ANIMALIA CHORDATA MAMMALIA CHIROPTERA PHYLLOSTOMIDAE

Scientific Name: Uroderma magnirostrum

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor/s: Sampaio, E., Lim, B., Peters, S. & Arroyo-Cabrales, J.
Reviewer/s: Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
Justification:
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.

Geographic Range [top]

Range Description: This species ranges from Michoacan, Mexico, south through the Isthmus to central Brazil. It generally occurs below 1,000 m elevation; most specimens being taken at below 800 m (Eisenberg, 1989; Reid, 1997). It is found in southern Venezuela and Guyana, but there are no records from French Guiana or Suriname (Lim and Patterson pers. comm.). No records for Costa Rica (Bernal Rodrigues and Pineda pers. comm.)

Population [top]

Population: It is not as common as U. bilobatum, but is not uncommon.
Population Trend: Stable

Habitat and Ecology [top]

Habitat and Ecology: It is often associated with moist habitats, as deciduous and evergreen forest and near water in arid regions (Davis, 1968). In Venezuela, it makes use of open areas and man-made clearings and seems less tolerant of arid habitats than U. bilobatum (Handley, 1976). This bat roosts under palm fronds or banana leaves or other large leaves of palms (i.e. Astrocaryum sp.). They often bite through the ribs of fronds and cause the leaf to collapse on itself, thereby providing a shelter (Eisenberg, 1989). One tent was occupied by 5 bats (Timm, 1987). Females roost in colonies when they bear their young, and the sexes tend to roost separately during the rearing season. In Panama young are born from February through April (Wilson, 1979). They are strongly frugivorous but include insects in their diet (Goodwin and Greenhall, 1961); several individuals caught were dusted with pollen, presumably after feeding on nectar or flower parts (Gardner, 1977).
Systems: Terrestrial
