If you hang out in Austin for any period of time, you’ll notice something - the people here are crazy about bats. There are bat statues, bat murals, and once, Austin even had an ice hockey team named after the bats. So what’s the deal with the bat’s, you ask? Read on friends!
Austin is Home to the Largest Urban Bat Colony IN THE WORLD
That’s right, Austin is home to the world's largest urban colony of bats! Each year in March, over 1.5 million Mexican free tail bats return to the Ann Richards Congress Avenue bridge to birth and raise their young. Surprisingly, the colony is almost exclusively female (minus the young), as the males stay behind in Mexico awaiting their mates return in September. No one knows exactly why the males stay behind, it’s just one of the mysteries still surrounding these amazing creatures.
Bats Eat Bugs
If you’ve ever been outside in Austin in the summer, you might have noticed the bug situation - there are tons of them. Mosquitoes, the scourge of southern summers, are plentiful here and it’s a constant battle keeping them at bay. Each night, Austin’s bat population comes to the rescue, eating some 10,000 - 20,000 pounds of insects, including mosquitoes and other agricultural pests. This free service the bats provide to the city’s human inhabitants is invaluable, and Austinites are very thankful for the critical role they play in the urban ecosystem.
Bats are Entertaining
As it turns out, bats are fond of dramatic exits. Each night, on que, the bats emerge, en masse, from their nests under the bridge to feed. The bats’ nightly mass exodus takes almost an hour to complete and is truly a natural wonder. This spectacle is truly a sight to behold, and onlookers start gathering around the bridge in the evening, jockeying for the best viewing position. When the bats start to emerge, they are so densely packed together that from a distance it can look more like a stream of smoke than a bunch of tiny individual creatures.
