How Weather Conditions Affect Hunting

By GrowingDeer,

It’s warmer than normal across most of the whitetails’ range. Warm weather during January is usually associated with swirling winds. Looking at the weather forecast below, the wind direction will go around the compass during the next day or so at my place. That makes hunting conditions tough.

However, that’s not the only ramification of warmer than normal temperatures this time of year to a deer hunter and manager. At this point in the season deer have a full fur coat. It was created to retain heat during extremely cold conditions for the area where those deer live (this is one reason deer shouldn’t be transported to new areas with different climatic conditions as they may not be adapted to thrive in the different conditions).

I don’t feel like moving much when I’m hot. Likewise, deer tend to limit their activity until the coolest times of the day when it’s hot relative to the normal conditions (60 in January when deer have a great fur coat probably makes them feel much hotter than when it’s 90 in July when they have a very thin summer coat). The coolest temperatures usually occur during nighttime. Hot temperatures during the late season encourage nocturnal activity. These factors make hunting deer very difficult during the late season when the temperatures are much warmer than normal for that time of year.

However, there are other considerations about warmer than normal temperatures during the winter. Deer ingest more food when they are colder – at least to a certain point. An exception is that if the temperatures get significantly colder than normal, deer tend to remain in cover and limit their activity.

Deer will produce larger antlers the following year if they consume more quality food (within limits) during the winter. It seems that warmer than normal temperatures probably result in deer consuming less food, and therefore potentially smaller antlers the following year.

I enjoyed walking to my stand yesterday without carrying bulky clothing. I never felt a chill the entire evening. Although I was comfortable, I would have gladly traded my comfort for colder temperatures and seeing deer during that hunt, and the hope of the local herd producing larger antlers and healthier fawns during 2012.

Slightly colder than normal temperatures during the late season probably result in better hunting, and healthier deer the following year. How are the weather conditions where you are hunting?

Bucks Shedding Antlers Early

By GrowingDeer,

Adam called me two days ago with a bitter sweet message. He had found a shed from Giant 8. It was bitter because I had used some Reconyx cameras to understand Giant 8’s post late season feeding pattern. I had a Muddy hung, and felt I could tag him when the temperatures dropped and he needed to feed more during the daylight to gain calories to maintain his body weight. That plan is now canceled.

The sweet part is that his shed was found in one of two food plots that I had determined where Giant 8 was feeding. My scouting was spot-on! In addition, I’d rather the shed be found and confirmed it was a clean shed (no sign of injury, brain abscess, etc.) than he simply disappear.

I host an annual shed hunt during March. Even though March is relatively late for many shed hunters, we always jump a buck or two that still has antlers. However, I have multiple images of bucks that have shed early this year. In addition, folks from throughout the whitetail’s range have commented on my Facebook page about bucks shedding early in their neighborhood.

I expected bucks to shed earlier than normal this year – but not this early. Bucks will shed early when they are stressed. It was the fourth driest summer on record where I live. In addition to the lack of moisture, several months were recorded as the hottest or some of the hottest on record. Those hot and dry conditions caused a huge amount of stress to Eagle Seed beans planted in my plots. I was shocked they grew as well as they did – my other crops perished.

To a deer manager, forage plants are simply nutrient transfer agents. They simply transfer nutrients from the soil and air to the consumer (deer). No matter how many nutrients are available, plants can’t transfer nutrients without water. Soil moisture was so limited this year that the plants simply couldn’t transfer many nutrients. The heat directly and indirectly caused a huge amount of stress to bucks in my area this year.

I was shocked that the antler production was as good as it was during 2011. This was confirmed by comparing some sheds we found last year to some mature bucks that were harvested here this year (most notably Giant 10). I was pleasantly surprised that they actually produced larger antlers than during the previous year when the growing conditions were much better! This is a great testimony of the relationship between age and antler development. If you wish to harvest bucks with larger antlers, allow the bucks where you hunt to mature and provide the best nutrition you can afford. Food plots are relatively easy to produce and can definitely yield great results in allowing bucks to be healthier (larger antlers) and easier to hunt.

However, a buck’s antler growth potential (genetic potential) can only be expressed if the buck is allowed to live until it reaches older age classes AND has access to quality nutrition year round. It seems my buck hunting may be over soon even though the legal season where I live extends to January 15th. I learned some very valuable lessons about managing for and hunting mature bucks during the drought of 2011. I’ll be a better manager during 2012. I will continue sharing what I learned in this blog and each week in the video episodes of http://www.GrowingDeer.tv. Thank you for being part of the http://www.GrowingDeer.tv team and for sharing what you’ve learned and observed with us. May you be blessed with a great 2012.

