Great knot (Rẽ lớn ngực đốm, Calidris tenuirostris)

The great knot (Calidris tenuirostris) is a small wader in the genus Calidris of the family Scolopacidae. 
This bird species is migratory; it breeds in eastern Siberia, Russia, and flies to southern Asia and Australia in the winter in northern hemisphere.

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 tenuirostris is from Latin tenuis "slender" and rostrum "bill".
