Which color is the pigeon afraid of?

There is no scientific evidence that pigeons are afraid of a specific color, as pigeons have excellent color vision and can see ultraviolet light, but they are not inherently afraid of colors like red, blue, or green. Some anecdotal claims and pest control products suggest pigeons are afraid of certain colors, but these are largely myths. For example, some people claim pigeons are afraid of white because it signals danger, or red because it resembles blood or predators, or that reflective or shiny colors scare them, but studies show pigeons quickly habituate to colors if food and shelter are available. What does deter pigeons somewhat is bright, flashing, or reflective objects that move, such as reflective tape, shiny pinwheels, or CDs hung on balconies, because the unpredictable flashes of light startle them, not the color itself. In some deterrent products, fake predator eyes in yellow and black are used to scare birds, but effectiveness is limited. Pigeons are more afraid of predator shapes like hawks and owls than colors. Some research shows birds may avoid certain colors for food, but not for fear. So there is no single color pigeons are afraid of, they are more affected by movement, predator shapes, and lack of food than by color, and using color alone will not keep pigeons away long term without removing food and sealing roosting sites.
