th Edition

The 4th edition of Bat Surveys for Professional Ecologists: Good Practice Guidelines is the latest update of the Bat Conservation Trust (BCT) Guidelines and features new content on biosecurity, night-vision aids, tree surveys and auto-identification for bat sound analysis. Several key chapters have been expanded, and new tools, techniques and recommendations included. It is a key resource for professional ecologists carrying out surveys for development and planning.

Jan Collins is the Head of Biodiversity at the Bat Conservation Trust and a former ecological consultant. Her fascination in bats began when participating in a bat biodiversity survey on a Vietnamese expedition in 1999 and she has worked in bat conservation ever since. She has been in her current role for the last 10 years and has played a central role in the editing and refining of the BCT Guidelines.

In this Q&A we had the opportunity to speak with Jan about some of the key aspects of the 4th edition of the BCT Guidelines and its consequences for ecologists.

What led you towards a career specialising in bats?

From a young age I was interested in being outdoors and engaging with nature. My studies followed this route, with a degree in Environmental Sciences and a Masters in Ecology and Management of the Natural Environment. I was first introduced to bats on a Frontier expedition to Vietnam in 1999 where we were trapping bats as part of a biodiversity survey. I was immediately hooked (what an amazing group of animals, with unique behaviours, and so very diverse!) and sought both voluntary and paid work involving bat conservation upon my return. I was an ecological consultant specialising in bats for over 10 years before joining Bat Conservation Trust in my dream job as Head of Biodiversity almost exactly 10 years ago now.

Could you tell us briefly about the work that the BCT does?

BCT is a dynamic, influential and growing national charity. We are the leading non-governmental organisation in the UK devoted solely to the conservation of bats and their environment. Our work represents the gold standard in bat conservation providing a lead for the rest of the world. We work to ensure that bat conservation is acknowledged as an integral part of sustainable development. Our work ranges from best practice guidance, advice and training through to engaging wider audiences so that we can get more people to understand the importance of bats and their conservation. A lot of our work also involves working with partners on the ground, local bat groups play a huge role in all aspects of our work. More information about all of our work can be found in the most recent annual review, found here or take a look at the Bat Conservation Trust Website here.

The 4th edition of Bat Surveys for Professional Ecologists: Good Practice Guidelines is due to be published in September 2023. What have been some of the key challenges in getting this ready for publication?

One of the key challenges for this edition was gaining consensus from the Technical Review Board on some of the recommendations. This included the continued use of transects for bat activity surveys and how tree surveys for bat roosts should be carried out, acknowledging the various limitations, and how approaches should be adapted to different types of projects. Another challenge has been how much to include on night vision aids such as infrared cameras. BCT are planning a kick-off meeting for a working group to develop separate night vision aid guidelines in the autumn (to include infrared and thermal imaging cameras) and therefore many aspects are still to be discussed and decided. We will also run a public consultation on night vision aids to help us to understand current practice and expectations from new guidelines on this topic.

How has the outlook for bat populations in the UK changed since the last edition of the Guidelines?

Data from the National Bat Monitoring Programme indicate that populations of the bat species we monitor in the UK are stable or recovering. However, it should be remembered that these trends reflect relatively recent changes in bat populations (since 1999 for most species). It is generally considered that prior to this there were significant historical declines in bat populations dating back to at least the start of the 20th century. This suggests that current legislation and conservation action to protect and conserve bats is being successful, and it is vitally important that this continues. Detailed information on trends for the 11 species monitored can be found in our National Bat Monitoring Programme reports here. We are also seeing signs of regional variations that deviate from the overall positive trend at the national level and we want to gain a better understanding of those. More data would help this process so we would encourage everyone to join in with one or more of the National Bat Monitoring Programme surveys. There are surveys that are suitable for anyone regardless of experience or equipment.

What are some of the key changes in the Guidelines?

A number of chapters have been expanded and new tools, techniques and recommended best practice incorporated. Below are a few of the changes but we will be developing a webinar in the coming months, detailing all of the changes so readers should watch out for that!

A new section on Biosecurity has been added to Considerations for Bat Surveys chapter, recognising that precautionary approaches are needed to protect both ecologists and bats from potential health risks.
Chapter 6 on Surveying Trees and Woodland for Bat Roosts has grown from five pages in the 3rd edition and now includes details of newer technologies and sources of information such as night vision aids, motion activated camera monitoring, The Bat Tree Habitat Key and the Bat Roost Tree Tag Project as well as updated guidelines for categorising the suitability of potential roost features.
Chapter 7 focuses solely on dusk emergence surveys, with dawn re-entry surveys removed as a standard approach due to the improved quality of emergence surveys with night vision aids and the variability in the time that bats return to their roosts.
Chapter 10 on Data analysis and Interpretation incorporates information on auto-identification systems and has a new section on data science which includes details on elements such as tidy data, minimal data requirement and data standardisation. There are also case studies to help illustrate key points.

