The NHBS Guide to UK Marine Mammal Identification

Marine mammals, including seals and dolphins, are generally well-loved and charismatic species. Some people may be surprised by the variety of marine mammals we are lucky enough to have living around and visiting our coasts.

In this guide we will summarise a number of the marine mammal species you are most likely to spot in UK waters, and how to identify them. Identifying marine mammals can be a rather challenging task as often only a bobbing head or fin is visible, but knowing what features to look out for can sometimes be enough to make a fairly confident identification.

It is very important to note that seals and cetaceans are legally protected in the UK and all efforts should be made not to cause disturbance. It is strongly recommended that you do not approach marine mammals in person or by boat – any interactions should be fully on their terms.

Seals (Pinnipeds)

Two species of seal make our coasts their home: the common and grey seals. Both species are members of the family Phocidae, the true seals. Unlike other pinnipeds, such as sea lions, the true seals lack external ear flaps hence their other name, the earless seals.

Common Seal – Phoca vitulina

Common seal by Caroline Granycome (left – image cropped) and by Mike Prince (right – image cropped) via Flickr

Also known as harbour seals due to their common presence in these locations.

Appearance: Rather cat-like in appearance, with a relatively shorter snout than the grey seal and a more concave forehead. Their nostrils are closer together than the grey, creating a ‘V-shape’. Often the pelage (coat) is grey and speckled. Both males and females of this species look similar.

Behaviour: When on land, the common seal can be seen to lay on its side and hold its tail and head in the air forming a banana-like shape. They tend to be found in smaller aggregations on land than grey seals, leaving more space between individuals.

Where are they seen? Despite their name, common seals are seen less frequently than grey seals, with their population numbers less than half that of the grey. Abundant in northern England and Scotland, but rarely seen in the south. Generally seen coastally, or hauled out on rocks and beaches.

Grey Seal – Halichoerus grypus

Grey seal female (left) and male (right) by Ian Watson-Loyd

The grey seal is the most common seal species in the UK, and the UK population makes up roughly 40% of the global population.

Appearance: Grey seals have a ‘blotchy’ pelage and tend to be darker than common seals. They are also larger in size, have a more prominent snout and their nostrils are separate and roughly parallel. Female grey seals can be more difficult to separate from the common seal as they do not have such a striking snout.

Behaviour: Rather gregarious seals, they often haul out in large colonies during the breeding and moulting season. Grey seals are generally curious and on occasion will approach a boat or humans in the water to investigate (see note about disturbance, any interactions should be on the animal’s terms).

Where are they seen? Common around the UK, particularly along the western coast, Scotland and Norfolk. Generally seen coastally, or hauled out on rocks and beaches.

Dolphins and Whales (Cetaceans)

At least 25 species of cetacean have been spotted in UK waters, although significantly fewer are regularly seen. Some species are resident year-round while others simply pass through seasonally. All cetaceans, including porpoises and dolphins, are technically whales, although commonly only the larger species are referred to by this name. They are split into two groups: the toothed whales that actively hunt prey and the larger baleen whales, that use sheets of keratin (baleen) to filter feed.

Toothed whales (Odontocetes)

Harbour porpoise – Phocoena phocoena

Harbour porpoise by Ian Watson-Loyd (left) and Ben Porter (right – image cropped)

Also known as the common porpoise. The name porpoise is derived from ‘porcus’, the Latin word for ‘pig’. Colloquially they are sometimes referred to as the ‘puffing pig’ due to the characteristic ‘chuff’ made when surfacing.

Appearance: The smallest cetacean in the UK, not exceeding a length of 1.5 metres. Their dorsal fin is small and triangular and their head is rounded at the front, lacking a clear beak.

Behaviour: Generally seen as individuals or in small groups with 2-5 members. They often surface three or four times before disappearing for a longer dive. Elusive and unlikely to approach boats.

Where are they seen? Seen nationwide in shallow, coastal waters.

Common dolphin – Delphinus delphis

Common dolphin and calf (left) by Gemma Haggar and Common dolphin by Gregory Smith (right – image cropped) via Flickr

Appearance: A sleek and agile dolphin with an elongated beak and sickle-shaped dorsal fin. Easily identified by their cream and white ‘hourglass’ colouration.

Behaviour: Acrobatic and generally inquisitive dolphins. Common dolphins are frequently seen bow-riding alongside boats and leaping from the water. On occasion, groups join together to form a super-pod of hundreds of individuals. If a group of cetaceans this large is spotted in UK waters, it is almost certainly common dolphins!

Where are they seen? They tend to spend most of their time offshore in deeper waters, so are more likely to be seen by boat rather than from the shore.

Bottlenose dolphin – Tursiops truncatus

Bottlenose dolphin by Caroline Legg via Flickr (left – image cropped) and dorsal (right) by Ian Watson-Loyd

Appearance: A large, muscular dolphin with fairly uniform grey colouration. British bottlenose dolphins are the largest in the world, presumably to allow them to cope with our colder waters.

Behaviour: Travel and feed in small-medium pods, although lone animals have been seen around the UK.

Where are they seen? Bottlenose dolphins can be spotted all around our coasts if you are lucky, but are most likely to be seen in the Moray Firth, Cardigan Bay and Cornwall, where resident pods reside.

Risso’s dolphin – Grampus griseus

Group of Risso’s dolphins by ‘National Marine Sanctuaries’ (left – image cropped) and Risso mother and calf by Adam Searcy (right – image cropped) from Flickr

Appearance: Unmistakable dolphins with distinct colouration except as calves. Risso’s begin their lives dark grey but become paler and scarred with age. These marks occur from social interactions with other Risso’s and during predation events, such as with squid.

Behaviour: Studies show Risso’s dolphins to be social animals that remain in long-established pods. They are fairly active at the surface of the water and can be seen ‘spy-hopping’ – holding themselves vertically in the water with only their heads bobbing above the surface.

Where are they seen? In deeper, offshore waters. Generally spotted along the west coast of Scotland and around the Isle of Man.

