Free-tailed Flights of Fancy

Experience a fabulous flight of Mexican free-tailed bats during Bat Loco: Tuesday, Aug. 7, from 6-9 p.m. near the Camden Street Bridge.

The home of the largest colony of bats in the world is located just 20 miles north of San Antonio — in Bracken Cave. The wee little bats that live there save South Central Texas cotton farmers about $750,000 a year on pest control!

Bracken Cave is especially important because it’s a maternity colony. Every spring, about 10 million Mexican free-tailed bats migrate from various caves across Mexico to San Antonio.

Every night, the bats emerge and fly over 60 miles in one night to catch bugs. In mid-June, the mother bats have their babies. The babies then start flying around mid to late July, bringing the emergence count to almost 20 million bats. It takes up to four hours for all of the bats to exit the cave and fly off into the night.

You can experience a similar emergence during Bat Loco Tuesday, Aug. 7, from 6-9 p.m. near the Camden Street Bridge on the Museum Reach segment of the San Antonio River Walk.

This free family-friendly event features food, games and lots of batty activities — and, of course, the famous free-tailed flight!
