These are bluejays. Or mountain jays, to be specific. They were either friendly or mating. I'd suspect the latter since they don't often seem very friendly.
A bit later this big-breasted robin showed up.
He took an interest in the bird bath.
Apparently being accustomed to such appliances, he knew that fresh cold water wasn't just for drinking.
Having splashed most of the water out onto the ground, he turned and glared at me, as if to say "Hey, do I stare at you when you take a bath?"
