Bats are the only group of mammals capable of flight. Bat wings are made of double layers of skin stretched across a framework of modified finger bones and extend back to the legs. Bats are also well known for their excellent hearing. Mostly nocturnal, bats use echolocation to locate prey in the dark.

Bat Species


Bats - family Verspertilionidae


Long-legged Bat
Myotis volans

These bats have uniformly-colored light brown to dark brown fur, including a strip of fur on the underside of the wing from elbow to knee. Long-legged Bats prefer coniferous forests near water sources, and eat moths, flies, and beetles. In winter they hibernate in caves, while in summer they roost in trees, rock crevices, and buildings.


Silver-haired Bat
Lasionycteris noctivagans

Silver-haired Bats have black fur, but their "silver" appearance comes from longer, white-tipped hairs on the back. These bats are found primarily in forests and forage relatively low to the ground, often over lakes and other water sources. They eat flies and moths.


Yuma Bat
Myotis yumanensis

Yuma Bats have brown to black fur on the back with paler undersides. They prefer meadows and open areas near water and much of their preferred food is made up of aquatic invertebrates, such as caddisflies, mayflies, and midges. These bats are active at dawn and dusk.
