Episode 2 Animals with Cameras

GROWLS

As a wildlife cameraman, I have travelled the world,

trying to capture life's most intimate and dramatic moments.

But wouldn't it be incredible if we could see the world

from an animal's point of view?

Well, in this series, that is exactly what we're going to do,

with the help of the animals themselves.

They're going to be the ones that are doing the filming.

They're going to take us to places that a cameraman like me

simply cannot go,

and reveal a side of their lives like we have never seen before.

Working with scientists,

we're designing cameras small enough to take us into their hidden world

for the first time.

-We're heading in.

-Wow. Barging past some pups.

Our camera crew is one of the most diverse teams to ever film

a wildlife series.

From 30-centimetre tall meerkats...

..to 60mph cheetahs.

From free diving fur seals...

..to nest-building chimps.

Our unconventional film crew are revealing surprising behaviour

and giving us new insights into how they live their lives.

-Wow.

-That's really cool.

Instantly, you get a real chimp point of view.

This is their world, their footage.

-Oh, yeah, look.

-Wow!

Their story.

And we're going to see it through their eyes.

She's definitely got her game face on.

In this programme, our cameras reveal the hidden lives

of three very different families.

In Australia's shark-infested waters,

we discover how fur seals escape from the deadly jaws

of one of the ocean's top predators.

Oh, wow. Goodness me.

In South Africa, we see the conflict between baboons and local farmers.

With tensions mounting, could our cameras help find a solution?

The cameras are basically my last hope.

But my adventure begins in the wilds of Namibia.

This is a stronghold for Africa's most endangered big cat,

the cheetah.

Famously, cheetahs are spectacular sprint predators,

chasing down their prey over the open savannah.

That's how I've seen them in the past.

In the open grassland, it's easy to watch these incredible athletes.

But, here in Namibia, they live in bushland,

where they're much harder to see.

We're hoping our cameras can help us

follow the lives of three very special young cheetahs.

Conservationist Marlice Van Vuuren adopted this trio

when they were orphaned at just one day old.

They still rely on Marlice for food,

but she wants to find out if they can catch their own prey.

Come.

Come!

Come.

She's hoping our cameras could help her track their progress

as they learn to hunt in this dense scrubland.

Who are your friends?

-This is Odyssey.

-You're beautiful.

-Male?

-Yeah, he's a boy.

-OK.

-He's a male.

-What about the other two?

They're two females, Shiloh and Wonder.

Odyssey and his sisters are now 18 months old.

By now, most wild cheetahs would be making their own kills.

But these orphans have had no-one to teach them.

Can they work out how to hunt for themselves?

So, going to show you what we've come up with.

-This is the camera.

-Oh, OK.

-Feel the... Feel the weight.

-Yeah.

And this goes on the head?

On the head. What do you think?

I would love to see the footage out of this.

And it's nice that it's nice and elastic,

and it's not going to restrict them at all,

so I think it will work.

The cameras look good to us,

but the youngsters will decide if they're happy to wear them.

-Who is this? Is this Odyssey?

-This is Odyssey.

-OK.

The one that sits down.

Hey, Odyssey.

Odyssey's sister, Wonder, is first up for a fitting.

Camera's running.

I keep one part of my shirt clean, so I can clean the lenses.

OK. That's perfect.

-Look at you.

-Look at you!

Well, she's not upset,

otherwise she would immediately start clawing and stop purring.

She's happy.

I'm their mum. To see what they actually do when I'm not there,

it would make me very proud to know

that they're actually doing very good.

Huh? Hello.

You want one? He's asking, "Where's mine?"

It's all the latest thing amongst cheetahs in this part of the world.

Don't worry, no stress.

There we go. You are... There we go.

-Quite a couple.

-Yeah. With new bling.

-You happy with that?

They've got Bushveld bling.

With two of the three cats wearing cameras,

we watch them head into the bush.

They're soon out of our sight,

but the cameras are filming their every move.

I don't know about you, but I'm very excited we're seeing this.

OK, here we go.

