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.

Famous quotes containing the words mutual and/or display:
“Whoever takes a view of the life of man ... will find it so beset and hemm’d in with obligations of one kind or other, as to leave little room to suspect, that man can live to himself: and so closely has our creator link’d us together ... that we find this bond of mutual dependence ... is too strong to be broke.”
—Laurence Sterne (1713–1768)
“Lovers of painting and lovers of music are people who openly display their preference like a delectable ailment that isolates them and makes them proud.”
—Maurice Blanchot (b. 1907)
