Author interview with Richard Broughton: The Marsh Tit and the Willow Tit

The Marsh Tit and Willow Tit book cover.Marking the first monograph for either species, Richard Broughton’s The Marsh Tit and the Willow Tit reveals the remarkable lives of these wonderful little birds. Compiling decades of personal research, as well as a detailed review of external studies from across both Europe and Asia, it explores each species’ taxonomy, food and foraging patterns, social organisation, challenges and conservation, alongside more than 150 illustrations, maps, charts and photographs. 

Richard_K_Broughton.Dr Richard Broughton is a research ecologist with a wealth of experience across birds, mammals, forests and farmland in Great Britain and Europe. He has studied Marsh Tits, Willow Tits and their habitats for over 25 years, and prior to this he completed a Master’s degree in GIS as well as a PhD in Marsh Tit ecology, before joining the UK Centre for Ecology & Hydrology in Cambridgeshire.

We recently chatted to Richard about his inspiration for the book, which challenges he faced when developing such a detailed study of these two species and more.

You have studied Willow Tits and Marsh Tits for much of your career. What initially captivated you about these charismatic birds, and what inspired you to write a book about them?  

I had Willow Tits on my local patch in Hull when I was a youngster at school, and I had Marsh Tits and Willow Tits around my first office near Huntingdon when I started my science career. Both species were always a bit special and enigmatic – not so common that you saw them every day, but when you did it was like seeing parallel lives going on around you. They’re a lot like us, mostly preferring to live as couples in stable relationships, with busy social lives and a close attachment to their neighbourhood.  

From a research perspective, Marsh Tits and Willow Tits are fantastic species to study. They are widespread from Britain to Japan, they’re territorial and they don’t migrate, so the same birds are present all year round and you can really get to know them – how they communicate, organise themselves within their communities and solve the problems of living in different types of woodland, it’s all really fascinating. And there’s so much that we still don’t know, with lots of discoveries to be made, but also some urgency. We don’t fully understand exactly why they’re declining in many areas, so the inspiration for writing the book was partly to bring together all that we know about their ecology and what pressures they’re facing. If Marsh Tits and Willow Tits are struggling, then we need to listen to what this is telling us about our woodlands and forests. 

Willow Tit, Biaowiea Forest, Poland.Both species have suffered severe range declines – how can the general public work to better support these birds amid habitat loss and climate change?  

The main thing is to know where Marsh Tits and Willow Tits are still hanging on, and where they are declining – taking part in surveys and reporting sightings to the county recorders and BirdTrack are great ways of helping to monitor both species. Protecting and expanding their habitat is essential, but for that we need to know where they are, and in what numbers.  

It’s also important to realise how we can unintentionally make things harder for Marsh Tits and Willow Tits when we do favours for their competitors. There is growing evidence that increasing numbers of Blue Tits and Great Tits could be harming Marsh Tits and Willow Tits by taking over their nests and dominating their foraging space. The vast scale of bird-feeding in gardens, woodlands and nature reserves is changing our woodland bird communities, and it really boosts the dominant species, which can then put extra pressure on Marsh Tits and Willow Tits. For this reason, it’s important to consider the unintended negative impacts of well-meaning interventions, such as bird-feeding and nestboxes, on more vulnerable species like these. 

I was surprised to learn about the ineffectiveness of nest boxes in supporting Marsh and Willow Tit populations in relation to competition. Do you think this is also the case for other species across the UK, and what alternatives could we use to mitigate this issue?  

The problem with nestboxes for Marsh Tits and Willow Tits is that they’re far more likely to increase the densities of their dominant competitors, especially Blue Tits. If you add more nestboxes to a woodland then you will get more Blue Tits, but Marsh Tits and Willow Tits don’t work that way.  

This is because they have much larger territories, and you could fit 15 pairs of Blue Tits into a typical Marsh Tit or Willow Tit territory. These large areas contain enough natural nest sites for Marsh Tits and Willow Tits, and so these species are limited by the area of woodland habitat and not by tree cavities or deadwood for building their nests. As such, adding nestboxes cannot increase the numbers of Marsh Tits or Willow Tits like it does for Blue Tits.  

This shows how it is important to fully understand a species’ ecology for any conservation actions to work. A better solution is to promote diverse, wilder woodlands that have plenty of opportunities for Marsh Tits, Willow Tits and other woodland species at more natural densities. If not over-managed, woodland can quite quickly develop enough nesting sites on its own.

Within the book you mention the woodland restoration projects being undertaken in Scotland, which are striving to establish woodlands to support native species, including Marsh Tits and Willow Tits. Can re-establishing these complex habitats truly help to encourage population growth? And what would be your main recommendations for large-scale restoration projects with these species in mind?  

Expanding woodland habitat is a good way to help buffer Marsh Tits and Willow Tits from population declines, as the losses in Britain are greatest in areas of more fragmented habitat. In Finland, too, logging and habitat loss is driving population declines. Increasing the amount of woodland reduces habitat fragmentation, which in turn helps birds to disperse across the landscape and provides space for more breeding pairs, so it can only help. The natural range of Willow Tits, and probably of Marsh Tits, once covered much of Scotland, and so restoring forest cover in that country could help to re-establish their populations.  

Looking ahead, Scotland could eventually provide an important refuge for Marsh Tits and Willow Tits, being further from the intensive agriculture, urbanisation and more intense warming of southern Britain. We can look to other natural and regenerating forests in Europe to see what this restoration could look like in Scotland and elsewhere in Britain –  varied tree density and structural diversity, lots of standing and fallen deadwood, and plenty of water in streams, pools and soils. Where we still have such places in Europe, like in Poland’s Bia?owie?a Forest, then Marsh Tits and Willow Tits both find places to live in different parts of the same woodland. 

The Marsh Tit and the Willow Tit is very thoroughly researched and includes an extensive breadth of information. Did you encounter any challenges when developing such a detailed study of these two species?  

I was lucky that there have been major studies of Marsh Tits and Willow Tits in Europe over the past century, and I have been involved with several of them in recent decades, so I was familiar with their findings. For other studies, it has never been easier to find and access published papers and reports online, and even to translate them automatically. 

Nevertheless, it was still quite challenging to find many studies from Asia, which is where more than half of the world’s Marsh Tits and Willow Tits are thought to live, along with their closest relatives, the Black-bibbed Tit, Caspian Tit and Sichuan Tit. This is slowly changing, as more research is being done in China, Japan and South Korea, but there are still large gaps. In Europe, too, we still know relatively little about Marsh Tits or Willow Tits in some regions. Even in Britain, the recent discovery of a previously unknown population of Marsh Tits in the Scottish Borders shows that we still have things to learn! 

 Marsh Tit at its nest, Biaowiea Forest, Poland.What have been some of your favourite moments while researching this book? And did any of your discoveries surprise you?  

It’s been a great pleasure to look back through all of the previous studies of Marsh Tits and Willow Tits and pay tribute to the dedicated researchers who spent so many years in the woods and forests, peering into the lives of these little birds. What shone through for me is just how connected the forest ecosystem really is. Marsh Tits and Willow Tits are part of a complex web of life, with some really surprising relationships. For example, Bison and Red Deer stripping bark from trees helps to create the cavities that are the Marsh Tit’s favourite nest sites. Meanwhile, Willow Tits forage on carrion from Wolf kills, which helps them to survive northern winters. At the other end of the spectrum, Marsh Tits and Willow Tits both drink nectar from blossom and might be significant pollinators of woodland shrubs, and they might also be seed dispersers for some woodland plants.  

