Avian Influenza Geonarrative

The USGS Ecosystems Mission Area provides science to understand wildlife diseases, including avian influenza (AI). Avian influenza viruses occur naturally in wild birds such as ducks, geese, swans, and gulls. These viruses generally do not cause illness in wild birds but they can be highly pathogenic and cause illness and death in poultry and wildlife. Learn more with this geonarrative.
