Transcript
- 0:01Speaker 1: Welcome to the Wired2Hunt Foundations podcast, your guide to the
- 0:05Speaker 1: fundamentals of better deer hunting. Presented by First Light, creating proven,
- 0:10Speaker 1: versatile hunting apparel for the stand, saddle, or blind. First Light,
- 0:15Speaker 1: go farther, stay longer. And now, your host, Tony Peterson.
- 0:20Speaker 2: Hey everyone, welcome to the Wired to Hunt Foundation's podcast,
- 0:22Speaker 2: which is brought to you by First Light. I'm your host,
- 0:25Speaker 2: Tony Peterson, and today's episode is all about scrapes. Why
- 0:27Speaker 2: do you make them? Why they use them? And why
- 0:30Speaker 2: they might be your best bet for a mature buck
- 0:32Speaker 2: right now. We're getting into the heart of the bow
- 0:35Speaker 2: season here across the country. Things are heating up out there. Now,
- 0:38Speaker 2: even if your cameras don't really show it yet, more
- 0:40Speaker 2: and more buck sign is showing up by the day.
- 0:43Speaker 2: And while a lot of us have our hearts set
- 0:45Speaker 2: on getting out there like the last week, October, missing
- 0:47Speaker 2: this time window right now is a mistake. This is
- 0:50Speaker 2: one of the best times to scout for scrapes and
- 0:52Speaker 2: then hunt scrapes. And this isn't just my opinion, although
- 0:55Speaker 2: I do believe it. It's also what the deer science says.
- 1:03Speaker 2: In a past life, I lived in an apartment on
- 1:05Speaker 2: a lake in north central Minnesota working as a magazine editor.
- 1:08Speaker 2: I was sort of on an island at that point
- 1:10Speaker 2: in my life, very far away from my wife and
- 1:12Speaker 2: my friends and pretty much anyone who I cared about.
- 1:15Speaker 2: So I did what anyone would do. and hunted and
- 1:18Speaker 2: fished like an absolute fiend. I was in a place
- 1:21Speaker 2: with a lot of outdoor opportunities, and I had a
- 1:23Speaker 2: boat and a few places to deer hunt, and, well,
- 1:25Speaker 2: I went pretty hard. And I remember a particular evening
- 1:29Speaker 2: up there on October 20th where I saw two bucks
- 1:32Speaker 2: working through the woods toward my stand. One was a forky,
- 1:36Speaker 2: but the other was a two-year-old type of eight-pointer, and
- 1:38Speaker 2: he was plenty big enough for me at the time.
- 1:41Speaker 2: I watched both bucks as they ate acorns and meandered
- 1:43Speaker 2: in my direction, but the bigger of the two bucks
- 1:45Speaker 2: would stop fairly often, make a quick scrape, and then
- 1:48Speaker 2: just keep moving. I remember thinking that those scrapes didn't
- 1:51Speaker 2: look like they meant a thing to him. It was
- 1:53Speaker 2: like watching someone who is obsessed with golf take practice
- 1:56Speaker 2: swings with an air club while disengaging from conversation. Now
- 2:00Speaker 2: I went on to miss that buck clean at about
- 2:02Speaker 2: 20 yards due entirely to buck fever and not being
- 2:05Speaker 2: able to keep my shit together. Fast forward from that
- 2:08Speaker 2: hunt a handful of years, and you can get to
- 2:10Speaker 2: a night in mid-October where I again watched two bucks together.
- 2:13Speaker 2: This time, the bigger deer was pushing Pope and Young,
- 2:16Speaker 2: and since he was on public land in the Twin Cities,
- 2:19Speaker 2: I really wanted to shoot him. Both of those bucks
- 2:21Speaker 2: made scrapes on a field edge, and both of the
- 2:24Speaker 2: scrapes they made, they just felt like they had a
- 2:26Speaker 2: different vibe. I don't know how to describe it, but
- 2:29Speaker 2: I felt like those bucks would come back. So the
- 2:31Speaker 2: next night, despite it being October 15th and really hot
- 2:35Speaker 2: and windy, I carried a stand in there and set
- 2:37Speaker 2: up over the bigger buck's scrape, which I had marked
- 2:39Speaker 2: by a pine tree that he was raking his antlers in.
