The Northern Long-Eared Bat is a medium-sized bat native to North America. It is known for its long ears, which can be as long as its body. This species primarily roosts in forests and is often found in tree cavities or under loose bark. They feed mainly on insects, using echolocation to navigate and hunt in the dark. This bat has faced significant population declines due to the spread of White-nose Syndrome, a fungal disease affecting hibernating bats. As a result, the Northern Long-Eared Bat is listed as a threatened species under the Endangered Species Act. Conservation efforts are underway to protect its habitat and promote recovery.
