[edit] Identification

32–37 cm. White lower back, two black bars on pale grey wings, tail is margined with white, lighter grey rump. The head and neck of the mature bird are a darker blue-grey than the back and wings; the lower back is white. The green and lilac or purple patch on the side of the neck is larger than that of the Stock Dove, and the tail is more distinctly banded. These birds come in many different colours, dark grey, light blue/grey, brown, peach, grey and white, pure white and more. Young birds show little lustre and are duller. Eye colour of the pigeon is generally an orange colour but a few pigeons may have white-grey eyes. The eyelids are orange in colour and are encapsulated in a grey-white eye ring. The feet are red to pink.

[edit] Distribution

Southern Europe, North Africa, and into South Asia.

Rock Pigeons have been domesticated for several thousand years; escapees have resulted in feral populations in cities world-wide.
