Habitat and Ecology:This nocturnal and arboreal species is strongly associated with multistratal tropical evergreen forest (Eisenberg and Redford 1999). Habitat generally includes bamboo and cane thickets on the margins of seasonally inundated and upland rainforest. In Ecuador specifically, this species can be found in the canopy of tall forests. (Emmons et al. 2015). It is social and forages in bamboo clumps in family groups (Eisenberg and Redford 1999). Its home ranges reach up to 0.43 ha (Eisenberg and Redford 1999). It is a varzea specialist and is rarely seen but can be heard because of its very distinctive call. Little is known on the reproductive biology of this species, but pregnant females have been reported at the end of the rainy season in June in the central Amazon (Emmons et al. 2015).
