A few weeks ago I was at Sweetwater Wetlands, a manmade wetlands here in Tucson that is part of the sewage treatment and water reclamation plant. I photographed both of these vermillion flycatchers by an artificial stream right at the entrance. The one on the right is the typical coloration but the one on the left (I found out later) is a leucistic or white morph, much like white lions or white tigers (except without the inbreeding).
