Doe Harvest with Caution?

Not all that many years ago it was considered unsportsman-like to shoot a doe deer. Since then, however, wildlife biologists and hunters have realized that proper doe harvest is an important part of white-tailed deer management, although I suspect there is a small percentage of landowners that still do not allow doe to be harvested on their properties. After all, a landowner has the ability to be more conservative than the law and choose not to harvest antlerless deer, even if hunting regulations permit it.

But is a no doe harvest really justified? Maybe, but then maybe not—particarly if the only reason holding someone back is the “old school” philosophy of not shooting female deer. It is true that the shooting of does may not be justified in some areas. Not every deer whitetail population can sustain regular doe harvest. Some deer herds may allow periodic doe harvest, such as every other year or every third year, for example, while others need regular (annual) doe harvest to thrive. So why does the harvest of whitetail doe vary by area? Continue reading “Doe Harvest with Caution?”

Deer Hunting Improves as Rutting Activity Increases

The white-tailed deer gun opener was slow in Central and North Central Texas. The second weekend was not much better. However, cooler temperatures and good reports of rutting bucks moving throughout much of the state should make this coming weekend a great time to head out deer hunting! Although much of the state’s abundant acorn crop is now depleted, deer still have a choice between cool season forbs and lush winter food plots (where they exists). Areas that were barren during the summer are now a hodge-podge of high-protein forbs.

Except for the last couple of months, 2009 has been a tough year for most of Texas’ white-tailed deer population. The preceding winter, spring, and summer were dry. Very dry. Extremely dry. But all of that has changed. Deer that were in poor to fair body condition during the summer have gorged on fat-rich acorns are now looking to be in good shape. Although many ranches are reporting that deer body weights are lower this year compared to previous years, rainfall received during September and October have “saved” the year.

Deer Hunting gets better as the rut continues

Winter food plots, which are typically the most reliable plots, found themselves high and dry at this time last year. But not this fall. Anyone that stuck a seed in the ground is now the beneficiary of a lush food plot, regardless of what was planted. Recently, however, not all food plots were being hit hard. I suspect that many hunters that were reporting low food plot use by deer up until now should find that cooler temperatures will move more deer onto those plots, and earlier in the day.

More deer is a good thing, especially during the rut! I’ve received reports from throughout much of the state, except South Texas, of bucks following does for the past couple of weeks, but I’ve seen a marked increase in chasing activity over the past four to five days. Central Texas hunters heading to the field over the next week should expect to see good action. If you can find the does you will find the bucks, and deer should be hitting food sources well thanks to cool, brisk weather over much of the state.

As always, make sure to keep the deer population in check with available habitat. On average, the body condition of deer has increased greatly going into the fall thanks to a solid acorn crop and additional forage provided by much-needed precipitation. Antler quality has not improved; lower than average antler growth was a result of the tough winter, spring, and summer we experience through most of Texas. However, keeping proper deer numbers where you hunt is an important component of deer and habitat management.

Too many deer means less food per mouth, and if the rain turns off, next year could be particularly tough since we are still way behind on total rainfall. In short, don’t hesitate to harvest deer where needed. Get out and enjoy the cooler weather and put yourself in position to take advantage of increased white-tailed deer rutting activity. And remember, squeeze the trigger!

14 Point Franklin County Buck Saved

White-tailed bucks are an interesting lot. Individual bucks run together in bachelor herds during the summer, but become mortal enemies during the fall and winter. Most hunters realize the proper harvest of animals is essential for white-tailed deer population management, but we also hate to see deer die of natural causes, especially when self-inflicted. However, the life of a white-tailed buck can be tough.

In addition to surviving the seasonal stress periods of summer and winter, and sneaking by hunting season after hunting season, bucks also fight for dominance among themselves for the right to breed receptive does in the area. When big white-tailed bucks fight it is a sight to see. I have seen bucks spar for several minutes, although battles of several hours are well documented. I suspect that most encounters are intense, but short in duration (just seconds) with the stronger buck making his point rather quickly.

