Wikipedia Abstract

The Guam rail (Gallirallus owstoni) (Chamorro name: ko'ko' ) is a flightless bird, endemic to the United States territory of Guam. The Guam rail disappeared from southern Guam in the early 1970s and was extirpated from the entire island by the late 1980s. This species is now being bred in captivity by the Division of Aquatic and Wildlife Resources on Guam and at some mainland U.S. zoos.
