Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Tavares, V. & Soriano, P.
Reviewer(s): Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Listed as Data Deficient in view of continuing problems with its taxonomy as well as absence of recent information on its extent of occurrence, status and ecological requirements.

Geographic Range [top]

Range Description: This species occurs in Colombia, Venezuela (including Margarita Island), north Brazil (only in Roraima -Webster and Handley 1986), Guyana, Trinidad and Tobago, Grenada, St Vincent, Curaçao, Bonaire, and Aruba (Lesser Antilles). The records from Dominica and Ecuador are erroneous (Simmons 2005). 0-2,250 meters (Lew pers. comm.).

Population [top]

Population: The taxonomy is poorly undestood and difficult to extrapolate across current subspecies organizations. Not common in Trinidad and Tobago (Goodwin and Greenhall, 1961)
Population Trend: Unknown

Habitat and Ecology [top]

Habitat and Ecology: This species forms maternal colonies in shelters such as caves and hollow trees. Several hundred females and their young can roost together. Normally a single young is born. The time of reproduction can be strongly seasonal in habitats with pronounced rainfall cycles, but females are polyestrous and can bear two or three young per year. Though fully capable of hovering in flight while taking nectar from flowers, this bat is also to some extent a foliage-gleaning insectivore (Howell, 1983). Activity periods are bimodal, just before dawn and just after dusk. During the period of nectar production by Agave, individual bat will defend the plants against conspecifics to ensure an exclusive supply of nectar and pollen (Lemke, 1984; Willig, 1983). Seems resticted to dry habitat types and open areas (Soriano pers. comm.)
Systems: Terrestrial

Threats [top]

Major Threat(s): As currently defined taxonomically, this species is not threatened. There is some localised destruction of some habitat. It may be composed of several unique species with more restricted ranges.

Conservation Actions [top]

Conservation Actions: Review taxonomic status. Avoid habitat loss.
