A male Lesser Bird of Paradise (Paradisaea minor) displays in a lowland rainforest near Oransbari, WNG. This species typically displays in a communal lek of two or more males in the upper canopy.

Male Red Bird of Paradise (Paradisaea rubra) performs an inverted display on bare branches emerging from the canopy. This species is endemic to the Raja Ampat Islands in WNG.

In many polygamous birds of paradise, the males establish solitary display courts. In the remainder, males cluster their display courts into what is termed a lek. For instance, in the King Bird of Paradise, the males form display pairs, typically spaced about 70 meters apart but in close vocal contact. Raggiana Birds of Paradise cluster into a single canopy tree, and as many as 15 males use the lek space for calling and display. This is true lek behavior, and it is remarkable to behold in an early morning in the forest. The males arrive in the lek tree and begin calling before dawn. Then the dominant males take their perches in the center of the lek and begin displaying to one another and to visiting females. The females sneak into the lek, mate, and then depart. The males leave the lek only to forage in nearby fruit trees. The males attend the lek for as many as six months a year.
