Myotis lucifugus
As suggested by the bat’s name, its fur is uniformly dark brown and glossy on the back and upper parts with slightly paler, greyish fur underneath. Wing membranes are dark brown on a typical wingspan of 22–27 cm (8.7–10.6 in). Ears are small and black with a short, rounded tragus. Adult bats are typically 6–10 cm (2.4–3.9 in) long and weigh 5–14 grams (0.2–0.5 oz). Females tend to be larger than males. The fore and hind limbs have five metapodials. The skull of the brown bat lacks a sagittal crest. Its rostrum is shortened and has upslope profile of the forehead. Its braincase flattened and sub-circular when observed dorsally. The bat has 38 teeth all of which including molars are relatively sharp, as is typical for an insectivore, and canines are prominent to enable grasping hard-bodied insects in flight. The little brown bat can be distinguished from the Indiana bat by the absence of a keel on the caclar and long hairs on the hind feet that stretch longer than the toes. Compared to the long-legged bat, the brown bat has a shorter tibia and lesser amounts of ventral wing hair in addition to the lack of a keel on the caclar.
This little guy was found in a canal we went in on a jeeping trip. Don't worry, the bat is okay. He might just be a little cold and tired.

Oh, thanks Searra. I was thinking that he was a Short Eared bat. Couldn't know for sure though.
No we found this bat hanging low in a canal we were jeeeping in. This cute little genius was just cold. No one likes getting out of bed :).
Is it dead?
