. Cotingas are birds of forests or forest edges, that are primary frugivorous. They all have broad bills with hooked tips, rounded wings, and strong legs. They range in size from of the fiery-throated fruiteater (''Pipreola chlorolepidota'') up to of the Amazonian umbrellabird (''Cephalopterus ornatus'').
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. The

'', 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.
The females of both lekking and biparental species are duller than the males.
Breeding
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 15–28 days.
Fledging usually occurs at 28–33 days.
Habitat
Deserts, open woodlands, coastal mangroves, and humid tropical forests comprise their habitats. Cotingas face very serious threats from the loss of their habitats.
