The Feral or common Town Pigeon, also called Feral Dove and domestic Dove (there is no genetic difference between a Pigeon and a Dove), is descended from the wild Rock Dove. Feral Pigeon genes have been diluted by domestic breeding for homing/racing/message-carrying/fancy plumage and other traits and the feral escapees and hybrids now common worldwide, particularly in cities, come in various patterns and colours. Rock Dove ancestry shows in the basic pale grey plumage with iridescent green and purple neck and two black wing bars.
