The Yellow Rail, Coturnicops noveboracensis is a small waterbird, of the family Rallidae.
Adults have brown upperparts streaked with black, a yellowish-brown breast, a light belly and barred flanks. The short thick dark bill turns yellow in males during the breeding season. The feathers on the back are edged with white. There is a yellow brown band over the eye and the legs are greenish-yellow.
Their breeding habitat is wet meadows and shallow marshes across Canada east of the Rockies; also the northeastern United States and the entire northern US-Canadian border Great Plains to the Great Lakes. A small population may exist in northern Mexico. The nest is a shallow cup built with marsh vegetation on damp ground under a canopy of dead plants.
The Yellow Rail are very elusive and seldom seen; when approached, they are more likely to rely on camouflage than flight. The bird's call, usually given at night, sounds like two stones being clicked together. Their numbers have declined in recent years due to loss of habitat.
