Wanna know the secret of raven relationships? It's "never go to the nest angry."
A study by Orlaith Fraser of the University of Vienna in Austria revealed that a pair of ravens that got into a fight with one another reconcile later:
Plenty of primates and other mammals reconcile after a conflict, but previously no birds were known to do so, says Orlaith Fraser of the University of Vienna in Austria.
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.
