Bats fall into two categories: those that migrate to warm climates when it gets chilly and those that hibernate during cold months. Our Bat of the Day, the spotted bat, is a migrator, which means their natural range extends from British Columbia, Canada, south through the western United States and into Mexico.

These bats are considered rare, but what a treat to see one! They have the largest ears of any North American species, and those pearly pink ears and black and white spotted fur give it a very distinctive look. When resting, the spotted bat curls up its ears around its head, but when the bat becomes active, they inflate with blood and unroll.
You also can hear them! Some bats use sound waves (called echolocation) to navigate the night sky or find food. The bats make a high-pitched sound, almost always too high for humans to hear. That sound bounces off solid objects and sends echoes back to the bat. From the echoes, bats can determine size, shape, etc. the spotted bat has one of the only echolocation calls that humans can hear.
