"Several of the areas endemic birds have very limited ranges; for example, the Taita thrush (Turdus helleri, CR) and Usambara akalat (Sheppardia montana, EN), occur only in a few square kilometers of forest in the Taita Hills and West Usambaras, respectively, while the Uluguru bush-shrike (Malaconotus alius, EN) lives only in a single forest reserve in the Uluguru Mountains."
