White-tailed Deer in September

When it comes to deer hunting you just have to love late September in Texas. It is at this time of year that hard-antlered bucks show hunters really what they have to offer, and hunters search the woods for sign left by these pre-rut bucks. As testosterone levels rise, bucks remove the velvet that covered their growing antlers for the past 6 months. The act of a buck rubbing his antlers against a trees not only removes the dead, rotting velvet, but also helps strengthen the deer’s neck, shoulders and body as he prepares to do battle with his summertime friends.

September is rarely a time for hunting deer in Texas, except during those years when the Saturday closest to October 1st happens to be in September. No, most of all this month signals that deer hunters had better get their acts together. It’s time for placing out those last minute stands and deer feeders. It’s time for talking about deer, buying seed, and planting winter food plots. It is during this time of year that the eager hunter anticipates each trip to the game camera, never knowing what he or she may have captured.

Hunting the Rut - Look for Bucks Chasing Does

Most landowners participating in Texas’ Managed Lands Deer Permit deer management program have already wrapped up their deer surveys for the year, have received their harvest recommendations, and are ready to start working on achieving their harvest goals. It Texas, so it seems, a deer managers work is never done.

The recent cool front that pushed through most of the state this past week has really got the deer acting a bit frisky. No, I’m not eluding that the rut is on, at least not in most parts of the state. But believe it or not, research has found that many deer do rut during the month of September. In some instances, fawns are even conceived during late August! This is not the norm for the bulk of the state, but for deer living in the Gulf Prairies and Marshes this is not uncommon. Data from Texas Parks and Wildlife Department found that the peak breeding date for white-tailed deer in the northern portion of the coastal prairies was… September 30.

But just as some does breed early, some deer will breed late. This can cause confusion among hunters because one hunter will proclaim the rut is over in an area while another argues just the opposite. It’s the ole early rut versus the late rut argument. The truth is that deer will be bred throughout the fall and winter. Most of the older does will come into estrus earlier with the younger does following. Fawns born this year can also be bred by bucks in late winter, such as during January and February.

This weekend I plan on heading out to do some bowhunting in Colorado County. From past experience, I fully expect to see some bucks chasing, but I’ve been wrong before. I guess that’s why deer hunting and deer management are two different things. It’s easier to manage a population of deer than it is to hunt a specific deer. But I enjoy the challenge and hope to learn a little more each time I walk into the woods.

  1. I guess the term late rut is often used in relation to breeding in younger deer, since it was said that older does breeding earlier. I know there is some debate on the fact that older does are more likely to have twins. Do we see that older does have a greater chance of having twins? In the past spotlight surveys on my property I am unable to identify this correlation. Is there any data that might support this theory?

    If so, should some of us take this into consideration when selecting our deer to harvest?

  2. In answer to the question Travis posed, older DOES tend to have twins. The younger DOES age 1 yrs or so can have twins, but it is seldom seen. Your mature DOES are more likely to have twins than singles, but only IF they are getting adequate nutrition DURING and AFTER fawn gestation. Most older does will have twin fawns, but understand that even with great nutrition predators will get some too.

  3. Do we see the “rut” being affected by the amount of nutrition?
    Thought: The spring rains came and went… We have seen better fawn survival rates and better conditioned deer early in the season. Does this affect the cycling of the deer? In theory, it should.

  4. Yes, the rut can be affected by deer health, which is a function of nutrition. Deer in way better-than-normal body condition tend to breed earlier in the breeding season, while deer in poor condition respond later.
