Baby Mexican Free-Tailed bat hangs upside down.
A juvenile Mexican Free-Tailed bat hangs on the cave wall at the entrance to Bracken Cave. Bats arrive at Bracken Cave in March from Mexico, where they spend the winter. The bats mate before they migrate, but the males depart to form separate bachelor colonies. The pregnant females move between about a dozen caves within a 100-mile radius of San Antonio, with the largest colony inhabiting Bracken Cave.Add to Lightbox Download
