The Terek sandpiper (Xenus cinereus) is a small

Terek River which flows into the west of the Caspian Sea
, as it was first observed around this area.

Taxonomy

The Terek sandpiper was

monotypic, no subspecies are recognised.[4]

Among the

Turgai Sea dried up, which happened just around this time.[6][7][8]

Description

Slightly larger than the common sandpiper at 22–25 cm (8.7–9.8 in) length, its long upcurved bill – somewhat reminiscent of an avocet's, but not as strongly curved – makes it very distinctive. As the scientific specific name implies, this wader has a grey back, face and breast in all plumages; a white supercilium may appear more or less distinct. The belly is whitish and the feet yellow; the bill has a yellowish base, with the rest being black.

The call is a high whistle.

Distribution and ecology

This bird breeds near water in the

Neotropics, where they arrive either as migrating birds from Africa, or as North American strays accompanying local waders south for winter. Such vagrants have been recorded as far south as Argentina.[9][10][11]

The overall genetic variation in Terek sandpipers across their range is low, with some evidence of contractions followed by expansion. Although the geographically isolated Dniephe River population in Eastern Europe does show significant genetic differentiation.[12]

It feeds in a distinctive and very active way, chasing insects and other mobile prey, and sometimes then running to the water's edge to wash its catch.

It lays three or four eggs in a lined ground scrape.

The Terek sandpiper likes to associate with

Rio de Janeiro state) was noted to pair up with a spotted sandpiper (Actitis macularius).[11]

This is one of the species to which the Agreement on the Conservation of African-Eurasian Migratory Waterbirds (