We’re just starting to understand these relationships, but in many parts of Europe they have been broken by the loss of forest species, such as large mammals. It’s exciting to think that nature restoration and rewilding could rebuild some of these ecological networks in our woodlands. Again, there’s still so much to learn about Marsh Tits and Willow Tits, but getting to know them opens a window into the wider forest ecosystem, and the more you look, the more you find. 

Finally, what is occupying your time now? Are there new books on the horizon that you can tell us about?  

I’m still monitoring my Marsh Tit population at Monks Wood in Cambridgeshire, coming up to 24 years of study, and I’m busy with interesting research at UKCEH on hedgerows, woodland regeneration, sustainable farming and nature restoration. In the past year I’ve been busy as the new Editor in Chief of the BTO’s scientific journal Bird Study, helping other researchers to publish their studies. I’m also still involved with research at the Biaowiea Forest in Poland, which always has exciting opportunities, and last spring I was there finding the nests of Marsh Tits, Willow Tits and Wood Warblers. The Wood Warbler is another declining woodland bird that has lots of really fascinating and surprising behaviour, and that’s another species that I think could be worth writing about.

Author interview with Ursula Clare Franklin: Mission Penguin

Mission Penguin book cover showing a King penguin and Gentoo Penguin on a beach.Following the loss of her husband, Ursula Franklin embarked on a mission to see and photograph every species of penguin in their natural habitat. In this breathtaking book, join Ursula on expeditions to some of the most remote places on earth, from the Falklands to Tristan da Cunha and Antipodes Islands, in search of these much-loved birds. Interspersed with stories from Ursula’s adventures, each chapter explores a different species of penguin, detailing their identifying features, the ever-increasing threats they’re facing, and the conservation efforts needed to ensure future generations can experience the wonder of these animals.

Ursula Franklin is a keen wildlife photographer who grew up in Yorkshire, and is now based in Somerset. She developed a keen interest in photography when she was a child and her wonderful husband supported her passion until his sudden death in 2012. As a way to process her grief and heal, alongside her husband’s constant encouragement for her to ‘do something with her photography’, Mission Penguin was born.

We recently had the opportunity to talk to Ursula about her expedition, how she thinks we can we work to protect these vital species in the future, her favourite memories throughout this journey and more.

Having travelled around the world and seen every species of penguin in every habitat, which species surprised you the most and why? 

Like many people, I had always associated penguins with snow, so it was amazing to discover that some species breed in forests, others in the desert and one species even at the equator.  The species that really surprised me, however, and for a totally different reason, was the Royal Penguin. This species breeds on Macquarie Island, and in the north of the island are the rusted remains of huge digestors which were once used to extract oil firstly from seals and then when they ran out, penguins. Millions of King and Royal Penguins were slaughtered leaving just a few thousand birds when the barbaric practice was finally stopped. Having suffered years of persecution by man, I marvelled at how trusting the birds were. As I sat on the beach, groups of Royal Penguins waddled up to me, inquisitively studying my boot laces, camera bag and equipment. They were so curious and seemed utterly fearless. It was hard to imagine humankind betraying such trust. Luckily, over the last 100 years, their numbers have steadily increased and in 2022 they were finally taken off the list of near-threatened species (IUCN red list). Hopefully they will continue to increase despite the human-induced climate change crisis.

You were lucky enough to witness the full, daily lifecycle of a number of penguin colonies by watching them from dawn until dusk, and I particularly loved the photographs of the Gentoo penguins on Saunders Beach at sunset. What does the typical day in the life of a penguin look like?

A day in the life of a penguin varies hugely depending on the time of year, especially during the breeding season, or when moulting. At other times of year, the birds spend their time foraging in the open ocean. During their annual moult, which usually lasts around 3 weeks, they are no longer waterproof so cannot go into the ocean to feed – instead they must stay on land living solely off their fat reserves. The breeding season is when they spend time on both land and sea. For most species, males and females share incubation of the egg/s and often take it in turns to go foraging to feed the hungry chick/s whilst the other parent stays to protect it/them.  With some species, as the chicks get older, they are left in a crèche, or some stay in a burrow, allowing both parents to go to the ocean to collect food for their increasing appetites. The birds often leave at dawn when foraging, and the length of time they are away depends on how far they must swim to find food. For some species, warming ocean temperatures have shifted prey populations further from the colony leading to chick starvation and mass breeding failure. When the parents do return with food, some species engage their older chicks in long food chases before finally stopping to feed them. This is done to build up the strength of the chicks prior to fledging and is hilarious to watch. The adults then stay with their chicks at the colony overnight before the whole process starts again early the next morning.

You travelled around the world and have seen so many different places as a result of this project – what was your favourite memory and why?

This is such a hard question. I could say the very beginning of the mission on the Antarctic Peninsula with the sighting of my first penguin – this was a Chinstrap Penguin and has since become my favourite species, probably because the black strap under their chin makes it look as if they are smiling. Or I could go to the very end of the mission at Snow Hill Island with the Emperor Penguin colony, which was like being on the film set of the movie Happy feet and a very fitting and emotional accomplishment of Mission Penguin.  

My favourite travel destination, however, is the Falkland Islands. With fewer than 4000 people, beautiful coastlines and over one million penguins of five species I’m sure you can understand why. My favourite island is Saunders Island and my favourite location there is ‘the neck’. The accommodation is very basic and although small can technically sleep 8 in 4 sets of narrow bunk beds. Incredibly, on my last visit, my friend Hazel and I were the only occupants – apart from the penguins of course! What a joy and privilege to be the only humans sharing their world and a memory that will stay with me forever.

Having witnessed first-hand the negative effects of both climate change and human activity on penguin colonies, and their respective habitats, how can we work to protect these vital species in the future? 

Penguins are key indicator species for the health of our oceans and the effects of global warming. Although there are no penguins naturally occurring in the Northern Hemisphere, our everyday actions here will ultimately filter down to the Southern Hemisphere and affect these animals. 

One of the most threatened penguins is the African Penguin, and research suggests that this species could become extinct in the wild by 2035 unless we act now. Whilst we have little influence on African governments regarding marine ‘no-take’ zones, limiting coastal development, (oil refineries etc) can still help. For example, all of us can reduce our use of plastics (especially single use), and switch to renewable energy sources. 

For more direct and immediate help we can also sponsor penguin nest boxes. African Penguins naturally lay their eggs in burrows which are dug out of layers of guano (bird poo!) laid down over hundreds of years. In the 1800’s most of this guano was collected and shipped to the UK to be used as fertiliser. As a result, there has been a 99% decline in the population over the last 100 years. As land temperatures continue to rise, penguins now nesting out in the open air are either dying from hyperthermia or abandoning their nests to save themselves, leading to mass breeding failure. Carefully researched and crafted nest-boxes that replicate the conditions of a guano burrow are proving effective – to help visit the Saving Penguins website. 

A shortage of suitable nesting sites mean breeding African penguins are exposed to the full heat of the sun often with disastrous consequences.

Photographing every species of penguin is no small feat, especially alongside a full-time job! What were some of the biggest challenges you faced and what did you learn along the way? 

When I announced to a friend that I was going to photograph every species of penguin in their natural habitat, I had no idea how many species there were or where they could be found. My research took me to places that I had never even heard of and to say many of them were ‘off the main tourist route’ would be an understatement! Simply getting to the required and often incredibly remote locations was definitely the first challenge. Many of these are also found in the roughest oceans in the world, and I suffer dreadfully from sea sickness. Needless to say, I was often very unwell but even that could not detract from the awe and wonder of these amazing expeditions. Once at the location, sometimes I only managed fleeting glimpses of just a few penguins of that species so not many photographs, but I appreciate how very lucky I was to actually see and photograph every penguin species on the first attempt. 

