In Eurasia, it breeds in Spitsbergen and areas of northern Russia from the Taymyr Peninsula to the New Siberian Islands. Wader Study Group Bulletin 119:178–194. Because of this, human interaction does not impact them severely, and the IUCN lists them as Least Concern. Sanderlings are also vulnerable to pollution from pesticides and, especially, oil spills due to their close association with the ocean edge. The northward migration begins in March at the southern end of their winter distribution. Its behavior is also distinctive. CTRL + SPACE for auto-complete. (2002). Studies in Canada have found that females sometimes mate with multiple males in sequence when conditions are favorable. Lutmerding, J. Well-developed and downy, with dark legs and bill and black eyes. Andres, B. During the spring and summer, these birds fly north … all the way north! During the winter and its migration, it is most commonly found on coastal sandy beaches, but also occurs on tidal sand flats, mud flats and the shores of lakes and rivers. Many of those kept in zoos share their enclosure with several other shorebird species. On the nesting grounds males establish territories about 400 yards across, and both members of a breeding pair chase intruders from the territory. Willapa Bay, near Tokeland, Washington. 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 are wild birds, and do not like interacting with humans. On the nesting grounds, these birds mainly eat insects and some plant material. Their backs and heads are tan or brown and mottled with darker colors, while their underbellies are white or cream colored. Mostly sand crabs and other invertebrates. It can be told from other small wading birds, given good views, by its lack of a hind toe. Sanderlings are social birds, and usually congregate in flocks. When the tide is out, these crustaceans live in burrows some way beneath the surface. Sanderling is not on the 2014 State of the Birds Watch List. These little birds feed on a wide variety of small organisms. The nest is placed on the ground in an exposed location with little or no vegetation, often at a pre-existing depression. 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. The sanderling is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) applies. The juvenile bird is spangled black and white, and shows much more contrast than the adult. They live in virtually every ecosystem close to the ocean, even some a little ways inland. Less commonly, they may winter on mudflats, lakeshores, and riversides.Back to top, Sanderlings feed by running down the beach after a receding wave to pick up stranded invertebrates or probe for prey hidden in the wet sand. The birds appear to rush madly around at the edge of the surf, but in reality they are maximising their chances of catching as many prey animals as possible when they are at their most vulnerable near the surface. The sanderling breeds in the High Arctic areas of North America, Europe and Asia. The sanderling is a small plump sandpiper, 18–20 cm (7.1–7.9 in) in length. The sanderling is a small, plump, energetic wading bird. No, these birds do not make good pets. Sanderlings may also skim food from shallow pools while running, pick up moving prey on the ground, or—during the summertime—snap at flying insects. Explore Birds of the World to learn more.

Like many shorebirds and sandpipers, Sanderlings live in different types of habitats when they are breeding and when they are vacationing for the winter. Write CSS OR LESS and hit save. In spring, may feed heavily on eggs of horseshoe crab. (2019). In the spring, when much breeding activity is taking place in the benthic community, there may be as many as 4000 invertebrates per square metre, but their average size is smaller than later in the year. Both sexes incubate. In the northern winter, it has a nearly cosmopolitan distribution across the world's marine coasts. Wintering birds on southern coasts may eat corn chips and other junk food left by people. A flock displaying their distinctive behavior of running with the ebb and flow of waves (while feeding). Population estimates of North American shorebirds, 2012. On beaches, Sanderlings are strong, fast runners as they perpetually scurry just ahead of arriving and retreating waves. Its diet includes small crabs, amphipods and other small crustaceans, polychaete worms, mollusks, and horseshoe crab eggs. Sanderlings feed by running down the beach after a receding wave to pick up stranded invertebrates or probe for prey hidden in the wet sand. In the “off season,” these birds spend their winters on sandy beaches, lakesides, mud flats, estuaries, and tidepools. In most places, it is also illegal to capture, harm, harass, or kill a Sanderling. It is pale grey above and white underneath, and there is a black mark at its shoulder where the folded wing meets the body. Some individuals mate with the same partner for an entire season and both birds raise the young together. The bird alternately flutters and glides in an erratic path in an area about 200 yards wide, dipping low to the ground and rising to 30 feet high or more while vocalizing; these displays can last 2 minutes. Their enclosures usually contain a shallow water body, and a sandy beach for them to forage on. These birds are relatively light colored, with moderately long legs and beaks. Both their legs and their beaks are black. North American Bird Conservation Initiative. A. and A. S. Love. These widespread and common birds spend their time running along sandy beaches and sandbars in search of small prey. The nest is probably built by the female alone. 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. 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). When confronted with a predator, incubating parents freeze on the nest until the last second, when they creep away from the nest while feigning injury. 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. These interesting little birds have a number of different traits and behaviors that make them unique. 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. 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. Their backs and heads are tan or brown and mottled with darker colors, while their underbellies are white or cream colored. Many make dramatic, aerial display-flights during courtship. US Department of Interior, Washington, DC, USA. The sanderling consists of two subspecies: Sanderlings feed on invertebrate prey buried in the sand in the upper intertidal zone. Black border marks southern limit. The chicks follow their parents soon after hatching, and the parents protect them and show them how to find food. A more recent review (Thomas et al., 2004) indicates, however, that the sanderling is a fairly typical "stint" or small sandpiper and should be separated from the large knots with its closest relatives in a distinct genus. The specific alba is Latin for "white".[3]. Females usually lay about four eggs, and incubation lasts around three or four weeks. These little birds live along the coastline of virtually every landmass on earth. They spend the winter on sandy beaches all over the world; some stop as far north as southern Alaska, Nova Scotia, and Newfoundland while others go the length of South America. As breeding season approaches, flocks begin to converge and migrate north to their breeding grounds. According to Christmas Bird Counts, there was an overall decrease of 0.5% per year between 1959 and 1988, and California counts decreased by 3.7% per year. When the tide comes in, they move into the upper layers of sand and feed on the plankton and detritus that washes over them with each wave. During the breeding season, they nest in the Arctic tundra, usually near ponds or on rocky ridges. If one spots a predator, it alerts the rest of the flock and all the birds quickly take off into the air. Zookeepers feed these birds a variety of small fish, crabs, krill, shrimp, clams, crickets, mealworms, and more. For other uses, see, "The new species of birds in Vroeg's catalogue, 1764", "Birds in the sales catalogue of Adriaan Vroeg (1764) described by Pallas and Vosmaer", Sanderling Species text in The Atlas of Southern African Birds,, Creative Commons Attribution-ShareAlike License. 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. Once they are two weeks old the chicks begin learning to fly, and are usually independent within a week or so. In spring, birds migrating north from South America consume large numbers of horseshoe crab eggs in the Delaware Bay area. (2014). Dull green to olive-brown or greenish-blue), marked with brown spots and blackish streaks. Humans have not domesticated Sanderlings in any way. The name derives from Old English sand-yrðling, "sand-ploughman". 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. They feed by running along the edge of the water in search of prey, and probing their beaks into sands and soft soils. They are omnivores, which means that they eat both plants and animals. If its size is misjudged, a sanderling in breeding plumage can be mistaken for some varieties of stint, or a sanderling in winter plumage can be mistaken for a dunlin or red knot. Back to top. This bird is similar in size to a dunlin, but stouter, with a thick bill. In The Birds of North America (P. G. Rodewald, editor). [2] The genus name is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-coloured waterside birds.
