Thalasseus, the crested terns, is a genus of eight species of terns in the family Laridae.
The generic name is derived from the Ancient Greek Thalassa meaning "sea".

1/ Greater crested tern (Nhàn mào, Thalasseus bergii), also called crested tern or swift tern
 The species epithet bergii commemorates Carl Heinrich Bergius, a Prussian pharmacist and botanist who collected the first specimens of this tern near Cape Town.

Buttonquail or hemipodes are members of a small family of birds, Turnicidae, of the order Charadriiformes collectively referred to as shorebirds.
Species of the Turnicidae resemble, but are not closely related to, the quails of Phasianidae.

The species of this family inhabit warm grasslands in Asia, Africa, Europe, and Australia.

Turnicidae is from Turnix abbreviation from genus Coturnix, quail(Coturnix is the Latin for the common quail); coined to reflect the quail-like appearance and lack of hind-toe.
hemipodes: Greek hemi half, semi; podes from Greek pous, podos foot (Latin pes).

Vanellus is the genus of waders which provisionally contains all lapwings except red-kneed dotterel, Erythrogonys cinctus. 

1/ River lapwing (Te cựa, Vanellus duvaucelii)

2/ Northern lapwing (Te mào, Vanellus vanellus), also known as the peewit or pewit, tuit or tewit, green plover, or (in Ireland and Great Britain) pyewipe or just lapwing

3/ Grey-headed lapwing (Te vàng, Vanellus cinereus)

4/ Red-wattled lapwing (Te vặt,Vanellus indicus)

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”).
