What is a sandpiper?
A sandpiper is any shorebird in the family Scolopacidae, also including woodcocks and snipes. They are small to medium-sized, ranging from 15 to 30 cm (6 to 12 inches) in length. Sandpipers are often seen in large groups on sea beaches and inland mud flats during migration.
Sandpipers possess moderately long bills and legs, narrow wings, and short tails. Their coloring is usually a mix of brown, buff, and black on top, with white or cream underneath. They forage for insects, crustaceans, and worms on beaches and mud flats, making thin, piping sounds as they run along the sand. Many sandpipers nest in the Arctic and sub-Arctic, migrating through the North Temperate Zone to their breeding sites.

Where do sandpipers usually live?
Sandpipers live on ocean coastlines and inland waters, feeding on beaches and mud flats. They are often found in large flocks during migration in the North Temperate Zone on their way to breeding sites.
Many sandpipers nest in Arctic and sub-Arctic regions. The common sandpiper breeds on grassy shores of lakes and rivers throughout Eurasia and winters from Africa to Australia and Polynesia. The spotted sandpiper breeds beside streams and ponds of sub-Arctic and temperate North America and winters as far south as Argentina. Sanderlings nest on barrens near the sea around the North Pole and winter on sandy beaches virtually everywhere.

What do sandpipers eat?
Sandpipers are shorebirds that belong to the family Scolopacidae. They feed on ocean coastlines and inland waters, picking up insects, crustaceans, and worms from beaches and mud flats. They use their slender bills like forceps to pick up surface invertebrates or probe in the mud.
The upland sandpiper also eats grasshoppers and other insects. Seedsnipe are unique within the order because they eat primarily vegetable matter, such as seeds, buds, shoots, and leaves.

How can you identify a sandpiper by its appearance?
Sandpipers are shorebirds, generally small to middle-sized, ranging from about 15 to 30 cm in length. They typically have moderately long bills and legs, along with long, narrow wings and fairly short tails.
Their coloring often features a complex pattern of browns, buffs, and blacks on their upperparts, creating a "dead-grass" camouflage, with white or cream coloring on their underparts. They tend to appear paler in autumn compared to spring. While some sandpiper species have unique identifying marks such as speckled breasts, white rump bands, or distinctive throat patches, their overall appearance is quite similar, making them difficult to differentiate. The spotted sandpiper, for example, has black spots on its underparts during the summer.

How do sandpipers find their food along the shore?
Sandpipers, members of the Scolopacidae family, are shorebirds that feed on beaches and mud flats. They run along the water's edge, using their slender bills like forceps to pick up insects, crustaceans, and worms on the surface or probe in the mud. Some species use their bills to probe crustacean burrows and worm burrows. They are known to make thin, piping cries while running or flying.

Why do some sandpipers migrate long distances every year?
Sandpipers, members of the Scolopacidae family, are shorebirds that often migrate long distances annually due to their high metabolic rate and need for abundant food sources. Many sandpipers nest in the Arctic and sub-Arctic regions and travel through the North Temperate Zone to reach their breeding sites.
Migration enables them to exploit fluctuating resources and settle in areas where survival would otherwise be impossible. They migrate from northern Arctic regions to tropical winter regions, taking advantage of productivity fluctuations in both life zones. During the summer, the Arctic has high vegetal and animal production, which many ducks and waders exploit. As winter approaches and food becomes scarce, these birds migrate to the tropics, where the rainy season has increased food production.

Sandpiper, any of numerous shorebirds belonging to the family Scolopacidae (order Charadriiformes), which also includes the woodcocks and the snipes. The name sandpiper refers particularly to several species of small to middle-sized birds, about 15 to 30 cm (6 to 12 inches) long, that throng sea beaches and inland mud flats during migration.
Sandpipers have moderately long bills and legs, long, narrow wings, and fairly short tails. Their colouring often consists of a complicated “dead-grass” pattern of browns, buffs, and blacks on the upperparts, with white or cream colouring below. They are frequently paler in autumn than in spring. Some species have distinguishing features, such as speckled breasts, white rump bands, or contrasting throat patches, but their general appearance is similar and they are notoriously difficult to identify. Most puzzling are the smallest sandpipers, known as peep, stint, or oxeyes. Most of these, formerly divided among the genera Erolia, Ereunetes, and Crocethia, are now placed in the broad genus Calidris.
Sandpipers feed on the beaches and mud flats of ocean coastlines and inland waters, running along near the water and picking up their food of insects, crustaceans, and worms. They utter thin, piping cries while in flight or while running along the sand. Sandpipers usually nest on the ground in the open, in a scantily lined little hollow. They lay four spotted eggs, from which hatch active, downy young. Many sandpipers nest in the Arctic and sub-Arctic regions and pass through the North Temperate Zone in great flocks on the way to their breeding sites.

The common sandpiper (Actitis, or sometimes Tringa, hypoleucos) is an abundant breeder on grassy shores of lakes and rivers throughout Eurasia, and it winters from Africa to Australia and Polynesia. This species is notable for a nervous mannerism of wagging its tail. The closely related spotted sandpiper (A. macularia) is the best-known New World sandpiper; this species breeds beside streams and ponds of sub-Arctic and temperate North America and winters as far south as Argentina.
The solitary sandpiper (Tringa solitaria), which breeds in North America and winters in South America, is unusual in nesting not on the ground but in the old tree nests of other birds. The closely related green sandpiper (T. ochropus) is its slightly larger counterpart in boreal and mountainous regions of Eurasia.
The genus Calidris contains many birds known as sandpipers, along with others such as the knot and the sanderling and the dunlin—which is sometimes called the red-backed sandpiper. The least sandpiper (C. minutilla), less than 15 cm in length, is the smallest sandpiper. It is sometimes called the American stint and is abundant in Alaska and across sub-Arctic Canada to Nova Scotia. It winters on coasts from Oregon and North Carolina to South America. The purple sandpiper (C. maritima) breeds in foggy Arctic highlands, chiefly in eastern North America and northern Europe, and winters as far north as Greenland and Great Britain. It is grayish with yellow legs and bill and is easily approached in the field. Another Old World species is the rufous-necked sandpiper (C. ruficollis), which breeds in Siberia and winters as far south as New Zealand and Tasmania. The white-rumped sandpiper (C. fuscicollis), which breeds in Arctic North America and winters in southern South America, is rust-coloured in breeding season but gray otherwise. The upland sandpiper (Bartramia longicauda), also called Bartram’s sandpiper and, mistakenly, the upland plover, is an American bird of open fields. It is a slender, gray-streaked bird almost 30 cm long that feeds on grasshoppers and other insects.
