The saltmarsh sparrow also has a slightly longer beak than the Nelson's sparrow. The inland subspecies of the Nelson's sparrow can be differentiated by its fainter streaking and brighter orange breast and sides, while the coastal subspecies of the Nelson's sparrow can be differentiated by its paler, less-contrasting plumage. ĭistinguishing this species from closely related sparrows such as the Nelson's sparrow can be difficult.
The tail feathers are short and sharply pointed. The face is orange with gray cheeks, a gray median crown stripe, brown lateral crown stripes, and a brown eyeline. Adults have brownish upperparts with a gray nape, white throat and belly, and pale orange breast and sides with brown streaking.
