Waterbird Ecology and Movement in the Terminal Lakes Across the Great Basin
How do changing conditions in the terminal lakes of the Great Basin effect the migratory birds that depend on them? USGS scientists investigate bird movement and habitat use to find out.
AIMS for Wildlife
We are building a 21st century wildlife monitoring system to inform resource management of the impacts of drought, wildfire, land use, climate change, and other landscape level stressors. The Automated Interactive Monitoring System (AIMS) for Wildlife will provide an actionable data stream by combining enormous quantities of wildlife movement data with environmental data and delivering it to...
Goose Population Dynamics in the California Central Valley and Pacific Flyway
USGS scientists and partners are studying how growing goose populations in the California Central Valley wintering areas are affecting ducks and other waterfowl.
Suisun Marsh Waterfowl and Wildlife Studies
Suisun Marsh provides critical habitat for wintering and breeding waterbirds in California. USGS WERC collaborates with the California Department of Water Resources to examine trends in bird declines and to assess the habitat factors driving long-term survival of waterfowl, rails, and other birds in this important area.
Integrating Remote-Sensing and Ecological Forecasting into Decision-Support for Wetland Wildlife Management in the Central Valley of California
In the Central Valley of California, the few remaining wetlands plus cropland that is flooded after harvest provide critical habitat for wetland-dependent species. However future climate conditions and a growing human population will challenge how they are managed. To support coordinated conservation, wetland restoration, and climate adaptation planning, we partnered with Point Blue Conservation...
Waterfowl Ecology in California and the Pacific Flyway
The Suisun Marsh and Central Valley in California offer some of the world’s most important wetland habitats for waterfowl in the Pacific Flyway. Mike Casazza and USGS WERC biologists are providing the science to support and evaluate waterfowl populations and habitat management in North America.
Dixon Field Station
WERC scientists at the Dixon Field Station conduct studies from the San Francisco Bay-Delta in California to the Great Basin spanning California and Nevada.

Tule Goose Migration Tracks, 2019 and 2020
Fall migration routes for tule geese in 2019 (five geese) and 2020 (four geese) through arrival at Summer Lake Wildlife Area, Oregon. This area experienced massive wildfires in 2020 which resulted in aberrant migration behavior, increased energetic demands, and increased mortality risk.
