About These Birds
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.
Thick-billed Ground-pigeon
Stout, medium-large ground pigeon, 28–32 cm, with olive-brown upperparts, a thick pale bill, white facial markings, and rufous-barred underparts. Restricted to dense lowland and foothill rainforest of New Guinea. Terrestrial forager of seeds, fallen fruits, and invertebrates on the forest floor. Least Concern.
