River lapwing (Te cựa, Vanellus duvaucelii)
The river lapwing (Vanellus duvaucelii) is a lapwing species which breeds from the Indian subcontinent eastwards to Southeast Asia.
Its range includes much of northern and northeastern India, and extends through Southeast Asia to Vietnam.
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”).
