The NHBS Introduction to Habitats: Urban and Suburban

The next habitat we will be exploring in our Introduction to Habitats series is urban and suburban habitats. These are extremely diverse, from parks, gardens, cemeteries and bare ground to highrises, bridges, landfills and houses. Due to this wide diversity, urban habitats are often extremely fragmented, with small, isolated patches surrounded by unsuitable areas. These patches are also often highly disturbed, by light, people, pets, cars and other anthropogenic activities. Some species also have to deal with reduced availability of food, due to the limited plant life, and fewer nesting and breeding spaces. Much of the surfaces in the urban environment have been altered, covered in concrete, roofing tiles, and tarmac. This changes the amount of rainwater that can infiltrate the soils underneath, as well as how much heat from the sun is absorbed. The temperatures can be higher in urban areas, particularly when there is little to no tree coverage to provide shade.

To survive in an urban environment, species must be adaptable. Many studies have found key behavioural and physical differences between urban and rural dwellers of the same species. For example, birds have been found to sing higher, longer and louder in cities than in the countryside. Generalist species are more likely to be able to exploit these habitats as they can occupy wider ecological niches. Specialist species can have more restricted diets or need more specific conditions to develop or reproduce, making them less able to adapt to changing environments. Those able to transition from natural to man-made habitats, however, may actually see large fitness benefits, due to fewer predators and, for some species, abundant food supplies.

Gardens and public green spaces can often be a refuge for many urban species, providing food, shelter and protection from other disturbances. But overly manicured gardens and parks do not provide the resources necessary for many species to survive. Wildflowers, hedges, shrubs, trees and other native vegetation are needed to boost insect numbers, along with limiting the use of harmful herbicides and pesticides. Many other species rely on insects for food, and so increasing insect populations benefits other species throughout the food web.

What species can you find here?

Flora:

Cow Parsley (Anthriscus sylvestris)

This species is a member of the carrot family and is commonly found on verges, hedgerows and less intensively-managed green spaces, with a preference for shaded habitats. It is a fast-growing plant, that appears in the summer before dying back, and its white flowers are clustered together in an umbrella-like shape. They are a great food resource for many invertebrate species, as well as for rabbits. There are several similar-looking plants, including the poisonous hemlock (Conium maculatum), although hemlock has distinctive purple blotches on its stem.

Three-cornered Garlic (Allium triquetrum)

This is an invasive species, often found along verges, roadside banks, hedgerows and on waste ground. It can form dense colonies and are spread naturally by ants. Its white flowers have a green stripe on each petal and a garlic/oniony smell. They are edible, tasting similarly to spring onion or chives.

Common Chickweed (Stellaria media)

This plant has multiple common names, including chickenwort, maruns, craches and winterweed. They form large mats and are found in many gardens and fields. It has one line of fine hairs on its stem, with oval leaves and small white flowers. Chickweed was used in folk medicine as a remedy for pulmonary disease and several itchy skin conditions. It is even prescribed today by modern herbalists for many other conditions, although not all these uses are supported by scientific evidence.

English Ivy (Hedera helix)

This is a climbing plant that can often be found on walls, buildings, trees and other man-made and natural structures. It is an evergreen species that can also grow as groundcover when there are no vertical surfaces. The flowers are a greenish-yellow colour and the fruits, which ripen in late winter, can vary in colour from purple-black to orangy-yellow. They are an important food source for many insects and birds, particularly in autumn and winter, and their foliage is also browsed by deer.

Fauna:

Feral Pigeon (Columba livia domestica)

There are several species of pigeon in our urban areas. Feral pigeons, also known as city or street pigeons, are descended from the domestic pigeon, a subspecies derived from the rock dove (Columba livia). They have substituted their natural habitats of sea cliffs with ledges on buildings and other man-made structures. They have a wide variety of colours and patterns compared to the rock dove, but urban pigeons tend to have a darker plumage compared to individuals in rural areas.

Red Fox (Vulpes vulpes)

An iconic urban species, the red fox is one of our largest land predators. Usually living in groups or pairs, they feed mainly on small mammals and birds, but also amphibians and fruit. In urban areas, they are very successful scavengers, helped occasionally by people who leave food out for them. They are more common in less dense suburban areas but have been found right in city centres. It is thought that the movement between urban and rural fox populations is quite fluid.

European Hedgehog (Erinaceus europaeus)

Another iconic British species, the hedgehog has seen severe population declines, though true population estimates are difficult, due to the lack of data and their elusive nature. In the 1950s, population estimates put the number of hedgehogs in the UK at 36.5 million (although this is not thought to be accurate), which is now thought to have dropped to 1.55 million by 1995. It is believed that populations are still declining, but there are still no reliable methods for estimating the true numbers. They face several threats, including habitat loss, chemical use in gardens, cars and a drop in invertebrate populations.

Peregrine Falcon (Falco peregrinus)

This bird of prey is not only the fastest bird in the world, but also the fastest member of the animal kingdom, clocking up a dive speed of over 320km/h. Their populations suffered after decades of persecution and pesticide use, but their numbers have begun to recover. They nest in tall buildings, bridges and pylons, and prey mainly on pigeons but also collared doves, blackbirds and starlings.