Wow.

That's quite incredible.

That's what it looks like to be a cheetah.

-Oh, he's rolling around.

-That's fantastic.

You can see, they're just kind of chilling out,

enjoying being together.

This is an intimate insight into the cheetahs' lives.

Oh...

Watch the camera.

Head shake.

While Odyssey takes a drink,

Wonder finds a good scratching post.

And it's not long before our playful young cheetahs

decide to stretch their legs.

And we're running with the fastest mammal on Earth.

-Oh, wow.

-Yes, it's beautiful. Look at the tail.

Wow. That is stunning.

Absolutely incredible.

Oh, look at that.

It's an amazing insight into the youngsters' lives.

But what we really want to know

is whether they can hunt for themselves.

Hopefully, the cameras will give us the answer.

I'll also try to film them for as long as I can.

Trying to spot the three cheetahs.

They've gone into this very thick bush,

and...

I don't know where they are.

None of them. Any of them.

They're all gone.

It's only when Odyssey emerges from the dense cover

that I finally find him.

Or, really, it's more a case of him finding me.

Hey, beautiful.

No, no, no, no. OK, I think you're going to jump up onto the car.

To get a better view.

OK, that's fine.

With this gain in height,

Odyssey can see so much more than he can see

when he's down on the ground.

So this isn't about a cheetah coming to say hello to us,

it's about just kind of having a better field of view.

Maybe saying hello as well.

That's not what you're supposed to be doing.

You going to go hunting?

Where's your sisters?

There's no room in the back, if that's what you're thinking.

Odyssey's not showing much sign of independence just yet.

But he does finally head off to rejoin his sisters.

They've spotted a herd of gemsbok in a clearing.

For young cheetahs, these are a very dangerous target.

Three cats altogether.

They look like a force to be reckoned with.

I don't quite know how this is going to play out.

I have seen cheetahs hunt before, but out in the open plains,

and I'm not sure how it's going to change their behaviour,

somewhere as thick as this. It's very, very scrubby and bushy.

OK, cheetah there, moving in.

Right.

OK, one's running.

Second one running.

Towards the game.

They don't yet know that the cheetahs are gaining on them.

They're actually just...

OK, full-on run from the front cheetah, a full-on run.

No, they're just scattering the herd.

The gemsbok panic.

The cheetahs are after an easy target.

OK. Oh!

Confusion, confusion.

It's very hard trying to keep track of three cheetahs.

Wonder's camera captures what I can't see.

She's chasing one animal away from the group.

In amongst the bushes, Wonder's losing speed.

Her sister Shiloh charges in on the left,

but the gemsbok is now so far ahead, it's safe.

The thick vegetation has scuppered our cheetahs' chances.

Wonder skulks back to the clearing,

where the tables have turned.

Oh, just got charged by a big, big gemsbok there.

They're now at risk of being skewered by this large male.

The prey knows that the predator is around -

the cheetah have lost their advantage.

Ah!

Now they're just getting chased away,

they're being humiliated.

Taking on such a large prey was a real rookie mistake.

But will they learn from the experience?

Over the next few days, the cameras keep rolling.

The youngsters need to turn this scrubby terrain to their advantage.

And soon, we see encouraging signs.

The three cheetahs are following animal trails in the undergrowth.

Shiloh appears to sniff the ground, to work out what prey is around.

See, this is impossible.

-There's absolutely no way we could see this any other way.

-Uh-huh.

They're also using the thick bush as cover.

The closer they can get to the prey,

the more likely they are to make a kill.

-They're trying to get eyes on.

-Hm.

Odyssey creeps forward.

He spots the target

and freezes.

So his sister's on his left, one of them.

That's a clear sign that they're working together,

because he sees the prey, stops, checks his sister's there.

-And then he's looking back to the prey.

-Yeah.

And there he goes.

Oh, my God!

Oh! It's a youngster.

My God!

One of his sisters is in front.

It's a baby. It's a baby eland.

Yeah.

Look at that. Oh, my gosh.