- 2:42Speaker 2: He was the first deer I saw after he emerged
- 2:44Speaker 2: from a cattail slew, and eventually he walked right into
- 2:47Speaker 2: that scrape and offered me a wonderful 7-yard shot. Now,
- 2:52Speaker 2: I don't say this to brag, but to illustrate a point,
- 2:54Speaker 2: I also killed a great 10-pointer in Illinois during that
- 2:57Speaker 2: time period who was working up a scrape on like
- 2:59Speaker 2: November 11th, and also a really good 11-pointer in Nebraska
- 3:03Speaker 2: who was working a scrape on November 8th. I don't
- 3:06Speaker 2: say that to muddy the waters any, but to highlight
- 3:08Speaker 2: that you don't only have one option to hunt scrapes.
- 3:11Speaker 2: They can produce, you know, from now until the season
- 3:13Speaker 2: closes in many places. But that doesn't mean they'll be
- 3:16Speaker 2: as attractive to the deer at other times as they
- 3:18Speaker 2: are now. A recent study conducted in Tennessee by researchers
- 3:22Speaker 2: who monitored 107 scrapes for a total of almost 7,400
- 3:27Speaker 2: camera trap days found that scrape activity peaked during the
- 3:31Speaker 2: first half of November down there, immediately before the beginning
- 3:34Speaker 2: of the rut. And then activity declined pretty quickly as
- 3:37Speaker 2: the rut progressed. They parsed that data out over 3,000
- 3:41Speaker 2: scrape visits, which is kind of wild. Now you might
- 3:44Speaker 2: be thinking, well, then why wouldn't I wait until November
- 3:46Speaker 2: to sit scrapes? And that is a great question. They
- 3:49Speaker 2: observed peak scrape activity right before the rut really hit
- 3:53Speaker 2: down there, which means it had been building up for
- 3:56Speaker 2: some time. I kind of think about it this way.
- 3:59Speaker 2: You might have more chasing on November 7th than you
- 4:01Speaker 2: would on October 27th. but that doesn't mean you don't
- 4:03Speaker 2: want to catch the first wave of chasing. Now maybe
- 4:06Speaker 2: that's not enough to convince you to hunt scrapes right now,
- 4:08Speaker 2: so consider this. There's a lot of research on scrapes,
- 4:12Speaker 2: and the primary findings across the board are that scrapes
- 4:16Speaker 2: are places where deer advertise and investigate reproductive conditions, social status,
- 4:22Speaker 2: other deer's individual identities, and the sex ratio of the area.
- 4:27Speaker 2: Does use them, little bucks use them, and great big
- 4:30Speaker 2: mature bucks use them. And what they are is more
- 4:34Speaker 2: than a big buck's chance to paw up some dirt,
- 4:36Speaker 2: rub his forehead on a licking branch, and advertise that
- 4:39Speaker 2: he is there and ready for the ladies. It's so
- 4:42Speaker 2: much more nuanced than that. This is where we can
- 4:44Speaker 2: do an interesting little thought experiment. So we think about
- 4:47Speaker 2: the rut and phases, and we hunt according to those phases.
