The largest urban bat colony lives under the Congress Avenue Bridge in Austin, Texas.
The colony is made up of an estimated 2.0 million Mexican free-tailed bats!
Now look at the 2 million bats emerging from under the Congress Avenue bridge to consume over 30,000 pounds of insects per night. Amazing!
In this video you even here the bats screaming!
Finally a video of one of the 100’000 ecotourists visiting the bridge each year:
Impressive phenomenon and animal behavior!
