This article is part of a Special Issue "SBN 2014". Understanding affiliative behavior is critical to understanding social organisms. While affiliative behaviors are present across a wide range of taxa and contexts, much of what is known about the neuroendocrine regulation of affiliation comes from studies of pair-bond formation in prairie voles. This leaves at least three gaps in our current knowledge. First, little is known about long-term pair-bond maintenance. Second, few studies have examined non-mammalian systems, even though monogamy is much more common in birds than in mammals. Third, the influence of breeding condition on affiliation is largely unknown. The zebra finch (Taeniopygia guttata) is an excellent model system for examining the neuroendocrine regulation of affiliative behaviors, including the formation and maintenance of a long-term pair bond. Zebra finches form genetically monogamous pair bonds, which they actively maintain throughout the year. The genomic and neuroanatomical resources, combined with the wealth of knowledge on the ecology and ethology of wild zebra finches, give this model system unique advantages to study the neuroendocrine regulation of pair bonding. Here, we review the endocrinology of opportunistic breeding in zebra finches, the sex steroid profiles of breeding and non-breeding zebra finches (domesticated and wild), and the roles of sex steroids and other signaling molecules in pair-maintenance behaviors in the zebra finch and other monogamous species. Studies of zebra finches and other songbirds will be useful for broadly understanding the neuroendocrine regulation of affiliative behaviors, including pair bonding and monogamy.
本文是“2014年社会行为神经科学网络（SBN）”特刊的一部分。理解亲和行为对于理解社会性生物至关重要。虽然亲和行为在广泛的分类群和情境中都存在，但目前关于亲和行为神经内分泌调节的许多知识都来自对草原田鼠配偶关系形成的研究。这在我们目前的知识中至少留下了三个空白。第一，对于长期配偶关系的维持知之甚少。第二，很少有研究考察非哺乳动物系统，尽管一夫一妻制在鸟类中比在哺乳动物中更为普遍。第三，繁殖条件对亲和行为的影响在很大程度上尚不清楚。斑胸草雀（Taeniopygia guttata）是研究亲和行为神经内分泌调节的优秀模型系统，包括长期配偶关系的形成和维持。斑胸草雀形成基因上一夫一妻制的配偶关系，并全年积极维持。基因组和神经解剖学资源，再加上关于野生斑胸草雀生态学和行为学的丰富知识，使这个模型系统在研究配偶关系的神经内分泌调节方面具有独特优势。在这里，我们综述了斑胸草雀机会性繁殖的内分泌学、繁殖和非繁殖斑胸草雀（家养和野生）的性类固醇谱，以及性类固醇和其他信号分子在斑胸草雀和其他一夫一妻制物种配偶维持行为中的作用。对斑胸草雀和其他鸣禽的研究将有助于广泛理解亲和行为的神经内分泌调节，包括配偶关系和一夫一妻制。