- 4:50Speaker 2: What we don't think about is that all of the
- 4:53Speaker 2: deer out there, does and bucks, are already well established
- 4:56Speaker 2: into their hierarchies. and they are well-versed in the most
- 4:59Speaker 2: desirable mates to produce offspring, you know, which are the
- 5:03Speaker 2: healthiest mates they can find. Does don't really have blind
- 5:07Speaker 2: dates a whole lot. They know who is around, and
- 5:10Speaker 2: they know who is the best bet to produce strong
- 5:12Speaker 2: and healthy offspring. They have been smelling individual bucks in
- 5:15Speaker 2: their sign for a long time, with increased frequency in
- 5:18Speaker 2: the days leading up to the rut. This isn't an accident,
- 5:21Speaker 2: and it's probably not nearly as random to them as
- 5:24Speaker 2: it appears to us. If a buck wants his chance,
- 5:28Speaker 2: and he does, he needs to make the does aware
- 5:30Speaker 2: of his presence and his prowess. And he can communicate
- 5:34Speaker 2: a hell of a lot of that through scent. But
- 5:36Speaker 2: his scent communication is deeper and more nuanced than we
- 5:39Speaker 2: often think as well. So for starters, a buck's going
- 5:43Speaker 2: to paw up the leaves to get to the bare dirt.
- 5:44Speaker 2: But why? Well, bare dirt's more absorbent than leaves and sticks.
- 5:49Speaker 2: It holds the scent longer. You know, when he pees
- 5:51Speaker 2: in it or pees down his legs to gather scent
- 5:53Speaker 2: from his tarsal glands. But that's not all, though. Deer
- 5:56Speaker 2: also have interdigital glands on their feet that contribute to
- 5:59Speaker 2: the scent signature on the ground. He isn't digging a
- 6:02Speaker 2: hole and just exposing bare dirt to pee in. He's
- 6:05Speaker 2: also actively leaving scent from those glands. He'll also rub
- 6:09Speaker 2: his preorbital forehead glands on licking branches as well. He'll
- 6:13Speaker 2: chew on it, he'll lick it, rub his antlers on it.
- 6:16Speaker 2: He's leaving as much viable information as he can. Now,
- 6:19Speaker 2: when I was a young deer hunter full of piss
- 6:20Speaker 2: and vinegar and almost no deer hunting skills, the common
- 6:23Speaker 2: thought around scrapes was that they were made by a
- 6:25Speaker 2: big buck and that was that. He made it and
- 6:28Speaker 2: he might come back or he might not. We didn't
- 6:30Speaker 2: have trail cameras then, and we didn't have nearly as
- 6:33Speaker 2: many deer around as we do now in a lot
- 6:35Speaker 2: of places. But mostly, we just didn't have as much
- 6:37Speaker 2: good information on deer behavior. Now we know that scrapes
- 6:40Speaker 2: don't quite work that way. One study conducted in the
- 6:43Speaker 2: early 2000s found that as many as 13 different bucks
- 6:46Speaker 2: visited one scrape. Some scrapes they monitored were worked up
- 6:50Speaker 2: by at least nine different bucks. That might seem like
- 6:53Speaker 2: two connected but disconnected pieces of information. But what they
- 6:57Speaker 2: also found out was that a lot of the bucks
- 6:58Speaker 2: that visited scrapes didn't add any of their own scent.
- 7:02Speaker 2: They just checked out the olfactory info left there by
- 7:05Speaker 2: the other members of the herd, but didn't add any themselves.
- 7:08Speaker 2: They also found that does actually visited scrapes a lot,
- 7:12Speaker 2: but that bucks exhibited much more marking behavior. But why
- 7:15Speaker 2: would does visit scrapes a lot? Remember what I said
- 7:18Speaker 2: about them trying to pick the best mate to produce
- 7:20Speaker 2: the strongest and healthiest offspring? Think about it this way.
