Do falcons see more colors than humans?

No, falcons do not see more colors than humans. Birds have four types of cone cells in their retinas, allowing them to perceive colors such as ultraviolet and violet, which are not visible to humans. However, humans can perceive a wider range of colors overall due to the way their cone cells overlap and send signals to the brain. While birds may be better at seeing certain colors in the ultraviolet spectrum, humans see more distinct hues and greater variation within the visible spectrum.
