LYNDEN, Wash. – Almost 400 sick or dead birds have turned up near Wiser Lake in Whatcom County and the public is being warned to stay away from them.

The County Health Department and Washington State Department of Fish and Wildlife say many of the birds have tested positive for a highly infectious bird flu.

The illness is spreading among wild birds and has been found in backyard flocks in western Washington.

You should stay away from dead birds and keep pets from contacting them.

Do not try to transport sick birds to a vet or for any other reason as they could spread the virus to uninfected areas.
