Photo taken by Debbie Castro- April 2011 in Cottonwood, AZ.

We think this is a Bullock's Oriole-

A link to All About Bird's shows an image that appears to be the same bird.

There are two photos below---a copy of the orginal photo and a digitally enhanced photo....

The second image here has been digitally enhanced for a better view of the colors and contrast. JS