Orca – Orcinus orca

Orca (left – image cropped) by Glenn Brunette via Flickr and right by Gemma Haggar

Appearance: Striking and characteristic large black cetaceans with white eye and saddle (behind dorsal fin) patches. Male orcas have the largest dorsal fin of any species at up to 6ft, significantly taller than the female orcas.

Behaviour: Orcas are very social animals that remain with their maternal pod. Different groups display different feeding strategies, tending to focus on either smaller marine mammals or fish. Orcas are fairly active at the surface and can be seen spy-hopping or tail-slapping the water.

Where are they seen? The UK’s only resident pod (8 individuals) tends to be seen on the West coast of Scotland but were spotted roaming as far south as Cornwall in early 2021. Further transient groups appear in the summer but are generally limited to northern Scotland, Orkney and Shetland.

Baleen whales (Mysticetes)

Minke Whale – Balaenoptera acutorostrata

Minke whale by Vaughn Mullen (left – image cropped) and Oregon State University (right – image cropped) via Flickr

Appearance: The smallest baleen whale seen in the UK at around 9 metres in length when fully grown. A dark grey whale with a white underside with a sickle-shaped dorsal fin located roughly two-thirds along the back. If you’re lucky enough to spot the pectoral (side) fins, the white ‘armbands’ will confidently identify this species.

Behaviour: Generally seen alone or in small groups. Minke can be seen to lunge feed at the surface, side-lunging with open mouths to take in large quantities of water and therefore prey. From afar, aggregations of seabirds can be the first hint of such a feeding event.

Where are they seen? Minke are the most commonly spotted baleen whale and can be seen nationwide. Sightings are significantly higher around Scotland and the south-west.

Fin Whale – Balaenoptera physalus

Fin whale by Charlie Jackson (image cropped) via Flickr

Appearance: The second largest whale in the world, reaching up to 24 metres in the northern hemisphere. Very dark colouration on the upper body, with the dorsal fin placed far back on the back. The fin whale has an asymmetrically coloured lower jaw, with bright white only present on the right-hand side (as shown in the above image).

Behaviour: Seen on their own, or in small groups of up to 7 individuals. When diving their tail does not rise above the surface, unlike some other large whales.

Where are they seen? Rare in UK waters, but most likely to be seen around northern Scotland and the Hebrides, although sightings have occurred off Cornwall and Ireland in recent years.

Climate Challenges: 1. Insect Decline

In the lead up to the 26th UN Climate Change Conference of the Parties (COP26) in November of this year, we are writing a series of articles looking at some of the toughest global climate crisis challenges that we are currently facing. This post looks at the evidence for and challenges posed by a global decline in insects.

What is the evidence for a global insect armageddon?

One of the first meta-analyses of insect population decline was published in 2014 by Dirzo et al. in Science under the title ‘Defaunation in the Anthropocene’. This seminal paper reported that 67% of monitored invertebrate populations showed 45% mean abundance decline and warned that ‘such animal declines will cascade onto ecosystem functioning and human well-being’. Three years later, Hallmann et al. (2017) published the results from 27 years of malaise trap monitoring in 63 natural protection areas in Germany, and concluded that insect biomass had declined by more than 75% during this time. This paper in particular was widely reported in the media, creating widespread concern among the public of an impending insect armageddon, or ‘insectageddon’.

Since then, several other reports have continued to draw attention to declines in insect abundance, biomass and diversity around the world (for excellent reviews see Wagner (2020) and Sánchez-Bayo & Wyckhuys (2019)). However, many of these studies have been restricted to well-populated areas of the US and Europe and there is little information available to assess how these patterns compare with other less well studied regions.

Despite the abundance of data suggesting a pattern of global insect decline, many studies show conflicting results, with datasets from a similar area often reporting different patterns. There is also evidence that some insects are faring well, particularly in temperate areas which are now experiencing milder winters. Species that benefit from an association with humans, such as the European honeybee, may also be experiencing an advantage, along with certain freshwater insects that have benefited from efforts to reduce pollution in inland water bodies.

What are the challenges in assessing and predicting insect population trends?

In comparison to vertebrate groups, comprehensive long-term datasets are rare for invertebrates. This is primarily down to the fact that invertebrates are incredibly species rich and so, even for those that have been formally identified and described, a considerable amount of skill and knowledge is required for reliable identification. In addition to this high level of expertise is the need for large amounts of field equipment, which means that long-term, comprehensive studies can be expensive and difficult to fund.

Both historical and current invertebrate monitoring data tends to come from a small number of wealthy and well-populated countries (usually the US and western Europe), and there are comparatively few datasets available from tropical and less developed areas. Unfortunately, these understudied countries and regions tend to be the areas where we might expect to find the most diverse and species rich populations of invertebrates.

Other challenges relate to the way that data is collected. Using total insect biomass as a measure provides a useful large-scale perspective and provides information relevant to ecosystem function. It also minimises the problems involved with taxonomy and identification. However, using this measure means that species-level trends are completely overlooked.

What are the main stressors affecting insect populations globally?

Studies suggest that the main stressors impacting invertebrates are changes in land-use (particularly deforestation), climate change, agriculture, introduced and invasive species, and increased nitrification and pollution. However, it is rare that a single factor is found to be responsible for monitored declines and the situation has been described as being akin to ‘death by a thousand cuts’.

In a recent special edition of PNAS, that looked in depth at the available research and literature on insect decline in the Anthropocene, climate change, habitat loss/degradation and agriculture emerged as the three most important stressors.

Where do we go from here?

Traditionally, conservation has focused on rare and endangered species. However, with mass extinctions and large scale invertebrate loss, which include declines in formerly abundant species, a different approach is required. Invertebrates form an important link between primary producers and the rest of the food chain, and play a key role in most ecosystems. They provide numerous ecosystem services such as pollination, weed and pest control, decomposition, soil formation and water purification, and so their fate is of both environmental and economic importance.

