This bird seems to be right on the edge of American vs Hybrid and is currently under review locally.
I was trying to catch a single picture of these birds and finally was able to get a few atop a cactus feeding on the buds. They had gray feathers with a white tip on the bottom of their wings.
Captive/‘local’ pair at Hollywood Forever Cemetery.
Something wrong with this poor little thing. I was able to get close and probably would have been able to touch it.
