While many birds migrate to warmer climates during the winter, some species are able to stay and survive cold winters despite their small bodies and need to maintain high body temperatures. Small birds that stay in temperate latitudes during the winter have physiological adaptations to promote heat production and maintain body temperature, as well as behavioral adaptations such as social foraging in flocks that can be composed of single or multiple species. In these flocks, the network of social relationships between individuals—within and between species—affect daily foraging patterns. Thus, these physiological and behavioral adaptations are linked through a feedback loop: social foraging allows birds to collect enough food to fuel heat production, and energy expended for heat creates demand for more food, which affects social foraging dynamics. This project explores these connections between the physiology of an individual and the ecological and social relationships that arise between group members and across species when they flock together in search of scarce resources. To understand how feedback between physiology and behavior influences the social dynamics between individuals and species in a community of wintering songbirds, we will: (1) quantify the effects of physiological variation on social network stability in the face of variable ambient temperatures; (2) experimentally manipulate energetic demand among social partners to test the importance of physiological constraints on social relationships; and, (3) experimentally manipulate coordination of foraging activities among social partners to test the importance of social relationships on physiological performance. These aims will be achieved by characterizing social foraging networks and assaying physiological performance in wild, marked populations of songbirds using arrays of feeders equipped with radio-frequency identification receivers to record social foraging bouts. We will additionally tease apart reciprocal relationships between physiology and social behavior by altering both the thermal environment and resource availability in the wild. Together this work will advance our understanding of the feedback between individual phenotypic variation and community social dynamics. This project will focus on broader impacts activities in four main areas: (1) Improving training and inclusivity in STEM through research experience for undergraduates, baccalaureate students, and graduate students across two universities, (2) Improving undergraduate STEM education through integration of course-based undergraduate research experiences, (3) Improving middle school STEM education through the production of scalable, high-production, interdisciplinary lesson plans for grades 6-9 that meet U.S. Next Generation Science Standards, and (4) Public engagement through field activities and presentations.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

虽然许多鸟类在冬季迁移到温暖的气候，但有些物种尽管身体小，但仍能保持寒冷的冬季，并且需要保持高体温。在冬季，在温度纬度保持温度的小鸟具有身体适应性，可以促进热量产生和维持体温，以及行为适应，例如可以由单个或多种物种组成的羊群中的社交觅食。在这些羊群中，个人之间的社会关系网络（与物种之间）影响了日常觅食模式。这就是通过反馈循环联系起来的这些生理和行为适应：社会觅食使鸟类可以收集足够的食物来促进热量产生，而探索热量的能量会产生更多食物的需求，这会影响社会觅食动态。该项目探讨了个人的生理学与小组成员之间与物种之间出现的生态和社会关系之间的联系，当它们聚集在一起寻找稀缺资源时。要了解生理和行为之间的反馈如何影响越冬鸟社区中个人与物种之间的社会动态，我们将：（1）面对可变的环境温度，量化生理变化对社交网络稳定性的影响； （2）通过实验操纵社会伙伴之间的能源需求，以测试生理限制对社会关系的重要性； （3）通过实验操纵社会伴侣之间的觅食活动的协调，以测试社会关系对身体绩效的重要性。这些目标将通过表征社会觅食网络并使用配备有射频识别接收器的喂食器来记录社交觅食bouts的媒体阵列来实现这些目标。我们还将通过改变野外的热环境和资源可用性来嘲笑生理和社会行为之间的相互关系。这项工作将共同提高我们对个人表型变化与社区社会动态之间的反馈的理解。 This project will focus on broader impacts activities in four main areas: (1) Improve training and inclusivity in STEM through research experience for undergraduates, baccalaureate students, and graduate students across two universities, (2) Improved undergraduate STEM education through integration of course-based undergraduate research experiences, (3) Improved middle school STEM education through the production of scalable, high-production, interdisciplinary lesson plans for grades 6-9 that meet U.S. Next Generation Science标准，以及（4）通过现场活动和演示文稿的公众参与。该奖项反映了NSF的法定任务，并被认为是通过基金会的知识分子优点和更广泛影响的评论标准来评估值得支持的。
