Single Swan Swimming
The Trumpeter Swan (Cygnus buccinator) is the largest species of water fowl. This specimen at the Calgary Zoo is a fine example. Of course there is very little color in the swan itself other than black and white. The Trumpeter has a black bill and lores and the back ground colors seemed distracting to me. I converted the image to monochrome with Color Efex Pro 3.0 in Nikon Capture NX2.
