Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-07-01
Assessor(s): Lim, B., Miller, B., Reid, F., Arroyo-Cabrales, J., Cuarón, A.D. & de Grammont, P.C.
Reviewer(s): Solari, S.
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), Costa Rica (Starrett and Casebeer 1968, Reid 2009), Panama (Reid 2009), Colombia (Rodriguez et al. 1995), Guyana (Lim and Engstrom 2005), Suriname (Lim 2009), French Guiana (Simmons and Voss 1998), Amazonian Brazil (Fonseca et al. 1996), Peru (Velazco et al. 2011) and Bolivia (Aguirre et al. 2010). All localities are at or below 500 m elevation (Tavares et al. 2012).

Population [top]

Population:This is one of the rarest Neotropical bats, known from fewer than 30 individuals taken from less than 20 localities in humid lowland areas (Reid 2009, Velazco et al. 2011, Tavares et al. 2012).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

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.
