About These Birds
Somali Pigeon
Somali Pigeon (Columba oliviae) — 30–33 cm. Pale grey-brown with a vinous-pink tinge; pale eye; subtle neck gloss. Endemic to northern Somalia on rocky arid hillsides and coastal cliffs. Granivore. A poorly known endemic of the Somali Highlands; status uncertain.
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.
