From Bat World:

Albino bats are exceptionally rare and have been found in only 4% of the the known bat species. They are spotted only once every 7 to 10 years in the wild.

Free-tail bats can live up to 20 years and eat over 20-million insects in their lifetime, including flying ants, flying termites and corn-borer moths.

These tiny bats can fly up to 10,000 feet high, go as fast as 100mph with a tailwind, and can migrate over 1,500 miles one way.
