Race to contain suspected bird flu outbreak among Thames Valley swans

Volunteer workers say increasing case numbers and dozens of dead birds raise fears spread is wider than recorded

Members of the public and charity volunteers are working to contain a suspected outbreak of bird flu among swans in the Thames Valley, amid signs that confirmed cases are continuing to rise.

Since October, 324 cases of bird flu in swans have been recorded by the Animal and Plant Health Agency (Apha), which is sponsored by the Department for Environment, Food and Rural Affairs (Defra). Of these, 39 were recorded in the first four weeks of 2026 alone.
