what type of light can birds see but humans can’t?

Birds have the ability to see ultraviolet (UV) light, which is invisible to the human eye. This means that birds can perceive colors and patterns in the UV spectrum that are completely undetectable to humans. UV light is present in sunlight and is also emitted by certain plants, flowers, and insects. It plays a crucial role in bird behavior, navigation, and mate selection.
The ability to see UV light allows birds to locate food sources, detect predators, and navigate their environment more effectively. For example, some flowers have patterns and markings in the UV spectrum that guide birds towards nectar. Certain bird feathers also reflect UV light, which can enhance their visual displays during courtship rituals.
Scientists have discovered that birds have specialized photoreceptor cells in their eyes called “double cones” that are sensitive to UV light. These double cones contain pigments that enable the detection and interpretation of UV light. In contrast, humans have only two types of color-sensitive cones in their eyes, which limits our vision to the visible light spectrum.
Overall, the ability of birds to see UV light provides them with a unique visual advantage in their natural habitats and influences various aspects of their behavior and survival.
