 Male cocks-of-the-rock are polygamous, and have nothing to do with nesting once mating is done. The male ’ s energy instead is devoted to very elaborate display rituals that show off its magnificent plumage. These displays take place in communal leks, where males gather to challenge rivals and beckon the females. The males are easily disturbed, so their behavior is not easy to see. One study reported that the display activity is dependent on light intensity, with the morning display period occurring during the same light intensity level as the afternoon period.