His sister, Shiloh, tries to trip the calf.

Oh, so close.

Oh, my goodness me.

What on Earth?

Odyssey is forced to swerve to avoid a thorn bush.

Could you see the difficulties of negotiating those bushes?

And now the mum's trying to keep them away.

-There she goes.

-My heart is in my mouth.

That is quite something.

A cheetah can only sprint at top speed for ten seconds,

so the eland and her calf manage to escape.

I'm completely blown away by these images.

-It's brilliant to follow them.

-Hm.

What are they actually doing in the Veld?

-Yeah.

-You know, and I'm proud as the mum of them.

You know, they're actually working in a team

and they... They have huge challenges, and they take it.

They're not scared. So this is amazing, this is really a good idea.

But Marlice has yet to see a successful hunt.

We leave our cameras with her,

to keep watch on the youngsters' progress.

For our next mission, I'm travelling to the south coast of Australia,

to the remote and rugged Kanowna Island.

Few animals have what it takes to survive out here,

but there's one hardy sea mammal that does.

The island itself is more of a rocky outcrop.

It's uninhabited but for the thousands of fur seals

that call it home.

On the island, the fur seals are safe.

But the surrounding seas

are deadly...

Teeming with the ocean's most feared predator,

the great white shark.

I'm here to help scientists to discover

how fur seals avoid the sharks

and thrive in this unforgiving wilderness.

We're hoping our cameras will help solve the puzzle.

There it is.

Home, sweet home.

Leading the research team is Professor John Arnold.

-Hello.

-Gordon.

-Nice to meet you.

-What an amazing, amazing place.

-Thank you.

-Good to meet you.

For the next week, this windswept spot will be my home.

Oh, perfect. Everything a man needs.

John's team have been studying the seals for 20 years.

But their lives out at sea are still shrouded in mystery.

So what are the big questions you want to be answered

by the seals taking cameras with them?

They spend up to 80% of their lives at sea.

Every time their mothers leave the colony,

they have to run the gauntlet of any sharks that are out there.

What are they doing?

Just seeing them on shore gives us a very small view of their life.

The big Holy Grail for us, is what are they seeing?

What are they hunting?

How successful they are at catching prey...

It's a hard life for these seals.

There are around 15,000 fur seals on Kanowna Island...

..so it's no surprise that the island's a magnet for great whites.

These giant sharks specialise in hunting marine mammals like seals.

Our first challenge will be to test our cameras.

John's been fitting seals with trackers for years.

He operates with military precision.

His tactic is to keep low...

I'm going to sneak in, see what I can find.

Okey-dokey. ..keep quiet...

and bring a very large net.

OK, we've got her.

Let me know if there's anything I can do.

Our mother seal gets a light anaesthetic to help keep her calm.

-Wow.

-86.0, plus board, so she's 80 kilos.

At such a healthy size,

John's happy that she won't be hampered by a small camera.

-OK.

-Well done.

Go back.

While our mum goes on her first filming trip...

..I want to see what the seals get up to close to shore.

The theory is that this spot is too shallow for sharks.

It's the seal equivalent of a paddling pool,

a safe and sheltered spot where pups can learn to swim.

That is absolutely beautiful.

It is probably one of the nicest things I've ever seen underwater.

This cove is the only place

I can observe these seals beneath the waves.

But we want to understand their lives

away from the sheltered shallows.

And that's what the deployment of these cameras is all about.

Our camera testing seal has also been taking a dip.

Time to see what the footage reveals.

Heading down to sea.

See the way her shoulder blades are working.

And she's about to jump into the water.

There she goes. Into the...

Wow. Oh, wow!

Look at that!

As soon as she dives, the camera captures unexpected behaviour.

Oh, look at that. Look at that.

She's rubbing against the rocks.

Oh, yeah.

On that green stuff.

-They are rubbing...

-Wow, yeah, you can see it very clearly there.

Yeah.

And now she's rubbing the side of her face, her neck.

The other animals around her are doing the same thing.

-They're all doing it.

-Yeah.

