GEORGE: Let's hope we don't see what the lions do at night.
(WILL LAUGHING)
Let's hope we see lions before they see us.
(WILL LAUGHING)
Hey, Rem. Can you cut the lights?
Cool.
(CRICKETS CHIRPING)
Well, this is... We got a pair of night vision goggles,
and if you look out there, and tell me what you see.
I need night vision goggles to get the night vision goggles from you.
(BOTH LAUGH)
Well, I can see they're wildebeest.
GEORGE: Well, that's a start.
Can you tell their shape? Like the shape of the... of the group?
WILL: I can't tell, really...
They're like layered up, so I can't really tell.
-GEORGE: Kind of stacked up? -WILL: Yeah.
GEORGE: I don't know. Let's see what... I've got a... another toy
I wanted to show you.
(BIRDS CHITTERING)
(WILDEBEEST GRUMBLES)
(FOLIAGE RUSTLING)
I wonder if a lion could see in this kind of darkness. I dunno.
WILL: Well, that's... We don't need to find out that. (CHUCKLES)
GEORGE: No, no, I just die... I'd... I'd die with the wildebeest.
-You can follow me? -WILL: I can't see.
-GEORGE: Yeah, I got you, we're good. -WILL: All right. Hold on.
WILL: My whole life, I've wanted to see wildebeest.
I just didn't think it would be in the dark with lions everywhere.
But George has a different way of looking at everything.
(CAMERA DRONE WHIRRING)
(DRAMATIC MUSIC PLAYING)
GEORGE: Well, we're looking at these guys, it's interesting, they're moving out.
WILL: Oh, wow, yeah.
GEORGE: But I don't think they can see anything at night.
So they're falling in like that, but they're not falling in based on sight?
GEORGE: That's right.
They're walking differently.
Almost kind of like a loose defensive formation.
They're coming together and working as a group.
-They're clearly following each other. -GEORGE: That's right.
WILL: But if they don't see well, and they're not making any noise,
how do they know where the others are?
Around thirty years ago, I picked up a National Geographic Magazine
and saw this.
That image, one and a half million wildebeests on the plains of Africa,
has stayed with me ever since.
The most dramatic migration on Earth.
And finally, I'm here to see it.
(YAWNS AUDIBLY)
GEORGE: Hey, Will. Come up and take a look.
WILL: All right.
(GROANING)
Whoa!
GEORGE: That's a lot of wildebeest, man.
(WILDEBEEST BLEATING)
WILL: Seeing them up close, finally. Man, they're kind of funny-looking.
(CHUCKLES)
GEORGE: Wildebeest are not the most elegant animal.
Or the most intelligent.
WILL: George is straight-up clowning wildebeest.
But, hey, if they don't get by on their looks or their brains,
how do they survive out here in the wild?
Well, that's what George wants me to see.
The front runners chow down on the grass ahead of the herd,
so they all have to keep constantly moving.
And so do we.
So, George, what got you to... to Africa?
I got kind of bored, I was a... kind of bored college student,
and I decided to get the hell out, and I wanted...
I went to Africa, I came hitchhiking here.
-I bought a one-way ticket to London... -Wow.
-...and I hitchhiked down to Congo. -Whoa.
And I found it was really fascinating and there was so much more to learn.
-WILL: Yeah. -And I still feel that way.
Once you get into dangerous things, you just keep on learning more and more.
WILL: Yeah. Exactly.
What kind of image are you hoping to capture?
Well, I'm trying to capture the key moment in the migration
when the, um... when the wildebeest cross the river.
How often do you capture exactly what you're looking for?
(BOTH LAUGH)
That's kind of a depressing question.
(LAUGHS)
GEORGE: I've been photographing wildlife for over forty years.
As a photographer, you try to capture these incisive moments in an animal,
where they reveal the true nature of their species.
And the greatest, the biggie of all, is the crossing of the wildebeest.
(BLEATS)
In your experience, Rem, how rare is it?
How easy will it be for you to catch a crossing?
You have a big chance of seeing a wildebeest, of course.
-WILL: Yeah. -But it's seeing crossing,
that's very rare.
But I think you can consider it a great failure
if you don't show me a... a crossing.
-Of course. -(LAUGHS)
You know, wildebeest don't care...
wildebeest don't care who you are, or how long you've been waiting.
-I know, right. (LAUGHS) -They don't really care.
Hey, you guys, do you know what? The wildebeest haven't seen
Men in Black, I guess. (CHUCKLES)
(WILDEBEEST BLEATING)
In fairness, they've got more pressing things to think about.
