About These Birds
Red-billed Pigeon
Medium pigeon, 30–34 cm, grey-brown with a reddish-purple breast and flanks, and a distinctive red bill with a yellow tip. Inhabits tropical lowland and foothill forests from the southwestern United States (rare vagrant) through Mexico and Central America to Costa Rica. Frugivore of forest fruits. 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.
