The Rock Pigeon (Columba livia), or Rock Dove, is a member of the bird family Columbidae (doves and pigeons). In common usage, this bird is often simply referred to as the pigeon. The species includes the domestic pigeon (including the fancy pigeon), and escaped domestic pigeons have given rise to the Feral Pigeon.
Wild Rock Pigeons are pale grey with two black bars on each wing, although domestic and feral pigeons are very variable in colour and pattern. There are few visible differences between males and females. The species is generally monogamous, with two squabs (young) per brood. Both parents care for the young for a time.
