Can Coyotes See IR Light?: Find out how coyotes perceive light and their visual capabilities

Coyotes are known for their sharp senses, particularly their keen sight, hearing, and smell, which help them thrive as adaptable nocturnal predators. When it comes to infrared (IR) light, especially the wavelengths produced by common night vision and trail cameras, the question is whether coyotes can detect it. Most scientific research indicates that coyotes, like many mammals, cannot see the longer IR wavelengths (typically above 850 nm) emitted by these devices. Their eyes are sensitive primarily to visible light, not to the infrared spectrum. However, coyotes may notice faint red glows from some older or cheaper infrared LEDs (around 850 nm) if the LEDs are visible to humans as a dull red glow. Higher wavelength "no-glow" infrared LEDs (940 nm) are generally undetectable to coyotes and most other wildlife.

Tips 1:

As a designer, I often consider how lighting—both visible and invisible—impacts animal behavior and outdoor environments. If you’re trying to observe coyotes or other wildlife discreetly, choosing the right lighting technology is crucial. For your home or property, integrating thoughtful lighting design with consideration for wildlife can help create a harmonious and effective outdoor landscape. If you’re planning layout updates or want to visualize how your property’s lighting affects its appearance and security, a tool like a home designer can support your design process with accuracy and ease.

FAQ

Q: Can coyotes see standard IR light used in most trail cameras?

A: Coyotes generally cannot see IR light at wavelengths above 850 nm, which is common in most trail cameras, but might detect faint red glows from some LEDs.

Q: Are “no-glow” trail cameras visible to coyotes?

A: “No-glow” trail cameras (using 940 nm LEDs) are not visible to coyotes and are ideal for undetected wildlife observation.

Q: What senses do coyotes rely on most?

A: Coyotes rely heavily on their sense of smell, hearing, and then sight for hunting and awareness.

Q: Do coyotes avoid areas with visible lights?

A: Coyotes can be cautious around areas with obvious visible lights, but IR light is almost always undetected by them.

Q: Could IR lights on security cameras deter coyotes from approaching?

A: It’s unlikely that IR lights alone deter coyotes, but visible elements (noise, movement, other lights) may make them wary.