-And you've never seen this before?

-No, I wouldn't have known.

I mean, you see them offshore at the surface, playing.

This is brand-new stuff. I've never seen this before.

Wow!

John thinks the seals could be using the seaweed to clean their fur...

..brushing up against it to remove parasites.

Already, we've captured brand-new behaviour.

We deploy more cameras.

Hopefully, these seals will head further out to sea.

We know from John's previous research that some seals will travel

as far as Tasmania...

..a 200-mile round trip.

But they face the greatest danger

from sharks within the first few miles of their journey.

There she goes.

Will our cameras finally reveal the seals' survival strategy?

You see seals coming ashore with injuries from sharks.

-They're the lucky ones that got away.

-Mm-hmm.

As soon as our seal enters the danger zone,

she heads straight down to the bottom.

It's a deliberate tactic.

Great whites prefer to ambush prey from below.

She's trying to slip under the shark's radar.

She can hold her breath for eight minutes...

..but then she must come up for air,

and this is when she's most vulnerable.

Now, she starts to swim in a completely different way.

All the time when she's coming towards the surface,

she's looking around. A 360 view.

In these dangerous surface waters,

she's doing everything she can to avoid a surprise attack.

Rotating her head gives her an all-round view.

Just constantly barrelling and it's just twisting and turning,

it's incredible.

-You wouldn't know that unless you had a camera on an animal.

-Yeah.

As soon as she can, she returns to the safety of the sea bed.

This is the first time John has ever seen how seal mums

give sharks the slip.

Further out, she switches into hunting mode.

Skimming over the sea floor has another benefit.

She's onto something.

It's a cuttlefish.

Wow!

Look at that!

-That's a big one.

-Like a big plate of ink.

The cuttlefish squirts ink to try and confuse the seal...

Wow.

..but it's too late.

I don't know if we've seen cuttlefish in their diet before.

Really?

18 metres down, her super senses soon detect something else.

Oh, what's she chasing here?

Oh...

-It's big.

-Oh, yeah.

It's a big octopus.

See it, it's the tentacles.

-Yeah.

-I didn't even see her grab that.

A struggling octopus is hard to eat.

Our seal risks heading to the surface.

Up here, she kills her prey and bashes it into bite-sized chunks.

Wow.

At the same time she's doing that,

-she's having to keep an eye out for sharks.

-Yeah.

The cameras have revealed how mothers specialise in hunting

on the sea floor.

But when this seal comes up for air,

something else catches her attention.

Is that dolphins?

-Yeah.

-Oh, wow. Wow, wow, wow!

Goodness me!

She's come across a bunch of dolphins feeding in the bay pool.

Oh, you can see her snatching them there.

Wow, that's incredible.

So, the presence of those dolphins is going to help her.

Well, I think she's just getting a free meal here.

The dolphins are rounding up the fish,

and the seal dives in for an easy meal.

-The...

-Oh, there's another one.

Wow, that's incredible!

Without the onboard cameras,

John would have no idea these seals take advantage of dolphins.

But once the dolphins leave, the fish spread out.

A lone seal can't keep them bunched together.

We see here that she's working really hard

and there's a huge school

of fish there, but she's getting very few of them.

With a belly full of food, she heads back to the sea floor.

These cameras have given us a remarkable insight into the lives

of these seals far out at sea.

For John, these insights have transformed his research.

You've learned more from, say, a two-hour video

of the animals underwater

than years and years of dive recorders and GPS

data logger tracking, because now you are seeing how they are behaving

underwater in response to what they're seeing.

Therefore, the cameras give us a brand-new view of their life.

Now we're facing a very different challenge.

On the other side of the world, there's trouble.

War is raging in the South African bush...

..between the local farmers and Chacma baboons.

The baboons' natural habitat is shrinking,

forcing them into farmland,

where they damage and eat the farmers' crops.

It's a battle that's threatening farmers' livelihoods.

Raino just harvested his butternut squash,

but half his crop was unsellable.

