0:00:02 > 0:00:04Welcome to Natural Born Hunters,
0:00:04 > 0:00:06the show where three of the world's top predators
0:00:06 > 0:00:09go head to head in a race to eat.
0:00:13 > 0:00:17To be the fittest, the healthiest and at the top of their game,
0:00:17 > 0:00:19they all need food.
0:00:20 > 0:00:22Without it, they'll die.
0:00:22 > 0:00:25We compare how they hunt and why eating today
0:00:25 > 0:00:27really does matter.
0:00:28 > 0:00:32But even for top predators, mealtimes aren't always guaranteed.
0:00:33 > 0:00:36Success and failure hangs in the balance.
0:00:37 > 0:00:40Three will hunt, but only one will be crowned
0:00:40 > 0:00:42today's Natural Born Hunter.
0:00:43 > 0:00:45The question is - who are you backing?
0:00:51 > 0:00:53- I'm Steve.- And I'm Barney.
0:00:53 > 0:00:55And we'll be commentating on all the action.
0:00:57 > 0:01:01This week's Natural Born Hunters have one thing in common.
0:01:01 > 0:01:04When they hunt, their chief weapon is teamwork.
0:01:09 > 0:01:13This is our first contender, the wild dog team.
0:01:13 > 0:01:15They're also called hunting dogs
0:01:15 > 0:01:18cos hunting is what they're really good at.
0:01:18 > 0:01:20Just how good are they, Steve?
0:01:20 > 0:01:23Well, they're one of Africa's most successful hunters.
0:01:23 > 0:01:26- Come on, they can't be as good as lions.- They are.
0:01:27 > 0:01:29When they work as a team with up to 30 players,
0:01:29 > 0:01:32they can even take on the kings of the jungle
0:01:32 > 0:01:35and their hit rate on hunts is even higher.
0:01:35 > 0:01:37Impressive. OK, who's next?
0:01:39 > 0:01:41These guys are the chimpanzee team.
0:01:42 > 0:01:46They're one of our closest relatives and like us,
0:01:46 > 0:01:49they're very social and very smart.
0:01:49 > 0:01:51Yeah, I look a bit like one of them as well.
0:01:51 > 0:01:52How do they work as a team?
0:01:52 > 0:01:55They know that working together in groups of ten or more
0:01:55 > 0:01:57helps them to hunt better.
0:01:57 > 0:01:59What do they hunt? You can't hunt bananas.
0:01:59 > 0:02:03They don't just eat bananas. They also eat bugs,
0:02:03 > 0:02:05- grubs, lizards...- Gross.
0:02:05 > 0:02:08..and something even worse than that.
0:02:08 > 0:02:10- What?- I'll tell you later.
0:02:12 > 0:02:15- And here are our final team. - You did that on porpoise.
0:02:15 > 0:02:18I know, I know. You love dolphins, don't you, Barn?
0:02:18 > 0:02:20- I do.- They live in complex societies
0:02:20 > 0:02:22and there can be as many as 1,000 in a team.
0:02:22 > 0:02:251,000 - that is a lot of team-mates to keep track of.
0:02:25 > 0:02:29It is. So it's just as well these guys are really smart.
0:02:29 > 0:02:33A dolphin's brain is one of the largest in the animal kingdom.
0:02:33 > 0:02:36- Is it as big as mine? - Oh, no. No way.
0:02:36 > 0:02:38- Ha! It is, isn't it? - Yeah, probably.
0:02:38 > 0:02:41In underwater teamwork, few animals can compete
0:02:41 > 0:02:45with dolphins, and they've invented some amazing hunting strategies.
0:02:45 > 0:02:48- Take a look at this.- Wow!
0:02:48 > 0:02:52By swimming in formation, they're creating mini tidal waves
0:02:52 > 0:02:54that drive shoals of fish out of the water
0:02:54 > 0:02:57- with tasty pickings for all. - I've never seen fishing
0:02:57 > 0:03:00done like that before. That is what I call teamwork.
0:03:04 > 0:03:09OK, that's our line-up. Wild dogs, chimpanzees and dolphins.
0:03:09 > 0:03:13Three teams, each with amazing hunting skills and team tactics.
0:03:13 > 0:03:16But which team will win the premiership and get to eat today?
0:03:16 > 0:03:18What do you reckon, Barn?
0:03:18 > 0:03:20Well, it seems quite obvious,
0:03:20 > 0:03:22cos dolphins have got 1,000 team-maters.
0:03:22 > 0:03:25Yeah, but there's a lot of other factors coming into play here.
0:03:25 > 0:03:27Not just numbers.
0:03:27 > 0:03:29The teams have to communicate, work together,
0:03:29 > 0:03:32and even the best can be brought down by circumstances
0:03:32 > 0:03:34beyond their control.
0:03:34 > 0:03:36- Like what?- Bad weather can stop play.
0:03:36 > 0:03:39Rival teams can put in an appearance.
0:03:39 > 0:03:42OK, well, now I don't know who to support.
