Molecular phylogeny of the genus Buteo (Aves: Accipitridae) based on mitochondrial marker sequences [link]Paper  doi  abstract   bibtex   
DNA sequences of the mitochondrial nd6 gene and the non-repetitive part of the pseudo-control region (ΨCR) were isolated from 101 individuals to analyze the phylogenetic relationships among all buzzards of the genus Buteo and other buteonine genera. Comparisons of the two marker sequences indicate that the ΨCR evolved two times faster than the nd6 gene. The ΨCR proved to be an efficient, neutral genetic marker sequence for phylogenetic analyses at the intrageneric level, especially suitable for analyses based on old tissues, where only short fragments can be obtained. The molecular data set implies a neotropical origin of the genus Buteo. Monophyly of the genus Buteo as currently defined is contradicted due to the positions of Asturina nitida, Geranoaetus melanoleucus, Buteo magnirostris, and Buteo leucorrhous. These findings suggest several taxonomic consequences. A. nitida and G. melanoleucus should be included into the genus Buteo. Moreover, B. leucorrhous should be transferred into the genus Percnohierax (which clusters with Parabuteo), and B. magnirostris into the genus Rupornis. According to this classification of the genus Buteo, the basal lineage of the genus is formed by a clade containing Buteo polyosoma, Buteo poecilochrous, and Buteo melanoleucus. The “woodland buteos” form a paraphyletic assemblage with B. magnirostris as a clearly separated lineage basal to the genus Buteo.
