| Laniarius liberatus Smith, Arctander, Fjeldsa & Amir, 1991 |
The Bulo Burti Boubou (Laniarius liberatus) is a medium-sized passerine bird in the bushshrike family. It remains known only from central Somalia, 140 km inland in Hiiraan gobolka (region) near Buuloburde (Buulobarde, Bulo Burti) on the Shebelle River.
This species is known from a single individual trapped in 1988, and was described using blood and feather samples to provide a DNA sequence. Contrary to the requirements of the International Code of Zoological Nomenclature, no specimen (either the bird itself or a part thereof) was retained as a type; the bird itself was released back into the wild in 1990 because the scientists who caught it felt that the species was very rare, and the blood and feather samples were destroyed in the process of sequencing. The species name of liberatus ("the liberated one") was given due to this fact. It is critically endangered and it was not found during searches in 1989 and 1990. It resembles the Red-naped Bush-shrike L. ruficeps but has no red nape, is black, not grey, on the mantle, and is washed buffy-yellow on throat and breast.

[edit] Taxomical debate
A 2008 study claimed that a new review of the molecular data revealed the identity of the Bulo Burti Boubou as a colour-morph of Laniarius (aethiopicus) erlangeri. If this study is proved to be accurate it would be make the Bulo Burti Boubou an invalid species.[1]
