Data from: Phylogeny and new taxonomy of the Booted Eagles (Accipitriformes: Aquilinae)

We present a phylogeny of all booted eagles (38 extant and one extinct species) based on analysis of published sequences from seven loci. We find molecular support for five major clades within the booted eagles: Nisaetus (10 species), Spizaetus (4 species), Clanga (3 species), Hieraaetus (6 species) and Aquila (11 species), requiring generic changes for 14 taxa. Additionally, we recommend that the Long-crested Eagle (Lophaetus occipitalis) and the Black Eagle (Ictinaetus malaiensis) remain in their monotypic genera, due to their distinctive morphology. We apply the recently resurrected genus Clanga for the spotted eagles (previously Aquila spp.) to resolve the paraphyly of the genus Aquila such that the clade including the Booted Eagle (H. pennatus), Little Eagle (H. morphnoides), Pygmy Eagle (H. weiskei), Ayres’s Eagle (H. ayresii) and Wahlberg’s Eagle (H. wahlbergi) can remain in the genus Hieraaetus. The Rufous-bellied Eagle should be retained in the genus Lophotriorchis. For consistency in English names, we recommend that the term “hawk-eagles” be used only for the species in the genera Nisaetus and Spizaetus. We suggest following new or modified English names: Cassin’s Eagle (Aquila africana), Bonaparte’s Eagle (A. spilogaster), Ayres’s Eagle (Hieraaetus ayresii), and Black-and-chestnut Hawk-Eagle (Spizaetus isidori).

本研究基于7个基因座（locus，复数形式为loci）的已发表序列分析，构建了全部靴雕（booted eagle）的系统发育关系，该类群涵盖38个现存物种与1个灭绝物种。研究结果为靴雕内部的5个主要演化支提供了分子生物学支持，分别为鹰雕属（Nisaetus，含10个物种）、美洲隼雕属（Spizaetus，含4个物种）、斑雕属（Clanga，含3个物种）、隼雕属（Hieraaetus，含6个物种）以及雕属（Aquila，含11个物种），该结果要求对14个类群进行属级分类调整。此外，鉴于长冠雕（Long-crested Eagle，Lophaetus occipitalis）与黑雕（Black Eagle，Ictinaetus malaiensis）具有独特的形态特征，本研究建议将二者保留在各自的单型属中。为解决雕属（Aquila）的并系问题，本研究将近期恢复有效性的斑雕属（Clanga）应用于斑雕类群（原隶属于雕属的Aquila物种），使得包含靴雕（Booted Eagle，Hieraaetus pennatus）、小雕（Little Eagle，Hieraaetus morphnoides）、侏雕（Pygmy Eagle，Hieraaetus weiskei）、艾氏雕（Ayres’s Eagle，Hieraaetus ayresii）以及瓦尔贝格雕（Wahlberg’s Eagle，Hieraaetus wahlbergi）的演化支，仍可保留在隼雕属（Hieraaetus）内。棕腹雕（Rufous-bellied Eagle）应保留在棕腹雕属（Lophotriorchis）中。为统一英文命名规范，本研究建议仅将"hawk-eagles"这一称谓用于鹰雕属（Nisaetus）与美洲隼雕属（Spizaetus）的物种。本研究建议采用以下更新或修订后的英文名称：卡辛雕（Cassin’s Eagle，Aquila africana）、波拿巴雕（Bonaparte’s Eagle，Aquila spilogaster）、艾氏雕（Ayres’s Eagle，Hieraaetus ayresii）以及黑栗鹰雕（Black-and-chestnut Hawk-Eagle，Spizaetus isidori）。
