Almost identical to [[Long-billed Dowitcher]]. Bill lengths overlap with females having longer bills than males. Distinguished in breeding plumage by whitish belly and spotted rather than barred sides of breast. Juveniles distinguished by heavily patterned upperparts, particularly tertials with internal markings. In winter plumage, not safely distinguished except by voice. Typical call a mellow whistled "tu-tu-tu." Long-billed is more vocal often keeping contact while feeding. Flight call a higher pitched squeaky "keeek" recalling Sanderling. | Almost identical to [[Long-billed Dowitcher]]. Bill lengths overlap with females having longer bills than males.
