Birds
(Waterfowl, Shorebirds, Fowl, Raptors, and Passerines) - Migratory birds have been a major focus of the research program at various USGS science centers across the country. Studies have emphasized population biology and habitat needs of waterfowl and other grassland and wetland birds. Past and current research contributes to monitoring habitat and wildlife conservation of avian populations and improved management of their habitats.

Satellite Tracking Migratory Birds
Migration is the regular seasonal movement of animals from one place to another, often from breeding to non-breeding sites, and is common among most birds. USGS has developed partnerships in North America with several groups including Ducks Unlimited, California Waterfowl Association, and the Sea Duck Joint Venture, as well as several international partnerships, to study movements of migratory birds, especially in relation to risks of disease transmission. Follow the links on the menu bar for details on projects and to see migration maps for different species.
