Males (and, less frequently, females) perform aerial displays before mating. They also feed on seeds, berries, roots, nuts, and shoots. During the breeding season, they nest in the Arctic tundra, usually near ponds or on rocky ridges. The nest is placed on the ground in an exposed location with little or no vegetation, often at a pre-existing depression. This is the source of the specific name, alba, which is the Latin for "white". However, surveys suggest that Sanderling populations are declining, sharply in places. The northward migration begins in March at the southern end of their winter distribution. Sanderlings breed in the tundra of High Arctic Canadian islands and peninsulas, and rarely in Alaska. Their bills can penetrate only 2 or 3 cm (0.79 or 1.18 in) and as the water swirls around and retreats, the sand is softer; this makes it easier for the birds' beaks to penetrate further. It is highly gregarious in winter, sometimes forming large flocks on coastal mudflats or sandy beaches. [10], At breeding time sanderlings are territorial, with the male aggressively defending its territory. It measures about 3 inches across and 2.5 inches deep. When the tide is out, these crustaceans live in burrows some way beneath the surface.

The sanderling breeds in the High Arctic areas of North America, Europe and Asia. They are omnivores, which means that they eat both plants and animals. Because they are so widespread, it is not unusual for a Sanderling to become injured in some way. The sanderling is a small plump sandpiper, 18–20 cm (7.1–7.9 in) in length. In some areas, notably Chesapeake Bay where there has been a large fishery for horseshoe crab eggs, humans compete with Sanderlings and other shorebirds for food. Sanderling breeding range. Back to top, Although Sanderlings are one of our most common shorebirds, their populations are declining and they are listed as a species of high concern by the Western Hemisphere Shorebird Reserve Network. In North America, this diet largely consists of the isopods Excirolana linguifrons, Excirolana kincaidii, and the mole crab, Emerita analoga. For such common birds, most people know very little about them. If one spots a predator, it alerts the rest of the flock and all the birds quickly take off into the air. No, these birds do not make good pets. Sanderlings breed in the Arctic, visiting the UK in the winter and passing through on migration during spring and autumn. A., P. A. Smith, R. I. G. Morrison, C. L. Gratto-Trevor, S. C. Brown, and C. A. Friis (2012). In the northern winter, it has a nearly cosmopolitan distribution across the world's marine coasts. And all dishes are prepared a la cocina fresca (in the fresh kitchen method), with freshly made sauces, homemade corn tortillas, and fresh local seafood and produce prepared daily. Conservation of long-distance migrants like Sanderlings is always complicated because of the birds’ reliance on distantly separated staging areas, which have to provide enough food at the right time, and which are all subject to their own habitat pressures. Studies in Canada have found that females sometimes mate with multiple males in sequence when conditions are favorable. They roost on beaches in closely packed flocks of up to several thousand birds, standing or squatting against the wind and jostling for the least exposed positions in the flock. Like many shorebirds and sandpipers, Sanderlings live in different types of habitats when they are breeding and when they are vacationing for the winter. On the nesting grounds males establish territories about 400 yards across, and both members of a breeding pair chase intruders from the territory. Declines are probably caused by development or alteration of shoreline habitats—the sandy beaches Sanderlings live on are also prized by humans for recreation.

They use a variety of foraging techniques, but the most common techniques are picking food from the ground or water, or probing into wet sand or mud. It shows a strong white wingbar in flight, and runs along the sandy beaches it prefers with a characteristic "bicycling" action of its legs, stopping frequently to pick small food items. Others breed with multiple partners, and males will breed with multiple females, or females with multiple males. They don’t migrate in specific patterns, and multiple populations mix while migrating. Back to top. In that time, peak migration counts in Massachusetts dropped from 10,000-30,000 birds in the 1950s to an average of just 2,000 birds. North American Bird Conservation Initiative. During migration and winter Sanderlings may flock with other small shorebirds such as Dunlins, Red Knots, Black-bellied Plovers, Willets, Short-billed Dowitchers, Long-billed Dowitchers, Ruddy Turnstones, Semipalmated Sandpipers, and Western Sandpipers. As breeding season approaches, flocks begin to converge and migrate north to their breeding grounds. On the nesting grounds, these birds mainly eat insects and some plant material.

Nest predators include Parasitic Jaegers, Long-tailed Jaegers, Glaucous Gulls, Snowy Owls, artic foxes, and wolves. It is a complete migrant, travelling between 3,000 to 10,000 km (1,900 to 6,200 mi) from its breeding grounds to its wintering sites. The species typically chooses nesting sites on dry stony areas near wet areas, from 60 m (200 ft) above sea level to 800 m (2,600 ft). Alfred A. Knopf, New York, NY, USA. (2019). Willapa Bay, near Tokeland, Washington. When the tide comes in, they move into the upper layers of sand and feed on the plankton and detritusthat washes over them with each wave.
