Breeding edit
After mating, male cocks-of-the-rock are polygamous and do not participate in nest building. Instead, the male’s energy is focused on intricate display rituals that showcase his amazing plumage. These performances happen in public leks, where men congregate to confront competitors and beckon women. [7] The males’ behavior is difficult to observe since they get upset easily. The display activity is reportedly dependent on light intensity, with the morning display period taking place at the same light intensity level as the afternoon period, according to one study [8]. [13].
Males have been seen to split up into pairs and engage in “confrontation displays” at the lek. They do this by facing one another and simultaneously making different squawking and grunting noises as well as bowing, jumping, flapping, and occasionally even snapping their bills. When the female approaches, she becomes even more intense. The show transforms into a frenzied flurry of color and frantic activity, filling the air with bizarre noises. [8].
Different times of the year and in different places are used for breeding. In Colombia, breeding normally happens from February until July. In Ecuador, the breeding interval spans from July until February. [14].
Description edit Immature male at the
Large passerine, the Andean cock-of-the-rock measures about 32 cm (13 in) in length and weighs about 265 grams (9 3 oz; 0. 584 lb), however the heaviest specimens can weigh up to 300 grams (11 oz; 0), with males being somewhat larger. 66 lb). The bird is one of many species of birds that have noticeable sexual dimorphism. The male’s plumage is brilliant scarlet or orange, and he has a large disk-like crest. He has light greyish scapulars, a black tail, and wings. The female has a less noticeable crest and is noticeably duller and browner than the male. In the male, the bill has a yellowish hue, while in the female, it is dark with a tiny yellow tip. The color of the iris varies significantly depending on gender and subspecies; in males, it can range from red over orange and yellow to bluish-white, while in females, it can be whitish over reddish to brown. In addition to the display calls mentioned in the section below on breeding, when foraging birds are disturbed or in flight, they emit a loud, raucous “tank?” sound. [8][9].
