Although salt marsh habitat loss, However, the number of rails detected in 2019 by all survey including secretive marsh birds, such as the federally endangered California Ridgway’s rail (Rallus obsoletus obsoletus, formerly California clapper rail, hereafter CA Ridgway’s Rail) and state threatened California black rail (Laterallus jamaicensis coturniculus) (U.S. They often roost at high tide during the day. It has a slightly It uses its formidable bill to probe into muddy wetlands for invertebrate prey. Mercury is extremely toxic to bird embryos. The rails are the result of a captive-breeding program. Its numbers now rest in the low thousands, though its slow slide toward extinction continues. The original grouping is now represented on the East Coast of North America by the Clapper rail (Rallus crepitans) and on the West Coast by the Ridgway’s rail (Rallus obsoletus). recent census data indicate that less than 50% of the coastal wetlands in Ridgway’s rails are now restricted almost entirely to the marshes of the San Francisco estuary, where the only known breeding populations occur. Clapper Rail Protocol for the San Francisco Estuary Large Scale Population Surveys January, 2005 General Survey Requirements: 1) Obtain required survey permits: USFWS Endangered Species Permit, ESA Section 10(a)(1)(A); California DFG permits (i.e. It turns out the bird, which rarely flies and sometimes squawks loudly but can be difficult for trained biologists to find, is not related to the Clapper Rails on the East Coast. In south San Francisco Bay, there are populations in all of the larger tidal marshes. They prefer to walk or run rather than fly or swim. It is found principally in California's San Francisco Bay to southern Baja California.A member of the rail family, Rallidae, it is a chicken-sized bird that rarely flies.

Males and females are identical in Working to reduce the effects of contaminants and other stressful impacts on fish wildlife and their habitats and to plan, implement and monitor restoration projects so that fish and wildlife resources can be recovered. The Ridgway’s rail is a grayish-brown, chicken-sized bird with a long, downward curving bill and a conspicuous whitish rump. Many shore birds nest right on the beach. Special Use Permit from a NWR). Encroaching development not only displaces predators from their natural habitat, but also adversely affects higher order predators, such as coyotes, which would normally limit population levels of middle and lower order predators, especially red foxes. It is a rare subspecies of the Savannah sparrow, however it is common on the marshes of San Diego Bay, and the Tijuana Slough National Wildlife Refuge. The United States Fish and Wildlife Service listed it as an endangered species in the 1970s. In July 2014, the North American Check-list Committee upgraded the California Clapper Rail to its own species, and renamed it the Ridgway's Rail. Plant composition influences Ridgway’s rail, and lack of blocks of tidal marsh with suitable structure is the limiting factor for recovery (USFWS 2013). been so extensive that many estuaries where light-footed Ridgway's rails were The Ridgway’s rail is a grayish-brown, chicken-sized bird with a long, downward curving bill and a conspicuous whitish rump.

In addition, an estimated 600 acres of former salt marsh along Coyote Creek, Alviso Slough and Guadalupe Slough, has been converted to fresh- and brackish-water vegetation due to freshwater discharge from South Bay wastewater facilities and is of lower quality for clapper rails. But much of it applies to all birds. It is about migratory song birds. Hydrological Once flushed, they can frequently be approached because they normally fly only a short distance before landing. Their cinnamon breast contrasts with the streaked plumage of the grayish brown back and gray and white barred flanks. Predation impacts are made worse by a reduction in high marsh and natural high tide cover in marshes. population.

Memorandum of Understanding); site-specific permissions (e.g. Access data and maps for the Sacramento Fish and Wildlife Office’s jurisdiction. They can swim well, although swimming is only used to cross sloughs or escape threats at high tide. The results demonstrate that the so-called “rails” are experiencing negative genetic effects following more than a century of salt marsh habitat loss from agriculture, commercial salt production and urban development. The end of the breeding season is typically the end of August, which corresponds with the time when eggs laid during renesting attempts have hatched and young are mobile. Finding a solution for Ridgway’s conditions, and contaminants from urban runoff (USFWS 2009).
