0:00:02 > 0:00:03GROWLS
0:00:03 > 0:00:07As a wildlife cameraman, I have travelled the world,
0:00:07 > 0:00:11trying to capture life's most intimate and dramatic moments.
0:00:14 > 0:00:18But wouldn't it be incredible if we could see the world
0:00:18 > 0:00:20from an animal's point of view?
0:00:22 > 0:00:26Well, in this series, that is exactly what we're going to do,
0:00:26 > 0:00:28with the help of the animals themselves.
0:00:28 > 0:00:30They're going to be the ones that are doing the filming.
0:00:30 > 0:00:35They're going to take us to places that a cameraman like me
0:00:35 > 0:00:38simply cannot go,
0:00:38 > 0:00:42and reveal a side of their lives like we have never seen before.
0:00:50 > 0:00:52Working with scientists,
0:00:52 > 0:00:56we're designing cameras small enough to take us into their hidden world
0:00:56 > 0:00:58for the first time.
0:00:58 > 0:01:02- We're heading in.- Wow. Barging past some pups.
0:01:03 > 0:01:08Our camera crew is one of the most diverse teams to ever film
0:01:08 > 0:01:09a wildlife series.
0:01:11 > 0:01:14From 30-centimetre tall meerkats...
0:01:16 > 0:01:19..to 60mph cheetahs.
0:01:21 > 0:01:23From free diving fur seals...
0:01:25 > 0:01:27..to nest-building chimps.
0:01:29 > 0:01:33Our unconventional film crew are revealing surprising behaviour
0:01:33 > 0:01:37and giving us new insights into how they live their lives.
0:01:39 > 0:01:41- Wow.- That's really cool.
0:01:41 > 0:01:44Instantly, you get a real chimp point of view.
0:01:45 > 0:01:50This is their world, their footage.
0:01:50 > 0:01:52- Oh, yeah, look.- Wow!
0:01:52 > 0:01:53Their story.
0:01:55 > 0:01:58And we're going to see it through their eyes.
0:02:00 > 0:02:03She's definitely got her game face on.
0:02:14 > 0:02:17In this programme, our cameras reveal the hidden lives
0:02:17 > 0:02:20of three very different families.
0:02:22 > 0:02:26In Australia's shark-infested waters,
0:02:26 > 0:02:29we discover how fur seals escape from the deadly jaws
0:02:29 > 0:02:33of one of the ocean's top predators.
0:02:33 > 0:02:35Oh, wow. Goodness me.
0:02:36 > 0:02:41In South Africa, we see the conflict between baboons and local farmers.
0:02:43 > 0:02:48With tensions mounting, could our cameras help find a solution?
0:02:48 > 0:02:50The cameras are basically my last hope.
0:02:53 > 0:02:58But my adventure begins in the wilds of Namibia.
0:03:01 > 0:03:06This is a stronghold for Africa's most endangered big cat,
0:03:06 > 0:03:09the cheetah.
0:03:12 > 0:03:16Famously, cheetahs are spectacular sprint predators,
0:03:16 > 0:03:20chasing down their prey over the open savannah.
0:03:20 > 0:03:22That's how I've seen them in the past.
0:03:23 > 0:03:28In the open grassland, it's easy to watch these incredible athletes.
0:03:31 > 0:03:35But, here in Namibia, they live in bushland,
0:03:35 > 0:03:37where they're much harder to see.
0:03:42 > 0:03:44We're hoping our cameras can help us
0:03:44 > 0:03:48follow the lives of three very special young cheetahs.
0:03:53 > 0:03:56Conservationist Marlice Van Vuuren adopted this trio
0:03:56 > 0:03:59when they were orphaned at just one day old.
0:04:01 > 0:04:04They still rely on Marlice for food,
0:04:04 > 0:04:08but she wants to find out if they can catch their own prey.
0:04:08 > 0:04:09Come.
0:04:09 > 0:04:11Come!
0:04:11 > 0:04:12Come.
0:04:13 > 0:04:17She's hoping our cameras could help her track their progress
0:04:17 > 0:04:21as they learn to hunt in this dense scrubland.
0:04:24 > 0:04:27Who are your friends?
0:04:27 > 0:04:30- This is Odyssey.- You're beautiful.
0:04:30 > 0:04:32- Male?- Yeah, he's a boy.
0:04:32 > 0:04:34- OK.- He's a male.- What about the other two?
0:04:34 > 0:04:36They're two females, Shiloh and Wonder.
0:04:37 > 0:04:41Odyssey and his sisters are now 18 months old.
0:04:43 > 0:04:48By now, most wild cheetahs would be making their own kills.
0:04:49 > 0:04:52But these orphans have had no-one to teach them.
0:04:54 > 0:04:57Can they work out how to hunt for themselves?
0:05:00 > 0:05:04So, going to show you what we've come up with.
0:05:04 > 0:05:06- This is the camera.- Oh, OK.
0:05:06 > 0:05:08- Feel the... Feel the weight.- Yeah.
0:05:08 > 0:05:09And this goes on the head?
0:05:09 > 0:05:11On the head. What do you think?
0:05:11 > 0:05:14I would love to see the footage out of this.
0:05:14 > 0:05:16And it's nice that it's nice and elastic,
0:05:16 > 0:05:19and it's not going to restrict them at all,
0:05:19 > 0:05:20so I think it will work.
0:05:22 > 0:05:24The cameras look good to us,
0:05:24 > 0:05:29but the youngsters will decide if they're happy to wear them.
0:05:29 > 0:05:31- Who is this? Is this Odyssey? - This is Odyssey.- OK.
0:05:31 > 0:05:33The one that sits down.
0:05:33 > 0:05:34Hey, Odyssey.
0:05:34 > 0:05:39Odyssey's sister, Wonder, is first up for a fitting.
0:05:40 > 0:05:41Camera's running.
0:05:42 > 0:05:47I keep one part of my shirt clean, so I can clean the lenses.
0:05:47 > 0:05:49OK. That's perfect.
0:05:49 > 0:05:51- Look at you.- Look at you!
0:05:53 > 0:05:55Well, she's not upset,
0:05:55 > 0:05:59otherwise she would immediately start clawing and stop purring.
0:05:59 > 0:06:01She's happy.
0:06:01 > 0:06:06I'm their mum. To see what they actually do when I'm not there,
0:06:06 > 0:06:08it would make me very proud to know
0:06:08 > 0:06:10that they're actually doing very good.
0:06:10 > 0:06:12Huh? Hello.
0:06:13 > 0:06:16You want one? He's asking, "Where's mine?"
