鸟类家族Accipitridae在历史上被分为亚科或部落的基础上，如一般相似性，喂养生态和行为。因此，这些群体的单系性是值得怀疑的。最近，出现了三个系统发育分析的大多数属，一个基于骨骼学，一个从一个单一的线粒体基因的DNA序列，和线粒体加核DNA序列的第三个，和由此产生的系统发育是在实质性的分歧有关的组成和基部分支模式的分支，因此需要进一步的分析和确认。在这里，我们使用的DNA序列从大核RAG-1外显子调查这些鸟类的系统发育关系。我们的结果在很大程度上证实了先前的研究，包括核基因。我们发现了一个单系分支，包括secretarybird人马座serpentarius，鱼鹰Pandion haliaetus，和传统的accipitrids的有力支持。然而，人们发现传统上公认的鹰科的每一个亚科都是多系的。食虫性和食腐性物种的小分支，如风筝和旧大陆秃鹫，从家庭的其余部分中分离出来。鸟类和哺乳类捕食者的物种属都是在进化史上相对衍生的（终末）。许多基本分支是世界性的分布，与这些猛禽的巨大流动性相一致。提出了一种新的分类，消除了多系的家族内类群的问题。
The avian family Accipitridae has historically been divided into subfamilies or tribes based on features such as general resemblance, feeding ecology, and behavior. Consequently, the monophyly of those groups has been questionable. Recently, three phylogenetic analyses of a majority of the genera have appeared, one based on osteology, one on DNA sequences from a single mitochondrial gene, and the third on mitochondrial plus nuclear DNA sequences, and the resulting phylogenies were in substantial disagreement concerning the composition and basal branching patterns of the clades and hence require further analysis and confirmation. Here we use DNA sequences from the large nuclear RAG-1 exon to investigate the phylogenetic relationships of these birds. Our results largely corroborated the prior study that included nuclear genes. We found strong support for a monophyletic clade comprising the secretarybird Sagittarius serpentarius, the osprey Pandion haliaetus, and the traditional accipitrids. However, every one of the traditionally recognized subfamilies of accipitrids was found to be polyphyletic. The most basal nodes in the phylogeny separate small clades of insectivorous and scavenger species, such as kites and Old World vultures, from the rest of the family. The speciose genera of bird and mammal predators are all relatively derived (terminal) in the phylogeny. Many of the basal clades are cosmopolitan in their distributions, consistent with the great mobility of these raptors. A new classification is proposed that eliminates the problem of polyphyletic intrafamilial taxa.
