Terek sandpiper (Xenus cinereus)

The Terek sandpiper (Xenus cinereus) is a small migratory Palearctic wader species, the only member of the genus Xenus.

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.

Not very common but ocasionaly  we can see near the Black Sea litoral.