0:06:16 > 0:06:20It's all the latest thing amongst cheetahs in this part of the world.
0:06:22 > 0:06:24Don't worry, no stress.
0:06:24 > 0:06:27There we go. You are... There we go.
0:06:27 > 0:06:30- Quite a couple.- Yeah. With new bling.- You happy with that?
0:06:30 > 0:06:32They've got Bushveld bling.
0:06:35 > 0:06:38With two of the three cats wearing cameras,
0:06:38 > 0:06:41we watch them head into the bush.
0:06:43 > 0:06:45They're soon out of our sight,
0:06:45 > 0:06:49but the cameras are filming their every move.
0:06:52 > 0:06:57I don't know about you, but I'm very excited we're seeing this.
0:06:57 > 0:06:58OK, here we go.
0:07:01 > 0:07:02Wow.
0:07:02 > 0:07:05That's quite incredible.
0:07:05 > 0:07:08That's what it looks like to be a cheetah.
0:07:11 > 0:07:13- Oh, he's rolling around. - That's fantastic.
0:07:16 > 0:07:18You can see, they're just kind of chilling out,
0:07:18 > 0:07:20enjoying being together.
0:07:24 > 0:07:30This is an intimate insight into the cheetahs' lives.
0:07:31 > 0:07:33Oh...
0:07:33 > 0:07:35Watch the camera.
0:07:36 > 0:07:38Head shake.
0:07:41 > 0:07:44While Odyssey takes a drink,
0:07:44 > 0:07:48Wonder finds a good scratching post.
0:07:55 > 0:07:58And it's not long before our playful young cheetahs
0:07:58 > 0:08:00decide to stretch their legs.
0:08:04 > 0:08:08And we're running with the fastest mammal on Earth.
0:08:19 > 0:08:22- Oh, wow.- Yes, it's beautiful. Look at the tail.
0:08:22 > 0:08:24Wow. That is stunning.
0:08:24 > 0:08:25Absolutely incredible.
0:08:28 > 0:08:29Oh, look at that.
0:08:37 > 0:08:41It's an amazing insight into the youngsters' lives.
0:08:43 > 0:08:45But what we really want to know
0:08:45 > 0:08:47is whether they can hunt for themselves.
0:08:50 > 0:08:54Hopefully, the cameras will give us the answer.
0:08:55 > 0:08:59I'll also try to film them for as long as I can.
0:09:13 > 0:09:16Trying to spot the three cheetahs.
0:09:16 > 0:09:18They've gone into this very thick bush,
0:09:18 > 0:09:20and...
0:09:20 > 0:09:23I don't know where they are.
0:09:23 > 0:09:25None of them. Any of them.
0:09:25 > 0:09:27They're all gone.
0:09:29 > 0:09:33It's only when Odyssey emerges from the dense cover
0:09:33 > 0:09:35that I finally find him.
0:09:37 > 0:09:40Or, really, it's more a case of him finding me.
0:09:43 > 0:09:44Hey, beautiful.
0:09:46 > 0:09:50No, no, no, no. OK, I think you're going to jump up onto the car.
0:09:50 > 0:09:52To get a better view.
0:09:52 > 0:09:53OK, that's fine.
0:09:54 > 0:09:56With this gain in height,
0:09:56 > 0:10:01Odyssey can see so much more than he can see
0:10:01 > 0:10:03when he's down on the ground.
0:10:03 > 0:10:06So this isn't about a cheetah coming to say hello to us,
0:10:06 > 0:10:09it's about just kind of having a better field of view.
0:10:12 > 0:10:14Maybe saying hello as well.
0:10:19 > 0:10:22That's not what you're supposed to be doing.
0:10:22 > 0:10:24You going to go hunting?
0:10:24 > 0:10:25Where's your sisters?
0:10:25 > 0:10:28There's no room in the back, if that's what you're thinking.
0:10:30 > 0:10:34Odyssey's not showing much sign of independence just yet.
0:10:38 > 0:10:42But he does finally head off to rejoin his sisters.
0:10:44 > 0:10:47They've spotted a herd of gemsbok in a clearing.
0:10:49 > 0:10:53For young cheetahs, these are a very dangerous target.
0:10:58 > 0:11:00Three cats altogether.
0:11:01 > 0:11:03They look like a force to be reckoned with.
0:11:08 > 0:11:11I don't quite know how this is going to play out.
0:11:11 > 0:11:15I have seen cheetahs hunt before, but out in the open plains,
0:11:15 > 0:11:17and I'm not sure how it's going to change their behaviour,
0:11:17 > 0:11:20somewhere as thick as this. It's very, very scrubby and bushy.
0:11:20 > 0:11:24OK, cheetah there, moving in.
0:11:24 > 0:11:26Right.
0:11:27 > 0:11:29OK, one's running.
0:11:29 > 0:11:30Second one running.
0:11:30 > 0:11:31Towards the game.
0:11:32 > 0:11:35They don't yet know that the cheetahs are gaining on them.
0:11:35 > 0:11:36They're actually just...
0:11:38 > 0:11:41OK, full-on run from the front cheetah, a full-on run.
0:11:42 > 0:11:44No, they're just scattering the herd.
0:11:45 > 0:11:47The gemsbok panic.
0:11:51 > 0:11:54The cheetahs are after an easy target.
0:11:56 > 0:11:58OK. Oh!
0:11:58 > 0:12:00Confusion, confusion.
0:12:02 > 0:12:06It's very hard trying to keep track of three cheetahs.
0:12:09 > 0:12:12Wonder's camera captures what I can't see.
0:12:13 > 0:12:17She's chasing one animal away from the group.
0:12:21 > 0:12:24In amongst the bushes, Wonder's losing speed.
0:12:25 > 0:12:29Her sister Shiloh charges in on the left,
0:12:29 > 0:12:33but the gemsbok is now so far ahead, it's safe.
0:12:40 > 0:12:45The thick vegetation has scuppered our cheetahs' chances.
0:12:51 > 0:12:54Wonder skulks back to the clearing,
0:12:54 > 0:12:57where the tables have turned.
0:13:06 > 0:13:11Oh, just got charged by a big, big gemsbok there.
0:13:13 > 0:13:17They're now at risk of being skewered by this large male.
0:13:26 > 0:13:30The prey knows that the predator is around -
0:13:30 > 0:13:32the cheetah have lost their advantage.
0:13:34 > 0:13:35Ah!
0:13:35 > 0:13:37Now they're just getting chased away,
0:13:37 > 0:13:40they're being humiliated.
