No elevation, no voice? Ouch....
This is a Screech Owl -- the yellow eyes, small size, and black mark at the lower lateral part of the facial disk are sufficient to go that far.
Which one? The bill seems to be a medium blue-gray. An adult Western Screech should have a dark bill (except for the tip), but juveniles have paler bills. Western's should also have prominent dark streaks on the center of the breast feathers. A few are visible at the upper breast here.
Whiskered Screech Owl should have bolder markings underneath, including much more widely spaced crossbars. There is supposed to be a difference in the size of the feet, but I've only seen the feet of one Whiskered and I've never seen a Western, so I can't make that comparison.
Overall, I'll guess juvenile Western, but I figure I've got about a 52% chance of being right, if I'm lucky.
I agree: barring on the belly and lack of ear tufts points to juvenile western screech owl.
