The presence of coyotes is not uncommon in North America. These nocturnal animals can frequently be seen searching for food in the early morning or late evening hours when they are most active in the environment. Even though they have amazing vision, there is one color of light—specifically red—that they are unable to see.
Why Coyotes Can’t See Red Light
- One of the reasons why coyotes cannot see red light is that their eyes lack cones that are sensitive to long wavelengths of light. Cones are responsible for color vision; without them, an animal would only be able to see in shades of gray. Studies have shown that rods, which are responsible for night vision, are more sensitive to green and blue light than they are to red light.
- Another reason why coyotes cannot see red light is that their eyes have a reflective layer known as the tapetum lucidum. This layer reflects incoming light back through the retina a second time, which increases the amount of light that reaches the photoreceptors and improves night vision.
However, this reflective layer only works with short wavelengths of light; since red light has a longer wavelength, it cannot be reflected back through the retina. - The third and final reason why coyotes cannot see red light has to do with something called retinal pigment migration. This is a process that occurs over the course of an animal’s lifetime; as an animal gets older, its photoreceptors gradually migrate from the outer edge of the retina to the center. Since red light is less visible than other colors of light at the edge of the retina, animals that undergo this process will eventually lose their ability to see red light entirely.

What color light can coyotes not see and why is this important to know for homeowners and pet owners alike
Because it stands out to them, coyotes are drawn to the color green when they see it. Because of its incredible brilliance, green light can be mistaken for white light. Red lights, on the other hand, are significantly more difficult for coyotes to detect.

Homeowners and those who own pets can assist decrease the likelihood of a coyote entering their property by utilizing a red light at dusk and dawn.

Some tips on how to live with coyotes if you already have them in your neighborhood
Coyotes are a common sight in many urban and suburban areas, and while they generally avoid contact with humans, there are a few things you can do to minimize the chances of conflict.
Firstly, never feed coyotes or leave food out that might attract them.
Secondly, keep your pets safe by keeping them on a leash or contained in a fenced area. If you do encounter a coyote, avoid running away; instead, make loud noises and try to scare it off. Repellents or fencing may also help to discourage coyotes from entering your property. Remember, however, that coyotes are wild animals and should not be treated as pets.
If you see a coyote that is acting aggressively or fearlessly towards humans, report it to the authorities immediately.
By following these simple tips, you can help to reduce the chances of an encounter with a coyote turning into a dangerous situation.

Conclusion
While coyotes have excellent eyesight overall, there is one color of light that they cannot see: red. This is because their eyes lack cones that are sensitive to long wavelengths of sound, they have a reflective layer that only works with short wavelengths of sound, and because of something called retinal pigment migration.
