The Mexican Freetail Bat, also known as Tadarida brasiliensis, is one of the most widely distributed bat species in the Western Hemisphere. They are also known as Tadarida mexicana, Brazilian Freetail Bat, or Brazilian Free-tailed Bat. However, they aren't exclusive to Mexico, as these bats can be found throughout the southwestern United States, Central America, and South America. Mexican Freetail Bats get their name from their long tails, which typically extend beyond their flight membranes. They are insectivores and play an essential role in maintaining balance in the ecosystem by controlling insect populations. These bats are fascinating creatures and are critical to the environment they inhabit.
