Genus: Asturina
Description
If recognized, this monotypic genus would contain the Gray Hawk.
Taxonomy
Asturina vs. Buteo
The Gray Hawk was formerly placed in the monotypic genus Asturina. Riesing et al. (2003) presented genetic data indicating that Asturina is nested within Buteo. This reclassification is supported by virtually all authorities since then: Banks et al. (2006), AOU (2006 supplement), Clements (2007), SACC (2006). The Opus follows in this concensus.
