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:
“Then, anger
was a crease in the brow
and silence
a catastrophe.
Then, making up
was a mutual smile
and a glance
a gift.
Now, just look at this mess
that you’ve made of that love.
You grovel at my feet
and I berate you
and can’t let my anger go.”
—Amaru (c. seventh century A.D.)
“If the dignity as well as the prestige and influence of the United States are not to be wholly sacrificed, we must protect those who, in foreign ports, display the flag or wear the colors of this Government against insult, brutality, and death, inflicted in resentment of the acts of their Government, and not for any fault of their own.”
—Benjamin Harrison (1833–1901)
