Hawaiian Coot

The ʻAlae keʻokeʻo, also known as the Hawaiian coot in English, is a bird in the rail family, Rallidae, that is endemic to Hawaii. In Hawaiian, ʻalae is a noun and means mud hen. Keʻo is an adjective for clear or white. It is similar to the American coot at 33–40.6 cm (13–16 in) in length and weighing around 700 g. It has black plumage and a prominent white frontal shield. Its natural habitats are freshwater lakes, freshwater marshes, coastal saline lagoons, and water storage areas. The bird was federally listed in October 1970 as an endangered species and is considered both endemic and endangered by the state of Hawaiʻi. It is threatened by habitat loss and introduced predators such as the small Asian mongoose. The Makalawena Marsh on the Big Island of Hawaiʻi has been listed as a National Natural Landmark to preserve one of its last nesting areas.
