Turning Heads

The Gambel's Quail is a handsome fellow, no doubt about it. But even he did a double-take when a Hooded Oriole appeared at the fountain behind Desert's Edge.
This was a first for my bird life list. A few days later, I thought the Hooded was back, but it turns out it's another lifer, the Bullock's Oriole.
Notice that the Hooded has an orange hood the color of butternut squash, and a black face and bib. The Bullock's, which is the Western version of the Baltimore Oriole, is yellow, with a black cap and black line through his eye.

Now the test. What is this?
