Today, we’re in Shawnee,
Oklahoma,where they’ve got some eagles,
hawks, even hummingbirds.
He’s gonna do
what we call rousing. It means he’s very happy right
now, so he must like you two. – Why have you never roused
for me?
– Sorry. – Gav:Look at that.
So weird.

– Dan:Wow.And action, hummingbirds. – Go on, son.
– Gav:Whoa, look at that.Oh, whoa.
– Dan:Oh, he is just not
happy about it.
Gav:Dive-bombs him.That was wicked. I really like filming animals
at work. I mean, it’s just the best
subject for me to film. It’s always stressful though because you never know
if a bird’s gonna perform. You can’t exactly tell
an animal to do something and expect it to do it.A slow mo rouse.You know, I love
depending on animals to do what we want them to
exactly when we want
them to. Maybe if we turn around,
pretend we’re not looking. ( chuckles ) – Go on.
– Look at his feathers. Gav: I got it. It’s funny how different birds
have different methods
of flying. Like an eagle can just soar
and maybe flap once a minute
or something if it has to. But then a hummingbird
to stay where it is needs to flap however
many times it is a second. Yeah, well we filmed both
on the Phantom, so why don’t we go over
to the screen and compare ’em. Okay, so I brought up–
it’s probably one of our
very first shots of the day. But supposedly the hummingbird
beats its wings the most times
in a real time second
on this clip. So, what we’ll do,
we’ll count the wing beats until it’s displaying
one second. I like that we have to have
that small of a unit
of time. Yeah, I mean, you do.
It’s slow mo footage. – All right, ready.
– All right, count.( music playing )One.
That’s two. Yeah, now it’s on three. This is three right now. – That was three.
– This is three, yeah. Okay. Now this is four. Four.
We might have to speed this up.( music playing )Gav: All right,
that’s one second. – 48.
– Well, uh, it’s sort of
47 and a half ’cause it’s sort of
half way. Oh, sorry, hold on.
Yeah, uh… – There we go.
– That’s right, you’re not
getting all the credit. ( laughs ) Only 47 and a half? In one real time second. That is really fast. It doesn’t seem that amazing
when you’re watching it
back on slow-mo. I mean, are you saying
that our slow-mo made him
less impressive? – Yeah.
– ( laughs ) – Yeah, exactly.
– How many flaps could
you do in one second? – Three?
– Maybe? – An entire flap?
– What does that look like? ( laughter ) Okay, this is good
information. So now we know that. Why don’t we now compare
the footage to the footage of
the hawk that we have. We’ll have to speed
this up – to match the hawk.
– All right. – Yup.
– That’s two different
worlds right there. – Yeah.
– ( laughs ) It’s kind of unfair
because the hummingbird is about the size
of that one’s beak. Yeah, you’ve got to remember
that this is actually like this big. Also, they completely flap
their wings in a different way. Like the hawk bends
its wings halfway and it’d be kind
of difficult. That one just has
straight wings. The hummingbird just
does this. It looks like he’s getting lift
on his backstroke, too. Whereas this one,
he doesn’t have to
worry about it. – He’s kind of just
enjoying the glide.
– Both of those can fly, but they’ve got two completely
different ways of doing it. I think we should learn
a little bit more. All right.
Hey, Peter,
thanks for coming on. Hey, thanks for having me.
It’s great to be here. Dan: So we’re with
the hummingbird expert, so, I don’t know much
about birds. I’m hoping you could
enlighten us. – I’m happy to do it.
– Yeah. So we’ve just counted 47 and
a half wing beats per second. – I think we should round ’em
up, I think he got 48.
– He doesn’t deserve it. – All right, all right.
– He didn’t work hard enough
for that. So is that average,
or is it usually
they get more? That’s right about
in the middle of the range. So normally, between about
40 and 60 beats– strokes per second. One other thing I noticed
is that it seemed like they were getting lift
on their forward flapand the back swing,
is that right?
Peter:They’re the only
birds to do that.
Dan:The only birds to do it?Peter:Yeah, and they do that
because they’re able
to flip their hand over. It’s basically their wrist
going back and forth.So it’s able to get lift
in both directions
which is–
it still has the same stroke,
forward and backwards
that another bird does,
but it’s flipping
and able to get lift
in both directions.
They’re the only bird
I’ve seen where in real time I can’t always see the wing.
‘Cause it just looks like– Peter:Well, they’re the fastest
stroke of any animal.
I also like the fact
that it’s named after
what it sounds like. There’s not many birds
that– coo-koo. – ( laughs )
– A hummingbird…
hummingbird, sure. I can’t imagine
how tiring it would be to be flapping your wings,
you know, 60 times a second, ’cause I, you know,
get on the couch and I get
hungry sometimes. – ( laughs )
– Well, they eat a lot. they eat half their
body weight each day.They need a lot of energy.Their metabolism
is just outrageous.
It’s the fastest metabolism
of any creature or any animal. And they’re smart.
They can remember which flower
they were at and which one had a lot of
nectar and which one didn’t,and they’ll return to
the better flowers.
And they’ll get
territorial about that.
They’ll take their bill
and use it as a little spear.
They’ll just stick ya. Gav:Yeah, we saw in one of
the clips there was a dive-bomb
going on,
and the other bird had
to hop out of the way
pretty quick.
Dan:So once it dive-bombed it,
I was just wondering why
it was so territorial?
‘Cause it seemed
there was loads of food.
Yeah, there is loads of food,
but it turns out there’s
sort of two ways
you can go about being
a hummingbird, right?
You can stay in one place
and protect your one
source of food.
Or you can fly
all over the place
and visit, like, one
or two thousand flowers maybe. And it turns out
it’s cheaper just to stay
in one place. – ( laughs )
– You can save ten or twenty
percent of their energy expenditure in a day
by protecting a place instead of flying around. It sounds like British
tourists on sun lounges. – ( laughs ) Yeah.
– I parked it. So even if they’re
flapping their wings you know, 60 times
a second, they’re lazy. ( laughs ) They can’t be bothered
to go to 2,000 flowers. Well, thanks very much
for those amazing facts. – That was great.
– That was great, yeah. – Thanks a lot for coming.
– Thank you. Okay, so we’ve done a comparison
between different bird wings, but we also filmed the eye lid
of a golden eagle, and I’d be interested
to see who blinks faster, the eagle or Daniel. We have a blinking
competition going on. – You ever been in one?
They’re brutal.
– I’m ready. This might be the easiest thing
I’ve ever had to do for us. I usually ask for a little bit
more of you, but this one, all I need
you to do is blink. Just stand there. Okay, when you’re ready
for me to blink. – You just did.
– Dan: Oh. ( laughs )
I got it. – That was it.
– All right, show’s over, guys. I feel like if I asked you
to blink, you would do a very
unnatural blink. – Dan: I’d be like–
– Gav: So I just got a blink. Okay, I’m just gonna cue it up
and then we’ll go and compare the speed
to our eagle. All right. Okay, we have them cued up right before the blink. Place your bets. Who’s faster? I’m the fastest blinker
in the west, so… – Yeah?
– Dan: Yeah. Okay, let’s compare,
are you ready? – Yes.
– Okay. Three, two, one, play. – Oh, he smashed me.
– Gav: Wow. Absolutely smashed me. Gav: And I feel like you barely
completed the blink. – Just finished.
– Your eyelids barely met. You like mostly blinked. Yeah, I already like
half blinked and then mostly did it.
That’s ridiculous. Ah, it’s just majestic
isn’t it? I mean, yeah, the way
my eyebrows are… just so bushy and nice. ( laughs )
What? Well, I’ve learned something.
Hopefully you learned
something, too. Feel free to subscribe

