Habitat and Ecology [top]

Habitat and Ecology: It is a nocturnal species, and it probably uses the ground and low understory. This species has been trapped on trees and on the ground, in both primary and secondary forests. It feed predominantly on fruits and insects. It is found in humid lowland Atlantic coastal forests, montane coastal forest to 800 m asl, and semi-deciduous forests of the Cerrado and Caatinga of the Brazilian Plateau, where it lives up to 1,300 m asl (Emmons and Feer 1997, Eisenberg and Redford 1999). During an annual cycle there is a complete turnover in the male population. Since there is one breeding season per year, they conclude that the males exhibit a nearly semelparous breeding strategy (Emmons and Feer 1997, Eisenberg and Redford 1999).
