Non-technical Summary Ecological factors have a variety of effects on the behavior of organisms. However, relatively little is known in detail about how these factors translate into different behavioral decisions. This study will address ecological and social variables affecting behavioral decisions during reproduction in a seldom-studied migratory songbird, the yellow-breasted chat. A combination of radiotelemetry, molecular genetics, behavioral observation and field experiments will be used to follow the movements, mating patterns, and behavioral choices of both males and females. Additionally ecological variables (vegetation density and food abundance) will be measured. This study will assess the often cryptic movements of chats (particularly females), offspring paternity, behavior of each sex in relation to the other, and the consequences for the reproductive success of individuals. This study has several scientifically important features. First, it will test general processes, proposed in more theoretical literature, shaping male/female interactions. Second, it will provide a more detailed understanding of the effect of ecological factors on breeding behavior. These features will offer valuable insight into the potential problems faced by a little-known migratory songbird and also uncover some of the ways in which these problems are overcome. Finally, this project will enhance the training of promising graduate and undergraduate students.

非技术摘要生态因素对生物的行为有多种影响。但是，关于这些因素如何转化为不同的行为决策，详细了解相对较少的知识。这项研究将解决在很少研究的迁徙鸣禽聊天中繁殖过程中影响行为决策的生态和社会变量。将使用radiotemetry，分子遗传学，行为观察和现场实验的组合来遵循男性和女性的运动，交配模式和行为选择。另外，将测量生态变量（植被密度和食物丰度）。这项研究将评估聊天（尤其是女性），后代亲子鉴定，每种性别相对于对方的行为以及对个人生殖成功的后果的经常神秘运动。 这项研究具有几个科学重要的特征。 首先，它将测试更多理论文献中提出的一般过程，从而塑造男性/女性的相互作用。其次，它将对生态因素对繁殖行为的影响提供更详细的理解。这些功能将对鲜为人知的迁徙鸣禽所面临的潜在问题提供宝贵的见解，并发现克服这些问题的一些方式。最后，该项目将增强有前途的毕业生和本科生的培训。
