Amazon parrots (Genus Amazona) are among the most recognizable and imperiled of all birds. Several hypotheses regarding the evolutionary history of Amazona are investigated using a combined phylogenetic analysis of DNA sequence data from six partitions including mitochondrial (COI, 12S, and 16S) and nuclear (beta-fibint7, RP40, and TROP) regions. The results demonstrate that Amazona is not monophyletic with respect to the placement of the Yellow-faced parrot (Amazona xanthops), as first implied by. In addition, the analysis corroborates previous studies suggesting a Neotropical short-tailed parrot genus as sister to Amazona. At a finer level, the phylogeny resolves the Greater Antillean endemic species as constituting a monophyletic group, including the Central American Amazona albifrons, while further revealing a paraphyletic history for the extant Amazon species of the Lesser Antilles. The reconstructed phylogeny provides further insights into the mainland sources of the Antillean Amazona, reveals areas of taxonomic uncertainty within the genus, and presents historical information that may be included in conservation priority-setting for Amazon parrots.
亚马逊鹦鹉（Amazona属）是所有鸟类中最容易辨认且濒危的鸟类之一。利用来自六个分区（包括线粒体区域COI、12S和16S以及核区域β - fibint7、RP40和TROP）的DNA序列数据进行系统发育综合分析，研究了关于亚马逊鹦鹉进化历史的几种假说。结果表明，如最初所暗示的那样，就黄脸鹦鹉（Amazona xanthops）的位置而言，亚马逊鹦鹉并非单系群。此外，该分析证实了先前的研究，即新热带短尾鹦鹉属是亚马逊鹦鹉的姐妹群。在更精细的层面上，系统发育将大安的列斯群岛特有物种解析为一个单系群，包括中美洲的白额亚马逊鹦鹉（Amazona albifrons），同时进一步揭示了小安的列斯群岛现存亚马逊鹦鹉物种的并系历史。重建的系统发育为安的列斯群岛亚马逊鹦鹉的大陆来源提供了进一步的见解，揭示了该属内分类学不确定的领域，并提供了可能纳入亚马逊鹦鹉保护优先级设定的历史信息。
