Birds are adapted to light through a variety of mechanisms. They have specialized retina cells that enhance vision in different lighting conditions. Migratory birds can sense Earth's magnetic field, aided by light-sensitive proteins called cryptochromes. Increased daylight can trigger breeding behaviors, while some species adjust their daily activities to the light cycle, optimizing foraging and predator avoidance. This combination of physical and behavioral adaptations ensures they thrive in diverse environments.
