The NHBS Guide to UK Spider Identification

There are over 650 species of spider within the UK, and although many may find spiders unappealing or even frightening, they are fascinating in their own right. While many spiders are present throughout the year, autumn is the best time to see them outdoors.

Identifying spiders can often be difficult, as they are very small, elusive, and many species resemble one another. The colouration and pattern of a spider can be a useful way to identify them, as well as other key features such as the structure of their webs. In some cases, it is necessary to take a closer look at the genitalia under a microscope, as this can be the only way to confidently identify certain species. You can also use your location as a clue, as some species are more likely to be found in certain parts of the UK.

To survey for spiders, you can search by eye or you can use equipment such as a sweep net or a sampling tray, and a hand lens can help you pick out features on smaller species. There are also lots of field guides and books available for more information on different types of spiders.

In this article, we’ll show you several fairly common species that you may find in your garden or local green space.

**Garden Spider or Cross Orbweaver (Araneus diadematus)**

Distribution: Common and widespread

What to look for: These spiders are greyish-brown or reddish-brown with a white pattern across their back that resembles a cross. They can also sometimes be bright orange. They have striped legs, and females are twice the size of males.

**Noble False Widow (Steatoda nobilis)**

Distribution: Widespread across southern England, with their range increasing northwards

What to look for: This species can be confused with many other UK species. Their body is dark brown, with variable patterns on their abdomen. Usually cream and dark brown marks that can sometimes resemble a skull.

Did you know? This is a non-native species in the UK and was thought to be introduced in the late 1800s. Despite many rumours, bites from this species are rare, usually occurring when the spider is disturbed. The bites have been compared to a wasp sting, however guidance should be sort if you are concerned about a bite.

**Common Candy-Striped Spider (Enoplognatha ovata)**

Distribution: Occurs throughout the UK

What to look for: The common candy-striped spider has several colour variations. Their abdomen usually has a pale creamish-white background. The pattern on it can be bright pinkish-purple in a V shape pointing towards the head, a solid pinkish-purple triangle, black lines that can be either thick or thin, or a variation of black marks and spots. Their cephalothorax (fused head and thorax) is a pale yellow colour, with a dark line down the middle, and their legs are also a similar pale yellow. In the field, it is incredibly difficult to distinguish this species from a similar species, the scarce candy-striped spider (Enoplognatha latimana). Confirmation of the species usually requires examination under a microscope.

**Goldenrod (Flower) Crab Spider (Misumena vatia)**

Distribution: Common in southern UK

What to look for: The goldenrod crab spider has some colour variation, appearing white, yellow or green, They often have red lines on either side of their abdomen. Their abdomen is bulbous and their front legs have a crab-like appearance, hence their name. The female is much larger than the male.

Did you know? This species can change its body colour to match its background! It takes a few days to occur, but it helps to disguise the spider as they sit and wait for their prey to land near them.

**Zebra Jumping Spider (Salticus scenicus)**

Distribution: Widespread

What to look for: The zebra jumping spider can grow up to 8mm, which is surprisingly large for a jumping spider, and they can jump an impressive 10cm. As their name suggests, they have a black and white striped pattern, but it can be hard to tell them apart from similar species of jumping spider. They are usually found on walls, rocks, or tree trunks.

**Cucumber Green Spider (Araniella cucurbitina)**

Distribution: Occur throughout the UK

What to look for: Around 4-6mm long, this small spider has a bright yellowish-green abdomen and a pinkish cephalothorax. They also have small black spots along their abdomen. They are very similar to another cucumber spider A. opisthographa, but it can be difficult to tell them apart in the field.

**Labyrinth Spider (Agelena labyrinthica)**

Distribution: Widespread in southern England, as well as in Wales

What to look for: The labyrinth spider can grow quite large, up to 18mm long. They create long, funnel-shaped webs in long grass and hedgerows. Their abdomen has a pale brown stripe with darker bands on either side, and these bands have several paler chevron markings through them. Their cephalothorax also has a pale brown stripe, with an orange-brown band on either side, and their legs are orange-brown with paler hairs.

**Nursery Web Spider (Pisaura mirabilis)**

Distribution: Widespread across most of the UK, although less frequent in the north

What to look for: The nursery web spider is quite variable in colour, and can have a grey, dark brown, or yellow-orange body. They have a slender, pointed abdomen, with two dark brown lines running from the spinnerets (silk-spinning organs) all the way to the front of the cephalothorax. They also have pale tear-shaped marks next to their eyes.

