Sie tragen meist Kopfhauben aus aufstellbaren, am Ende nach vorn eingerollten Federn. Die Geschlechter zeigen einen deutlichen Dimorphismus: das Gefieder der männlichen Vögel ist glänzend schwarz mit Ausnahme der weißen Bauchseite, die Wachshaut an der Schnabelbasis leuchtet kräftig gelb (Gelblappenhokko, Crax daubentoni, 83 cm), blau (Blaulappenhokko, C. alberti, 90 cm) oder rot (Knopfschnabel-Hokko oder Karunkelhokko, C. globulosa, 90 cm) und trägt zumeist einen fleischigen Höcker. ...

... Gelblappenhokko
Crax daubentoni • The Yellow-knobbed Curassow • Le hocco de Daubenton
Der in seinem Ursprungsgebiet potenziell gefährdete Gelblappenhokko ist ein großer, attraktiver Hühnervogel, der sich gut als Botschafter für den Schutz der vielfach gefährdeten Fauna seines Ursprungsgebiets und deren Lebensräume eignet, insbesondere wenn er freilaufend in einer Tropenhalle oder, wie z.B. im CERZA-Zoo in Lisieux in einem begehbaren Gehege präsentiert wird. Er ist allerdings in europäischen Zoos nicht allzu häufig zu sehen.

https://en.wikipedia.org/wiki/Yellow-knobbed_...
The yellow-knobbed curassow (Crax daubentoni) is a large species of bird found in forest and woodland in Colombia and Venezuela. It feeds mainly on the ground, but flies up into trees if threatened. Its most striking features are its crest, made of feathers that curl forward, and the fleshy yellow knob at the base of its bill. Females lack this fleshy yellow knob, but otherwise resemble the male in the plumage, being overall black with a white crissum (the area around the cloaca). The adult is 84–92.5 cm (33–37 in)[2] and weighs about 2–3 kg (4.4-6.6 lbs).[3] It eats fruits, leaves, seeds, and small animals. Unlike most other gamebirds, curassows nest off the ground, with both sexes helping in the construction. The female lays just 2 eggs - a tiny clutch compared to those of many ground-nesting gamebirds. ...

... Behavior
Since the Cracidae are so shy and generally avoid humans, little is known about their social life. There are indications that at least some species live in polygamy; male yellow-knobbed curassows (Crax daubentoni), for example, may be found in the breeding season with three, four, or occasionally more hens. Guans are found at all seasons more or less socially in flocks, and their nests sometimes stand together in groups.
The vocalizations of the Cracidae are loud and rarely pleasant to the human ear. In a number of species, the vocal power of the cocks, and sometimes of the hen as well, is increased by a prolonged trachea. It runs far back between skin and breast muscles, and then turns and runs forward to the point of entry into the chest cavity. ...

Yellow-knobbed curassow
Crax daubentoni
Yellow-knobbed curassows live in the forests of Colombia and Venezuela in South America. They are often found near river valleys and water holes during the dry season, or in grassy areas called Llanos.
They are named after the yellow flesh around the beak of a male, called the “cere”. Females can be distinguished from males by their black beaks. Curassows are related to gamebirds such as pheasants and partridges. They forage for food on the ground, eating a varied diet of fruits, seeds and sometimes insects. Curassows may also be found in tall trees where they roost at night, or call to advertise their territory. ...
