Crescent sandpiper

The common sandpiper ( Calidris ferruginea ) is a species of bird from the family of snipe birds (Scolopacidae). It is a breeding bird of the tundras of Siberia. In Central Europe it is a regular migrant, especially during the autumn migration . Between 500 and 6,000 individuals are observed annually in the Wadden Sea in the Netherlands. In very rare cases sickle sandpipers also spend the summer on the Central European coast.

description

The crescent sandpiper grows to almost 20 cm, about the size of a star , and has a wingspan of around 35 cm. It weighs 40 to 60 g and can live up to 17 years (oldest, recaptured individual). The name comes from its long and clearly curved beak . However, the beak is not a clear identification feature, as large differences in length and curvature can occur. In plumage easily by Alps beach rotor to be confused, however, long-legged, slightly lighter in color and quiet in motion. In breeding plumage easy to identify on the deep rust-red breast and curved beak. The dunlin's legs are colored black in every dress. Males and females are colored the same. His call sounds like “djürri” or “dirrit”. Here, too, there is a risk of confusion with the dunlin, which, however, sounds deeper and harder. During courtship and breeding in the breeding areas, singing with multi-part stanzas also occurs.

distribution and habitat

The common sandpiper is a breeding bird of the north of Russia. It breeds there from the Taimyr Peninsula to the Chukchi Peninsula . The New Siberian Islands may also be part of its breeding area. It occurs both in the dry and in the wet steppe. A large population moves from central Siberia across continental Europe and the Mediterranean to West Africa in the wintering areas, which enables the observation of crescent sandpipers in Germany on a regular basis.

Sickle sandpipers are mainly to be found in the coastal, arctic tundra areas as breeding birds . It also likes to breed on river banks, also inland. During the migration period , crescent sandpipers can be found on pure silty areas on the coasts, but also less often, but across the board, inland. Small areas are often sufficient for the birds to search for food.

food

Bristle worms , small mussels and snails as well as insects and their larvae are among his preferred, purely animal dishes. Flies and mosquitoes serve as food at the breeding site.

At rest areas in winter, the sickle sandpiper spends eighty percent of its time looking for food. In its breeding area, however, it spends 55 to 65 percent of the daylight hours looking for food. Sickle sandpipers move more slowly and calmly than dunlins . He is also more specialized in probing and very often goes up to his stomach in the water.

Reproduction

Calidris ferruginea

Sexual maturity is reached from the 3rd year of life. Couples look for and usually find each other in the wintering areas. During the breeding season between mid-May and late June, the female lays up to five eggs . The first Juvenile , however, no earlier than mid to late July fledge .
