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:
“True love does not quarrel for slight reasons, such mistakes as mutual acquaintances can explain away, but, alas, however slight the apparent cause, only for adequate and fatal and everlasting reasons, which can never be set aside.”
—Henry David Thoreau (1817–1862)
“Life is extraordinarily suave and sweet with certain natural, witty, affectionate people who have unusual distinction and are capable of every vice, but who make a display of none in public and about whom no one can affirm they have a single one. There is something supple and secret about them. Besides, their perversity gives spice to their most innocent occupations, such as taking a walk in the garden at night.”
—Marcel Proust (1871–1922)
