チャエリガラス Corvus ruficollis

Large and black, almost as big as Common Raven. Its namesake brown neck is only visible at close range in specific lighting conditions. Bill is slightly thinner, tail shorter and less wedge-shaped, and the call is less deep and throaty compared to Common Raven. Found exclusively in arid zones where it breeds on cliffs, trees, and pylons. Moves around in pairs or small groups, but may congregate at abundant food sources in larger groups.
