I enjoy blinkist a lot but there are a lot unscientific topics e.g. against vaccines.

My bet, the ultimate answer is just going to be something like: "Yeah, there's some padding and stuff, but they still give themselves concussions and then they just deal with it"

Their beak is quite sharp, so it might not be like hitting a rock, but rather a softer impact as the beak tip pushes its way into the wood.

What about woodpecker tongues? I vaguely remember that being part of a protection system.

Sci show has a tendency to make mistakes like this as each video is based off 1 or 2 papers not broad research, you are correct there tongues wrap the head inside a tendon like sheath to act as a brain shock absorber.

The tongue does wrap around the skull and is theorized for shock protection

I think rams ramming eachother at full force look far more painful, I am always amazed that they are built to handle that without injury.

A woodpecker (yes, I do think it was the same one) used to show up in my yard and pound on either my bird feeder or the down-spout of a gutter, both which are made of metal, and he would go at it for hours, never learning he wasn't making any progress except chipping the paint. He always returned to attack the same spot on each.

If you're thinking they avoid pecking things that are "not too stuff", you can throw that idea out. I can assure you woodpeckers are happy to peck repeatedly, day after day, on metal towers. Either they used the reverberating "clang-clang-clang-clang-clang" to communicate, or they just like the sound/feeling of it.

they also use their long tongues which wrap around their brain to cushion shockwaves

I've been secretly hoping that a photo I upload to Wikimedia Commons gets used in a SciShow video for literally years, and look at 0:50 , that's my photo. For those wondering, this is a Pileated Woodpecker (Dryocopus pileatus) skull with the sclerotic ring (eye bones) and rhamphotheca (keratinous part of the beak) removed. The photo was taken in the Osteology section of the Smithsonian National Museum of Natural History in Washington.

Wonderful video! I have spent lots of time watching woodpeckers and they are pretty special birds.

I find it strange that the whistle like shape of the skull wouldn't tip someone off that some resonance braking was occurring. Like, if the pressure wave is transferred along the lower jaw to the back of the skull, it stands to reason it would continue around the skull into that spongey area. If the acoustic properties of the skull are right, that travel time might be just right to set up a sympathetic vibration to dampen internal vibrations without actually absorbing any of the shock, as the wave would then travel down instead of around. But that's just me.

OMG! THEY'RE LIKE HAMMERHEAD BIRD-SHARKS!!

yeeees thank you for making this one

Great video!!! ❤

Woodpecker pecking my window frame into a mess is what I'm more concerned about..

After recently rewatching sci show psych compilations on the brain, one has to wonder how much woodpecker brains might be able to teach us about chronic head trauma. Do they have the same systems in place that we do serving different purposes, such as microglia? What could they teach us about disorders like CTE? Do old woodpeckers eventually develop something resembling CTE? If not what biological processes have they evolved to have become resistant to such problems?

Research has shown that woodpecker brains do in fact show signs of injury and produce proteins similar to humans with dementia and degenerative nerve diseases. Woodpeckers just don’t seem to suffer any adverse effects from these injuries, though. We have yet to determine why this is the case, though.

I think the jaw hypothesis makes the most sense, since you can pack in a lot of cushioning tendons and neck muscles behind a jaw bone. I do wonder if the mammalian jaw/gill/ear evolution prevents mammals from doing something similar.

They are simply rubbing together brain cells manually. Smartest creatures on earth

I've seen a recent article suggesting that they have a really long tongue which wraps around their skull to some extent. Which adds padding, basically.

What about that woodpecker that frequently gets going on my gutter's downspout? Does the beak to metal action cause problems and WHY does the wacky thing go nuts on the metal pipe?!

why would woodpeckers then peck at metal chimney pipe? had one that would go nuts for hours every day in spring .

Maybe, the brain isn't in the head, but other part of the body 🤣🤣🤣

Head bangers 🤘💀

i wonder if pecking chickens have spongy bones in the skulls also

Strong head 👍

That woodpecker video looks exactly like a jackhammer

Cutely pecking away

i was told their toungues wrap around their skull and act as padding ah the 90's

Maybe John could ask the ones outside his house if they get concussions?

The Hammered Woodsniper

Ooh yea I see and hear them all the time 😖😱

I have never seen a woodpecker before, besides on tv and internet

Used to have a woodpecker try and drill thru a transformer outsode our house. Went on for years. Then the transformer got blown up in a storm. He didnt like the new one and stopped pecking at it.

I remember reading an article which said woodpecker brains display injuries and chemical signatures that are similar to Alzheimer’s and other degenerative nerve diseases in humans. For reasons we have yet to determine, though, they simply do not suffer adverse effects like humans do.

