White-tailed Shrike - This curious bird, which some consider to have close affinities with the batises and others the bushshrikes, was discovered in 1837 by James Edward Alexander in the Naukluft Mountains of Namibia. Waterhouse subsequently described it in 1838, the name Lanioturdus reflecting the uncertainty of its classification, and torquatus denoting 'collared'. The sexes have a similar appearance.
