Andean cock-of-the-rock

Andean cock-of-the-rock also known as tunki (Quechua), is a large passerine bird of the cotinga family native to Andean cloud forests in South America. It is widely regarded as the national bird of Peru. It has four subspecies and its closest relative is the Guianan cock-of-the-rock.

The Andean cock-of-the-rock exhibits marked sexual dimorphism; the male has a large disk-like crest and scarlet or brilliant orange plumage, while the female is significantly darker and browner. Gatherings of males compete for breeding females with each male displaying its colourful plumage, bobbing and hopping, and making a variety of calls. After mating, the female makes a nest under a rocky overhang, incubates the eggs, and rears the young, all by herself.

The Andean cock-of-the-rock eats a diet of fruit, supplemented by insects, amphibians, reptiles, and smaller mice. It is distributed all across the cloud forest of the Andes, having a range of around 260,000 km² (100,000 sq mi). Even though it is being affected by destruction of its habitat, the Andean cock-of-the-rock is not classified as threatened.

Food and feeding

The diet consists mainly of fruit and insects, although small reptiles and frogs have been recorded. The fruits consumed are often from the plant families Lauraceae, Annonaceae, and Rubiaceae, although a few other plant families have also been reported in their diet. They are one of many species recorded following army ants. They occasionally will eat high protein fruits, but they prefer to eat the other fruits on their menu.

habitat

The Andean cock-of-the-rock is distributed in cloud forests of the Andes. It lives in a large range of about 260,000 km² (100,000 sq mi) across Venezuela, Colombia, Ecuador, Perú, and Bolivia, mostly in ravines and forested streams in montane areas at 500 to 2,400 m (1,600 to 7,900 ft) elevation. It typically stays in the lower and middle forest levels, but will range higher in fruiting trees and will sometimes enter and cross clearings. It is generally shy and inconspicuous, often seen only briefly after being flushed out or while swiftly flying down a valley.
