Nanda et al. 2006. "The karyotypes of most birds consist of a small number of macrochromosomes and numerous microchromosomes. Intriguingly, most accipitrids which include hawks, eagles, kites, and Old World vultures (Falconiformes) show a sharp contrast to this basic avian karyotype. They exhibit strikingly few microchromosomes and appear to have been drastically restructured during evolution." Nanda, I.; Karl, E.; Volobouev, V.; Griffin, D.K.; Schartl, M.; Schmid, M. (2006).
