White-winged Vampire Bat, Diaemus youngi

The white-winged vampire bat (Diaemus youngi) is the only species in the genus Diaemus. Its range extends from Mexico into southern Argentina, and includes Isla Margarita and the islands of Trinidad. Approximately thirty bats were found in a hollow tree in Trinidad, and one individual was found in a well-lit cave with two other species of bats.

The white-winged vampire bat is so named because of the white tips located on each wing, and these are easily seen when the bat is in flight. These bats are not as agile while on the ground as the common vampire bat, but they are skilled climbers. It prefers the blood of birds to that of mammals and is a vocal species with an audible range of vocalizations. In Trinidad, it is a known disease carrier. The white-winged vampire bat appears on the IUCN Red List with a conservation status of “Least Concern”.
