Red-necked stint (Rẽ cổ hung, Calidris ruficollis) 

The red-necked stint (Calidris ruficollis) is a small migratory wader that breeds in northeast Russia and spends the non-breeding season along the coastlines of Southeast Asia and Australasia.

Charadriidae, Charadrius: Late Latin word for a yellowish bird mentioned in the fourth-century Vulgate; from Ancient Greek kharadrios a bird found in ravines and river valleys (kharadra, "ravine").

The word Scolopacidae is New Latin, derived from the genus name Scolopax (Latin for "snipe" or "woodcock") and the common zoological suffix for family names, -idae.

The genus name Calidris is from Ancient Greek kalidris or skalidris, a term used by Aristotle for some grey-coloured waterside birds.

The specific ruficollis is from Latin rufus, "red" and collum, "neck".
