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.
Reviewer(s): Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
This species is listed as Least Concern in view of its wide distribution, presumed large population, 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 has been found in Colombia, northern Bolivia, southern Venezuela, Guyana, Suriname French Guyana, and the Amazon basin of Brazil (Engstrom and Lim, 2000; InfoNatura, 2004; Lim and Engstrom, 2000; Marinkelle, 1968).

Population [top]

Population:The species is rarely encountered because it is difficult to capture due to its high flying and roosting behaviors (Emmons and Feer, 1997).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:This bat occurs in evergreen forest in the Amazon Basin. It feeds on large insects (Barquez et al., 1993), for which the audible echolocation is an adaptation (Emmons and Feer, 1997) and roosts in small groups in tree holes, cliffs, roofs and attics of buildings (Emmons and Feer, 1997). Females form maternity colonies during the breeding season; a single young is born each year (Eisenberg, 1989).

Threats [top]

Major Threat(s): There are no major threats throughout its range.

Conservation Actions [top]

Conservation Actions: Reduce loss of forest habitat.