0:13:44 > 0:13:50Taking on such a large prey was a real rookie mistake.
0:13:52 > 0:13:56But will they learn from the experience?
0:14:17 > 0:14:20Over the next few days, the cameras keep rolling.
0:14:24 > 0:14:28The youngsters need to turn this scrubby terrain to their advantage.
0:14:33 > 0:14:36And soon, we see encouraging signs.
0:14:40 > 0:14:44The three cheetahs are following animal trails in the undergrowth.
0:14:45 > 0:14:49Shiloh appears to sniff the ground, to work out what prey is around.
0:14:52 > 0:14:53See, this is impossible.
0:14:53 > 0:14:56- There's absolutely no way we could see this any other way.- Uh-huh.
0:14:59 > 0:15:03They're also using the thick bush as cover.
0:15:04 > 0:15:07The closer they can get to the prey,
0:15:07 > 0:15:11the more likely they are to make a kill.
0:15:11 > 0:15:13- They're trying to get eyes on.- Hm.
0:15:15 > 0:15:18Odyssey creeps forward.
0:15:20 > 0:15:22He spots the target
0:15:22 > 0:15:24and freezes.
0:15:24 > 0:15:27So his sister's on his left, one of them.
0:15:27 > 0:15:29That's a clear sign that they're working together,
0:15:29 > 0:15:32because he sees the prey, stops, checks his sister's there.
0:15:32 > 0:15:35- And then he's looking back to the prey.- Yeah.
0:15:35 > 0:15:36And there he goes.
0:15:37 > 0:15:39Oh, my God!
0:15:44 > 0:15:48Oh! It's a youngster.
0:15:48 > 0:15:49My God!
0:15:49 > 0:15:51One of his sisters is in front.
0:15:51 > 0:15:53It's a baby. It's a baby eland.
0:15:53 > 0:15:55Yeah.
0:15:55 > 0:15:57Look at that. Oh, my gosh.
0:15:58 > 0:16:02His sister, Shiloh, tries to trip the calf.
0:16:04 > 0:16:06Oh, so close.
0:16:06 > 0:16:08Oh, my goodness me.
0:16:08 > 0:16:10What on Earth?
0:16:10 > 0:16:13Odyssey is forced to swerve to avoid a thorn bush.
0:16:14 > 0:16:18Could you see the difficulties of negotiating those bushes?
0:16:21 > 0:16:24And now the mum's trying to keep them away.
0:16:24 > 0:16:27- There she goes. - My heart is in my mouth.
0:16:27 > 0:16:29That is quite something.
0:16:32 > 0:16:36A cheetah can only sprint at top speed for ten seconds,
0:16:36 > 0:16:42so the eland and her calf manage to escape.
0:16:42 > 0:16:45I'm completely blown away by these images.
0:16:45 > 0:16:47- It's brilliant to follow them.- Hm.
0:16:47 > 0:16:49What are they actually doing in the Veld?
0:16:49 > 0:16:52- Yeah.- You know, and I'm proud as the mum of them.
0:16:52 > 0:16:54You know, they're actually working in a team
0:16:54 > 0:16:57and they... They have huge challenges, and they take it.
0:16:57 > 0:17:01They're not scared. So this is amazing, this is really a good idea.
0:17:02 > 0:17:06But Marlice has yet to see a successful hunt.
0:17:08 > 0:17:10We leave our cameras with her,
0:17:10 > 0:17:12to keep watch on the youngsters' progress.
0:17:20 > 0:17:25For our next mission, I'm travelling to the south coast of Australia,
0:17:25 > 0:17:29to the remote and rugged Kanowna Island.
0:17:31 > 0:17:35Few animals have what it takes to survive out here,
0:17:35 > 0:17:38but there's one hardy sea mammal that does.
0:17:47 > 0:17:49The island itself is more of a rocky outcrop.
0:17:49 > 0:17:53It's uninhabited but for the thousands of fur seals
0:17:53 > 0:17:55that call it home.
0:17:56 > 0:17:59On the island, the fur seals are safe.
0:18:01 > 0:18:04But the surrounding seas
0:18:04 > 0:18:06are deadly...
0:18:08 > 0:18:13Teeming with the ocean's most feared predator,
0:18:13 > 0:18:15the great white shark.
0:18:20 > 0:18:23I'm here to help scientists to discover
0:18:23 > 0:18:25how fur seals avoid the sharks
0:18:25 > 0:18:29and thrive in this unforgiving wilderness.
0:18:34 > 0:18:38We're hoping our cameras will help solve the puzzle.
0:18:39 > 0:18:41There it is.
0:18:41 > 0:18:42Home, sweet home.
0:18:46 > 0:18:50Leading the research team is Professor John Arnold.
0:18:54 > 0:18:55- Hello.- Gordon.
0:18:55 > 0:18:58- Nice to meet you.- What an amazing, amazing place.
0:18:58 > 0:18:59- Thank you.- Good to meet you.
0:18:59 > 0:19:04For the next week, this windswept spot will be my home.
0:19:04 > 0:19:07Oh, perfect. Everything a man needs.
0:19:09 > 0:19:14John's team have been studying the seals for 20 years.
0:19:14 > 0:19:18But their lives out at sea are still shrouded in mystery.
0:19:21 > 0:19:25So what are the big questions you want to be answered
0:19:25 > 0:19:27by the seals taking cameras with them?
0:19:27 > 0:19:29They spend up to 80% of their lives at sea.
0:19:29 > 0:19:31Every time their mothers leave the colony,
0:19:31 > 0:19:34they have to run the gauntlet of any sharks that are out there.
0:19:34 > 0:19:35What are they doing?
0:19:35 > 0:19:39Just seeing them on shore gives us a very small view of their life.
0:19:39 > 0:19:43The big Holy Grail for us, is what are they seeing?
0:19:43 > 0:19:44What are they hunting?
0:19:44 > 0:19:47How successful they are at catching prey...
0:19:47 > 0:19:49It's a hard life for these seals.
0:19:52 > 0:19:56There are around 15,000 fur seals on Kanowna Island...
0:19:59 > 0:20:04..so it's no surprise that the island's a magnet for great whites.
0:20:05 > 0:20:11These giant sharks specialise in hunting marine mammals like seals.
0:20:14 > 0:20:17Our first challenge will be to test our cameras.
0:20:19 > 0:20:23John's been fitting seals with trackers for years.
0:20:24 > 0:20:27He operates with military precision.
0:20:32 > 0:20:34His tactic is to keep low...
0:20:34 > 0:20:37I'm going to sneak in, see what I can find.