Author Interview: The Handbook of Acoustic Bat Detection

Acoustic detection is a popular and widespread method of environmental assessment, and its use is increasing, driven by the development of increasingly accessible and sophisticated detection devices. The Handbook of Acoustic Bat Detection provides an in-depth understanding of the principles of acoustic detection, study planning, data handling, properties of bat calls, analysis of results, and the manual identification of species. It also includes information on quality assurance, the benefits and drawbacks of automatic species recognition, and the background physics of sound.

We are fortunate to have had the opportunity to ask the authors some questions.

The applications of data derived from acoustic bat detection are diverse and wide-ranging. What motivated you to write The Handbook of Acoustic Bat Detection and what impact do you hope the book has in this field?

In our daily work, we have seen a lot of improper use of acoustic data. Mainly driven by misconceptions regarding the interpretation of acoustic data and quite often due to missing basic knowledge on bioacoustics and signal analysis. With the easy availability of acoustic detectors and the relative simple usage, these problems became more common, especially in consulting activities. Many new “bat experts” appeared in the field basing their work on automatic detection and identification systems. We hope to help such users to gain a basic understanding of bioacoustics and give more experienced users new information to further improve their work. Thus overall we hope to improve the quality of projects based on acoustic data and increase the evidence level.

This book discusses some of the different methods for processing acoustic data, such as zero-crossing. What are the benefits of this method versus full-spectrum analysis?

The main benefit of zero-crossing is the much smaller amount of data produced and the possibility of listening to the recorded sounds directly. Full-spectrum detectors produce much larger amounts of data and do not allow direct listening to the bat calls. Yet, the benefits of zero-crossing are decreasing with cheaper data storage and higher processing power. Thus today one can nearly instantaneously listen to full-spectrum sound resampled to zero-crossing or heterodyne representation in real-time. In our opinion, the real-time data gives more insights into the calls on a much easier-to-understand level, yet we accept that experts can do powerful analysis with zero-crossing data as well.

You have all had many years of experience in this field; how has bat detection and acoustic analysis developed and changed since you first started?

We started working on bat acoustics in the field when only heterodyne or zero-crossing detectors were available. So in our early days, we walked through the field listening for bats. We were already interested in better and more reliable species ID back then. Then the time-expansion system was available as well as the Anabat system. We used time-expansion a lot, but both didn’t work well for our scientific research interests. So we developed with the batcorder a real-time detector that completely changed bat work in Germany within a few years. Back in the beginning, sound analysis of bat calls was something only a few were able to do. Now with fully automated systems, the whole process changed. Surveys can run for multiple months nearly everywhere – not only ground-based but also on wind turbines or off-shore. We collect billions of bat calls a year with these systems and thus are able to learn more about their calls and ecology. Yet this is not always the best, since a lack of bat knowledge often prevents optimal solutions for bat-related landscape changes.

Bat acoustic recording visualised through the Anabat Insight Software

In chapter 11, ‘Quality assurance of reports’, you provide criteria to improve the quality of specialist reports used in impact assessments, such as which information should be included and the procedures that should be followed. How do you think the previous lack of clear guidelines has impacted bat surveying and, consequently, conservation?

In Germany, quite often surveys were conducted and it was later not possible to understand the low or high results since important information was missing. Also for legal complaints in planning processes, it was quite often impossible to understand how the data was actually sampled. If surveys and methods are well documented, it is much easier to evaluate the planning process and even more to work out optimal sampling schemes for following surveys in the new planning processes.

Now that this book is complete, do you have any future projects you would like to tell us about?

There are many projects – especially since we now face a major green-green dilemma with climate conservation often acting against biodiversity conservation. This especially is visible in the renewable energy sector. So currently some of us are investigating chances to further identify the possibilities of improving bat conservation for planning wind parks and other sources of renewables.

Another project is the ongoing improvement of species identification based on bat calls. We are working on new solutions to give better results.

Book Review: Silent Earth by Dave Goulson

On the 27th of September, 1962, marine biologist and conservationist Rachel Carson saw her book, Silent Spring, published. A powerful examination of the effect that humans have on the natural world, with a particular emphasis on the use of pesticides, Silent Spring met with rapid success and soon became a landmark text on the subject. Despite fearsome opposition it became a rallying point for the environmental movement, fuelling discussions that would result in the widespread re-evaluation of the damage that pesticides can cause and the banning of some of the most damaging chemicals, such as DDT.

