Tadarida brasiliensis, commonly known as the Brazilian free-tailed bat, is notable for its long, slender tail that extends beyond its tail membrane. It inhabits diverse environments, from urban areas to forests across the Americas. This bat is renowned for its high-speed flight and large migratory colonies, contributing significantly to insect population control.

Tadarida brasiliensis, commonly known as the Brazilian free-tailed bat, is native to the Americas. Its geographical distribution extends from the southern United States through Central America and into parts of South America, including Brazil, Argentina, and Chile. This species is also found in the Caribbean islands.

The Brazilian free-tailed bat typically inhabits diverse environments, ranging from arid deserts to humid tropical forests. It often roosts in large colonies in caves, buildings, and under bridges. The species is highly adaptable, thriving in urban areas as well as natural settings.

Tadarida brasiliensis is primarily insectivorous, playing a crucial role in controlling insect populations, including agricultural pests. Its ecological niche also involves rapid and high-altitude flight, which allows it to cover large areas while foraging. The species exhibits a strong capability for long-distance migration, particularly populations in the United States that migrate seasonally to warmer regions in Mexico and Central America.