Garden Snail (Cornu aspersum)

A wide variety of invertebrates can be found in urban and suburban habitats, particularly gardens and parks. The garden snail is a common visitor to our lawns, plants and vegetable patches. They’re often considered a pest due to the damage they cause to leaves and fruits but they play a vital role in the health of our soils. They help decompose plant matter, allowing for the cycling of nutrients back into the soil. Snails are also an important food and calcium source for many animals, such as birds.

Urban and suburban environments are also home to many garden bird species, as well as bats, butterflies, moths and spiders. For more information on these, check out some of our guides to UK species identification.

Threats

Urban and suburban areas are becoming more and more densely inhabited as more of the UK’s population moved into towns and cities. This increases the levels of disturbance, from more cars on the road, more noise, light, waste, pets and people. Higher disturbances decrease the ability of species to survive, as they are less likely to feed, develop and reproduce successfully. It can also increase the likelihood of direct mortality.

With a rising human population is an increasing need for more housing and infrastructure. Consequently, this reduces the amount of undeveloped and semi-natural areas; fewer green spaces and the over maintenance of gardens and parks are serious threats to biodiversity in urban habitats.

Public opinion can also threaten urban wildlife. Many species that have managed to colonise the urban environment are considered pests and there are often calls to eradicate them. Fox culls are a controversial suggestion, with many people wanting a way to control the populations and reduce the damage they cause, while others are concerned with animal rights. Additionally, there are suggestions that culls are ineffective, as removed foxes are often replaced by another individual, with no change made to urban population numbers.

What can you do to help?

There are several simple steps you can take to help improve urban biodiversity. You could plant more native plants, reduce the chemicals you use and decrease how often you mow your lawn. Placing bird feeders, nests, and other shelters are also ways that can help wildlife. On a bigger scale, you can urge your local council and government to help too. They could increase the areas of green space and tree cover, and manage roadside verges with nature in mind. Another important step is to decrease light and noise pollution. With some simple steps, we can help to increase the suitability of urban habitats for many wildlife species.

The NHBS Guide to UK Goose Identification

Geese are birds in the family Anatidae, comprising mainly of the genera Anser and Branta. They are a common sight in our estuaries and other wetlands, particularly during autumn and winter. Many species are migratory visitors to the UK, arriving in autumn and leaving again in spring to places such as Greenland and Iceland. There are some resident goose species, however, which are present all year round, such as greylag and Canada geese.

They feed mainly on seeds, grass, other water plants and some small invertebrates. They are primarily grazers and can search for food both on land and underwater. In UK species, males and females rarely differ in colour, though males are usually larger in size. Geese are monogamous and often pair for life, but several studies have noted evidence of extra-pair copulation (mating outside of this pair bond). One study, for example, found evidence of extra-pair copulation in 14% of 42 Canada goose clutches.

Identifying geese can be based on colouration, distribution, calls, time of year and size. Very little equipment is needed for birdwatching, but we recommend a pair of binoculars or a scope, along with a guide to other waterfowl you may see.

Greylag Goose (Anser anser)

Distribution: Resident population is widespread throughout the UK, although less common in Wales and southwest England. Scottish and southwest England populations are boosted by winter migrant numbers.
Birds of Conservation Concern 4 (BoCC4) Status: Amber
Wingspan: 147–180cm
What to look for: The greylag goose has a grey body and a brown back. It has a brown and grey striped neck, an orange to pink bill and pink legs. They have a paler tail and pale secondary feathers that stand out in flight.

Canada Goose (Branta canadensis)

Distribution: Resident population, widespread, although less common in Scotland and Ireland.
BoCC4 Status: Not Assessed
Wingspan: 150–180cm
What to look for: The Canada goose has a black head, neck and bill, with a white patch on its throat. They have a white underside and a brown back, with black tail feathers and black legs.
Did you know? Canada geese are not native to the UK and were introduced from North America in the 17th century.

Egyptian Goose (Alopochen aegyptiaca)

Distribution: Resident population in East Anglia and southern coastal areas, with winter migrants in southeast England. The largest population is along the Norfolk coast.
BoCC4 Status: Not Assessed

The NHBS Guide to UK Duck Identification

Ducks are waterfowl from the family Anatidae, which also contains geese and swans. They are mostly aquatic birds and there are several resident, breeding and migrant species in the UK. Ducks are split into multiple families, or ‘tribes’, such as dabbling ducks (Anatini), diving ducks (Aythyini) and sea ducks (Mergini). All ducks are generally elongated and broad, with long necks. They have bills and strong, well-developed legs for swimming. The males often have more elaborate plumage than the females, and often similar-looking females of different species can be confused.

Ducks eat a wide variety of food, including vegetation, fish, invertebrates and small amphibians. They have multiple predators including foxes and birds of prey, such as hawks or owls. Ducklings are particularly vulnerable and can also be taken by herons, pike, rats, mink and weasels.

Winter is a great time to birdwatch for ducks in the UK: some species occur in much higher numbers compared to the summer months, and 3 of the 22 species that occur in the UK can only be seen in the winter. The best places to see ducks are lakes, marshlands, estuaries, coastal bays and other wetland areas.

