Hundreds of dead cormorants wash up on Martha's Vineyard as officials warn of bird flu

Hundreds of dead birds have washed up on Martha's Vineyard and animal control officials there think a highly contagious strain of avian flu may be responsible.

The Tisbury Animal Control posted an "avian influenza warning" on social media Monday, telling residents that hundreds of dead cormorants have washed up all over the island and it's "extremely dangerous" for a small island.

Animal control officers collected the birds and sent many to the Massachusetts Division of Fisheries and Wildlife for testing.
