The migration chronology of banded mallards might be broadly representative of other dabbling duck species that breed in Alaska, such as the American green-winged teal
(Anas carolinensis), American wigeon (Anas americana), and northern pintail (Anas acuta), in which H5Nx was detected at lower latitudes.
Some are transient visitors such as the American green-winged teal
, the lazuli bunting and the belted kingfisher.
Serum samples from blue-winged teal, American green-winged teal
, and mallard ducks were screened by using blocking ELISA (FlockCheck AI MultiS-Screen antibody test kit; IDEXX Laboratories, Westbrook, ME, USA) to detect antibodies against the influenza virus nucleoprotein.
