Research on the hormonal basis of sexual differentiation of mammalian behavior and its neural substrates constitutes an important chapter in the study of neural development that has led to important insights into how to conceptualize sexuality. Here research on sexual differentiation of avian social behavior is discussed with an eye toward potential insights into avian sexuality. Hormone manipulation experiments with Japanese quail (Coturnix japonica) and zebra finches (Taeniopygia guttata) reveal dissociations between different components of sexual and social behavior. None of the components of the male behavioral phenotype appear to be organized by androgens. Avian sexuality arises from multiple processes and pathways that appear to differ for mating behavior, sexual partner preference, and pairing. This provides the mechanistic bases for changes in social behavior in the course of avian evolution.
对哺乳动物行为性别分化的激素基础及其神经基质的研究，构成了神经发育研究中的重要一章，这为如何概念化性行为带来了重要见解。本文将探讨鸟类社会行为性别分化的研究，以期对鸟类性行为有潜在的深入理解。对日本鹌鹑（Coturnix japonica）和斑胸草雀（Taeniopygia guttata）进行的激素操纵实验揭示了性行为和社会行为不同组成部分之间的分离。雄性行为表型的任何组成部分似乎都不是由雄激素组织的。鸟类性行为源于多个过程和途径，这些过程和途径在交配行为、性伴侣偏好和配对方面似乎有所不同。这为鸟类进化过程中社会行为的变化提供了机制基础。
