Waiting the nightly bat exodus. Austin.TX

The Congress Avenue Bridge is home to the largest urban bat colony in North America. Nearly 1.5 millions Mexican Free-tailed bats reside in vertical crevices beneath the bridge.The bats provide a valuable environmental service to central Texas by consuming 10-15 tons of insects nightly.
