Range Description

This species is found along the Pacific coast of Mexico from southern Sonora to northern Chiapas. It is also recorded in the Balsas basin in Michoacán and on the Atlantic coasts of Veracruz.

Habitat and Ecology

This species dwells in tropical deciduous forest and tropical semi deciduous forest in the lowlands. It occurs in disturbed habitats, providing that these are not opened up too much. It breeds in streams.

While the species is known to feed on at least 19 prey taxa, dominant prey items consist of ants, beetles, and termites (Suazo-Ortuño et al., 2007).


This is a very common species.

Population Trend


Major Threats

Local populations might be affected by extreme habitat alteration, but generally this species is not threatened.

Conservation Actions

The preservation of ponds and other water systems is important for the reproduction and preservation of the populations of this species. It is known to occur in at least four protected areas along the Pacific coast (P. Ponce-Campos, pers. comm. 2008).

Red List Status

Least Concern (LC)


Listed as Least Concern in view of its wide distribution, tolerance of a degree of habitat modification, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