How will the new Guidelines improve the way ecologists approach bat surveying?

The guidelines are the key resource for professional ecologists carrying out surveys for development and planning. The Biosecurity section in the 4th edition will ensure that ecologists carry out their work in a safe way, minimising health risks to both themselves and to bats. The latest edition acknowledges the constraints involved in surveying trees for bat roosts and offers different approaches to surveys depending on the nature, scale and timeline of the project. A new categorisation system for Potential Roost Features (PRFs) and trees reduces the subjectivity in initial assessments of trees. Dawn re-entry surveys are no longer recommended as there are questions around their efficacy for presence/absence and because emergence surveys can be vastly improved by the use of night vision aids. A stepwise approach is offered to those using auto-identification systems to analyse acoustic datasets and the section on Data Science aims to standardise approaches to data management. The guidelines also make reference to a wealth of resources that can be used to improve surveys and, in particular, interpretation of survey data.

Nocturnal survey equipment such as night vision, thermal imaging and infrared cameras are becoming more important in bat survey with the 2022 Interim Guidance Note providing clarification of their role. How will the 4th edition of the Guidelines impact the way ecologists conduct bat surveys using these types of equipment?

The 4th edition supercedes (but is consistent with) the Interim Guidance Note published in May 2022. It emphasises that surveys should usually be carried out with night vision aids and that if they are not used this should be justified in reporting, with reasons provided (e.g. at known roosts when bats are known to emerge early or in situations/locations with higher levels of natural or artificial light). Dawn re-entry surveys are no longer recommended as a standard approach because the use of night vision aids vastly improves the quality of emergence surveys, when used properly. The new guidelines state that a still shot must be taken at the darkest point of the survey to show the field of view and that appropriate illumination has been used. They suggest that the use of night vision aids can be used to reduce the number of surveyors but only if the cameras/lighting reliably match or exceed what a surveyor can achieve, with evidence provided. See the 4th edition for more information on use of this equipment!

BCT are planning a kick-off meeting for a working group to develop separate night vision aid guidelines (with much more detail) in the autumn (to include infrared and thermal imaging cameras) and therefore many aspects are still to be discussed and decided. We will also run a public consultation on night vision aids, to help us to understand current practice and expectations from new guidelines on this topic.

Author interview with Arnold Cooke: Tadpole Hunter

In Tadpole Hunter, author and conservationist Arnold Cooke provides us with a personal and unique insight into the history of amphibian conservation and monitoring within Britain. As well as telling the story of amphibian natural history since the 1960s, it also provides a very human perspective on how we got to where we are today and how our knowledge of amphibian populations and dynamics has progressed over the second half of the 20th century. Packed with wonderful photographs along with charts and tables representing monitoring data, this accessible book will appeal to anyone interested in amphibians and the history of conservation in Britain.

Arnold Cooke was a researcher and advisor for the the Nature Conservancy and Natural Conservation Council for 30 years. Since leaving English Nature in the late 1990s he has continued to pursue his interests in amphibians, birds and deer and has published widely on subjects as diverse as the status of Britain’s amphibians and reptiles, pollutants in birds and the environmental impacts of introduced species of deer. His previous book, Muntjac and Water Deer, was published in 2019.

In this Q&A we chat with Arnold about his work with amphibians in the UK, the changes he has seen during his years working in conservation, and his hopes for the future of amphibian populations.

Although working with amphibians and their conservation has been a key part of your career, you have also dedicated a lot of your free time to recording and monitoring them and adding to the general body of knowledge regarding their populations. What is it about amphibians that you find so fascinating?

