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.)
“I have a mind myself and recognize
Mind when I meet with it in any guise.
No one can know how glad I am to find
On any sheet the least display of mind.”
—Robert Frost (1874–1963)
