Pat those are some nice captures! What time of day was it? These were taken with a 400mm? Are they heavily cropped or was he close to you? I know from my birding that for some reason its easier to get closer to these guys when theres alot of activity going on.. here in CT they tend to be largely alone and standoffish . Its hard to get close unless they are focused on eating. Sometimes if they are eating they will be right in front of you and not even care.
