Photoperiodism and circadian rhythms have been studied intensively in birds because Aves are typical seasonal breeders and diurnal animals. Light is the most important environmental factor involved in entrainment of circadian rhythms and photoperiodism. The eyes and the extraocular photoreceptors, such as the pineal organ and hypothalamus, are reported to have an important function not only for photoreception but also for circadian organization in nonmammalian vertebrates, including birds. In this report, we review the roles of the eyes, pineal organ, and deep brain as the components of the multiphotoreceptor and multioscillator system in avian circadian organization.
由于鸟类是典型的季节性繁殖者和昼行性动物，因此对其光周期现象和昼夜节律进行了深入研究。光是参与昼夜节律和光周期现象调节的最重要环境因素。据报道，眼睛和眼外光感受器，如松果体和下丘脑，不仅在非哺乳动物脊椎动物（包括鸟类）的光接收方面具有重要功能，而且在昼夜节律组织方面也具有重要功能。在本报告中，我们综述了眼睛、松果体和深部脑作为鸟类昼夜节律组织中多光感受器和多振荡器系统组成部分的作用。
