Review:

Every summer, Bracken Cave provides home to over 15 million Mexican free-tailed bats (Tadarida brasiliensis). It is the largest bat colony in the world and one of the world’s largest concentrations of mammals.

Every day, at dusk, millions of bats fly out of the cave to hunt insects, providing a spectacular sight popular among locals and visitors to San Antonio.

The cave is located about 20 miles from downtown San Antonio, and is under constant threat of urbanization.

To prevent the cave from being swallowed by subdivisions, in 1992 Bat Conservation International (BCI) bought the land on which the cave is located and, with its conservation partners, continues to purchase additional land around the cave.

Their goal is to protect not only the bats, but also other endangered and native species found on the Bracken Cave Preserve.
