White-tailed Shrike

The white-tailed shrike (Lanioturdus torquatus) is a small passerine bird from the family Platysteiridae. It is also known as the chatshrike or ground batis. It occurs only in western Angola and Namibia in thorn scrub. It forages from ground level, where it hops about in large bounds and upright posture, to 25m above ground, scanning for insects. The very short tail, with a small black mark at the tip of the central two feathers, is always carried down, never sticking up. Its range of calls includes loud ringing territorial whistles.

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