The Grasshopper Sparrow is an inconspicuous grassland sparrow with a short tail and a proportionally large, flat head. It has a plain face, with a white eye-ring and a white stripe through the middle of its crown. Its back is intricately patterned with gray and chestnut, a color combination that is unique among sparrows. It has an entirely clear, buff-colored breast, with no streaks or spot. Juveniles are streaked overall until they reach adult plumage at the end of their first summer.
