I have spent a lot of time in the woods, just wandering around and watching how animals interact.  I have always been a firm believer in learning by observation.

You can read lots and lots of books, magazine articles and watch tv shows but sometimes you need to take that info into the field and watch the words come alive to truly understand the content.

When hunting whitetail, hunters in general tend to spend a lot of time focused on scrapes and rubs. 

Hoping that if they post up over a good scrape that monster buck will magically appear to "freshen" it up at some point in the day.

Honestly, I don't really pay that much attention to the scrapes and rubs unless I've patterned a buck and I personally see that he goes to XYZ scrape every morning.

But with that being said, scrape hunting can be very effective if done right.

 

Before I realized that I had much more luck focusing on food and cover sources, I too would scout and find a big rub and sit over it for 3 days and then curse in 7 different languages when that buck would refuse to materialize.

What I didn't realize was there are a few different kinds of rubs, deer will rub against trees to remove the velvet from their antlers, they will actually fight with bushes to strengthen themselves, and I firmly believe that sometimes, smart mature bucks will leave rubs at eye level to advertise to does that he's there. Sorta like grafitti "Big Buck In Da House"...

But taking that in to account, even a fresh rub may be just a deer trying to get the velvet off or as he passes he just doesn't like something about that tree and takes a few whacks at it!

Scrapes are a bit of a different story, I have read reports that northern deer do not make as many scrapes as southern deer due to the lack of breeding pressure.

I'm not a scientist or a deer biologist, who has studies all over the country, but the Wisconsin doe to buck ratio is 2:1 and we have more than 700,000 whitetail deer currently.  Take the bucks too young to breed, or the younger ones who aren't strong enough to fight off a bigger buck out of the equation and the mature breeding bucks stand a greater chance of attracting does in heat.  Hence many zones in Wisconsin being earn a buck where you had to harvest a doe before a buck to control the population.

 

Like us, deer tend to follow the path of least resistance when walking.  A game trail that is easy to walk is obviously going to be the most beneficial for the buck to make his scrape along.  If he's walking along that path, chances are other deer will too.

I'm sure there is some sort of genetic instinct that lets them know if you make a scrape in thick brush where it's hard to get in, chances are...no one will know its there.

 

In my opinion, there are actually two essential parts to a scrape.  The scrape on the ground; and the tree branch hanging above it.  A scrape is made (usually) after a deer has gently chewed on an overhanging branch.  There are chemicals secreted by their salivary glands, their own personal scent if you will, that are left on those branches.

I liken it to the way my cat will occasionally rub the corners of her mouth on furniture, toys and even me.  She's marking those items as "hers".  The scent that's secreted from her saliva would be detectable if another cat were to come into "her" house.  She's letting everything and everyone know she's marked and taken ownership of this item and she is in residence.

That is exactly what a mature buck does when he's chewing or even licking those branches.  He's leaving his scent behind for both does and other interloping bucks to know he is in residence.

 

Past experience has told me that many hunters don't even take the really high branches into account.  But think about it, haven't you ever seen a buck stand on his hind legs?  He's a pretty tall dude when he wants to be.

 

So a buck will lightly chew all over a branch, covering it with saliva, and if the branch is low enough he may even rub his forehead on it as well, deer have all sorts of scent glands and they are adept at making use of them!

 

The scrape itself is usually located directly beneath the overhanging branches.  I personally think the main object of a scrape is to get rid of any debris whose scent might compete with his.  Dead leaves, sticks, pinecones etc, all have odors to them so, let's start with fresh basic soil.

The deer will then rub his back legs together, stand in the scrape and literally urinate on his back legs.  The scent front the glands on his back leg mix with the urine to create a secondary distinct scent that simply says "ME".

(Have you ever seen a buck do this?  It's the weirdest thing I've ever seen!  It simply amazes me the lengths a buck will go through to mark his territory and attract a doe!)

 

Scrapes can be extremely useful in patterning a buck.  If you pay attention to which way he was scraping you'll be able to tell which way he was going.  If the dirt he kicked up is west of the scrape chances are he was heading east when he stopped to kick up some dirt.  You can also watch for does that may urinate in the same scrape.  They too are letting any bucks know that she's "in residence" and more than willing to do some entertaining.

 

*This brings up a side note regarding any kind of lure in a bottle you may purchase.  Neither buck nor doe will urinate on a scrape to completely empty their bladder.  They urinate just enough to leave their scent and let the other know they are there.  So using the lure scents sparingly is not only cost effective but it's also more realistic.

 

The reason I rarely hunt scrapes now is because I believe most mature bucks become somewhat nocturnal in the fall, and especially during the rut.  Or maybe not quite nocturnal just 2nd shifters.

So if you're sitting on a scrape day in and day out, you can see that it's being refreshed every day but you never see the deer?  It's probably because he's checking that scrape after hunting hours have ended.  During the rut, the deer's natural territory expands by several miles.  He might not even have enough time in the day to get back to that particular scrape before you leave anyway!

