Cracidae comprises 11 genera and 50 species. Taxa within Cracidae are commonly referred to as curassows (Nothocrax, Mitu, Pauxi, Crax), guans (Penelope, Pipile, Aburria, Chamaepetes, Penelopina, Oreophasis) or chachalacas (Ortalis). Cracids are large, blunt-winged birds with long, broad tails. Many species have ornaments (crests or casques) on the head or bill. Cracids are mostly forest dwelling arboreal birds. Unlike many other taxa within Galliformes, many cracids provide parental care to young. Cracids may play an important role as seed dispersers and seed predators in Neotropical forests.
