Once December rolls around, deer season is beginning to wrap up for most of the country. For those braving the winter conditions during late-season hunts, special preparation is required to ensure a successful outing. As weather conditions change, deer are forced to adapt to the harsh realities of winter. Behavioral adaptations, movement patterns and diets change significantly from fall into winter, and if a hunter wants to fill their tags, they must learn to adapt as well.
When temperatures begin to plummet, deer instinctively become less active to conserve energy, while also developing thicker coats and a thick layer of insulating body fat beneath their skin. It's almost as if a switch flipped in their brain, kicking them into survival mode. During harsh winters, deer will spend much of their time bedded down. Instead of roaming through the woods as they do in the fall, deer will begin to limit their movement to essential feeding and watering areas. Dense thickets and forests of evergreens are popular spots for deer to seek refuge against heavy winds and snowfall, rather than grazing in an open field. This reduction in activity makes their patterns more predictable, allowing hunters who have scouted in the preseason to position themselves in areas that offer the best chance of harvesting a deer.

With the deep snow further limiting the herd’s movement, hunters can set up in a prime spot where deer are known to bed down or browse. Deer activity can also be monitored by the tracks they leave behind in the snow, allowing you to see which direction they were heading and which areas see the most activity. While setting up shop in a deer blind or stand is the go-to, hunters shouldn’t be afraid to give still hunting a try. Nasty weather conditions will keep deer relatively sedentary. Still, if you're quiet enough and utilizing natural cover to the best of your abilities, you may be able to sneak up on them before they know you're there.
Preseason scouting efforts should include identifying feeding opportunities for when the eventual snow does fall. During the fall months, deer will feast heavily on nearby crops such as corn and soybeans, hard mast (acorns, hickory nuts, beech nuts), soft mast (apples, berries) and perhaps your favorite rose bush!

As these diet staples begin to die off, are harvested, or buried under layers of snow and ice, food sources become quite scarce in the late season. This forces whitetail to adjust their diets until warmer temperatures begin to thaw out their surroundings. During the winter months, their diet mainly consists of woody browse, including twigs, buds and leaves. Although not as nutrient-dense as what they consume during spring, summer and fall months, these sources of food provide just enough nutrition to help the deer make it through the winter while not completely burning off their stored body fat. Being able to confidently identify various plants and trees may seem like a daunting task, but being able to do so may lead you in the direction of hungry deer. You may find it beneficial to grab a book on native plants and trees in your area and use it to pinpoint potential feeding areas when the nastiest parts of winter take hold.
Snow gives deer hunters an advantage where deer are traveling back and forth between food sources and bedding areas.

Scouting before the season even begins will give you the best advantage, and trail cameras are an excellent tool for an inside peek at the action without disturbing the woods. Always keep an eye on the forecast, as drastic weather swings, such as immediately after a storm or during brief warm streaks, are prime times for deer movement. Positioning yourself near trails, funnels, or between a bedding area and a feeding area can yield excellent ambush opportunities. Take note of changes in feeding behavior.
While dawn and dusk still see plenty of activity, deer may be more active in the middle of the day to take advantage of warmer temperatures or to feed. Keep this in mind as you are tempted to head for the warmth of your truck or home between your morning and afternoon sits. Lastly, late-season pressure will inevitably make deer wary. During this time, use that knowledge to your advantage. Seek out areas that may be overlooked or somewhat difficult for other hunters to reach, as you will often find deer seeking to escape the pressure of being heavily hunted all season.

Perhaps one of the most important things to learn, often learned the hard way, is the importance of not going into the woods. With temperatures below freezing, it is only natural to want to bundle up with enough layers that you resemble Randy from “A Christmas Story”, yelling, "I can't put my arms down!” Sweat will rapidly cool your skin, and you will soon become unbearably chilly as you try not to shiver yourself out of your deer stand or blind. While not an end-all list by any means, the three items below are tried and true must-haves when the freeze sets in:
Base Layers: Look for moisture-wicking fabrics to prevent chill-inducing dampness. A snug yet comfortable fit is essential but shouldn’t restrict movement.
Insulated Coveralls: Their one-piece design provides full-body coverage, retaining warmth and blocking rain, snow and wind. Keep in mind that you may need to size up to allow for layering underneath.
Insulated Winter Boots: Prioritize warmth, waterproofing and traction. Check temperature ratings and choose quality insulation. Aggressive outsoles prevent slips. Pair with moisture-wicking socks to keep you warm and dry. Try boots on with your hunting socks, as bulkier socks may require you to size up.
One of the biggest keys to hunting deer in the late season is making sure you have the right gear to stay in the field as long as needed.

The list of essentials could go on and on, including battery-operated heated vests , hats, gloves, HotHands , and even Little Buddy Heaters for those hunting from a box blind. If you keep going back and forth on whether you need something, just bring it, especially if it's something that you can easily toss in or strap to your pack. It's better to have it and not need it than to call a hunt short because you left said item at home and are now shivering 20 feet up in a tree.
When it's all said and done, there's no denying that late-season whitetail hunting is not for the faint of heart. Yet, for those who embrace the challenge, this time of year can provide some of the most rewarding moments in the woods you’ll ever experience. By understanding how deer adapt to the harsh winter conditions, you can adjust accordingly and ensure your freezer is full season after season.
