About These Birds
Yellow-legged Pigeon
Yellow-legged Pigeon (Columba pallidiceps) — 37–40 cm. Pale grey head; dark back; pale underparts; distinctive yellow-orange legs and feet; red bill. Inhabits forest and forest edge on islands of the Bismarck Archipelago and Solomon Islands. Frugivore. Vulnerable due to ongoing deforestation and hunting pressure.
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.