There are several things to be positive about within the realms of invertebrate conservation: over the past decade, funding to support insect conservation has been growing and, in many countries, there are now substantial grants allocated to monitoring and mitigation projects. The EU and US have seen widescale banning of certain pesticides following research demonstrating their impacts on both economically important pollinators and other fauna. Finally, citizen science projects to study invertebrate populations are becoming both numerous and successful, greatly increasing the amount of comprehensive, long-term data that is available to inform conservation decisions.

Despite this, much more long-term data on invertebrate populations is required, particularly from regions outside of Europe and the US, such as tropical areas of the Americas, Africa and Asia. Attention to factors such as the standardisation of survey techniques and improved data storage and accessibility are also important, as well as the utilisation of new methods including automated sampling/counting equipment and molecular techniques. Using the information available, evidence-based plans for mitigating and reversing declines are desperately required.

All of this takes time however, and we need to act now. Even without comprehensive species-level data, we know that a biodiversity crisis is occurring at a rate serious enough for it to have been termed the ‘6th Mass Extinction’. Individual, group, nationwide and global action will all be required to combat this. Widescale change in societal attitudes to insects will undoubtedly need to play a role in this process, alongside global efforts to slow climate change and develop insect-friendly methods of agriculture.

Summary

• Numerous studies have reported large-scale declines in insect populations, with several estimating a loss of approximately 1–2% of species each year.
• The availability of high-quality and long-term datasets is a limiting factor in assessing population trends. Furthermore, available data tends to be from well-populated and historically wealthy areas such as the US and western Europe, with the diverse and species-rich tropics severely under-researched.
• The main stressors thought to be impacting insect populations globally are climate change, habitat loss/degradation and agriculture. In most, if not all of these cases, a combination of these and other factors are likely to play a role.
• Although there are some aspects of insect conservation to be positive about, much work still needs to be done. Further monitoring and recording are required, particularly in poorly studies areas, in order to inform conservation decisions. Simultaneously, local and global efforts must be made to slow climate change, halt the destruction of ecologically important habitats and develop nature-compatible methods of agriculture.

NHBS In the Field – The Anabat Scout product review

Here we review the Anabat Scout from Titley Scientific. The Scout is an easy to use active bat detector that offers excellent quality live audio and recording, plus many handy surveying features and durability that sets it apart from other detectors. It uses heterodyne, auto-heterodyne and frequency division audio that can be recorded in either full spectrum or zero crossing files.

Designed with professional surveyors as well as the more serious bat enthusiast in mind, the Scout is an ideal detector to take on bat emergence and transect surveys. This is thanks to great features such as a bat counter and GPS tracking transect mode.

How we tested

In early July 2021, we tested the Scout outside an old barn in South Devon to monitor the dusk emergence of several bat species. The building was known to host many common pipistrelles, brown long-eared, lesser horseshoes and some myotis species. We wanted to see how easy the detector was to use in the setting of a busy emergence and get a feel for its recording quality and its special features. The audio was set to auto-heterodyne to see how good this feature would be with multiple bats close by. Under the trigger settings is the option to adjust the sensitivity, which we set to high as there was unlikely to be too much undesired noise in this setting.

What we found

Firstly, it is worth noting just how lightweight (at 160 grams without batteries) and easy to hold the Scout is with its handy wrist lanyard and comfortable fit within your hand. These features are particularly important when undertaking long surveys and holding other equipment such as a clipboard for instance.

The OLED display screen is small, but bright, so key information such as peak frequency and time is easy to note in the dark. With just key information visible, the screen does not become too “busy” unlike some detectors, which in some circumstances is a real advantage as it avoids too much distraction. The buttons all glow in the dark, which we found very useful once it had become completely dark, as it kept navigation simple, without having to use a torch.

One of the Scout’s most handy features are the in/out bat counter buttons which enable you to easily tally the number of bats recorded coming out and back into a roost, without the need to look away to make notes and perhaps miss bats. The counter also time and date stamps and geotags each count (CSV file output), so saves you having to manually note this data.

The Scout has a transect mode which notes a GPS coordinate every second so maps out your route as you walk it. It also logs another GPS coordinate for every bat recording made which produces detailed transect maps.

We found that the adjustable volume control was very good and loud enough when needing to compensate for background noises such as a passing lorry.

Also noteworthy was the Scout’s ability to record voice notes. Once it has become fully dark or if you are surveying and need to keep your eyes fixed on bat watching, then the ease of just speaking into the device to add survey notes or further information is very helpful.

The Scout was very productive at picking up all the bats we encountered during the evening (although sometimes a brown long-eared emerged without calling and was missed). The auto-heterodyne tuning to the peak frequency was superb and saved much time. On a few occasions, we switched to manual heterodyne which enables you to adjust the frequency by moving the up and down arrows. This setting would be useful when first teaching beginners. The Scout’s range is also excellent, which was demonstrated when a high flying noctule was picked up probably over 30 – 40 meters away.

Two recordings taken on the Anabat Scout and visualised through the Anabat Insight Software.

The recordings were always clear through the built-in speaker, although there is also the option to attach a 3.5mm headphone jack. All recordings come with GPX track files attached. This gives accurate GPS data, that when viewed on the free software: Anabat Insight, a .KML (Keyhole Markup Language) file can be generated using Google Earth which will show your route with location tags for each bat recording.

All recordings were stored on an SD Card (recommended min: 32GB and max 512GB) and then output via WAV (Full spectrum) and Anabat sequence files (Zero Crossing).

Battery life lasted roughly 10 hours on 2 x AA (NiMh, Alkaline or Lithium) batteries with the remaining memory space and battery life displayed on screen, so we could keep a check during the evening.

Our Opinion

The Anabat Scout is certainly one of the easier to use, professional bat detectors available. It is highly accurate with its triggers and by being so lightweight and practical it makes for an ideal choice for both ecological surveyors and keen naturalists alike. The Scout has been designed with the needs of surveyors in mind and even those new to bat detecting, will find it simple to use and highly rewarding.

The main limitation found was that the Scout does not display full spectrograms like the Anabat Walkabout, therefore beginners particularly, may not find this detector so helpful for learning the differences in calls and identification in the field.

