Range Description This species is known from the Pacific coast of western Colombia in the Choco region, from close to the Ecuador border, north to the lower Magdalena River basin in Colombia, east to the Maracaibo Lake basin in Venezuela, and from Barinas and Táchira States in Venezuela. It occurs below 1,040m asl.
Habitat and Ecology It is found in seasonal and moist tropical lowland forests, and has not so far been found outside forest. It is not known whether or not it can survive in degraded, open areas. Its breeding system is unknown.
Population No information is available on its abundance.
Population Trend unknown
Major Threats Deforestation as a result of expanding agriculture is a potential threat, but there is not enough information to confirm this.
Conservation Actions It probably occurs in some protected areas in Colombia and Venezuela.
Red List Status Least Concern (LC)
Rationale Listed as Least Concern in view of its wide distribution, presumed large population, and because it is unlikely to be declining fast enough to qualify for listing in a more threatened category.
Taxonomic Notes This is a poorly circumscribed species in need of taxonomic review (M. Wilkinson pers. comm.).