Predators and Prey

By GrowingDeer,

I posted an image on Facebook of Matt, my intern, with a bobcat he’d trapped this week. I was surprised that image resulted in name calling and arguing among readers of that page. Folks were either thrilled with the removal of a predator or offended that someone would trap a predator.

Bobcat trapped off of Missouri deer hunting land.

Bobcat that was trapped to help balance predator & prey species.

I trap and call predators for many reasons. I enjoy the challenge of matching skills with a predator. My family and I really like the pelts and we enjoy giving them as gifts. Just as importantly, I wish to attempt to balance the predator/prey relationship on my land so there are plenty of prey (turkey and venison)  for my family, our guests, and for the remaining predators to eat.

When I was a younger boy (I’m 50 now), raccoon hides sold for $40+ in my neighborhood and gas was $0.70 per gallon. Now raccoons bring less than $10 in the same area and gas is $3.00 per gallon. We all know the price of fuel, steel, etc., has increased dramatically. There is very little incentive for trappers, except for the love of the work, to remove predators. Predator species have few predators in most areas.

“Balance” is a tough objective to achieve in most aspects of wildlife management. This is because the habitat and populations are always changing. It is a fantasy that wildlife populations or habitat will remain balanced without man’s intervention. Allowing either predator or prey species to build up too high always results in bad results. This has been documented time and time again in species like deer, rabbits, wolves, etc.

However, given that the habitat resources are becoming more and more limited, big swings in population levels don’t recover as easily. I don’t wish for predators – bobcats, opossomus, fox, raccoons, coyotes –  to remove most of the prey species -turkey poults, and whitetail fawns – at my farm. I want there to be enough turkey and whitetails  for me and the predators. There aren’t many predators of bobcats and coyotes where I live. There certainly aren’t many trappers in my neighborhood. So my efforts to trap some predators will certainly not hurt the coyote or bobcat population in the county.

We tend to actively manage the game species, but have shifted to a protection mindset for predators in some states. On my property, I will work to maintain a reasonable balance between predators and prey. The balance to me means there are plenty of prey (turkey and venison) for my family and the predators to eat. Having just enough prey for only the predators to eat and me shifting to playing ping pong is not an option. I’m going to work to provide good quality habitat which benefits both the predators and prey species, and trap and call to make sure the predators have a predator. Are you managing all the species on your property, or just the prey?

Hunting Timber versus Row Crops

By GrowingDeer,

I’m returning from hunting in Kentucky as I write this. I hunted a friend’s property that is primarily timbered. Timbered means that much of the sun’s light doesn’t reach the ground during the growing season as it’s captured by the trees’ canopy. The lack of sun reaching the dirt means food production for deer (and many other forms of wildlife) is limited.

http://gomuddy.com/shopping/Departments/STANDS.aspx

Several deer in field at a row crop farm.

Limited food means limited numbers of deer compared to habitat types like row crops (corn and soybeans) or the prairie. In these areas most of the sun’s light (energy) reaches the dirt or at least the crop’s canopy which is within a deer’s reach most of the year. More food, more deer. I like hunting where there are more deer (I call that a target rich environment!).

Another advantage of hunting in row crop or prairie areas is visibility. Less than 20 miles from where I was hunting on the timbered property, I toured a corn and soybean (row crop) farm. It was a well managed farm with excellent crop production and cover strips for wildlife and erosion control. It was a great example of farming for profit while managing a percentage of the land primarily for wildlife (farming and wildlife can co-exist while profits are maintained). I counted more than 300 deer during a brief tour!

The weather, date, etc., was the same as while I was hunting on the timbered property. With three of us hunting, we saw fewer than 20 deer from the stand during three days of hunting.

I felt very confident I could have grabbed my bow and Muddy stand and harvested a good buck within a day or two at the grain production farm. It was very obvious where the deer were bedding and feeding, and where they were traveling from one to the other.

Many other folks have made this same observation. This is why hunters migrate annually to the row crop areas of the Midwest to hunt and most hunting shows are filmed there. It’s simply easier to pattern deer in areas where most of the land base is open and visible. In addition the cultivated crops are outstanding food for deer and allow them to express most of their genetic potential.

That’s not to say that hunting in the timber isn’t fun. My place is mostly timbered and I enjoy hunting there. However, I usually spend several months  trying to pattern and harvest a buck. I can usually accomplish the same goal in much less time when hunting areas where row crops are the dominate habitat type.

