With breeding grounds high in the Siberian Arctic and a winter range extending as far south as New Zealand, Sharp-tailed Sandpiper Calidris acuminata is a champion long-distance migrant. In China migrates mainly along coast but regularly recorded inland. Common passage migrant Shanghai. HABITAT & BEHAVIOR Migrants often in marshy areas with vegetation as well as on intertidal mudflats. Juveniles strictly on coasts. ID & COMPARISON Breeding shows distinct rufous crown streaked black, a white eyebrow that often flares at the end and that is streaked black or brown, chestnut ear coverts, dark lores, and a thin white eye-ring. Upperparts black or brown with rufous and dull white fringing to feathers. Bold black spotting or streaking on neck and breast turning into chevrons on otherwise white lower breast, flanks, and undertail coverts. Breast has buff wash that is less clearly demarcated than Pectoral Sandpiper C. melanotos. Juveniles have blackish feather centers above, with rusty fringes (more buff on wing coverts), giving scaly appearance. White lines along mantle and scapulars usually prominent (but less so than Pectoral). Head pattern of Pectoral less contrasting; supercilium of Sharp-tailed cleaner (especially behind eye) and chestnut crown more prominent. Juvenile Sharp-tailed is bright and has prominent orange breast and breast streaking limited to a narrow band on upper breast; rest of underparts white. Winter adult a toned-down, greyish version of summer adult; distinct rufous cap present, but duller, with streaking usually restricted to sides of breast. In flight shows typical calidrid pattern of narrow white wing bar and white uppertail coverts divided by black central band from rump to tail. Streaking on white sides of rump make rump look darker than Pectoral. Juvenile Long-toed Stint C. subminuta appreciably smaller than Sharp-tailed. Male larger than female. BARE PARTS Bill short, slightly curved, black, with pale base to mandible; feet greenish-yellow. Legs shorter and posture usually more horizontal than Pectoral. VOICE Shrill, continuous twittering. Also soft, repeated plipp. — Craig Brelsford
