The species was extirpated from the island in the 1980s and was considered to be extinct in the wild for several decades. Following captive breeding programs and other successful conservation efforts, the species was reclassified as Critically Endangered in 2019.

The Guam Rail is a medium-sized rail, recognized by its brownish plumage and thin black and white breast bars. It has a distinctive white eye stripe. Males and females are similar in appearance, although males average larger.

Conservation

The Guam Rail is listed as Critically Endangered on the IUCN Red List and was last assessed in 2012 by BirdLife International. The last individual in the wild of this species died in 1987 following catastrophic declines owing to predation by the introduced brown tree-snake. A captive population survives in a snake-proof enclosure, and it breeds well in captivity. It remains classified as Extinct in the Wild until an introduced population becomes firmly established.
