The Red Junglefowl is a name used for both the ancestral stock of the domestic chicken and for feral populations derived from introduced domestic chickens. Smaller in size and slimmer than most chicken breeds, the Red Junglefowl has buffy or bronze neck feathers extending down over the back and a metallic blue to green arching tail. Native of southeast Asia from India through southern China and down to Indonesia, it has become feral in several regions around the world including Hawaii and the Caribbean. Feral birds are often very difficult to distinguish from free-ranging domestics and frequently both inhabit the same island, though feral birds are often secretive and difficult to see. In the Caribbean there are feral populations in Hispaniola, Puerto Rico, Guadeloupe. and the Grenadines.
