An example of such would be the cotinga family, to which the Guianan Cock-of-the-rock belong.

In one study, female Guianan Cock-of-the-rock displayed sexual selection based off sequential comparisons or threshold standards.

Guianan Cock-of-the-rock), and some species of parrots.

Guianan Cock-of-the-rock are frugivorous, but data collected from droppings also suggest that this species does not exclusively consume fruits.

Just south of the lodge, I saw the country's most iconic hue - the bright orange of the Guianan cock-of-the-rock.

Unlike other species of the family Cotinga, the Guianan Cock-of-the-rock makes its nest on rocky cliff faces and caves rather than in the trees.

The wildlife is very diverse, with some peculiar species, like the Neblina Uakari and the Guianan Cock-of-the-rock.

Guianan Cock-of-the-rock (Rupicola rupicola)

In other species such as the Guianan Cock-of-the-rock, as well as other lekking species, sexual conflict may not even manifest itself in parental care.

Studied the behavior of the rare neotropical bird, the Guianan Cock-of-the-Rock (Rupicola rupicola) funded by National Geographic Research.

In contrast to the ducks, many species of the Cotinga family, such as the Guianan Cock-of-the-rock retain their exuberant plumage, thus showing the diversity of the class Aves.

One possible advantage to lek formation in Guianan Cock-of-the-rock is severe selection and consequent rapid evolutionary advancement, all of which is possible due to the high expendability of males.

Fairly common locally in its large range, the Guianan Cock-of-the-rock is in the category of Least Concern on the IUCN Red List of Threatened Species.

The males of many species, such as the Guianan Cock-of-the-rock, are brightly coloured, or decorated with plumes or wattles, like the umbrellabirds, with their umbrella-like crest and long throat wattles.

As suggested by its name, the Guianan Cock-of-the-rock is found in the Guianan Shield, occurring in French Guiana, Suriname, Guyana, southern Venezuela, eastern Colombia and northern Amazonian Brazil.

However it is also shown by birds of other families, such as the Ruff, Great Snipe, Guianan Cock-of-the-rock, Musk Ducks, Hermit hummingbirds, Manakins, birds of paradise, Screaming Pihas and the Kakapo.

The natural world is replete with examples of signals, from the luminescent flashes of light from fireflies, to prominent mating displays of birds such as the Guianan Cock-of-the-rock, which gather in leks, or the dancing patterns of the Blue-footed Booby.

Since no successful attempts to breed Guianan Cock-of-the-rock in captivity have succeeded, there is speculation that the simulation of male-male competition is important in lek formation and breeding, and that artificial environments may not properly reconstruct or imitate the natural environments.
