Leptodactylus fallax, a large frog inhabiting the Caribbean island of Montserrat, have declined by 80% and is listed as Critically Endangered on the IUCN Red List of Threatened Species™.
Once an abundant species in the wild, it went to the brink of extinction mainly to human consumption (hence its common name of mountain chicken) and because of a deadly fungal infection by Batrachochytrium dendrobatidis.
A sotck of 50 frogs from an uninfected wild population was taken out of the island for ex-situ breeding purposes. 33 healthy offsprings born in captivity were released last January 2012 back into the island, and a field team have been tracking their movements.
