Beware the “Rules” of Deer Behavior
By Dave Hurteau
I’m sure you’ve read many times, as I have, that “whitetail bucks bed with the wind at their backs and a good view out front.” That sounds pretty darn good. This way they can detect danger from front and back. It makes so much sense, in fact, that it’s almost a little annoying that so many deer don’t bother to follow along.
By the same token, I recently read that bucks bed on slopes and below the points of ridges because falling thermals warn them of danger from behind while their eyes, scanning downhill, catch danger out front. That sounds darn good, too—unless you’re a person who actually hunts in hilly terrain, in which case you know that thermals don’t really start falling until pretty darn late in the day, often right before sunset. And so all those bucks bedded on slopes and below points, the poor dim-witted creatures, actually don’t have the wind at their backs, like they’re supposed to, for most of the day.
The other day Bestul reminded me of this one: “Savvy bucks always walk with the wind in their face.” This means that all the bucks you’ve seen—and some you’ve shot—walking with the wind behind them or to one side may have been big, mature deer—just don’t get to thinking they were savvy.
I do sympathize with outdoor writers, being one. As the average reader’s (not you) attention span shrivels and dies, it’s always, “Whitetail deer behavior in 300 words or less.” I’m just saying, in case you haven't noticed, that the rules we make up for whitetails—well the deer aren’t always listening.

You hit the nail right on the head. The only predictible whitetail behavior is unpredictability.
Deer are very predictable. It is easy to predict they will make you look like a fool.
After fifty plus years of hunting deer, about the only thing I can state with certainty is that" If buck's only mated at night, there wouldn't be many shot".
Biologists have stated that it is wrong to feed deer hay and grain during the hard winter months because they are in browsing mode and that they do not have the correct bacteria in their digestive tracts to digest the grain and hay. Apparently, deer can starve with full stomachs of hay.
However, during mid winter thaws hereabouts, I constantly observe deer foraging in meadows for hay and waste corn. Any thoughts on this?
Douglas, Very interesting comment. Have never heard of this theory. I always thought browsing was an instinct to stay one step ahead of the predators. This is why you do not see deer parked all day on a corn pile. Instinct tells them to keep moving before they can be easily stalked.
The digestive system of a deer is far beyond my knowledge of deer but I do know they can be patterned based upon the food source available for the time of year. I know of a leafy green vine which grows in the fields which deer crave when most green browse has turned brown. I wonder if the change in diet affect the digestive system.
Bioguy has been busy darting deer. I hope he takes a moment to chime in on this.
buckhunter,
There is a recent article online you might want to check out titled "Unintended consequences of deer feeding" by Paula Piatt in the NY Outdoor News.

The only absolute rule of deer hunting is that there are no absolutes. Every year I hear a new one. From “deer will never eat apples until after the first frost” to “deer will never move with the wind at their backs.” One trick about hilly terrain is that the deer are limited to where they can go based simply upon physical obstructions. If moving upwind means the deer has to ascend a 90 degree cliff face, they might just break the rules a little bit.
Douglas - Though I have a pretty good background with deer, an article by Dr. David Hewitt, a deer nutrition expert, may shed some light on your question.

Basically, what it boils down to is deer need a wide variety of foods available to them throughout the year to remain in top-notch health. If corn or hay is the only thing deer have to eat, that's generally a bad scenario.
As for seeing deer in fields during thaws, once the snow comes off the fields, a whole buffet of foods are available...mostly in the form of young forbs which are full of protein. Deer need protein to build their bodies up after several weeks of feeding on low nutrition browse and combating the full brunt of whatever nature could throw at them. Think of it like this...a freshly thawed field is the equivalent of a gourmet buffet laid out in front of you after several week of eating nothing but cardboard.
In response to the article...you can make generalizations about deer behavior to a certain extent, but each individual is different, and they don't all follow the "rules." When the rut hits...take whatever "rules" you have heard and throw them out the window!
That said, mapping is a fantastic way to learn deer behavior, and today's technology makes it easy for the deer hunter to record observations and create maps. Personally, I like using Big Game Logic because its free and all of the tools I need for effective mapping are readily available and fairly easy to use. Prior to Big Game Logic, I used a combination of Google Earth and Mytopo.com. Whatever your preference, a great amount of deer behavior can be learned just by making maps.

Bioguy, Thanks for the information. It makes perfect sense. Deer behavior around my area has changed with the more open winters. They tend to stick around their summer range and not go to yard areas. Plus, there has been clearcut timbering on 20 - 30 acre woodlots that are regenerating and providing browse. Does letting round bale of grass hay "fall off the back of a wagon" where the deer can pick at during hard times cause more harm than good?
As far as I know, the “more harm than good” PSA campaigns deal more with people continually putting food out for the deer in their backyards throughout the winter. There would be two reasons for this concern. A) Providing a continual food source so close to dwellings engender further deer/human conflicts (car accidents, garden destruction and the like. B) A continual concentrated food source will unnaturally concentrate the deer herd. This could cause the deer to become dependent on humans for food, and if they would be deer feeders were to stop, it would mean the entire herd was cut off from its food source. The other issue with concentration is CWD. The causes for CWD are not fully understood, but it is believed that it is transmitted through deer urine that other deer pick up when feeding in an area where there are many other deer urinating. Putting out deer feed could engender this situation
I don’t know if any of this is actually true, but this is the sense I get from these campaigns. Bioguy would certainly know more about it than me. In any case, I doubt that the occasional hay bale or some loose forage in a farm field would have entirely the same effect. I suppose that it is possible though.
I have 1 hard rule:
No deer tracks, no deer. No buck rubs, no buck.
Smart bucks die of old age. Too smart and they get caught where they don't belong. big bucks don't get big following rules,they get big by staying unseen and doing the opposit of what they should by our rules.50 seasons account for many mistakes of being taught what to expect.The unexpected
I only have one rule when hunting the elusive whitetail - follow your instincts. We all been there, sitting in our spot, and a feeling hits us that this is just wrong. Personally I go with it, many times that feeling has hit me and I've moved spots just in the nick of time.
Dad was a fisherman and he used to say that big fish didn't get big by being stupid. That same logic plays well with deer. Especially here in Oklahoma where if it's got antlers, it's going to get hunted/shot at.
I like the rule about deer always walking with the wind in their face. I live in western Michigan where the prevailing wind is west-to-east. You wouldn't believe the number of deer herds that walk straight into Lake Michigan, never to be seen again until they resurface in Milwaukee:)
Dave, any good books on deer behavior? Always on the look out for new things to learn.
Until some genius comes up with a way to hook a bunch of electrodes to a mature buck's head and find what is rattleing around in there we will never why a deer does what a deer does.
