This paper reviews the identification features of Woodchat Shrikes Lanius senator of the eastern race niloticus. A number of young birds seen in autumn in Britain have apparently shown extensive moult of the juvenile body feathers, a feature associated with niloticus. The equivalent moult in the nominate race occurs on the wintering grounds after migration, and this difference is central to the identification of young birds in autumn. The criteria and guidelines presented here should help observers to identify a potential niloticus, a taxon that is not yet on the British List.
