Whoa, look out! We’re talking about the Townsend’s Big-eared Bat this !
This bat is found broadly across the American West and forms maternity roosts, like the one pictured here, in ideal temperature and humidity conditions to rear their young. Roosts are usually established between March and May and pups are born from May to July. Female bats have one pup per year, and these small mammals are able to fly by their third week of life.
As their name suggests, they have giant ears that can be up to 38 millimeters long, reaching the middle of their body when folded and tucked in. These ears give them a keen sense of hearing, help them regulate their body temperature, and even assist during flight.
These agile fliers consume moths and other insects but face pressure from humans directly killing them or destroying/disturbing roosts. Some folks might find bats scary, but they have an important place in the ecosystem!
Have you stumbled upon a maternity roost or seen a Townsend’s Big-eared Bat flying in the night sky?
