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.