- 7:23Speaker 2: In almost all courtship rituals from butterflies on up to
- 7:26Speaker 2: us people, there's usually a finding out period where two
- 7:29Speaker 2: potential mates get to know each other. Sometimes that's a
- 7:32Speaker 2: short period of time, sometimes not. But when it comes
- 7:35Speaker 2: to selecting someone to produce offspring with, at least intentionally,
- 7:39Speaker 2: there's usually some care and planning and thought and, well,
- 7:43Speaker 2: decision making. You don't really wanna produce offspring with someone
- 7:46Speaker 2: who isn't a very good example of your species, I
- 7:48Speaker 2: guess you could say. That study I just mentioned found
- 7:51Speaker 2: that of the 3,000 interactions with scrapes, about a quarter
- 7:54Speaker 2: of them were from does. Some does lick the licking
- 7:56Speaker 2: branch and paw off the dirt, but most just go
- 7:59Speaker 2: around and sniff up some information. I think we can't
- 8:12Speaker 2: begin to really understand what that information is like to
- 8:15Speaker 2: take in, though, because we just don't have their scenting capabilities.
- 8:19Speaker 2: Research has shown that deer scent glands produce numerous chemical
- 8:22Speaker 2: compounds that vary with sex, age, dominance, and hormonal state.
- 8:27Speaker 2: It's so much more than just, a buck was here.
- 8:30Speaker 2: They are truly evaluating potential mates. Now, to take this
- 8:34Speaker 2: a step further, just think about the licking branch. For starters,
- 8:37Speaker 2: if you find a scrape that doesn't have a licking branch,
- 8:40Speaker 2: you might as well not hunt it. It's that important.
- 8:42Speaker 2: A licking branch allows deer to leave saliva and scent
- 8:45Speaker 2: from their forehead and preorbital glands, resulting in a multi-layered
- 8:49Speaker 2: chemical message that contains a lot of information. Scrapes are
- 8:53Speaker 2: important to deer, and they should be important to deer hunters.
- 8:56Speaker 2: That Tennessee study found that the scrape activity ramped up
- 9:00Speaker 2: in mid-November. They also found that peak breeding happened in
- 9:03Speaker 2: early December in that region. So scraping got hot and
- 9:07Speaker 2: heavy about two to three weeks before peak breeding. If
- 9:10Speaker 2: you're in the upper Midwest, that means now or very soon.
- 9:14Speaker 2: If you're down south, you might have a month or
- 9:16Speaker 2: more to wait out before this hits. But the key
- 9:19Speaker 2: is to understand that this is a strategy that can
- 9:21Speaker 2: work no matter where you hunt, as long as you
- 9:24Speaker 2: understand scraping and its connection to peak breeding. So that
- 9:28Speaker 2: makes it seem straightforward. But with anything nuanced, there's always
- 9:32Speaker 2: a catch. And the catch with hunting scrapes is that
- 9:35Speaker 2: most of the visits happen at night. A study in
- 9:38Speaker 2: Georgia found that 85% of buck visits occurred after dark,
- 9:42Speaker 2: and 75% of doe visits occurred after dark. That Tennessee
- 9:47Speaker 2: study showed that two-thirds of all visits to scrapes occurred
- 9:50Speaker 2: during the time when the vampires are out. That's not
- 9:53Speaker 2: great news for anyone who only hunts during legal shooting hours.
- 9:56Speaker 2: This is one of the reasons that hunting scrapes is
- 9:59Speaker 2: so frustrating. It's very easy to blank when you hunt scrapes,
- 10:03Speaker 2: even community scrapes, which are a thing. The right scrape
- 10:06Speaker 2: is a social networking spot for the deer, and finding
- 10:10Speaker 2: a scrape in a hub of activity during the window
- 10:12Speaker 2: when deer should most likely be using it is one
- 10:15Speaker 2: of the best bets for actually killing a big buck
- 10:18Speaker 2: on a scrape. When you pair those details with, say,
- 10:21Speaker 2: a cold front or a crisp morning after it has
- 10:25Speaker 2: rained all night, then you have something that is primarily
- 10:28Speaker 2: visited at night that is far more likely to be
- 10:30Speaker 2: visited during the day. The lesson here can't be overstated.