Amphibians have always appealed to me particularly because they can be relatively easy to catch – at least for vertebrates. However, they could be quite scarce where I grew up, and as a boy I was more interested in birds, flowers and invertebrates. When, in 1968, I joined the Nature Conservancy team studying the impacts of pesticides on wildlife, there were indications that frogs had declined, possibly because of pesticide use. An attraction of such a project was that there were significant gaps in knowledge about the natural history of frogs and other amphibians. This meant I had a fairly blank canvas at the beginning and I needed to undertake basic studies to try to understand what made frog populations tick, as well as doing pesticide studies. Later, I joined the Nature Conservancy Council, and became involved with conserving amphibian species nationally. By then I had started studying amphibians in a personal capacity, and was able to adapt or start local projects to inform issues of national interest, such as developing monitoring methods and investigating population stability and responses to impacts of various kinds. As information from these studies became available, it could be fed back into the system to conserve amphibians – and so helped me do my job more effectively. Once started, I became increasingly hooked and often found it difficult to stop the various strands of work.

You mention how, early in your career, you were faced with the challenge of discovering how populations of amphibians had changed in the distant and recent past and that, given the lack of empirical field data, sending questionnaires to suitable candidates was the best way to gather information about this. Do you think that conservation initiatives for amphibians are still limited by accurate population/distribution data?

When I started to work on the common frog more than 50 years ago, there was no hard information on how the national population had changed, but several well-informed individuals considered that declines had occurred. I felt I needed to be sure that there was a problem before doing too much work on pesticides and should find out whether, where and when decreases might have occurred. I targeted those people in the British Isles who had observed frogs (and common toads) in their local ponds and this resulted in information from several hundred sites. To increase cover I asked biology teachers in schools about changes in their local populations. The consensus was that there had been widespread decreases for both species during the 1950s and 1960s. This technique had obvious flaws, but its overall conclusion seems broadly accepted. However, it is wise to acknowledge the drawbacks of the method and not to place too much credence on the resulting information, especially on reasons that might be offered for change. Where ponds were destroyed (or created) in an area, then there are tangible reasons for change. However, this is often not true for suggested contributions such as from collection, road mortality or, indeed, pesticides. Because of the population dynamics of amphibians, substantial changes occur naturally and loss of some individuals does not necessarily translate into population decline.

During later decades of the twentieth century, several similar studies were undertaken, but since the turn of the century an attempt has been made to set up a statistically sound monitoring system for the widespread amphibians and reptiles. Unfortunately, number of sites covered initially was insufficient to provide a completely satisfactory basis for the scheme to go forward in that form. Consequently some modifications and compromises were needed, and a new approach has now started. Progress is being made employing novel field, laboratory and computer methods. And I am hopeful that herpetologists can continue to tap into citizen science projects on other animal groups, particularly birds, where huge numbers of competent individuals might be organised to gather additional data on amphibians.

I should also say that knowledge of the much rarer natterjack toad is exceptionally good. All known colonies are recorded regularly, and some have been monitored continuously for 50 years. This has allowed fine tuning of conservation action at specific sites and more broadly. And the very rare pool frog receives constant attention at its introduction sites.

As someone that worked at the forefront of conservation for many decades and has seen a huge number of changes, both in the natural world and in the human organisations and councils that are charged with protecting them, are you broadly hopeful for the future of British wildlife?

Thank you for the compliment, but I’m not sure how long I’ve spent at the ‘forefront of conservation’ – especially during the last 25 years when I’ve deliberately busied and buried myself in the detail of my own interests. Throughout my life, I’ve worked as a specialist in a range of disparate areas, rather than as a rounded generalist, so I’ve tended to focus on specific issues within the broad spectrum of wildlife conservation.

It’s true, however, that I’ve seen huge changes over the last 55 years. Some changes are of great concern – no one 50 years ago saw global warming coming. I remember there was talk about 40 years ago of the possibility of another ice age being just round the corner. The changes in biodiversity over that time have of course mainly been losses. On the other hand, there have been other types of change providing hope that British wildlife does have a reasonable future. I am thinking, for instance, of the numbers of professional people and volunteers now involved in conservation, the knowledge that has accrued, the conservation methods that have been shown to work and the legislation that has been passed. I’m aware that successive governments haven’t necessarily dealt kindly with environmental issues (or conservationists), but many peoples’ attitudes have changed markedly and younger generations are especially concerned about the environment. Just as conservationists in the past achieved more than might be expected because of their dedication, so should conservationists of the future – and there will be many more of them.

