The yellow rail (Coturnicops noveboracensis) is a small secretive marsh bird, of the family Rallidae.
Contents
Description
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.
Measurements:
- Length: 5.1-7.1 in (13-18 cm)
- Weight: 1.4-2.4 oz (41-68 g)
- Wingspan: 11.0-12.6 in (28-32 cm)
Distribution
Their breeding habitat is wet meadows, fens and shallow marshes across Canada east of the Rockies; also the northeastern United States and the entire northern Canada–US border Great Plains to the Great Lakes. A small population may exist in northern Mexico.
The yellow rail migrates to the southeastern coastal United States.
Behaviour
The yellow rail are very elusive and seldom seen. They generally call at night resembling the sound of two stones being clicked together "tik-tik tik-tik-tik" in repetition. When approached, they are more likely to rely on camouflage and escaping on foot through dense vegetation, rather than flushing.
Breeding
The nest is a shallow cup built with marsh vegetation on damp ground under a canopy of dead plants. It is made out of woven grasses and leaves.
This rail lays a clutch of five to 10 oval or elongate eggs that usually measure around 29 by 21 millimetres (1.14 by 0.83 in). These eggs are creamy, and spotted with both reddish spots that form a ring at one end, and small black spots that are scattered over the egg. They are incubated by the female for a period of 16 to 18 days. If the first set of eggs are destroyed, the female will generally lay another clutch. After the chicks hatch, the female will either crush the eggshells and hide them from view at the bottom of the nest, or remove the eggshells from the nest, dropping them along the paths leading away from the nest.
Diet
The yellow rail feeds primarily on small invertebrates and complements its diet with plant seeds. Beetles (Coleoptera) account for the highest proportion of the birds' diet, followed by spiders (Araneae) and snails (Gastropods), whereas plant matter is dominated by sedges (Cyperaceae) and rushes (Juncaceae).
Status
Their numbers have declined in recent years due to loss of habitat.
