As my brother would say: an LBT, little brown thing. I first thought was a sparrow and maybe a pine siskin, specifically. Interestingly, a photo in a local newspaper showed up and I think this is a hermit thrush. The bird was quite loud, another feature of this species of thrush.

Taken with a 600mm telephoto lens steadied on a deck railing near sunset pointing perhaps 20 yards into the tree tops. An amount of software post processing with exposure was also required.
