The presence of a female influences courtship performance of male manakins

Abstract

ABSTRACT Coordinated courtship displays are a common feature of species forming long-term pair bonds. In lekking species, on the contrary, there are no stable pair bonds because partners meet only to copulate, and males indicate their quality and/or attractiveness to females by displaying morphological and behavioral traits. In some cases, females interact with these displaying males, but little is known about the role of the females in these encounters. In the Neotropical bearded manakins, females join males in their acrobatic courtship displays in the final phase of mate choice. We hypothesize that females participate in the courtship dance to better assess male motor skill by observing male responses to female signals. We filmed at high speed the courtship displays of 2 species of bearded manakins and compared the displays performed by males alone, where the female is absent from the arena, with those performed together with a female. In addition, we compared the movements of the male with those of the...