The best equipment for birdwatching is a pair of binoculars or a scope, a notebook and pen to record your sightings, and a guide for more information on other species of duck.

Shelduck (Tadorna tadorna)

Distribution: Present in almost all coastal areas in the UK year-round, as well as some inland waters such as reservoirs.
Size: Length (L): 55–65cm, wingspan (WS): 100–120 cm
Birds of Conservation Concern 4 (BoCC4) Status: Amber
What to look for: Shelducks are a large, boldly-patterned and colourful duck with a white body, dark-green head and red bill, a chestnut band around their chest and pink legs. They can be spotted along estuaries and on the coast.

Eider (Somateria mollissima)

Distribution: During the breeding season, they’re most common northwards from the Northumberland coast and off the west coast of Scotland. During the winter, their range expands to include areas along the east and south coasts, parts of the southwest coast and some areas of the Welsh coast.
Size: L: 60–70cm, WS: 95–105 cm
BoCC4 Status: Amber
What to look for: Eiders are large and impressive sea ducks (rarely seen away from the coast) with distinctive wedge-shaped heads. The males are boldly marked in black and white with subtle green and yellow markings on their head and neck. The females are a dark mottled brown colour all over, providing camouflage during nesting.

Goldeneye (Bucephala clangula)

Distribution: Mainly restricted to the highlands of Scotland during the summer, their winter range includes most coastal areas, lakes, large rivers and other inland water bodies. They are particularly best looked for in north and west Britain.

Trees for Life: Q&A with Alan McDonnell

Alan McDonnell, Conservation Manager for Trees for Life, kindly took the time to answer some questions on the important work they do in the Scottish Highlands and their ambitious East West Wild project. The Caledonian Forest has been under threat for thousands of years and, by the 1950s, only 1% of the original forest remained. Since its creation in 1993, Trees for Life has worked tirelessly to restore this forest and its ecosystem.

In this captivating conversation, we discuss the importance of working in collaboration with landowners and local communities, how the Covid pandemic has affected them as a charity, and share different ways to get involved in helping Trees for Life achieve their goals.

Could you begin by introducing us to the goals of Trees for Life and the work that you do?

We are a rewilding charity working in the Scottish Highlands. For us, rewilding is about allowing natural processes to work on a large scale. It’s about creating potential for communities to thrive as a result of the health of the natural environment around them.

Our work has therefore increasingly focused on involving people close to where we operate. Our volunteering programme places an emphasis on nature connection. This includes practical action like planting trees, restoring peatlands, and working in the tree nursery at our Dundreggan conservation estate. In recent years, we’ve been increasing our partnerships with others interested in using nature to benefit people’s mental health. We find this hugely rewarding for everyone involved.

Our practical rewilding work includes restoring red squirrel populations to parts of their original range in north and west Scotland and communities play an important role in supporting that. We’ve also just completed an assessment of the health and resilience of Scotland’s ancient pinewoods, which we hope will be just the start of a journey to secure and expand these iconic woodlands in partnership with land managers. Finally, we continue the work Trees for Life started with, restoring native woodlands to appropriate parts of the landscape.

On your website, you state that you believe you can always achieve more through teamwork. Why do you think it is so important for Trees for Life to collaborate with landowners and local communities?

One way or another, we all have a stake in the land and an influence on its future, but people’s priorities are different. If we focus too much on our own interests in isolation, we end up in conflict. This tendency has dogged the land management debate for decades, to the detriment of everyone. We want to help change the focus to one where landowners, communities, and environmental interests look at what they have in common and what they can achieve together. We’ve already seen how this can create new possibilities for sustainable progress, and at a larger scale, for nature, people’s wellbeing, and the local economies that communities depend on.

You have several major projects in the works, including your very ambitious East West Wild project. This project aims to form a coalition of landowners and communities to create a nature-based economy, could you tell us a bit more about what this entails?

The initiative is founded on the precept that nature, communities, and the economy need each other – if one fails, sooner or later it will take the others with it. East West Wild looks at it the other way round: progress in restoring the health of nature in a large landscape can be a catalyst for both social and economic regeneration. We already know that given time and a little help, nature can surge back, so our focus now is how that could create opportunities for people and local businesses. A scoping study has identified nature-friendly forestry, farming, private investment in ecosystem services and small-scale renewable energy as some of the ways in which we can help nature to recover. Such an approach could also create jobs, and sequester carbon through sustainable land use. We’re under no illusions about the challenges involved in attracting the investment to turn these ideas into reality. But we’re also really excited about having the chance to go for such big gains as part of such a diverse partnership of interests.

The project area stretches from the west coast of Scotland to Loch Ness, encompassing multiple Glens including Glen Affric, Cannich, and Moriston. What was the process behind selecting this area for this project?

One of the earliest aspirations of Trees for Life was to realise the potential for Glen Affric to act as a coast-to-coast habitat corridor, noted I believe by George Peterken in the 1980s. However, as the idea grew in our minds, we knew we wanted to try for a big area to get the ecological multiplier effects that come from genuine landscape-scale change. We also know that the potential here is massive, with a diverse range of woodlands, peatlands, freshwater, montane, riparian, and coastal habitats all capable of restoring themselves. If we can increase the ecological connectivity at this scale, potentially 2000 sq km, the wildlife response that follows will be tremendous and importantly, resilient over the longer term.

