The Whistling Frog, Leptodactylus fuscus (Family Leptodactylidae)

As currently defined it occurs from the Pacific lowlands of Panama throughout South America, east of the Andes to northern Argentina. It is found over most of Trinidad and Tobago (absent from Little Tobago Island) and is perhaps the most common and abundant frog in the islands. It is terrestrial and nocturnal, using open habitats (savannahs, grasslands, marshy areas, degraded forests and urban habitats). Males calling at the onset of rains. Breeding takes place in small burrows in shallow temporary wetlands and the edges of permanent bodies of water. The eggs are deposited in foam nests within a burrow. When the burrows flood the larvae escape into the adjacent wetlands where the tadpoles then develop.
