Restricted-range species Two of the EBA's restricted-range bird species are particularly associated with Afromontane habitats in the northern mountains of Somalia: Turdus ludoviciae is locally very common in mountain-top juniper Juniperus forest, and Carduelis johannis is found within juniper forest as well as in the open, rocky areas which lie adjacent to it (Ash and Miskell 1981). The extent of land within their altitudinal ranges is shown on the map by the 1,500-m contour, but within this area juniper forest is highly restricted and localized, and both of these species are known from no more than a handful of sites. Columba oliviae has a more coastal distribution, and usually occurs at relatively low altitudes along both the north and east coasts of Somalia (Ash and Miskell 1983, Collar and Stuart 1985). Another taxon confined to Afromontane habitats in this EBA which was considered to be a full species by Sibley and Monroe (1990, 1993), Archer's Buzzard Buteo archeri, is here treated as a form of the widespread Augur Buzzard B. augur, following Dowsett and Dowsett-Lemaire (1993). |
