Canyon Bat

Canyon Bat

The canyon bat, formerly known as the western pipistrelle, is the smallest bat in the U.S. Canyon bats have short, broad faces and white to yellow fur that contrasts starkly against their black ears, face, and wings. Preferred habitat includes deserts, woodlands, and shrublands from western Mexico north to Washington and as far east as central Oklahoma and west Texas. Small maternity colonies have been reported, but solitary females are also common. The species roosts primarily in rock crevices, and females typically give birth to twins. Canyon bats are capable of extremely slow flight, which has been described as butterfly-like. Diet includes moths, beetles, and flies.
