Evolution and Systematics
Discussion of Phylogenetic Relationships
Cotingidae was once home, in some classifications at least, to a number of taxa now assembled into a new family, Tityridae, as well as the enigmatic and endangered Calyptura cristata. It has now been pared back to a clearly monophyletic group. Phibalura has not been sampled in any modern analysis; though clearly a cotinga, its position is unclear; it has been suggested to be close to Ampelion.

The cotingas are a large family of passerine bird species found in Central America and tropical South America. Cotingas are birds of forests or forest edges, which mostly eat fruit or insects and fruit. Comparatively little is known about this diverse group, although all have broad bills with hooked tips, rounded wings, and strong legs. They may be the most diverse passerine family in body size, ranging from the 8-cm kinglet calyptura to the 50-cm male Amazonian umbrellabird, although the smaller bird may not be a true cotinga.
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. Some, like the bellbirds and the screaming piha, have distinctive and far-carrying calls. The females of most species are duller than the males.
Most species are polygynous, and only the females care for the eggs and young. Both brilliant male colors and loud vocalizations are the result of sexual selection. Many have striking courtship displays, often grouped together in leks. In such canopy-dwelling genera as Carpodectes, Cotinga, and Xipholena, males gather high in a single tree or in adjacent trees, but male cocks-of-the-rock, as befits their more terrestrial lives, give their elaborate displays in leks on the ground.
Nests range from tiny to very large. Many species lay a single egg in a nest so flimsy that the egg can be seen from underneath. This may make the nests hard for predators to find. Fruiteaters build more solid cup nests, and the cocks-of-the-rock attach their mud nests to cliffs. The nests may be open cups or little platforms with loosely woven plant material, usually placed in a tree. The clutches comprise one to four eggs. Incubation typically takes fifteen to twenty-eight days. Fledging usually occurs at 28-33 days.
Deserts, open woodlands, coastal mangroves, and humid tropical forests. Cotingas face very serious threats from loss of their habitats.
Taxonomy and systematics
A number of species previously placed in this family have recently been placed in the family Tityridae (genera Laniisoma, Laniocera and Iodopleura) or incertae sedis (genera Oxyruncus, Phibalura and Calyptura).