The weather also presented significant challenges (especially the wind), and trying to photograph from a Zodiac (Rigid Inflatable Boat) while being tossed around in large swells was at times nigh on impossible. I also needed to keep my equipment warm in Antarctica and dry in the humidity of the Galápagos. Sunshine, although lovely in itself, also made photographing black and white birds more difficult than normal in terms of achieving correct exposure. I certainly learned to tolerate imperfections but also became a better photographer along the way. I also witnessed firsthand how tenacious and resilient penguins are – characteristics that we can all learn from. 

The strong wind blowing the crests of these Moseley’s rockhopper penguins also made photographing them more challenging.

Mission Penguin came to fruition as a result of loss and grief, and throughout the book I found it heartwarming to read about the healing effects of your expeditions. How important do you think nature is in healing from grief, and what are the benefits of spending time exploring the natural world? 

Nature is indeed an incredible healer. I have lovely memories of my mother taking us out on nature walks when we were young as we didn’t have much money, and nature was all around us and free! I think from that age I learned to appreciate the wonder of nature and delight in simple things, so when grief struck, getting out in nature and reconnecting with life and beauty was essential to my healing. Nature stimulates all of our senses which certainly helped me to feel fully alive even in the context of death. What inescapable joy to hear the birds singing, see the dappled light in a woodland glade, smell the flowers, taste the salty sea air, and hug a tree! Being immersed in the natural world really helps to put things into perspective and to feel part of something much greater than ourselves. In nature I feel fully grounded which gives me an inner peace and the strength to keep going, one step at a time.

What’s taking up your time at the moment? Are you working on any other projects or planning any upcoming expeditions that we can hear about? 

Following the completion of Mission Penguin I have spent more time delighting in the natural world on my doorstep. In the last couple of years, I have finally taken up gardening, which my husband would have found hysterical having tried to persuade me all our married life! My focus however is gardening with wildlife in mind, and I think we would have had very different definitions of a ‘weed’! I am also rewilding one large area and quickly learned the hard way that rewilding is not the same as letting things go wild! I am still taking lots of nature photographs and readers can see more of my images here.  

As well as writing the book, I started giving talks on Mission Penguin to local groups and this quickly expanded to other topics as they keep inviting me back for more. I now have about 6 talks in my repertoire so that is keeping me busy as well as continuing with my singing – another fabulous activity for wellbeing.

Nest Boxes for New Build Projects

Nest boxes can be an excellent way to support biodiversity and incorporate additional habitat into new builds or redevelopments. Some nest boxes are specifically designed to cater to certain species, while others are more generalist and are suitable for multiple species. Generally, bird nest boxes consist of a large internal cavity and an access hole in various shapes or locations depending on the target species. They can be made from a variety of materials, however, woodcrete (or woodstone, woodconcrete) is generally preferred due to its robustness, longevity and advantageous thermal properties.  

As low impact, wildlife-friendly construction gains momentum, more choice is added to the market each day, and the range is extensive. We are pleased to offer the largest range of integrated nest boxes in the UK.  Here we provide an overview of some of our bestselling models and their benefits. 

Integrated swift box

Integrated Swift Boxes 

Swift populations have declined over recent decades due to changes in roof design and the choice of materials used to construct our homes and public buildings. This species typically uses existing holes, cracks and crevices to build their nests, especially those in old buildings, so built-in swift boxes are recommended to provide areas for these birds to roost. These boxes provide large internal cavities within the brickwork that can be accessed by horizontally elongated, often downward facing entrance holes. As colony breeders, it is recommended to site multiple swift boxes together, situated with a clear flight path. The boxes should be installed at a minimum height of 5m on a non-south facing wall and should have no less than 40cm between entrance holes.

Birds of Conservation Concern Red List: Species Spotlight

In September, five species of seabird were added to the UK Birds of Conservation Concern Red List. Arctic Tern, Great Skua, Leach’s Storm Petrel, Common Gull and Great Black-backed Gull have joined the list of species most in need of conservation. Each of these species has experienced population declines due to pressures including climate change, avian influenza and habitat loss. Over 30% of all British birds are now on the Red List; the most recent additions joining Kittiwakes, Puffins and Arctic Skuas, among others. An alarming ten out of 26 UK seabirds now feature on the list.   

In this blog we shine a spotlight on these seabirds and explore the threats that have resulted in their addition to the Red List.  

Leach’s Petrel (Hydrobates leucorhous)

Identification: Leach’s Petrel is a Starling-sized bird with a wingspan of up to 48cm. This burrow-nesting seabird is mostly black in colour, except for a white rump with a black line running through it. The wings are angled, with darker wingtips and a lighter coloured ‘V’ over the wingspan and the tail is dark and forked.  

Distribution: Most sightings of this species are recorded around coastal headlands and sea-watching hotspots during autumn. The UK has an estimated 48,000 breeding pairs which can mostly be found on remote offshore islands (particularly in Ireland and Scotland) before migrating to the tropics over winter.  

Threats: Leach’s Petrel was added to the Red List due to population declines and localised breeding concerns. It is thought that more than half of the UK’s population resides at fewer than ten sites, areas which carry the risk of predation by introduced mammalian predators as well as avian predators.  

Fun fact: Leach’s Petrels spend most of their time offshore, close to deeper waters beyond the continental shelf, before returning to underground nests at night.  

 

Common Gull (Larus canus) 

A seagull standing on a rock. It has a yellow beak and legs, a white body and grey wings. The wings are tipped with black.

Identification: A medium-sized gull with a wingspan of up to 130cm. This species is similar in appearance to the Herring Gull but is smaller in size. It is mostly grey from above, with a grey back and upper wings. The underside, head, tail and body are white. The small bill and legs of the Common Gull are yellow-green in colour and, up close, a red orbital ring can be observed around the iris. Their call is a high-pitched ‘kee’ or ‘kee-ya’ sound.  

Distribution: There are approximately 49,000 breeding pairs of Common Gull in the UK, which breed in the north and west of Britain and Ireland. They are generally widely distributed throughout the country but are found with the highest densities on the eastern side of Scotland. Predominantly a coastal bird, this species has a preference for upland areas and can be seen in towns along the coast throughout the year. 

Threats: Severe declines have been observed over the last 25 years, with over half of the breeding population lost during this time. These losses are due to a number of factors, including predation, habitat loss and degradation.  

Fun fact: Despite its name, this bird is scarcer than other gull species and is found in lower numbers.

 

Great Black-backed Gull (Larus marinus) 

A large gull flying over the sea. It has a yellow beak with a red patch. Its body is white but the backs of the wings are a dark slate grey

Identification: A thick-set, very large gull with a powerful beak. Great Black-backed Gulls are easily recognised by their black upper wings and an impressive wingspan of up to 167cm. The head, neck, tail and underside are white and there are visible white edges to the upper wings in flight. This species has pale pink legs, and a distinctive large yellow beak with a red spot on the underside towards the tip.  

Distribution: There are around 17,000 breeding pairs of Great Black-backed Gull in the UK which can be seen throughout the year in coastal locations. This species is found across the UK but has high densities around the northern Isles and south-west Ireland.  

Threats: Populations of Great Black-backed Gull have declined by an estimated 50% since 1985, brought on by suspected declines in food availability in their natural habitat, habitat loss and threats from entanglement and development.  

