Aix sponsa. This is our native variety of Wood Duck. They are not particularly common. I found this one on an island in the Santa Cruz River at Ina Road in Tucson, Arizona. He was the only one there. This year, a year later, there are five males and four females in a similar location. They were hunted nearly to extinction for their beautiful feathers, and are making a comeback. The female on the left is another species of duck.
