Free-Tailed Bats and Mastiff Bats: Molossidae

With molossids spread out all over the world, they are found living in a wide range of habitats. They are commonly found in both natural and urban areas. These bats are most plentiful in arid (extremely dry) and semi-arid conditions. They prefer to live in temperatures that are at least 110°F (43°C). These bats roost (rest or settle) in sites such as caves, tunnels, buildings, hollow trees, foliage, decayed logs, and holes in the ground. They also shelter under bark, rocks, and iron rooftops.
