Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Lim, B., Miller, B., Reid, F., Arroyo-Cabrales, J., 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 because, although it is widely distributed, and is probably not as rare as indicated by museum specimens due to difficulties in capture (mist nets) and is unlikely to be declining fast enough to qualify for inclusion in the threat categories.

Geographic Range [top]

Range Description: This species is known from a few localities in the Caribbean lowlands of Nicaragua (Koopman, 1993) and Costa Rica (Starrett and Casebeer, 1968; Rodriguez pers. comm.); Colombia (Rodriguez et al., 1995), Guyana (Lim and Engstrom, 2005), Suriname (Lim, unpublished data), French Guiana (Simmons and Voss, 1998), Amazonian Brazil (Fonseca et al. 1996), Panama (Reid pers. comm.). All localities are at or below 500 m elevation.

Population [top]

Population: This is one of the rarest Neotropical bats, know from fewer than twenty individuals taken from less than ten localities in humid lowland areas (Emmons and Feer 1997; Reid 1997).
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: Roosts in groups of 1 to 10 at the top of palm trees on fronds, usually in relatively open areas such as groves or gardens. It hangs freely by the feet when roosting, near the midrib of a frond. Activity starts about 45 min after sunset but is usually restricted to immediately around the roost for 15 to 30 min, after which time, in complete darkeness, individuals disperse, flying at least 3 to 4 m above ground (Starrett 1972; Reid and Langtimm 1993). Adaptable to human disturbed areas. Aerial insectivore.
Systems: Terrestrial

Threats [top]

Major Threat(s): Rarity - but no immediate threats. Not considered rare in Costa Rica (Pineda e Rodriguez pers. comm.).
