They can glide over large areas and circle in thermals without beating their wings. In spring especially, pairs are seen spinning together high up in the air, half closing their wings, then rolling to the side and making breath-taking dives. They are able to fly a short distance rolled over onto their back. They pair for life and strengthen their bond by fondling, feeding or preening. The Common Raven was for a long time heavily persecuted. Today, however, it is common knowledge that they mainly feed on carrion and only exceptionally kill young and mainly sick animals."}
