Somali boubou, Erlanger's boubou, Coastal boubou
The black boubou, Somali boubou, Erlanger's boubou, or coastal boubou (Laniarius nigerrimus ) is a medium-size bushshrike. It was split from the tropical boubou as a result of DNA sequence analysis, and this change in status was recognized by the International Ornithological Committee in 2008. Two colour morphs are recognized, a predominantly black one, the black boubou, and an extremely rare black and yellow morph which was formerly considered a separate species, the Bulo Burti boubou (Laniarius liberatus ). The black boubou is found in Somalia and northern Kenya.
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.