My bet would be that woodpeckers have sophisticated systems of fluid, ventricles, and flow pathways that use pressure to slow their brains and keep them from impacting the inside of the skulls, as well as the other adaptations they possess.

Kinda like a combination hammer and chisel. I wonder if they master exiting that resonance stage with more difficulty than entering it; in similar vein to the mastery of accelerating powerful machinery being much easier than (subsequently) slowing and halting it without succumbing to detrimental jolting and vibrations.

They tongue wrap from the back to the front like a spring mechanism or something

You might say their skulls are... Built Different!

So in the little animated clip talking about the jugal bone (3:06), it showed the direction of the equal and opposite force went. When I saw that, I thought, "What if, along with the bit of spongy bone, that is what helps keep the birds brain safe?" So, here's my hypothesis: With all the data presented here along with the question as stated above, I believe that could be enough to help keep the brains of woodpeckers safe.

Did none of these studies look at the tongue, which continues back, between the horns of the hyoid bone, and then wraps around and attaches to the sagittal crest at the top of the skull? The tongue sloshes around so the brain doesn't have to. Wasn't that the subject of your previous woodpecker video?

Interesting, in eastern Europe as a kid (15-20) years ago, I was told that the mehanism behind not getting concussion was completely different. I was told that brain is smaller thant cavity, it was "hanging" on elastic "strings" and floating in some kind of liquid. Those two elemnts would work as dampened spring and help prevent concussion. It would be interesting to know if anyone had heard something simmilar?

It really helps too that woodpecker brains are just really small and don't have much in the way of mass to decelerate. Human brains are far larger and more fragile

If a woodpecker could talk, it would sound like Hershel Walker?

I'm wondering, isn't there really any studies done on the mechanics and physiology of the woodpeckers' pecking? I'm very surprised that in this day and age we still don't have a solid answer on this question but only speculations of various kinds. Where have the ornithologists been on this vlog??

It would be interesting to have a complex species to evolve having its brain be located somewhere besides the head. Guess that would be a bit much, though it would be rather interesting.

Looks like the inverse square law also work here. The strength of the material is proportional to the square of the diameter but the mass is dependent on the volume of the object and thus proportional to the cubic of the size. Woodpeckers have the brains just small enough to survive the shock with enough cushioning. Human brains are simply too heavy for that.

it seems the esophagus part for the most of time can send it far back quickly without most of the outer portion being dissolved in the proximal gastric, but as we see the huMAN fails, it consumes and as the allergic reaction increases and not reduces in a different site and white blood cells cause a cold shock and you know what that systemically will do in the longer duration of not being solved.

I specifically feed the flickers to keep them around as much as possible. I love to watch them eat the bugs off of my sunflowers.

this made me think of baki and their wobbling brain science

In Arizona and other parts of the southwest we had to deal with these little idiots banging their beaks on our chimney covers. My Dads theory was they liked how loud it made them sound. My Brothers theory was they never learned becuse they kept self-concussing.

if a woodpecker could peck a wood, how many woods would a woodpecker peck if woodpecker could peck a wood?

Could you make a human head explode by tuning into that frequentie using sound?

I'm going to debate the argument that they peck soft woods because there are woodpeckers in my building that peck the metal pipes to get bugs to come out.

I’m just going to go old school ‘scientist’ on this and say, “Clearly woodpeckers’ brain are not in their heads, but in their rears, as if it were in their head they would immediately concuss themselves to death. It is likely that all birds’ brains are actually in their rears, and that this was evolved long ago even before they split from dinosaurs.”

If they have a higher viscosity cerebral spinal fluid it would slow down brain movement as well.

SciShow continues to be foolish by giving God the credit for creating such an amazing creature! Behind every object, there is a design. Behind every design is a designer!

All the reasoning is how the skull is adapted. How is the brain adapted to this? A brain moving back and forth in a well protected skull would still mean injury!

Maybe they just feel what works for them and respond appropriately. In time much like us they will adapt appropriately… though much like them we slam things and adapt where we can

What about this, if you took an ant and flicked it off your kitchen counter, it gets up and runs away. It doesn't die, it doesn't get stunned or paralyzed. I imagine if you took an ant and dropped it from 1000 ft up in the sky, same thing. Whatever is going on with that ant and my guess is its weight related, is probably the answer to how much wood a woodpecker can peck as a woodpecker pecks much wood.

What if… woodpeckers just had no brains?

Yes

Fun fact: Male woodpeckers attract girls by showing off how big and strong their pecking game is. This is why you'll find woodpeckers having at it at steel gutters, because that makes a lot of noice. And why you'll find woodpeckers cutting a tree in two, because during mating season the males peck wood until they either get laid or die of exhaustion.
