Habitat and Ecology
This is a terrestrial and nocturnal frog found in open country, savannahs, grasslands, marshy areas, degraded forests and urban habitats. Males of this species start calling at the onset of the very first rains. Breeding takes place in small burrows in shallow temporary wetlands and the edges of permanent lagoons. The eggs of the species are laid in foam nests within the burrows, when the burrows flood the larvae escape into the adjacent wetlands where the tadpoles then develop. It is an adaptable species that can survive in modified habitats.
It is common throughout much of its range, although it is generally not a common species in Panama.
There are no major threats to this species.
It occurs in many protected areas in South America, but none in Panama.
This form is probably a complex of more than one species.