Of course, all of that is little more than a daydream if we fail to bring the communities and landowners with us. Our key priority at this stage is to show people that a high level of ambition for the natural environment can positively impact their ways of life.

Have you found the Covid-19 pandemic has affected the development of this project? How have you coped with the challenges of the current situation?

It’s been both good and bad. It has caused us problems as we’ve been trying to reach out and build new relationships without the spontaneity and informality of face-to-face conversations. However, as we all got our heads around online meetings, we’ve benefited from the speed at which we can meet people and reduced the need to spend time travelling. Hopefully, as we get to the point of starting the initiative in earnest this autumn, we’ll have the scope to meet people in person, which will undoubtedly help the partnership to become genuinely co-creative.

For anyone who is inspired by the vision of Trees for Life and wishes to help, how would you recommend they get involved?

You can learn more about Trees for Life and our vision for a rewilded Scotland by visiting our website.

We hope that our volunteer programme will restart in spring 2022. This includes our popular Conservation Weeks. People should keep an eye out for updates on our website and social media channels.

We have a Cycle for the Climate initiative, where people can raise money for rewilding through bike challenges – both big and small. And of course, we are forever grateful to people who choose to make regular and one-off donations to the charity. This is what we depend on to plan future projects and keep building towards a rewilded Highlands where people and nature enjoy a better relationship.

Author Interview: Collins Birds of the World

Collins Birds of the World is the complete collection of Norman Arlott’s beautifully detailed and accurate bird paintings, brought together for the first time. Accompanied by text detailing characteristics and appearances for each species, this comprehensive new field guide is the ultimate reference book for birdwatchers and bird lovers.

Norman Arlott is a wildlife artist and has illustrated over 200 books. He has kindly answered some of our questions on his experiences and the process of creating this all-encompassing work.

Could you tell us about your background and what inspired you to become a wildlife artist?

I originally trained as a mechanical engineer but ‘jumped ship’ in the 70s to take up my real love as a wildlife artist, with a focus on birds. I made this leap with much encouragement from my wife Marie and a great deal of help and inspiration from well-known bird artist Robert Gillmor, bird photographer Eric Hosking and the great East African ornithologist John Williams. I had no intention of working on book illustrations, but I got caught up in it, really liked it and I have enjoyed it ever since.

In the intervening years, I have contributed illustrations to over 200 books, including some classics such as Birds of the Western Palearctic, Handbook to the Birds of the World and the SASOL Birds of South Africa. Many postage stamps feature my artwork from places such as Jamaica and The Bahamas in the Caribbean, Liberia in Africa and Fiji in the Pacific Ocean.

Over the last 15 years, I have concentrated mainly on writing and illustrating a series of bird guides (more coloured checklists really) covering the Palearctic, India, The West Indies, North America, South East Asia and the Philippines – many of these illustrations and accompanying text feature in the forthcoming Birds of the World.

You’ve been a part of creating bird guides for areas as broad as the Palearctic to more specific locations such as the Indonesian Archipelago and Armenia. What have you enjoyed most about your travels?

During the last 40 years or so, I have had the good fortune to travel to various parts of the globe, most notably East and South Africa. I led safaris to Kenya and Tanzania for many years, which led to many adventures and meetings. On one of my first visits, I was fortunate to form a friendship with two people: author and broadcaster Roger A Caras and zoo director Steve Graham, enabling me to visit North America. Whilst in America, I was introduced to many of my bird-artist ‘heroes’, all of which passed on great encouragement and useful tips – one snippet passed to me by the great Arthur Singer was always to remember ‘white areas are equally as important as the illustrated areas in the look of a plate’.

When illustrating Antpittas for the Handbook of the Birds of the World, you were integral in the realisation that a specimen in the Natural History Museum was misidentified. Could you tell us more about this experience?

The Antpitta discovery came about after a research visit to the British Museum at Tring. Needing to find a reference for the Yellow-breasted Antpitta, a bird I was about to illustrate for the Handbook to the Birds of the World, I was able to photograph and make notes from the one and only skin in the museum. Before embarking on the illustration I checked the text notes provided by the authors only to discover that the text and the bird I had photograph did not correspond. My initial thought was I had photographed the wrong specimen so I called Robert Prys-Jones at the British Museum and asked him to check the skin – Robert, along with Peter Salaman, then followed up my query and came to the conclusion that the specimen in the British Museum was in fact a new subspecies of the Brown-banded Antpitta. All the relevant details of this new bird can be found in the Bulletin of the British Ornitholgists’ Club (Vol 129-1). I have made many visits to the British Museum to do research for various books and this is the only time I have known a skin to be completely misidentified, especially a skin with a label annotated by P. L. Sclater, an expert on the family.

Collins Birds of the World is a huge, comprehensive collection of over 25,000 illustrations of 10,711 species. Could you tell us a little bit about the process of creating this guide?

