This free-tailed bat was admitted to our facility with a big gash to his side, which included a severe wing membrane tear which rendered him unable to fly. It took several months for his injury to heal. The photos below show the progression of his healing. His membrane healed correctly, and after six months of nightly flight exercise the finally demonstrated the flight skills needed to be returned to the wild. Click photos to enlarge (and our apologies that there are no photos of his face).

This severe gash was likely caused by a hawk or an own.

Within a month his side was almost healed.

A few months later his torn wing membrane regenerated and he was able to begin nightly flight exercise.
