Physical Description

Species Lasiurus borealis

The Red Bat is 10.8 - 12.5 cm (4.3 - 4.9 in) in total length. The Red Bat varies from brick to rusty red. It has a thickly furred tail membrane .

Habitat

Red Bats spend their days hanging under the protective cover of tree leaves and clumps of Spanish Moss. The area directly beneath the roost must be unobstructed to allow the bats an easy drop at the beginning of their flight. Roosts are usually near a forest edge or body of water . The Red Bat typically roosts at heights of 1.5 - 6.1 m (5 - 20 ft ).

Typically found at an altitude of 0 to 3,333 meters (0 to 10,935 feet).[1]

Biome: Terrestrial

Diet

Small beetles and moths.

Reproduction

Breeding occurs in autumn, and young are born the following spring . The Red Bat generally has four, more than any other bat in North America. Young are able to fly within 3 to 4 weeks. As with all bats the females carry the young only to move them to another roost. Females roost singly in both species and do not gather with other pregnant females to form a maternity colony ."

Behavior

Various hawks and owls, Blue Jays, and Rat Snakes are known to prey on these bats.

Similar Species

The Seminole Bat is indistinguishable in body size and shape from the Red Bat, but its fur is usually bright reddish orange to chestnut or rich mahogany brown, rather than the brick or rusty red of a Red Bat. The Northern Yellow Bat is a yellowish brown, and it has fur only on the basal (anterior) one-third to one-half of the dorsal surface of its tail membrane, rather than all the way to the edge as the Hoary Bat and Red Bat do.
