These pictures are from the Congress Street Bridge in Austin on Sunday, April 23rd. Jamye and I stood in the bat observation area adjacent to the Austin Statesman newspaper's parking lot with several other onlookers. The bridge was jam packed on the east side to watch the exodus of over 1 million Mexican free-tailed bats. I manipulated some of the pictures in Photoshop because the lighting at dusk was obviously not ideal. Click on the pics to see them a little bigger.

Those black streaks? Bats.
Used the flash here to bounce off the underside of the bridge and some bat bellies (white shapes on the right). Remember those black streaks? Fast bats.
