A nest is a structure or place made or chosen by a bird for laying eggs and sheltering their young. There's a lot of variation in the types and location of nests created by birds who live in or migrate to and from Britain.
In England and Wales - all wild birds, their young, nests and eggs are protected under the Wildlife & Countryside Act 1981.
Different types of nests and where they are found
Nests vary greatly from intricate structures built of materials such as twigs, moss, grass, mud and feathers, to simple twig platforms. Some species don't even use nesting material.
Some birds nest in trees and others on the ground
Cup-shaped woven nests are typically found in trees and bushes. Some species such as blue tits, ducks and owls use tree cavities, and others such as the grey partridge even nest under hedges.
Lots of species nest on the ground in locations from heathlands to coastal regions, with nests and young carefully camouflaged. Some species build nests and others use simple scrapes in the ground.
Cliffs and sand dunes are not just used by seabirds, species such as swifts will nest in the cavities of rock faces. Puffins even use disused rabbit burrows on cliff-top nesting sites.
Nests in buildings
Buildings are used as nesting sites by many species, including swifts which nest under the eaves of buildings. Species such as pigeons and some gulls also commonly nest on building roofs.
When baby birds are born
In the UK, birds usually breed in the spring and summer. However, species such as crossbills may lay eggs as early as January to coincide with food availability (pine seeds), and pigeons and doves are known to nest all year round. Factors such as unusually warm weather may also trigger birds to begin nesting early, and many species will lay more than one clutch of eggs during the breeding season.
For some species, nests can also provide important sites to roost in at other times of the year. For example, over a dozen wrens might congregate in a nest for shelter on a winter's night. Some species also reuse their nests the following year or reuse old nests of other species.
Birds and their nests are protected by law
All wild birds in England and Wales are protected under the Wildlife & Countryside Act 1981. It's an offence under the Act - subject to certain exceptions (such as the control of a species for permitted reasons under licence) - to intentionally take, damage or destroy the nest of any wild bird while that nest is in use or being built.
It's also an offence, except under licence, to take or destroy an egg of any wild bird or to kill, injure or take a wild bird or their young.
For over 80 species of birds (such as barn owls, bitterns, kingfishers and goshawks) listed in Schedule 1 of the Act, it's also an offence to intentionally or recklessly disturb them:
- while they are building a nest
- in or near a nest containing eggs or young
- or to disturb their dependent young.
Additionally, for species included in schedule ZA1 (birds which reuse their nests), which includes ospreys, golden eagles and white-tailed eagles, it's an offence to intentionally take, damage or destroy their nests even when they're not in use.
If you find a dead bird in your garden, please report it to the Garden Wildlife Health Project.
How to help nesting birds
There are hundreds of different species of wild birds that breed regularly in the UK. Some bird populations - such as house sparrows and starlings in urban areas - are declining, partly as a result of the loss of nest sites.
You can help nesting birds by:
- Making buildings bird-friendly by providing nest sites, such as 'swift bricks' built into walls that swifts will make their nests in.
- Making gardens bird-friendly by providing nest sites and boxes, and planting trees or bushes so that birds can use the leaves or twigs as nesting materials.
- Not cutting down trees and bushes in the spring and summer, but waiting until autumn and winter once the breeding season has finished.
- If you see fledgling birds in your garden, keep pets indoors for a few days until the young birds get the hang of flying.
- Providing food and water sources for birds