Fun fact: The Great Black-backed Gull is the largest gull species in the world. 

 

Arctic Tern (Sterna paradisaea) 

A small white bird with a black head. Its legs and beak are a vibrant red and the wing tops are a light grey
Image by Alaska Region U.S Fish and Wildlife Service via Flickr

Identification: A small, slender seabird with a wingspan measuring up to 85cm. The Arctic Tern is a white bird with a black cap and grey wings. It is streamlined in shape and has a deeply forked tail with long streamers. The legs and pointed beak are red in colour and their calls are hard and repetitive, with a ‘kee-arr’ sound.  

Distribution: There are approximately 54,000 breeding pairs in the UK that can be seen in good numbers around Shetland and Orkney. Arctic Tern can be seen from April to September in Britain, breeding coastally in the north.  

Threats: Arctic Tern populations have undergone long-term declines for several reasons: habitat loss, human disturbance in breeding and feeding habitats, impacted chick survival by avian influenza, and declines in Sand Eels, a critical food source. 

Fun fact: The Arctic Tern has the longest migration of any tern – this species breeds in the Arctic and travels south to summer in the Antarctic.

Identification: A large, dark brown bird with a wingspan up to 140cm. Great Skua are heavy in build and almost black in colour when viewed at a distance, with white flashes on the wing visible in flight. Up close, their plumage is streaked with black, brown, white and yellow and their bills and legs are black. They have a distinctive gull call – a harsh ‘hah-hah-hah-hah’ sound.  

Distribution: Great Skua can be seen around British coastlines throughout the year, with most sightings documented between April and November. This species is known to breed on northern islands, including Shetland and Orkney during the summer months.  

Threats: Great Skua populations have been severely impacted by avian influenza, resulting in at least 2,500 deaths of Scottish birds since 2022.  

Fun fact: Considered ‘pirates of the sea’, Great Skuas are predatory birds and will hunt small birds, rabbits and rodents.

Author interview with Stephen Moss: The Starling

The Starling A Biography cover.Marking the sixth volume in Stephen Moss’ Bird Biography series, The Starling delves into the fascinating life of one of our most talented and surprising birds. Starlings are renowned for their iridescent plumage, impressive vocal abilities and stunning murmurations, and this captivating tale explores how they’ve shaped our world, inspired art and music through the decades, influenced the agricultural industry and more. 

Stephen Moss portrait.Stephen 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 his latest book The Starling, including what inspired him to write about this species, how his opinions of this bird has changed throughout the writing process and more. 

The Starling marks the sixth volume in your bestselling Bird Biographies series. What inspired you to turn your attention to Starlings for this latest volume?   

I always look for three things when it comes to choosing a subject for a bird biography. 

First, does the species show some unusual or specific behaviour or habit which mark it out from other species? For example, the Robin’s habit of singing and holding territory in winter, the Wren’s bizarre breeding behaviour where the male builds several ‘cock’s nests’ for the female to inspect, or the Swallows’ epic migrations. 

Second, does it have a strong cultural presence – in music, literature, mythology, popular culture and day-to-day society? Examples include the Robin’s association with Christmas, the Swallow’s position as a herald of spring, the Swan’s royal connections, and the owl’s reputation as a mysterious bird of the night. 

And third, does the species relate to both me and the reader? Basically, is it one of Britain’s favourite birds, and if so, why? It also helps if I like the bird and have had a lifelong connection with it – which is true of all the species I have featured in the series so far – as then I can add personal anecdotes from my life as a birder. 

Just like the previous subjects in the series – the Robin, Wren, Swallow, Swan, and owl(s), the Starling fits the bill in all three of these categories. It is a very sociable bird – more so than almost any other species during both the breeding season and in autumn and winter, when they gather in those famous murmurations. There are also plenty of historical and cultural references, including the fact that Mozart kept a pet starling which used to whistle his new compositions, and which he mourned in a solemn burial ceremony after it died. Most of all, we have a love-hate relationship with this bird, giving it a real ambivalence in our eyes – which makes it a fascinating subject for a book. And as you mention later on, like most of us, I grew up with Starlings. I now live on the Somerset Levels, just a stone’s throw from the famous winter gatherings, which I have now enjoyed for almost twenty years.

This book explores how starlings have influenced both farming and the arts throughout the years – were there any discoveries that surprised you on this line of inquiry?  

The biggest surprise was that the widely known and oft-repeated story that Starlings were introduced into North America by a German emigrant who wanted to bring every bird mentioned in Shakespeare to the New World turns out to be mostly a myth! He wasn’t German (though he did come from a high-ranking New York family of German descent); he had no interest in Shakespeare, and most importantly he wasn’t the first person to release Starlings into the wild in the USA – that happened over 20 years earlier. Check out the chapter on ‘The Global Starling ‘to find out more details! 

 

You mentioned having been around starlings for most of your life in the first chapter. Has your research and writing of this book altered your opinion of these birds?  

Definitely! I do have a real soft spot for Starlings – though I also agree with the expert scientist Chris Feare that they look like second-hand car salesmen when they walk! I love the fact that they live alongside us but don’t really care about us – just going along with their day-to-day lives.  

I also discovered a lot more about the science of their murmurations, and also about our human response to them, which ranges from loathing to love.  

Finally, their ability to adapt to locations around the world where they have been introduced – including South Africa, Australia and New Zealand as well as North America – is also very interesting, and again tells us a lot about our ambivalent attitudes towards these fascinating and often overlooked birds.

Starlings are often regarded with distaste and annoyance by many. Are there any common misconceptions impacting people’s perceptions of this overlooked species? And how can we move towards acceptance, and ideally, appreciation of these birds?  

As my old friend and colleague Bill Oddie famously said, people think of Starlings as ‘bird table bullies’! And yet those same people who don’t like them in their garden love watching their spectacular murmurations! They are also often overlooked – like all common, familiar and widespread species, we tend to take them for granted.  

Yet paradoxically, as we saw when another common and familiar bird, the House Sparrow, started to go missing from our towns and cities, when we begin to lose a species, we do begin to appreciate them more!  

Starlings are in decline, and almost all urban roosts like the ones in the middle of London, including the famous one in Leicester Square that I used to see when I was growing up, are no more. Fortunately roosts in the wider countryside do appear to be making a bit of a comeback.  

If anyone still doesn’t like Starlings, I would urge them to come down to Somerset on evenings between November and February, where we still get a quarter of a million or more Starlings murmurating together before going to roost on the Avalon marshes – it really is truly incredible!  

 

How do you think the historical representation of ‘pest species’, such as Starlings, has affected our attitudes towards them, and how do you think we should approach the somewhat controversial topic of conservation vs agriculture vs pest control in the future?  

I don’t like the word ‘pest’, though it is at least a bit less loaded than ‘vermin’! As I discuss in the book, Starlings have always been unpopular with farmers, even though they predate on many so-called insect pests in the soil, such as leatherjackets. They do eat fruit and can also cause problems with their droppings, but overall, I think they are less harmful than many people think.  

I also believe that we tend to dislike species, especially those that live alongside us, that remind us of ourselves. This includes gulls, crows and of course starlings, which often seem to behave rather like us, and we don’t like that!

I, along with many of your readers, will be excited to see where this series will go next. Have you begun working on the next book? And can you give us any clues as to what comes next?   

I have, although I am taking a bit of a break from writing as I am trying to get a better work-life balance and travel to see birds around the world – including Starlings (exotic species in Africa and Asia as well as our own familiar species!). I have long wanted to do the House Sparrow, as it has such a fascinating historical relationship with human beings, and lives closer alongside us than any other species of bird. As a result – just like the Starling – we are very ambivalent towards it.  

