The objective of this project is to describe, assess, and interpret mechanisms of breeding behavior and decision-making in a natural animal population. Humans and other animals make decisions concerning where to engage in different activities and these decisions affect subsequent choices of mates, dwelling and reproductive areas, escape routes, and foraging areas. Since the "mental health", well-being, and stress levels of an organism may reflect the effectiveness of these decision-making processes, there is strong reason to believe that enlarging our pool of knowledge concerning mechanisms of decision-making about crucial life factors, such as habitat, mates, and territories will eventually contribute to clinical knowledge and treatment. Specifically, the study is based on monitoring site selection, territoriality, hormonal function, and reproductive success in a large, color-marked population of Red-winged Blackbirds. This long-term monitoring of known individuals, combined with manipulative experiments that would be impossible with humans, will provide data on how males obtain breeding territories and what information they use to maximize their chances of becoming territorial. In addition, field monitoring of plasma steroid hormone levels, especially those of testosterone and corticosterone, will reveal how hormonal states influence behavior during the breeding season and how behavior, in turn, influences circulating hormone levels. Lastly, DNA fingerprinting analysis will reveal the frequency of extra-pair fertilizations and the proportion of offspring sired by other than putative fathers, and allow us to explore the question of how strongly parent-offspring genetic relationships are correlated with mating behavior.

本项目的目标是描述、评估和解释 自然界中繁殖行为和决策的机制 动物种群。人类和其他动物会做出决定 关于在哪里从事不同的活动，以及这些 决定会影响随后对配偶、住所和 繁殖区、逃生路线和觅食区。自.以来 有机体的“心理健康”、幸福感和压力水平可能 反映这些决策过程的有效性，有 我们有充分的理由相信，扩大我们的知识库 关于关键生命的决策机制 栖息地、配偶和领地等因素最终会 有助于临床知识和治疗。 具体地说，这项研究是基于监测点的选择， 领地、荷尔蒙功能和繁殖成功 大量有颜色标记的红翼黑鸟。这 对已知个人的长期监测，结合 人类不可能进行的操纵性实验，将 提供关于雄性如何获得繁殖区域以及什么的数据 他们用来最大化他们成为 领土问题。此外，现场监测血浆类固醇 荷尔蒙水平，尤其是睾酮和 皮质酮，将揭示荷尔蒙状态如何影响行为 在繁殖季节，以及行为如何反过来影响 循环中的激素水平。最后，DNA指纹分析 将揭示额外配对受精的频率和 非假定父亲所生子女的比例；以及 允许我们探索亲子关系有多强的问题 遗传关系与交配行为相关。