Two white-tailed bucks lock antlers in Franklin County, Texas

However, sometimes bucks will fight to the death. This happens when animals become gored by powerfully swinging points, when animals are pushed or knocked into natural obstructions, or when antlers lock and one or more bucks die from exhaustion and/or starvation. Such was the case last week when Texas Parks and Wildlife Department (TPWD) responded to a landowner’s call about two bucks locked together in Franklin County, Texas. TPWD does it’s best to manage the Lone Star State’s white-tailed deer population through surveys, hunting regulations, and law enforcement, but they also get hands-on with wildlife when the situation calls.

TPWD: “On October 20 Camp County Game Warden Heath Taylor received a call from a landowner in Franklin County about two bucks that he found on his property that had gotten their antlers locked together and were under a fence on opposite sides from each other. One buck was a 9-point that had already died but the other was a huge 14-point that was still alive but to the point of exhaustion. Warden Taylor notified Franklin County Game Warden Doyle Brown and both wardens met the landowner.

When they arrived, Warden Taylor and the landowner were able to pry the bucks apart and untangle the huge buck from the fence. After laying there for a couple of minutes, the big buck stood up and walked into the brush escaping what would have been certain death. Both the wardens and the landowner stated that it was one of the biggest bucks they had seen in this area.”

The Spread of CWD in White-tailed Deer

Serious diseases such as chronic wasting disease (CWD) can be detrimental to whitetail deer management programs with mortalities impacting local deer numbers as well as regional and potentially even statewide deer populations. State agencies around the country have been monitoring CWD in deer herds for many years now, and they know that it is caused by prions, but much about the spread of the disease was unknown until now. Researchers have discovered that deer asymptomatic for the fatal brain condition known as CWD excrete the infectious prions that cause the disease in their feces.

The finding suggests a reasonable explanation for transmission of the disease among white-tailed deer, mule deer, and possibly elk and moose in the environment. While the study reveals that prions are shed in feces of symptomatic deer as well, the discovery that the infected deer shed prions in their feces many months before they show clinical symptoms is the most unsettling. White-tailed deer, mule deer, elk and moose inadvertently consume feces and soil in the course of their daily browsing and grazing.

Chronic wasting disease (CWD) is spread through deer feces

The prion is an infectious form of the normal prion protein, which has been found in all mammals examined, including humans. The lethal, infectious form induces the normal protein to twist into a malconformation, initiating a disease process that ravages the brain. Prion diseases, seen in cervids, sheep, cows and humans, are also referred to as spongiform encephalopathies. In wid and captive deer, researchers now know that the inadvertant consumption of feces is how the disease is transferred from animal to animal. So what’s the next step?

With this information in hand, the researchers set out to determine whether the animals could develop chronic wasting disease through long-term consumption of contaminated feces. They did so by measuring the amount of prions contained in the feces of orally infected deer up until the time they became symptomatic and then calculated whether prolonged exposure to the concentrations of prions in these feces would be enough to cause the disease.

“Prion levels in feces samples of asymptomatic deer were very low compared to those in the brains of the same deer at the time of death,” says the lead author of the study, Erdem Tamguney, PhD, an assistant professor at the Institute for Neurodegenerative Diseases, based at UCSF. “However, the total number of prions excreted over time was sufficiently high enough to cause disease in other deer.”

The susceptibility of animals to infection, he says, may also be increased by the simultaneous ingestion of clay soil, which is thought to enhance the infectivity of prions, possibly by slowing their clearance from the gastrointestinal tract.

“Our findings suggest that prolonged fecal prion excretion by infected deer provides a plausible explanation for the high level of transmission of chronic wasting disease within deer herds, as well as prion transmission among deer and other cervid species. Our work may also explain transmission of scrapie prions among sheep and goats,” says senior author and Nobel laureate Stanley B. Prusiner, MD, UCSF professor of neurology and director of the UCSF Institute for Neurodegenerative Diseases.

The study did not examine whether CWD could be transmitted to humans via exposure to deer feces. To date, transgenic mouse studies have indicated that chronic wasting disease does not transmit to humans, but scientists remain open to the possibility that it could.

