Lucy's Warbler, Golden Gate Park. San Francisco. You can just make out its chestnut rump below the wingtips.

This bird isn't typically around here, with this about the 10th record for the city. Ordinarily, they fly from their breeding grounds (southern Nevada down to Sonora, Mexico) to winter on the Pacific slope of Mexico, but some head NW instead of SE.
