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:
“Passionate love, I take it, rarely lasts long, and is very troublesome while it does last. Mutual esteem is very much more valuable.”
—Anthony Trollope (1815–1882)
“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)
