Ken, this is superb. great colors on the bird and a wonderfully sweet BG. Loved the comp and excellent sharpness. It must be so hard doing flight photography in these conditions...birds so close and in a moving vehicle. I remember reading that as soon as the vehicle stops they go away....so fascinating.
The bird looks great against that green BG, and the sharpness is good. I would have preferred better wing position and a slight head turn towards the viewer. I'm sure this must have been a tough capture when taken from a moving vehicle!
