About These Birds
Japanese Woodpigeon
Japanese Woodpigeon (Columba janthina) — 37–43 cm. Entirely dark glossy purplish-black with green-and-purple iridescence; heavy yellow-red bill. Inhabits forests of the Japanese island chain from Kyushu south through the Ryukyus. Frugivore. Near Threatened; pressured by habitat loss and hunting.
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.
