I got lucky with this guy sitting there for about 10 minutes only about 40 feet away. I was all set up to catch him taking off when a guy walked up with his dog. I turned my head for a second to say something to the guy and the hawk knew he had me - gone! :? This was taken with my 70-300mm lens at 300mm and it shows why I am dying to get a 500 or 600mm lens.
