This is the best part of our King Ranch tour. A pair of Crested Caracara. Not as clear as I would like through the tour bus window, but "OK".
We saw a few more while driving down here, but they either spooked when we stopped, or were flying and we couldn't get a clear shot.
As Stormy commented below, they had a young one on the ground that we didn't see untill we were under way. I fired off a shot, but it didn't turn out well.
