Many animals migrate during specific periods of the year, moving between wintering and breeding locations. Specifically this research will test the role of overwintering habitat quality in the timing of migration initiation, duration of migration and arrival at the breeding area, as well as ability of Black-and-white-warblers to compensate for the quality of the overwintering habitat while stopping at refugia to refuel during migration. This research will link the timing and distance of migration to subsequent reproductive success during the breeding period and ability to successfully survive the winter using the presence of stable isotopes in feathers and amount of plasma metabolites to quantify an individual's condition. Information about the activity at the stopover areas will allow assessment of the carry-over of nutrients and condition between breeding, migration and overwintering and the integration of all phases of the annual life history cycle. These data will enhance our understanding of how the different phases of an individual's life cycle influence each other. In addition, the project will also provide cross-disciplinary biological training for graduate and undergraduate students from underrepresented groups.

许多动物在一年中的特定时期进行迁徙，在越冬地和繁殖地之间移动。具体来说，本研究将测试越冬栖息地质量对迁徙开始时间、迁徙持续时间和到达繁殖区的作用，以及黑白莺补偿越冬栖息地质量的能力，同时迁徙过程中在避难所停下来加油。这项研究将利用羽毛中稳定同位素的存在和血浆代谢物的量来量化个体的状况，将迁徙的时间和距离与繁殖期间随后的繁殖成功以及成功越冬的能力联系起来。 有关中途停留区活动的信息将有助于评估繁殖、迁徙和越冬之间营养物质和状况的残留，以及年度生命史周期所有阶段的整合。这些数据将增强我们对个人生命周期的不同阶段如何相互影响的理解。此外，该项目还将为来自弱势群体的研究生和本科生提供跨学科的生物学培训。