I was asked to consider putting together a complete coloured checklist to the Birds of the World using the vast Harper Collins artwork archive. There were a few areas that Harper Collins did not have suitable artwork, such as Australia, New Guinea and some small island groups, so I painted all of these in readiness for putting together the Birds of the World plates.

I decided that to even start this project, a standard ‘list’ was needed – it was decided that the International Ornithological Congress (IOC) world list as of January 2019 was the one I would rigidly follow. Using mainly mine and Ber Van Perlo’s artwork, I promised Harper Collins that I was able to put together the 301 plates and hopefully make a really satisfying (to look at) book, even though some of the plates may contain a great number of species.

Although told by many that I was an ‘idiot’ to take on such a project, and I admit at times I had to agree, overall I genuinely enjoyed the experience of working ‘electronically’ to produce plates. Hopefully, I fulfilled the promise I made to the publisher to produce an attractive and practical book to the Birds of the World!

After my work designing the plates, David Price Goodfellow and his team went on to produce the high-resolution scans and add any missing pieces of text, so all in all a great team effort.

After such a mammoth publication, do you have any more projects lined up for the future?

I have recently been given the opportunity by Harper Collins to produce a large-format book of my ‘proper’ paintings of British birds – what a difference from the past couple of years.

The NHBS Guide to UK Owl Identification

There are six owl species in the UK, although only four are native (barn, tawny, long-eared and short-eared owl). We also get occasional visitors, such as the snowy owl (Nyctea scandiaca).

Owls are mainly nocturnal and feed on predominantly small mammals such as the field vole (Microtus agrestis), but also some small birds, invertebrates, amphibians and fish. All these species are listed as ‘least concern’ by the IUCN red list but face serious threats in the UK, such as habitat loss, declining prey populations and a decrease in nesting sites, as well as direct deaths such as from car collisions or poisoning. Owls can be used as an indicator species for the health of the food chain: their decline may indicate that other wildlife that also depend on the same habitats are also under threat.

Identification of owl species usually relies on colouration and eye colour, as well as their call. This is particularly important as owls are often active at night and therefore are hard to identify by sight.

There are several types of equipment that can be useful when searching for owls, such as binoculars, night vision monoculars, a headlamp or flashlight and a guide to owl pellet identification. If you wish to encourage owls onto your land, there are a variety of nest boxes available, depending on the species you wish to attract.

Little Owl (Athene noctua)

Distribution: Widespread throughout England and parts of Wales. Rare in southern Scotland
What to look for: The little owl is a small species, with brown and white feathers in a dappled appearance. It has a short tail and bright yellow eyes. Usually out at night, it is most likely to be seen perched on structures such as trees, telegraph poles and fences.
Did you know? The little owl is non-native in the UK and was introduced in the late 1800s. It is not thought to cause any detrimental impacts on any other species.

Barn Owl (Tyto alba alba)

Distribution: Widespread across England and Wales, with decreasing density towards north Scotland and scattered distribution in Ireland
What to look for: An iconic species, the barn owl is instantly recognisable. Its silver and golden-brown back and pure white underside and face are distinctive, along with its heart-shaped face and black eyes. Its face shape plays an important function for hunting, as it directs high-frequency sound to their ear openings, such as those produced by mice and voles. This helps the barn owl to perform precision hunting in tall vegetation. Another subspecies, Tyto alba guttata, which has a darker coloured underside, also occurs in the UK.
Did you know? Owing to their large wing size compared to their body mass, and the structure of their feathers, barn owls fly almost completely silently.

Tawny Owl (Strix aluco)

Distribution: Widely distributed in England, Wales, and parts of Scotland, but not in Northern Ireland
What to look for: The tawny owl has mottled brown feathers with flecks of white and more reddish-brown. Its colouration can vary from brown to grey. This species has a paler underside and a round head, with large black eyes and a dark ring pattern around its face.

Long-Eared Owl (Asio otus)

Distribution: Widespread across the UK, although fewer individuals in Wales and south west England.
What to look for: This mottled brown species has bright orange-red eyes and long tufts that resemble ears, hence the common name. The long-eared owl is a shy, nocturnal species that can be found in communal roosts in densely covered woodland and forests. The population is boosted in winter due to numbers of migrating individuals from other parts of Europe.

Short-Eared Owl (Asio flammeus)

Distribution: Migratory species, found across Scotland and northern England in summer before moving further south during winter.
What to look for: Often confused with the long-eared owl, this species is slightly slimmer, with a paler colour and yellow eyes rather than the long-eared owl’s orange. It has brown feathers on its back and a pale belly, with darker feathers framing its eyes. They also rarely display their ‘ear’ tufts.

Eurasian Eagle-Owl (Bubo bubo)

Distribution: Very rare, scattered around the north of the UK, including Lancashire, Greater Manchester, Galloway, and Inverness-shire.
What to look for: The Eurasian eagle-owl has tufts similar to the long-eared owl. It is a large bird, weighing up to 4.6kg compared to the barn owl at 500g. This species is mottled, but there is a high variation in plumage colouration for this species, from browny-black to a pale grey. There is often a dark band running from the eye to the ends of the ‘ear’ tufts. It may have pale sections around the eyes and beak, with a darker, splotched forehead.
Did you know? There is serious debate surrounding this owl species and its place in the UK countryside. While there is fossil evidence that suggests this species inhabited the UK before becoming extinct, many don’t believe it is a native species. Therefore, the conservation of this species and the safety of the individuals present in the UK is under threat.

