The Corvides (previously referred to as the core Corvoidea) are a morphologically diverse clade of passerine birds comprising nearly 800 species. The group originated some 30 million years ago in the proto-Papuan archipelago, to the north of Australia, from where lineages have dispersed and colonized all of the world's major continental and insular landmasses (except Antarctica). During the last decade multiple species-level phylogenies have been generated for individual corvoid families and more recently the inter-familial relationships have been resolved, based on phylogenetic analyses using multiple nuclear loci. In the current study we analyse eight nuclear and four mitochondrial loci to generate a dated phylogeny for the majority of corvoid species. This phylogeny includes 667 out of 780 species (85.5%), 141 out of 143 genera (98.6%) and all 31 currently recognized families, thus providing a baseline for comprehensive macroecological, macroevolutionary and biogeographical analyses. Using this phylogeny we assess the temporal consistency of the current taxonomic classification of families and genera. By adopting an approach that enforces temporal consistency by causing the fewest possible taxonomic changes to currently recognized families and genera, we find the current familial classification to be largely temporally consistent, whereas that of genera is not.
鸦科鸟类（以前称为核心鸦总科）是雀形目鸟类中形态多样的一个分支，包含近800个物种。该类群约在3000万年前起源于澳大利亚北部的原巴布亚群岛，其谱系从那里扩散并殖民了世界上所有主要的大陆和岛屿陆地（南极洲除外）。在过去十年中，已经为各个鸦科鸟类家族生成了多个物种水平的系统发育树，最近基于使用多个核基因座的系统发育分析，家族间的关系也得到了解决。在本研究中，我们分析了八个核基因座和四个线粒体基因座，以生成大多数鸦科鸟类物种的定年系统发育树。这个系统发育树包括780个物种中的667个（85.5%）、143个属中的141个（98.6%）以及所有31个目前公认的科，从而为全面的宏观生态、宏观进化和生物地理分析提供了一个基线。利用这个系统发育树，我们评估了目前科和属的分类在时间上的一致性。通过采用一种通过对目前公认的科和属进行尽可能少的分类学变化来强制时间一致性的方法，我们发现目前的科分类在很大程度上在时间上是一致的，而属的分类则不然。