0:20:37 > 0:20:40Okey-dokey. ..keep quiet...
0:20:40 > 0:20:43and bring a very large net.
0:20:51 > 0:20:54OK, we've got her.
0:20:54 > 0:20:57Let me know if there's anything I can do.
0:20:57 > 0:21:01Our mother seal gets a light anaesthetic to help keep her calm.
0:21:02 > 0:21:06- Wow.- 86.0, plus board, so she's 80 kilos.
0:21:09 > 0:21:11At such a healthy size,
0:21:11 > 0:21:14John's happy that she won't be hampered by a small camera.
0:21:14 > 0:21:16- OK.- Well done.
0:21:16 > 0:21:17Go back.
0:21:19 > 0:21:22While our mum goes on her first filming trip...
0:21:24 > 0:21:28..I want to see what the seals get up to close to shore.
0:21:42 > 0:21:47The theory is that this spot is too shallow for sharks.
0:21:49 > 0:21:53It's the seal equivalent of a paddling pool,
0:21:53 > 0:21:57a safe and sheltered spot where pups can learn to swim.
0:22:10 > 0:22:14That is absolutely beautiful.
0:22:14 > 0:22:18It is probably one of the nicest things I've ever seen underwater.
0:22:19 > 0:22:21This cove is the only place
0:22:21 > 0:22:24I can observe these seals beneath the waves.
0:22:24 > 0:22:27But we want to understand their lives
0:22:27 > 0:22:29away from the sheltered shallows.
0:22:31 > 0:22:34And that's what the deployment of these cameras is all about.
0:22:38 > 0:22:42Our camera testing seal has also been taking a dip.
0:22:44 > 0:22:47Time to see what the footage reveals.
0:22:51 > 0:22:53Heading down to sea.
0:22:54 > 0:22:57See the way her shoulder blades are working.
0:22:59 > 0:23:01And she's about to jump into the water.
0:23:01 > 0:23:04There she goes. Into the...
0:23:04 > 0:23:06Wow. Oh, wow!
0:23:06 > 0:23:07Look at that!
0:23:10 > 0:23:16As soon as she dives, the camera captures unexpected behaviour.
0:23:17 > 0:23:19Oh, look at that. Look at that.
0:23:21 > 0:23:22She's rubbing against the rocks.
0:23:22 > 0:23:23Oh, yeah.
0:23:23 > 0:23:25On that green stuff.
0:23:34 > 0:23:37- They are rubbing...- Wow, yeah, you can see it very clearly there.
0:23:37 > 0:23:39Yeah.
0:23:39 > 0:23:42And now she's rubbing the side of her face, her neck.
0:23:44 > 0:23:47The other animals around her are doing the same thing.
0:23:47 > 0:23:48- They're all doing it.- Yeah.
0:23:49 > 0:23:52- And you've never seen this before? - No, I wouldn't have known.
0:23:52 > 0:23:56I mean, you see them offshore at the surface, playing.
0:23:56 > 0:23:59This is brand-new stuff. I've never seen this before.
0:23:59 > 0:24:01Wow!
0:24:06 > 0:24:10John thinks the seals could be using the seaweed to clean their fur...
0:24:13 > 0:24:16..brushing up against it to remove parasites.
0:24:27 > 0:24:31Already, we've captured brand-new behaviour.
0:24:32 > 0:24:34We deploy more cameras.
0:24:36 > 0:24:40Hopefully, these seals will head further out to sea.
0:24:44 > 0:24:48We know from John's previous research that some seals will travel
0:24:48 > 0:24:50as far as Tasmania...
0:24:52 > 0:24:54..a 200-mile round trip.
0:25:01 > 0:25:03But they face the greatest danger
0:25:03 > 0:25:06from sharks within the first few miles of their journey.
0:25:12 > 0:25:14There she goes.
0:25:18 > 0:25:22Will our cameras finally reveal the seals' survival strategy?
0:25:24 > 0:25:28You see seals coming ashore with injuries from sharks.
0:25:28 > 0:25:31- They're the lucky ones that got away.- Mm-hmm.
0:25:36 > 0:25:41As soon as our seal enters the danger zone,
0:25:41 > 0:25:44she heads straight down to the bottom.
0:25:46 > 0:25:48It's a deliberate tactic.
0:25:51 > 0:25:56Great whites prefer to ambush prey from below.
0:25:57 > 0:26:00She's trying to slip under the shark's radar.
0:26:08 > 0:26:11She can hold her breath for eight minutes...
0:26:14 > 0:26:16..but then she must come up for air,
0:26:16 > 0:26:20and this is when she's most vulnerable.
0:26:28 > 0:26:32Now, she starts to swim in a completely different way.
0:26:32 > 0:26:36All the time when she's coming towards the surface,
0:26:36 > 0:26:38she's looking around. A 360 view.
0:26:41 > 0:26:43In these dangerous surface waters,
0:26:43 > 0:26:47she's doing everything she can to avoid a surprise attack.
0:26:49 > 0:26:52Rotating her head gives her an all-round view.
0:26:54 > 0:26:57Just constantly barrelling and it's just twisting and turning,
0:26:57 > 0:26:59it's incredible.
0:26:59 > 0:27:03- You wouldn't know that unless you had a camera on an animal.- Yeah.
0:27:07 > 0:27:11As soon as she can, she returns to the safety of the sea bed.
0:27:13 > 0:27:18This is the first time John has ever seen how seal mums
0:27:18 > 0:27:20give sharks the slip.
0:27:22 > 0:27:26Further out, she switches into hunting mode.
0:27:28 > 0:27:31Skimming over the sea floor has another benefit.
0:27:33 > 0:27:35She's onto something.
0:27:35 > 0:27:36It's a cuttlefish.
0:27:40 > 0:27:42Wow!
0:27:42 > 0:27:44Look at that!
0:27:44 > 0:27:47- That's a big one. - Like a big plate of ink.
0:27:49 > 0:27:54The cuttlefish squirts ink to try and confuse the seal...
0:27:55 > 0:27:57Wow.
0:27:57 > 0:28:00..but it's too late.
0:28:13 > 0:28:15I don't know if we've seen cuttlefish in their diet before.
0:28:15 > 0:28:17Really?
0:28:20 > 0:28:2618 metres down, her super senses soon detect something else.
0:28:30 > 0:28:32Oh, what's she chasing here?
0:28:39 > 0:28:40Oh...
0:28:40 > 0:28:42- It's big.- Oh, yeah.
0:28:42 > 0:28:43It's a big octopus.
