As hunters, our eyesight plays a crucial part in detecting movement but understanding how deer see hunters is just as important for preparing a successful hunt. The reason we wear orange is not only for safety but because deer and other animals cannot see the color well. This article will discuss the visible spectrum and how different animals perceive it. Every animal has a different way of seeing the world.
Deer, for example, are very good at seeing at night due to their superior low-light vision. Then we have turkeys and waterfowl who can detect UV light which means they can see light ranging from 300-400 nm, humans cannot see this range. At this range, these animals may be able to see certain clothes glow.
To understand what animals can see it's important we understand the visible spectrum. Below is an image of the visible spectrum. The visible spectrum ranges from 380 to 750 nanometers (nm), with violet at the lower end (~380 nm) and red at the higher end (~750 nm). Humans can see this full range, but animals like deer (400–500 nm) see mostly blues and yellows, while turkeys (350–700 nm) can detect ultraviolet (UV) light below 400 nm.
Each species sees the world differently based on the colors and light their eyes can detect. The table below breaks down how game animals perceive their environment, including which colors they see best, their wavelength range, and key vision traits.
Species | Color Vision | Wavelength Range (nm) | Key Features |
Humans | Trichromatic (Red, Green, Blue) | 400-750 nm | Strong color perception but weaker night vision. |
Whitetail Deer | Dichromatic (Blue, Yellow) | 400-500 nm | Excellent low-light vision, poor red/green differentiation. |
Turkey | Tetrachromatic (UV, Blue, Green, Red) | 350-700nm | Can see UV light, incredible daytime vision. |
Coyote | Dichromatic (Blue, Yellow) | 430-550 nm | Poor red/green perception, superior motion detection. |
Black Bear | Same as Humans, but slightly more nearsighted | 420-580 nm | Relies on smell more than sight, moderate color vision. |
Waterfowl | Tetrachromatic (UV, Blue, Green, Red) | 300-700 nm | Detects UV light, wide field of view. |
Whitetail Deer: Low-Light Masters
🦌 How They See:
Strong night vision due to an abundance of rod cells in their eyes.
Dichromatic vision—they see blue (400 nm) and yellow (500 nm) but struggle with reds and oranges.
310° field of view, allowing them to detect motion easily.
🎯 Hunting Tip:
Avoid wearing blue clothing, as it stands out.
Move slowly—deer detect motion better than color.
Turkey: The Sharpest Eyes in the Woods
🦃 How They See:
Exceptional color vision, including UV light (below 400 nm).
Near-360° field of view due to side-placed eyes.
Can spot slightest movement and UV-reflective objects.
🎯 Hunting Tip:
Use UV-blocking sprays on your gear to prevent glowing.
Stay still—movement gives you away faster than color.
Coyotes: The Night Hunters
🐺 How They See:
Low-light specialists, excelling at detecting movement in the dark.
Dichromatic vision (blue and yellow), with poor red and green perception.
Strong motion detection, making stealth crucial.
🎯 Hunting Tip:
Blend in with shadows and natural terrain.
Minimize movement, especially when calling or decoying.
Black Bears: Strong Noses, Weaker Eyes
🐻 How They See:
Similar to humans but slightly nearsighted.
Distinguishes blue and green but struggles with reds.
Relies on scent more than sight when detecting threats.
🎯 Hunting Tip:
Wind direction is more important than camouflage—if they smell you, they’re gone.
Move slowly; their eyesight isn’t sharp, but sudden movement will alert them.
Waterfowl: The Ultimate Aerial Spotters
🦆 How They See:
Nearly 340° field of vision, allowing them to detect movement from above and below.
Tetrachromatic vision (UV, Blue, Green, Red)—more advanced than human vision.
Can see UV reflections, making them highly sensitive to unnatural light sources.
🎯 Hunting Tip:
Cover your face and hands to reduce visibility.
Avoid shiny or reflective gear, as waterfowl can see sunlight glare.
Final Thoughts
Understanding how different animals see the world gives us hunters a real advantage. Whether it’s avoiding a certain color of clothing for deer, using UV-blocking gear for turkeys, or staying still to keep from getting spotted, knowing how different animals perceive their surroundings will help your chances of having a successful hunt.
Next time you’re setting up for a hunt, think about what the animal sees, not just what you see. The better you blend in with their world, the better your chances of success.
