Guianan cocks-of-the-rock breed early in the year, and the females lay their eggs around March, nesting in rocky areas. During the height of mating season, males gather in leks with multiple males defending a social display arena of much greater area than that of a lone male. The males each have their own area on the forest floor where they make their courts. The size of each court is about in diameter, and the next bird is often about away. The females and males live separately; only when it is time to mate do females fly over to observe and choose a male. When this occurs, the females tap the males from behind and insemination quickly follows. When females approach a lek, the males stand firmly and present themselves rigidly.
