What is Avian Influenza (AI)?
USGS is the lead Federal agency for free-ranging wildlife disease research and surveillance. Our capabilities enhance the understanding of wildlife disease ecology and epidemiology as well as inform the development of decision-support and control tools. USGS wildlife disease experts provide technical assistance as needed to manage wildlife disease and conduct cause-of-death investigations.

Advancing Risk Modeling for Highly Pathogenic Avian Influenza
Ongoing global outbreaks demonstrate the capacity of highly pathogenic avian influenza virus (HPAIV) to impact poultry, wild birds, and even human health. USGS research is advancing the understanding of the spatial and temporal interface between wild and domestic bird populations from which these viruses emerge to aid biosecurity planning and outbreak response.
Understanding Circulating Avian Influenza Viruses and How They Spread
USGS research is quantifying the strains and prevalence of avian influenza viruses circulating in wild waterfowl and improving our understanding of how viruses move between and within migratory flyways.
Key Values of a Century of EESC Science
The USGS Eastern Ecological Science Center (EESC) is rooted in a proud tradition of service to the nation—advancing science that informs the conservation and management of fish, wildlife, and habitats across the eastern United States and beyond. Our mission is clear: deliver reliable, partner-driven science that supports natural resource decisions today, while ensuring these resources remain...
Helping Secure Our Nation’s Food Supply: The Intersection of Agriculture, Health, and Environment
Agriculture is vital to the U.S. economy, supplying food, fibers, fuels, and jobs. Ensuring the quality of our natural resources is essential for keeping our food safe and plentiful. The USGS studies environmental factors affecting food security and offers valuable insights to reduce health risks, ensuring a safer food supply and a healthier environment.
EESC Makes an Impact: Protecting Ecosystems to Safeguard Food and Water
Research at the USGS Eastern Ecological Science Center (EESC) supports understanding of the connection between ecosystem health and the quality and availability of America's food and water. USGS studies help monitor and assess the health of terrestrial and aquatic ecosystems, species populations, water quality, and contaminants affecting health and habitats. Information gained through this...
EESC Makes an Impact: Preserving our Hunting Resources
Hunting is an economic engine for the U.S. and responsible management of these resources directly supports 45.2 billion dollars spent by hunters annually. Conservation and management of hunting resources also contributes substantially to the 394.8 billion dollars spent on all wildlife-related recreation. Hunting traditions are an integral component of our American heritage, with 14.4 million...
USGS Wild Bird Avian Influenza Program – Studies from Endemic Regions of Eurasia
This project focuses on tracking wild birds throughout Eurasia via satellite telemetry to better understand their spatiotemporal movement patterns, relationship to domestic birds, and potential role in the spread, persistence, and amplification of avian influenza viruses.
Avian Influenza Research
Since Public Law 109-148, USGS has partnered with state and federal agencies to conduct science to support the national response to highly pathogenic avian influenza (HPAI). In 2014, the first reports of HPAI in US wild birds came from USGS cause-of-death investigations confirmed by the USDA.
Avian Influenza Host Movement Ecology
Understanding disease systems requires an understanding of the basic ecology of host species. USGS is involved in global efforts to explore the movements of bird species that are hosts of avian influenza as well as the potential impacts of changing landscapes on avian influenza.
Using Global Telemetry to Understand Avian Movement and Migration
USGS researchers are collaborating with partners around the globe to leverage new and existing telemetry data to answer broad scale questions about factors influencing avian movement and migration.
Avian Influenza Viral Pathogenicity
USGS is collaborating with numerous partner institutions to explore susceptibility and pathogenesis of relevant avian influenza strains in waterfowl species with special emphasis on sea ducks and diving ducks.
Identifying Spatial and Temporal Trends in Avian Influenza Prevalence in Wild Waterfowl Across the United States
USGS researchers are at the forefront of building and maintaining datasets that represent the spatial and temporal patterns in avian influenza virus prevalence in wild birds, which is critical information used to estimate transmission risk to domestic poultry.
