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, 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.
Habitats include various open and semi-open environments, including agricultural and urban areas. Cliffs and rock ledges are used for roosting and breeding in the wild. Originally found wild in Europe, North Africa, and western Asia, feral Rock Pigeons have become established in cities around the world. The species is abundant, with an estimated population of 17 to 28 million feral and wild birds in Europe.
The adult of the nominate subspecies of the Rock Pigeon is 32–37 cm (12-14½ in) long with a 64–72 cm (25-28 in) wingspan.It has a dark bluish-gray head, neck, and chest with glossy yellowish, greenish, and reddish-purple iridescence along its neck and wing feathers. The iris is orange, red or golden with a paler inner ring, and the bare skin round the eye is bluish-grey. The bill is grey-black with a conspicuous off-white cere, and the feet are purplish-red.
The adult female is almost identical to the male, but the iridescence on the neck is less intense and more restricted to the rear and sides, while that on the breast is often very obscure.The white lower back of the pure Rock Pigeon is its best identification character, the two black bars on its pale grey wings are also distinctive. The tail has a black band on the end and the outer web of the tail feathers are margined with white. It is strong and quick on the wing, dashing out from sea caves, flying low over the water, its lighter grey rump showing well from above.
