Conservation

The Guam Rail was once abundant on Guam, having evolved on the island without the existence significant predatory species. Following World War II, the brown tree snake was inadvertently introduced to Guam; by the 1960s the effect the snakes were having on native wildlife began to become apparent. The rails were not the only prey species. Nine of the eleven species of native forest birds of Guam (five of them endemic) have been extirpated. The Guam Rail exists in captivity, as does the similarly extinct-in-the-wild Guam Kingfisher. Both species are part of breeding programs, with the hope that they may be reintroduced to the wilds of Guam after the brown tree snake has been eradicated.
