Safety note: May carry rabies — do not approach or handle.
The Brazilian Free-tailed Bat forms the largest known mammal aggregations on Earth, with Bracken Cave in Texas hosting up to 20 million individuals. It is among the fastest bats in North America, capable of reaching 100 mph in level flight, and migrates hundreds of miles between summer and winter roosts. A single colony can consume 200 tons of insects per night, providing enormous agricultural pest-control services.
