The long-toed sandpiper ( Calidris subminuta ) is a species from the family of snipe birds . The IUCN classifies the long-toed sandpiper as LC IUCN 3 1st svg(= least concern - not endangered). The population is estimated by the IUCN at 25,000 sexually mature individuals.

Appearance

The long-toed sandpiper reaches a body length of 13 to 14 centimeters. The wingspan is 33 to 35 centimeters. The weight varies between 25 and 35 grams.

The long-toed sandpiper bears a great resemblance to the meadow sandpiper in its splendid and simple dress , although it is somewhat longer-necked than this species. In its splendid dress, long-toed sandpipers have a maroon crown of the head that is dark brown and white striped. The cheeks are pale chestnut colored. The chest is pale yellowish brown with thin lines. The coat is dark brown to black. The feathers on the back are lined with dark chestnut to pale yellow, which makes the dorsal plumage appear clearly scaled. In the plain dress, the head and top of the body of adult birds are brown-gray. The underside of the body is white, with the breast striped brown-gray. The beak is black and pointed slightly downwards at the tip of the beak. The iris is dark brown. The feet and legs are yellow-greenish.

The distribution areas of the sandpiper and the sandpiper do not overlap because the sandpiper is a nearctic species. In the distribution area it can be confused with the pygmy sandpiper and the red throat sandpiper , differs from these species by its yellow-greenish legs.

Distribution area

The long-toed sandpiper is an exclusively Palearctic species. It breeds in Siberia east of the Ob, in the region around Magadan , in the south of the Chukchi peninsula , in the north of the Kamchatka and on the commanders' islands. Long-toed sandpipers prefer the mountain tundra as a habitat , but they are also found in marshland.

Long-toed sandpipers are migratory birds and migrate to southeast Asia, Indonesia and Australia in the winter months. In the wintering areas, the long-toed sandpiper is often associated with the Temminck sandpiper and the red throat sandpiper. Hibernating birds are often seen in inland swamps, but also occasionally in alluvial land on the coast and between sand dunes.

Way of life

Long-toed sandpiper

The long-toed sandpiper only eats invertebrates that it pecks from plants. It is mostly sociable and regularly nests in colonies. The nest is a shallow hollow between vegetation near the water. The clutch consists of two to four eggs. These have a gray-green basic color and are spotted brown. The breeding season is 18 to 22 days. Both parent birds are involved in the brood. The young birds are usually led by the male. The females leave the breeding ground after the chicks hatch. The juveniles fledge after 17 to 22 days and are independent shortly thereafter. They become sexually mature at the age of one year.
