A grant has been awarded to Dr. Scott Lanyon and Dr. Keith Barker at the University of Minnesota, Dr. Kevin Burns at San Diego State University, Dr. John Klicka at the University of Nevada-Las Vegas, and Dr. Irby Lovette at Cornell University to examine DNA sequences from over 800 bird species. These species (including blackbirds, tanagers, warblers, and sparrows) are among the best studied birds in the world and yet evolutionary relationships within this group remain controversial or in some cases completely unknown. The investigators will examine DNA sequence data from nearly all of the 824 species in this diverse group which represents nearly one-tenth of modern bird species. The resulting piece of the tree-of-life will provide information that will be essential to future studies of the morphologies, behaviors, and distributions of western hemisphere songbirds. This increase in our knowledge of the origins of bird diversity will also be of importance to general studies of the biodiversity of the western hemisphere. Species in this group of birds are ecologically and economically important, and understanding the group's history will stimulate and inform future research and management. This group includes everything from important crop pests to critically endangered species. Furthermore, these birds represent a huge percentage of the diversity enjoyed by everyone from backyard feeder enthusiasts to serious birders. Birding is one of the fastest growing leisure-time activities in the United States with 70.4 million participants and in excess of $14 billion dollars in related expenditures annually. This project, focused as it is on many of the most common and easily observed bird species in the US, represents an ideal opportunity to engage the public in a discussion about the Tree of Life. The participating institutions will generate such discussions through their existing education programs that communicate the importance and relevance of current research to the community at large.

明尼苏达州大学的斯科特·兰蒙（Scott Lanyon）博士和基思·巴克（Keith Barker）博士，圣地亚哥州立大学的凯文·伯恩斯（Kevin Burns），内华达州拉斯维加斯大学的约翰·克里卡（John Klicka）博士以及康奈尔大学（Cornell University）的Irby Lovette博士检查了800多种鸟类的DNA序列。 这些物种（包括黑鸟，制剂，鸣鸟和麻雀）是世界上研究良好的鸟类之一，但该组中的进化关系仍然有争议，或者在某些情况下完全未知。 研究人员将检查来自这个多样化群体中几乎所有824种的DNA序列数据，该数据代表了现代鸟类的十分之一。 生命之树的最终部分将提供信息，这些信息对于对西半球鸣禽的形态，行为和分布的未来研究至关重要。 我们对鸟类多样性起源的了解的增加对于西半球的生物多样性的一般研究也很重要。 这组鸟类的物种在生态和经济上都很重要，了解该群体的历史将刺激并为未来的研究和管理提供信息。 该小组包括从重要的农作物害虫到严重濒危物种。 此外，这些鸟代表了从后院喂食器爱好者到认真的观鸟者所享受的多样性的很大一部分。 观鸟是美国增长最快的休闲时间活动之一，参与者为7040万，相关支出超过140亿美元。 这个项目集中在美国的许多最常见，最容易观察到的鸟类上，这是一个理想的机会，可以让公众参与有关生命之树的讨论。 参与的机构将通过其现有的教育计划进行此类讨论，以传达当前研究与整个社区的重要性和相关性。
