Details

This report is produced by the Animal and Plant Health Agency (APHA). It is updated regularly with findings of highly pathogenic avian influenza (HPAI) – often referred to as bird flu – in wild birds in Great Britain. Updates are recorded in calendar weeks (for example, week 1 is the first week in January).

These are findings of avian influenza from our ongoing routine surveillance for avian influenza in wild birds. This surveillance is made up of patrols by wild bird reserve wardens and collections of found-dead wild birds reported to us by members of the public. This data only represents cases where birds have tested positive for avian influenza.

Find out when to report dead wild birds and how to report them.
