This subspecies can be distinguished from the others by the large rufus patch on the upper back. Junín rail, L. j.tuerosi Fjeldså, 1983 – only found in the marshes of Lake Junín, Peru. The Junín Rail is considered Endangered because of its limited range. The Junín rail can be distinguished from other subspecies by its plain undertail coverts and pale legs. Description The black rail is a small black bird with a short bill. Black rails usually weigh 29-39 g, are 10-15 cm in length, and have a wingspan of 8.7-11.0 in (22-28 cm).The body is dark, with white speckles along the back and wings. Both the beak and legs are dark. Adults have a red eye that appears around 3 months of age. It will often make its presence known with its distinctive ki-ki-krr call or an aggressive, presumably territorial, growl. This is primarily uttered during the night, when these birds are most vocal. The peak of vocalization is during the first two weeks of May, when breeding and courtship behaviors are also at their peak. Distribution and habitat It is found in scattered parts of North America, the Caribbean, and the Pacific region of South America, usually in coastal salt marshes but also in some freshwater marshes. It is extinct or threatened in many locations due to habitat loss. The largest populations in North America are in Florida and California. Behaviour and ecology The black rail is rarely seen and prefers running in the cover of the dense marsh vegetation to flying. Breeding This rail is territorial during the breeding season, and occasionally males will mate with two or more females. The nests of this bird are placed on the ground, in dense, swampy vegetation or in patches of flooded grass. The nests are bowl-shaped and built with vegetation loosely woven. The clutch of this bird usually consists of six to eight creamy white speckled, with reddish-brown spots, eggs. These eggs are roundish and measure around . They are incubated by both parents, taking shifts of approximately one hour each, for 16 to 20 days. The young then hatch. In 2015, the first ever breeding by black rails in South Carolina was captured through a camera study. This species was once thought to be a non-breeding visitor to the state. Food and feeding The black rail is an opportunistic feeder and consumes a wide range of food. Its
