Red-necked Stint
Encyclopedia
The Red-necked Stint is a small migratory wader
.
, 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 (11–14.6 in) in wingspan and 21–51 g (0.740753204207351–1.8 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".

Western Sandpiper
The Western Sandpiper, Calidris or Erolia mauri, is a small shorebird.Adults have dark legs and a short thin dark bill, thinner at the tip. The body is brown on top and white underneath. They are reddish-brown on the crown. This bird can be difficult to distinguish from other similar tiny...

Semipalmated Sandpiper
The Semipalmated Sandpiper, Calidris pusilla, is a very small shorebird. It is sometimes separated with other "stints" in Erolia but although these apparently form a monophyletic group, the present species' old genus Ereunetes had been proposed before Erolia.Adults have black legs and a short stout...

Distribution and habitat
Red-necked Stints are strongly migratoryBird migration
Bird migration is the regular seasonal journey undertaken by many species of birds. Bird movements include those made in response to changes in food availability, habitat or weather. Sometimes, journeys are not termed "true migration" because they are irregular or in only one direction...

Breeding
Their breeding habitat is tundraTundra
In physical geography, tundra is a biome where the tree growth is hindered by low temperatures and short growing seasons. The term tundra comes through Russian тундра from the Kildin Sami word tūndâr "uplands," "treeless mountain tract." There are three types of tundra: Arctic tundra, alpine...

Diet
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.Further reading
