Sharp-tailed sandpiper 
(Rẽ đuôi nhọn, Calidris acuminata)

The sharp-tailed sandpiper (Calidris acuminata) is a small-medium migratory wader or shorebird, found mostly in Siberia during the summer breeding period (June to August) and Australia for wintering (September to March).

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 acuminata is from Latin acuminatus, 'sharp, pointed'.