Overall, we feel the Scout offers very good value as an active detector that will fulfill the needs of most ecological surveyors. Its advantage of being incredibly easy to use and get to know, makes it fantastic for beginners, subcontractors and educational purposes also.

The Anabat Scout can be found here. Our full range of active bat detectors can be found here.

Author Interview with David M. Wilkinson: Ecology and Natural History

Many books in the Collins New Naturalist Library are underpinned by ecology, but the latest addition to the series is the first to be devoted to the science in its own right. In Ecology and Natural History, David Wilkinson provides an insightful and highly accessible account of the core ecological concepts and brings them to life with examples of classic research sites and studies from across Britain.

David Wilkinson is Visiting Professor in Ecology in the School of Life Sciences at the University of Lincoln and Honorary Research Fellow in Archaeology at the University of Nottingham. He has wide interests in ecology, and in recent years has written articles for British Wildlife on such varied subjects as scent-based mimicry in wild plants and animals, lichens as composite organisms, and autumnal colour change in leaves. Here, David has kindly answered some of our questions about his new book.

Ecology is a complex discipline, encompassing all the amazingly diverse ways in which living organisms interact with one another and with their environment. What drew you to ecology as a topic for your book, and how did you set about tackling such a wide-ranging subject?

As you say ‘Ecology is a complex discipline, encompassing all the amazingly diverse way living organisms interact with one another and their environment’ – with a topic as grand as this why would you write a book on anything else! Both of my previous books (for Oxford University Press) had been on aspects of ecology, but written for a more technical audience. Having walked away from my academic day job I now felt I had the time to try and write something more accessible, but still scientifically accurate. Most of the most pressing global problems are related to ecology, so there is an obvious need for as many people as possible to have some idea of basic ecological concepts. The approach grew out of over a quarter of a century’s experience of introducing the basic ideas of ecology to undergraduates.

Chapters are split by topic but also by location, each one beginning with a scene from the site of a classic ecological study. What inspired this approach?

It seemed the obvious approach, as although this is a book on ideas I wanted to embed them in what you see in the field. The first chapter I wrote was chapter 2 which made a lot of use of Cwm Idwal in Snowdonia. Jonathan Silvertown (plant ecologist and science writer) was the member of the New Naturalist editorial board who oversaw my book. He liked the site based approach and encouraged me to use it throughout the book (his own popular book on plant diversity ‘Demons in Eden’ had used a similar approach). In many ways the approach grew out of my tendency to ‘tell stories’ when talking about ecology to beginning undergraduates. So in part the book is my lecturing style turned to prose.

Were you familiar with your chosen locations before embarking on writing, or did you make trips as part of your research for the book?

Most of the locations I used to open chapters were sites I was familiar with, but the two exceptions were Downe Bank and the Isle of Cumbrae – writing the book provided a great excuse to visit both of these. Most of the sites were visited on one or more occasion during the three years I worked on the book – the exceptions were Selborne (which I had visited a couple of years before I started writing) and Rothamsted, where the description is based on a visit in 2005. A highlight of the writing was a week’s fieldwork in the Cairngorms, taking photos for the book.

Smaller life forms such as bacteria and protists feature prominently in various chapters. How important are these organisms in helping us to understand the structure and function of ecosystems?

A key theme of the book is the importance of such organisms. Considered from a genetic or biochemical perspective most of the diversity of life on Earth is microbial. Considered from a geological perspective for most of the history of life on Earth all ecology was microbial ecology, as microbes were the only life forms around. In ecological systems today they are still crucial. Many people vaguely realise that they have some importance in decomposition and nutrient cycling, but also much of photosynthesis (and related oxygen production) is by microbes rather than larger plants. Historically microbes have been hard to study in the wild, being by definition too small to see without microscopy. However, molecular methods (using DNA or RNA) are making things much more tractable, and now microbial ecology looks poised to be one of the big growth areas in ecological research.

You were able to draw on a number of examples of high-profile and long-running experiments from British sites. How influential have studies in Britain been for ecology as a science?

Ecology has a long history but really starts to take off as a science in the early 20th century. It started to develop earlier in Britain than in most countries, indeed the British Ecological Society (founded in 1913) was the first such society anywhere in the world. Because of this several of the key early studies that helped develop the basic ideas of ecology took place in Britain.

A number of the experiments described were initiated in the early/mid-20th century. Has there been a decrease in the creation of new long-term studies in recent decades and, if so, what are the implications for conservation and ecology?

Because of the relatively early start of academic ecology in Britain the country has a number of very long running ecology field experiments. For example two I write about in the book are The Park Grass experiment at Rothamsted (started 1856) and the Godwin Plots at Wicken Fen (started 1927). Neither was started with the idea that they would run for 100 years or more – there is a large element of chance in their long-term survival. However, once an experiment has been running for a long time then people start to realise that such long runs of data are important and try and find the resources to continue them. More recent examples include (amongst many) the Buxton Climate Change Impacts Lab (which commenced in 1993 on limestone grassland in the Peak District) and grazing experiments set up in the Ainsdale Dunes system in Merseyside (started in 1974). But to be really long term requires luck and/or a succession of people determined enough to keep them going against the odds.

Finally, could you tell us about your plans for the future? Do you have any more writing projects lined up?

I have quite a list of books that would be interesting to write. The one I am most keen to do next is envisaged as a series of linked essays on ecology, evolution and the environment, as I would like to do an accessible general book that uses examples from around the world (rather than having the British focus of a New Naturalist). While I have an outline of the idea it’s in very early stages and I haven’t yet found a publisher for it. More long term another book that requires the extensive fieldwork that went in to the New Naturalist would provide a good excuse to not get trapped at a computer. I also have several ongoing ecological research projects.

Author interview with Beat Wermelinger: Forest Insects in Europe

Forest Insects in Europe has been written not only with professional entomologists in mind, but also for nature lovers generally. The descriptions of the various roles insects play in forest ecosystems are intended to be easily comprehensible, but still scientific.

