Special Use Permit from a NWR). The Ridgway’s rail is a grayish-brown, chicken-sized bird with a long, downward curving bill and a conspicuous whitish rump. The suitability of many marshes for clapper rails is further limited by their small size, fragmentation, lack of tidal channel systems and other habitat features. 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. Southern California’s largest subpopulation of these rails, located in But much of it applies to all birds.
