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.

在北美东部繁殖的所有鸣禽物种中，大约有三分之二会迁徙到热带地区过冬，因此大多数物种需要飞越墨西哥湾，这被认为是危险的，可能会导致水面上的大量死亡。以及鸟类本身的特征（例如年龄、身体状况）可能是鸟类迁徙路线和生存的重要预测因素。然而，大多数关于小鸟类何时、何地以及如何穿越大型水体及其生存的知识仍然存在。 。这是推测性的，因为到目前为止，研究人员还无法追踪水上飞行的起点和终点之间的个体。气候变化引起的大气结构和动态的预期变化迫切需要了解候鸟如何与大气相互作用。跨学科研究小组将深入了解气候变化对迁徙鸣禽的潜在影响，其中许多候鸟正在经历种群数量下降。结合现代无线电遥测和有利的地理来记录鸣禽穿越海湾的迁徙飞行，该团队还将研究通过整合现场数据、大气数据和计算模拟和分析，对鸣鸟在开放水域迁徙过程中的生存情况进行首次估计。该团队将通过教育材料（例如 Google Earth© 中的动画迁徙轨迹）促进非科学家对科学（尤其是动物迁徙）的学习、兴趣和欣赏。通过演讲、出版物、双语项目网站和流行媒体向科学家、保护区管理人员和公众传播研究结果，美国和拉丁美洲的本科生、研究生和博士后研究人员将参与每个阶段的研究，以获得学习和技能。建设机会。
