Black Crowned Night Heron
I've seen these, and this looks like one. I would guess a juvenile, because it seems a tad on the smallish size -- though pics can be deceiving and there's nothing in this one to provide a sense of perspective -- and because of the yellowish cast to part of its bill.
Anyway you can find a very detailed description here:

And your pic fits it exactly. Red eyes, yellow feet, white and black markings, down to the two white "filamentous plumes." In its winter range, probably down from Washington state.
I kill threads. It's what I do.
