A bald eagle found at Southaven County Park in Brookhaven was humanely euthanized due to concerns about a huge spread of highly pathogenic avian influenza, or bird flu.

Staff at the Evelyn Alexander Wildlife Rescue Center in Hampton Bays say they are waiting for the official test results to confirm whether the eagle had avian flu, but it was showing signs associated with the disease. The bird had multiple seizures, fell off a tree and was making loud screeching sounds.

Animal experts say avian flu is affecting birds such as gulls, loons and snow geese on Long Island.

They are advising anyone with birds at home to be more cautious when it comes to their interaction with other birds.

"What we do know about avian flu is it's wiped out farms of domestic fowl, and so that is the scary part about the convergence between our wild birds and our domestic birds," says Jessica Chiarello of the Evelyn Alexander Wildlife Rescue Center.

A representative with Northwell Health tells News 12 there have been no reported or suspected cases of avian flu in humans at any of their emergency departments.

The Centers for Disease Control and Prevention also say there have been no reported human cases of bird flu anywhere in the U.S.
