From the IUCN Red List Species Account:


Range Description

This species is found on the Lower Amazonian slopes of the Andes in Ecuador and Colombia. Specimens previously referred to from central Peru (Departments of Junin, San Martin and Ucayali) have now been included in O. elkejungingerae (Karl-Heinz Jungfer pers comm.). It is possible that specimens considered to be O. verricigar in Colombia might refer to a different species (Karl-Heinz Jungfer pers comm.). It has an altitudinal limit of 1,400-2,000m asl.

Habitat and Ecology

This species’ habitat is montane and lowland tropical rainforests. At Cordillera del Dúe, Ecuador, the vegetation consists of lower humid montane forest, where there are many large trees, but the canopy is incomplete. Mosses and small ferns are abundant, and a thick layer of leaf-litter is present. Individuals of this species have been found in a broad, shallow ravine near to a stream. Males have been observed calling from low bushes and rocks along a pool in the stream (Trueb and Duellman, 1970). Breeding takes place in pools and slow streams. The species can be found alongside roads and in very disturbed habitat.


This is a common species.

Population Trend


Major Threats

There is some localized habitat loss to general human activities such as agriculture (crops, livestock etc.) and logging, but since the species is very adaptable, these are probably not having a very serious impact on the species.

Conservation Actions

In Ecuador, its geographic range overlaps with Reserva Ecológica Cayambe-Coca, and Parque Nacional Sumaco Napo-Galeras. In Colombia it might occur in Cuevadea los Guacharos.

Taxonomic Notes

There are serious taxonomic problems with this species (K.-H. Jungfer pers comm.).