Dave Goulson’s new book, Silent Earth: Averting the Insect Apocalypse, is at once a tribute to Carson’s masterpiece and an innovative new work in its own right. Building upon Carson’s inspirational text, Silent Earth provides an up-to-date analysis of our impact upon the natural world over the last sixty years and beyond. The message is simple: despite the advances we’ve made, the warnings of Silent Spring have gone terrifyingly unheeded and without action we might soon find ourselves in a situation that we cannot reverse.

Goulson is a biology lecturer and leading expert in insect ecology, particularly bumblebees, as well as a highly respected scientific writer with several books and hundreds of published papers in his portfolio – it comes as no surprise that Silent Earth is both supremely well researched and beautifully written. It is written in five parts. The first, “Why Insects Matter”, is a fascinating delve into the significance of insects both to the natural world and to human society. With an expert eye, Goulson skillfully guides the reader through different aspects of their importance, from the multi-million pound service that dung beetles provide the farming industry each year in the UK alone to the vital role that pollinators play in underpinning ecosystems across the planet, and the value that insects have in their own right as beautiful, vibrant denizens of our planet. The author’s passion is infectious; it is difficult to read this section without becoming invested in the wondrous ranks of the planet’s invertebrates, making the threat of their decline feel all the more personal.

In the next two parts, “Insect Declines” and “Causes of Insect Declines”, Goulson introduces the sources of evidence that can be drawn on to track insect declines and explores some of the reasons why society seems oblivious to our dwindling invertebrate fauna. He then moves on to explore in detail the various pressures upon their populations, examining and evidencing each before moving on to the next. Goulson writes with respect for the reader, never over-simplifying his prose while providing ample detail to engage any reader, be they a newcomer to the field, amateur enthusiast, ecology professional or academic. Particularly notable is the way in which Goulson details his own work, which has at times proved controversial among some parties. He consistently highlights the arguments of his critics, treating them with respect and validation. At some points he provides his rebuttal while at others he admits to the shortcomings of the relevant research, explaining why a different approach was impossible at the time. This is indicative of an attitude that permeates the book – the issues that he writes about are bigger than minor gripes with experimental methodologies, bigger than business margins or political leanings. He presents with a neutral eye the irrefutable reality that insects are vanishing at a terrifying rate, and unless action is taken the world is heading towards a very real disaster within generations. Though frequently distressing and at times heartbreaking, Goulson writes with a voice compelling and just witty enough to prevent the reader from becoming despondent. This book is not intended to drive us to despair, but to action.

Part Four – “Where Are We Headed?” – is a brief but poignant exploration of the author’s vision of the future. From another writer, this might seem like a flight of fancy, but from Goulson it comes across as a warning every bit as earnest and necessary as the hard science of the preceding chapters. It acts as a kind of crescendo, a snapshot of the future that the author is trying to warn us about, as well as a perfect segway into the final part. Perhaps most importantly after the relentlessly grim picture painted in “Causes of Insect Declines”, it ends with a ray of hope.

The fifth and final part of the book is simply titled “What Can We Do?”. It lists from the point of view of the author – a researcher, educator, and father – the actions that should be undertaken by everyone in society, from members of the public to researchers, farmers and politicians, among others, to begin to turn the tide. Various key actions are explored in detail – the importance of instilling an environmental ethos in young people, of encouraging native plants in our towns and cities and overhauling the way in which we view farming. Finally, there is an extensive list of actions, large and small, that people can take, listed by occupation. This section is what the book has been building to, and it is worth reading for this alone. As usual, respect is paid to all viewpoints and all members of society. It doesn’t matter whether the reader is in a position where a free-range organic, locally sourced diet is financially viable or not – there will be other actions that they can take regardless of financial matters. Nor does it matter if they have beliefs, political or economic, that might conflict with the author’s. It is a call for society to overlook such matters which are, in the face of such a crisis, trivial.

