Chinese Name: 尖尾滨鹬

Range:
Breeds in northeast Siberia; winters south to New Guinea, the Pacific Islands, and eastern Australia.

Taxonomy:
Monotypic.

Size: 17-21 cm

Identification:
A medium-sized sandpiper similar to the equally-rare Pectoral Sandpiper, recalls Long-toed Stint but ~50% larger. 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
