Assessment Information [top]

Red List Category & Criteria: Near Threatened ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Miller, B. & Medina, A.
Reviewer(s): Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Listed as Near Threatened because, although the species is still reasonably widely distributed, it is dependent upon a highly fragile habitat and is in significant decline (but at a rate of less than 30% over ten years) due to human population density in the island and habitat conversion. Almost qualifies as threatened under criterion A.

Habitat and Ecology [top]

Habitat and Ecology:This species can be found in a variety of forested habitats from lowland deciduous to montane pine-oak and cloud forest (Reid, 1997; Engstron et al., 1987). Little is known of the roosting habitats of this species, except for one individual that was caught in a building. It is active within an hour of sunset and lies low to the ground along forest trails. Its anatomy suggests that this bat may feed by gleaning insects from the ground or vegetation. In captivity, it readily consumes large insect such as cockroaches and katydids (Engstrom et al. 1987; Reid, 1997). In Mexico it has been reported in deciduous forest (Coates-Estrada and Coates, 1986).

Threats [top]

Major Threat(s): Habitat loss, restricted to intact forests. In Mexico it does not have important habitat loss (Cuaron and de Grammont pers. comm.).

Conservation Actions [top]

Conservation Actions: Found in private protected areas in Belize. Found in protected areas in Mexico.
