Common Gallinule is among the Western Hemisphere’s most widespread species, being found even on remote islands such as the Galapagos and Hawaii! Formerly this species was considered to be part of Eurasian Moorhen (Gallinula chloropus), but vocal differences between New World and Old World forms, as well as differences in shield shape and genetics, have led to the New and Old World populations being recognized as separate species. Common Gallinule indeed is common in various marsh habitats, including altiplano wetlands in South America. While it swims when foraging, the gallinule keeps close to the cover of emergent vegetation and hides readily when disturbed. The voice of Common Gallinule is a chattering laugh. In appearance, both Common Gallinule and Eurasian Moorhens are similar in appearance: blackish gray with a pale stripe along the flanks, and a vivid reddish shield and yellow bill.
