Assessor(s): Miller, B., Reid, F., Arroyo-Cabrales, J., Cuarón, A.D. & de Grammont, P.C.
Reviewer(s): Solari, S.
Listed as Least Concern because it is widely distributed and unlikely to be declining at a rate which would qualify the species for inclusion in the threat categories.

Population [top]

Population:The species is widely distributed. It seems to be relatively uncommon but populations are poorly understood and it may be under represented in studies due to sampling bias. There are just two records in Costa Rica (LaVal and Rodriguez-H. 2002). It is apparently rare in Central America (Reid 2009).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This species is poorly known. This frugivore inhabits a variety of dry and humid tropical and subtropical forests at elevations up to 1,000 m, but is more commonly found below 500 m (Gardner 2008). In Venezuela it prefers moist habitats and multistratal evergreen tropical forest (Handley 1976). The type specimen from Trinidad was caught in a well-lit cave (Goodwin and Greenhal 1961). Found in evergreen forest and forest openings; it probably travels in the canopy or subcanopy, as it is seldom caught in nets set at understory level (Reid 2009).

Threats [top]

Major Threat(s): Habitat loss in some parts of the range, although this is not a major threat.

Conservation Actions [top]

Conservation Actions: Reduce loss of forest habitat is needed. It is found in protected areas.
