English Brazilian Brown Bat

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.

Geographic Range [top]

Range Description:E. brasiliensis occurs from Nayarit and Veracruz to the south of South America. In Mexico, it occupies middle elevations of the Sierra Madre Occidental, Sierra Madre Oriental, and Chiapas (Ceballos 2014). It does not occurs in western Mexico (Arroyo-Cabralles pers. comm.). In South America is found on Trinidad and Tobago, and in Colombia, Venezuela, Guyana, and Surinam south through Ecuador, Peru, Brazil, and Paraguay into Uruguay and northern Argentina (Simmons 2005, Gardner 2008). Subgenus Eptesicus; does not include andinuschiriquinusinca, or montosus; see Davis (1966) and Simmons and Voss (1998). At least four subspecies are currently recognized (Simmons 2005). May be a species complex (R. Barquez pers. comm.).
Countries occurrence:
Argentina; Brazil; Colombia; Costa Rica; Ecuador; Guatemala; Mexico; Panama; Paraguay; Peru; Trinidad and Tobago

Population [top]

Population:Fairly locally common throughout most of its geographic range, but it may be uncommon on some marginal localities at the north (Mexico) or south (Argentina). Similar to other tropical insectivores, large colonies are not known.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The species is usually found in moist habitats, including montane and lowland forests, gallery forests, open areas, orchards and plantations. It is an aerial insectivore species, that roosts in houses and hollow trees (Emmons and Feer 1997). Active comparatively earlier than other bats; individuals might be seen foraging around lights, and patrolling a circular path (Reid 2009).

Threats [top]

Major Threat(s): Because this species has no specific habitat requirements, no threats can be identified throughout its extense geographic range.

Conservation Actions [top]

Conservation Actions: Same as other Neotropical insectivores with large geographic distributions, this species needs a thoroughly taxonomic review. Through its range, it is found at several protected areas. Large variation is expected among geographic populations and even subspecies, this may include ecological or reproductive aspects that need to be taken in account for specific conservation actions.
