About These Birds
Croaking Ground Dove
Small dove, 17–20 cm, sandy-grey above, pinkish below, with a yellow bill base and a deep croaking call unlike other Columbina. Confined to arid coastal deserts and dry valleys from Ecuador to northern Chile. Granivore of desert seeds and plant material. 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.