15 seconds I’d be so fat.

  1. I got 15k for my teeth going through my just below my lip…leaving a minor scar…how big is a 31 year scar when in prison for something you didn't do

  2. PPProve that the tiny one is an insect, has no feelings (perception) in that mechanical part (torso), moves it in "conditrion of being" and doesn't "develop" personal traits in relation to it (pretty much like lip-synk-ing) Also would PPProve that micro(scopic) world doesn't exist since automation "needs" a public to operate (sth like food chain/ :::SSSensational chain…)… so yeah, don't do comparative science because you guys, not being Sindbad, you have the right to imprison an eagle…(some slim libido, mmh./../..) …hope you know that there are consequences..

  3. I came here to see slow motion birds, but instead 2 unfunny guys with mandatory beards are trying to make me laugh.

    Кто прочитал ставьте ла'йк.под коментом'пусть они дум'ают что я что-т'о умно'е написал!'ну и видос посмотрите мой за одно.

  5. The hummingbird is so amazing. I could watch them all day long, and have! Put up a feeder and watch their cool magical flight:))

  6. Fun and knowledge both together…. I don't know why people are crazy about poo and too ….you doing great .. love u guys..

  7. One more interesting fact about the hummingbird, I learned this in a biomechanics class in college: there's no muscle in the world that can contract rapidly enough to beat a wing 60 times a second. The way the hummingbird does it is that the muscles only contract once every five or ten flaps and that puts enough energy in the movement of the wing so that all the following flaps occur because of elastic tendons that act like rubber bands and store that energy, like bouncing a weight tied to the end of a bungie cord. If memory serves the same sort of thing happens in insects whose wings beat insanely fast, like bees and flies.

  8. Вот я сижу чешу лобок и понимаю что колибри это удивительно!

  9. Hummingbirds are so dope. Love watching them on the feeders in my backyard. At my aunts place in the mountains, if you’re patient enough they will land on your finger. I have some pictures of them on my finger. Pretty sick.

  10. no one:
    humming birds: flapflapfalpflapflapfalp flapflapfalpflapflapfalpflapflapfalpflapflapfalpflapflapfalpflapflapfalp

  11. اكذب عليك لو قلت بحبك لكني أرغب فيك وبشدة والباقي اقولك عليه بعدين 😘

  12. Humming bird: 47and 1/2 flaps
    Eagle : Few flaps
    Humans: Not really need to flap just ride.on a aeroplane 🤓

  13. Whenever there is something to do with air, and you can include Schlieren videography, please do use it.

  14. лично мне поебать

    100К- 10РУБ
    1МЛН- 100РУБ
    1МЛРД- 100РУБ

  15. It looks like they counted "1 flap" as every time the wings changed direction. I'd argue "1 flap" is one complete motion from position A, to position B and back to position A again. Then again, the hummingbird does generate lift on both strokes so maybe it's a special case.

  16. The numbers I've always read about the speed of their flaps always have seemed outlandish to be but now I can see it with my own eyes. Amazing.

  17. The eagle blinking was so cool, it got me intrigue. Have Gav and Dan ever filmed a dog drinking water? I've always been curious how they get water, and how much, with their tongues. I've tried and I don't get a lot, but my dog's tongue kinda looks like a thick spoon, so…?

  18. I get the impression Dan doesn't really appreciate hummingbirds.
    I luv SLO-Mo stuff – but, I'm more loyal to hummies..🤷‍♂️

  19. Not sure if have the right kind of cams for it, but some underwater slomo footage of animals could be awesome, especially if some food coloring or light refraction was used to highlight the hydrodynamics of the penguin or puffin.

  20. Wait a second, isn't a "flap" defined as every time the wing tips touch in the front of the bird? Wouldn't it be 24 full flaps per second?
