A round elevated platform of grasses, sedges, or rushes, with a saucer-shaped depression, usually with a round or cone-shaped canopy and a ramp. Placed in clump of grass just above water.
|Clutch Size:||6-14 eggs|
|Egg Description:||Pale buff with a few irregular brown spots.|
|Condition at Hatching:||Covered with black down, leave nest within one day. Fed by parents.|
Forages mostly during the day, in areas concealed by plant cover or in comparatively open areas where it blends with its surroundings and is only a few steps from cover. In tidal areas, most feeding is at low tide. Generally forages in water so shallow that only the bill, or part of it, disappears beneath the surface.Back to top
King Rail declined by almost 5% per year between 1966 and 2014, resulting in a cumulative decline of 91%, according to the North American Breeding Bird Survey. The North American Waterbird Conservation Plan does not list a population estimate, but rates the species around a 16 out of 20 on the Continental Concern Score, and lists it as a Species of High Concern. King Rail is on the 2014 State of the Birds Watch List, which lists bird species that are at risk of becoming threatened or endangered without conservation action. The IUCN Red List lists it as a Near Threatened species. Declines in populations are related to the loss of wetlands across North America. Pesticides may also play a role in the bird's decline, and King Rail are often killed by cars when moving around during breeding season.Back to top
