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. These bats primarily feed on insects, using echolocation to navigate and hunt in the dark. Unfortunately, the northern long-eared bat has been significantly affected by white-nose syndrome, a fungal disease that has led to drastic population declines across its range. Conservation efforts are underway to protect this vulnerable species.