All of these butternuts, basically, in the field is all damaged

with bite marks, scratching marks.

That's the way they carry on, take a bite from each one.

Some farmers are already shooting baboons,

so a solution can't come soon enough.

Could cameras on the baboons reveal how to keep them off these crops?

Scientist Leah Findlay has spent the last five years

searching for answers.

So far, nothing has worked.

Baboons are very smart, they're very dexterous, agile.

It's basically like having a pack of ninjas on your farm.

Yeah, it's a pretty tricky problem to solve.

We try everything to stop the baboons.

In the beginning, we'd put branches, thorn trees around it.

It never stopped them.

We've tried rubber snakes, alarm systems.

We've made proper scarecrows that move like this.

Takes you about a week or so and then they're getting used to it.

We've tried electric fences, guards.

If the guards are walking on this side,

they will be on the other side of the field.

Then if she can run to that side,

then they will cross all the way backwards,

coming to this side again.

They are very clever.

These clever monkeys are not in the crop fields every day.

For the last week, the baboons haven't been raiding,

even though there are thousands of butternuts in the field.

If Leah can learn what is keeping them away now,

perhaps she can use it to keep them out permanently.

At this stage, I think the cameras are basically my last hope,

because I can't carry on like this.

Now, we just need to get our custom-built camera

onto a baboon.

I'm stuck!

Leah sets the trap, baited with the baboons' beloved butternut.

When something pushes down on the table,

it will pull the latch out and the door will slide shut.

As night falls, we have our first baboon.

A female. The vet anaesthetises her and fits the camera.

Over the coming days, Leah catches and puts cameras on more baboons.

There we go!

As the new day dawns,

we get our first glimpse into the lives of these secretive animals.

They slept in the trees for safety.

Now they're sunbathing to warm up.

That's beautiful footage here.

She's having a good look at it, isn't she?

So, this is basically our eyes now.

Whatever we see now, it's like through their eyes.

Yeah.

Considering this has only been on overnight,

-she's not bothered by it, is she?

-Nothing at all, not at all.

This one is grooming her.

Grooming is the way they socialise,

-so I think she might be a more dominant female.

-Hm.

It's wonderful to finally see the baboons' world.

But will this teach Leah and Raino how to keep them off the crops?

-Fence.

-Not even jumping over it, just going through it.

Yeah, just straight through, she pulled it down and she went through.

-It's like it's not even there.

-These fences, to be honest,

I don't think are going to stop them at all.

My opinion!

Does anything put the baboons off?

One of our cameras gives us a clue.

-And now they're running.

-Yeah.

-Because nice open area...

-Yeah.

Which suggests that they don't like being in it.

That's definitely something that we can think about

in terms of the crops.

Leah thinks an empty space around the crops

would be a better barrier than a fence.

And soon, we get more inside information.

The baboons are digging for water.

It's dry season, so the rivers have dried up.

But there is an easier way to get a drink.

Why bother digging when there's a water trough?

Has the camera gone under water?

Yeah.

Is it waterproof?!

Has to be.

It gives Leah another idea.

I'm just thinking about, you know,

keeping water points away from the crops,

because maybe having our water close to the crops is, you know,

drawing them in.

And finally, we learn why the baboons

aren't raiding at the moment.

This is the first ever glimpse

of what these baboons are eating in the wild.

And it goes like this,

it's basically every time they put a fruit in their mouth.

Yeah, yeah.

-At first...

-Just shovelling it in, yeah.

And it feels like she's going to feed you.

Yeah!

Same kind of fruit, that kind of roundish fruit tree.

Yeah, yeah.

This fruit could be the key.

It's from an alala palm.

They take up to four years to ripen and fall to the ground.

And when they do, there are thousands of them.

It's a feast.

The baboons are choosing this wild fruit over the butternuts.

When there's enough feeding and stuff,

they prefer to use their natural food.

-When there's plenty out there, they don't come in.

-Yeah.

You could plant more of these trees that have their natural food

that maybe they prefer. You know, that might be an option.

