  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.del hoyo, j. elliott, a. & christie, d.
