10MAR2006: Bats taking flight, Austin, TX.
Nikon D70, f3.8, 1/800s
In a "happy accident" of civil engineering, Austin's Congress Avenue Bridge contains a slotted bottom that is a perfect fit for bats and the bridge has been adopted by 1.5million Mexican free-tailed bats, making it the largest urban bat colony in the world. They take flight each night at dusk and ascend in a column from the bridge. It's an awesome sight to witness. More info available here.
