From the IUCN Red List Species Account:
This species can be found throughout much of Amazonian Ecuador, and a single site in northeastern Peru. It might range further south, as it is often confused with a similar Osteocephalus. Its elevational range is 200-1,200m asl.
Habitat and Ecology
Specimens have been found in primary forest and forest edge (Duellman, 1978; Jungfer and Hödl, 2002). This is an arboreal species that breeds in temporary ponds and slow moving streams. It may occur in slightly degraded habitats.
It is not uncommon.
Although there is considerable loss of habitat in Ecuador through settlement and agriculture, there are still large areas of suitable habitat available to this species.
In Ecuador, its geographic range overlaps with several protected areas including Parque Nacional Sumaco Napo-Galeras, and Reserva Biológica Limoncocha.
Osteocephalus mutabor was previously confused with O. leprieurii, from the Amazon Basin of Ecuador (Jungfer and Hödl 2002)
