Most caves are the host area for thousands of bats. They use the caves during the winter to stay warm and raise their young. They are found near the entrance. The Mexican free-tailed bats may go up to an altitude of 3,000 meters and travel hundreds of miles to feed on insects. Bats use a combination of spatial memory, personalized calls, and personalized odors to identify their young from the millions of other young bats.
Bats migrate from the caves during the summer months.
Bears, raccoons , and bobcats are several of the other cave guests. Troglophiles Salamanders are related to frogs and toads. These salamanders live near the cave entrance. They see well and have colored skin. They like the cave because it is moist and dark.
