Through studying the beak size of Galapagos finches Charles Darwin developed his fundamental idea of natural selection. These finches, and their relatives in the tanager family, continue to inform science today in a project to study why they have been successful in generating so many species. Beak size, feather color, songs, and ecological niche play important roles in the extraordinary diversification of this large American lineage that represents over 4% of bird species. This project will develop a phylogeny and a trait data matrix to compare evolutionary patterns and correlations of these traits with diversification rates. The results will determine whether the factors that drive natural selection in the Galapagos finches are the same factors driving speciation in other tanagers.This project investigates the broad question of how biodiversity is generated, which is essential information to the long term success of efforts to conserve biodiversity. This project will support the education and research training of least eight graduate and undergraduate students who will produce theses and publications. In addition, a large number of undergraduates will be involved in the production of online publications on tanagers, which will be published in six languages through Cornell University's Lab of Ornithology. This outreach will benefit researchers, wildlife biologists and conservationists. In addition, project researchers will present public lectures on this work to amateur birders, wildlife biologists, and conservationists.

通过研究加拉帕戈斯雀喙的大小，查尔斯达尔文发展了他的自然选择的基本思想。这些雀，以及它们在唐纳雀家族中的亲戚，继续在一个项目中为科学提供信息，以研究为什么它们能成功地产生这么多物种。 喙的大小、羽毛的颜色、歌声和生态位在这个美国大谱系的非凡多样化中发挥着重要作用，该谱系占鸟类物种的4%以上。该项目将开发一个进化发生和一个性状数据矩阵，以比较这些性状的进化模式和相关性与多样化率。 研究结果将决定在加拉帕戈斯群岛加拉帕戈斯雀的自然选择的驱动因素是否是在其他tanager.This项目驱动物种形成的相同因素调查的生物多样性是如何产生的，这是长期成功的努力，以保护生物多样性的重要信息的广泛问题。 该项目将支持至少8名研究生和本科生的教育和研究培训，他们将撰写论文和出版物。此外，大量本科生将参与制作关于唐纳雀的在线出版物，这些出版物将通过康奈尔大学鸟类学实验室以六种语言出版。这一推广活动将使研究人员、野生生物学家和自然资源保护者受益。此外，项目研究人员将向业余观鸟者、野生生物学家和自然资源保护主义者提供有关这项工作的公开讲座。
