Study Shows Worm Grunters Imitate Moles
Science_afficionado writes "In the southeastern US, fisherman have an unusual way to collect earthworms for bait. The practice is called worm grunting, fiddling, snoring, or charming. It involves pounding a wooden stake into the ground and rubbing the top of the stake with a long piece of steel to produce a grunting sound that causes earthworms to come to the surface where they can be easily collected for bait. A study published today in the open access journal PLoS ONE shows that the technique works because the worm grunters are unknowingly imitating the sounds created by burrowing moles. Full text of the paper is available at PLoS ONE."
it's not true what they say. The early bird doesn't get the worm. The stake does.
How did thid method originate?
I think that works for worms in more irradiated locations, but then you'll always be known as the 'worm-guy'.
I protest! I protest mightily!
If video games influenced behavior the Pac Man generation would be eating pills and running away from their problems.
But what do the earthworms do if not collected?
And, guess what:
Worms that were not collected began to burrow back into the ground after traveling some distance.
Damned, and i always thought that disgruntled grunted worms do a kind of lapdance. Puh, another dream not come true.
Worm sign detected.
If someone could just conjure up a way to imitate money and put that thing in a volcano or something we could make earth a better place in notime.

Think that no more. Nowhere* else in the world has worm charming become a national sport. With championships and everything.
For another laugh, watch the Sopchoppy Worm Gruntin' Festival. Yes. That's right. I said Sopchoppy. (hahaha, as well as the youtube vid, they have a page.
Man, I could go on & on, just search for worm grunting on google - fuck its funny.
* I await the inevitable, "we were first" replies from the old-worlders;)
making the sound of rain or water percipertaing and earth worms will (slowly) make their may to the surface to avoid drowning.
When I stick my spade in the ground to do a little digging, then the worms come crawling out too.
When I just stick it in the ground to and move it back and forth, even then the worms come crawling out. Probably due to the fact that friction of the spade with the ground creates other noises than only the thud from the spade.
YOU KILLED THE FLYING SPAGHETTI MONSTER!

It's been known for a long time that noises/vibrations bring worms to the surface. The only news here is that they're imitating the sounds created by moles (if that's really even true).
Even when I repot a plant in the garden and take it out of it's old pot and crumble the old soil mix away from it's roots the bits of soil falling off hit the floor and make worms come up because of the tapping sound of small objects hitting the floor presumably being much like the sound of rain hitting the floor.
I know this because the plants I repot are usually cacti and with the spikes resting on the floor and the rootball up in the air the worms have at times been dumb enough to come up underneath the cacti and ended up getting themself impaled on the spikes. I don't particularly like worms, especially ones I have to extract cactus spines from.
Thumpers have been known to work as well... (http://en.wikipedia.org/wiki/Thumper_(Dune)#T)
Birds step on the ground to make the same noise and where I come from they do it for ages.
...and potential legal problems with imitating money?
Just get a couple of adds... umm.. I mean articles... in the papers about lava bringing up diamonds and gold and oil and iPods to the surface.
At the same time take out another series of adds stating you will pay a premium for freshly hand-squeezed lava juice.
Follow that up with a series of adds about benefits of fresh lava to sex life and penis size.
Finally, take out another batch of adds for books and DVDs about the best ways and locations for lava collecting. Make those over the weekend and sell them for $29.99.
Once you get that thin rolling, hire someone else to keep the flow, get all your "data" about the booming "lava market" into a powerpoint presentation and find some investors.
Chanel their investments into personal accounts on Cayman Islands, personal bodyguards and campaign donations.
Oh yeah...
Profit.
Mit der Dummheit kämpfen Götter selbst vergebens
When i went fishing with my father we often got worms like this. He told me it represented moles. News at 11.
Better recipe:
take a metal pole
stick it in the ground (first!)
take a long (15ft) thick wire
wire the pole to a connector with one pin
stick that pin into the phase of your home ac
You'll see the worms jump out of the ground.
disclaimer etc: Of course you all are smart enough to pull the plug first and then collect the worms.
+1 funny
so we're treated to more&more "stuff that matters" stories about almost nothing from our 'mainstream' media. so, it's not just robbIE anymore.
into the ground and hit it a few times (softly) to get the same effect. This is old knowledge, so now suddenly a scientific paper comes out and makes this Nerd News ? Then I know a few more:
Next week in the headlines:
* water drains the other way if you're in Australia
* put a magnet near a needle and you can make a compass !
* your coffee will be warmer if you put in the milk *before* you walk to the door and return to drink it
Any more lessons ? Please add them to my post, I think we all have few.

