The white rumped warbler is an unusual species in where the male seduces other males for the attention of females. During mating season, the more submissive warbler will seduce a potential mate through dance by gyrating and by lifting his rear up and down. The blue bib on its back draws the eye from the shoulders down the spine; as the skin ripples from movement, it mesmerizes other males. When the warbler flashes his white rump at his suitor, it indicates that the suitor has pleased him and wishes for his attention. If interested back, the suitor will go into a frenzy at being shown a glimpse of the warblers sex organs and will push him down, cover him with his body, and mate with him vigorously.