I enjoy hunting anywhere – but know my chances for success are better where there’s lots of sunlight reaching the dirt!

Hunt Mature Bucks with a Predictable Pattern

By GrowingDeer,

The second chase phase (the period of the rut after the lock down phase) is on or winding down in most parts of the whitetails’ range (excluding parts of Alabama, Florida, south Texas, etc.). This means a small percentage of adult does haven’t bred yet, and most of the yearling female fawns haven’t bred yet.

Bucks will be moving more searching for receptive does and for quality food resources. Likewise, does will begin moving a bit more as the intensity of the rut decreases as both does and bucks are seeking sources of quality food.

The quantity and number of locations with quality food is decreasing with the winter temperatures, unless supplemental feed is used on the property you hunt. Therefore identifying the preferred feeding location for deer is becoming easier. That’s great news for hunters!

However, it doesn’t mean hunting is becoming easier. Hunting season has been in effect throughout most of the whitetails’ range for several months. Mature deer are very conditioned to avoiding hunters at this stage of the season. Therefore, identifying the preferred food source is only part of challenge.

Chasing deer that are experienced at avoiding hunters is no easy task. The leaves are mostly off hardwood trees so stands that offered great cover a month ago now leave the hunter wide open.

Good camo, especially on the face and hands (the parts of a hunter that move the most when they are in a stand) is a must. Remember that deer see movement much better than they see cover.

Deer may be conditioned to avoid some fields during daylight due to the amount of hunting in that location already during the season. If that’s the case, select a stand location between the bedding area and the field. Better yet, if practical avoid hunting some plots until the late season. Let deer become conditioned to feeding in an area without being disturbed by hunters. Those are dream locations during the late season. I often use an electric fence to protect small plots until the late season. These plots would have been totally consumed if not protected by the fence.

Finally, with the colder the temperatures, the more deer need to feed to maintain their body temperature. Colder temperatures usually result in deer feeding during daylight hours. Mature bucks will be feeding in the plots that haven’t had much hunting pressure and I plan on being there. The late season usually offers some of the most predictable deer activity throughout the entire season.

I ordered some heated insoles for my boots today. I’m hoping for some very cold days during the late hunting season. It’s worth getting a little cold to hunt mature bucks that have a predictable movement pattern to specific location.

Hunting The Second Chase Phase of the Rut

By GrowingDeer,

Last week I wrote about the lockdown phase of the rut. That phase of the rut can be some tough hunting as mature bucks don’t travel much except when finished tending one doe and seeking another receptive doe. Does tend to remain receptive (in heat) for approximately 24-36 hours.

However, during the next few days whitetails throughout most of their range will enter the second chase phase of the 2011 rut. This occurs when most of the does have been bred and bucks are seeking a receptive doe after a few weeks of finding such a doe almost daily. A huge factor in the length of the lockdown phase at any location is the adult sex ratio.

If the adult sex ratio favors does, then bucks don’t have to search as much or compete for receptive does. Some does won’t be bred during their first receptive cycle and will become receptive again in approximately 28 days. Often the phases of the rut in these herds are not well defined.

If the adult sex ratio favors bucks (can be accomplished in herds where more does are harvested than mature bucks), then the lockdown phase usually only lasts about two weeks and there is intense competition for the receptive does. The second chase phase in such herds can be almost as good as the pre breeding chase phase.

There are two factors that dampen the second chase phase. The first is some of the bucks have been killed by hunters, predators, suffered injuries from fighting, etc. There are simply less bucks to harvest during the second chase phase compared to the first.

The other factor is that bucks have now been pressured for several weeks. They are proven skilled at avoiding hunters if they are alive during the second chase phase. These bucks are not easy to pattern or kill.

However, there are some advantages to hunting the second chase phase. There is usually less food available during the second chase phase. Hence, identifying the food source is easier than during the early fall. Likewise the days are usually colder and deer need more calories. Therefore, they will spend more time feeding each day. This is when quality late winter season food plots can be great stand locations!

I’ll be using my Reconyx trail cameras to see which bucks on my hit list are still alive, and which food plots the does are using. Then, I’ll hunt the travel corridors or the actual plots that deer are feeding in frequently in an effort to tag another mature buck this year.

My strategy for the chase phase led to the harvest of Clean 12. I look forward to seeing if this strategy leads to the harvest of another mature buck.

