There is no strict division between pigeons and doves, which share certain features.

These features include their small, rounded heads, small, slim bills with a small fleshy patch at the base, rounded bodies with dense, soft feathers, tapered wings and short, scaly legs, and cooing or crooning calls. The wild rock dove has long been domesticated and ‘escaped’ to live wild as the familiar town pigeon. There are many species all over the world.
