Henslow's sparrow (Centronyx henslowii) is a North American passerine bird in the family Passerellidae. It was named by John James Audubon in honor of John Stevens Henslow. It was originally classified in the genus Emberiza and called Henslow's bunting.
Adults have streaked brown upperparts with a light brown breast with streaks, a white belly and a white throat. They have a pale stripe on the crown with a dark stripe on each side, an olive face and neck, rust-coloured wings and a short dark forked tail.
Measurements: Length: 4.3–5.1 in (11–13 cm) Weight: 0.4–0.5 oz (11–14 g) Wingspan: 6.3–7.9 in (16–20 cm) Henslow's sparrows breed in fields and meadows across interior eastern North America. Their range stretches from New York and Pennsylvania across the midwest to as far west as Kansas, with a disjunct population in North Carolina, though their populations are scattered and low-density. Historically, Henslow's sparrows were much more widespread and bred as far east as New England. They winter in weedy fields in the American south from Texas and Arkansas east to South Carolina, Georgia, and Florida.

GBIF citizen-science records
It is estimated from how often the Henslow's Sparrow is recorded against all the birds logged in Chicago (47 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
