Black-winged Little Yellow Bat

Order: Chiroptera
Family: Vespertilionidae

 

Conservation Status: Least Concern.


Four or five Black-winged Little Yellow Bats, piled onto a scale, would weigh only about an ounce. These tiny bats leave their roosts at sunset and are often seen flying close to the ground, pursuing small, flying insects. Shortly before dawn they have a second peak of activity and go out hunting again. They are found in a variety of habitats, including forests, open areas, and settlements. They roost in buildings and hollow trees.
