Bats are mammals whose forelimbs form webbed wings, making them the only mammals truly capable of sustained flight. By contrast, other mammals said to fly, such as flying squirrels and gliding possums, can only glide for short distances. Bats do not flap their entire forelimbs, as birds do, but instead flap their spread-out digits, which are very long and covered with a thin membrane.
70% of bats consume insects, sharing a large part of natural pest control. There are also fruit-eating bats; nectar-eating bats; carnivorous bats that prey on small mammals, birds, lizards and frogs; fish-eating bats, and perhaps most famously, the blood-sucking vampire bats of South America.
These creatures, much like many other Mexican animals, can be found almost anywhere in the world, except the polar regions and extreme deserts. To survive the winter some species of bat migrate, while others hibernate.
The Mexican free-tailed bat, also known as the Brazilian free-tailed bat, is a medium-sized bat that is 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. The bat is considered a species of special concern in California as a result of declining populations.
Bat watching, a niche market with ever-growing potential, can be experienced throughout Central America, however, if you choose to rather have a swim with sea turtles, or even a swim with whale sharks, that would be understandable, as scuba diving in Mexico is still one of the most sought-after activities for travelers to the region.
