Exhibit Dispels Some Batty Myths

Bats are a mystery to most people, the objects of myth and superstition. A new exhibit, opening Saturday at the Natural History Museum of Los Angeles County/Burbank, attempts to dispel some of the misconceptions about these storied mammals.

“Masters of the Night: The True Story of Bats� uses special effects, interactive displays and lifelike settings--including a rain forest and bat cave--to give visitors an appreciation of the bats’ world.

Roosting habits, hibernation and other behaviors are depicted in a re-created bat cave, while a rain forest setting shows the creatures in the wild at dusk, and a visit to a bat nursery shows how mothers care for their young.

Bats are the most important natural enemies of night-flying--and often crop-destroying--insects. But nearly 40% of American bat species are threatened or endangered, according to the museum. The exhibit runs through Jan. 16. Call (818) 557-3562.