The wildlife communities and their distribution will, though, probably look very different in the future. I have lived for 55 years on the edge of the Cambridgeshire Fens. That area doesn’t sound very promising for wildlife, but I was pleasantly surprised to discover in 1968 that there were several nature reserves within easy reach including three important National Nature Reserves. However, I soon realised that reserves were like currants in a cake, there being very little of interest between them. When my wife and I drove to Norfolk to visit three other NNRs, we only managed to find one of them, despite knowing their grid references – and we had to negotiate a barbed wire fence to get into that. A permit was required for access in those days. The situation is of course very different now: visitors are generally welcomed. And reserves are increasingly being connected up, as is occurring in my area with two of the NNRs. I don’t doubt that much of our biodiversity will in future be experienced inside landscape-sized areas. I just hope it works. I regret that kids today don’t have the freedom that I had to explore and find things out for myself. Presumably, however, accessibility of knowledge will continue to increase. No need for children to learn and remember much, just use the phone app. Not wishing to be too cynical, surely enough youngsters will be captivated to become the dedicated conservationists of the future?

As regards amphibians, I believe we have more or less stopped the declines of the twentieth century and recoveries have started for some species. The future is uncertain but there are reasons to be hopeful.

Your working life has been incredibly fascinating and varied. Are there any parts of it that you remember with particular fondness or that stand out in your memory?

I’ve been very lucky with what I’ve been allowed or managed to do during my working life of more than 60 years – that’s using the word ‘working’ very loosely. I still have a reasonably good grasp of what I did and when I did it because I’ve usually written up (but not necessarily published) my observations and thoughts in some form or other. When I’ve been able to study wildlife, there has been very little that I haven’t enjoyed. There have been stand-out moments such as: in 1962 when I found my observations demonstrated that birds in suburbia were more approachable than those in the countryside; in 1982 when I watched breeding newts by torchlight for the first time; and in 1994 when I realised I could put out tempting vegetation for muntjac in a wood and find it had been consumed by the following morning. Each of these moments led to the development of field monitoring techniques.

Then there have also been periods that have been memorable for different reasons. The five years 1968-1973 with the old Nature Conservancy at Monks Wood were marked by an extraordinary level of interest in our work shown by the public, politicians and even royalty. In contrast, the last couple of decades have been spent quietly at home pottering around doing as much fieldwork as possible and sorting out what results meant. My qualifications are in chemistry and biochemistry and, had things turned out differently, I might have been more of a lab worker. But working outside has always been my preference. When working for English Nature in the 1990s, we were required to fill in risk assessment forms when away from the office, including when working outside normal office hours. Some years, I filled in nearly 200 such forms, revealing how much fieldwork I did as well as providing an illustration of why I was glad to leave behind modern management methods in the late 1990s.

What would be the main message you would give to the conservationists and ecologists that are following in your footsteps?

Because of my rather blinkered working experience during the current century, I think the most appropriate message is simply to say, ‘good luck and thank you’. Everyone needs some luck in order to have a satisfying career and I genuinely appreciate what present and future generations are doing and will continue to do to help understand and conserve wildlife.

Finally, what is occupying your time at the moment? Do you have plans for further books?

My main task this year has probably been seeing Tadpole Hunter to fruition, so it’s good to have it published at last. I’d wanted to review some of the topics in the book for many years, but they’ve only appeared in book form because of the Covid pandemic. My wife and I needed to shield during the lockdowns, so I started to review a couple of subject areas in March 2020. Later that summer, I realised that I had the basis for a book, so roughed it out and continued writing. I don’t intend writing another book, in part because of the time commitment. While writing Tadpole Hunter, I published several items on deer and have vague plans for other articles once the dust has settled from the book.

I have occasionally tinkered with bird behaviour in a very simple way and may revisit data collected in the 1980s. Earlier this year, I was surprised and very pleased to be invited to contribute my historic data to a global database of avian ‘flight initiation distances’, which precipitated a dive into material I hadn’t looked at for many years. Another line I might pursue concerns citizen science. I’ve participated in a number of such projects over the years, recording birds in particular, but also mammals and trees. At the moment, I’m interested in what an individual participant could get out of it? If repeated annually, it can provide useful monitoring information on species at your location. In some instances, I have carried on recording for long after the citizen science project finished.

Although I’m now doing very little fieldwork, I still have ideas to explore, but I’m sure there won’t be another book unless……….

Author interview with Mark Avery: Reflections

Reflections is a passionate commentary on the state of nature and conservation in the UK. In it, Dr Mark Avery explores the current condition of wildlife, why wildlife conservation is failing and what can be done to reverse its plight. He examines the role NGOs, land owners and government have in its failure, and crucially examples of successes too. Reflections is a valuable resource for those wondering what exactly is going wrong in nature conservation and what action can be taken to remedy this.

