Laniarius atrococcineus

A bird of the genus Laniarius which was formerly classed with the true shrikes in the family Laniidae, but they and related genera are now considered sufficiently distinctive to be separated from that group as the bush-shrike family Malaconotidae.

One should call it a Crimson-breasted Boubou ;-) because it resembles very much its Laniarius brothers, the Southern Boubou and the Tropical Boubou :O^

As much as I dislike Nossob camp, I have to admit it's perhaps the best place for Crimson-breasted "Shrike" :-0

Sexes are monomorphic with black upperparts to below the eye, black tail and wings showing a white wing stripe. The entire underparts are brilliant crimson except for a yellow morph that occurs occasionally which has lost the ability to transform the yellow food carotinoids into red Astaxanthin based on a gene defect.

The sexes have the same colouration and are indistinguishable from each other. A yellow-breasted form is occasionally seen, and was at first thought to be a separate species. Young birds have a mottled and barred buff-brown appearance with a pale bill.