0:28:43 > 0:28:45See it, it's the tentacles.
0:28:45 > 0:28:48- Yeah.- I didn't even see her grab that.
0:28:48 > 0:28:51A struggling octopus is hard to eat.
0:28:56 > 0:29:00Our seal risks heading to the surface.
0:29:00 > 0:29:05Up here, she kills her prey and bashes it into bite-sized chunks.
0:29:09 > 0:29:11Wow.
0:29:11 > 0:29:13At the same time she's doing that,
0:29:13 > 0:29:15- she's having to keep an eye out for sharks.- Yeah.
0:29:17 > 0:29:20The cameras have revealed how mothers specialise in hunting
0:29:20 > 0:29:22on the sea floor.
0:29:25 > 0:29:27But when this seal comes up for air,
0:29:27 > 0:29:31something else catches her attention.
0:29:31 > 0:29:32Is that dolphins?
0:29:32 > 0:29:35- Yeah.- Oh, wow. Wow, wow, wow!
0:29:35 > 0:29:36Goodness me!
0:29:36 > 0:29:39She's come across a bunch of dolphins feeding in the bay pool.
0:29:39 > 0:29:41Oh, you can see her snatching them there.
0:29:41 > 0:29:44Wow, that's incredible.
0:29:44 > 0:29:47So, the presence of those dolphins is going to help her.
0:29:47 > 0:29:49Well, I think she's just getting a free meal here.
0:29:51 > 0:29:53The dolphins are rounding up the fish,
0:29:53 > 0:29:56and the seal dives in for an easy meal.
0:30:01 > 0:30:02- The...- Oh, there's another one.
0:30:02 > 0:30:04Wow, that's incredible!
0:30:06 > 0:30:08Without the onboard cameras,
0:30:08 > 0:30:13John would have no idea these seals take advantage of dolphins.
0:30:21 > 0:30:25But once the dolphins leave, the fish spread out.
0:30:27 > 0:30:30A lone seal can't keep them bunched together.
0:30:35 > 0:30:37We see here that she's working really hard
0:30:37 > 0:30:38and there's a huge school
0:30:38 > 0:30:41of fish there, but she's getting very few of them.
0:30:43 > 0:30:48With a belly full of food, she heads back to the sea floor.
0:30:56 > 0:31:01These cameras have given us a remarkable insight into the lives
0:31:01 > 0:31:04of these seals far out at sea.
0:31:08 > 0:31:13For John, these insights have transformed his research.
0:31:14 > 0:31:18You've learned more from, say, a two-hour video
0:31:18 > 0:31:20of the animals underwater
0:31:20 > 0:31:22than years and years of dive recorders and GPS
0:31:22 > 0:31:26data logger tracking, because now you are seeing how they are behaving
0:31:26 > 0:31:28underwater in response to what they're seeing.
0:31:28 > 0:31:32Therefore, the cameras give us a brand-new view of their life.
0:31:42 > 0:31:46Now we're facing a very different challenge.
0:31:52 > 0:31:55On the other side of the world, there's trouble.
0:31:58 > 0:32:01War is raging in the South African bush...
0:32:04 > 0:32:08..between the local farmers and Chacma baboons.
0:32:13 > 0:32:17The baboons' natural habitat is shrinking,
0:32:17 > 0:32:20forcing them into farmland,
0:32:20 > 0:32:23where they damage and eat the farmers' crops.
0:32:28 > 0:32:31It's a battle that's threatening farmers' livelihoods.
0:32:34 > 0:32:39Raino just harvested his butternut squash,
0:32:39 > 0:32:42but half his crop was unsellable.
0:32:42 > 0:32:48All of these butternuts, basically, in the field is all damaged
0:32:48 > 0:32:51with bite marks, scratching marks.
0:32:51 > 0:32:54That's the way they carry on, take a bite from each one.
0:32:57 > 0:33:00Some farmers are already shooting baboons,
0:33:00 > 0:33:03so a solution can't come soon enough.
0:33:06 > 0:33:11Could cameras on the baboons reveal how to keep them off these crops?
0:33:14 > 0:33:18Scientist Leah Findlay has spent the last five years
0:33:18 > 0:33:20searching for answers.
0:33:20 > 0:33:22So far, nothing has worked.
0:33:24 > 0:33:28Baboons are very smart, they're very dexterous, agile.
0:33:28 > 0:33:32It's basically like having a pack of ninjas on your farm.
0:33:32 > 0:33:34Yeah, it's a pretty tricky problem to solve.
0:33:37 > 0:33:39We try everything to stop the baboons.
0:33:39 > 0:33:43In the beginning, we'd put branches, thorn trees around it.
0:33:43 > 0:33:44It never stopped them.
0:33:44 > 0:33:48We've tried rubber snakes, alarm systems.
0:33:48 > 0:33:52We've made proper scarecrows that move like this.
0:33:52 > 0:33:56Takes you about a week or so and then they're getting used to it.
0:33:56 > 0:33:59We've tried electric fences, guards.
0:33:59 > 0:34:01If the guards are walking on this side,
0:34:01 > 0:34:04they will be on the other side of the field.
0:34:05 > 0:34:06Then if she can run to that side,
0:34:06 > 0:34:09then they will cross all the way backwards,
0:34:09 > 0:34:10coming to this side again.
0:34:10 > 0:34:11They are very clever.
0:34:15 > 0:34:19These clever monkeys are not in the crop fields every day.
0:34:23 > 0:34:27For the last week, the baboons haven't been raiding,
0:34:27 > 0:34:30even though there are thousands of butternuts in the field.
0:34:40 > 0:34:44If Leah can learn what is keeping them away now,
0:34:44 > 0:34:48perhaps she can use it to keep them out permanently.
0:34:53 > 0:34:57At this stage, I think the cameras are basically my last hope,
0:34:57 > 0:34:59because I can't carry on like this.
0:34:59 > 0:35:06Now, we just need to get our custom-built camera
0:35:06 > 0:35:08onto a baboon.
0:35:08 > 0:35:09I'm stuck!
0:35:11 > 0:35:16Leah sets the trap, baited with the baboons' beloved butternut.
0:35:17 > 0:35:20When something pushes down on the table,
0:35:20 > 0:35:23it will pull the latch out and the door will slide shut.
0:35:30 > 0:35:34As night falls, we have our first baboon.
0:35:34 > 0:35:38A female. The vet anaesthetises her and fits the camera.
0:35:44 > 0:35:49Over the coming days, Leah catches and puts cameras on more baboons.
0:35:57 > 0:35:58There we go!
