Identification

The largest of the corvids. Wedgeshaped tail, large head and very heavy bill. In flight, slow, deep, elastic wing-beats, pointedlooking wings. Deep and repetitive call “grrac”. The subspecies tingitanus is slightly smaller, has a shorter bill and is highly gregarious. The largest concentration was of 250 birds, observed on 10.03.93 at Mirador de Benzú (Ceuta).
