The green junglefowls are medium-sized, up to 75cm long, birds in the pheasant family Phasianidae.

The colouration of the male green junglefowl differs from that of the female. The male is mainly green and black feathered. Its head is topped by a light blue comb, which turns purple or red towards the top. Its wattle is also of the same colour but is bordered with blue on the edges and yellow closer to the throat. The female is mostly brown with occasional green feathers and has no comb.