The peak time for crop raiding is the dry season,

when there is little other food around.

If Raino could plant bushes and trees that fruit in the dry season,

it might get the baboons through this hunger gap

and keep them off his fields.

Our cameras reveal a wide range

of the baboons' favourite fruit and berries,

showing Raino exactly what to plant.

I think we've definitely learned some new things.

We've learned a lot, yeah.

Does this make you feel any differently about the baboons?

Having a baboon's-eye view?

-Feeling more sorry for them, actually.

-Oh, really?

-Yeah.

-Why's that?

-It's their natural environment,

so there has to be space for everybody.

Leah has gained new insights into the feeding habits of the baboons.

These will be crucial to her effort to solve this tricky conflict,

finding a peaceful way for farmers

and baboons to coexist.

Back in Namibia, 700 miles away,

we've been putting our cameras on three orphaned cheetahs.

-OK.

-Fantastic, there we go.

Their surrogate mum, Marlice,

wants to know if they can hunt for themselves in the bush.

We've seen some encouraging signs...

Oh, she's seen something.

They're all up on their feet looking off in that direction.

I can't see what they can see.

..but until now, the cameras have captured near misses.

No successful hunts.

Several months on, Marlice is still using her cameras

to see how their hunting is coming on.

Odyssey flushes a warthog.

A warthog is one of the animals that they are most scared of.

The tusks on these powerful pigs can kill.

Just in time, he realises it's a mistake to follow a warthog

into the bush.

-SHE CHUCKLES

-He did give up.

A bat-eared fox...

It's just amazing that...

I mean, I didn't even know that they go for bat-eared foxes,

if it wasn't for the camera.

Shiloh and Wonder move in from each side...

..and the cameras capture their deadly strike.

With the cameras and with technology like this,

it just proves that actually without a mum,

without an adult showing them how to do it, and with opportunities,

they can actually learn.

By working together, they're becoming a formidable hunting trio.

And their choice of prey is getting better.

Springbok are one of the fastest of all African animals.

But up against cheetahs, this one has little chance of escape.

Success at last.

The right prey and the perfect technique.

I can see that they are ready.

They've learned a lot,

they are ready and they're working in coalition.

It's two females and a male together and making their hunt successful.

It helps me to kind of cut the umbilical cord and know

that they actually, really, they can go.

Yeah, it's really impressive to see and I'm so proud of them.

Our cameras have given us an insight

that otherwise would be impossible to see.

And it's the cheetahs themselves

that have given us their view of their world.

They have taken us with them deep into the African bush.

The cameras have shown Marlice that her three young cubs

can fend for themselves.

And our new insights into the lives of cheetahs

could help us to better protect these incredible big cats.

In this episode,

two very different African animals

presented us with two very different problems.

How to fit a camera onto the superfast cheetah...

..and the super-shy baboon.

It was up to mini camera expert Chris Watts to find the solutions.

When I first think about making a camera system for an animal,

a lot of it is kind of really studying how they move.

And with the cheetah, the first thing you notice

is that the head is so stable when they're moving and running,

the head is just completely locked.

And we all thought, how amazing would it be if we could actually get

the camera on the head?

But before the team could try this ambitious plan

on the three young orphans,

they needed to test their design on a captive cheetah

with an easy-going nature.

Enter Pride - possibly the most relaxed cheetah in Africa.

Her keeper, Derek Van Heerden,

didn't think she'd object to trialling our head camera.

Chris designed a 3-D printed harness

fit for the heat of the African bush.

Cooling is a massive issue.

We didn't want to put something on their head which was going to,

you know, make them overheat.

So we've tried to have vent holes

here so you get air underneath the head.

And the way we've attached it to the cheetah's head is just using

this flexible, breathable neoprene.

Chris's design needed to be quick to deploy,

but easy for the cheetah to pull off if she wasn't happy.

I'm really excited to see what we're going to get.

But no-one knew how Pride would react.

Do you reckon...? Do you reckon that's all right, isn't it?

Seems pretty good.

No problem.

Once Chris was happy with the fit...

