Andenfelsenhahn

Bestimmung

The Andean cock-of-the-rock is a large passerine, approximately 32 cm (13 in) long and weighing around 265 grams (9.3 oz; 0.584 lb), although males are somewhat larger and the heaviest specimens can reach 300 grams (11 oz; 0.66 lb). The bird is one of many bird species to exhibit marked sexual dimorphism. The male has a large disk-like crest and brilliant scarlet or orange plumage. He has a black tail and wings, and pale greyish scapulars. The female is significantly drabber 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. Depending on gender and subspecies there are significant variations in the color of the iris, ranging from red over orange and yellow to bluish-white in the male, and whitish over reddish to brown in the female. In addition to the display calls described in the breeding section below, foraging birds give a loud querulous "tank?" when disturbed or in flight.

Taxonomie

One of two species in the genus Rupicola, the other being the Guianan cock-of-the-rock, the Andean cock-of-the-rock was first described by English ornithologist John Latham in 1790. It is classified in the Cotingidae, a family of largely frugivorous tropical forest suboscine passerines. The generic name is derived from the Latin stems rupes "rock" or "cliff", and cola "inhabiting", and is derived from its habit of nesting in rock walls. Its specific epithet peruvianus "of Peru" is masculine despite the -a ending of the genus name (in Latin, names in -cola were masculine or neuter); peruviana is seen in older works.<p>Four subspecies are known:

Verbreitung und Lebensraum

The Andean cock-of-the-rock is distributed in the 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.<p>R. p. aequatorialis is the most widespread subspecies, ranging across the Andes of East Colombia to West Venezuela, East Ecuador, and East Peru. The nominate subspecies, R. p. peruvianus has a small range stretching only through the Andes of Central Peru. R. p. sanguinolentus ranges throughout the Andes in West Colombia to Northwest Ecuador. The subspecies R. p. saturatus has a range across Southeast Peru and West Bolivia.
