About These Birds
Bonin Woodpigeon
Bonin Woodpigeon (Columba versicolor) — ~45 cm. Extinct. Inhabited Nakodo-jima and Chichi-jima in the Bonin (Ogasawara) Islands, Japan. Dark iridescent plumage; last recorded in 1889. Driven to extinction by hunting and habitat clearance following colonisation of the islands.
Rock Pigeon
The rock pigeon is the ancestor of all domestic pigeon breeds and one of the most abundant birds in cities worldwide. Pigeons have served humans as messengers, food, and subjects for scientific research — their homing ability and vision have been studied extensively. Darwin's study of pigeon breeding contributed to his theory of evolution.