Silent Earth: Averting the Insect Apocalypse is, in my opinion, a masterpiece of popular science writing. It is a feat to present such dire information in a way that is not only readable, but also engaging and compelling – Goulson’s prose manages never to lose the reader for a moment. It is a stark, hard-hitting warning, but one that must be heard by as many people as will listen. Moreover, it goes far beyond the reactionary doomsayings sometimes written on the subject to provide an inspiring manifesto for change. It equips the reader with the knowledge that they need to understand the problem, and the actions they can take to enact this change. It leaves you with the impression that, if the message can get through to enough readers across the world, we might just be able to turn the tide and preserve the buzzing of bees, the chirping of crickets and the droning of cicadas to prevent the silence falling for good.

Climate Challenges: 2. Forest Fires

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 increase in the prevalence and intensity of forest fires, and how they can be both exacerbated by and contribute to climate change.

How and why do forest fires occur?

In many ecosystems forest fires are a natural event and, particularly in high-latitude forests, can help to maintain a healthy ecosystem, release nutrients into the soil and help with seed dispersal. Fossil charcoal remains suggest that natural fires have occurred since the appearance of terrestrial plants 420 million years ago and were caused by lightning or volcanic eruptions. While these factors are still responsible for a number of forest fires, human-ignited fires, such as those caused by discarded cigarettes, poorly controlled bonfires or cooking fires, sparks from electrical equipment and intentional arson, are now increasingly prevalent. Controlled fires are also used to manage farmland and pasture, and to clear natural vegetation. How quickly and efficiently a fire will spread depends largely on the amount and type of flammable material present, along with the local topography, moisture levels and weather conditions.

When and why are forest fires a problem?

A combination of climate change and poor land management mean that many areas are now much more prone to forest fires than they have been historically. In particular, hotter and dryer conditions, combined with ecosystems that are degraded by logging and disease means that fire seasons are becoming much more extreme and widespread. This is especially worrying in tropical rainforests, where forest fires would previously have been rare.

Increased occurrences of forest fires pose a number of environmental, social and economic problems. As well as damaging forest ecosystems, large-scale fires release copious amounts of CO₂ and pollutants into the atmosphere, which are problematic both from an environmental standpoint and as a significant human health concern. Over the past century, wildfires have accounted for 20-25% of global carbon emissions – a worrying statistic that illustrates the environmental significance of the problem. In addition to this, the economic impact of fires can be considerable, with damage to property and tourist attractions, pollution of water supplies and the cost of evacuating local residents being some of the main problems.

Are forest fires ever a good thing?

As mentioned previously, wildfires have occurred throughout the history of terrestrial life, and many species have evolved to cope with or thrive under the conditions that they produce. Particularly in areas such as the vegetated regions of Australia, the celd in southern Africa, the fynbos in South Africa and the forested areas of the US and Canada, forest fires are common and help to create what is known as ‘snag forest habitat’. These areas feature higher species richness and diversity when compared to unburned forest, and their soils are rich from the plant nutrients that the fires help to return. Furthermore, many of the native plants that thrive in these areas rely on fire for successful germination of their seeds. Some of these ecosystems, however, are now suffering from too much fire, which has upset natural cycles and altered the previously well-balanced plant communities.

What can be done to prevent and control forest fires?

1996 poster from Rotorua Forest Service. Image by Archives NZ via Flickr.

Forest fire prevention attempts to reduce the risk of fires, as well as minimising their intensity and spread. One of the key methods is to educate and raise public awareness of the human-involvement in forest fires. In Europe, more than 95% of fires are caused by humans, and so addressing this is considered to be the most effective means of reducing unplanned forest fires. Closely controlling the use of planned burning is also important, as fires that are conducted under less dangerous weather conditions are much more likely to be successfully contained. The intentional igniting of small areas of vegetation is also used to minimise the amount of flammable material available for future forest fires and, when conducted carefully, can also help to maintain high local species diversity. However, this method is often unpopular due to the economic losses associated with burning potentially usable timber. Another method, particularly popular in the US, involves a fuel reduction strategy that involves logging and thinning overstocked trees.

Summary

• Although forest fires have occurred naturally since the evolution of terrestrial vegetation, climate change and changes in land management have produced conditions that are much more favourable for long, intense fire seasons.
• Forest fires make a significant contribution to global carbon emissions, destroy important habitat and can cause local widespread desertification.
• Current methods of controlling and preventing forest fires include widespread education to minimise the unintentional starting of fires by the public, as well as controlled small-scale burning of vegetation and clearing overstocked trees.
• Despite this, forest fires continue to be a significant challenge. They contribute to the climate crisis and pose a significant risk to wildlife and human life and health.

