Guam Rail

Hypotaenidia owstoni Rothschild, LW 1895

The Guam rail is a species of flightless bird, endemic to the United States territory of Guam, where it is known locally as the Ko'ko' bird. 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. Since 1995, more than 100 rails have been introduced on the island of Rota in the Commonwealth of the Northern Mariana Islands in an attempt to establish a wild breeding colony. Although at least one chick resulted from these efforts, feral cat predation and accidental deaths have been extremely high. In 2010, 16 birds were released onto Cocos Island, with 12 more being introduced in 2012. In 2019, the species became only the second bird after the California condor to be reclassified by the IUCN from extinct in the wild to critically endangered. Source: Wikipedia
