New Kids on the Block
Pallid bats are pretty unique! They have very large ears, even by bat standards. As with other species, the large ears help them hear their prey. However, unlike most other bat species, pallids forage for prey on the ground as well as on the wing. Their prey includes large flightless insects which they locate by listening for the sound of insects’ “foot-steps” on the ground. Pallid bats consume a large variety of insects, many as large as 70mm (more than 2 1/2 inches). They also drink nectar and eat the fruit of agave plants in Texas, making them pollinators! Pallids are a western species, inhabiting the arid regions of western North America and Canada, as well as central Mexico.
Spending time with Bo and BD gave us the chance to watch pallids up close for the first time. All the bats we care for come from the wild and are, therefore, truly Wild-Life. However, these desert bats were more proud and independent than most of the bats we see at the refuge. They proved a unique challenge to care for—they had to be monitored very closely to make sure they were eating enough. They never ate a mealworm from our hands. But even tough guys like Bo and BD have a soft side. In their natural habitats, pallid bats roost in colonies. Out in the flight enclosure, Bo and BD cuddled up with Moby, a leucistic Mexican free-tail, and together they were known as the “Pale Males.” They were also completely devoted to each other. Flying around the enclosure, anywhere Bo flew, BD was flying right behind.
Earning Their Wings
After a year of practice, Bo and BD graduated flight school! Sophie, a bat researcher and environmental justice advocate, who happens to be the current Miss Delaware (perhaps soon to be Miss America!), came to visit about that time. She was heading back out to west Texas so she picked up Bo and BD and found a beautiful cliff face full of crevices for the boys. On July 18, 2021, they were released back into their desert home. Just like at Austin Bat Refuge, as soon as Bo took off, BD was quick to follow!
