20 Deer Hunting Lies Your Granddaddy Told You

By author of Brow Tines and Backstrap

Has Anyone Ever Told You These Half-Truths and Fallacies Were Fact?

Deer hunting is a whirlpool of beliefs, theories, facts and fallacies. Some ideas are right. Some are wrong. And others fall somewhere in-between.

Now, I’m not saying your granddaddy ain’t a good deer hunter. Chances are he’s killed more deer with his open-sighted, lever-action Marlin 30-30 than all the local youngins hollerin’ “Smoked him,” “Pole-waxed that joker,” or my personal (least) favorite, “Just gave that ol’ slob a dirt nap” combined. But our past (and current) generations of deer hunters are somewhat responsible for a number of myths that deer hunters still believe today.

All joking aside, I’m sure your granddaddy is/was a great deer hunter. So was your daddy. And so are you.

That said, there’s quite a few fallacies that have floated around the deer hunting wavelengths for far too long. And it’s high-time we snuff out the false flames.

The Biggest Doe Is Always the Oldest One

1 | The Biggest Doe Is Always the Oldest One

It’s a common belief the oldest doe in the herd is also always the biggest doe. Not true. Does generally reach their peak body size/weight around the age of four or five. Older does, especially those that make it past the age of seven or eight, typically weigh less than middle-aged does.

On the flip side, it’s important to understand what you’re looking at with each given encounter. If a doe and two fawns step out, sure, the biggest one is the oldest doe. However, if six or seven antlerless deer walk into view, don’t automatically assume the biggest is the oldest. Sometimes really old does can resemble yearling and 2-year-old does. Pay close attention to other body characteristics and weight/fat distribution to see the entire picture.

Age Determines Sexual Maturity in Doe Fawns

Image 2 of 20

2 | Age Determines Sexual Maturity in Doe Fawns

Many people believe doe fawns become sexually mature once they reach a certain age. That’s false. They become sexually mature once they reach a certain weight. Different doe fawns reach that weight threshold at different ages. Factors that influence when this threshold is reached include time of birth, its mother’s effectiveness as a provider/protector, weather, available food sources and genetics.

To further illustrate this, approximately 50 percent of doe fawns in the Midwest breed their first fall and a much lower percentage do so in the Southeast. Better food and habitat allow most fawns in the Midwest to reach that weight much sooner than their southeastern cousins.

Some doe fawns will conceive. Some won’t conceive until they’re 1½ years old the following fall. Others breed somewhere in-between. But it’s different for every doe and weight is the deciding factor.

You Can Look at a Single Track and Determine if a Buck or Doe Made It

3 | You Can Look at a Single Track and Determine if a Buck or Doe Made It

Some people think they can determine the sex of the animal based on a single track. That’s lunacy. The only way to know what made a given track is to see the animal make it. There are too many variables to accurately gauge whether it’s a buck or doe based on one track alone. That said, as with most things, you can get somewhat of an idea with some additional intel. If you have multiple tracks to analyze, it is sometimes possible to guess the sex of a deer.

Bucks are wider in the front and narrower in the back. For bucks, front tracks will be noticeably farther apart than rear tracks. It’s opposite with does. They are narrower in the front and wider in the rear. Carefully analyzing a set of tracks could lead you to better understand the deer that made it. But you need more than one track to do it.

Buck-to-Doe Ratios Get Way Out of Whack

Image 4 of 20

4 | Buck-to-Doe Ratios Get Way Out of Whack

We’ve all heard that fella who thinks his buck-to-doe ratio is 1:10. But it’s virtually impossible to observe a ratio higher than 1:5, and three does per buck is even more realistic in a bad situation. Don’t be fooled by those who try to say otherwise. The data proves them wrong.

How? Kip Adams, a whitetail biologist with the Quality Deer Management Association, explains the case.

“Observed ratios are generally skewed toward does because during hunting season antlerless deer (does and fawns) are often more viewable than bucks, and many hunters inadvertently consider fawns as adult does.” Adams said. “Also, in areas of high buck harvest, the actual and observed sex ratios truly can dramatically favor does during and following the hunting season. However, this likely was not the case prior to the season.”

Still don’t believe it? There’s more.

“I often hear hunters, outdoor writers, and even biologists refer to 10:1 or 15:1 doe-to-buck ratios,” Adams continued. “These cannot be pre-hunt adult ratios because as long as the deer herd is reproducing and recruiting fawns, the ratio cannot become more skewed than about five does per buck. The biological maximum is roughly 5:1 because even in the absence of doe harvest, a certain percentage of adult does in the population will die each year from old age, vehicle collisions, disease, predators, etc. Also, about 50 percent of fawns born each year are bucks, thus the sex ratio gets an annual correction when fawns are recruited.”

In other words, don’t blame your lack of buck sightings on a bad ratio. You either just haven’t found them yet, haven’t tried hard enough, or aren’t making smart hunting decisions.

