pied crow
The Pied Crow (Corvus albus) is a widely distributed African bird species in the crow genus.
Structurally, the Pied Crow is perhaps better thought of as a small crow-sized Raven, especially as it can hybridise with the Somali Crow (Dwarf Raven), Corvus edithae where their ranges meet in the Horn of Africa. Its behaviour though is more typical of the Eurasian Carrion Crows and it may perhaps prove to be a modern day link (along with the Somali Crow) between the Eurasian Crows and the Common Ravens.
Pied crow, or snow chested raven, is approximately the size of the European Carrion Crow or a little larger (46-50 cm in length) but has a proportionately larger bill and slightly longer tail, wings and longer legs. As its name suggests, its glossy black head and neck are interrupted by a large area of white feathering from the shoulders down to the lower breast. The tail, bill and wings are black too. It is rarely seen very far from human habitation though is not as tied to the urban way of life in the same way as the House Crow (Corvus splendens) of Asia.
The voice is described as a harsh "ar-ar-ar-ar" or "karh-karh-karh".
