Abstract

Avian migration has been studied for a long time. Yet, very little is understood about the mechanisms underlying the preparation and departure of these migrants twice-a-year towards their destination. In recent years, some experimental evidence is accumulated from studies on the Palearctic-Indian migratory blackheaded buntings Emberiza melanocephala and redheaded buntings Emberiza bruniceps. These are obligate latitudinal migrant passerines, with yearly to-and-fro migrations between breeding grounds in west Asia/southeast Europe and overwintering areas in India. The migratory voyages are not isolated seasonal events; rather, they are part of the overall annual itinerary closely coupled to the reproduction. This review focuses mainly on the studies that have been carried out for more than four decades on these two buntings. We will outline first the characteristic traits of the anticipation, preparation, beginning and maintaining the migratory flight. The subsequent sections summarize briefly the molecular mechanisms underlying fat fuel accumulation, and changes associated with the phasing of the activity and rest periods within 24-h day during the nocturnal flight and daytime stopovers. In addition, we discuss mechanistic differences between the onward (to wintering areas, autumn migration) and return (to breeding grounds, spring migration) migrations. The two seasonal migrations differ in the context, physiological states that birds are in prior to each migration, and surrounding physical environment (photoperiod, temperature, food availability) that birds encounter during the migration period. The final section on perspectives presents an ecological and societal relevance of avian migration research.

了解古北印度迁徙猎鸟迁徙表型的复杂性:从实验室研究中连接分子点
鸟类迁徙的研究已经进行了很长时间。然而,人们对这些移徙者每年两次准备和离开目的地的机制了解甚少。近年来,对古北印度迁徙黑头猎Emberiza melanocephala和红头猎Emberiza bruniceps的研究积累了一些实验证据。它们是专向纬度迁徙的雀鸟,每年在西亚/东南欧的繁殖地和印度的越冬区之间来回迁徙。迁徙航行不是孤立的季节性事件;相反,它们是与繁殖密切相关的整个年度行程的一部分。这篇综述主要集中在四十多年来对这两种狩猎进行的研究。我们将首先概述候鸟的预期、准备、开始和保持候鸟的特征。接下来的章节简要总结了脂肪燃料积累的分子机制,以及与夜间飞行和日间停留期间24小时内活动和休息时间的分阶段相关的变化。此外,我们还讨论了向前(到越冬地区,秋季迁徙)和返回(到繁殖地,春季迁徙)迁徙之间的机制差异。这两种季节性迁徙的不同之处在于它们在迁徙前的生理状态和周围的物理环境(光周期、温度、食物供应)。最后一节介绍了鸟类迁徙研究的生态和社会相关性。