But somehow, between them, they manage to survive a 300-mile trek
past hungry lions, hyenas, and cheetahs.
What's their secret?
Perhaps the answer lies in a completely different creature
over 3,000 miles away from here.
(BIRDS CHIRPING)
(SOFT VOCAL MUSIC PLAYING)
(THUNDER RUMBLES)
(BEES BUZZING)
WILL: But what can the world's largest honeybee
tell us about wildebeest?
ALDO: Have you seen bees like this before?
CORY: I've never seen anything like this before.
Your problem's gonna be how to get in there and be able to then...
-sort yourself out to be able to shoot. -Not... Okay, yeah.
-So I'm not spinning in space. -Yeah.
(BEES BUZZING)
ALDO: Maybe we'll try and climb up from the bottom
and then, from there, try to get in position.
Well, I guess we should go try it.
(BEES BUZZING)
MALE VOICE:
(SPEAKING NEPALI)
(SUSPENSEFUL MUSIC PLAYING)
MALE VOICE 1:
CORY: There can be as many as 100,000 bees on a single hive.
And they can be pretty damn hostile.
If they decide to swarm when you're at the top of a rope,
there's literally nothing you can do.
(INDISTINCT SHOUTING)
(BEES BUZZING)
Aldo, I'm in position!
ALDO: (OVER RADIO) Can you get quite close? Over.
CORY: I can touch it.
I can touch the outer part with my hand and the inner part with my foot.
I'm gonna try to trigger 'em.
There's a sort of invisible barrier around a hive.
It's about 20 inches away.
Cross that line, and something astonishing happens.
(WHIMSICAL MUSIC PLAYING)
Wow. Incredible.
It's a kind of defense strategy.
If the bees spot a predator breaking through that perimeter,
they flip their bodies, starting this massive chain reaction.
It's like they're somehow all connected, and not just by touch,
but like they're thinking as a single unit.
(BEES BUZZING)
WILL: On its own, each bee doesn't amount to much.
But as a swarm, they can create something big enough
or confusing enough...
to deter almost any attacker.
(CAR ENGINE WHIRRING)
So the bees have their shimmer trick to throw off predators.
But the wildebeest don't have that.
I don't think.
So how do they defend themselves?
Rem, there's a lion over there. Can we stop for a minute?
Look out on the left.
WILL: Oh, yeah, I see her. I see her.
(WILDEBEEST BLEATING)
GEORGE: And...?
WILL: She's gone again. I lost her.
GEORGE: Let's try changing our perspective.
(CAMERA DRONE WHIRRING)
GEORGE: I've always loved getting up and looking at things in a new way.
When I was a kid, I was a real tree climber,
much to my mother's chagrin.
I loved climbing up to the tallest branches
to get a view over my back yard.
And now my back yard's become a lot bigger.
WILL: Any luck?
Can you see her?
Wow!
Like a flash mob.
If it were humans down there, that would be chaos.
I'd be tripping up and bangin' off this dude,
and runnin' into that guy over there.
But the herd didn't miss a beat. Just kept on keepin' on.
It looks difficult.
But it turns out, you just have to follow three simple rules.
Rules that apply to all sorts of animals that swarm.
Rule number one, don't get too far away from your neighbor.
Rule number two,
don't get too close to your neighbor either.
Rule number three, if your neighbor turns, you turn.
And that's enough to turn thousands of individuals
into something beautiful and complex.
(WINGS FLAPPING)
Starlings can fly at 40 miles an hour.
So to keep together in formation, they need the reactions of racing drivers.
Especially as the other "cars" aren't just in front or behind,
they're above and below.
It's hard to get how special that is, until you see it mapped out.
A hundred thousand birds racing around a constantly changing track
without a single crash.
That's the way the wildebeest roll too, with simple rules and not overthinking it.
They're not as fast or as pretty, but as they search for fresh grass,
the wildebeest are just as coordinated.
Things get more complicated when they reach the Mara River.
Keeping an eye on the guy next to you isn't much use,
when you're facing strong currents... and giant crocs.
It's the single most dangerous part of the whole 300-mile round trip.
(TRUCK ENGINE WHIRRING)
Wait, we can get out here?
GEORGE: It's safe. Yeah, get out.
WILL: I'm gonna let you get out first. (LAUGHS)
GEORGE: "That looks good, you go first?"
(ALL CHUCKLE)
WILL: What are we looking at?
Uh, basically, this is the main barrier that the animals have to go over
to get up to the big grasslands of the Mara,
where the really good vegetation is for them at this time of year.
So, what... what are all of these marks?
REMTULLA: Uh, those are the crossing points, so we mark it.
