Koblik, A. E., 2007. Taxonomical revision of genus Emberiza sensu lato L. (Emberizidae, Aves). Comments to the checklist of the birds of Russian Federation. Ornitologiya 34 (2): 141-163.
Summary
The level of ecological and morphological diversity of the Old World Buntings Emberiza sensu lato suggests that this group has diverged beyond the genus scale. Variability of the bill structure shows that method of food processing in the bill is greatly dependent on the trophic preferences of each Bunting species. Both, the level and type of trophic specialization are reflected in habitat distribution and breeding range position, seasonal migrations and other ecological and morphological traits. Parallel and convergent evolution are both also common within the group of Buntings. Molecular data also show high level of isolation in philums of Old World Buntings. Thus, a taxonomical revision splits the Emberiza sensu lato genus into the following genera: Miliaria, Emberiza sensu stricto (with 5 subgenera), Granativora, Cristemberiza, Schoeniclus, and Ocyris (with 4 subgenera). Several of the defined genera of Old World Buntings may share a recent common ancestor with other genera of New World Sparrows rather than with other genera of Old World Buntings.
