Clapper Rail

Description

14-16" (36-41 cm). A long-billed, chicken-sized rail of salt marshes. All birds have black-and-white barred flanks. Eastern populations are grayish brown without rusty underparts of similar King Rail. Birds on Gulf Coast and in Far West are rustier and more like the King Rail, but do not show rust on shoulders or sides of face. King Rail prefers freshwater marshes.

Habitat

Salt marshes and some freshwater marshes.

Range

Breeds along coasts from central California and Massachusetts southward. Also inland on Salton Sea and lower Colorado River. Winters north to central California and New Jersey, rarely farther north.

Discussion

The rattling call of the Clapper Rail is one of the most familiar sounds in the salt marshes in summer. Generally secretive, the birds are sometimes forced into view by high tides, when they may be seen along roads in the marsh or standing on floating boards. Otherwise they are most often glimpsed as they dart across tidal creeks between sheltering grasses. This species may be confused with the rustier King Rail when the latter enters the salt meadows for the winter.

Nesting

9-12 buff eggs, spotted or blotched with brown, in a shallow saucer or deep bowl of dead marsh grasses, often domed.
