PhysOrg Posted April 17, 2014 Share Posted April 17, 2014 If a restaurant owner fails to pay the protection money demanded of him, he can expect his premises to be trashed. Warnings like these are seldom required, however, as fear of the consequences is enough to make restaurant owners pay up.

If the host birds throw the cuckoo's egg out, the brood parasites take their revenge by destroying the entire nest. Consequently, it is beneficial for hosts to be capable of learning and to cooperate. Previously seen only in field observations, scientists at the Max Planck Institute for Evolutionary Biology in Plön have now modelled this behaviour mathematically to confirm it as an effective strategy.
