Rare in migration here. Two individuals were seen together, both first-winter plumage, so I am not sure whether these two photos represent one, or two, individuals.
Sailor Bar.
Most like a Myrtle, but note the yellow on the throat (2nd photo) and the presence of an anomalous thick short white brow instead of a linear white eye line. Sacramento Bar.
Third photo was totally backlit, so maximally lightened in order to demonstrate some features.
American River Parkway.
