This is a video from Bracken Cave in San Antonio, Texas of some of the 20-million Mexican Free-tailed Bats that roost in the cave from March to October leaving the cave to go hunting one evening (previously: 3 million bats leaving a cave in Malaysia). FUN FACT: Did you know bats are really just birds that were conceived after dark? Because that's 100% true and you should teach your children that.
Bracken holds one of the largest concentration of mammals on earth. The emergence of these millions of bats, as they spiral out of the cave at dusk for their nightly insect hunt, is an unforgettable sight.
Whoa -- the bats in the cave make up the largest concentration of mammals on earth? That's impressive. Before learning that I thought the honor went to my apartment building. There's only like 22 units I swear at least 1,200 people live here. I've never seen the same person twice. Except once, and he second time they were wheeling him out dead.
Hit the jump for the video, then let's head down there and say what's up to Bruce Wayne.
Thanks to Ashley SC, who informed me her patronus is a bat. That's awesome, mine's a penguin.
