GALLITO DE ROCA ANDINO

Andean Cock-of-the-Rock
GAllito de ROCA ANDINO

Rupicola peruvianus

It is distributed all across the cloud forest of the Andes. Large passerine of approximately 32 cm (13 in) long and a weight of 265 g (0.6 lb). It is generally shy and inconspicuous This bird exhibits marked sexual dimorphism very evident in plumage color. The male has a large disk-like crest and brilliant scarlet or orange plumage. It has black tail and wings, and pale greyish scapulars. The female is much darker and browner than the male and has a less prominent crest. The bill is yellowish in the male, and dark with a small yellow tip in the female. They produce squawking and grunting calls sometimes similar to the sound of a pig. The Andean cock-of-the-rock eats a diet of fruit, supplemented by insects, amphibians, reptiles, frogs, and smaller mice. Faithful to one partner. The male devotes elaborate display rituals early in the morning or late afternoon to show off its magnificent plumage to the female during mating. When a group of males gathers, competitors perch in pairs or small groups to perform mock confrontational displays, which feature bowing, wing-flapping, head-bobbing, bill-snapping, and bizarre squeaking and grunting calls. They redouble their display efforts when the females approach to assess their performance. Male cocks-of-the-rock are polygamous, and have nothing to do with nesting once mating is done. Female makes the nest in rocky and dark places in forest ravines using her saliva mixed with mud and plant material. Female incubates the eggs and stay with the young for three months.