- 10:35Speaker 2: Hunters are good at taking seasonal timing and then some
- 10:38Speaker 2: tactic and combining them because they should work. I don't know,
- 10:41Speaker 2: like a lot of hunters think that rattling during the
- 10:43Speaker 2: rut is the move because it's November 10th and all
- 10:45Speaker 2: the bucks should be out actively looking for does and
- 10:47Speaker 2: ticked off at all their rivals. but what if it's
- 10:50Speaker 2: 75 degrees and you expected it to be 30? Or
- 10:53Speaker 2: what if you have nine deer per square mile and
- 10:55Speaker 2: only three of those are bucks? Do you expect them
- 10:57Speaker 2: to go running into an area where they suddenly hear
- 10:59Speaker 2: two new big sounding bucks going at it? What if
- 11:03Speaker 2: they figure most of their squabbles out by the end
- 11:05Speaker 2: of October and they just don't want to risk an
- 11:08Speaker 2: injury or burning a bunch of calories by November 10th?
- 11:11Speaker 2: The thing about good deer hunters is that they are
- 11:13Speaker 2: pattern matching machines, which is really the key to most
- 11:17Speaker 2: predatory success in nature. While it might be October 17th
- 11:20Speaker 2: and theoretically a good time of the season to hunt scrapes,
- 11:23Speaker 2: your job isn't just to find a scrape and hunt it.
- 11:26Speaker 2: Your job is to find the right scrape, a community scrape,
- 11:29Speaker 2: which will be in the cover most likely, and then
- 11:31Speaker 2: hunt it when the weather conspires to get bucks moving
- 11:33Speaker 2: in daylight. That Tennessee study found that an average of
- 11:37Speaker 2: 12.2 bucks visited each scrape, and that anywhere from 1
- 11:41Speaker 2: to 39 bucks monitored individual scrapes. Bucks visited an average
- 11:45Speaker 2: of 5.9 scrapes apiece. That is an enormous amount of
- 11:49Speaker 2: information being collected and tells you another thing about strategy.
- 11:53Speaker 2: If he doesn't visit the scrape today, it doesn't mean
- 11:55Speaker 2: that he's not going to tomorrow or when the conditions
- 11:58Speaker 2: get better at the end of the week. But if
- 12:00Speaker 2: he's been on camera or you've seen him hit a scrape,
- 12:03Speaker 2: the odds are pretty decent he will hit it again.
- 12:06Speaker 2: And here's another thing to think about. Bucks don't make
- 12:09Speaker 2: scrapes randomly and then hope does and other bucks show
- 12:11Speaker 2: up and visit them. They make scrapes along established movement routes.
- 12:16Speaker 2: This is one of the reasons I love rub lines, too.
- 12:19Speaker 2: Bucks make sign where they like to travel, which is
- 12:21Speaker 2: them tipping their hand to us in a major way.
- 12:24Speaker 2: Scrapes function best when lots of deer encounter them. Immature
- 12:28Speaker 2: bucks know that. They make scrapes where they have the
- 12:30Speaker 2: highest odds of deer visiting them. It's kind of like
- 12:33Speaker 2: if you, I don't know, bought a food truck and
- 12:35Speaker 2: parked it on a dead-end street in a run-down neighborhood
- 12:37Speaker 2: versus at a bustling shopping center downtown where concerts happen
- 12:41Speaker 2: all the time. There's a row of restaurants and bars
- 12:44Speaker 2: and maybe a sports stadium two blocks away. I guess
- 12:47Speaker 2: one last point I want to make that the research
- 12:49Speaker 2: supports is that fresh matters when it comes to scent.
- 12:53Speaker 2: This is intuitive, of course, and very likely the reason
- 12:56Speaker 2: bucks hit scrapes hard after it rains. The difference is
- 12:58Speaker 2: simply someone was here versus someone is here. And the
- 13:02Speaker 2: buck wants all of the does and all the subordinate
- 13:04Speaker 2: bucks to know that they are there now. Okay, so
- 13:08Speaker 2: that's a lot of information. But what do you do
- 13:10Speaker 2: with it? You can run cameras on scrapes and you'll
- 13:13Speaker 2: learn a lot, trust me. but you'll also be hunting
- 13:16Speaker 2: sort of retroactively versus proactively with just a camera-based strategy.
