Grey peacock-pheasant 
(Gà tiền xám or Gà tiền mặt vàng, Polyplectron bicalcaratum), also known as Burmese peacock-pheasant

The grey peacock-pheasant (Polyplectron bicalcaratum), also known as Burmese peacock-pheasant, is a large Asian member of the order Galliformes.

The term "Galliformes" is derived from the Latin word gallus, meaning "rooster" or "chicken," combined with forma, meaning "form" or "shape". Therefore, Galliformes literally means "chicken-shaped" or "rooster-like," describing this order of birds that includes domestic fowl and related species like turkeys, quail, and pheasants. 
Phasianidae from Phasianus: Latin for "pheasant", derived from the Ancient Greek φἀσιἀνος, phāsiānos, meaning "(bird) of the Phasis", the River Phasis (now the Rioni) in Colchis on the east coast of the Black Sea (now western Georgia).
The name combines the Ancient Greek polus meaning "many" with plēktron meaning "cock's spur".
The specific epithet bicalcaratum combines the Latin bi meaning "two" with calcar, calcaris meaning "spur".
