About These Birds
Grey-capped Emerald Dove
Small, brilliant dove, 23–27 cm; male has iridescent emerald-green back and wings, grey crown, white forehead streak, and pinkish-brown breast.

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.
