About These Birds
Scheepmaker's Crowned-pigeon
Large crowned-pigeon, 66–73 cm, similar to Victoria Crowned-pigeon but with a dark maroon breast and a blue-lace crest lacking the white tips of the Victoria species. Inhabits lowland and hill rainforest of southern New Guinea. Terrestrial frugivore. Vulnerable due to hunting and habitat 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.
