This drake and two hens were scouting around for a suitable nesting hole, up in some dead trees. They were VERY picky. Fascinating to watch - maybe a video next time.
1DM3, 500 mm x 1.4TC, ISO 320, 2/3 stops below evaluative: f/5.6, 1/2000. PP: cropped 50% of full frame, removed some BG branches, USM 120/0.3/1 on bird and perch.
I like the calling pose and eye contact and would try to get more details in the blacks. I would also tone down the whites a bit. It looks as if you ran NR only in the large blue area.
