We appreciate the concern around protecting our precious wild birds, and the government is looking carefully at how the issue can be addressed.

The primary legislation protecting wild birds and their nests in England and Wales is the Wildlife and Countryside Act 1981. All wild birds’ nests, with some limited exceptions in extraordinary circumstances, are fully protected and it is an offence to destroy them while they are in use or being built.

Birds which habitually use the same nests, white-tailed eagles, ospreys and golden eagles, have their nests protected year round, even when not in use.

In the case of swallows, swifts and martins, nests will remain in use throughout the summer until the birds leave on their autumn migration. They may return to the same sites for nesting, but these birds can and will, nest elsewhere. That is why the priority is to protect the nests while they are in use.

All local authorities have a duty to have regard to conserving biodiversity as part of their policy or decision making. As well as this duty, national planning policy states that the planning system should minimise impacts on biodiversity and provide net gains in biodiversity where possible. Specific biodiversity features, such as swift bricks, would normally be required of developments through either the relevant local plan or through the local authority’s development control team.

We want developments to enhance our natural environment, which is why we have announced plans to require developers to deliver a ‘biodiversity net gain’. This means that habitats for wildlife must be left in a measurably better state than they were before any development.
