The mountain chicken is a Critically Endangered frog found only on Montserrat and Dominica and is the largest native amphibian in the Carribean. Populations on both islands have been devastated by the amphibian chytrid fungus, first on Dominica from 2002 and subsequently from 2009 on Montserrat. The wild population across both islands is currently estimated to be about 100 individuals.
