Green sandpiper (Choắt bụng trắng, Tringa ochropus)

The green sandpiper (Tringa ochropus) is a small wader (shorebird) of the Old World.

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 ochropus is from Ancient Greek okhros, "ochre", and pous, "foot".
