About These Birds
Picazuro Pigeon
Large, conspicuous pigeon, 33–38 cm, pale grey-brown with white-edged wing feathers forming a scaled pattern and a red orbital ring. One of South America's commonest pigeons, widespread in open woodlands, cerrado, and agricultural land from Brazil to Argentina. Granivore of seeds and grains. Least Concern.
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.
