Mutual Display
Where male and female pair up for the breeding season, or longer, the pair-bond between the two is reinforced by doing a mutual display. Such a display often consists of synchronous actions like calling and head bobbing, or one partner repeating the motion of the other. Birds are especially well known for this type of behaviour: albatrosses, penguins and grebes are three such examples.
