Selman Bat Cave – 10 tons of insects each night

Selman Bat Watch registration forms available May 28
The sight of at least a million bats emerging into the evening sky is a spectacle that won’t be seen under city lights, but people can still see this nightly event this summer at one of the Oklahoma Department of Wildlife Conservation’s annual Selman Bat Watch events.
These annual summer get-togethers are held every weekend in July at the Selman Bat Cave Wildlife Management Area, where the Selman Bat Cave is used every year by migratory female Mexican free-tailed bats to raise pups. In the evenings, they take flight in mass numbers to feast on literally tons of insects.

Each night’s viewing activities are limited to 75 visitors who are randomly drawn from a pool of mailed-in registration forms, which will be available online at beginning May 28. Hopeful viewers must print, complete and mail their registration form to the Wildlife Department at Bat Watch Program, P.O. Box 53465 Oklahoma City, OK 73152 between May 28 and June 5. Only mailed registration forms post-marked on or by June 5 will be accepted, and instructions for completing the form should be read carefully to ensure correctly completed registration. Successful registrants will receive an e-mail confirmation and a packet in the mail. The cost is $12 for admission ($6 for children 8 – 12 years old).
“Given the popularity of this event, the Department uses this approach to streamline its registration process,” said Melynda Hickman, wildlife diversity biologist for the Wildlife Department.

The Wildlife Department purchased the area around the bat cave in 1996 because of its ecological importance to the Mexican free-tailed bat. According to Hickman, the cave is important because it is one of only four major sites in Oklahoma that is used by females to raise their young.
Hickman says the bats serve as free pest control. The bats spend daylight hours inside the cave. But most of the action is after sunset.
“Studies tell us that the bats at Selman Bat Cave eat about 10 tons (20,000 pounds) of insects every night,” Hickman said.
The bats’ evening emergence is the highlight of a Bat Watch, but there is more to the evening than simply watching bats. Buses take visitors to the Selman Bat Cave Wildlife Management Area, usually closed to the public, where they learn facts about bats and the prairie community. There also is an optional nature hike before the bats emerge.
Additionally the Bat Watches benefit the local economy by drawing tourists from a multi-state region into Oklahoma. Hickman said Oklahomans enjoy a rare opportunity to get close to wild bats and to share their importance to the environment and the economy.
