Sonny Bono Salton Sea National Wildlife Refuge
One of the best areas for bird watching in Southern California is the Salton Sea National Wildlife Refuge (NWR). The Refuge was established in 1930 by Presidential Proclamation. Originally, the refuge consisted of approximately 35,000 acres. Now, because of flooding by the Salton Sea, only about 2,200 manageable acres remain. Dikes are expected to keep the sea from further expansion on the refuge.
The Salton Sea is located in the Sonoran Desert of Imperial and Riverside counties just north of El Centro, California. The habitat contains 35,484 acres of salt marsh and open water, 2,000 acres of pasture and freshwater marsh. The sea is 35 miles long and is one of the lowest places in the United States, about 228 feet below sea level.
Looking for the birds
The Salton Sea has one of the most diverse bird species of any NWR in the west. More than 375 birds have been recorded in the Salton Sea and Imperial Valley regions. Heavy migrations of waterfowl, marsh and shorebirds appear during the spring and fall. During the winter and spring, a variety of smaller birds and raptors occupy the refuge. The best months for bird watching at the Salton Sea are November to May.
The primary purpose of the refuge is to provide habitat for migrating and wintering waterfowl and endangered species. The refuge is also important in providing feeding, resting and nesting habitat for a large number of shorebirds, and in supporting a diversity of wildlife species throughout the year.
Other animals introduced into the Salton Sea, accidentally or intentionally, include barnacles, pile worms and copepods. These animals play an important role in providing food for the fishery. The relationship between the fish and their food is so close that, if one were to disappear, the entire system would be significantly affected.
Thousands of waterfowl and other birds spend the winter here. Canada Geese, Snow Geese, American Avocets, Black-Necked Stilts, Pintails, Green-winged Teal, Eared Grebes and a wide variety of other species are commonly seen during the winter.
Endangered species at the refuge include the Yuma Clapper Rail, which occurs in suitable habitat throughout the year and breeds in marshes around the southeastern portion of the Salton Sea. Other endangered or threatened species occasionally observed on the refuge include the Bald Eagle, California Brown Pelican and Peregrine Falcon.
Before the Salton Sea was formed, waterfowl were only found along the marshes and delta of the Colorado River (primarily in Mexico). During the 1920s, as more water was diverted from the Colorado River for agriculture, marshes were inadvertently created. These marshes, at the edges of the then-smaller Salton Sea, resulted from agricultural water runoff. Waterfowl were attracted to the marshes from their former winter home in the drying Colorado River Delta.
As farming intensified in the 1940s and the Salton Sea expanded, marshland once again shrunk and waterfowl turned to farmers' crops for food. Today, crops are grown on the refuge to feed wintering waterfowl and to keep the birds from eating agricultural crops.
The Refuge headquarters has a visitor center and kiosks where information on and a bird exhibit provides the opportunity to see many of the bird species common the Salton Sea. A free wildlife list which contains birds, mammals, reptiles, amphibians and fish is also available.