Big Bucks Have Bigger Home Ranges

Image 5 of 20

5 | Big Bucks Have Bigger Home Ranges

A lot of old timers (and younger folk) think home ranges grow as bucks age. The research actually shows that home ranges shrink as deer get older. Older bucks generally have a home range of one square mile or smaller. Yearling and 2-year-old bucks tend to have the largest home ranges.

Why is this the case? Basic needs. More dominant bucks generally inhabit the best habitat and terrain. They choose the areas where they can find food, water and cover within close proximity of one another. Traveling far and wide is frowned upon by most older members of the deer herd.

You Can Tell the Size of the Buck by the Size of the Rub

6 | You Can Tell the Size of the Buck by the Size of the Rub

It’s crazy to believe you can estimate a buck’s age/size by its rub. And the old saying that small rubs are always made by small bucks is even more so. That’s simply not true.

All of that said, small bucks typically make smaller rubs. But as for bigger deer, they make small and large rubs. The size of the tree trunk isn’t indicative of age. I’ve personally watched little bucks rub trees the size of my calf. I’ve witnessed mature bucks rub trees the size of my thumb. There are no black and white guidelines for buck rubs.

There are things you can look for that will hint at the size of the buck, though. Pay more attention to the height of the rub than the circumference of it. Older bucks are taller and rub higher up on trees than younger deer. Also look at other trees and limbs adjacent to the rub. Bucks with significant spreads will brush against nearby trees, saplings and limbs while making the primary rub. And yes, the size of the trunk can, in some instances, provide a feel for the size of the deer. The best guideline on this topic — little bucks generally make small rubs, but big bucks make big and small rubs.

The Dominant Bucks Breed All of the Does

7 | The Dominant Bucks Breed All of the Does

People think that just because a big buck is in the area that it breeds all of the does. And the majority of hunters used to believe that. Well, science tells us it isn’t so. As revealed by Kip Adams in a recent QDMA report, dominant bucks don’t breed all of the does.

“Biologists used to think large mature bucks dominated the breeding in deer herds similar to the way bull elk do,” Adams said. “The idea was the largest individuals successfully defended all receptive does (does that are in estrous and ready to breed) from other would-be suitors. This idea seemed plausible, and it wasn’t until the advent of genetic testing that paternity assessments could be done. Research during the past few years has revealed a much different picture of what actually happens in the whitetail’s breeding world.”

White-tailed bucks will spend anywhere from a day to a day and a half with an estrous doe. And oftentimes multiple does in a given area enter estrous around the same time. Furthermore, dominant bucks don’t always find estrous does right when they enter estrous. Because of these reasons and more, younger bucks comprise a significant percentage of the breeding.

Adams also stated that recent research — conducted by Dr. Randy DeYoung — shows that in areas with good age structures, bucks aged 3½ years old and older sired between 70 and 85 percent of the fawns. That means 25 to 30 percent of fawns were sired by young bucks in areas with plenty of mature bucks. Imagine how that number would increase where older bucks are far less common.

Big Bucks Always Sire Big Bucks

Image 8 of 20

8 | Big Bucks Always Sire Big Bucks

A lot of hunters falsely believe that big bucks always produce fawns that will produce big racks. It’s also a common misconception that bucks influence their offspring more than does do. Neither are true. Bucks and does contribute approximately 50 percent of the genetic makeup of a fawn. Antler characteristics can be influenced by either one.

Beyond that, the doe will raise the fawn. She’ll nurse, nourish, and raise it up to maturity. If for some reason that fawn has a hard life (late-born, the doe lacks milk production, the mother places it in low-quality cover, etc.), it’s the doe’s fault. The research shows fawns that have a hard life produce subpar antlers as yearlings and that outcome tends to carry over in the life of that buck each year afterward. Because of this the doe plays a greater roll in antler production than bucks do. And big bucks don’t always sire more big bucks.

It isn't legal to do anyway. But if it was, you couldn't turn out a world-class buck and significantly change your herd with a bunch of world class fawns. It just doesn't work that way.

The old saying is that a spike will always be a spike is a non-truth. That’s long been debunked. Studies have shown that spikes often develop very respectable racks in their prime. However, on average, they do tend to produce four to five fewer inches of antler each year than bucks that produced four or more points with their first set of antlers.

Bumped Bucks Leave the Country

Numerous studies out there show that bucks don’t do this. The research is showing that bucks are actually very loyal to their home ranges, and especially so to their core areas (the smaller 40- to 50-acre area within their home range).

There are observable effects, though. Bucks tend to move shorter distances from their bedding areas in daylight, confine themselves to smaller core areas, and do not venture far from bedding locations when hunting pressure is applied to an area. But they generally do not pack up shop and run cross-county to find a new home.

Human Urine Will Spook Deer

I myself believed this one until a few short years ago. I always either held my bladder or employed the help of a plastic bottle. Then, one day, a disbelieving friend told me I was out of my mind to believe urine spooks deer. He then proceeded to dare me to take a leak in an active deer scrape, put a camera over it, and watch what happens.

