Scientific Name: Micronycteris schmidtorum Sanborn, 1935
Common Name(s):
English Schmidts's Big-eared Bat

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-07-05
Assessor(s): Sampaio, E., Lim, B. & Peters, S.
Reviewer(s): Solari, S.
Listed as Least Concern because it is widely distributed, however, it is represented by low numbers locally. It is unlikely to be declining at a rate which would qualify the species for inclusion in a threatened category.

Population [top]

Population:It is apparently rare and with a scattered distribution.
Current Population Trend:Stable
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:It is poorly known. It is found in evergreen and deciduous lowland forest and forest edge. Handley (1976) reported M. schmidtorum roosting in tree holes and recorded captures of this species from a variety of habitats including evergreen forest, thorn forest, swamps, pastures, and orchards. In French Guiana, it was netted in ground-level mistnets in well-drained primary forest (Simmons and Voss 1998). Small groups roost in hollow trees. Moths are included in the diet (Howell and Burch 1974).

Threats [top]

Major Threat(s): Deforestation, although this is not a major threat.

Conservation Actions [top]

Conservation Actions: Forest retention is needed. In Mexico is listed as threatened under NOM - 059 - SEMARNAT - 2001 (Arroyo-Cabrales pers. comm.).