We recently caught up with the book’s author, Beat Wermelinger, who works as a Senior Scientist at the Swiss Federal Research Institute WSL. His research interests include bark beetles and natural enemies, Biodiversity, windthrow succession, climate change and neozoa. Beat answered our questions in German and our bi-lingual team members were excited to translate these to English for us. Discover more below in both languages.

1) Could you tell us a little bit about your background and how you came to write Forest Insects in Europe: Diversity, Functions and Importance?

I have been working at the Swiss Federal Research Institute WSL (Swiss Federal Institute WSL) (a forest research institute) for 30 years and until recently was the head of the entomology group. Simultaneously, I have also been teaching forest insects at the ETH Zurich. During this time, a large pool of knowledge and information has accumulated. I have also been a passionate insect photographer for just as long, which is reflected in an image database of around 16.000 insect photos. These two strands provided an ideal basis for conveying the importance and fascination of insects in one scientifically based book, which was also richly illustrated with photos, for both specialists and all those interested in nature.

Können Sie uns etwas über Ihren Hintergrund erzählen und wie Sie dazu kamen, Forest Insects in Europe: Diversity, Functions and Importance zu schreiben?

Seit 30 Jahren arbeite ich an der Eidgenössischen Forschungsanstalt WSL (Swiss Federal Institute WSL) (einem Waldforschungsinstitut) und leitete dort bis vor kurzem die Gruppe Entomologie. Zugleich unterrichte ich fast gleich lang zu Waldinsekten an der Hochschule ETH in Zürich. In dieser Zeit hat sich ein grosser Fundus an Kenntnissen und Informationen angesammelt. Ausserdem bin ich seit mindestens ebenso langer Zeit ein passionierter Insektenfotograf, was sich in einer Bilddatenbank von rund 16.000 Insektenbildern niedergeschlagen hat. Diese beiden Grundlagen boten eine ideale Basis, die Bedeutung und Faszination von Insekten in einem zwar wissenschaftlich fundierten, aber auch reich mit Fotos illustrierten Buch sowohl Fachpersonen als auch allen Naturinteressierten zu vermitteln.

2) The book tackles a vast array of insect groups and ecological functions – were there any particular challenges in collating so much information in one place?

Much of the information comes from my readings or lectures. However, since I wanted to portray the ecological and economic importance of forest insects as broadly as possible, I still had to review a lot of published material. Above all, I wanted to support quantitative data with accurate citations. Owing to the Internet, such research is easier today than it was 20 years ago… Fortunately, I also had my own photographs on almost all topics.

Das Buch befasst sich mit einer Vielzahl von Insektengruppen und Funktionen – gab es besondere Herausforderungen, so viele Informationen in einem Buch zusammenzufassen?

Ein wesentlicher Teil der Informationen stammt aus meinen Vorlesungen oder Vorträgen. Da ich aber die ökologische und ökonomische Bedeutung von Waldinsekten möglichst breit darstellen wollte, musste ich doch noch Einiges an Literaturarbeit leisten. Vor allem wollte ich quantitative Angaben mit korrekten Literaturzitaten abstützen. Dank dem Internet sind solche Recherchen heute einfacher als noch vor 20 Jahren… Erfreulicherweise hatte ich auch zu fast allen Themen eigene Bilder.

3) Are there any insect groups that hold a particular interest for you?

Professionally, I am mainly concerned with wood-dwelling insects. I am especially interested in the bark beetles, and their natural enemies as well as the intensive interactions with their host trees. Bark beetles are known to be pests, but they are also pioneers in the decay of wood. I also deal with the wood-dwelling longhorn beetles and jewel beetles, which often lend themselves to photography because of their size and beauty. For decades I have dealt with the development of their biodiversity after disruptive events such as storms or fire. The social red wood ants or the galling insects also fascinate me with their ingenious way of life.

Haben Sie eine Insektengruppe, an der Sie besonders interessiert sind?

Beruflich beschäftige ich mich vor allem mit holzbewohnenden Insekten. Mich interessieren die Borkenkäfer, ihre natürlichen Feinde und die intensiven Wechselwirkungen mit ihren Wirtsbäumen. Borkenkäfer sind zwar als Schädlinge bekannt, sie sind aber auch Pioniere beim Holzabbau. Weiter befasse ich mich mit den holzbewohnenden Bock- und Prachtkäfern (longhorn beetles, jewel beetles), die sich oft ihrer Grösse und Schönheit wegen auch zum Fotografieren anbieten. Über Jahrzehnte habe ich mich mit der Entwicklung ihrer Artenvielfalt nach Störungsereignissen wie Sturm oder Feuer beschäftigt. Auch die staatenbildenden Waldameisen (red wood ants) oder die gallbildenden Insekten (galling insects) faszinieren mich durch ihre ausgeklügelte Lebensweise.

4) In Chapter 18, you discuss the severe and widespread decline of several insect groups. What has caused so many species to dwindle in European forests? And what is being done to address these threats?

There are two main causes for the decline in much of the forest insect fauna. The intensive use of wood in the past centuries has led to the fact that the forest area in Europe has decreased significantly over a long period of time, the trees no longer reach their natural age phase, and there were almost no dead trees that could slowly rot. In the case of many wood-dwelling insects that are dependent on so-called habitat trees or develop in decayed, thick tree trunks, this has led to a severe threat to their biodiversity. In recent decades, the forest area has increased again and in many countries the preservation of old trees and dead wood is being promoted. However, the impact is still modest.

A second reason is the fact that many shrubs and pioneer tree species such as willow and poplar have disappeared and the forests have often become more monotonous and closed. This mainly affects the forest butterflies. Today, clearings are created on purpose from which not only these insects, but also other light-loving forest species such as certain orchids or birds can benefit.

In Kapitel 18, erwähnen Sie den verbreiteten Rückgang mehrerer Insektengruppen. Was hat den Rückgang so vieler Arten in den europäischen Wäldern verursacht? Und was wird getan, um diese Bedrohungen zu begegnen?

