Happy Halloween: Bats!

To help celebrate Halloween here are some bats!

The Big Brown Bat, Eptesicus fuscus, is the most common bat in our area. They are easily seen at dusk flying around parks and water sources as they search for their insect food. We're putting up a  bat box in the North Campus in hopes that some of these bats will move in.

The Hoary Bat, Lasiurus cinereus, is another species often found in L.A. This specimen was collected at the Museum on the cafe patio a few years ago.

Last but not least here's the ghost-like Pallid Bat, Antrozous pallidus. Even though this species of bat is rarely found in the urban core, it is found in the desert regions surrounding Los Angeles. Unlike the Big Brown Bats these bats capture their food on the ground! They locate their prey by finding a perch and listening for insect footsteps (note the massive ears). When the right vibrations are heard they swoop down catch the unsuspecting insect and return to the perch to devour it!

Thanks to Jim Dines, the Museum's Mammology Collections Manager, for allowing me to photograph these awesome creatures!
