Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Miller, B., Reid, F., Arroyo-Cabrales, J., Cuarón, A.D. & de Grammont, P.C.
Reviewer(s): Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
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.
Previously published Red List assessments:
1996 Lower Risk/least concern (LR/lc)

Habitat and Ecology [top]

Habitat and Ecology: This bat inhabits in a variety of habitats, including evergreen and deciduous forest, open areas, and villages. It appears to favor slightly disturbed, deciduous forest (Reid, 1997). Roosts in buildings and hollow trees, and colonies may be large. This is one of the first bats to appear at sunset, often flying low to the ground along wide trails on roads. There are two peaks of activity, for an hour after sunset and within an hour of dawn. It feeds on small flying insects, and individuals appear to have established hunting routes. Echolocation calls are short, with maximum energy at 50 to 60 kHz. In Belize, synchronized births occur once a year in the rainy season, and litter size is usually two (LaVal, 1973). Within limits imposed by its elevational distribution, this species is known from almost every major vegetation association in tropical North America (LaVal, 1973). The single specimen reported by Carter and Jones (1978) in the state of Hidalgo, Mexico, was captured over a stream. At Diriamba, Nicaragua, R. tumida was captured over small streams, along a trail in a small ravine, and along trees bordering a hacienda (Jones et al., 1971). Roosting habits of R. tumida are unknown. The only recorded instance of predation on R. tumida is by a male Vampyrum spectrum in northern Guatemala (McCarthy, 1987).
