Small peep, very like a western sandpiper. Short, straight, thin bill. Some observers r saw split supercilium. Some observers saw a lack of palmation. Dark tertials really stood out. Continuing rarity. M. U. Evans: Small sandpiper, between Western and Least Sandpiper in size; mantle light gray-brown but some feathers showing darker centers, giving a somewhat mottled appearance. Bill appears shorter and more pointed than nearby Western Sandpipers. Wings show sharp-angled, dark brown pattern along scapulars, with lesser primary coverts showing contrasting dark leading edge of folded wing. Away from shoulder area, lesser coverts are mid-gray with dark tips and narrow light margins. Primaries are dark gray to black and project past the tail; the apparent white outer tail covert feathers barely show below the dark tertials. In-field observations augmented by inspection of enlarged photographs taken with 500mm lens on full-frame digital camera. Only one individual detected by Evans.
