The purpose of this document is to bring together in one location some of the more informative Web sites having information specific to avian influenza in wild birds. Avian influenzas of many different strains have long been known to occur naturally in wild birds, particularly waterfowl and shorebirds. These viruses normally circulate in wild bird populations, but rarely cause mortality. Long a focus of concern by the poultry industry as a source of influenza infections in domestic stock, the influenza strains that infect wild birds was not known to infect humans until recently. Since 1997, the highly pathogenic H5N1 avian influenza virus has emerged as a source of mortality in wild birds, domestic poultry, and humans in southeast Asia. The precise roles played by migratory birds in the spread of H5N1 and its transmittal to domestic poultry and humans remain uncertain and continue to be debated by experts.

If you reference only one of the links below, we suggest that you make it the National Wildlife Health Center’s Avian Influenza Home Page, which we consider to be the premier online source for information on avian influenza in wild birds.

To make navigation of this site easier, links to avian influenza in wild birds are organized in six categories:
