From Long-toed Stint, told by size, at least slight rufous tones on crown in all plumages, significantly longer legs giving taller appearance, and thicker bill. From Pectoral Sandpiper, distinguished by presence of streaking on flanks (versus clean flanks in that species), less distinct white supercilium, more warm tones on crown, and in breeding plumage, chevron-shaped (as opposed to pure streaked) markings on underparts; Pectoral also almost always shows pale tones on bill-base while Sharp-tailed often has all-dark bill.

Similar looking species: Long-toed Stint, Pectoral Sandpiper

Habitat: Mudflats, sandflats, flooded grasslands, and brackish lagoons.

Behaviour/Ecology: Typically feeds at water’s edge on insects, snails, and crustaceans.
