Piping-Guans

The piping guans are a bird genus, Pipile, in the family Cracidae. A recent study, evaluating mtDNA, osteology and biogeography data concluding that the wattled guan belongs in the same genus as these and is a hypermelanistic piping guan. Thus, Pipile became a junior synonym of Aburria, though this conclusion was not accepted by the South American Checklist Committee, or evaluated by the IOC, so the classification remains in Pipile.

The same results also showed that the light-faced taxa pipile, cumanensis and cujubi are not, as was sometimes suggested, conspecific. However, free interbreeding between A. cujubi and A. cumanensis grayi in eastern Bolivia, creating a "hybrid swarm", casts doubt on this conclusion for the two species named.
