The handsome cocks of this endemic species, the national bird of Sri Lanka, are remarkably similar to those of domestic chickens. The longish plumage on the breast and upperparts is mainly a rich, fiery yellow to coppery orange with golden streaks, while the abdomen, flanks and bushy tail are a dark metallic purplish-black. The bare facial skin and two lappets hanging from the throat are red, and a fleshy red crest (comb) with central yellow patch adorns the crown. In summer, after the main breeding season, males slowly moult and their comb shrinks in size. The female is much smaller than the male and has no lappets and only a tiny comb, a small purplish-black lump behind the beak. The hen is mostly brown with a darker tail and bold brown and buff barring on the wings.