Mark Avery is an author, blogger and former director of conservation at the RSPB where he worked for 25 years. His previous works include Inglorious where he examines grouse shooting in the British uplands, and Remarkable Birds, a compendium showcasing the extraordinary wonders of the birds that share our world. We had the opportunity to speak to Mark about how he came to write Reflections and some of the key themes from the book.

Could you tell us about how you came to write Reflections?

I guess there are at least three reasons for writing a book. First, that you have a great imagination and can tell scintillating stories. Well, that’s not me and I write non-fiction, though I have wondered about a fictional book about nature conservation and nature conservationists. Second, you have some amazing experiences that you want to share with the world. That’s not me either. Third, you think you have ideas about the world that will be useful to others, and that’s the category that Reflections is in. I have worked in wildlife conservation for over three and a half decades and so I’ve lived the issues about which I write, but I’m not writing about my experiences, I’m writing about my thoughts, ideas and take on the world. Those ideas were bubbling up so much that I thought I’d write them down. It felt a bit like a pressure valve being released. The good thing from my point of view is that it seems that lots of other people relate to my thoughts. That’s thrilling for any author.

How do you think people’s attitudes towards, and awareness of wildlife have changed in your lifetime?

I was a teenager 50 years ago so looking back to then, animal welfare concerns, which aren’t quite the same as conservation concerns but are mixed together in all of our heads, have grown enormously. That affects how people think of field ‘sports’, predator control, snaring etc. I welcome many of those changes in attitude. Climate change has come along and dominates, rightly, the environment scene, and that has implications for wildlife conservation. I sometimes think that nature conservation is a bit squeezed between welfare issues and hard environmental ones. But over that period conservationists have moved from playing in small nature reserves and chasing people persecuting wildlife, to a greater force having some influence (not enough!) on big public policies such as farming, forestry and fisheries. We need to develop more strength in those political realms if we are to see nature recover.

You talk in Reflections about situations where considerable gains in wildlife conservation can be obtained in exchange for small losses in profit from land use activities. How do you think land managers can be convinced to take the hit to their profits for the benefit of wildlife?

With respect, I don’t accept the premise of the question. It is utterly pointless to try to get a vested interest like agriculture (house building, private forestry, shooting etc.) to act for the public good. Our wildlife conservation bodies are too timid and nice to realise that is a dead end. One has to jump over the heads of such industry representatives and persuade the decision-makers directly to implement public policies that deliver public goods. Focus effort on the decision-makers!

In the book you frequently mention the trade-offs between the state of wildlife in the UK and living standards. How do you think we can we balance the need for government investment in wildlife conservation and in critical public services like the NHS?

I’m glad you noticed that – we live in a complex human world and most people don’t give a stuff about wildlife. The partial answer to that question is that spending on wildlife conservation is tiny – that’s why it doesn’t work very well. It could increase many times over and still be tiny compared with other expenditures. It would be a false dichotomy to say we can have either a thriving wildlife or a thriving NHS, but I concede at the moment neither is thriving. Another partial answer is that governments should use more regulation (‘thou shalt not’s) rather than spending money on persuasion. They are cheap for the public purse. And of course, there are real benefits, that have economic valuations, in having wildlife-rich landscapes that flood less (or less damagingly), store more carbon and make people happier. But it’s a big subject. Give me a list of government spending across departments and I’ll cross a few things out (I might start with nuclear warheads) but your list would be different from mine, I guess.

You mention that the number of people actively interested in wildlife conservation is relatively small. How can we get more people to care about wildlife in the UK?

This is what our wildlife NGOs would call recruitment, or growing their memberships. The trouble is, it’s easier to recruit members than committed members interested in nature conservation. The National Trust’s five million members are arguably a weaker force for good that Wild Justice’s zero members but 35,000+ newsletter readers (but I’m maybe biased there). I think we could get more nature conservation done, particularly more impact on government policies, by getting existing members more mobilised than we could by getting more members. We have a small army of devoted conservationists – it’s just that they aren’t well armed with facts and tasks. Having more badly equipped troops isn’t a great recipe for success, I feel.

Do you think it is likely that we will see an improvement in the state of wildlife in the UK?

I can’t say that it is likely but it is certainly possible – but impossible with business as usual. We, and this means our largest wildlife charities, need to get much better at influencing land use policies. That’s entirely feasible but needs a change of mindset. I hope Reflections will encourage that change of mindset.

Do you have any plans for further books that you can tell us about?

I always have ideas, I have two at the moment, but sometimes they come to nought, so I’m not telling! Watch this space!
