The Welsh Government is urging bird keepers across the country to act now to protect their flocks against avian influenza this winter.

Every bird keeper in Wales, whether they keep a few pet birds or a large commercial flock, should act to protect their birds now, not wait until the risk increases, say government officials.

Keepers are asked to review their biosecurity, complete a self-assessment checklist, and build good practice into their daily routine.

Clinical signs of avian influenza, commonly known as bird flu, may include a swollen head, blue discolouration of the neck and throat, loss of appetite, respiratory distress, diarrhoea, a drop in egg production, and increased mortality.

Bird keepers who suspect avian influenza in their flock must contact the Animal and Plant Health Agency (APHA) immediately on 0300 303 8268.

Chief Veterinary Officer for Wales, Dr Richard Irvine, said: “Don't wait until the risk increases – the time to act is now. Check you have strict hygiene and biosecurity in place at all times as this is the single most effective way to protect your birds from avian influenza.

“Simple, consistent measures, such as keeping bird areas and housing clean, limiting unnecessary visitors, and preventing contact with wild birds, all help reduce the risk of disease getting in.

“I want to thank the bird keepers across Wales who remain vigilant and report any suspect signs of disease promptly to APHA. Your continued attention to biosecurity plays a vital part in protecting flocks across the country.”

Bird flu restrictions in Wales were lifted over the summer after being in place for 18 months following outbreaks in various parts of Wales.

Mandatory biosecurity measures for poultry and other captive birds were introduced in January 2025 to help prevent the spread of avian influenza from wild birds or any other source.