“We can only say that prions of chronic wasting disease have not transmitted to mice genetically engineered to carry the normal, healthy form of human prion protein in earlier studies,” says Prusiner. “That said, we do not know for sure that deer or elk prions cannot be transmitted to humans.”

Time to Rattle for Whitetail

Fall is here, food plots are in the ground and the deer hunting seasons are underway. Except for conducting a couple of controlled burns in the near future, the only thing left to do deer management wise for me is to harvest and record the deer we need (or would like) to remove. Though most deer hunters hunt whitetail by setting up over a food source, whether it be a feeder or a food plot, there are much more active ways to bag a buck.

When it comes to hunting there really are only two ways to go: Either you can go to the deer, or you can bring the deer to you.

Rattling for Whitetail Bucks

Rattling for Bucks

Though many hunters have read about rattling bucks in, or have at least seen it on TV, many have yet to give this method of hunting a serious shot. Or maybe you tried it once, but didn’t feel confident, it didn’t work so you packed it in. Ratting for bucks can work, especially if you incorporate the technique into your hunting on a regular basis.

I suspect many deer hunters have picked up a set of shed or cut-off antlers and have at attempted to rattle up a buck, but their lack of success caused them to quickly dismiss the effectiveness of antler rattling. Those antlers then went back to collecting dust at camp. So as effective as rattling can be for whitetail, most of time it will not work and you are not going to bring in a buck on a string. It does work, however, and when it’s hot, it’s hot!

Best Time to Rattle?

Rattling can work at any time during the hunting season, but it is typically most effective just prior to the rut, during the pre-rut. At this time, antler rattling can be an effective way to bring whitetail bucks right up into spitting distance. I’ve seen bucks come running out of the brush with as little as two seconds worth of antler rattling!

Of course many, many  times I’ve rattled antlers together only to attract the attention of  area squirrels, or even worse, nothing at all. During the pre-rut, bucks are busy establishing dominance for breeding purposes, setting up territories, and working off an excess in testosterone. It is also during this time in which they are most vulnerable to rattling, so this is the BEST time to rattle.

Rattling Antlers Attracts Attention

When it comes to rattling, let me tell you that you never really know what you are going to attract. I’ve had all sorts of deer respond to rattling. I can only guess they all want to run over and see who is fighting — and who will win? Some bucks want to participate, some are just curious. I’ve had does, spikes, middle-age bucks and mature bucks all come to a set of rattling antlers.

All age classes of bucks will respond to rattling more or less at the proportion in which they occur in the population. Younger bucks probably respond at a higher percentage overall and mature bucks probably a little less overall, but it’s not easy to measure since mature bucks are smarter. Older bucks often respond to the sound of rattling antlers by moving downwind of the action and then creeping in. Younger bucks do not always take such precaution, so there is a chance some of those more experienced bucks are detecting us before we detect them.

If a good percentage of the local buck herd is made up of young bucks, then that is probably what you will bring in. If, on the other hand, there are a good number of older bucks in the area, then you have just as a good of a chance of bringing them to you as younger-aged bucks. In fact, you probably have a much better chance of bringing them to you rather than simply sitting and waiting to see them — because they may have stayed “brushed up.”

A whitetail buck responds to rattling

Rattling, Battling Bucks

A friend of mine spotted a huge whitetail buck last year on public land right as the season started. The buck showed up on a couple of his game camera photos before season, but he got a glimpse of the buck the second day of archery season as the animal walked by at 200 yards. At that point, he then made it his personal mission to hunt that deer for the remainder of the season, even if it meant he ended the year with no buck at all.

To make a long story short, he hunted long and hard with no success, but one cold morning a few weeks later he decided he needed to be more aggressive. He had decided that if he didn’t change then his success rate was not going to change. The best trick in his book: try to get near the buck’s core area and rattle him up for a battle.

The right day came: Temperature perfect, wind great and he was able to rattle that buck to within 25 yards and made a perfect double-lung shot. He said after his first rattling sequence he could see the buck, which scored over 170 Boone and Crockett inches, running at him from over 400 yards! Sometimes it helps to bring them to you.

So rattling can work, but don’t expect it to work every time.
