Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2008
Date Assessed: 2008-06-30
Assessor(s): Barquez, R., Perez, S., Miller, B. & Diaz, M.
Reviewer(s): Medellín, R. (Chiroptera Red List Authority) & Schipper, J. (Global Mammal Assessment Team)
This species is listed as Least Concern because, although it is seldom recorded, it has a relatively wide distribution, is tolerant of a broad range of habitats, has a presumed large population, 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)

Population [top]

Population: Rare, three specimens found in three localities to southern cone. Little work has been done on this rare species, therefore the range may be larger than what has been documented. (Greenhall et al., 1983)
Current Population Trend: Unknown
Additional data:
Population severely fragmented: No

Habitat and Ecology [top]

Habitat and Ecology: Found in forests and transition zones. Hematophagous. D. youngi has been found in moist tropical and dry forests. They have been found roosting in caves, tree hollows, and on the edges of banana tree plantations. (Elizondo, 1999; Nowak, 1999). White-winged vampire bats feed mostly on blood from various bird species, including free-ranging poultry species (chickens, Guinea fowl, and turkeys). (Nowak, 1999; Schutt et al., 1999)
Systems: Terrestrial

Threats [top]

Major Threat(s): Can be confused with the common vampire bat (D. rotundus) and be persecuted.

Conservation Actions [top]

Conservation Actions: In Mexico is listed as subject to special protection under NOM - 059 - SEMARNAT - 2001 (Arroyo-Cabrales pers. comm.).
Found in protected areas.
