Birds see much more contrast in a green environment such as forests than we do
Seeing the world through a bird’s eye - life short science news

While the human eye use the primary colors red, green and blue for color vision, birds use in addition a fourth color, invisible to the human eye : ultraviolet.

With the aid of a special camera and advanced calculations, biologists have been able to figure out what the world looks like through the eyes of birds. It appears that birds perceive the upper sides of leaves much lighter than we do, and from below the leaves appear very dark.

This enhances contrast dramatically, so that birds can navigate and forage easily in forests, and do not see the forest as a uniform green wall as we do.