..Derek and I kept a close eye on how Pride was doing.

The key thing, really, is for this camera to not interfere

with any of her senses.

Just a couple of minutes with the camera on her head

-and she's forgotten all about it.

-Yeah.

It was encouraging to see how comfortable she looked,

and how relaxed she was with other cheetahs in her enclosure.

Oh, goodness me!

She gets a bit of a face-lick.

Wow.

-Such an intimate moment.

-Beautiful.

Certainly is amazing.

-Ah, that's lovely, look at that.

-That really is.

We had to be sure that Pride

could reach top speed while wearing the camera.

It wasn't long before she was off.

-There she is.

-Oh, whoa!

Really fast, there we go.

-Unbelievable.

-That's an explosive speed.

That thing is moving.

Look at this.

The footage was proof

that our camera wouldn't put a cheetah off its stride.

That's amazing, it really is excellent footage.

We were now ready to join our three young orphan cheetahs

as they learn to hunt.

The next animal presented Chris with a very different set of problems.

The wild baboons we wanted to film in South Africa

were extremely scared of people.

A camera test with them was out of the question.

So once again, Chris needed a body double.

We chose a group of hand-reared baboons in a sanctuary in Namibia.

They weren't timid.

In fact, quite the opposite.

It is quite unusual working conditions.

Ooh, ooh!

Before making his prototype, Chris studied the way baboons move.

In contrast to cheetahs, baboons move their heads all the time.

For more stable shots,

the camera would have to be worn around the neck.

But this posed another problem

due to the baboons' distinctive facial features.

What I noticed is that their faces are very long.

I'm quite concerned that the chin might get in the shot.

But really, we've just got to try it now and see what we get.

Testing was easier said than done.

Are you going to wear a camera?

The baboons might be used to people...

Pff! OK.

Um, hmm...

..but they weren't used to wearing collars.

It's to sort of make it into a bit of a game.

Really don't want to annoy them or lose a finger.

Oh, no, he's got it!

Eventually, perseverance and patience paid off.

But, as Chris had feared,

the camera showed mostly chin.

Over the next few days, Chris experimented,

altering the position and angle of the camera to get the best results.

And finally...

..bingo!

You can see, you've got the bottom of the chin just here,

and the lens there.

So height-wise, it's kind of

just about there.

The prototype camera could deliver great footage.

But was it baboon-proof?

An adult male baboon can weigh 40 kilos...

and have canine teeth larger than a leopard's.

But there's no way that will be strong enough,

because a big wild male will just do that straight away.

The last step was to add serious reinforcement -

a stronger housing, and a thicker collar.

Feels pretty much perfect.

Now Chris's baboon cams had to work out in the wild.

Once in South Africa,

getting the cameras onto the baboons was fairly straightforward.

There we go!

Here, the biggest challenge...

..was getting the cameras back.

Each was set to drop off after two days filming.

In such dense scrub, Leah's only chance of finding the camera

was to track the baboon using the transmitter in its collar.

But baboons have no respect for human boundaries.

With its camera just about to drop off,

our baboon went trespassing on a neighbouring farm.

We saw the baboon with the collar on, with the camera,

crossing the road.

So she's just the other side of this fence now.

Without permission to enter,

Leah couldn't follow the baboon any further.

It's 4.55, so her collar

will be dropping off in five minutes.

Bang on time, the camera dropped off.

The battery in the tracking device would soon be dead.

Finally, Leah got the go-ahead to enter the farm.

It was now a race to find the camera

before the battery and the daylight ran out.

It's getting louder.

I think it's that way.

And just as night was closing in...

Oh, there it is!

Ah, yes.

Ah.

We've got the collar.

I'm so happy.

Next time...

We dive into the Atlantic Ocean

to reveal a secret gathering of giant devil rays.

These are unbelievably privileged views.

In the mountains of Turkey,

we are with brown bears, where tensions are running high.

-Ooh.

-Oh, wow!

And in France, we discover what happens

when dogs come face to face with wolves.
