The Secret Lives of Black Rails, and the Scientists Who Seek Them
Deep in Louisiana marshes, the Black Rail is a master of stealth. Now a tactical team is shining a light on the species, with hopes to demystify its behavior and win it protections.

Coturnicops noveboracensis
Conservation status | Undoubtedly has declined in this century, especially at southern end of breeding range, because of loss of habitat. Localized race in central Mexico is probably endangered if not extinct. |
---|---|
Family | Rails, Gallinules, Coots |
Habitat | Grassy marshes, meadows. In summer, favors large wet meadows or shallow marshes dominated by sedges and grasses. Typically in fresh or brackish marsh with water no more than a foot deep. In winter mostly in coastal salt marsh, especially drier areas with dense stands of spartina; also rice fields, damp meadows near coast. |
Foraging of wild birds essentially unknown. Yellow Rails in captivity feed only by day, picking food from ground, plants, or water.
Usually 8-10. Buffy white, with reddish brown spots around larger end. Incubation is apparently by female only, about 17-18 days. Male may remain near nest during incubation. Young: Apparently fed by female only. Remain in nest only about 2 days, then follow female about in marsh. When not foraging, female and brood go to second nest (not the one in which the eggs hatched). Young find much of their own food after 2 weeks, all of it after 3 weeks; probably able to fly at about 5 weeks.

Mostly insects, snails, seeds. Diet not well known, but small freshwater snails reported to be important at some seasons. Eats a wide variety of insects (especially aquatic ones), also spiders, small crustaceans, probably earthworms. Also eats many seeds, at least in fall and winter.
Male defends territory by calling, mostly at night. In courtship, male and female may preen each other's feathers. Nest site is in shallow part of marsh, on damp soil or over water less than 6" deep. Nest is shallow cup of sedges and grasses, with concealing canopy of dead plants above it. May build more than one nest, with extra(s) being used for brooding the chicks after they leave their hatching nest. Male takes part in starting nests, but female completes the work.
Audubon’s scientists have used 140 million bird observations and sophisticated climate models to project how climate change will affect this bird’s range in the future.
Zoom in to see how this species’s current range will shift, expand, and contract under increased global temperatures.
Choose a temperature scenario below to see which threats will affect this species as warming increases. The same climate change-driven threats that put birds at risk will affect other wildlife and people, too.

As many as 7 million birds in the U.S. die every year when they strike communication towers, but not for much longer.
