Dinner on the Fly Though small (four to five inches long, on average), big browns consume an unbelievable amount of food, including moths, flies, beetles, mosquitoes, and even wasps. A single animal can gobble up a third of its weight in one night. This natural form of pest control is vital to reducing insect populations that plague crops, as well as those that carry diseases harmful to humans.
"Going Batty" The long-lived phrase comes from the aerodynamic critters’ often-erratic flight—their habit of making sudden turns and twists while chasing prey. The bat’s wings are flexible, with muscles that allow them to move more like human hands than bird wings, which operate as single units.
Health Scare Across the country, bat species that hibernate (including big browns) are dying at an alarming rate from white-nose syndrome, a disease that was found in South Carolina in 2013 and has been spreading since. The fungus that causes it thrives in cool, humid places with minimal airflow, and while humans aren’t affected by it, they can transport its spores.
Dark Secret Bats are not actually blind, but like all mammals, they cannot see in complete darkness. Thus they use echolocation, creating a steady stream of sounds with their mouths (inaudible to us) that bounce off nearby objects to help them find their way in the dark.
Invite Company Habitat loss poses a major threat to bats across the world. To shelter a colony in your own backyard, install a house that’s certified by Bat Conservation International. Locally, Wild Birds Unlimited is a good source for these boxes that must be hung 12 to 20 feet above the ground.
Safety First While bats are often believed to carry rabies, only one-half percent of them actually have the virus. However, their tiny teeth marks are hard to detect, so if one is found inside with a snoozing human or unattended child, that person should seek medical attention. If possible, have the bat professionally captured and tested for rabies by the South Carolina Department of Health and Environmental Control.
