Long-toed Stint Calidris subminuta is a common migrant along the Chinese coast. Regularly recorded inland. Winter records from Guangxi, Guangdong, and Hainan; also Taiwan. HABITAT & BEHAVIOR Migrants prefer freshwater and brackish coastal habitats with vegetation but can occasionally be found on mudflats. Usually seen singly or in small groups. ID & COMPARISON Small, but slightly larger than very similar Least Sandpiper C. minutilla; more slender and longer-necked than Least, with longer legs and toes. Both species have long tertials covering wing tip, and hence show no primary projection. Least Sandpiper is slightly smaller and less bright and has a fainter white eyebrow that does not split; eyebrow of Least reaches bill and forehead, isolating the dark lores, but in Long-toed dark forehead meets lores at base of bill, and hence supercilium does not reach base of bill. Juvenile and non-breeding Long-toed resemble miniature Sharp-tailed Sandpiper C. acuminata. Breeding adults have black-streaked, rufous crown that extends to base of bill. Very narrow black lores. White supercilium, often split over eye, extends between lores and crown. Face, neck, and breast streaked brown or black. Mantle, scapulars, coverts, and tertials mainly black with rufous fringes and white tips (prominent white “mantle-V” in juveniles). Underparts in all plumages white. Non-breeding adult grey above, with dark-centered feathers fringed greyish-brown. Juvenile similar to adult, but brighter; has dark ear patch. Long legs yellow or green; in flight, toes trail behind tail; narrow white wing bar and white uppertail coverts divided by black central band from rump to tail. BARE PARTS Bill black, with pale base to mandible. VOICE Soft, liquid flight call. — Craig Brelsford
