Unusual bird behavior and illness observed across species on Yukon Delta
"Since about May 25, crews have been seeing multiple species showing what we believe are signs of highly pathogenic avian influenza. The signs we are seeing widespread is a headshaking that we equate to "getting the cobwebs out", like a person may do when they first wake up. This behavior occurs regularly every couple minutes. This behavior has been observed in: black brant, cackling geese, bar-tailed godwits, dunlin, lapland longspurs, spectacled eiders, emperor geese, greater white-fronted geese, sabines gulls, glaucous gulls, and red-necked phalaropes."
