Cracid

Indeed, if anything it^([the chachalaca]) is further from the Galliformes than the duck; but because of the slight uncertainties in the method Prager and Wilson argued for a three-way split between ducks, cracids, and non-cracid galliforms.

Cracraft (1973b, p. 507) asserted that Gallinuloides was closer to phasianids than cracids, but never presented evidence to substantiate his claim.

Two of the five Galliform families, the cracids (guans, curassows and chachalacas) and the New World quails, are confined to the Americas, with most species in Central and especially South America.