Author Interview with James Aldred: Goshawk Summer

James Aldred is an award-winning documentary wildlife cameraman and filmmaker. James has collaborated on numerous high-profile projects with Sir David Attenborough, including Life of Mammals, Planet Earth and Our Planet, resulting in several BAFTA/RTS nominations. He is also the author of The Man Who Climbs Trees.

In his latest book, Goshawk Summer, James details his extraordinary and unique experience documenting a family of goshawks in the New Forest during the national lockdown of 2020. We have had the very fortunate opportunity to ask James some questions

Could you tell us about how you first came to be interested in the natural world?

Through time spent outdoors in the New Forest, where I spent much of my childhood. My teenage obsession was tracking deer, particularly Red, which were quite scarce in the Forest during the 1980s. I also got into tree climbing at an early age. Many of my friends were training to be foresters and tree surgeons and they showed me how to use ropes to access the forest canopy. I immediately fell in love with this hard-to-reach, but wildlife-rich environment and regularly took my stills camera up with me to try and capture images of the New Forest from this unique perspective.

Travel restrictions due to the Covid-19 pandemic presented a unique opportunity to document nature with very little human interference. Do you think this period of time will have had any lasting impacts on the country’s wildlife?

Yes, but in a rather unforeseen way. The space provided by the initial lockdown period definitely helped those birds and animals with a shorter breeding cycle, but ultimately the lockdown period was too short to be of much lasting benefit to a lot of the larger wildlife, including large ground-nesting birds such as curlew. The levels of disturbance in the post-lockdown period were very high in some places and this had the unfortunate effect of causing problems for those species that had not yet completed their breeding season. Ironically though, these high levels of disturbance in the countryside in the immediate aftermath of lockdown may yet provide useful data in terms of how best to manage large visitor numbers in the future as our population increases to grow and national parks are placed under increased pressure.

To capture footage of the goshawks required time, patience and understanding, but your efforts were clearly rewarded. Do you have any particular highlights from your goshawk summer?

There were so many, but I think the nesting dynamics between an adult male and female were particularly fascinating. Their relationship was surprisingly complex, subtle and even-keeled for such a fiery bird. The male often covered the clutch to keep the eggs warm whilst the female fed off site, and was even allowed to feed the chicks himself on several occasions whilst the female stood by and looked on. Very unusual for Goshawk females to tolerate their mate being so close to the chicks like this.

For a young aspiring naturalist, a career as a wildlife photographer would seem to be an ideal choice, especially since our collective experience and knowledge is usually limited to what we see on film/television or on paper. Could you tell us a bit about the reality of what it’s like to be a wildlife cameraman?

The reality is very anti-social working hours, high levels of frustration and a huge impact on home life! But I wouldn’t change it for the world as it is undoubtedly one of the most soul-nourishing jobs you could ever hope to do, in my opinion. It’s a tough, highly competitive industry, but this doesn’t mean you can’t get in through gentle persistence and dedication. Knowledge is everything: read, watch and learn everything you possibly can about your chosen wildlife subject before even attempting to film it.

What’s next for you? Do you have any current or future projects planned?

I’m currently working on a large project commissioned by a popular US-based video-on-demand provider. I’ve just been filming in the Congo for them and due to head out to Borneo soon. I’m also working on an exciting UK-based project about rewilding, which is a subject I find particularly compelling and relevant. All the more so since it is UK based and has the potential to inspire the next generation of naturalists.

Book Review: A Trillion Trees by Fred Pearce

A Trillion Trees is an optimistic take on the future of the world’s forests, with Fred Pearce believing that the damage humanity has inflicted can be undone, so long as nature is allowed space to recover. The book opens with an introduction to the myth and magic of forests. Through describing a botanical explorer’s conservation of orchids in the rainforests of Ecuador, recounting one of the author’s most memorable forest experiences (getting lost in a wood on the North Downs as a child), and presenting the varied reactions of early European explorers to the rainforests of the tropics, Pearce laments the loss of ‘primaeval wildness’ and the untouched forests of those times.