When we chose the Starling, we had a shortlist of three, the others being Skylark and Kingfisher; yet bizarrely, when I did an X/Twitter poll amongst 2,000 people, the vote split almost exactly to one third for each!  

I can’t do some species that readers of the series have suggested, either because, like the Blackbird and Blue Tit, they don’t have very unusual or distinctive behaviour or cultural importance; or because others have already written similar (and excellent) books – such as Sam Lee on the Nightingale and Charles Foster and Sarah Gibson on the Swift.  

Currently I am keen on either the Peregrine Falcon or the Puffin, both of which have really strong biological and cultural aspects to their lives – I’d be fascinated to hear which of these species NHBS customers – and your excellent staff – think I should choose! 

STEPHEN MOSS is a lifelong birder, broadcaster and bestselling author, whose books have appeared in almost twenty different countries. The Starling is the sixth volume in his celebrated ‘Bird Biographies’ series, following the Robin, Wren, Swallow, Swan, and Owl – and of course The Twelve Birds of Christmas, which featured the dozen species in the famous festive carol. In total these have sold over 100,000 copies, and been translated into Dutch, German and Chinese.

The NHBS Guide to Swift Nest Boxes

Alongside House Martins and Swallows, Swifts are losing suitable nesting habitat at an alarming rate. Through changes to roof design and structure, nesting sites are becoming increasingly rare. This has contributed to the widespread decline of this species which has seen them added to the UK Red list.  

Swifts return to Britain and Ireland from April, following a lengthy flight from Africa. Before leaving in August, Swifts must mate, lay and incubate their eggs. Nest boxes provide Swift colonies with the perfect site to raise their young – boxes should ideally have a large internal cavity with an elongated entrance hole, either at the bottom or downward facing. Swift nest boxes should be placed under the eaves of a building, on walls at least five metres in height. Since these birds nest in colonies, multiple nest boxes or boxes on neighboring houses are ideal for attracting more Swifts.  

Here, we look at a selection of nest boxes suitable for Swifts, highlighting the benefits of each design.  

Key materials 

Wooden nest boxes are preferred by many. This lightweight material is breathable and provides excellent insulation for nesting birds, helping to protect them from temperature extremes between seasons. Typically used for external boxes, harder wood types provide a fair level of robustness and longevity when at least 15mm thick and help to prevent predator access to the nest.  The main drawback of wooden nests is the maintenance they require – they should be monitored to ensure the wood remains in good condition, and care taken in choosing wood treatments as many can be harmful to nesting birds. 

WoodStone and Woodcrete are almost identical in composition, but Woodcrete is a patented material by Durisol. The material is made from a blend of wood and concrete to produce long-lasting, very durable boxes which can last for decades. It has good insulative properties and creates a thermally stable environment inside the box to shelter inhabitants from extreme temperatures. This material is offered for both built-in and mounted nest boxes but is more often used for built-in boxes due to its weight, which is heavier than wood or eco-plastic. WoodStone is typically more expensive than other materials and requires thoughtful design to improve ventilation to prevent the buildup of moisture in the nest.  

Certain components of a bird box may be made with eco-, or regular, plastic. A low-cost option, plastic is more lightweight than Woodcrete, and provides more longevity than wood. This weather resistant material is easy to maintain and is often sourced from recycled plastics. Nest boxes featuring eco-plastic require careful design to mitigate issues with insulation and ventilation. This material is, however, less durable and provides little resistance to predators or extreme temperatures.

The NHBS Guide: House Martin and Swallow Nest Boxes

Modern infrastructure has come with a host of changes to roof design, which have impacted the availability of suitable nesting sites for a number of avian species. House Martins and Swallows have been particularly affected by these changes, and we can encourage their colonisation, nesting and breeding through the provision of artificial habitats. 

These birds live in colonies of around five nests constructed using spring mud, but in drier springs this can be in short supply. Gathering building materials also requires significant energy expenditure for breeding birds, removing energy available for roosting and raising young. Nest boxes provide a ready–made habitat suitable for nesting without spring mud availability. 

Swallows and House Martins require a cup or bowl-shaped nest, with a small, narrow entrance and are generally made of Woodcrete/WoodStone or hard wood. They are typically placed under the external eaves of a building to mimic natural nesting locations and are best placed on a sheltered side at a minimum height of 2m above the ground. Due to their natural nesting habits, House Martin and Swallow nests are designed to be wall mounted. These birds are highly sociable and prefer to nest in colonies, so consider mounting multiple nests to further support natural behaviour. 

Here we look at a selection of nest boxes suitable for House Martins and Swallows, highlighting the benefits of each design.

Author interview with Gabriel Hartmann: Atlas of Feathers for Western Palearctic Birds, Volume 1: Introduction

This book (or rather book series, since it will be more than just one book) has been an incredibly long time in the making, and the sheer scale of the project alone makes it a huge achievement. What were the main challenges you came across and how were they overcome? 

Our project began in 1998 when the French publisher Delachaux et Niestlé requested us to create a new feather identification guide based on colour photos. The illustrations of feathers in our Atlas are arranged according to a unique, recognisable pattern on a standardised grey background, each of them depicting the feathers of an individual bird, which allows readers to grasp the essence of different feather types at a glance. We use a method of directly scanning feathers on a flatbed scanner that was developed at the University of Amsterdam. But printing costs were prohibitive. Print-on-demand technology made it possible to produce smaller, more affordable print runs. We used this technology to produce our first collective work of the Feather Research Group titled The Tail Feathers of the Birds of Central Europe. We also produced two feather calendars with a series of colour plates that were composed for our Atlas of Feathers for Western Palearctic Birds as a test run to see how the colours came out in print.     

In 2009, after 10 years of intense work, we produced a DVD with 1,280 colour plates featuring illustrations of feathers for 330 Passerine species. This compilation from many sources resulted in a wave of interest in our project. Meanwhile, the number of Passerine species for which colour plates were ready had nearly doubled to more than 600 species. We decided to publish our collective work under the name The Featherguide rather than any individual names. In this way, everyone in our group can identify with this eponym and no one needs to feel that anyone is adorning themselves with borrowed plumes.

The most time-consuming aspect of our work is the composition of feather images for bird species that are not found in any feather collections. Thanks to the kind support of the Feather Identification Laboratory at the Smithsonian Institution, and generous curators at Natural History Museums, it was possible to develop a technique that allows us to extract depictions of isolated feathers from photographs of bird skins. The missing part of the feather that remains in the skin is digitally added in a seamless way. A single colour plate produced in this way from many different puzzle pieces takes up to one week. With 1,350 bird species to be covered in our Atlas and our goal of illustrating all important plumages, you can imagine how many months and years this adds up to. We thank readers for their patience and interest.  

Our project has inspired a number of off-shoots that will be welcome by most readers. For example, the French feather identification book by Cloé Fraigneau, which is now available  under the title An Identification Guide to the Feathers of Western European Birds, emerged from the initial planning sessions we had with the director of Delachaux et Niestlé. The series of books on feather identification by Professor Hans-Heiner Bergmann was inspired by our flyer distributed at the International Ornithological Congress in 2006. A book titled Feathers: Displays of Brilliant Plumage by world–renowned photographer Robert Clark features several photographs of original feather sheets that were mounted for our Atlas of Feathers for Western Palearctic Birds, each depicted on a full double page. Even Audubon Magazine featured a series of photographs of original feather sheets from our Atlas of Feathers for Western Palearctic Birds. The Feather Atlas for North American Birds, published online by the Forensics Laboratory of the U.S. Fish and Wildlife Service, was inspired by our original project description in the Conference Proceedings of the International Bird Strike Committee. The Featherbase website, which gets several million visitors per year, adopted the same grey background colour that we had chosen for our illustrations and also adopted the idea of depicting wing and tail diagrams in the way that we presented in our original project description.

