Samples being sent to UK for testing
People are asked not to touch sick or dead birds after a significant number were found washed up on beaches in the Isle of Man.
More than 20 carcases have been collected by government vets since the first finding on Fenella Beach, in Peel, last Thursday.
The dead birds, which are mainly guillemots, have also been found at Fleshwick, Spaldrick, Niarbyl and Kirk Michael with further reports in Port Erin and near the Calf of Man.
Last month bird flu was confirmed at some of the UK's seabird colonies at Bass Rock in Scotland, the Farne Islands in northeast England, and the Norfolk coast, so samples have been sent to the UK for testing.
