Habitat and Ecology [top]

Habitat and Ecology: Nocturnal; probably uses ground and low understory. This species has been trapped arborally and terrestrially, in both primary and secondary forests. It includes fruit and insects in its diet. Found in humid lowland Atlantic coastal forests, montane coastal forest to 800 m, and semi-deciduous forests of the cerrado and caatinga of the Brazilian Plateau. 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 (Eisenberg and Redford, 1999; Emmons and Feer, 1997). To 800 m elevation on coastal mountains and to 1,300 m on the Brazilian Plateau; possibly confined to forests of southeastern Brazil (Eisenberg and Redford, 1999; Emmons and Feer, 1997).
Systems: Terrestrial