Es gibt hauptsächlich zwei Gründe für den Rückgang eines grossen Teils der Waldinsektenfauna. Die intensive Holznutzung der vergangenen Jahrhunderte hat dazu geführt, dass die Waldfläche in Europa über lange Zeit sehr stark abgenommen hat, die Bäume nicht mehr ihre natürliche Altersphase erreichten, und fast keine abgestorbenen Bäume vorhanden waren, die langsam verrotten konnten. Dies hat bei vielen holzbewohnenden Insekten, die auf sogenannte Habitatbäume angewiesen sind oder sich in toten, dicken Baumstämmen entwickeln, zu einer starken Bedrohung ihrer Artenvielfalt geführt. In den letzten Jahrzehnten hat die Waldfläche zwar wieder zugenommen und in vielen Ländern wird der Erhalt von alten Bäumen und Totholz gefördert. Die Auswirkungen sind jedoch noch bescheiden.

Ein zweiter Grund ist die Tatsache, dass durch die Bewirtschaftung viele Sträucher und Pionierbaumarten wie Weiden oder Pappeln verschwanden und die Wälder oft monotoner und dunkler geworden sind. Dies wirkt sich vor allem auf die Wald-Tagfalter (forest butterflies) aus. Heute werden gezielte Auflichtungen durchgeführt, von denen nicht nur diese Insekten, sondern auch andere lichtliebende Waldarten wie bestimmte Orchideen oder Vögel profitieren.

5) A particular highlight of the book is the wonderful collection of insect photographs, most taken by you. Do you have any advice for people interested in insect photography?

The main problem when photographing small objects is always to be able to focus as much as possible on them. This requires a small aperture and therefore a lot of light. I photograph everything “hand-held” and therefore the shutter speed should be short. For these reasons, I almost always use a ring flash with separately controllable halves and 100 mm macro lens with my SLR camera. Nonetheless, even cameras with a small sensor (even mobile phones!) can nowadays produce surprisingly good images of larger, less volatile insects.

In order to photograph an insect as sharply as possible, you should position yourself so that the insect is parallel to the camera. At least the eyes should always be sharp. Of course, you can also choose a different level of focus for special effects.

In addition to technology, you need an eye for the little things in nature, patience and always a bit of luck! Knowledge of the behavior of certain groups of insects can also come to great advantage.

Ein besonderes Highlight des Buches ist die wunderbare Sammlung von Insektenfotos, die meisten davon von Ihnen aufgenommen. Haben Sie Tipps für Leute, die sich für Insektenfotografie interessieren?

Das Hauptproblem beim Fotografieren von kleinen Objekten ist immer, einen möglichst grossen Teil davon scharf abbilden zu können. Dies erfordert eine kleine Blende und damit auch viel Licht. Ich fotografiere alles “aus der Hand” und deshalb sollte die Verschlusszeit kurz sein. Aus diesen Gründen verwende ich mit meiner Spiegelreflexkamera und dem 100 mm Makroobjektiv fast immer einen Ringblitz mit separat steuerbaren Blitzhälften. Aber auch Kameras mit kleinem Sensor (sogar Handys!) bringen bei grösseren, wenig flüchtigen Insekten heutzutage erstaunlich gute Bilder. Um ein Insekt möglichst scharf abzulichten, sollte man sich so positionieren, dass das Insekt möglichst parallel zur Kamera steht. Mindestens die Augen sollten immer scharf sein. Natürlich kann man die Schärfenebene für spezielle Effekte auch anders wählen.

Zusätzlich zur Technik braucht es aber vor allem das Auge für die kleinen Dinge der Natur, Geduld und immer auch etwas Glück! Auch Kenntnisse des Verhaltens bestimmter Insektengruppen sind von grossem Vorteil.

6) What’s next for you? Do you have any projects that you are currently involved in that you would like to tell us about?

Professionally I am still working for another year, but of course my interest in insects will not vanish when I retire. I would like to use my pictures in other ways and maybe do another book. Above all, not surprisingly I would like to use the time to photograph insects in the great outdoors.

Was kommt als Nächstes für Sie? Haben Sie Projekte, an denen Sie aktuell beteiligt sind und die Sie mit uns teilen können?

Beruflich bin ich noch ein Jahr tätig, aber damit erlischt mein Interesse an Insekten natürlich nicht. Ich würde gerne meine Bilder noch anderweitig in Wert setzen und vielleicht noch ein weiteres Buch in dieser Art machen. Vor allem aber möchte ich die Zeit nutzen, um – wen wundert’s – in der freien Natur Insekten zu fotografieren.

Thermal Imaging For Ecologists

In the new Summer 2021 issue of Conservation Land Management magazine (CLM) Dan Brown, ecologist and founder of Wild Discovery, provides an overview of thermal imaging technology and how it can be applied in wildlife surveys. Here you can read a summary of the article.

Thermal imaging was originally developed for military purposes but has since been deployed in a variety of fields, including increasingly so in conservation and ecology. It works by using medium- and long-wave infrared radiation to create a heat image called a thermogram – the varying temperatures can be displayed either as different colours, shades or as a monochromatic image. In light of its growing popularity in ecology, this article discusses how this technology can be used in wildlife surveys and what needs to be considered when doing so.

Field applications

One important benefit of using thermal imaging is that species that are usually difficult to survey, particularly cryptic or nocturnal species, can be readily detected. Ptarmigan, for example, can be tricky to spot in scree and boulder fields, and so the use of thermal imaging can be an efficient way to monitor an elusive species such as this with greater accuracy. Also, as this is a non-invasive surveying technique, the behaviour of wildlife can be observed with little disturbance.

Thermal-imaging technology has already been trialled in surveys of a number of different species. In the Forest of Dean, for example, the Forestry Commission uses thermal imaging to monitor wild boar, and the Mid Wales Squirrel Partnership uses it to monitor active red squirrel dreys. This technology can also complement acoustic monitoring for bat surveys – the species of bat can be determined using a bat detector, while thermal imaging can help to identify potential roost sites and enables the surveyor to count the number of individuals present.

