Incredible shots, Joe! I am so jealous!! Need any volunteers to help in the research??? That would be a dream come true! My wife & I look forward to every January when we travel about an hour from our home to a little town called Grafton, Illinois to see the balk eagles that winter here on the Mississippi north of St. Louis. The closest that I've gotten is the base of a couple trees where they are perched but nothing compared to what you are able to accomplish!
Keep on the good work & excellent shots!
