Assessment Information [top]

Red List Category & Criteria:

Near Threatened ver 3.1

Year Published:

2008

Assessor/s:

Miller, B. & Medina, A.

Reviewer/s:

Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)

Justification:
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.

History:

1996

Vulnerable

Geographic Range [top]

Range Description:	This species occurs in Jalisco, Veracruz, Oaxaca, and Chiapas (Mexico); Guatemala; Belize; Honduras (Simmons 2005). It occurs from lowlands to 2,300 m (usually below 1,300 m). Northern of Nicaragua in Jinotega (Medina et al. in press).

Population [top]

Population:	This bat is apparently uncommon and local (Reid, 1997).
Population Trend:	Unknown

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).
Systems:	Terrestrial
