[edit] Identification[edit] DistributionArgentina, Bolivia, Brazil, Colombia, Ecuador, Paraguay, Peru, and Venezuela. [edit] Taxonomy[edit] Percnohierax vs. ButeoMolecular evidence by Reising et al. (2003) presented evidence for Buteo being polyphyletic in its current treatment. According to the data, Buteo could retain its monophyly if the Roadside Hawk was placed in the monotypic genus Rupornis and the White-rumped Hawk was placed in the monotypic genus Percnohierax. Alternatively, if these two species stayed in Buteo, genera Parabuteo and Geranoaetus would need to be placed in Buteo to avoid paraphyly. At present most authorities keep the White-rumped Hawk in Buteo, and the Opus follows in this consensus. [edit] HabitatMoist montanes.