Since 1992, Pearce has been writing for New Scientist magazine on the importance of trees, as well as their ownership, uses, protection, and destruction. He has spent his career contributing to multiple well-known publications, writing a range of books, and speaking on environmental issues such as carbon emissions, invasive species, and climate change. Despite forty years of continued reporting on global environmental issues, he maintains optimism for the future and for forest regrowth.

Pearce’s enthusiasm and respect for trees is clear throughout. This book celebrates trees, exploring their importance and the impact they have on the climate, the history of how our relationship with forests has changed, the recovery that is already taking place, and the future role of trees in an emerging community-centred approach to the land. Pearce intersperses topics on the politicisation of forest and climate research, the impacts of deforestation, and the damage of acid rain. He also includes some of his personal adventures, such as his visit to the ATTO, a 325m tall tower in the middle of the Amazon Rainforest, and the exploits of others, such as a bush pilot’s flight along the ‘flying river’ above the Amazon.

A Trillion Trees champions the role of trees in more than just the fight against climate change, but also in the daily lives of everyday people. The tales of forest regeneration tell of the economic value of trees, through tourism, increased resources, and even ‘inspiration for artists’. Pearce presents the debate of rewilding versus replanting forests, asking who should be responsible for the regeneration of our forests and whether we should be taking an active role at all. The ‘great forest restoration’, as Pearce puts it, is occurring less due to the many government plans and promises of replanting, and more through the process of rewilding. Where farmers and landowners have stepped back, Pearce notes that nature seems to move in, allowing much of the fields and pastures to revert to shrubland and then to woodland. The return of wildlife soon follows.

In a world scrambling for solutions to combat climate change, the notion of stepping back and taking a passive role in regeneration may be a daunting one. However, it is not the only solution Pearce suggests. In the final section, Forest Commons, the author advocates for the rights of indigenous people to own and manage the land and forests within their traditional/ancestral territories. The rate of deforestation is far less in areas owned and managed by indigenous people than in other areas, even nature reserves, with communities seeming more resilient against threats such as illegal logging than government-owned parks.

This book closes by paying homage to the wild spaces near the author’s home in London, their ability to filter out noise and pollution, and the calming, cooling effects trees can have in otherwise overheated cities. After a book full of adventure and debate, the postscript acts almost like the ‘forest bathing’ it discusses, ending the book in a calmer tone that calls for more woods full of darkness and gnarled, twisted yew trees and forests that harken back to the lost primaeval wilderness.

The NHBS Guide to UK Coastal Bird Identification

The UK coast is home to many different bird species, which play a key role in the coastal ecosystems. They depend, directly and indirectly, on the marine and coastal environment. Seabirds are often used as bioindicators of marine ecosystems as they are easy to detect and survey, and are top predators; their presence and abundance can indicate the health and status of the habitat and food chain.

This guide contains some key identification features to look out for while out birdwatching by the coast. It is possible to see birds along our coastline throughout the year, but in late spring and early summer, particularly around June, many seabird species are feeding chicks. This is, therefore, the best time of year to spot some of our iconic coastal birds.

Very little equipment is needed for birdwatching, but it is generally recommended to bring a pair of binoculars or a scope, as this helps to see the less obvious features that aid in identifying species. These also allow you to observe without getting too close and disturbing the wildlife. A pen and notebook to keep a record of the species you spot is also a good idea, along with a field guide for the species not mentioned on this list.

Herring gull (Larus argentatus)

Size: length (L): 54-60 cm, wingspan (WS): 123-148cm

A widespread and common (though declining) gull species across the UK. They are large white birds with grey back and wings (tipped with black), a yellow bill and pink legs, and can be seen far inland in almost any habitat from the coast to farmland, moorland, town and city. This highly versatile species is our archetypal ‘seagull’.

Lesser black-backed gull (Larus fuscus)

Size: L: 48-56cm, WS: 117-134cm

Slightly smaller than the herring gull with darker slate-grey back and wings. Look out for yellow legs which are a key identifier of this species. Favours rocky coasts but is also found inland in mixed flocks with other gulls and around inland lakes.

Lesser Black-backed Gull by Francesco Veronesi via Flickr

Great black-backed gull (Larus Marinus)

Size: L: 61-74cm, WS: 144-166cm

These are very large and stocky gulls with a dark grey back and wings, a thick-set yellow bill and pink legs. This species are far more prominent along coastal areas and nest largely on rocky islands.

