Scientific Name: Eptesicus furinalis (D'Orbigny & Gervais, 1847)

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2015-07-20
Assessor(s): Barquez, R., Perez, S., Miller, B. & Diaz, M.
Reviewer(s): Solari, S.
This species is listed as Least Concern in because of its wide distribution, presumed large population, occurrence in a number of protected areas, tolerance to some degree of habitat modification, and because it is unlikely to be declining at nearly the rate required to qualify for listing in a threatened category.

Population [top]

Population:The species is common and widespread. Apparently, it doesn't show a preference for specific habitats and can use a wide variety of roosts, including man-made structures like roofs, buildings, bridges, tunnels, etc. Usually forming small colonies, of 10-20 individuals.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Biology poorly detailed because of it being found in a variety of habitats, including roosts in trees and houses. Mostly found in moist habitats, but also crossing roads, in orchards, as well as drier habitats like the Brazilian Cerrado, shrub-tree savannah and thorn-scrub associations (Mies et al. 1996). It is an aerial insectivor, stomach contents consist of finely chopped insect remains (Mies et al. 1996).

Threats [top]

Major Threat(s): Because of its large geographic range, and rather independece of specific habitats, the species has no known threats.

Conservation Actions [top]

Conservation Actions: Recent changes in its taxonomic definition (Simmons and Voss 1998) make necessary to promote a comprehensive taxonomic review of its subspecies. Existing data on its ecology and reproduction might include taxa no longer under this specific definition. The species is found in several protected areas through its geographic range.