Like, it's along the river,
so whenever they cross, we just put the mark,
so we know like, crossing number two, number three, number four.
GEORGE: They seem to have a few favorite places.
But if they cross at regular spots, why is it so hard to catch a crossing?
There's no way to know which one they're going to choose.
Ah, okay.
Conglomeration of thousands of animals,
and they all might have crossed at a different place the year before,
so they've gotta have like a group decision,
-like a swarm decision, -WILL: Wow.
about which way to go.
We can either hold and wait in one spot, or we can get fidgety and patrol.
If there was a crossing happening, we can go there,
but by the time we get there, it might be over,
so it's like, do you...
It's hard to know whether you chase after crossings
or do you wait for a crossing to come to you.
Got it.
So, how long will it take for me to get comfortable
just letting a fly be on my face without having to swat it?
'Cause you got two flies on your face and you're just relaxed.
(ALL LAUGH)
-I'm like, man. -I just get tired of swatting at them.
Oh, yeah? (LAUGHS)
-Bush... Really bush man. Yeah... -Oh, man...
All right, so are we waiting or are we chasing?
My instinct is to find a really good place.
We got a lot of animals over there. And if we're in wait, they'll come to us.
-WILL: All right. -Yeah.
(TRUCK ENGINE REVVING)
So we sort of look where they're moving to, right?
Yeah, they're coming to the river. And see, the herd is down here.
WILL: Yeah.
-They're moving faster, yeah. -GEORGE: Trying to run there...
GEORGE: Are these guys about to cross?
I can't believe how lucky we're about to get.
WILL: Never underestimate the power of beginner's luck.
I mean, George has been trying to get this shot for years,
and I'm here two minutes and it's all happening.
I'm just saying.
(TRUCK ENGINE REVVING)
Go, George. This is your big moment.
(WATER SPLASHING)
(BLEATS)
He's going on his own.
(BLEATS)
Oh, I can't watch this.
-(BLEATS) -(MUSIC ENDS SHARPLY)
Oh, man.
(WILDEBEEST BLEATING)
Why did they let him go alone?
Looks like there's a fourth swarm rule.
Don't go where there's crocs.
(THUNDER RUMBLING)
If I saw one of my boys get wacked by a crocodile,
I'd have second thoughts about crossing that river too.
Looks like the momentum now is moving away from this point.
Where it was moving toward this point before,
now it feels like it's kind of gently drifting away.
(THUNDER RUMBLING)
Clearly, one brave dude jumping into the water
is not enough to make them all start crossing.
So, what will it take?
To best explain that, we need to go underwater.
(WATER LAPPING)
JILL: They are truly amazing.
The first time I ever saw them,
certainly something that you'll never forget.
(WATER ECHOES)
(TENSE MUSIC PLAYING)
(INDISTINCT RADIO CHATTER)
WILL: Flashlight fish are weird.
They make their cheeks light up like, "I'm here, follow me!"
But just like that poor wildebeest,
one fish signaling isn't enough to make the others follow.
Neither is two or three.
But if enough of them flash at the same time,
in the same direction...
(UPBEAT MUSIC PLAYING)
...they all go.
It's not about one animal taking the lead. It's about enough of them doing it.
Then the swarm behavior kicks in strong.
So this is a numbers game.
The place where the wildebeest are most likely to cross
is the place where the biggest numbers are gathering.
(PLANE ENGINE WHIRRING)
But how do you find that?
Well, with a plane with the doors off, and a crazy co-pilot.
(DRAMATIC MUSIC PLAYING)
Here we go.
WILL: Oh, wow.
Come forward, you can see it better.
WILL: That's a huge line.
That's definitely the most we've ever seen.
That's crazy. It does look like ants, like how you see ants move.
-Yeah, like army ants. -Army ants, yeah.
Exactly.
There's a few thousand there at least. A convoy.
WILL: That one's even bigger.
You can definitely tell where this bunch is heading.
Straight to the river.
GEORGE: We gotta get there before they start crossing.
WILL: Roger that. Let's get down there.
(PLANE WHIRRING LOUDLY)
Let the games begin.
(TRUCK ENGINE WHIRRING)
Look at that line, those lines.
WILL: Have we found our crossing point, Rem?
REMTULLA: Yeah.
So, I think we better hold here.
'Cause if we drive close, may scare them, they may run away from the river.
So our presence would potentially keep them from crossing?
True, yeah. So, we'd better continue to wait.
WILL: So, now we just wait for someone to call "action"?
Welcome to wildlife photography. It's a lot of waiting.
(WILL CHUCKLES)
Eh, it's not different than acting either.
