The plumage of a male wood duck is among the finest in North America. Iridescent greens, purples, and blues across the head and crest, with bold white stripes and red eyes. During breeding season, this helps attract a mate, although the coloring remains the same throughout the year. This guy was photographed just outside of Vancouver. Nikon D800 with Nikkor 200-400mm lens (at 400mm) ISO 640, f/4 at 1/1000th of a second.
