The Udzungwa partridge (Xenoperdix udzungwensis, VU) is known only from a single forested area on the Udzungwa Mountains, and the Uluguru bush shrike (Malaconotus alius, EN) is confined to one forest reserve on the Uluguru Mountains, of less than 100 km2 forest area.

Two of the birds, the Udzungwa forest-partridge (Xenoperdix udzungwensis) and the African tailor bird (Orthotomus metopias), have affinities with living species in Southeast Asia, suggesting an ancient forest connection to the East.
