The Wattled Guan inhabits upper tropical and subtropical forests over the Andes from western Venezuela south to southern Peru, mainly at altitudes of 400–2500 m, although there is an exceptional record from 3500 m. As well as primary forest, the species will also tolerate tall second growth. The species’ plumage is basically black and highly glossed, although the tone of this gloss varies throughout the species’ range, from bronzy olive-green in the north to dark blue in the south; also, the bird’s overall size decreases with latitude. However, the most remarkable morphological feature is the pendant yellow wattle, which dangles from the throat. The Wattled Guan’s loud vocalizations and wing-rattling display make it comparatively easily detected, even during short field surveys. Nonetheless, despite a recent explosion in fieldwork within the range of the Wattled Guan, much knowledge of its natural history, especially the species’ breeding biology, remains to gained.