The study of feathers has an obvious application for species identification, particularly when dealing with bird remains. But can a study of feathers also provide us with an insight into bird evolution and taxonomy, or indeed other areas of research? 

Yes, indeed, much can be learned on these topics through the study of feathers. Subtle variations in the phenotype constitute the raw material for natural selection to act upon. Through the study of feathers, we can gain a deeper understanding of evolution. The high amount of phenotypic plasticity in bird wings is a clear example of evolution in progress. Many species exhibit subtle fluctuations in the extent and depth of emarginations on their primaries, resulting in different numbers of slots in their wings between different individuals. Another area of phenotypic plasticity is unusual variations in the number of flight-feathers. Our Feather Research Group compiled a large body of such variations from scientific literature and from our own research. 

While feathers were not unique to birds, emarginations are. Birds as we know them today are thought to have evolved from Mesozoic stem birds that coexisted with feathered dinosaurs. The only line that survived the cataclysmic event on Yucatan 66 million years ago evolved emarginations in their wings. If we consider birds as a class of their own, then the feature that distinguishes birds from feathered dinosaurs is the presence of emarginations. The evolution of emarginations can bring clarity into today’s scientific discussion on the origin of birds, which largely portrays birds as living dinosaurs, thereby blurring the line between reptiles and birds. Emarginations make birds unique. Neither bats nor insects nor pterosaurs have emarginations in their wings. Not all bird families living today have emarginations in their wings, giving rise to the question whether these bird families never evolved emarginations or whether their emarginations disappeared during the course of evolution. Emarginations can be lost either through the evolution of very narrow, pointed wings or through devolution into flightlessness. 

Whether our findings have any relevance for taxonomy is up to taxonomists to decide. In the past, taxonomy was entirely based on phenotype, while today it is largely based on  genotype. Phenotypic variations do not play a significant role in current taxonomy, unless one is interested in the possible inheritance of epigenetic switches that regulate the expression of the genotype into the phenotype. For example, it is not clear whether the fine-tuning of the gradient in retinoic acid that is linked to two genes on the sixth and eighth chromosomes (and is responsible for the regulation of the vane width of feathers) was already inherent in the genome of Mesozoic stem birds and was activated through one of these epigenetic switches, giving rise to emarginations in modern birds. This question may be possible to answer by looking at the genome of bird families that appear to have never evolved emarginations so far, such as rails.

Who do you think these books will appeal to and who will benefit from such a comprehensive and high-quality atlas? 

Anyone who visits the Featherbase website and finds the scans of feathers depicted there to be useful or interesting will also benefit from our work. If only 1% of the millions of visitors to this website see any value of having a printed Atlas with feather images of similar or even higher quality, this will make our  Atlas of Feathers for Western Palearctic Birds worthwhile.  

Many of the scans shown on the Featherbase website are from the collection of Dr. Wolf-Dieter Busching, the former director of the Naumann Museum in Köthen, Germany, who built up the largest scientific feather collection in the world, comprising feathers of around 2,500 bird species. During the time of the former communist regime in East Germany, it was difficult for Dr. Busching to obtain paper of a consistent colour for mounting the feathers in his collection. Therefore, his feather specimens are mounted on paper of many different colours, sometimes blue, sometimes red, sometimes yellow. Since the vanes of feathers are semi-transparent, the colour of the paper they are mounted on influences the colour of the feathers. In addition, the feathers in Dr. Busching’s collection often overlap each other, thereby hiding parts of the neighbouring feathers. In our Atlas of Feathers for Western Palearctic Birds, we show all feathers on the same standardised grey background and without overlap. In this way, each feather is fully visible and the colours of the feathers can be reliably compared.  

Of course, the production of a series of books with high-quality colour plates is more expensive than running a website. The cost of such a series in printed form will limit the number of potential buyers compared to the number of visitors to the Featherbase website. We will keep the cost as low as possible to maximise the  number of people able to afford our series in printed form.

The first volume in the series provides readers with a global overview of feather characteristics. Were there any particularly surprising data or revelations that resulted from compiling such a comprehensive collection? 

There were several surprises indeed. Two of the most peculiar discoveries, or rather rediscoveries, were made in the families Tityridae (tityras, becards and allies) and in the family Trochilidae (hummingbirds). In the families Tityridae, two genera, Tityra and Pachyramphus, have a small, crippled primary number 9 in between normally-sized neighbours in the wings of adult males, while females and juveniles have normally formed wings. The function of the reduced-sized P9  may be related to sound production (sonation) during the display of adult males, but so far, we could not find any references in the scientific literature that would substantiate such an assumption. Amazingly, this peculiar phenomenon had even escaped the attention of Dr. Wolf-Dieter Busching, who devoted his entire life to the study of feathers, and none of our other collaborators in the Feather Research Group noted this phenomenon. 

There are currently three mounted feather specimens of adult males of these two genera on the internet, one of them from the collection of Dr. Busching and two from other feather collections. In each of these three feather collections, the reduced-size P9 was mistakenly glued in front of P10 rather than in its correct position between P8 and P10, indicating that the respective feather researchers had no clue where this feather belongs and seem to have misjudged it to be a reduced outer primary, as is found in many passerines. However, when we consulted an older publication on feathers from 136 years ago, it turns out that this odd, reduced-size feather was already noted by Hans Gadow in 1888, at least in the genus Tityra, while its presence in the genus Pachyramphus seems to have escaped his attention, too.  

The second peculiar discovery in the family of hummingbirds concerns the presence of emarginations at the tips of the outer primaries in males of 22 species from five genera. Most of us in the Feather Research Group had assumed by default that none of the hummingbird species have any emarginations, based on our experience with the many species for which we had examined feathers. The great majority of the 377 extant hummingbird species do not have any emarginations, as in the related family of swifts. So, it would have been easy to miss these exceptional few species if the effort had not been made to look at every single hummingbird species based on photographs of live birds. Again, the fact that only males of these exceptional species have emarginations, while females are missing them, leads to the assumption that these emarginations have something to do with the display flight of males. In this case, there is indeed a scientific paper dating back to 1983, which confirms this assumption for just one of the 22 hummingbird species in which males have emarginations. The only feather experts who knew about this study are Professor Lukas Jenni and Dr. Raffael Winkler from Switzerland. The authors of this study found that males create noises with their emarginated primaries and that these noises are used to protect nectar resources. Filling the slot between emarginated primaries with a glue film or clipping the distal 2–3 mm of these primaries caused males to sing more to protect their territories. We can deduce that the other hummingbird species in which males have emarginations use them in a similar way to produce sound. There is, however, a sixth genus of hummingbird in which males have inverse emarginations at the base of the primaries, not at their tips. This phenomenon of emarginations at the feather bases instead of at their tips does not make any aerodynamic sense, so it is likely that these inverse emarginations have some type of ornamental function in males.  

These two discoveries, or rather rediscoveries, in the families Tityridae and Trochilidae teach us to remain open and not adhere to preconceived ideas. They also teach us to consult old literature that may have been forgotten or considered outdated.

