American Wood Duck
I came across this American wood duck (Aix sponsa) last time I visited the USA (May 2005).
This picture does not have the most artistic composition but it isn't any crop (just a resized full image) so I can't improve much on that. However, I think this close-up portrait shows the beauty of this bird very nicely! I can't keep it for myself anymore, so here it is, I hope you like it!
