Revised evolutionary and taxonomic synthesis for parrots (order: Psittaciformes) guided by phylogenomic analysis

Parrots (Order: Psittaciformes) are a diverse clade that are easily distinguishable from other birds. Despite the clear characters that define the Psittaciformes (hooked bills, zygodactylous feet, and plumage that is often predominantly green or red), relative morphological uniformity among parrots has made taxonomic classification a fraught endeavor for over a century. Parrot systematics were propelled forward when DNA sequencing data shed insights into higher- and species-level relationships. However, despite these significant advances, major gaps in taxon sampling and uncertainty in relationships remained due to inferring phylogenetic relationships with short fragments of DNA. Recent work using genome-wide molecular markers with nearly complete parrot species-level sampling has brought clarity to many of the remaining outstanding questions on taxonomic relationships. Here, we build on this work by including four additional species to present a taxonomic revision of Psittaciformes bet...,

鹦鹉类（鹦形目Psittaciformes）是一类多样性丰富的演化支，可轻易与其他鸟类区分开来。尽管鹦形目拥有明确的鉴别特征——钩状喙、对趾足，以及通常以绿色或红色为主的羽色——但鹦鹉类相对统一的形态特征，使得其分类学研究在过去一个多世纪以来始终是一项棘手的工作。当DNA测序数据为高级阶元与物种级亲缘关系研究提供新视角时，鹦鹉分类学得到了长足推进。然而，尽管取得了这些重要进展，由于仅基于短片段DNA推导系统发育关系，类群采样的重大缺失与亲缘关系的不确定性问题依然存在。近期，依托全基因组分子标记并完成近乎全面的鹦鹉物种级采样的研究，为诸多悬而未决的分类学亲缘关系问题带来了清晰的解答。本研究在此前工作的基础上，新增4个物种，对鹦形目开展分类学修订……详见正文方法部分。
