Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:In Venezuela, it is strongly associated with moist habitats and multistratal evergreen forest (Handley 1976), but can occupy a variety of disturbed and undisturbed forest habitats (Davies and Dixon 1976). These bats probably roost in trees and shrubs. This species is largely frugivorous, preferring figs. Although poorly documented, the diet is primarily fruits (Gardner 1977). Reproduction is seasonally timed by the onset of rain (Wilson 1979).

Threats [top]

Major Threat(s): Deforestation, although this is not a major threat.

Conservation Actions [top]

Conservation Actions: Reduction of habitat loss is needed.
