From the IUCN Red List Species Account:


Range Description

This species is known only from three localities in the Upper Río Pastaza Valley in the vicinity of Yungilla and Mount Tungurahua, near Baños, in Tungurahua Province, Ecuador. Its altitudinal range is 1,800-1,840m asl. Additional survey work may reveal that the species occurs more widely than current records suggest.

Habitat and Ecology

It is known only from altered, degraded montane forest, with some exotic trees. Its apparent rarity might be related to it possibly having a strong preference for pristine habitats, where it could prove to be more common. Breeding is believed to by direct development, but the site of egg deposition is not known.


It has always been a rare species.

Population Trend


Major Threats

The major threat is habitat loss and degradation due to agricultural development, rearing of livestock, logging, and human settlement.

Conservation Actions

It is not known from any protected areas, though it is possible it may occur in Parque Nacional Sangay. Further survey work is required to better understand the range and ecology of this species.
