Three of the nine wild sea otter populations in the U.S. are federally listed as threatened. In California, USGS biologists have lead an annual population census to assess the local populations' recovery, working closely with state agencies and the Monterey Bay Aquarium.

Photo of a skunk with an ear tag ID. Scientists from the USGS Western Ecological Research Center are studying the movements of skunks and raccoons within Suisun Marsh, CA to understand how they navigate the marsh to reach waterfowl nests. Results will inform the management of waterfowl populations within the Central Valley, CA.

Caspian terns (Hydroprogne caspia) on Island 11 in Pond A16, Don Edwards San Francisco Bay National Wildlife Refuge, California. USGS biologists, at the request of the U.S. Army Corps of Engineers and U.S. Fish and Wildlife Service, used lifelike models of Caspian terns to attract these waterbirds to newly-constructed habitat in the Bay.

The USGS Western Ecological Research Center is monitoring waterfowl populations throughout Suisun Marsh, CA, and the greater Pacific Flyway. Radio transmitters fall off within several weeks and are recovered by scientists for data collection.
