1/ Long-billed plover (Choi choi lớn, Charadrius placidus)

2/ Little ringed plover (Choi choi nhỏ, Charadrius dubius) 
The specific dubius is Latin for doubtful, since Sonnerat, writing in 1776, thought this bird might be just a variant of common ringed plover.

Pluvialis is a genus of plovers, a group of wading birds comprising four species that breed in the temperate or Arctic Northern Hemisphere.
The genus name is Latin and means relating to rain, from pluvia, "rain". It was believed the birds flocked when rain was imminent.

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 family name Charadriidae has the same origin as the order name from the Greek word kharadrios ("a bird of river valleys" or "a bird of ravines").

Vanellus is a Latin word meaning "little fan". The name refers to the sound of the wings in flight, which was compared to the sound of a winnowing fan. It is a diminutive of the Latin word vannus (“fan for winnowing grain”).
