About These Birds
Sclater's Crowned-pigeon
Large crowned-pigeon, 66–73 cm, with blue-grey body, a deep maroon breast, and a fan-shaped blue crest with lacy blue-grey tips rather than white. Found in lowland forests of southern New Guinea between the ranges of the other southern crowned species. Terrestrial frugivore. Vulnerable due to hunting and forest loss.
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.
