Somali boubou
The Somali boubou (''Laniarius erlangeri'') is a medium-size bushshrike. It was split from the tropical boubou (''Laniarius aethiopicus'') as a result of DNA sequence analysis,〔Nguembock, B., Fjeldså J., Couloux A., Pasquet, E. (2008) "(Phylogeny of ''Laniarius'': molecular data reveal'' L. liberatus ''synonymous with ''L. erlangeri'' and "plumage coloration" as unreliable morphological characters for defining species and species groups )". PDF ''Mol. Phyl. Evol.'' 48(2): 396-407. 〕 and this change in status was recognized by the International Ornithological Committee in 2008.〔(IOC World Bird List Volume 2 )〕 Two colour morphs are recognized, a predominantly black one and an extremely rare black and yellow morph which was formerly considered a separate species, the Bulo Burti boubou (''Laniarius liberatus''). The Somali boubou is endemic to Somalia. The species epithet commemorates German ornithologist Baron Carlo von Erlanger who collected the holotype near Umfudu in June 1901.〔Carl Hilgert (1908): Katalog der Collection von Erlanger in Nieder-Ingelheim am Rhein. R. Friedlander und Sohn, Berlin (German)〕
==Description==
The adult has glossy blue-black except for white spots on the rump, visible when the wings are spread and the rump feathers are erected. The underparts are white with a buffy or pinkish tinge on the breast and flanks. The bill is black; the eyes are dark reddish-brown. The wings have white median coverts. The juvenile is similar but duller, with a greyish brown bill, the upperparts mottled by yellowish-ochre to tawny feather tips, and dusky-barred flanks. The Somali boubou differs from tropical boubou in that it is smaller and has less white in the wing.
