Swainson's Hawk Flying Overhead

I was just able to get my lens up in time to catch this hawk passing by overhead. I had changed lenses to a 200-500mm and was hoping to see some birds; this one was a nice immediate reward. It wasn't long before it flew out of sight, and only a few images actually turned out, but I am glad they did, as it's always a challenge to get good, sharp shots of a bird flying like this.
