鸟类迁徙被认为是一种独特的动物行为，在不同类群之间迁徙行为的各种表型表达中具有深刻而强烈的同源性。这里的证据存在什么可以被称为“迁徙综合征”，一个紧密结合的，古老的一组适应性特征，使鸟类致力于高度有组织的季节性迁徙，进行评估。首先列出了候鸟所面临的问题，并讨论了候鸟为应对这些问题而进化的特征。然后讨论了比较方法的有用性，以调查哪些特征是移民所独有的。一个临时的结论，也许除了夜间罗盘定位的能力，很少有证据表明，根深蒂固的共同适应的性状复合体，可以弥补这样的迁移综合征，建议。建议对迁移潜在适应的遗传和生理结构进行详细分析，并结合比较方法进一步确定不同迁移适应性状进化的系统发育水平。
Bird migration has been assumed, mostly implicitly, to represent a distinct class of animal behavior, with deep and strong homologies in the various phenotypic expressions of migratory behavior between different taxa. Here the evidence for the existence of what could be called a "migratory syndrome," a tightly integrated, old group of adaptive traits that enables birds to commit themselves to highly organized seasonal migrations, is assessed. A list of problems faced by migratory birds is listed first and the traits that migratory birds have evolved to deal with these problems are discussed. The usefulness of comparative approaches to investigate which traits are unique to migrants is then discussed. A provisional conclusion that, perhaps apart from a capacity for night-time compass orientation, there is little evidence for deeply rooted co-adapted trait complexes that could make up such a migratory syndrome, is suggested. Detailed analyses of the genetic and physiological architecture of potential adaptations to migration, combined with a comparative approach to further identify the phylogenetic levels at which different adaptive traits for migration have evolved, are recommended.
