Kingdom Phylum Class Order Family
Animalia Chordata Mammalia Chiroptera Natalidae

Scientific Name: Natalus stramineus Gray, 1838
Common Name(s):
English Mexican Funnel-eared Bat
Taxonomic Notes: Does not include N. espiritosantensis, N. jamaicensis, N. major and N. primus - those are all treated as distinct species. Arroyo-Cabrales et al. (1997) reviewed genetic variation and possible relationships of populations of major and stramineus (Simmons 2005).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2016-07-09
Assessor(s): Davalos, L. & Tejedor, A.
Reviewer(s): Solari, S.
Listed as Least Concern in view of its abundance within its restricted distribution, its presumed large population, and because its habitat is unlikely to be declining fast enough to qualify for listing in a more threatened category.

Geographic Range [top]

Range Description:The species is known from Islands of Lesser Antilles north of St Lucia Chanel: Anguilla, Antigua, Barbuda, Dominica, Guadeloupe, Marie Galante, Martinique, Montserrat, Nevis, Saba, and Sait Maarten (skeletal remains only) (Tejedor 2006, 2011).

Population [top]

Population:The species seems locally common in at least four islands (Antigua, Barbuda, Dominica and Saba; Genoways et al. 2001; S.C. Pedersen, pers. comm.)
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Natalus stramineus occurs from sea level to middle elevations and in habitats ranging from relatively dry (e.g., Barbuda, 925 mm annual precipitation) to rain forest (e.g., Sylvania, Dominica, 3232 mm) (Tejedor 2011). Often capured in xerophitic habitats among dry forest scrub (Pedersen 2005). Only found in dark humid caves, usually in the most remote portions of the cave system. Although its diet has never been studied, N. stramineus is surely insectivorous, as are other representatives of Natalidae. This species can fly very slowly in clutter and that it hunts by slow hawking and/or by gleaning (Tejedor 2011).

Threats [top]

Major Threat(s): Threatened by cave issues (mining and tourism), as well as by activity of hurricanes and volcanic eruptions on small islands.

Conservation Actions [top]

Conservation Actions: Its apparent requirement for humid caves, points to a limited availability of suitable habitat and therefore to a potential vulnerable status. Therefore, it is important to protect these caves.
