Helm Field Guides - Birds of the Horn of Africa (revised edition)

The Horn of Africa has the highest endemism of any region in Africa, and around 70 species are found nowhere else in the world. Many of these are confined to the isolated highlands of Ethiopia and Eritrea, but a large number of larks specialise in the arid parts of Somalia and adjoining eastern Ethiopia, whilst the island of Socotra has its own suite of endemic species. The region is also an important migration route and wintering site for many Palearctic birds.