The NHBS Guide to UK Bird Nest Identification

The main breeding season for birds in the UK is between March and August every year. This article looks at some of the various bird nests built by UK species.

What are they made of?

Not all birds build nests, but those that do use a huge variety of materials, depending on the nesting time, the species and surrounding habitat. They can contain tightly woven twigs, grass or woody stems. Other species use premade nooks and crevices in trees, natural structures or buildings. Nests can be lined with softer or warmer materials such as animal fur, moss, mud or feathers. These materials are usually held together by spider webs, twine-like vegetation or even horsehair.

Nest varieties

Nests can be a variety of sizes, depending on the size of the bird, the need to remain hidden and the structural limitations. For example, the largest recorded bird’s nest is a bald eagle (Haliaeetus leucocephalus) nest at 2.9m wide and 6m deep. It was recorded in 1963 in Florida, USA. In Scotland, a golden eagle (Aquila chrysaetos) nest was recorded in 1954 at an impressive 4.57m deep. The smallest recorded birds nests are made by hummingbird species, around 2cm wide and 2-3cm tall.

How are they built?

The nests can be built by either the male or female, or they can work together. They can take from a few days to a few weeks to build, depending on the size and complexity. Some bird species build a new nest every breeding season but others, such as the goshawk (Accipiter gentilis) will use the same nest for many years.

Identification

Often enough, if you observe a nest from a distance, you’ll be able to identify the species when the adult birds return. But there are other ways to identify the owners of a nest. Nest size, shape, material and placement can all be useful ways to identify them, as well as egg size, number, colour and pattern. Some nests and eggs are so similar, however, they can be very difficult to identify in the field. Nests and eggs are protected by law through the Wildlife & Countryside Act 1981; it is an offence to take, damage or destroy any wild nest. Disturbance can lead to young being abandoned and injury to nesting birds – please observe nests from a safe distance.

Location and timing can also be important, as not all bird species nest at the same time and some only nest in certain ranges within the UK. Many species can also be quite specific about the habitat they nest in.

Nests are usually categorised by type and those in the UK can include:

Scrapes

These are nests of the simplest construction, usually a shallow depression in the sediment or vegetation. They can sometimes be lined with vegetation, stones, feathers or shell fragments, often to help camouflage the eggs. This is a common nest type of many wader species, as well as pheasants, quails and bustards.

Ringed Plover (Charadrius hiaticula)

The ringed plover breeds on open ground, such as beaches and gravel flats. They lay their eggs directly on the ground in an open area with little or no vegetation, with shell fragments sometimes used to line the nest. They usually produce 2-3 clutches per breeding season, each with up to four eggs. These eggs are pale brown with dark brown speckles. As this nest type is very vulnerable to predators, the ringed plovers have developed a strategy to draw attention away from the eggs – the parent bird will lead a predator away from the nest by feigning an injured wing.

Oystercatcher (Haematopus ostralegus)

This species also creates scrape nests, although they can be lined with twigs or other vegetation. Laying between 1-4 eggs, only one clutch is laid per season. The eggs are similar to the ringed plover, with a pale brown background and dark brown speckles. This species, however, uses a practice called ‘egg dumping’, where they lay their eggs in a nest of another species, such as herring gulls, and allow them to raise the chicks.

Burrow

These are nests dug into the ground, riverbanks or cliffs. The UK birds that nest in burrows include puffins, some petrel and shearwater species, sand martins, shelducks and kingfishers. Many burrow-nesting birds excavate their own burrows but some use the pre-dug burrows of other species. Puffins, for example, often use empty rabbit burrows. As these nests are underground, species identification can be difficult without disturbing the nest, therefore it is best to wait for an adult bird or chick to appear. The location of the nest can also help to identify the species. Kingfishers, for example, usually occupy burrows in riverbanks.

Puffin (Fratercula arctica)

The Atlantic puffin lays a single white egg between late April to early May. The parent birds will defend the nesting site and take turns feeding the chick until it is ready to fledge, between 34-60 days after laying. During this time, the chick will remain within the nest burrow.

Cavity

Cavity nests are chambers, usually in trees. They can be excavated by the bird themselves, such as woodpeckers, but most species use natural cavities or disused nests. These species are often enticed to use nest boxes as these mimic natural cavities. The process of excavating a cavity can take, on average, around two weeks.

Eurasian Nuthatch (Sitta europaea)

The nuthatch does not create its own cavity and will often use old woodpecker nests, although they will enlarge an existing hole or, if the entrance is too large, the female will plaster it with mud to reduce the size. The nuthatch lays between 6-9 white eggs that have red speckling. The eggs are small, usually around 2cm long and 1cm wide.

Cup

A cup nest is a hemispherical nest, with a deep depression for the eggs to be housed in. It is often made of a more pliable material such as grasses and thin twigs, but some can be made of mud. These nests are built mostly by passerine birds.

