***very rare. Spizella showing traits of Chipping and Clay-colored. At the north end of the park on the west side, right here- https://maps.app.goo.gl/fQ5EaRQxmde697vT8?g_st=ic Initially thought Clay-colored, but then was confused by the apparent dark lores by the eyes. Seems to be HY; coverts all look fresh, and there is some slight flank streaking. The only photos in eBird and other sources are in Apr-Jul, so no good comparisons of basic-plumaged birds. Pro Clay-colored traits: Mostly pale lores Extensive black base of median crown stripes Buffy upper eye arc Central crown stripe whitish as base and then grayish posteriorly Whitish highlight in supercilium above eye Pro Chipping traits: Some darkness in lores next to eye Rusty highlights in posterior median crown stripes Almost no lower dark border to cheek Some traits are ambiguous. E.g. the buffy sides of the breast, whitish base to malar, and pale highlight in supercilium above and behind the eye are typical for Clay-colored, but this much variation expected in some immature Chipping. Edit 5/16/2025- adding some photos of a specimen from February 1933, which is in the Carnegie Museum of Natural History in Pittsburgh, PA. This specimen is cited here- https://sora.unm.edu/sites/default/files/journals/condor/v092n04/p1080-p1081.pdf. All specimen photos copyright Serina Brady/Carnegie Museum. The description of the specimen in the paper describes the nearly solid gray nape and brown uppertail coverts as supporting CCSP. It makes no mention of CHSP characters, though assumedly at least one is the dark lores. That said, Chipping can have a mostly gray nape, which often confuses birders. Additionally, the uppertail coverts are brown and the rump is gray, which is consistent with Chipping.
