I was down at the Clayton County Nature Center yesterday and I had been chasing this guy down that fence railing for several feet trying to get a good shot. Finally he stopped for a few seconds, puffed his neck up and this is what I got. For you photographers, 55-300 lens at 300mm, f/5.8, 1/2000sec, ISO 400. This was under some trees and the wide open lens accounts for the tail being out of focus.