Another advantage of thermal-imaging technology is that it works both during the day and at night. Studies of woodcock and nightjar have put this to good use – researchers have been able to locate day-roosting birds and also monitor their nocturnal activity, such as foraging behaviours and flight patterns, with minimal disturbance to the birds.

Potential for other uses in the field

But what else can thermal imaging be used for in species monitoring? Elsewhere in the world, thermal-imaging systems have been fitted to farm machinery to help detect ground-nesting bird species, a method that could be applied in the UK to monitor curlew, lapwing and stone-curlew. Similarly, attaching thermal-imaging equipment to drones could provide an opportunity to survey inaccessible species and areas.

And it doesn’t have to be just warm-blooded animals either. There is huge variation in heat signatures across the landscape, even between different tree species, and so using thermal imaging could aid searches for potential locations for roosting owls, for example, or help to identify possible basking spots for invertebrates and reptiles. There is also potential for this technology to be used to search for insects that display a distinct heat signature in low ambient temperatures, such as queen wasps and bumblebees or larger moths.

Considerations and limitations

When planning and designing surveys and fieldwork, there are a number of factors that need to be considered when using thermal imaging. For instance, its effectiveness can differ depending on the season or weather – the heat signatures of birds and mammals can be masked on sunny days, whereas these signatures are more detectable during overcast days when the ambient temperature is lower. In order to use this equipment effectively, adequate practice and training is required and although there are some training courses available, there is not a huge amount of published guidance on using thermal imaging for wildlife surveys. And even before choosing a thermal imaging scope, it is important to consider its intended use, its detection distance (as this varies between different models), and cost.

In the full article Dan Brown describes how thermal technology works, provides more detail on how thermal imaging can be applied to wildlife surveys and the benefits of doing so, and describes the resources and training that are currently available for ecologists using thermal imaging. Other articles that featured in the Summer 2021 issue include:

River restoration in the Avon catchment of the Cairngorms National Park
The Pirbright Red Deer Project – Surrey’s last ‘wilderness’?

Author Interview with Jo Brown: Secrets of a Devon Wood

One of NHBS’s bestselling books to date, Secrets of a Devon Wood has captivated people across the globe. An exact replica of Jo Brown’s original Moleskine journal, each page features extraordinary illustrations of species such as the buff-tailed bumblebee, blue tit, red campion and oyster mushroom, and are accompanied by detailed observations and notes regarding physiology and life history. Inspiring for naturalists and budding artists alike, this book will be one to treasure.

Jo Brown is a professional illustrator and a blogging sensation. She graduated from Falmouth College of Arts in 2000 with a BA Honours in Illustration and works from her home studio in Teignmouth. She has very kindly answered some of our questions below.

Firstly, could you tell us about your background and how your interest in the natural world began?

I’ve been interested in nature from a very young age and have many early memories of my mum taking me into the garden to show me woodlice, spiders and butterflies. I always knew I was going to be an artist, because it was the only thing I ever really wanted to do. I first explored art at school and had a great relationship with my art teacher. Later, when I left university in Falmouth, I freelanced and took on design jobs and commissions, though often creating content that didn’t speak to me. Nature and art together came much later when I felt able to produce artwork for myself.

We all absolutely love your book and the original way it’s been produced. When you first started your sketchbook, did you anticipate having it published at the end?

No! I wasn’t even thinking about publishing – the journal was a personal project. I realised very early on that when I draw and document things, I remember them. I remember things like Rumex Obtusifolius (the Latin name for Doc Leaf) – it’s been a wonderful learning tool and almost everything I’ve learned about nature, I’ve learned entirely on my own through observation, supported by research.

After putting up a flick-through video of the journal on YouTube in 2019, my followers jumped from 9 thousand, to 20 thousand overnight. This was incredibly overwhelming for someone who is a bit of a recluse and spends a lot of time on their own. I was approached by several publishers and agents from the UK and US, and came out of the other side with an agent, Clare Wallace, and a publishing deal with Short Books. It was genuine recognition of my work and a wonderful moment. Short books allowed me complete creative control and wanted to publish my journal as it was without any changes.

The response to your book has been phenomenal and people all over the world have been inspired by your artwork. What advice would you give to any new, budding artists?

I would say to begin with, if you find or see something that inspires you, whatever it may be – satisfy yourself first. Don’t draw for anyone else – as long as you’re happy with the work that you’re doing and you’re improving your own skillset and artistic evolution; it doesn’t matter what anybody else thinks. It’s not about what’s popular, or to gain recognition or approval – the only approval you need is your own. As long as you put your passion into whatever you’re interested in, nothing else really matters. It’s an absolutely flooded market, but try to find your own way in and fulfil your own needs. Building your own style takes years.

It’s always wonderful to see a combined passion and talent for both art and science, as they are often seen as very separate entities. How do you think art can be better used to encourage environmental awareness?

As people’s attention span seems to have naturally decreased in the age of social media, I try to use my art to stop people scrolling for a minute. If you can hold someone’s attention with an image, you then have a chance to offer up some relevant information in the words beneath – a chance to promote conservation and environmental awareness.

Did you face any challenges while putting together Secrets of a Devon Wood?

Finishing the book under a national lockdown was incredibly pressured. It was very difficult to feel inspired during such a tremendously hard time. In the middle of the first lockdown, I was coming up to the end of the book and the deadline was looming. If it was up to me, I’d have produced 200-300 more pages, but I had to be realistic. After a month extension, and after weeks of sweat and worry, I completed the last 9-10 pages – half of the book was completed in my own garden because of being in lockdown. The most challenging part of producing the book was getting the work on pages.

We’ve heard exciting rumours of a second nature journal – is this something you’re currently working on? What is your focus this time and when might we expect this to be published?

Yes, though the first book took 2 years to create. I have no deadline for the 2^nd Nature Journal, and I have experienced terrible creative block in the third lockdown. When you’re an artist, you need peace and little stress to be in the zone. The 2^nd Nature Journal will be water-based, focusing on species within 3 miles of the coast. Journalling will be an ongoing project for me, even if it isn’t published; I’ll never run out of subject matter! I will also be involved in other books and be selling my artwork online.

