In a world-first for zoos, a nest of abandoned mountain chicken (Leptodactylus fallax) tadpoles has been moved from Durrell Wildlife Conservation Trust to Chester Zoo, and the tadpoles are now being cared for by an adoptive mum. Female mountainchickens normall care for their young, and it is unusual for a female to abandon her offspring. The feamle is now feeding her new brood as if they were her own.
Mount chickens are native to Montserrat and Dominica, but their numbers in the wild have breen drastically decreased due to hunting for food and by chytrid fungus. A number of institutions, including Durrell and Chester, are working collaboratively on a breeding program for the species, as well as undertaking research into the species in the wild.
