According to the USDA, at least 48 bald eagles (Haliaeetus leucocephalus) have died from H5N1 highly pathogenic avian influenza (HPAI) since February.  The eagles acquire infection from scavenging on dead or captured waterfowl.  There is no treatment for avian influenza which manifests in the species as incoordination and inability to fly.  Affected birds have been euthanized. There is no report of attempts to administer antivirals.

In past years, epornitics of HPAI have spared most non-domestic avian species.  With regard to H5N1 during 2021 and 2022, the infection has resulted in severe losses in over 50 species including cranes, swans, hawks, pelicans, crows, barnacle geese and cormorants on three continents.
