Description
Found mostly in caves, but also under bridges and in abandoned buildings, the mexican free-tailed bat is an insatiable moth-eater. It lives in enormously large colonies and it's one of the most sociable bat species. The largest colony, boasting 20 million individuals, is located in Bracken Cave in Texas. The mexican free-tailed bat is a very fast flyer - it can reach the horizontal speed of 100 miles per hour.

Feeding Habits
Mexican free-tailed bat, an insectivore, utilizes echolocation for hunting moths, beetles, dragonflies, and other flying insects, often at high altitudes. Their predation on migrating insects in Texas is notably substantial.
Habitat
Mexican free-tailed bats roost primarily in caves. However, they also roost in buildings of any type as long as they have access to openings and dark recesses in ceilings or walls. Caves, though, need to have enough wall and ceiling space to fit millions of bats. Before buildings, free-tailed bats in the Southeastern United States probably roosted in the hollows of trees such as red mangrove, black mangrove, white mangrove, and cypress.

Migration Overview
Mexican free-tailed bats in southeastern Nevada, southwestern Utah, western Arizona, and southeastern California come together to migrate southwest to southern California and Baja California. Bats in southeastern Utah, southwestern Colorado, western New Mexico, and eastern Arizona travel through the western edge of the Sierra Madre Oriental into Jalisco, Sinaloa, and Sonora. Some bats that summer in Kansas, Oklahoma, eastern New Mexico, and Texas migrate southward to South Texas and Mexico. Some bat populations in other areas of North America do not migrate, but are residents and may make seasonal changes in roost sites.

Bird food type
Behavior
Mexican free-tailed bat is a highly gregarious species, with colonies often reaching millions within confined spaces. Nocturnally active, they engage in aerial insectivory, reducing insect populations significantly. Mexican free-tailed bat is migratory, with greater distances covered by northern populations. Their echolocation abilities facilitate their nocturnal insect-hunting behaviour, an adaptation unparalleled in precision.
Species Status
Though abundant and widespread, some local populations have prompted protection and conservation efforts.
