A couple of day's ago my adult son asked if any hummingbirds had purple on them. He saw what he thought was purple on a hummer trying to access a feeder on our patio, only to be instantly chased off by a rufous. I watched on and off for the rest of the day, but never saw it. With a couple of recent obol reports of Costa's, he could have actually seen one. He knows what Anna's and rufous hummers look like. Wish I'd seen it to be able to verify, plus it'd be a first for my yard!
