Reproduction
Male golden-collared manakins perform mating dances that involve jumps and flips across tree saplings on the forest floor intense snapping of their wings. The wing snaps are noises, made during the mating dance, that are caused by quick and powerful retractions of their wings. Males have specialized M. scapulohumeralis caudalis and M. supracoracoideus muscles that allow them to pull back their wings forcefully enough to make the snaps.
