I have dreamed of seeing this bird since I first saw it in Sibleys. I was astounded by its contrasting beauty. I never imagined that when I got to Mount Lemmon the bird would fulfill my wish so completely.

This photo is uncropped. As we stood on the side of the road leading to the Incinerator Ridge parking lot the bird landed 15 feet away on a branch at eye height. It then spent the next twenty minutes collecting nesting material in a 30-yard circumference from us. One of the most exceptional birding experiences I have ever had. I will post more photos of the warbler with the nesting materials, along with a Grace's Warbler busy with the same task.
