Angry ravens might kick and chase each other, but if they are close allies they make up afterwards.
Monitoring a group of seven captive ravens (Corvus corax), Fraser and colleague Thomas Bugnyar found that pairs of birds were likely to be more friendly to each other if they had fought each other in the previous 10 minutes.
“It wasn’t just standard friendly behaviour,” Fraser says. Rather the ravens sat touching each other, and sometimes touched their beaks together or preened each other. Ravens are not tactile like primates, so sitting in contact is a strong social signal.
