Dunlin is an abundant bird species that nests around Arctic regions of the world. Dunlin, (Calidris alpina), also known as the Red-backed Sandpiper, is one of the most common and creative birds in the Sandpiper Group. Dunlin is a family member of the scolopacidae (order Charadrioformes). It is about 20 centimeters (8 inches) long and has a bill bent at the bottom of the leg. This article will be discussing in depth on Dunlin Bird and its nesting, behavior and facts.

Dunlin bird is a small migratory wader that exhibits great variability in body and bill size and distribution and is easily confused with many other birds. Dunlin bird is a small, sterling-sized, with a small, slightly lower-curved, bill with ad summer plumage upper parts brown, with a closed breast and black belly.
Dunlin (Calidris alpina) is a small wader that sometimes falls apart with other “stints” of Irolia. The English name is a dialect form of “Dunlings”, first recorded in 1515-22. It is derived from the right, “dull brown”, with the suffix, meaning any person or thing of a given quality. The name of the clan is the ancient Greek kalidiris or scalidris, a term used by Aristotle for some gray-colored aquatic birds. The specific alpina is from the Latin language and means “high mountains”, in this case referring to the Alps.
It is a circopolar breeder in the aortic or subcortical region. The birds that breed in Northern Europe and Asia migrate long distances in winter in South Africa, Southeast Asia and the Middle East. Birds that breed Alaska and the Canadian Arctic migrate to the Pacific and Atlantic coasts of North America at a very short distance, although they nest over Asia's northern Alaska overwinter. There are many Dunlin winters on the Iberian southern coast.
An adult Dunlin shows a distinctive black belly in the breeding plumage that no other similarly sized wader has. Winter Dunlin bird is basically gray and white at the bottom. The teens are brown on top with two white “V” shapes on the back. They usually have black marks on the flanks or abdomen and show a strong white wing on the aircraft.
The legs and slightly fingered bill are black. Different subspecies differ mainly in the extent of reproductive plumage and bill length rufus coloration. The length of the bill varies between genders, wives have more bills than men.
There is a shallow scrap on the land lined with nesting plants, in which four eggs are usually laid and are hatched by male and female parents. Roofs are precocious but are found during early development. They started flying at about three weeks of age. Most of the brood care is provided by the male, as the female brood deserts and often leaves the reproductive zone.
The call is a typical sandpiper “peep,” and a strenuous trail of display songs.
Dunlin is one of the species where the agreement regarding conservation of African-Eurasian migration waterbirds (AW) applies.
Specific hybrids have been found between this species and the white-crushed sandpiper, as well as the purple sandpaper, from the Atlantic coast of North America and Europe, respectively.
During the winter, Dunlin bird is extremely lush green, sometimes making large swings in coastal mudflats or sandy beaches. A large number of adjacent flights are seen during stop-overs during migration or at their winter residence.
This bird is one of the most common warders in its breeding and winter ranges and has a tendency to compare with other species. At 17-25 cm (6.7-8.3 in) in length and with wingspan of 32-36 cm (13 in14 in), it is more like a normal sterling with size, but more like a dense bill with a stater.
Dunlin is moved to the coastal mudflats with beaches it likes a featured “sewing machine” feeding action, systematically picking up small food items. Insects form the major part of the Dunlin diet in the nest; It eats mollusks, worms and crustaceans in coastal areas.
Dunlin is an expatriate fighter, though they return to their birth patches with the people of Sweden and Finland's southern Dunlin (Calidris alpina Schinzie) or show very strong filopatry in the vicinity. Habitat fragmentation reduced the availability of these bird habitat patches by reducing the size of the patch and increasing the patch isolation. This connection between patches is reduced as the movements of Dunlin are reduced which makes them more susceptible to descent in these places. Future management of southern Dunlin conservation should include increasing connectivity between habitat patches.
The breeder has a grayish brown hood and a brown hood. Dunlin was once called a red-back sandpiper, with flashes, bright rust backs, and black belly patches at the end of its breeding. It is now named for its non-reproductive plumage, which is a light gray-brown or “dune” color. Dunlin is an abundant species that nests around the world's Arctic birds.
At the breeding ground, insects and insect larvae are the most important sources of food. In coastal habitats, Dunlin also eats marine worms, small crustaceans, mollusks and other aquatic animals. They sometimes eat seeds and leaves.
Along the coast are found small small waders. Its breeding plumage has some down-curved bills and a distinct black belly patch.
