Rock Pigeon
Few birds have been associated with humans so closely as the Rock Pigeon, better known as the common city pigeon. It has been domesticated and taken around the world, raised for food, trained for homing, racing, and carrying messages, and used in research.
Originally native from Europe to North Africa and India, it now lives in a wild or semi-wild condition in cities all over the world, including most of North America.
In places it has reverted to wild habitats, nesting on cliffs far from cities.
