what is it?
The Mexican free-tailed bat or Brazilian free-tailed bat ( Tadarida brasiliensis ) is a medium-sized bat native to the Americas, regarded as one of the most abundant mammals in North America. Its proclivity towards roosting in huge numbers at relatively few locations makes it vulnerable to habitat destruction in spite of its abundance.
