This species is present in suitable habitat throughout Amazonian Ecuador, Peru and presumably western Brazil. It ranges up to 1,000 m asl.
Habitat and Ecology
This is an arboreal species occurring in primary and secondary forests (Duellman 1978, Rodríguez and Duellman 1994); this includes seasonally flooded, terra firme and upland tropical forests. It is presumed to breed by direct development; the egg deposition site is not known. It is not recorded from degraded habitats.
It is frequent in good habitat.
There are no major threats; it is a widespread species with large areas of suitable habitat remaining. There is some localized habitat loss due to general human activities such as collection of wood, logging, agriculture (crops, livestock etc.), oil exploration and colonization.
In Ecuador this species is known from many protected areas including Reserva Biológica Limoncocha, and Parque Nacional Yasuní. In Peru the range of this species overlaps with Manu Reserve Biosphere of southern and Pacaya-Samiria Reserve Zone of northern Peru.
Red List Status
Least Concern (LC)
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.
