Geoffroy’s Tailless Bat, Anoura geoffroyi
Geoffroy’s tailless bat (Anoura geoffroyi) can be found in the American tropics, and is a species of New World leaf-nosed bats, or Phyllostomidae family. Its range extends from northern Mexico to many areas of Central America and across northern portions of South America. Its range also stretches from Peru to areas of Brazil and Bolivia. Some populations have been found in Grenada and Trinidad. This bat prefers to live in habitats at elevations between 1,300 and 8,200 feet. It can be found in pine, oak, and clouded forests as well as agricultural lands. There are three recognized subspecies of this bat.
Geoffroy’s tailless bat is considered a medium sized bat, with an average body length of 2.8 inches and weight that ranges between 0.35 and 0.53 ounces. Most of its fur can range from black to darker brown, while the upper parts are brownish gray and the neck and shoulders are silvery gray. The wings are typically dark brown. As its name implies, Geoffroy’s tailless bat does not have a tail. Its muzzle is long and its tongue is built for extracting nectar from flowers.
As is typical with bat species, Geoffroy’s tailless bat is nocturnal and prefers to spend the day resting in caves with a nearby water source. It can live alone or in groups of up to three hundred, although the typical size of a colony is between 20 to 75 individuals. It is an adept flier, and will use its sensitive hearing and echolocation to move about and forage.
The main diet of Geoffroy’s tailless bat consists of beetles and moths, but is has been known to eat nectar, pollen, and fruits. In some areas of its range, it is known to eat only nectar. This bat will avoid competition with other bats in its range by foraging for food in separate altitudes that are undesirable to most bats.
Mating season for Geoffroy’s tailless bat typically occurs between the months of March and August. This period coincides with the rainy season and allows the mother to nurse better because of abundance in food. After about four months of pregnancy, one pup is born, but birth months do vary depending on the bats location. Geoffroy’s tailless bat has been given a conservation status of “Least Concern” on the IUCN Red List.
