More Back Yard Wood Ducks

I shot this wood duck early this morning out of my bedroom window just as the sun was coming up. He was one of 30+ wood ducks scurrying around my back yard hunting for acorns (which they gulp down whole). As many as 45 or 50 are coming up into my yard morning and evening multiple times until they are satisfied with their haul. They are difficult subjects. They are very wary and almost never still as they forage. No flash as they will not tolerate it. They are backlit at these times to compound the difficulty. These are fun times in the old back yard, though.
Grainy look is due to ISO 800. Cropped left and right. Nikon D2h, 500mm AF-S, LF JPG, Aperture Mode, 1/50th @f8.
