Sonny Bono Salton Sea Refuge management programs maintain and improve habitat for wintering waterfowl and shorebirds. Waterfowl programs are designed to limit waterfowl depredations to adjacent croplands. The refuge provides habitat for over 375 bird species for many as a critical wintering or migration stopover area.
The refuge winters up to 30,000 snow, Ross's, and Canada geese, and 60,000 ducks from November through February. Marsh birds and shorebirds account for more than 6,000,000 use-days each year. Endangered species observed on the refuge include the southern bald eagle, peregrine falcon, California brown pelican, Yuma clapper rail, and desert pupfish.
A significant Yuma clapper rail population nests on the refuge. Sensitive species using the refuge include the fulvous whistling-duck, wood stork, long-billed curlew, mountain plover, western snowy plover, burrowing owl, and white-faced ibis.
Salton Sea National Wildlife Refuge is located near Brawley, Thermal
