Parabuteo leucorrhous

Buteo leucorrhous



South America: found in Colombia, Venezuela, Ecuador, Peru, Bolivia, Brazil, Paraguay and Argentina.


This is a monotypic species[1].

Percnohierax vs. Buteo

Molecular 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. Most authorities now place White-rumped Hawk in the genus Parabuteo.
