Approximately two-thirds of all songbird species that breed in eastern North America migrate to tropical areas for the winter, requiring most species to cross the Gulf of Mexico. Flights across the gulf are considered hazardous and may result in mass mortality. Atmospheric conditions over water, as well as characteristics of the birds themselves (e.g., age, physical condition), are likely important predictors of birds' migratory routes and survival. However, most knowledge about when, where and how small birds cross large water bodies and their survival remains speculative, because until now researchers have been unable to track individuals between the start and end points of over water flights. Anticipated changes in atmospheric structure and dynamics caused by climate change urgently require an understanding of how migrating birds interact with the atmosphere. This knowledge will provide insight to potential consequences of climate change on migratory songbirds, many of which are experiencing population declines. Knowledge of animal-atmosphere relationships is timely as wind energy development accelerates and coastal habitat alteration along migratory flyways continues. The interdisciplinary research team will combine modern radio telemetry and favorable geography to document migratory flights of songbirds across the gulf. By integrating field data, atmospheric data and computational simulations and analyses, the team will provide the first estimate of songbird survival during migration across open water. They also will study factors shaping birds' migratory routes and timing. The team will promote learning, excitement and appreciation for science, and animal migration in particular, to non-scientists through educational materials (e.g., animated migration trajectories in Google Earth©). The team will disseminate findings to scientists, reserve managers and the general public via presentations, publications, a bilingual project website, and popular media. American and Latino undergraduate and graduate students and post-doctoral researchers will participate in each phase of research to acquire learning and skill-building opportunities.

所有歌手的迁徙路线和生存中约有三分之二。但是，大多数关于小鸟何时，何时和如何穿越大水体及其生存的知识仍然是推测性的，因为到目前为止，研究人员一直无法跟踪水上飞行的起点和终点之间的个人。由于气候变化而引起的大气结构和动态的预期变化，需要了解迁移鸟与大气相互作用的理解。这些知识将洞悉气候变化对迁徙鸣禽的潜在后果，其中许多人的人口下降。随着风能发展的加速和沿迁移飞行的沿海栖息地的改变，对动物 - 大气关系的了解及时。跨学科研究团队将结合现代射电遥测和有利地理位置，以记录整个海湾歌手的迁徙飞行。通过整合现场数据，大气数据以及计算模拟和分析，该团队将在跨水域迁移期间对鸣禽存活率进行首次估计。他们还将研究塑造鸟类迁徙路线和时机的因素。该团队将通过教育材料（例如，在Google Earth中©）来促进对科学的学习，兴奋和欣赏，尤其是动物迁移的人（例如，动画迁移轨迹）。该团队将通过演讲，出版物，双语项目网站和受欢迎的媒体向科学家，储备经理和公众传播发现。美国和拉丁裔的本科生，研究生以及博士后研究人员将参加每个研究阶段，以获取学习和技能建设机会。
