Wood duck drake

I photographed this wood duck, which is one of my favorite birds, at White Rock lake park in Dallas. It is a large, very nice urban park with lots of birds and smaller mammals. In case you're wondering about the crop I decided that since he was moving toward me AND to my right I would leave him room both to the right and in the front (or in this case bottom of the frame) to move into. I got as low an angle as possible without lying in bird crap and mud to get the shot. It was late and the sun was sinking rapidly and my camera meter does not work with my old lens so I was kind of guessing at the exp so the shot was bit underexposed. This is 47% of FF.
