我们对鸟类生命树的了解仍然不确定，特别是在更深层次上，因为它们在进化历史的早期迅速多样化。它们是地球上数量最多的陆地脊椎动物，对系统学家来说具有巨大的历史意义。鸟类在经济和生态上也很重要，因此受到了深入的研究，尽管它们对人类很重要并且很有趣，但目前大约 13% 的类群可能由于人类活动而被列入濒危物种名单。尽管如此，目前还不存在包括灭绝和现存物种的全面系统发育。在这里，我们提出了一个物种级超级树，使用简约方法的矩阵表示构建，包含来自近 1000 个来源系统发育的所有物种的大约三分之二，具有广泛的分类覆盖范围。树的源数据是根据严格的协议收集和处理的，以确保数据处理的稳健和准确。由此产生的树拓扑结构在很大程度上与鸟类系统发育的分子假设一致。我们确定了与当前鸟类系统学观点广泛一致的领域以及需要进一步工作的领域。我们还强调需要基于叶子的支持措施，以识别超级树中的流氓类群。这是对灭绝和现存鸟类超级树的首次尝试，它并不是为了对鸟类系统学进行彻底改革或作为分类学重新分类的基础，而是为宏观进化、保护、生物多样性、比较生物学和特征进化的进一步研究提供了坚实的基础，特别是化石的包含将允许研究鸟类在整个深时期的进化和多样化。
Our knowledge of the avian tree of life remains uncertain, particularly at deeper levels due to the rapid diversification early in their evolutionary history. They are the most abundant land vertebrate on the planet and have been of great historical interest to systematists. Birds are also economically and ecologically important and as a result are intensively studied, yet despite their importance and interest to humans around 13% of taxa currently on the endangered species list perhaps as a result of human activity. Despite all this no comprehensive phylogeny that includes both extinct and extant species currently exists. Here we present a species-level supertree, constructed using the Matrix Representation with Parsimony method, of Aves containing approximately two thirds of all species from nearly 1000 source phylogenies with a broad taxonomic coverage. The source data for the tree were collected and processed according to a strict protocol to ensure robust and accurate data handling. The resulting tree topology is largely consistent with molecular hypotheses of avian phylogeny. We identify areas that are in broad agreement with current views on avian systematics and also those that require further work. We also highlight the need for leaf-based support measures to enable the identification of rogue taxa in supertrees. This is a first attempt at a supertree of both extinct and extant birds, it is not intended to be utilised in an overhaul of avian systematics or as a basis for taxonomic re-classification but provides a strong basis on which to base further studies on macroevolution, conservation, biodiversity, comparative biology and character evolution, in particular the inclusion of fossils will allow the study of bird evolution and diversification throughout deep time.
