Big Brown Bat

The big brown bat is a species of vesper bat distributed widely throughout North America. It was first described as a species in 1796.

 

Compared to other microbats, the big brown bat is relatively large, weighing 15–26 g and possessing a wingspan of 32.5–35 cm.

 

Big brown bats are insectivorous, consuming a diverse array of insects, particularly night-flying insects, but especially beetles. Some of the beetles it consumes are serious agricultural pests, including cucumber beetles. They are nocturnal, foraging for prey at night and roosting in sheltered areas during the day such as caves, tunnels, tree cavities, and human structures. Their breeding season is in the fall, shortly before their annual hibernation. After hibernation ends in the spring, females form maternity colonies for giving birth to young. Oftentimes only one offspring is produced per litter, though twins are common in the Eastern US.

 

Lifespans of 6.5 years are considered average.

Very nice to see one close up.

Was with Richard and Robin when we saw the bat fly.  We were lucky to see it land.
