Northern Long-eared Bat

Myotis septentrionalis


Northern long-eared bats are small and catch insects both in flight and picking them off plants. They hibernate underground in winter and live in tree cavities in summer. Due to population declines from white-nose syndrome, they are listed as threatened in the United States and endangered in Canada.

Fun Facts

They are called “whispering bats” because they can echolocate very quietly to sneak up on insects that can hear normal echolocation calls.

For hibernation, northern long-eared bats increase their body weight by 45% to survive the winter months.

Their wings are shaped differently than other bats, making them slow flyers but very good at navigating through forests and hovering to catch insects on plants.
