Chipping Sparrow look-alikes

Key differences

The American Tree Sparrow has a bicolored bill (dark upper, yellow lower mandible), a single dark spot on its unstreaked breast, and a gray head with a rusty eye-line (no white supercilium). It also has rusty wing bars. Chipping Sparrows have a dark bill (in breeding season), no breast spot, a white supercilium, and a black eye-line.

Key differences

The Field Sparrow has a pink bill, a plain gray face with a rusty crown (but no distinct black eye-line or white supercilium), and a plain gray breast. Its song is a slurred series of whistles that accelerate into a trill, distinct from the Chipping Sparrow's dry trill.

Key differences

The Clay-colored Sparrow is paler overall, with a buffy-brown face, a distinct dark malar stripe, and a pale median crown stripe. It lacks the bright rusty cap and prominent white supercilium of the Chipping Sparrow. Its song is a series of buzzy 'bzzzt' notes.

Key differences

House Sparrows are stockier, with a much thicker bill. Males have a gray crown, chestnut nape, black bib, and white cheeks. Females are duller brown with a plain buffy supercilium. Chipping Sparrows are more slender, have a rusty cap, and a distinct white supercilium and black eye-line.
