Understanding Bird Senses
Birds have the same five senses humans do—sight, hearing, touch, taste, and smell—but they are specialized to help birds survive. While the acuity and usefulness of a bird's exact senses depend on its species, all bird senses share certain characteristics.
Sight
Eyesight is a bird's most critical sense and the one it relies on the most for flight, evading predators and finding food. Birds have a thicker retina than humans, and their eyes are larger in proportion to their head size. They have much denser rods and cones—the "seeing" cells—packed on the retina, giving them superior vision in both black-and-white and color. The range of colors birds see is not much greater than humans, but some species, such as hummingbirds, can see ultraviolet colors.
Where birds' eyesight excels is in the perception of motion and detail. Birds can see small motions or tiny details 2-3 times better than humans, which can help them find food more easily, or see the stealthy approach of a predator. In many birds, the eyes are positioned further apart on the head, giving them a wider field of view than humans. Birds with eyes on the sides of their head, such as most songbirds, can nearly see directly behind themselves, which can be useful for detecting predators and evading attacks.
Because their vision is so critical, birds have an inner nictitating membrane that helps protect their eyes and cleans them frequently. During a fight birds often spread their wings to protect their eyes, and when attacking, they know instinctively to go for the eyes of their adversary......hiii
