鸟类通常不因情感表达而受到赞赏，而当它们受到赞赏时，焦点通常集中在消极状态；然而，声音行为被认为是个人情绪状态的直接反映。鉴于超过 4000 种鸣禽会发出习得的、复杂的、针对特定环境的发声，我们认为鸣禽明显地传播着独特的积极情绪状态，并且听到歌曲也可以诱发其他鸟类的积极状态。研究表明，出于性动机而发出的歌曲反映了一种预期寻求奖励（即寻求配偶）的情绪状态，而在交配环境之外，群居群体中的歌曲则反映了一种内在奖励的状态。研究还表明，听到歌曲会引发积极的预期和奖励状态。这篇综述汇集了许多研究，这些研究强调了鸣禽伏隔核的潜在重要作用，该区域几乎是哺乳动物奖励的代名词，在积极的情绪状态中是歌唱行为和对歌曲的反应的基础。有人提出，伏隔核是进化上保守的电路的一部分，它有助于依赖于上下文的积极情绪状态，从而激励和奖励歌唱行为和对歌曲的反应。基本情绪背后的神经机制在脊椎动物中似乎是保守且相似的。因此，这些在鸣禽身上的发现有可能为干预措施提供见解，这些干预措施可以恢复因人类心理健康障碍而中断的积极的社会互动。
Birds are not commonly admired for emotional expression, and when they are, the focus is typically on negative states; yet vocal behavior is considered a direct reflection of an individual’s emotional state. Given that over 4000 species of songbird produce learned, complex, context-specific vocalizations, we make the case that songbirds are conspicuously broadcasting distinct positive emotional states and that hearing songs can also induce positive states in other birds. Studies are reviewed that demonstrate that that the production of sexually motivated song reflects an emotional state of anticipatory reward-seeking (i.e., mate-seeking), while outside the mating context song in gregarious flocks reflects a state of intrinsic reward. Studies are also reviewed that demonstrate that hearing song induces states of positive anticipation and reward. This review brings together numerous studies that highlight a potentially important role for the songbird nucleus accumbens, a region nearly synonymous with reward in mammals, in positive emotional states that underlie singing behavior and responses to song. It is proposed that the nucleus accumbens is part of an evolutionarily conserved circuitry that contributes context-dependently to positive emotional states that motivate and reward singing behavior and responses to song. Neural mechanisms that underlie basic emotions appear to be conserved and similar across vertebrates. Thus, these findings in songbirds have the potential to provide insights into interventions that can restore positive social interactions disrupted by mental health disorders in humans.