0:36:05 > 0:36:07As the new day dawns,
0:36:07 > 0:36:12we get our first glimpse into the lives of these secretive animals.
0:36:22 > 0:36:25They slept in the trees for safety.
0:36:27 > 0:36:30Now they're sunbathing to warm up.
0:36:53 > 0:36:56That's beautiful footage here.
0:36:59 > 0:37:01She's having a good look at it, isn't she?
0:37:01 > 0:37:04So, this is basically our eyes now.
0:37:04 > 0:37:07Whatever we see now, it's like through their eyes.
0:37:07 > 0:37:09Yeah.
0:37:09 > 0:37:11Considering this has only been on overnight,
0:37:11 > 0:37:14- she's not bothered by it, is she? - Nothing at all, not at all.
0:37:16 > 0:37:18This one is grooming her.
0:37:18 > 0:37:20Grooming is the way they socialise,
0:37:20 > 0:37:24- so I think she might be a more dominant female.- Hm.
0:37:28 > 0:37:32It's wonderful to finally see the baboons' world.
0:37:35 > 0:37:40But will this teach Leah and Raino how to keep them off the crops?
0:37:44 > 0:37:48- Fence.- Not even jumping over it, just going through it.
0:37:48 > 0:37:52Yeah, just straight through, she pulled it down and she went through.
0:37:52 > 0:37:54- It's like it's not even there. - These fences, to be honest,
0:37:54 > 0:37:56I don't think are going to stop them at all.
0:37:58 > 0:38:00My opinion!
0:38:01 > 0:38:04Does anything put the baboons off?
0:38:11 > 0:38:15One of our cameras gives us a clue.
0:38:18 > 0:38:20- And now they're running.- Yeah.
0:38:20 > 0:38:23- Because nice open area...- Yeah.
0:38:23 > 0:38:26Which suggests that they don't like being in it.
0:38:26 > 0:38:28That's definitely something that we can think about
0:38:28 > 0:38:30in terms of the crops.
0:38:32 > 0:38:35Leah thinks an empty space around the crops
0:38:35 > 0:38:38would be a better barrier than a fence.
0:38:40 > 0:38:43And soon, we get more inside information.
0:38:46 > 0:38:49The baboons are digging for water.
0:38:51 > 0:38:54It's dry season, so the rivers have dried up.
0:38:56 > 0:38:59But there is an easier way to get a drink.
0:39:00 > 0:39:04Why bother digging when there's a water trough?
0:39:06 > 0:39:08Has the camera gone under water?
0:39:08 > 0:39:10Yeah.
0:39:10 > 0:39:11Is it waterproof?!
0:39:11 > 0:39:13Has to be.
0:39:13 > 0:39:16It gives Leah another idea.
0:39:16 > 0:39:18I'm just thinking about, you know,
0:39:18 > 0:39:20keeping water points away from the crops,
0:39:20 > 0:39:24because maybe having our water close to the crops is, you know,
0:39:24 > 0:39:25drawing them in.
0:39:28 > 0:39:31And finally, we learn why the baboons
0:39:31 > 0:39:33aren't raiding at the moment.
0:39:36 > 0:39:38This is the first ever glimpse
0:39:38 > 0:39:41of what these baboons are eating in the wild.
0:39:43 > 0:39:45And it goes like this,
0:39:45 > 0:39:47it's basically every time they put a fruit in their mouth.
0:39:47 > 0:39:49Yeah, yeah.
0:39:49 > 0:39:51- At first...- Just shovelling it in, yeah.
0:39:53 > 0:39:56And it feels like she's going to feed you.
0:39:56 > 0:39:57Yeah!
0:40:02 > 0:40:05Same kind of fruit, that kind of roundish fruit tree.
0:40:05 > 0:40:07Yeah, yeah.
0:40:07 > 0:40:09This fruit could be the key.
0:40:09 > 0:40:11It's from an alala palm.
0:40:12 > 0:40:17They take up to four years to ripen and fall to the ground.
0:40:17 > 0:40:20And when they do, there are thousands of them.
0:40:23 > 0:40:25It's a feast.
0:40:25 > 0:40:29The baboons are choosing this wild fruit over the butternuts.
0:40:34 > 0:40:36When there's enough feeding and stuff,
0:40:36 > 0:40:39they prefer to use their natural food.
0:40:39 > 0:40:43- When there's plenty out there, they don't come in.- Yeah.
0:40:50 > 0:40:54You could plant more of these trees that have their natural food
0:40:54 > 0:40:57that maybe they prefer. You know, that might be an option.
0:41:00 > 0:41:04The peak time for crop raiding is the dry season,
0:41:04 > 0:41:06when there is little other food around.
0:41:08 > 0:41:13If Raino could plant bushes and trees that fruit in the dry season,
0:41:13 > 0:41:16it might get the baboons through this hunger gap
0:41:16 > 0:41:18and keep them off his fields.
0:41:21 > 0:41:23Our cameras reveal a wide range
0:41:23 > 0:41:26of the baboons' favourite fruit and berries,
0:41:26 > 0:41:29showing Raino exactly what to plant.
0:41:31 > 0:41:33I think we've definitely learned some new things.
0:41:33 > 0:41:35We've learned a lot, yeah.
0:41:41 > 0:41:44Does this make you feel any differently about the baboons?
0:41:44 > 0:41:46Having a baboon's-eye view?
0:41:46 > 0:41:48- Feeling more sorry for them, actually.- Oh, really?- Yeah.
0:41:50 > 0:41:53- Why's that?- It's their natural environment,
0:41:53 > 0:41:55so there has to be space for everybody.
0:41:58 > 0:42:03Leah has gained new insights into the feeding habits of the baboons.
0:42:03 > 0:42:09These will be crucial to her effort to solve this tricky conflict,
0:42:09 > 0:42:13finding a peaceful way for farmers
0:42:13 > 0:42:17and baboons to coexist.
0:42:32 > 0:42:36Back in Namibia, 700 miles away,
0:42:36 > 0:42:40we've been putting our cameras on three orphaned cheetahs.
0:42:40 > 0:42:42- OK.- Fantastic, there we go.
0:42:42 > 0:42:45Their surrogate mum, Marlice,
0:42:45 > 0:42:48wants to know if they can hunt for themselves in the bush.
0:42:50 > 0:42:53We've seen some encouraging signs...
0:42:54 > 0:42:55Oh, she's seen something.
0:42:55 > 0:42:58They're all up on their feet looking off in that direction.
0:42:58 > 0:42:59I can't see what they can see.
0:43:01 > 0:43:05..but until now, the cameras have captured near misses.
