The common gallinule (Gallinula galeata) is a bird in the family Rallidae. It was split from the common moorhen by the American Ornithologists' Union in July 2011. It lives around well-vegetated marshes, ponds, canals, and other wetlands in the Americas. The species is not found in the polar regions or many tropical rainforests. Elsewhere, the common gallinule is likely the most commonly seen rail species in much of North America, except for the American coot in some regions.
The gallinule has dark plumage apart from the white undertail, yellow legs and a red frontal shield. The young are browner and lack the red shield. It has a wide range of gargling calls and will emit loud hisses when threatened.
