Avian Influenza and Waterfowl

USGS scientists are studying avian influenza to understand how the virus spreads through and affects wild waterfowl populations. By tracking waterfowl movements and monitoring infection patterns across species, USGS research reveals which species are most likely to carry or spread the virus and how illness can change migration timing, stopover behavior, and long-term population viability. This science helps wildlife managers anticipate when and where outbreaks may occur, assess risks to wild birds and domestic poultry, and better protect wetlands, flyways, and communities that depend on healthy waterfowl populations.