- 13:21Speaker 2: If you get a video of a 150 in shooting
- 13:23Speaker 2: light on one of the community scrapes on your lease, great.
- 13:26Speaker 2: But he's not guaranteed to show up the next day
- 13:28Speaker 2: or even in the next week. You want to be
- 13:30Speaker 2: there when he visits that scrape. This involves getting off
- 13:33Speaker 2: the field edges, looking for big scrapes with licking branches,
- 13:37Speaker 2: and figuring out how to hunt them right now. It's
- 13:39Speaker 2: honestly one of my favorite things to do for a
- 13:41Speaker 2: couple of reasons. The first is that it's still a
- 13:43Speaker 2: little early for tons of people to hit the woods.
- 13:46Speaker 2: The rut isn't even close enough yet to draw the masses,
- 13:50Speaker 2: which is important if you hunt pressured ground. The second
- 13:52Speaker 2: is that when you get into cover and find a
- 13:54Speaker 2: community scrape, and then you look at the 10-day forecast,
- 13:57Speaker 2: you can pick and choose conditions that should promote deer
- 14:00Speaker 2: activity in a very specific spot at a very specific time.
- 14:04Speaker 2: You might only get two or three weather windows where
- 14:06Speaker 2: the odds are highest, but if you do, you had
- 14:08Speaker 2: better use them to the best of your abilities. And
- 14:11Speaker 2: I'll say this as well. I'm of the opinion that
- 14:13Speaker 2: less is more when it comes to deer hunting and gear.
- 14:16Speaker 2: While you might be tempted to go blind call while
- 14:18Speaker 2: hunting a scrape or dump a bottle of estrus dopey
- 14:21Speaker 2: in it to ensure that all the neighborhood bucks will
- 14:23Speaker 2: lose their minds and run into your setup, I go
- 14:25Speaker 2: the other way with it. Once you understand why deer
- 14:28Speaker 2: make scrapes and why they use them, it's a lot
- 14:30Speaker 2: easier to put your faith in that, you know, just
- 14:32Speaker 2: being enough to get them to come into your location.
- 14:35Speaker 2: I'm not saying I wouldn't call to a buck that
- 14:37Speaker 2: I saw but I didn't think he was going to
- 14:38Speaker 2: come in or whatever, but even then, that makes me
- 14:41Speaker 2: a little nervous. When I've intentionally hunted scrapes this time
- 14:44Speaker 2: of year in my neck of the woods, I've found
- 14:46Speaker 2: that they often take their time getting to a scrape.
- 14:49Speaker 2: They're usually just kind of meandering around in the cover,
- 14:51Speaker 2: you know, browsing, maybe making a rub, just kind of
- 14:54Speaker 2: hanging out. But they usually get there. And I don't
- 14:57Speaker 2: really want to make contact with him until I truly
- 14:59Speaker 2: believe they won't come in before I have to be
- 15:02Speaker 2: done for the night or the morning. It's a hard
- 15:04Speaker 2: thing to do, especially if you haven't killed a few
- 15:06Speaker 2: big ones off of scrapes or at least seen the
- 15:08Speaker 2: whole thing play out the way it's supposed to. The
- 15:10Speaker 2: only way to get there is to try. And this
- 15:12Speaker 2: is the time of the season to try it. So
- 15:14Speaker 2: get out there, find the right scrape, plan your setup accordingly,
- 15:18Speaker 2: and then watch that weather. It only takes one morning
- 15:21Speaker 2: or one evening to really show you what a scrape
- 15:23Speaker 2: can mean to the deer and to us as deer hunters.
- 15:26Speaker 2: So do that and come back next week because I'm
- 15:28Speaker 2: going to talk more about pre-rut hunting tactics. That's it
- 15:32Speaker 2: for this week. I'm Tony Peterson. This has been the
