Comments: NON-BREEDING: tidal mudflats and beaches; migrant flocks may pause in open areas such as antenna fields and airstrips (AOU 1983, Pratt et al. 1987). BREEDING: Swampy or mossy tundra, especially with scattered willow scrub (AOU 1983).
Habitat and Ecology
Non-Migrant: No. All populations of this species make significant seasonal migrations.
Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).
Locally Migrant: Yes. At least some populations of this species make annual migrations of over 200 km.
Comments: Total population estimated to be 471,000 (Morrison et al. 2001). Listed as "by far the most common stint" on Asian and Australian wintering grounds by Paulson (1993). A few dozen breed in Alaska (Morrison et al. 2001).

Red List Criteria
These birds are among the smallest of waders, very similar to the little stint, Calidris minuta, with which they were once considered conspecific. The red-necked stint's small size, fine dark bill, dark legs and quicker movements distinguish this species from all waders except the other dark-legged stints. It measures 13–17 cm (5.1–6.7 in) in length, 28–37 cm (11–15 in) in wingspan and 21–51 g (0.74–1.80 oz) in body mass. It can be distinguished from the western sandpiper and the semipalmated sandpiper in all plumages by its combination of a fine bill tip, unwebbed toes, and longer primary projection.
The breeding adult has an unstreaked orange breast, bordered with dark markings below, and a white V on its back. In winter plumage identification is difficult, although it is shorter legged and longer winged than the little stint. Juveniles have more contrasting mantle plumage and weaker white lines down the back than their relative. The call is a hoarse "stit".
Distribution and habitat
Red-necked stints are strongly migratory, breeding along the Arctic littoral of eastern Eurasia and spending the non-breeding season in South East Asia and Australasia as far south as Tasmania and New Zealand. They are rare vagrants to western Europe. They are often seen in western Alaska and occasionally elsewhere in the Americas.
Red-necked stints are highly gregarious, and will form flocks with other small Calidris waders, such as sharp-tailed sandpipers and curlew sandpipers in their non-breeding areas. See it here with curlew sandpiper.
Their breeding habitat is tundra. They nest on the ground and breed from spring to summer.
They forage in wet grassland and soft mud, mainly picking up food by sight. In their non-breeding habitat they feed on intertidal mudflats and along the muddy margins of freshwater lakes. They mainly eat insects and other small invertebrates.