The first volume will initially be published in black and white to make it affordable to as many people as possible. The online database of feathers is also available to everyone in the hopes that citizen scientists and members of the public will help to verify and correct the results. Given that birdwatching is such a popular pastime, do you think that there is a large body of untapped knowledge within the birding public? 

There definitely is a large body of untapped knowledge within everyone, not only within the birding community. The key is to allow everyone to express their inner potential themselves. We are in favour of encouraging birders to publish their own data under their own names. Professor Peter Finke, who advises our Feather Research Group, calls this approach of empowering citizens to publish their own data Citizen Science Proper. What has been prevalent so far is Citizen Science Light, in which so-called experts scoop off the knowledge of the public and make a name for themselves with borrowed plumes, so to speak. Professor Finke published a book titled Citizen Science: The Underestimated Knowledge of Laymen (, which answers this question in much greater depth, giving many examples for birdwatchers in particular.  

With regards to the global survey of emarginations in all bird species of the world, that became possible on the basis of photographs of live birds, which citizen scientists generously share on the internet. Our approach of opening our research findings on the number of emarginations in all bird species of the world by listing the internet links of the original photos that were used for this study is a way of thanking  these many thousands of photographers. They all deserve to be mentioned as co-authors of our study. By sharing our findings and providing the original links to the photos that were used, we offer these photographers a way to give us their feedback on what we discovered thanks to their generosity. Anyone else who likes to share their observations on the photographs of live birds and scans of feathers that were used for our study is also welcome. We greatly value this interaction with birdwatchers and the general public.

How many volumes will the series eventually comprise, and do you know when they are due to be published? 

After our last meeting in 2016, the World Feather Atlas Foundation purchased ten large scanners for our Feather Research Group. Five of these scanners went to the Featherbase team to support their endeavour of creating a World Feather Atlas. The remaining five were given to other collaborators in our group. The Featherbase team adopted the same grey background for newly mounted feather specimens as we adopted in 1998 for our Atlas of Feathers for Western Palearctic Birds. This unified the backgrounds on all scans,  creating the basis for a potential cooperation to speed up the work on our Atlas of Feathers for Western Palearctic Birds.  

The production of colour plates for the passerines took 24 years because they were all produced by only one person. If the work on the colour plates for the non-passerines is divided up by the holders of these ten scanners, it will be possible to produce the remaining colour plates more quickly. At the same time, the holders of these scanners can use them for their own projects.  

Most important to us is to respect the copyrights of everyone who produces scans of feathers. Any contributions to our Atlas of Feathers for Western Palearctic Birds must be based on mutual respect for everyone’s free will. Those who contribute scans of feathers are treated at an equal level to those who contribute text. In the past, illustrators of bird guides were often underappreciated compared to the authors. All too often, illustrators were not even mentioned on the book cover. We feel that this relationship between illustrators and authors needs to be amended. Illustrators deserve to be cited alongside authors. In our Atlas of Feathers for Western Palearctic Birds, the work of those who produce scans of feathers is even more important than those who write the texts, because the texts can only be written on the basis of these scans. 

The Full Edition of our Atlas of Feathers for Western Palearctic Birds will comprise a total of ten volumes including the introductory volume. Each of the subsequent nine volumes will cover about 150 bird species, adding up to a total of about 1,350 bird species. The Concise Edition will consist of two volumes. . The most precious thing we have to offer are the large-size colour plates in the full edition. The illustrations of feathers in the Concise Edition will be a cut-down version of the original colour plates and considerably smaller.

Author Q&A with Rob Thomas: The Storm-petrels

In the latest work of the Poyser series, Rob Thomas brings us the definitive work on Europe’s storm-petrels. Meticulously researched by one of the world leading experts, this book follows European Storm-petrels, tracking their lives as they breed, migrate and overwinter. Rob shares the story of the group’s evolution, behaviour, ecology and adaptations, interspersed with charming personal anecdotes and observations.  

Portrait of Rob Thomas facing the camera

Rob Thomas has been working at Cardiff University for over 20 years. He is a senior lecturer in Zoology who specialises in bird behaviour and ecology, and has been studying storm-petrels since he was 16. His work has taken him to Wales, Scotland, Portugal and the Faroes, where he studies storm-petrel breeding behaviour and long-distance migration journeys. He is the co-director of Eco-explore Community Interest Company and is a trustee of the Initiative for Nature Conservation Cymru (INCC). 

We recently had the opportunity to chat with Rob about what inspired him to write a book on storm-petrels, his favourite storm-petrel facts and more.

Can you tell us a little bit about yourself and what inspired you to write a book about Storm-petrels? 

I’ve been birdwatching since I was a small boy – initially in the land-locked county of Breconshire in mid-Wales where I grew up, but as a teenager I started visiting the islands of west Wales and later Shetland, where I encountered storm-petrels for the first time. Since then, I have been fascinated by these remarkable little seabirds and the islands where they breed. Birdwatching led me into bird-ringing, and later into a career as a university researcher and lecturer, and storm-petrels have been the subject of much of my research and teaching work, including supervising various MSc and PhD projects on the behaviour, ecology and conservation of different storm-petrel species around the world. In recent years there has been an explosion of storm-petrel studies, partly due to advances in miniaturised tracking technology and the genetic methods that can be used to study storm-petrel diet and evolutionary relationships. Given the mass of new discoveries being made, together with renewed interest in the folklore, art and literature relating to storm-petrels, they became the natural subject for a new book about these truly remarkable seabirds.

What do you think is the biggest challenge facing these species, and how do you think we can work to minimise the impacts of this challenge in the future?

Seabirds are among the most threatened groups of birds globally, and storm-petrels themselves are vulnerable to a wide range of threats, including various forms of pollution (e.g. plastics, oil and other chemical pollutants, as well as light pollution), overfishing, and the looming impacts of rapid climate and oceanographic changes. For storm-petrels, perhaps the greatest threat of all comes from the arrival of non-native predators on their breeding islands; rats and cats have caused the local extinction of storm-petrels on numerous islands, as well as the likely global extinction of one species, the Guadalupe Storm-petrel. Fortunately, this threat can very effectively be addressed by the eradication of non-native predators, and this is steadily being carried out on seabird islands around the world, including in the UK and British Overseas Territories such as South Georgia. This is one of the most dramatically – and immediately – effective methods for helping storm-petrels that we have in the conservation toolbox. 

 

There are often challenges with tagging storm-petrels due to their small stature. Are there any technological advances in surveying and research techniques that you would like to see employed and that would aid in tagging and monitoring them?

The miniaturisation of tracking technologies over recent years (geo-locators and GPS tags, as well as associated technologies such as accelerometers and depth-loggers) has led to a genuine revolution in our understanding of the behaviour and ecology of storm-petrels at sea. It is only in the last few years that GPS tags have become small enough to track birds as small as the smallest storm-petrels, including our own European Storm-petrel; the familiar species of the NE Atlantic (weighing approx. 25g), and we suddenly have a quite detailed understanding of where they go and what they do at sea. This tracking technology is now being deployed on some of the very rarest species (e.g. Monteiro’s storm-petrel of the Azores), to understand their conservation needs. One very exciting new development is the combination of tracking storm-petrels on their foraging trips at sea, with DNA analysis of the prey that storm-petrels deliver to their chicks, and remote-monitoring of behaviour in the nest burrow using miniaturised cameras and audio equipment – these can be used alongside more traditional methods, such as manual nest-checks and weighing of nestlings, to understand the factors on land and at sea that contribute to breeding success or failure.

I really enjoyed learning that the oldest European Storm-petrel recorded was estimated to be 40 years old, an astonishing age for such a small seabird. Do you have a favourite piece of information you discovered throughout researching and writing this book?

