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.
Bruce's Green-pigeon
Large green-pigeon, 30–33 cm, bright yellow-green with a grey head, yellow eye-ring, and pinkish-yellow bill. Found in dry woodland and savanna across the Sahel and savanna zone of Africa from Senegal to Ethiopia. Frugivore of wild figs and berries in the forest canopy. Least Concern.
