About These Birds
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.
Emerald-spotted Wood-dove
Small dove, 20–22 cm, grey-brown with two iridescent green wing spots and a pale grey head. Widespread in sub-Saharan Africa from Senegal to Somalia and south to South Africa, in woodland, savanna, and forest edge. Granivore of seeds and termites on the ground. Least Concern.