British Wildlife book reviews

British Wildlife has featured book reviews since the very first magazine back in 1989. These reviews provide in-depth critiques of the most important new titles in natural history publishing, from nature-writing bestsellers to technical identification handbooks. They are all authored by experts in relevant subjects, which ensures an honest and insightful appraisal of each book featured.

It can be helpful to read a review before deciding to buy a new book, and so since 2018 every review included in the magazine is available to read on the British Wildlife website. Here is a selection of books that have featured so far in the current volume of British Wildlife, all with links to take you directly to the full review.

1. Woodland Flowers by Keith Kirby

“In Woodland Flowers Keith Kirby invites us to look at the ‘wood beneath the trees’ and to consider what its flora can tell us. The focus of this, the eighth volume of Bloomsbury’s British Wildlife Collection (which I have contributed to myself), is on the vascular plants of the woodland floor; to this end Kirby embraces ferns as honorary flowers, but for the most part he steps aside from considering other elements of woodland ecosystems (including the ‘lower’ plants, fungi and fauna).”

2. Entangled Life by Merlin Sheldrake

“This is Sheldrake’s first book, and, while his expertise means that the readers should feel that they are in safe hands from the off, in truth the experience is more like being whisked down a burrow by a white rabbit, or on a tour of Willy Wonka’s research facility: a trippy, astonishing, and completely exhilarating ride.”

3. His Imperial Majesty: A Natural History of the Purple Emperor by Matthew Oates

“Part autecology, part monograph and part impassioned love poem to a species that has captured the author’s heart, the pages offer an enjoyable blend of the Purple Emperor’s recorded history, biology, ecology and conservation.”

4. Britain’s Habitats: A Field Guide to the Wildlife Habitats of Great Britain and Ireland (second edition) by Sophie Lake, Durwyn Liley, Robert Still and Andy Swash

“But do we really need a field guide to habitats? Possibly not. I certainly will not be taking my copy into the field. Yet this perhaps misses the point. What this book does is remind the users of other field guides that their organisms of interest do not live in isolation – they are nothing without their habitats. So, make this book an essential companion to your species guides.”

5. Beetles of Britain and Ireland. Volume 3: Geotrupidae to Scraptiidae by Andrew G. Duff

“Anyone interested in identifying and studying beetles simply cannot afford to be without [these books] and any quibbles can only be minor. Andrew cannot be too highly commended for his diligence and hard work to make so much information available to all.”

Reviewed by Richard Wright in the April 2021 issue (BW 32.5) – read the review here

6. The Bumblebee Book: A Guide to Britain & Ireland’s Bumblebees by Nick Owen

“This is the latest book to enter the now relatively crowded marketplace of bumblebee guides, which may leave one wondering what it can offer to the more seasoned hymenopterist – read on! The author’s intention is to provide a book at the ‘entry level’ of bee study, Owens stating from the outset that he ‘aims to provide an easily accessible introduction for those with little or no previous knowledge of bumblebees’.”

7. Bringing Back the Beaver: The Story of One Man’s Quest to Rewild Britain’s Waterways by Derek Gow

“There is no better place from which to view the tragi-comic events which unfold, and no better person to describe it than Derek Gow, a man of action as well as a powerful Beaver advocate. This account is unexpected, oddball, and, despite its serious side, enormously entertaining.”

FSC: Publisher of the Month for July

Since first featuring as NHBS’ Publisher of the Month over three years ago, the Field Studies Council have added even more excellent titles to their catalogue of publications.

We asked Head of Publications, Dr Rebecca Farley-Brown what hopes and plans the FSC has for the next five years?

‘Plans for next 5 years – more guides in more places. We want to expand the range to help more people get engaged with nature – from simple family guides through to specialist books’.

The Field Studies Council (FSC) is the NHBS Publisher of the Month for July.

The FSC publish six diverse, thoroughly researched and constantly expanding series’, these include: Royal Entomological Society Handbooks, AIDGAP Guides, Fold-out Identification Charts and Chart Packs, Synopses of the British Fauna and Biological Records Centre Atlases.

Fold-Out Identification Charts

The FSC’s range of identification charts are designed to assist nature enthusiasts with identifying and naming the fauna and flora they find. The first fold-out identification chart, The Woodland Name Trail was produced in 1994 and, since then, these guides have become the FSC’s best-selling publications.

AIDGAP guides

In 1976 The ‘AIDGAP’ (Aids to Identification in Difficult Groups of Animals and Plants) project was started, with the aim of producing user-friendly and reliable field guides which would make identification achievable for those with little taxonomic training.

2020/2021 has been busy for AIDGAP, with new guides to Vegetative grasses, Sphagnum mosses and Freshwater Snails all being published.

RES Handbooks for the Identification of British Insects

In 2004 the FSC started working with the Royal Entomological Society to publish their Handbook series. The aim of these handbooks is to provide illustrated identification keys to the insects of Britain, together with concise morphological, biological and distributional information. These comprehensive books are primarily aimed at experienced users.

BRC Atlases

The FSC also publishes Atlases on behalf of the Biological Records Centre (part of the Centre for Ecology and Hydrology). Suitable for more experienced users, these atlases map the distribution of records within Great Britain and Ireland for named groups of animals.

Synopses of the British Fauna

In 1991 the FSC formed a partnership with the Linnean Society of London to publish their Synopses of the British Fauna series. The first Synopses FSC published was Woodlice (now out of print) and since then, over 60 additional volumes have been published.

A busy publishing year for the Field Studies Council

The FSC has been publishing environmental titles for over 40 years and 2020/2021 have been busy publishing years, especially for AIDGAP, with new guides: Grasses, Freshwater Snails of Britain and Ireland and Sphagnum Mosses.

A Blowflies Handbook has also been published for the Royal Entomological Society and an atlas with identification keys for the Histeridae, Sphaeritidae and Silphidae beetles for the Biological Records Centre.

New foldout guides for Moorland Wildlife of the North York Moors and Features of the Gwent Levels were published early in 2021, with guides to seaside plants and woodlands planned for later this summer.
