Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-08-09
Assessor(s): Sampaio, E., Lim, B., Peters, S., Miller, B., Cuarón, A.D. & de Grammont, P.C.
Reviewer(s): Solari, S.
Listed as Least Concern because it is widely distributed, it occurs at a number of protected areas, and it is unlikely to be declining at a rate which qualifies it for inclusion in any threat category.

Geographic Range [top]

Range Description:This species ranges from eastern Honduras south through Central America to Amazonian Peru and Brazil (Simmons 2005), also along the Atlantic coast to Espirito Santo, Brazil (Peracchi and Albuquerque 1985), also Trinidad. It prefers lower elevations, below 1,500 m (Reid 2009).

Population [top]

Population:The species is apparently rare (Reid 2009), and with a scattered distribution. Locally common in Costa Rica and Nicaragua (Rodriguez-Herrera, Pineda and Medina pers. comm.).
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:The species is associated with primary forest, but also has been collected in cleared areas around dwellings (Handley 1976). Its activity is concentrated near streams or moist areas (Eisenberg 1989). It roosts in hollow trees, buildings, and under bridges (Williams and Genoways, 2008), it feeds on insects, mainly katydids, cockroaches, June beetles, and Lepidoptera larvae, which are gleaned from vegetation. Wilson (1971) found M. hirsuta to be primarily insectivorous, and suggested its diet fluctuated with the seasons and availability of fruit. This bat is attracted to katydid calls and is much more likely to be caught in mist nets baited nets (where it is seldom captured).

Threats [top]

Major Threat(s): Like other forest-dependent species, this one could be affected by deforestation, although this is not considered as a major threat.

Conservation Actions [top]

Conservation Actions: The species occurs in a number of protected areas throughout its range. However, it is critical to monitor habitat loss at its geographic range.
