Answer
All birds are protected under the Wildlife and Countryside Act 1981. This Act makes it illegal to cause harm or suffering to any bird, or to damage/destroy nests, eggs, or chicks. Some species of birds are afforded extra protection under the Act, prohibiting any disturbance whatsoever.
For more information relating to the laws protecting particular species of bird, you should contact the Royal Society for the Protection of Birds (RSPB). A link to the RSPB website is listed in related information.
If you think a wildlife crime is being committed you can report it to your local Police Wildlife Crime Unit or by calling 101.
You can also report wildlife crime anonymously to Crimestoppers .