0:43:06 > 0:43:08No successful hunts.
0:43:20 > 0:43:24Several months on, Marlice is still using her cameras
0:43:24 > 0:43:26to see how their hunting is coming on.
0:43:29 > 0:43:32Odyssey flushes a warthog.
0:43:34 > 0:43:37A warthog is one of the animals that they are most scared of.
0:43:41 > 0:43:44The tusks on these powerful pigs can kill.
0:43:49 > 0:43:53Just in time, he realises it's a mistake to follow a warthog
0:43:53 > 0:43:55into the bush.
0:43:57 > 0:43:59- SHE CHUCKLES - He did give up.
0:44:02 > 0:44:03A bat-eared fox...
0:44:12 > 0:44:13It's just amazing that...
0:44:13 > 0:44:16I mean, I didn't even know that they go for bat-eared foxes,
0:44:16 > 0:44:18if it wasn't for the camera.
0:44:21 > 0:44:25Shiloh and Wonder move in from each side...
0:44:26 > 0:44:29..and the cameras capture their deadly strike.
0:44:30 > 0:44:33With the cameras and with technology like this,
0:44:33 > 0:44:37it just proves that actually without a mum,
0:44:37 > 0:44:40without an adult showing them how to do it, and with opportunities,
0:44:40 > 0:44:42they can actually learn.
0:44:44 > 0:44:48By working together, they're becoming a formidable hunting trio.
0:44:49 > 0:44:52And their choice of prey is getting better.
0:45:04 > 0:45:07Springbok are one of the fastest of all African animals.
0:45:12 > 0:45:16But up against cheetahs, this one has little chance of escape.
0:45:26 > 0:45:28Success at last.
0:45:28 > 0:45:31The right prey and the perfect technique.
0:45:33 > 0:45:34I can see that they are ready.
0:45:34 > 0:45:36They've learned a lot,
0:45:36 > 0:45:39they are ready and they're working in coalition.
0:45:39 > 0:45:44It's two females and a male together and making their hunt successful.
0:45:44 > 0:45:48It helps me to kind of cut the umbilical cord and know
0:45:48 > 0:45:51that they actually, really, they can go.
0:45:51 > 0:45:54Yeah, it's really impressive to see and I'm so proud of them.
0:45:58 > 0:46:01Our cameras have given us an insight
0:46:01 > 0:46:04that otherwise would be impossible to see.
0:46:04 > 0:46:06And it's the cheetahs themselves
0:46:06 > 0:46:10that have given us their view of their world.
0:46:10 > 0:46:14They have taken us with them deep into the African bush.
0:46:15 > 0:46:19The cameras have shown Marlice that her three young cubs
0:46:19 > 0:46:21can fend for themselves.
0:46:28 > 0:46:32And our new insights into the lives of cheetahs
0:46:32 > 0:46:37could help us to better protect these incredible big cats.
0:46:58 > 0:46:59In this episode,
0:46:59 > 0:47:01two very different African animals
0:47:01 > 0:47:05presented us with two very different problems.
0:47:06 > 0:47:10How to fit a camera onto the superfast cheetah...
0:47:12 > 0:47:14..and the super-shy baboon.
0:47:17 > 0:47:22It was up to mini camera expert Chris Watts to find the solutions.
0:47:22 > 0:47:26When I first think about making a camera system for an animal,
0:47:26 > 0:47:30a lot of it is kind of really studying how they move.
0:47:30 > 0:47:32And with the cheetah, the first thing you notice
0:47:32 > 0:47:35is that the head is so stable when they're moving and running,
0:47:35 > 0:47:37the head is just completely locked.
0:47:38 > 0:47:41And we all thought, how amazing would it be if we could actually get
0:47:41 > 0:47:42the camera on the head?
0:47:44 > 0:47:47But before the team could try this ambitious plan
0:47:47 > 0:47:49on the three young orphans,
0:47:49 > 0:47:53they needed to test their design on a captive cheetah
0:47:53 > 0:47:55with an easy-going nature.
0:47:55 > 0:48:00Enter Pride - possibly the most relaxed cheetah in Africa.
0:48:03 > 0:48:05Her keeper, Derek Van Heerden,
0:48:05 > 0:48:08didn't think she'd object to trialling our head camera.
0:48:14 > 0:48:17Chris designed a 3-D printed harness
0:48:17 > 0:48:19fit for the heat of the African bush.
0:48:21 > 0:48:22Cooling is a massive issue.
0:48:22 > 0:48:25We didn't want to put something on their head which was going to,
0:48:25 > 0:48:27you know, make them overheat.
0:48:27 > 0:48:29So we've tried to have vent holes
0:48:29 > 0:48:32here so you get air underneath the head.
0:48:32 > 0:48:35And the way we've attached it to the cheetah's head is just using
0:48:35 > 0:48:37this flexible, breathable neoprene.
0:48:39 > 0:48:41Chris's design needed to be quick to deploy,
0:48:41 > 0:48:45but easy for the cheetah to pull off if she wasn't happy.
0:48:48 > 0:48:50I'm really excited to see what we're going to get.
0:48:51 > 0:48:54But no-one knew how Pride would react.
0:48:59 > 0:49:02Do you reckon...? Do you reckon that's all right, isn't it?
0:49:02 > 0:49:04Seems pretty good.
0:49:04 > 0:49:05No problem.
0:49:12 > 0:49:14Once Chris was happy with the fit...
0:49:20 > 0:49:23..Derek and I kept a close eye on how Pride was doing.
0:49:25 > 0:49:28The key thing, really, is for this camera to not interfere
0:49:28 > 0:49:30with any of her senses.
0:49:34 > 0:49:37Just a couple of minutes with the camera on her head
0:49:37 > 0:49:38- and she's forgotten all about it. - Yeah.
0:49:42 > 0:49:45It was encouraging to see how comfortable she looked,
0:49:45 > 0:49:48and how relaxed she was with other cheetahs in her enclosure.
0:49:51 > 0:49:53Oh, goodness me!
0:49:55 > 0:49:56She gets a bit of a face-lick.
0:49:58 > 0:49:59Wow.
0:50:00 > 0:50:02- Such an intimate moment. - Beautiful.
0:50:02 > 0:50:04Certainly is amazing.
0:50:05 > 0:50:08- Ah, that's lovely, look at that. - That really is.
0:50:09 > 0:50:11We had to be sure that Pride
0:50:11 > 0:50:14could reach top speed while wearing the camera.
0:50:14 > 0:50:17It wasn't long before she was off.
