Backyard Arizona bird with thin beak and black half-circle on breast

Saw a new bird in our backyard today in Phoenix, and have no idea what it is. We heard an odd squawk, and saw this fellow perched on our hummingbird feeder trying to get a drink.

He flew away before we could grab a camera, but he had a long, thin beak (he could get at the hummingbird nectar). The top of his head was smooth, and looked like it was a faint red or orange color. He had a distinct black half-circle on his breast, and it looked like the rest of his belly was dappled. Possibly tan wings, but was hard to tell in the morning light.

We've been curious, and had no luck browsing pictures on line, so any help is appreciated!
