There are two adult plumage variations known as the tan-striped and white-striped forms. On the white-striped form the crown is black with a white central stripe. The supercilium is white as well. The auriculars are gray with the upper edge forming a black eye line.
On the tan form, the crown is dark brown with a tan central stripe. The supercilium is tan as well. The auriculars are gray/light brown with the upper edge forming a brown eye line. Both variations feature dark eyes, a white throat, yellow lores and gray bill. There is variation and some individuals may show dark lateral stripes of each side of the throat.
White-throated sparrows breed in central Canada and New England. They nest either on the ground under shrubs or low in trees in deciduous or mixed forest areas and lay three to five brown-marked blue or green-white eggs. In winter, it migrates to the southern and eastern United States.
