COSEWIC assessment and status report on the yellow rail, Coturnicops noveboracensis, in Canada. : CW69-14/408-2024E-PDF
"This small, secretive marsh bird breeds in shallow, grassy marshes and wet meadows from eastern British Columbia and the Northwest Territories to New Brunswick, and the northern United States. About 90% of its breeding range is in Canada, and it winters in shallow coastal marshes and rice fields from Texas to North Carolina. Increased search effort has raised the population estimate to 18,000 to 65,000 mature individuals, 3-4 times the previous estimate. Population trends are poorly monitored, and although there is no evidence of an overall reduction in the Canadian population, there are indications of local declines. It is threatened by ongoing wetland loss and degradation in parts of its breeding and wintering grounds, often due to agriculture and industrial activity. Climate change may further alter hydrological regimes and cause drier conditions in some areas. This population may become Threatened if ongoing deterioration of wetland habitat is not reversed or managed effectively"--Reason for designation, page iii.
