A pretty wee bird, George, with good focus on his head. You must have used a very low f-stop, I'm guessing. The bokeh is good as well and there's just enough light bounce from his perch to his chest to softly illuminate him.
If you've ever wanted to make a difference but found it hard to believe that one person could... check out the Kiva Team Caedes discussion thread and discover that anything is possible.
Indeed f.4.5. 200 mm Nikon macro lens. The bokeh is decent. Unfortunately, it was shot through bay window so there is glare to the viewers left of tail feathers. Beautiful bird!!
