Question

Who can see more colours, humans or birds?

Answer 1

Birds can see more colours than humans. Birds have four types of cone cells in their eyes, compared to the three types found in humans. This allows them to see a wider range of colours, including ultraviolet light, which humans cannot see.

Answer 2

Birds can see more colors than humans. While humans have three types of color receptors (red, green, and blue cones), birds have four or five types of color receptors, which allow them to perceive a greater range of wavelengths of light. This results in birds being able to see ultraviolet colors and a wider range of hues than humans can. Additionally, some birds, like eagles and hawks, have sharp visual acuity that allows them to detect tiny movements from miles away.
