Game theory models predicted that young ravens gain the greatest advantage from hunting in a pack. Now the young birds have figured this out for themselves, and form gangs to oust older raven pairs from tasty carcasses.

Young ravens have transformed their hunt for carrion into a joint venture. Instead of searching on their own, some young ravens form bands of as many as 30 birds.

?This behaviour in young ravens has not been documented before, and came as a surprise to us. But the fun was that our game theory model predicted this behaviour as an alternative strategy for young ravens?, says Jonathan Wright, a biology professor at the Norwegian University of Science and Technology (NTNU).

Wright has been studying the behaviour of young ravens in Wales with his colleague Sasha Dall, of the University of Exeter in Cornwall.
