Captive ravens often squabble, chasing and kicking one another. Afterwards they use touch for reconciliation, when they have fought with an ally. Orliath Fraser from Vienna University, Austria, studied seven captive ravens, and found they were more likely to touch one another with their beaks, or preen one another if they had just fought. Reconciliation is found in mammals, but this is the first recorded observation in birds.