Lockdown Rut Phase

By GrowingDeer,

I grew up hearing and thinking the rut was the best time to hunt big bucks! Like most subjects, the more you learn, the more you use the terms “however,” “but,” and “if.” As I learned more about hunting and deer biology, the term “rut” got replaced with “pre-rut,” “the chase phase,” “lockdown,” and “post rut.” As I began understanding the facts and theories about these phases of the rut, I learned just how much site specific deer management impacts the behavior of local deer herds.

Big, mature buck chases a doe during chase phase of the rut.

I live and do most of my hunting in southwestern Missouri. In fact, I hunt primarily in Stone and Taney counties of Missouri. No matter where you hunt, herds with a higher number of mature bucks in combination with a balanced adult sex ratio usually provide better deer hunting. Bucks in these herds tend to respond to rattling, grunt calls, decoys, etc., better. There seems to be more activity during daylight hours (given the same weather conditions).

The best hunting is where a balanced adult sex ratio and older age structure exists among bucks  for a large geographical area. The larger the area the better! However, the quality of hunting (as far as interacting with deer expressing all phases of the rut ) can be improved. Even on  smaller acreages where deer ranges tend to overlap the property lines on neighbors that still practice “if it’s got horns, shoot it.”

In that scenario, the best hunting is usually during the later stages of the pre-rut or the chase phase of the rut. This is when bucks are searching for does, but the does are not receptive yet. Therefore, the bucks tend to be on their feet more hours throughout the day.

When a majority of the does are receptive, many of the bucks (young and old) will be paired up with a receptive doe for 24-36 hours. Often times a dominate buck will stay within 10 yards of a doe while subordinate bucks stay in the area trying to sneak in for a date. Does rarely move much in this situation, so the bucks don’t cover much ground either. When the peak of breeding is occurring, hunters are less likely to see deer.

I’ve heard from several of my hunting buddies from South Carolina to Kansas during the past few days and none of them are reporting seeing many deer. It appears many deer herds are currently in the lockdown phase of the rut.

I’ll keep hunting, but I’m looking forward to the post rut when once again just a few does are receptive and mature bucks are cruising trying to find a date and feeding. There’s another peak of mature buck activity coming and I’m eagerly waiting. I’ll share with you what I know from a hunter’s and scientist’s point of view next week.

The Chase Phase of the Rut

By GrowingDeer,

Mature bucks are beginning to chase does throughout much of the whitetail’s range. It’s a time of year that literally millions of deer hunters schedule their vacation and with good reason.

If you hunt close to home, you can pick days to hunt when a weather front is passing, or you’ve found a limited resource such as a pond during drought that deer are actively using. However, if you are traveling to hunt then the chase phase allows you to plan a year in advance and puts the odds in your favor that mature bucks will be active during daylight hours. During the chase phase of the rut mature bucks tend to be active during the daytime even if the hunting pressure or air temperatures are a bit higher than normal.

The October Lull phase of deer activity just passed. This is when deer, especially mature bucks, have grown their winter coat and food is usually plentiful. Deer don’t have to travel far to find food, and they aren’t burning many calories to stay warm or chase does. Mature bucks simply don’t have many reasons to move during daylight in mid-October in most regions.

However, with each passing day now more and more does will become receptive. Bucks will be moving in search of the few does that are receptive. For the next several days, more and more does will become receptive until the peak of breeding activity. During the peak of breeding activity, most mature bucks will stay with a receptive doe for about 24 hours. This is called the Lock Down phase of the rut. During this time, mature bucks typically only move when they are finished tending one receptive doe and are seeking another.

The woods can seem almost void of deer during the Lock Down phase. This is because it’s not only the mature bucks that tend does. In fact, multiple research projects have now shown that mature bucks only breed slightly more does annually than immature bucks. Not many deer will be moving when most of the does are receptive and most of the bucks can have a date.

In addition, the duration and intensity of each phase of the rut varies location by location based on the herd’s adult sex ratio and health. Herds with a balanced (or skewed toward bucks) adult sex ratio seem to have the most intensive rutting behavior. There’s much more to the science than what I’ve shared here.

So, if you enjoy hunting the chase phase of the rut, get out the door! It’s time to go hunting! If you choose to plan ahead for your hunting vacation next year, the first and second week of November is usually a good option for hunting mature bucks in most areas of the whitetail’s range. There are other times of the year that can be very productive, but they are very weather dependent. The local weather can’t be predicted accurately enough to plan vacation time months ahead. However, weather isn’t as big of a factor during the chase phase of the rut, so it’s the safest bet for scheduling hunts that require packing a suitcase!
