Abstract
Light is a crucial environmental factor influencing circadian rhythms and photoperiodism in birds.
- Birds exhibit seasonal breeding behaviors that are closely linked to changes in light exposure.
- The eyes, pineal organ, and hypothalamus contribute to the photoreception and organization of circadian rhythms.
- These components work together as part of a complex system involving multiple light receptors and biological clocks in birds.
