Here’s WHY It’s Hard As Hell To Sneak Up On A Trophy Whitetail

What, exactly are you up against when you try to get that shot?

What, exactly are you up against when you try to get that shot?

They are what’s for dinner. So they have some very good defense mechanisms. Reflexes are one, but great eyesight is another.

When you’re talking great vision for a prey animal, it looks quite a bit different than it does for a hunter.

We’re not talking about binocular vision. Their vision is set up for defense.

They’ve got a 300-degree view of their surroundings… thanks to those horizontal pupils and a trait called cyclovergence which is a fancy way of saying that the pupils can rotate along 2 different axes. It’s how those pupils can stay aligned even when their heads dip down to eat or drink.

Here’s what those eyes look like up close. Notice the pupil:

That translates into a field of vision that looks like this:

That’s a pretty respectable defensive advantage even to begin with. But there’s more.

They also have the ability to see much longer distances than people.

Unlike humans, deer don’t have an ultraviolet (UV) filter in their lens, making their eyes far more susceptible to the sun’s damaging UV rays. The trade-off is that researchers surmise deer can see UV light — something humans can’t detect.
By studying the physical characteristics of deer eyes, scientists estimate deer have 20/100 vision. This means that the level of detail whitetails see at 20 feet is what normal human vision can see back to 100 feet.
…Researchers also discovered that deer have a higher ratio of rods to cones and a pupil 10 times larger than humans. These factors, and the lack of a UV filter, give deer far superior vision in low light.

Testing shows deer see blue-wavelength light best, and red the worst. And there were a couple of other tips to keep in mind before you head out into the woods:

“It’s no coincidence that during dawn and dusk, when the greatest amount of light is in the blue spectrum, is also when deer are most active,” said Cohen. “They’re most adapted to the wavelength of light that is most available when they move around the most.”
Because deer can’t distinguish color shades as well as we can, wearing camouflage clothing containing similar colors actually makes you appear like one big blob to deer.
“While deer color vision is important, they key in more on movement,” added Cohen. “If you are a solid silhouette, movement is easier to pick up on than if you wear clothing containing colors that break up your outline.”

Happy hunting!

If a person looked to Scripture and paid particular attention to the passages within the Bible that address the topic of hunting, then they’d walk away thinking not only is hunting animals tolerated but it is endorsed by God. And that’s exactly what this little book is about: proving that God, from Genesis to Revelation, is extremely cool with hunters and hunting. I’ll go out on a biblical limb and claim right off the bat that you cannot show me, through the balance of the Bible, that the God of the Scripture is against the responsible killing and the grilling of the animals He created. ~Doug Giles
 
In his killer new book RISE, KILL & EAT: A Theology of Hunting From Genesis to Revelation Doug carries on with his courageous war against the lunatic fringe who dare recommend Bambi solutions to the annual production of edible wildlife. –Ted Nugent