-(CHUCKLES) -You just kinda sit around and wait.
(WILL HUMMING)
-(BIRDS CHIRPING) -(WILL HUMMING)
GEORGE AND WILL: (SINGING) A-wimoweh, a-wimoweh
A-wimoweh, a-wimoweh
In the jungle, the mighty jungle
The lion sleeps tonight
In the jungle, the mighty jungle
The lion sleeps tonight
Woo-oo-oo-ooo Ee-e-e-oh-mum-a-weh
I'm out of breath.
("THE LION SLEEPS TONIGHT" PLAYING)
Weeheeheehee dee heeheeheehee weeoh aweem away
Near the village, the quiet village

Weeheeheehee dee heeheeheehee
Weeoh aweem away...
Weeheeheehee
I'm a real explorer if I have a slouch hat?
-REMTULLA: Yeah, exactly. -All right, so that... so... so...
so it's like... it's like, that's the vibe?
Weeheeheehee dee heeheeheehee
Weeoh aweem away
(EXHALES)
-(WILDEBEEST GRUMBLING) -(CRICKETS CHIRPING)
GEORGE: It looks good. You go first.
WILL: I'm not gonna go first. You go first.
-GEORGE: No, you go first. -REMTULLA: No, you go, you go.
-WILL: I'm right behind you.
Just go ahead. I mean, you're already standing there, just go ahead.
Yeah, I got your back, man.
(ALL LAUGH)
WILL: The single brain is saying, "I don't want to get eaten."
But the swarm mind is saying, "There's grass over there. Let's go."
It's a pressure cooker.
Maybe what they really need is one last push.
(DRAMATIC MUSIC PLAYING)
There are tiny dots of slime mold almost everywhere.
Most of the time, slime mold just sits around,
eating bacteria and making more slime mold.
But when these single-celled organisms run out of food,
something weird happens.
Waves of restless energy ripple through the swarm.
They join themselves together into a new creature.
Many cells become one body.
And then when the pressure finally gets too much, they move.
There's sacrifice involved.
The long, thin stems are created by cells dying.
But they give the others a chance to survive
by being carried away to pastures new when something brushes against them.
Individually, these guys are literally brainless,
but together, they're smart.
And wildebeest? They're a bit like slime mold.
No offense.
Loads of individuals somehow having to make a joint decision.
Thousands of brains slowly crunching the data.
(CROCODILE HISSING)
"Danger in front...
"food running out behind."
Waves of nervous energy building...
that finally pushes them to the edge.
-And an answer. -(MUSIC GETS QUIETER)
(MUSIC CRESCENDOS)
REMTULLA: They're going. Going.
-WILL: They're gone. They're gone. -GEORGE: They're going.
Look at that.
Oh, man.
-All right, you got the... -REMTULLA: They're crossing.
-Get the bino... -WILL: Thank you, thank you.
(STAMPEDE RUNNING)
(INTENSE DRAMATIC MUSIC)
That's spectacular.
(WILL LAUGHS)
That looks crazy.
-Wow. (LAUGHS) -GEORGE: Wow.
(WILDEBEESTS BLEAT)
WILL: I've had more than half my life to get ready for this.
But nothing prepares you for the dust,
the noise, the sheer scale of it.
Wow!
Hey, that... Once you commit...
GEORGE: No turning back.
All right, 30 years. That was on my bucket list for like 30 years.
We just got it, the migration of the wildebeest,
the crossing of the river.
We have done what we have come to done.
Thousands and thousands of individual organisms
surviving by joining together.
The swarm drives them and protects them.
Not everyone can make it.
But most of them do.
Look at them go. It's like they're tied together.
You can, like... You can feel the connection.
So it looks like, even from...
What could be a quarter mile away, that they know.
Like these all the way back here, can sense what's happening up here.
For almost 30 years, I've had an image in my mind.
The plains of Africa dense with millions of wildebeest.
But in the end, I saw something I wasn't expecting.
It's not millions of animals at all.
It's just one.
(DRAMATIC MUSIC CONTINUES)
Like George said, shift your perspective,
switch your lens,
and you'll see the swarm everywhere.
Makes you wonder, do they even know they're in a swarm?
Come to think of it, do we?
Damn. Now, that's a question.
(UPBEAT MUSIC PLAYING)
Next, I'm on the trail of a deadly predator.
MALE VOICE: Shark!
-Whoa, there he is. -Mm-hmm, you got one.
WILL: Aw, yeah.
Following my nose to solve a desert island mystery.
Whoa, that is gorgeous.
And discover that smell is not what it seems.
(THEME MUSIC PLAYING)