0:50:19 > 0:50:21- There she is.- Oh, whoa!
0:50:21 > 0:50:22Really fast, there we go.
0:50:22 > 0:50:24- Unbelievable. - That's an explosive speed.
0:50:24 > 0:50:25That thing is moving.
0:50:27 > 0:50:28Look at this.
0:50:30 > 0:50:31The footage was proof
0:50:31 > 0:50:35that our camera wouldn't put a cheetah off its stride.
0:50:37 > 0:50:40That's amazing, it really is excellent footage.
0:50:43 > 0:50:47We were now ready to join our three young orphan cheetahs
0:50:47 > 0:50:48as they learn to hunt.
0:50:51 > 0:50:56The next animal presented Chris with a very different set of problems.
0:50:58 > 0:51:01The wild baboons we wanted to film in South Africa
0:51:01 > 0:51:03were extremely scared of people.
0:51:05 > 0:51:08A camera test with them was out of the question.
0:51:08 > 0:51:10So once again, Chris needed a body double.
0:51:13 > 0:51:18We chose a group of hand-reared baboons in a sanctuary in Namibia.
0:51:18 > 0:51:19They weren't timid.
0:51:19 > 0:51:21In fact, quite the opposite.
0:51:23 > 0:51:25It is quite unusual working conditions.
0:51:25 > 0:51:27Ooh, ooh!
0:51:28 > 0:51:32Before making his prototype, Chris studied the way baboons move.
0:51:33 > 0:51:38In contrast to cheetahs, baboons move their heads all the time.
0:51:38 > 0:51:40For more stable shots,
0:51:40 > 0:51:43the camera would have to be worn around the neck.
0:51:44 > 0:51:47But this posed another problem
0:51:47 > 0:51:50due to the baboons' distinctive facial features.
0:51:52 > 0:51:54What I noticed is that their faces are very long.
0:51:55 > 0:51:58I'm quite concerned that the chin might get in the shot.
0:51:59 > 0:52:01But really, we've just got to try it now and see what we get.
0:52:03 > 0:52:07Testing was easier said than done.
0:52:07 > 0:52:08Are you going to wear a camera?
0:52:09 > 0:52:11The baboons might be used to people...
0:52:11 > 0:52:14Pff! OK.
0:52:14 > 0:52:16Um, hmm...
0:52:16 > 0:52:17..but they weren't used to wearing collars.
0:52:19 > 0:52:21It's to sort of make it into a bit of a game.
0:52:21 > 0:52:24Really don't want to annoy them or lose a finger.
0:52:26 > 0:52:27Oh, no, he's got it!
0:52:29 > 0:52:33Eventually, perseverance and patience paid off.
0:52:37 > 0:52:40But, as Chris had feared,
0:52:40 > 0:52:42the camera showed mostly chin.
0:52:45 > 0:52:48Over the next few days, Chris experimented,
0:52:48 > 0:52:52altering the position and angle of the camera to get the best results.
0:52:57 > 0:52:59And finally...
0:52:59 > 0:53:01..bingo!
0:53:03 > 0:53:07You can see, you've got the bottom of the chin just here,
0:53:07 > 0:53:09and the lens there.
0:53:09 > 0:53:11So height-wise, it's kind of
0:53:11 > 0:53:12just about there.
0:53:14 > 0:53:17The prototype camera could deliver great footage.
0:53:19 > 0:53:21But was it baboon-proof?
0:53:23 > 0:53:28An adult male baboon can weigh 40 kilos...
0:53:28 > 0:53:31and have canine teeth larger than a leopard's.
0:53:34 > 0:53:36But there's no way that will be strong enough,
0:53:36 > 0:53:38because a big wild male will just do that straight away.
0:53:40 > 0:53:44The last step was to add serious reinforcement -
0:53:44 > 0:53:47a stronger housing, and a thicker collar.
0:53:49 > 0:53:51Feels pretty much perfect.
0:53:51 > 0:53:55Now Chris's baboon cams had to work out in the wild.
0:53:59 > 0:54:01Once in South Africa,
0:54:01 > 0:54:05getting the cameras onto the baboons was fairly straightforward.
0:54:07 > 0:54:09There we go!
0:54:09 > 0:54:11Here, the biggest challenge...
0:54:12 > 0:54:14..was getting the cameras back.
0:54:19 > 0:54:22Each was set to drop off after two days filming.
0:54:22 > 0:54:26In such dense scrub, Leah's only chance of finding the camera
0:54:26 > 0:54:30was to track the baboon using the transmitter in its collar.
0:54:34 > 0:54:37But baboons have no respect for human boundaries.
0:54:37 > 0:54:40With its camera just about to drop off,
0:54:40 > 0:54:43our baboon went trespassing on a neighbouring farm.
0:54:45 > 0:54:47We saw the baboon with the collar on, with the camera,
0:54:47 > 0:54:49crossing the road.
0:54:49 > 0:54:51So she's just the other side of this fence now.
0:54:54 > 0:54:55Without permission to enter,
0:54:55 > 0:54:58Leah couldn't follow the baboon any further.
0:55:00 > 0:55:03It's 4.55, so her collar
0:55:03 > 0:55:06will be dropping off in five minutes.
0:55:06 > 0:55:09Bang on time, the camera dropped off.
0:55:13 > 0:55:16The battery in the tracking device would soon be dead.
0:55:18 > 0:55:22Finally, Leah got the go-ahead to enter the farm.
0:55:22 > 0:55:24It was now a race to find the camera
0:55:24 > 0:55:28before the battery and the daylight ran out.
0:55:29 > 0:55:31It's getting louder.
0:55:35 > 0:55:36I think it's that way.
0:55:39 > 0:55:42And just as night was closing in...
0:55:42 > 0:55:43Oh, there it is!
0:55:45 > 0:55:47Ah, yes.
0:55:47 > 0:55:48Ah.
0:55:50 > 0:55:51We've got the collar.
0:55:53 > 0:55:54I'm so happy.
0:56:00 > 0:56:01Next time...
0:56:01 > 0:56:04We dive into the Atlantic Ocean
0:56:04 > 0:56:08to reveal a secret gathering of giant devil rays.
0:56:10 > 0:56:13These are unbelievably privileged views.
0:56:13 > 0:56:15In the mountains of Turkey,
0:56:15 > 0:56:18we are with brown bears, where tensions are running high.
0:56:19 > 0:56:21- Ooh.- Oh, wow!
0:56:22 > 0:56:26And in France, we discover what happens
0:56:26 > 0:56:30when dogs come face to face with wolves.