Round here the seagulls pound the grass with their feet to attract worms
http://answers.yahoo.com/question/index?qid=20080126121505AA0f72V
We always got worms by sticking a rake or a shovel in the ground and shaking it. Even seagulls know the trick: they trample the ground with their feet. The worms are alarmed by the moving ground, thinking a mole is coming. They go to the surface and are grabbed.

My grandpa (Washington State / Kent, WA) used a pitchfork. Stick it in the ground and wiggle it very quickly.

Long live the Dead Milkmen! Or would that make them Undead Milkmen?
Different living things react to different things differently. That's nature. It's actually fun to observe, when you have time.
We did similar things to crabs too.
There is a kind of smallish crab living in the rice paddies. After harvesting season, we let the paddies to dry up. And those crabs would dig holes and live in there, to keep them wet and cool.
How do we get them? We dig the holes. But that's hard work, as some go as deep as one meter. And we were losing to our main competitor, some crab-eating egret. Those egrets could get the crabs many times faster than we could.
So, one day, we just sat there, watching how the egrets get them. We saw the egrets knock on the top of the hole with their beak or their foot, in certain frequency, and the crabs would just come out of their holes.
Ah hah, we just imitated the egrets, knocked on the hole too, and they came out. No more digging. I was nine.
Beware not to wake the big worms...
Hmm. The Island of Ireland (Hibernia) has no moles. But it has earthworms. Wonder have they evolved the same response or not.
I'd imagine so, since both burrowing mammals and earthworms have been around a looong time, but maybe then they might have evolved to lose the response?
water drains the other way if you're in Australia
This is actually a myth - it may be true for huge objects like weather systems, but the direction water goes down a drain is determined more by its shape.
I actually did an experiment with a friend in NZ to confirm this...
Also, hasn't just about everyone in the world seen a seagull doing a little dance to bring worms to the surface?

stuff science?
The technique works because they unknowingly imitate moles? What happens when they find out what they're doing?
I normally collect worms with a firewall and a good anti-virus program, but to each his own.
The technique [] reached its apex in the 1960's in Apalachicola when hundreds of people grunted for worms until the U.S. Forest Service began permitting the previously unregulated practice out of concern for the impact the industry was having on the native worm population.
So these Apalachicolan wormgrunters are such outlaws that they stop doing something once it's officially allowed? And the authorities are so smart that to stop a practice, they don't sanction but sanction it? Great system.
It's about wormholes, afterall.
Jumpin' Jesus on a pogo stick! Everyone knows that a burrow owl lives in a hole in the ground! Why the hell do you think they call them burrow owls anyway?
...for the two and a half slashdot readers who like worms.
Doesn't it make you feel good to know that our freedoms are protected by politicans, lawyers and journalists.
We have wormsign the likes of which even God has never seen!
There are no moles here. I wonder if the mole impersonating trick works here... I'll have to find out.
If the worms are indeed fleeing what they believe are burrowing moles, I wonder if the technique would work in places where moles do not exist?
In Australia for instance, we have plenty of earthworms, including the world's largest (which grow up to three metres long) yet we have no native moles. Logically you would expect the worms not to react, but perhaps worms in Australia would be trying to flee bandicoots or bilbies.
The thing is I don't know whether bandicoots or bilbies sound like burrowing moles. Perhaps you would need a smaller stake, or a longer saw. Could be an interesting experiment though.
If the pattern goes 9am, 10am, 11am, why isn't noon 12am?
Yes! The wurm is the spice! The spice is the wurm!
Look into that dark space that you so fear to look and you will see ME staring back at you!
Case closed .....
Its not the years, its the mileage
If the worm grunters learn about the results of this study, will the technique stop working?
