Today, we’re in Shawnee,Oklahoma,
这里有大雕 老鹰 还有蜂鸟
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?
Look at that. Wow.
And action, hummingbirds
Go on, son.
Whoa, look at that.
Oh, he is just not happy about it.
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.
because you can’t tell anmials to do something as expected 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 we turn around; pretend we’re not looking.
Look at his feathers
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 how 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 them.
Ok, 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.
对啊 必须得有 慢动作镜头嘛
Yeah, I mean, you do. It’s slow mo footage.
All right, ready.
One. That’s two.
Yeah, now it’s on three.
This is three right now.
That was three.
This is three, yeah.
That was three.
Now this is four.
Four. We might have to speed this up.
行 一秒时间到 48次
All right, that’s one second.
Uh, it’s sort of 47 and a half
because it’s sort of half way.
Like the hawk bends its wings halfway
That’s right. You’re not getting all the credit.
Only 47 and a half
In one real time second, that is really fast.
It doesn’t seem amazing when you’re watching it back on slow-mo.
I mean, are you saying that our slow-mo made him less impressive?
How many flaps could you do in one second?
An entire flap?
Ok, 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.
Yeah, that’s two different worlds right there.
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.
– 好啊- 嗨 彼得 感谢你的到来
All right.Hey, Peter, thanks for coming on. Hey,
Thanks for having me. It’s great to be here.
So we’re with the hummingbird expert, so,
I don’t know much about birds.
I’m hoping you could enlighten us.
– 很乐意- 好啊
– 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 usuallythey 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 flap
and the back swing, is that right?
Peter: They’re the only birds to do that.
Dan: The only birds to do it?
Yeah, and they do that
because they’re able to flip their hand over.
It’s basically their wristgoing back and forth.
So it’s able to get lift in both directions which is —
it still has the same stroke,
forward and backwardsthat another bird does,
but it’s flipping and able to get liftin both directions.
They’re the only birdI’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.
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.
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 metabolismof 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 getterritorial about that.
They’ll take their billand 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 seemedthere was loads of food. Peter:
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.
– [大笑]- 待在一处时所用的能量
– [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.
– [大笑] 的确- 这座我占了
– ( 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 botheredto go to 2,000 flowers. Well,
thanks very muchfor those amazing facts.
– 太棒啦- 真的太棒啦
– That was great.- That was great, yeah.
– 非常感谢您的到来- 谢谢 好了
– Thanks a lot for coming.- Thank you.
Okay, so we’ve done a comparisonbetween different bird wings,
but we also filmed the eye lidof a golden eagle,
and I’d be interestedto see who blinks faster,
the eagle or Daniel.
We have a blinkingcompetition going on.
– 你参加过吗？这种比赛很残暴的- 准备好了
– 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.
– 你刚刚眨了- 哦
– You just did.- Dan: Oh.
( laughs )I got it.
– 拍完了- 表演结束了 朋友们
– 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.
– 我就……- 我拍到了 好了
– Dan: I’d be like— Gav: So I just got a blink. Okay,
I’m just gon na 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.
I’m the fastest blinker in the west, so…
– 确定？- 确定 好了 来比较一下 准备好了吗？
– Yeah?- Dan: Yeah. Okay, let’s compare, are you ready?
– 好了- 行 三 二 一 开始
– Yes.- Okay. Three, two, one, play.
– 啊 他秒杀我了- 哇
– Oh, he smashed me.- Gav: Wow.
Absolutely smashed me. Gav:
And I feel like you barely completed the blink.
– 眨完了- 你的眼皮几乎没碰到一起
– Just finished.- Your eyelids barely met.
You like mostly blinked. Yeah,
I already like half blinked and then mostly did it.
it’s just majestic, isn’t it?
I mean, yeah, the way my eyebrows are just so bushy and nice.
What? Well, I’ve learned something. Hopefully, you learned something, too.

– If I had to eat every 15 seconds, I’d be so fat.- ( laughs )
