Along the shore of Lake Awassa, this yellow wagtail walked searching for food. Yellow wagtails are always extra interesting because the subspecies vary so much. One subspecies, 'lutea', which breeds along the Volga, has a completely yellow head; the Scandinavian Yellow wagtail, 'flava', has a blue-gray head; the subspecies 'feldegg', which occurs in the Balkans, has an almost black head, and so on. The variations are many and the researchers disagree on how to draw the boundaries between them. East Africa and the Horn of Africa are in this context an extremely interesting area because several subspecies are wintering here. This individual appears to be of the rare subspecies 'superciliaris' which has been named by the distinctive superciliary. It has a dark head and breeds in the area around the Caspian Sea and the Aral Sea and is thus in Ethiopia on a winter holiday. Nevertheless, it might also be an especially dark variant of the 'flava'... (This shows how hard it is to distinguish between the subspecies).