Well, being the fella I am, I couldn’t back down from a bona-fide dare. I took the challenge like a man and did it. And wouldn’t you know, buck activity (even among older age classes) actually increased within 24 hours (as compared to before the urination experiment). I’ll be danged.

Coyotes Don

Image 12 of 20

12 | Coyotes Don't Impact Deer Populations

Those who propagate that coyotes aren’t causing significant deer population declines either haven’t looked at the research or are willfully ignorant. We’re currently in a war with coyotes. People don’t realize that we must appropriately and efficiently manage this species just like any other. And what we’re doing now isn’t working.

Studies on the Savannah River Site in South Carolina have shown that fawn recruitment rates (as high as 1.2 to 1.3 fawns per doe), have declined to around 0.2 to 0.3 fawns per doe. This change correlates almost perfectly with the increase of coyote populations. And of that number, 60 to 65 percent of that fawn mortality was caused by coyotes.

In other words, in parts of South Carolina (and many other states), it’s taking five adult does to keep one fawn alive to see its first fall. These numbers range from 0.2 to 0.6 for many states in the eastern half of the country. The only state left with a fawn recruitment rate higher than 1.0 is Kentucky. It's the worst in areas without an abundance of quality early successional habitat.

The October Lull Is Real

Image 13 of 20

13 | The October Lull Is Real

Study after study, even on pressured properties, has shown deer movement does not decrease during the month of October. Daytime and nighttime deer activity gradually increase from September to November.

The biggest reason hunters believe in the October lull is because deer transition from summer to fall ranges between mid-September and early October. Not only that but also they transition from summer food sources to fall food sources, too.

Another factor is pressure. Deer have reacted to hunting pressure by the time October rolls around. They don’t always go nocturnal. They move to nearby areas — it can be a few hundred yards or a mile down the road — where less hunting pressure is present.

Deer are going through a lot of changes at this time and most hunters don’t change their stand locations to follow these changes. They keep hunting in locations they were seeing deer before and ignore where deer have moved to. Hunters must constantly adapt.

Culling for Antler Quality Is Effective

Image 14 of 20

14 | Culling for Antler Quality Is Effective

The vast majority of antler deformities are injury-related, not genetic. Injuries to the pedicle and velvet antlers during the growing phase and bodily injuries (these show up the following and subsequent years) will often result in deformities in the antler. Killing a deer with such a deformity does nothing to improve overall antler production in the herd.

Another reason “occasional culling” is ineffective is because both the buck and doe contribute to the genetic makeup of a buck’s antlers. Therefore, it is virtually impossible to influence antler production in wild whitetails by culling “inferior” bucks.

Lastly, recent studies show that many bucks (on average) may only sire one to three fawns in a year. Other bucks do well to sire that many fawns in a lifetime. So taking out that one deer — if it has genetically-undesirable antlers — will have very little effect on the overall gene pool. Other studies produced results that showed no change between two adjacent farms where one operated under a “cull” policy and the other didn’t.

Culling is not an effective method of increasing overall antler production. The two factors that real-life hunters can influence are age and nutrition. Let deer get older. Give them more nutrients necessary for good health. See bigger bucks.

15 | Deer Can't See in Color

The tall tale that deer can’t see color is yet another myth. They don't see in black and white per the popular myth. Deer see dichromatically. In other words, deer are red and green color blind. That said, they can see the color blue 20 times better than we can. Ultimately, deer see in blues and yellows. So I’d advise against wearing your blue jeans to the stand anymore.

This is also the reason that deer see best at dawn and dusk. During these times, it's a very bluish-grey hue outside. Deer benefit from that. And that’s one of several reasons why deer move most during those two times of the day.

Spread Trumps Mass When Scoring Deer

16 | Spread Trumps Mass When Scoring Deer

Boone & Crockett has measured a lot of deer throughout the years. Quite a few bucks have been entered into their books. It’s safe to say they have the scoring thing pretty well figured out.

And that’s why it's crazy when people say spread is more important to scoring than mass. That’s incorrect. You get way more inches out of a rack with heavy mass than a 30-inch inside spread and 25-inch main beams. It’s just the way it is.

New (and old) studies alike show deer move just fine when the wind is whippin’. To stay at home just because it’s windy is a cop-out. It’s an excuse. Because deer activity does not drop off significantly when the winds come. If that was the case, no one would ever kill a deer in the wind-swept Midwest.

20 | Wounded Deer Always Run Downhill

This is potentially my favorite myth on this list. It's the old saying that all wounded deer run downhill and toward water. While it might be true that deer sometimes do this, to say that it’s full-proof is doing hunters an injustice.

I can think of countless deer that I’ve killed and those of other’s that I’ve helped track that didn’t go downhill or toward water. In fact, the Kentucky buck I killed last year started out going downhill, only to turn and climb a steep incline, and falling dead at the top of it in a clearing. Mortally wounded deer don’t always run downhill.
