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.

Spatial pattern of risk of common raven predation on desert tortoises

Publisher: USGS | Science Center: Western Ecological Research Center (WERC, Sacramento) | Format: .PDF

www.werc.usgs.gov — One cause for declines in desert tortoise populations is predation on juveniles by common ravens (Corvus corax), a predatory bird species native to the Mojave Desert. The Recovery Plan for the Desert Tortoise recommended that research be conducted on sources of mortality (including natural predation). This study was implemented to investigate the More...
