(Boston) Wildlife authorities in Maine said six wild ducks found dead in a stream in Winthrop have tested positive for bird flu.
The hooded mergansers were found dead in Mill Stream and tested positive for a highly pathogenic avian influenza, the Maine Department of Inland Fisheries and Wildlife said Friday.
The wildlife department said the National Veterinary Services Laboratories in Iowa confirmed the strain to be the kind circulating in Maine. The department said the strain is highly contagious and can spread and mutate between wild and domestic flocks of birds.
