Ruddy Duck, San Joaquin Wildlife Sanctuary, Irvine, CaliforniaHere’s one for the duck fans out there. As far as ducks go, the ruddy duck is one of my favorites, especially males like this one in his summertime breading plumage, which includes the chestnut feathers and sky blue bill. Photographed at the San Joaquin Wildlife Sanctuary in Irvine, California. Nikon D800 with Nikkor 200-400mm lens (at 400mm) ISO 800, f/4 at 1/5000th of a second.
