Scientists examining the ticklish subject have offered assorted explanations: mustaches are telltale signs of political conservatism or father worship, emblems of confident nonconformity, or "epigamic adornments designed to win mates, like phosphorescence in fireflies."

A dummy Bell Vireo elicited both agonistic and epigamic behavior from nesting pairs, depending on the phase of the nesting cycle.

Within the scope of my research it was difficult to detect the over-all sequence of epigamic displays that result in synchronization of the physiological states of the sexes throughout the period of courtship.

A marked similarity will be detected between certain basic elements of aggressive and epigamic displays.

Such similarities suggest either a common origin for certain aggressive and epigamic displays or the derivation of one from the other.
