Andean Cock-of-the-rock

The Andean Cock-of-the-rock is one of South America's most spectacular songbirds, found in humid montane cloud forest and rocky ravines along the Andes. Males possess a brilliant orange plumage and an extraordinary flattened, disc-shaped crest that gives the head a distinctive half-moon silhouette, nearly obscuring the bill entirely.

Males gather at traditional display grounds called leks, where they perform elaborate courtship displays, bobbing, hopping, and calling to compete for the attention of visiting females, a behavior that has made the species a celebrated wildlife-watching attraction across its range.

• Male body is a vivid, saturated orange from head to breast and rump
• Crest is a large, flattened, disc-shaped structure of modified feathers running from the bill to the crown, nearly hiding the bill in profile
• Wings are black with a distinctive pale gray or silvery band across the secondaries, contrasting with the orange body
• Tail is black, short relative to the body
• Female is a much duller brownish-olive overall, lacking the crest's exaggerated shape and the bright orange tones, providing camouflage while nesting
• Distinguished from the Guianan Cock-of-the-rock by its deeper orange (rather than orange-yellow) tone and by range, as the two species do not naturally overlap

Adult males display the vivid orange body, black wings with a silvery band, and oversized disc-shaped crest described above, plumage that is fully developed only in mature males and used prominently in lek displays. Females are uniformly dull brownish-olive with only a small crest, offering effective camouflage at the nest. Juveniles resemble females, with young males gradually acquiring the bright orange plumage and full crest over a period of a few years as they mature.

This species inhabits humid montane cloud forest, often along rocky ravines, cliffs, and streams, on the eastern and western slopes of the Andes from Colombia south to Bolivia. It is largely resident, remaining within forested elevational bands, with males returning repeatedly to the same lek sites across breeding seasons.

Andean Cock-of-the-rocks feed mainly on fruit, supplemented with some insects and small vertebrates, foraging within the forest canopy and understory. Males gather at communal leks, performing bobbing, hopping, and wing-snapping displays accompanied by harsh, guttural calls to attract females. Females build cup nests of mud and plant fiber on rock faces or cliff ledges near streams, and they raise the young alone.
