This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).Migration is a fundamental characteristic of the life history of many organisms allowing individuals to take advantage of different habitats as environments change seasonally. For example, over two-thirds of all landbirds that breed in temperate North America fly thousands of kilometers to nonbreeding areas in Central and South America. Traveling long distances is energetically expensive, and the mortality associated with migration is thought to be substantial. How well a bird solves problems that arise during migration determines the success of migration, and ultimately a bird's survival. That said, following individuals throughout the year poses a serious challenge, and our understanding of the behavior of migrating birds has been constrained by not knowing the bird's breeding destination, not to mention the point of departure. Information from stable isotopes, genetic markers, and plumage coloration is integrated to geographically link individual birds captured at stopover sites in the southern U.S. during spring migration with their ultimate breeding destination in North America. This novel approach will allow a more comprehensive understanding of the strategies used by birds during migration. For example, do birds 'late' on their migration stop over for a shorter time and do they redeposit critical energy stores faster than migrants on schedule? Do late migrants 'catch up' by migrating faster or for more hours once aloft? This project will enhance not only understanding of the behavior, ecology, and evolution of migratory birds, but also development of conservation strategies for animals whose annual cycle bridges continents. The project continues a long history of undergraduate and graduate student traineeship and, because of the dramatic nature of animal migration, provides rich opportunities for outreach to educational groups and the community.

该奖项根据 2009 年《美国复苏和再投资法案》（公法 111-5）提供资金。迁徙是许多生物体生命史的基本特征，允许个体在环境季节性变化时利用不同的栖息地。例如，在北美洲温带繁殖的陆地鸟类中，有超过三分之二会飞行数千公里到达中美洲和南美洲的非繁殖地区。 长途旅行需要耗费大量精力，而且与迁徙相关的死亡率被认为很高。 鸟类解决迁徙过程中出现的问题的能力决定了迁徙的成功，并最终决定了鸟类的生存。 也就是说，全年跟踪个体是一个严峻的挑战，我们对候鸟行为的理解因不知道候鸟的繁殖目的地而受到限制，更不用说出发点了。 来自稳定同位素、遗传标记和羽毛颜色的信息被整合起来，以在地理上将春季迁徙期间在美国南部中途停留地捕获的个体鸟类与其在北美的最终繁殖目的地联系起来。 这种新颖的方法将使人们更全面地了解鸟类在迁徙过程中使用的策略。 例如，鸟类在迁徙中“迟到”的停留时间是否会较短，它们是否会比按时迁徙的迁徙者更快地重新储存关键的能量？ 迟到的迁徙者是否会通过更快地迁徙或在高空停留更长的时间来“迎头赶上”？ 该项目不仅将增进对候鸟行为、生态和进化的了解，还将为每年循环跨越大陆的动物制定保护策略。该项目延续了本科生和研究生实习的悠​​久历史，并且由于动物迁徙的戏剧性，为教育团体和社区提供了丰富的外展机会。
