This species is listed as Data Deficient in view of a lack of information on biology, ecology and population status of this species, there are also continuing uncertainties about its distribution.

Population [top]

Population:This species is poorly known and considered by Emmons and Feer (1997) to be rare everywhere in its geographic range. However, this species may be confused with P. macrotis and so may be less rare than previously thought. It can be common, for example in caves in Venezuela (Hood and Gardner 2008); Brosset and Charles-Dominique (1991) mentioned finding a roost in the vicinity of Cayenne, French Guiana, containing over 100 individuals. As an aerial insectivore, it may be underrepresented in mistnet sampling, but can be more easily captured at roost sites.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Very little is known on the natural history of this species. Roosts are in hollow trees and in hollow rotten logs on the ground (Eisenberg 1989) or under overhanging banks (Emmons and Feer 1997). Handley (1976) reported P. trinitatis roosting in rocks, caverns, and houses in Venezuela. Most (75%) were taken in dry areas; others were taken in savannah, pasture, yards, swamp, and evergreen forest; all at elevations under 400 m. Also found in caves in the Llanos in Venezuela (Lim pers. comm.). This is an aerial insectivore of background cluttered space. Distributional limits are still poorly known (Lim pers. comm.).

Threats [top]

Major Threat(s): Threats for this species are unknown.

Conservation Actions [top]

Conservation Actions: Surveys are needed to confirm the distribution of the species. Need to review museum specimens of P. macrotis to confirm whether or not actually correspond to this species.
