The Alderney Wildlife Trust said the sea bird colony is still recovering from the 2022 outbreak

Bird flu has killed an estimated 30% of Alderney’s gannet colony, The Alderney Wildlife Trust has said.

The Trust believed the population had “not recovered” from an avian influenza outbreak in 2022 which killed hundreds of the sea birds.

Experts from the Trust initially thought the remaining gannets would recolonise the islands in 2023.

The Trust’s Paul Belben said the speed of recovery was not a complete “surprise”.
