Based on the topology obtained, and known phylogenies of the group, a taxonomic rearrangement for the family Accipitridae was proposed comprising 10 subfamilies, two of which each include three tribes: Gypaetinae (Gypaetini, Polyboroidini and Pernini), Macheiramphinae, Aegypiinae, Circaetinae, Elaninae, Harpiinae, Aquilinae, Haliaeetinae, Milvinae and Buteoninae (Buteonini, Circini and Accipitrini). Additional recommendations were made for updating the nomenclature of some genera and species in the Accipitridae.
I have integrated Nagy and Tökölyi (2014) into the discussion of Acciptridae. This lead to a comprehensive reexamination of Acciptiridae...
I'd be cautious with this part of the tree.The Tiny Hawk (and presumably Semicollared Hawk) do not seem closely related to Accipiter (Olson, 2006) and have been placed in the genus Hieraspiza (Kaup 1844, type superciliosa). It has not been clear what they are related to (Kocum, 2006), but the analysis by Nagy and Tökölyi (2014) put them in a group with the chanting goshawks, lizard buzzard (see also Griffiths et al., 2007; Lerner et al., 2008), and a couple of other species.
Magee, May & Moore 2014. The dawn of open access to phylogenetic data. PLoS ONE 9(10): e110268. [article] [pdf]Nagy & Tökölyi did not give an explicit list of the sequences they used. (Unfortunately, this becomes more and more frequent: such lists, which usually appeared in the papers themselves, are now either relegated to online supplementary files [which, depending on the publisher, may or may not be straightforward to access], or omitted altogether. The result being that some papers end up not including anything pointing to the studies that produced the data they are based on. Somewhat disturbing, IMO, but...)