Blackbird (Turdus merula)

Blackbirds usually build their nest in evergreen bushes such as ivy, hawthorn or holly, but will also nest in sheds and outbuildings. The nest is built by the female and made with vegetation such as leaves and grass, bound together with mud. The female lays 3-5 bluish-green eggs with reddish-brown blotches that are, on average, 2.9cm long and 2.1cm wide.

Song Thrush (Turdus philomelos)

This species builds a mud-lined cup nest, usually in bushes or trees. The song thrush lays between four to five eggs, which are blue with dark spots and are around 2.7cm in length and 2cm in width. They can lay between 2-4 clutches per season.

Platform

These nests are large structures, which can either be elevated or on the ground, depending on the species. They can often be much larger than the bird that built them. This nest type is often used by birds of prey, but also by other birds such as herons, cormorants, and grebes.

Great Crested Grebe (Podiceps cristatus)

Some waterbird species build nests directly on top of the water. These floating platform nests are built out of aquatic vegetation, cattails, reeds and mud. They can be anchored to vegetation to keep them from drifting away and to conceal them from predators. The great crested grebe usually lays four chalky white eggs, which are around 5cm in length and 3.7cm in width.

Osprey (Pandion hallaetus)

Usually breeding near freshwater, the osprey creates large platform nests made out of sticks, turf, driftwood or seaweed. They can be built on rocky outcrops, artificial platforms, forks in trees or even utility poles. The nests can be as wide as two metres. Osprey usually lay 2-4 whitish eggs with reddish-brown splotches. The eggs are quite large at 6.2cm long and 4.5cm wide.

Sphere

A few UK species create sphere nests, round structures that are completely enclosed apart from a small entrance opening. The entrance is usually on the side as it allows for protection from the rain. These nests can be made from mud, vegetation, or woven twigs and are commonly covered on the outside with moss, lichen or other camouflaging vegetation.

Long-tailed Tit (Aegithalos caudatus)

These nests can be identified by shape but also by construction material. The long-tailed tit uses lichen, feathers, spider egg cocoons and moss to create its nest. The nests are usually suspended in gorse, bramble bushes or high up in tree branches. The lichen is usually used to line the outside as camouflage and the feathers line the inside as insulation. The long-tailed tit has one brood per season and lays between 6-8 eggs, but can lay as many as 15. The eggs are white with reddish-brown speckles.

Climate Challenges: What is COP26 and Why is it Important?

In the lead up to 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. But what exactly is COP26?

COP26 is the 26th annual summit of the United Nations climate change conference, taking place in Glasgow from 31st October to 12th November 2021. The Conference of Parties, known as COP, is responsible for monitoring and reviewing the United Nations Framework Convention on Climate Change (UNFCCC) and its implementation. The UNFCCC is an international treaty acknowledging the existence of anthropogenic climate change and provides the framework for climate change negotiations.

Over 190 world leaders, along with thousands of government representatives, businesses, negotiators and citizens, will convene in Glasgow, Scotland, to update plans for reducing emissions. During these summits, countries set out Nationally Determined Contributions (NDCs) to commit how much they will reduce their emissions. COP26 was delayed by a year due to the COVID-19 pandemic, but this year there will be updated plans for the global reduction of greenhouse gas emissions. Suggested to be one of the most important climate crisis summits ever, COP26 must be divisive to limit global temperatures exceeding 1.5°C above pre-industrial levels ahead of the approaching 2030.

The history

The convention began in 1992 during the ‘Earth Summit’ in Rio de Janeiro. The UNFCCC treaty was adopted two years later and has been ratified by 197 countries. The COP began meeting each year from 1995, to review the implementation of the UNFCCC and amend commitments and targets. This will be the first time the UK has hosted the COP.

In 2010, countries committed to limit the global average temperature increase to a threshold of 2°C compared to pre-industrial levels by signing the Cancun Agreements. Further research and several reports from sources such as the Intergovernmental Panel on Climate Change (IPCC) showed that to avoid extreme impacts of climate change, the target should be 1.5°C. Thus, the Paris Agreement was created and entered into force in 2016. In 2018, the IPCC released its Special Report of Global Warming of 1.5°C, bringing together the findings of multiple climate scientists to present the steps needed to maintain global average temperature rise below 1.5°C.

What does ‘1.5°C’ mean?

The 1.5°C pledge is the goal of the Paris Agreement to limit global warming to below 1.5°C compared to pre-industrial levels, with an upper limit of 2°C. This is an increase in the Earth’s average temperature, measured from a baseline average temperature between the mid-to-late nineteenth century, during the Industrial Revolution. The impacts of higher temperatures are already being felt, but it is thought that an increase above 1.5°C will be the tipping point for many natural systems.