Yes! I have many favourite storm-petrel facts, including my provisional top five:1) storm-petrel chicks can hibernate (i.e. strategically reduce their body temperature and become torpid across multiple days) in order to save energy between food deliveries by their parents; 2) storm-petrels have the largest eggs relative to their body size (approx. 25-30% of the mother’s body mass) of any birds; 3) we still don’t know how many storm-petrel species there really are (the 28 formally-described species in the book is definitely an underestimate); 4) the New Zealand Storm-petrel was thought to be extinct for 176 years, until it was re-discovered in 2003 and happily seems to be thriving; and 5) the name ‘petrel’ may not refer to the disciple Peter walking on the waters of the Sea of Galilee as has often been stated, but may actually be derived from a much older old word ‘pet’, meaning ‘to break wind’ (yes, I am easily amused). 

 

The world is currently facing a worrying decline in not only storm-petrel populations, but also many other seabird species worldwide. What would you say to people who might question the importance of safeguarding and conserving these animals 

Most people have never heard of storm-petrels, let alone seen one. But this does not mean that storm-petrels are unimportant – they are perhaps more important that even I (a self-identifying storm-petrel fanatic) had assumed. Species do not need to be useful to humans to be an important part of the ecosystem that they inhabit; they are ecologically important in their own right, whether we are aware of them or not. Furthermore, storm-petrels reveal to us many of the ways in which our own activities as humans are impacting the natural world. Even storm-petrels, among the wildest of creatures, breeding in some of the most remote parts of our planet, are badly affected by our pollution, our entourage of non-native pets, livestock and plants, and they are highly sensitive biological indicators to the ongoing climatic and oceanographic impacts of our activities that are changing the composition of the planet’s atmosphere. For all of these reasons, it is important that we understand and act on the things that storm-petrels can tell us, or we ignore these messages at our peril.

Is there a species of storm-petrel that has so far eluded you, and which you would still love to see? 

Oh yes, there are many! I have personally encountered only six or seven of the 28 or so storm-petrel species that are currently available (depending on how species are counted). I am hoping to spend the rest of my life occasionally meeting new storm-petrel species; two of my most-longed-for are the White-vented Storm-petrel (probably the smallest seabird in the world), and the Matsudaira’s Storm-petrel (one of the least-known and most-endangered of the storm-petrel species). 

 

Finally, are you currently working on any other projects that you can tell us about?

Yes, an exciting new project involves working with local conservationists on the Faroe Islands (which host the largest colonies of European Storm-petrels) to understand the impacts (both positive and negative) of marine developments such as wind farms, fish farms and artificial lighting on these internationally important breeding colonies. Another very exciting new initiative is a collaborative project known as ‘Seaghosts’, led by Raül Ramos Garcia of the University of Barcelona in Spain, tracking the movements of different species of storm-petrels from breeding colonies across the North Atlantic, across their annual cycles. Seabirds ignore national boundaries, and such international collaborative projects are key to understanding threats and conservation solutions at a global scale.

How to Choose a Pair of Binoculars

A good pair of binoculars is an invaluable part of any field kit and they provide some of the most memorable wildlife encounters. There is an overwhelming array of sizes and specifications and it can be difficult to choose between them when purchasing a new pair. In this post we will provide a summary of some of the key features of a pair of binoculars, to help you find the best pair to accompany you on surveys, whilst travelling or when enjoying your local wildlife.

Once you have decided on your budget, there are a few key metrics that will help you decide which pair of binoculars will suit you best. With binoculars it really is worth paying as much as you can afford as the glass, lens coatings and specifications improve with every step up in price.

Magnification

Binocular models generally have two numbers in their description. The first of these relates to the magnification. (For example, 8 x 42 binoculars will have a magnification of 8x). In general, binoculars have a magnification between 8x and 12x. As you would expect, the higher the magnification, the larger objects will appear when looking through them. As magnification increases, the field of view can be reduced and you will need to ensure that you have steady hands or use some kind of support.

Lens Diameter

The second number in the binocular model description (e.g. 8 x 42) refers to the diameter of the objective lens. Standard size binoculars tend to have objective lenses of 32mm to 42mm whilst lenses in compact binoculars usually measure 25mm. Larger lenses can dramatically improve low light performance and are particularly good for use at dusk or dawn. The trade-off is that larger lenses are heavier. The most popular size of binoculars for birdwatching was traditionally 8 x 42, but with advances in manufacture and lens performance, 8 x 32 binoculars now offer fantastic specifications in a more compact body.

Glass Type

The type and quality of glass have a huge impact on image quality. Image by Bicanski via Public Domain Images

The type of glass used to manufacture the lenses can vastly affect the quality of the image. Two types of glass to look out for are extra-low dispersion (ED) and fluoride (FL) glass. These reduce chromatic aberrations giving clearer and sharper colours and reduced colour “fringing”.

 

Fringing is the blurring that can occur between light and dark parts of an image. If your budget allows for an upgrade to ED glass binoculars, you will notice a distinct improvement in clarity compared to binoculars without ED glass. Affordable pairs of ED binoculars include the Hawke Optics Endurance ED and the Opticron Explorer ED.

Lens and Prism Coatings

The primary difference in performance and the brightness of images between different pairs of binoculars is often due to lens and prism coatings. Light is lost as it travels across every surface inside a pair of binoculars and the aim of a good pair of binoculars is to keep light transmission as high as possible between the objective and the ocular lens. Lens and prism coatings reduce the amount of light that is lost helping to produce a brighter and sharper image. Lenses that are multi-coated have multiple layers of lens coatings. High-quality binoculars are fully multi-coated which means that they have multiple layers of coating on all lens surfaces. Roof prism binoculars have a particular problem with “phase shift” where the polarisation angle of the prism causes the light passing through to be split into two slightly out of phase beams. This results in an image that has lower resolution and may look slightly blurred. Prism coatings correct this problem by forcing the split light back into phase. Look out for binoculars with Phase Correction (PC) prism coatings.

Key Comparison Metrics

Comparing some of the performance metrics of a pair of binoculars can help when deciding which pair would best suit your purposes. In particular, field of view will be useful if you are looking at large landscapes (e.g. whale or sea watching) and close focus is very important if you are looking at insects.

Field of View – The field of view is how wide an image can be seen at a specified distance (usually 1000m). A wide field of view is useful for large landscapes and for fast-moving animals. Models with a particularly wide field of view include all of the Kite Optics range, the Opticron Discovery, Traveller ED and Explorer ranges, the Bushnell Prime and Forge ranges and the Swarovski EL and SLC binoculars.

The Opticron Discovery range of binoculars has a fantastic field of view and great close focus.

Close Focus – The close focus is the minimum distance at which the binoculars are able to focus. People interested in viewing insects using their binoculars would be advised to choose a model with a small close focus distance. Models with particularly low close focus include the Opticron Discovery and Traveller ranges, the Swarovski EL and the Kite Lynx HD+ binoculars.

Weight – The weight of the binoculars is incredibly important, as it is likely that you will be carrying them around for long periods of time. Higher quality models of comparable specification will tend to be lighter than entry-level models, and those with larger objective lenses will weigh more than those with smaller ones. Binoculars that are particularly lightweight and excellent for travelling include the Opticron Traveller range and the Hawke Optics Nature-Trek and Endurance ranges.

Eye Relief – This is the maximum distance from the eyepiece lens that the eye can be positioned at which the full width of the image is visible without vignetting (darkening of the image around the edges). Longer eye relief is useful for those who wear glasses.
