2003). Birds at the sea are concentrated on Mullet Island and along the shoreline near the Whitewater River delta and between the mouths of the Alamo and New Rivers. The Salton Sea and the Imperial and Mexicali Valleys are important areas for breeding herons and ibises. Tens of thousands nest in rookeries dotting the northern and southern shorelines, and just as many breed in the massive rookery at Finney and Ramer Lakes just south of Calipatria. Breeding species include the Least Bittern, the Great Blue and Green Herons, the Great, Snowy, and Cattle Egrets, the Black-crowned Night-Heron, and the White-faced Ibis.

Mudflats and shallows in large freshwater and brackish impoundments, like these evaporation ponds along Morton Bay south of Wister, provide an abundance of habitat for migrant and wintering plovers, sandpipers, and other shorebirds. Mullet Island is visible in the background. Photograph by Jack W. Schlotte and Philip Unitt. FIGURE 19. Relative abundance of seabirds breeding at the Salton Sea in the late 1990s.

Not surprisingly, the Brant, the scoters, the Long-tailed Duck, and the Red-breasted Merganser are closely associated with the Gulf of California. Movement through the Salton Sink by each of these is by far most conspicuous in spring (mid-March to mid-May), when birds wintering in the gulf move northward through the region. Based on the thousands of scoters detected on inland lakes in San Diego County (Unitt 1984) and the numerous records of migrant flocks of Brant over the Anza-Borrego Desert, it would appear that most traverse a path to the west of the Salton Sink (Fig.
