Clapper Rail
Rail populations declined so significantly that the federal government listed the California Clapper Rail as endangered in 1970.
Most predation of clapper rails takes place during higher tides, when the tidal channels are filled with water and most marsh vegetation is flooded. This happens mostly during the winter season, when very high tides are common. The elevation of the marsh greatly affects which type of vegetation will grow, determining how rails can use the marsh. Low marsh areas with sparse vegetation and tidal sloughs are used by rails for foraging. Higher marsh areas with dense vegetation are used for nesting.
