Editing Cotinga (section)

==Description==
Cotingas vary widely in social structure. There is a roughly 50/50 divide in the family between species with biparental care, and those in which the males play no part in raising the young.<ref>{{Cite journal | last=Cockburn | first=Andrew | date=2006 | title=Prevalence of different modes of parental care in birds | journal=Proceedings of the Royal Society B: Biological Sciences | volume=273 | issue=1592 | pages=1375–1383 | doi=10.1098/rspb.2005.3458| pmid=16777726 | pmc=1560291 }} Supplementary Material.</ref> The [[purple-throated fruitcrow]] lives in mixed-sex groups in which one female lays an egg and the others help provide insects to the chick.<ref name=PS/>

In cotinga species where only the females care for the eggs and young, the males have striking courtship displays, often grouped together in [[Lek (mating arena)|leks]]. Such [[sexual selection]] results in the males of these species, including the [[Guianan cock-of-the-rock]], being brightly coloured, or decorated with plumes or wattles, like the [[umbrellabird]]s, with their umbrella-like crest and long throat wattles. Other lekking cotingids like the bellbirds and [[screaming piha]], have distinctive and far-carrying calls. In such [[Canopy (forest)|canopy]]-dwelling genera as ''[[Carpodectes]]'', ''[[Cotinga (genus)|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.<ref name=PS>{{cite book | last = Prum | first = Richard O. | author1-link=Richard Prum | author2 = Snow, David W. | author2-link=David Snow (ornithologist) | year = 2003 | title = Firefly Encyclopedia of Birds | chapter = Cotingas | editor = Christopher Perrins | editor-link = Christopher Perrins | pages = [https://archive.org/details/fireflyencyclope0000unse/page/432 432–433] | publisher = Firefly Books | isbn = 1-55297-777-3 | chapter-url-access = registration | chapter-url = https://archive.org/details/fireflyencyclope0000unse | url = https://archive.org/details/fireflyencyclope0000unse/page/432 }}</ref>

The females of both lekking and biparental species are duller than the males.