An increase above 2°C could lead to:

Severe heatwaves at least every five years for around 1.7 billion more people
Several hundred million extra people exposed to poverty and other climate-related risks
An average sea rise of another 10cm
It could also cause coral reefs to decline as much as 99%
A decline in global fishery catches by another 1.5 million tonnes
18% of insect species could be lost, along with 16% of plants and 8% of vertebrates
More erratic rainfall, with more intense rain on days it does fall, leading to up to 79 million people being exposed to the risk of flooding
Water stress will increase, with more frequent and longer droughts. Certain countries will see a significant drop in groundwater, and therefore a drop in productivity in crop and livestock farming
There may be an expansion in the range of malaria-carrying mosquitoes, increasing malaria transmission by 120%

The process

There is a long road to COP26, which started in December 2020 with the Climate Ambition Summit, co-hosted by the UN, UK and France. 75 world leaders announced new commitments. The next stage was the Climate & Development Ministerial in March 2021, where the challenges and priorities of implementing the Paris Climate Agreement were discussed.

In April 2021, the Leaders Summit on Climate took place with 40 world leaders, convened by President Biden. Ambitious commitments were made by the US and Japan to reduce emissions by 2030. All members of the G7 were committed to net-zero by 2050.

In May and June 2021, five events took place:

Petersberg Climate Dialogue,
P4G Seoul Summit,
12th Clean Energy Ministerial (CEM) – 6th Mission Innovation Ministerial,
the UN Climate Change Conference – Sessions of the Subsidiary Bodies,
and the G7 Leaders Summit.

These all involved working to accelerate negotiation progress, developing public-private partnerships, promoting policies, and uniting leading democracies, to promote a greener future ahead of COP26.

Between July 26th and 6th August, the Fifty-Fourth Session of the Intergovernmental Panel on Climate Change (IPCC-54) and Working Group 1 Assessment Report 6 Approval Plenary takes place, providing key inputs from the Sixth Assessment Report into the negotiations at COP26.

In September 2021, four events will occur:

76th Session of the UN General Assembly (UNGA)
Climate Week NYC
Youth4Climate: Driving Ambition
Pre-COP26

These involve the discussion of the challenges of recovering from COVID-19, a chance to showcase climate action, and allowing 400 young people (between 18-29) to discuss negotiations. The Pre-COP26 is mainly a preparatory meeting, involving the discussion of key political aspects of COP26 negotiations, and a chance to find solutions for any outstanding issues.

During October 2021, there will be:

UN Biodiversity Conference,
Global Investment Summit: Building A Green Future Together,
World Bank Group/International Monetary Fund Annual Meetings,
G20 Leaders’ Summit.

These final events discuss the action needed to reverse biodiversity loss, the investment opportunities of net-zero across the UK, and the representation of shareholders on the world economic outlook and other issues. Finally, shared challenges between G20 countries are addressed, focusing on recovering from the pandemic and addressing climate change.

COP26 begins immediately after the conclusion of the G20 Leaders’ Summit in November.

General goals:

The general goals of COP26 are to:

Secure global net-zero by mid-century and keep 1.5 degrees within reach
Adapt to protect communities and natural habitats
Mobilise finance
Work together to deliver

To achieve these, countries must quickly phase out coal, reduce deforestation, increase the speed of the switch to electric vehicles, and encourage investment in renewables. To adapt better, counties must protect and restore their ecosystems, and increase defences, resilient infrastructure and effective warning systems to avoid loss of lives, homes and livelihoods. Developed countries must mobilise at least $100bn (£71.7bn) in climate finances per year, with international financial institutions playing their part. Finally, the Paris Rulebook (a set of rules to make the Paris Agreement operational) must be finalised and there must be an acceleration in action to tackle the climate crisis, especially through the collaboration of governments, civil society and businesses.

UK goals

The UK government announced in November 2020 a £12billion government investment towards a 10 point plan:

Advancing offshore wind
Driving the growth of low carbon hydrogen
Delivering new and advanced nuclear power
Accelerating the shift to zero-emission vehicles
Green public transport, cycling and walking
‘Jet zero’ and green ships
Greener buildings
Investing in carbon capture, usage and storage
Protecting our natural environment
Green finance and innovation

There are some success stories in the UK’s fight against climate change, with emissions down 49% since 1990, with the strongest record in reducing emissions over the last decade in the G20. We are the world leaders in offshore wind energy, with the power sector only accounting for 13% of all territorial emissions within the UK. Our Climate Change Act of 2008 was the first of its kind.

There has been little progress in cutting emissions outside of the energy sectors, however, stifling our process to achieving the ambitious targets of a 78% reduction by 2035. Further plans, such as airport and road expansions and new oil and gas exploration within the North Sea, undermine the UK’s position as one of the leaders in the fight against climate change.

One key pledge is to protect 30% of the UK for nature by 2030. When it comes to the number of species that have been lost, the UK ranks bottom among the G7 countries and is in the lowest 12% of 240 countries and territories. In 2019, it was reported that 41% of species within the UK were in decline and it is estimated that only 5% of the land is considered healthy habitat.

Summary

COP26 is a summit of the United Nations climate change conference, responsible for monitoring and reviewing the UNFCCC and its implementation.
The aim is to limit the increase in global average temperatures to below 1.5°C (with an upper limit of 2°C)
The road to COP26 involves 17 summits, conferences, and meetings over 11 months, leading up to the COP26 event hosted by the UK in November
The UK government has made advances and big promises to tackle climate change, but certain plans are undermining their efforts and may be setting the wrong example ahead of COP26.
