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.

明尼苏达大学的 Scott Lanyon 博士和 Keith Barker 博士、圣地亚哥州立大学的 Kevin Burns 博士、内华达大学拉斯维加斯分校的 John Klicka 博士和康奈尔大学的 Irby Lovette 博士获得了一笔资助，用于检查 800 多种鸟类的 DNA 序列。 这些物种（包括黑鸟、唐纳雀、莺和麻雀）是世界上研究最深入的鸟类之一，但该类群内的进化关系仍然存在争议，或者在某些情况下完全未知。 研究人员将检查这个多样化群体中几乎所有 824 个物种的 DNA 序列数据，该群体代表了现代鸟类物种的近十分之一。 由此产生的生命树片段将为未来研究西半球鸣禽的形态、行为和分布提供至关重要的信息。 我们对鸟类多样性起源的了解的增加对于西半球生物多样性的一般研究也很重要。 该鸟类群体中的物种在生态和经济上都具有重要意义，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。 该组包括从重要农作物害虫到极度濒危物种的所有物种。 此外，从后院喂食爱好者到认真的观鸟者，这些鸟类代表了每个人所享有的多样性的很大一部分。 观鸟是美国增长最快的休闲活动之一，每年有 7040 万名参与者，相关支出超过 140 亿美元。 该项目重点关注美国许多最常见、最容易观察到的鸟类，为公众参与有关生命之树的讨论提供了一个理想的机会。 参与机构将通过其现有的教育计划发起此类讨论，向整个社区传达当前研究的重要性和相关性。
