Species Authority: Peters, 1866
Common Name/s:

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor/s: Sampaio, E., Lim, B., Peters, S., Miller, B., Cuarón, A.D. & de Grammont, P.C.
Reviewer/s: Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Justification:
This species is listed as Least Concern in because of its wide distribution, presumed large population, occurrence in a number of protected areas, tolerance to some degree of habitat modification, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Geographic Range [top]

Range Description: This species occurs from southern Veracruz, Mexico, south through the Isthmus to Bolivia, and southeastern Brazil; also Trinidad (Reid, 1997).

Population [top]

Population: Common and widespread (Reid, 1997).
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: The species occurs in evergreen and deciduous lowland forest; it is strongly associated with multistratal tropical wet forest, but also occurs in dry areas; it tolerates second growth woodland, fruit groves, and man-made clearings (Handley, 1976; Eisenberg, 1989; Reid, 1997). It roost in colonies (two to ten; sometimes up to 60) of both sexes. This species makes a wide variety of tents and appears to be an obligate tent rooster. The bat’s prominently striped face may function as disruptive camouflage inside a tent with multiple leaflets (Reid, 1997). They are strongly frugivorous but include insects in their diet (Goodwin and Greenhall, 1961); also flower parts, and nectar may be taken. In Venezuela 0-2,600 m (Lew pers com).
Systems: Terrestrial
