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)
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

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.)

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.
