Piping guan

The piping guans are a bird genus, Pipile, in the Cracidae family. A recent study (Grau et al. 2005), evaluating mtDNA, osteology and biogeography data (Grau et al., 2005) 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 (Remsen et al., 2007), or evaluated by the IOC, so the classification remains in Pipile.
