Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2016
Date Assessed: 2015-05-04
Assessor(s): Solari, S.
Reviewer(s): Battistoni, A.
This species is listed as Least Concern since, although its extent of occurrence is relatively small, it is a relatively common species and it is unlikely to be declining at a rate that would even nearly qualify it for listing in a threatened category. However populations on Bonaire and Curaçao are under threat from habitat conversion due to tourism and development.
Previously published Red List assessments:

Geographic Range [top]

Range Description:This species occurs in the northwest Venezuela, and Curaçao and Bonaire Islands (Netherlands Antilles) (Simmons 2005), and it may also be in Aruba. It is also found in northeast Colombia (Muñuz G. and Mantilla-Meluk 2012, Solari et al. 2013).

Population [top]

Population:The species might be locally common (Solari et al. unpubl. data), however it has a restricted range.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Curacao Myotis is strongly insectivorous, feeding especially on small aerial insects (e.g., flies or moths) that they catch in open semi-arid areas. It is generally found in small colonies (Linares 1998).
Continuing decline in area, extent and/or quality of habitat:No

Threats [top]

Major Threat(s): On islands, the species is under threat from habitat conversion to tourist resorts and general development. Within the Caribbean coast of northern South America, changes in land cover are minimal (mostly caused by small herds of cattle and goats).

Conservation Actions [top]

Conservation Actions: The species needs conservation attention in island parts of its range.