 

All in all, rubs and scrapes can be a very useful tool to some hunters and may be a waste of time to others.

 

So here are a few questions to all you BowCasters out there:

#1.  Do you hunt over scrapes?

#2.  How successfully have you been?

#3.  What tips would you share with me if I told you "I'd like to hunt over a scrape but I've just never had any luck"?

Deciphering the pattern.
written by Toasteo, June 26, 2009
Great topic. Whitetail deer are one of the most common animals in North America but we're still trying to find answers to basic questions. I like your observations on scrapes and rubs. I agree with everything you said. I think one of the most useful tools we have today as hunters is scouting cameras. A scouting camera can help you to determine if a scrape or rub is active or if it is just a random tree thrashing. Something I started doing last year that has really opened my eyes to patterning deer is to keep a daily weather journal and use it in conjunction with your scouting camera. It's super easy. I just print off the hour by hour weather report from www.weather.com. I have found that deer use certain travel corridors to and from bedding and feeding locations based on the weather and wind direction. If you can connect a certain weather pattern to deer movement on your camera your half way home. Certain weather and moon phases can cause deer to use the travel corridors at different time of the day. Knowing these things can help to set up in the right spot at the right time.

Scrapes
written by JDaddy, June 26, 2009
I agree with most of that...But one thing that I differ on is that I do hunt scrapes alot these days and have good luck doing so. For years I hunted scrapes when I lived in Kentucky and the activity was really hit or miss over them. Sometimes you'd catch some bucks working them but 98% of the time you set there looking at the ground all day. I moved to Iowa 2 years ago and these deer are total opposites of southern deer. Iowa bucks will actualy use a scrap line during daylight hours when the rut is coming heating up. I watched bucks this past season cruising for an early doe and he would walk by a scrape, get down wind of it and catch a wiff then head right back to it and work it hard for 10-15 minutes. When he got done with that one he headed to the next one and repeated the process. Most of these scrapes are the big community scrapes and they will be hit by every buck in the area. Scrape hunting is alot like calling whitetails, it can be productive if the buck is in the right frame of mind. I've seen them walk right through a fresh scrape and never pause but then I've seen them thrash the crap out of licking branches and paw the dirt for long periods of time. I think it all depends on the mindset of that certain buck at the time he happens upon the scrape line. As far as tree rubs go, I never put to much stock in hunting them. Now if there's a rub line on a trail that's heavily used that's one thing but I dont purposely setup on a tree rub or rub line. I think it's another one of those things that has to do with the mindset of the buck, especialy in the pre-rut when they have bad attitudes alot of the time and just want to rip something up. They do use them to kinda mark "their" land but I dont think they are worth spending alot of time hunting cause 99.9% of the rubs you happen to find out in the deer woods are a one time thing, they wont revist most of them like they do scrapes. I have found community rubs before too where alot of bucks will rub one tree but the numbers of those arent even close to the number of scrapes you'll find that more than one buck will use.

Weather and State to State Differences?
written by CarrieZ, June 26, 2009
Toasteo: Fantastic idea!
I have a little notebook that I scribble observations in all the time, I never even thought about the parallels involving the weather. I am totally going to try that!

You are right, they are pretty sneaky and smarter than we give them credit for I think.

JDaddy: Couldn’t agree more, when I really started doing some research I realized how much time I was wasting hunting “rubs”. I was pretty mad, mostly at myself for taking one person’s advice without even questioning it.
Do you think deer differ greatly from one state to the next? The contrast between the IA and the KY bucks is pretty interesting.

Carrie, I use to say "A deer is a deer, they all have the same DNA" but after living in Iowa for a couple seasons now I think these bucks are a mutant breed, lol. Honestly the biggest difference between Iowa bucks and bucks in other states I've hunted is the pressure during the pre-rut & rut. Take my home state of KY, rifle season opens like the 2nd weekend of November, right when the rut is cranking up...That screws the rut up big time because of the added pressure of a flood of hunters hitting the woods wide open after a year of the deer being cool & calm. In Iowa we dont have to deal with gun season until Dec., well after the main rut has came and went...IA bucks get to be just that, bucks..They get to rut & run wild during Nov., they chase, they fight, the run scrape lines and believe it or not they actualy grunt, snort wheeze & roar at each other. In 3 weeks in Nov. my first season in Iowa I saw more rut activity than I did in 20+ years in KY. And honestly as far as numbers & land goes I had better places in KY to hunt than I do in IA. The other major difference in IA bucks compared to KY bucks is the ability to call them. Dont get me wrong I've called in alot of bucks in KY and other states over the years with grunts, bleats & rattleing horns but nothing like in IA...Come Nov. you hit a buck roar & throw a snort wheeze at a buck here in IA and he'll come in on a string, in KY they might come in or they might head towards the next county. These deer just respond to calls better than any I've ever hunted before. A PRIMOS Buck Roar call and my PRIMOS ScarFace Decoy are never far away come Nov. in Iowa, I know how well they will work here.
