Similar species:

The Baird's sparrow is similar in shape to the grasshopper sparrow but
has streaks across the breast. Juvenile grasshopper sparrows have streak-

ed breasts and can be separated by their whitish, not yellow, crown

stripe and lack of dark streaks on the side of the throat. Henslow's spar-

row has olive face and rusty wings. LeConte's sparrow has different face

pattern. Other sparrows likely to be found in field habitats have longer

tails and smaller heads as well as different markings (song, vesper, Savan-

nah, field, for example).
