Mountain chicken frog
At the Detroit Zoo
The Detroit Zoo is one of only six U.S. zoos that provides a home to the mountain chicken frog. It can be seen at the award-winning National Amphibian Conservation Center – a leader in amphibian conservation and research – which houses a spectacular diversity of frogs, toads, salamanders, newts and caecilians.
The mountain chicken frog is one of the largest frog species, with adults growing up to 8 inches long and weighing up to 2 pounds. This large frog has various types of camouflage; its chestnut-brown color can come in spots or stripes, while its belly is a dark yellow. A black line often runs from its snout to the angle of its mouth. Once abundant in six of the Caribbean islands, the species is now confined to just Dominica and Montserrat.
The call of the mountain chicken frog is a very loud "wooop" which can be heard both day and night.
The mountain chicken frog is a foam nester. During breeding, a foam nest is built by whipping up body secretions; the thick foam nest is where eggs are laid and tadpoles develop. Both parents guard the nest until froglets emerge. The female routinely rebuilds the foam back up as tadpoles develop, and lays infertile eggs for the developing tadpoles to eat.
