Marine animal studies overview

We studied the display behavior and spatial distribution of the Red-headed Manakin (Pipra rubrocapilla, Pipridae) in the Atlantic Forest of the state of Rio de Janeiro, Brazil. The average distance between display sites was 72.5 ± 34.1 m (n = 11, range = 34.0–157.0 m). The study area included one 13-site lek and two solitary display sites. All sites of the same lek were within earshot of at least one other site. Males occupied the same display sites between years. The dispersion pattern of males is typical of exploded or dispersed leks. Males were more likely to interact with their nearest neighbor than with males from more distant display sites. Red-headed Manakin lekking behavior is remarkably complex, including 11 display elements, two of them not found in other members of the P. erythrocephala clade, nine vocalizations, and one mechanical sound previously undescribed in the Red-headed Manakin. The males performed both solitary displays and coordinated displays with other males on both their own display sites and on those of the other males. Most of the time, two definitive-plumaged males displayed together. The displays, vocalizations, and mechanical sound recorded in this study contribute to our understanding of the evolution of display behavior in manakins, mainly to the members of the P. erythrocephala clade.