Great Black-backed Gull by Tony Hisgett via Flickr

Black-headed gull (Chroicocephalus ridibundus)

Size: L: 35-39cm, WS: 86-99cm

Another widespread and common species often found inland, black-headed gulls have white heads for most of the year, often with a prominent black ear spot. In the summer, adult birds heads turns a dark chocolaty brown. They also have a red bill and red legs.

Black-headed Gull by Ian Preston via Flickr

Kittiwake (Rissa tridactyla)

Size: L: 37-42cm, WS: 93-105 cm

A somewhat slight looking gull, white bodied with pale grey back and wings and black wing tips. They have a small yellow bill, dark eyes and black legs. Predominantly a summer breeding species in the UK and very rarely seen away from the coast, though they are known to form colonies within urban areas near ports.

Common tern (Sterna hirundo)

Size: L: 34-37cm, WS: 70-80 cm

Slight, slender and angular birds, often breeding in colonies around coastal lakes and lagoons, common terns are bright white with a light grey back and wings, a deeply forked tail, black cap and red legs and bill. Their bill has a black tip.

Common Tern by Jevgenijs Slihto via Flickr

Arctic tern (Sterna paradisaea)

Size: L:33-39cm, WS: 66-77 cm

For much of the UK Arctic terns will be spotted on passage during their incredibly long migration. They are superficially similar to common tern though their bill is usually plain red with no black tip.

Arctic Tern by Lindsay Robinson via Flickr

Fulmar (Fulmarus glacialis)

Size: L: 43-52cm, WS: 101-117 cm

Fulmar, though gull like in appearance, are petrels, related to albatrosses and shearwaters. They have a thick-set ‘tube-nose’ bill which they can spit foul-smelling oil from to deter predators from their nesting sites. They nest on sheer cliff faces and fly on stiff and shallow wing beats.

Gannet (Morus bassanus)

Size: L: 85-97cm, WS: 170-192 cm

Gannets are large white seabirds with a distinctive yellow head and long pointed wings with black tips. They also have a long pointed grey bill and white pointed tale. They can be seen flying high over the sea and circling before plunging at great speeds into the water in pursuit of food.

Guillemot (Uria aalge)

Size: L: 38-46cm, WS: 61-73 cm

Guillemots come to land only in the summer to breed and do so in large colonies on sheer cliff faces. Adult birds can often be seen ‘rafting’ at sea below the colony also. They have a brown/black head, back, wings and tail and white underneath. There is also a ‘bridled’ form where the birds have a white ring around their eye with a stripe behind it.

Razorbill (Alca torda)

Size: L: 38-43cm, WS: 60-69 cm

Razorbills are superficially similar to guillemot: black on their wings, back, head and tail and white underneath. An easy distinction between the species can be made however, by the razorbills deep thick-set blunt bill, where the guillemot has a longer slim bill. They are another summer breeder, wintering in the northern Atlantic, and favouring sheer rocky cliffs and islands for nesting.

Puffin (Fratercula arctica)

Size: L: 28-34cm, WS: 50-60 cm

Unmistakeable small seabirds with a black back and white underneath. They have a white face with dark eyes set in dark triangular markings and an iconic vibrantly colourful bill. They are a summer visitor predominantly in large nesting colonies on islands, where they nest in burrows along vast grassy banks.

Cormorant (Phalacrocorax carbo)

Size: L: 77-94cm, WS: 121-149 cm

A large long-necked black bird, with a white face and yellow and grey bill. Cormorants are often seen inland on rivers and lakes, and in harbours where they extensively dive for their food and then stand to dry with their wings characteristically spread wide.

Cormorant by Dirk-Jan van Roest via Flickr

Shag (Phalacrocorax aristotelis)

Size: L: 68-78cm, WS: 95-110 cm

Shags are similar in appearance to cormorants though smaller, with a slimmer bill. Adult birds are entirely black (lacking the white face of cormorants) though still they have a yellow and grey bill. Shags are more strictly coastal and seldom seen inland, they also have a distinctive black crest on the top of their head.

Rock pipit (Anthus petrosus)

Size: L: 15.5-17cm

Synonymous with the coast, these small, streaked brown/grey birds (with pale underside) are commonly seen flitting from rock to rock with a swift undulating flight. They have a light peeping call and can be seen perching around harbour walls -they are often quite plucky and approachable.

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.
