About These Birds
Victoria Crowned-pigeon
World's largest pigeon, 73–75 cm, with blue-grey plumage, a deep maroon breast, and the most spectacular crest of any pigeon: a fan of upright blue- grey lacy plumes tipped in white. Inhabits lowland rainforest of northern New Guinea and Biak Island. Terrestrial frugivore. Vulnerable due to heavy hunting pressure and deforestation.
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.
