Spotted redshank 
(Choắt chân đỏ, Tringa erythropus)

Spotted Redshank (Choắt chân đỏ, Tringa erythropus) is a wader (shorebird) in the large bird family Scolopacidae.

The bird breeds in northern Scandinavia, the northern Palearctic, and migrates south to the Mediterranean, the southern British Isles, France, tropical Africa, and tropical Asia for the winter.

The term Charadriiformes comes from New Latin, combining the Greek word kharadrios ("a bird of river valleys" or "a bird of ravines") and the Latin suffix -formes meaning "forms" or "shaped like". Therefore, Charadriiformes translates to "birds shaped like or resembling the charadrius," which is a type of plover or stone curlew historically found in dry river beds or ravines. 

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 name Tringa is the Neo-Latin name given to the green sandpiper based on Ancient Greek trungas, a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle.

The specific erythropus is from Ancient Greek eruthros, "red", and pous, "foot".
