The Bracken Bat Cave Preserve is operated by Bat
Conservation International. The Cave is home to a maternity colony of
Mexican Free-tailed Bats. It is one of the largest known
concentrations of a single mammal species on Earth. From late March
thru October, there are approximately 8-10 million adult female bats
roosting in the cave. When their young are born, that number doubles
to an astounding 15-20 million individuals. It can take hours for the
bats to leave the cave at night and the flight is a true spectacle.
The bats rise out of the cave in a spiraling motion, and stream off to the
south to feed. When they return in the morning, they come back from
all directions, fold their wings, and zip into the cave. The noise of
their wings sounds like rushing water. Numerous predators show up
routinely to take advantage of the bounty; hawks, owls, snakes, raccoons,
and other critters are common near the mouth of the cave. The preserve
is also home to the endangered Golden-cheeked Warbler.