0:03:42 > 0:03:43To help everyone at home decide,
0:03:43 > 0:03:47we're going to get to know each of our contenders a bit better
0:03:47 > 0:03:50by recreating a day in their lives as they prepare to hunt.
0:03:50 > 0:03:52This fuel gauge will help us keep track
0:03:52 > 0:03:54of how much food each team eats.
0:03:54 > 0:03:57Whichever fills up first is the winner.
0:03:57 > 0:03:58It sounds like a plan.
0:04:03 > 0:04:06In the thick forests of Central Africa,
0:04:06 > 0:04:09the day is just beginning for our chimpanzee team.
0:04:10 > 0:04:13This is a very important day for this teenage male chimp,
0:04:13 > 0:04:16as he's going to go on his first hunt
0:04:16 > 0:04:19and he wants to make a good impression on the adult males.
0:04:19 > 0:04:21He must be feeling a bit nervous, then.
0:04:21 > 0:04:24It's a bit like your first big day at school, isn't it?
0:04:26 > 0:04:28- Hang on.- What's he doing?
0:04:28 > 0:04:30He's just grooming another member of the team.
0:04:30 > 0:04:33By giving each other a good clean,
0:04:33 > 0:04:36getting rid of nits or any other nasty parasites,
0:04:36 > 0:04:38they bond and make friends.
0:04:38 > 0:04:40It's important to get on with each other
0:04:40 > 0:04:42if you want to be part of a winning team.
0:04:42 > 0:04:46Yes, that's right. If you all care for each other and work together,
0:04:46 > 0:04:48you're more likely to hunt successfully.
0:04:48 > 0:04:52What else do they hunt, apart from bugs, grubs and gross lizards?
0:04:53 > 0:04:56Believe it or not, they'll also hunt monkeys.
0:04:56 > 0:04:59- Hang on. Apes eat monkeys?- Yeah.
0:04:59 > 0:05:01It's really hard to find protein in the jungle,
0:05:01 > 0:05:05and like us, chimps need a lot to grow and survive.
0:05:05 > 0:05:08Well, the fuel gauge is looking pretty low at the moment.
0:05:08 > 0:05:10To fill it up, our teenager and the team
0:05:10 > 0:05:14could really do with finding a decent meal of protein.
0:05:14 > 0:05:16A good-sized monkey is just what they need
0:05:16 > 0:05:19to feed these hungry mouths.
0:05:27 > 0:05:31Now it's time to meet our underwater synchronised swimming team.
0:05:31 > 0:05:36Say good morning to our ten-strong pod of bottlenose dolphins
0:05:36 > 0:05:38living off the coast of Florida.
0:05:38 > 0:05:41They're all good mates and some of them are related.
0:05:41 > 0:05:43Check out the mums and the toddlers.
0:05:43 > 0:05:46This young girl is just five months old,
0:05:46 > 0:05:47and she's staying close to Mum,
0:05:47 > 0:05:49learning all the time about her world.
0:05:49 > 0:05:53She's still suckling, so relies on Mum's milk to feed her.
0:05:53 > 0:05:56So, she doesn't have to hunt, then?
0:05:56 > 0:05:58Sun, sea and lots of swimming.
0:05:58 > 0:06:01Life must be one long holiday for these youngsters.
0:06:01 > 0:06:04Seems like it, but look at this. The sea has dangers.
0:06:07 > 0:06:10Speedboats, fishing nets, even sharks...
0:06:11 > 0:06:14One in five won't make it to their first birthday.
0:06:14 > 0:06:17- So, our youngster's got a long way to go.- She has.
0:06:17 > 0:06:19But she isn't completely vulnerable.
0:06:19 > 0:06:21Her mum and the other adults
0:06:21 > 0:06:23are constantly on the lookout for predators.
0:06:25 > 0:06:27This pod has been together for years
0:06:27 > 0:06:29and work really well as a team,
0:06:29 > 0:06:31sharing all that they catch.
0:06:31 > 0:06:33- Check our their fuel gauge. - It's nearly empty.
0:06:33 > 0:06:37They haven't eaten a decent meal for a few days,
0:06:37 > 0:06:39so it's critical they find a big shoal
0:06:39 > 0:06:41of 100 or more fish today.
0:06:41 > 0:06:43Basically, if the pod get to eat,
0:06:43 > 0:06:46then so does Mum and our youngster.
0:06:46 > 0:06:48Cool. Who's the final contender, then?
0:06:51 > 0:06:53Right, well, this is the Okavango Delta in Africa.
0:06:54 > 0:06:56Hey, doggies.
0:06:56 > 0:06:59They may look a bit like your friendly local mongrels
0:06:59 > 0:07:03but this is a wild and highly-tuned hunting team
0:07:03 > 0:07:06who can bring down animals six times bigger than them.
0:07:06 > 0:07:09- And they've got puppies. - Cute, aren't they?
0:07:09 > 0:07:11This one here is the youngest in the pack.
0:07:11 > 0:07:14He's also the smallest, which means he's the most likely
0:07:14 > 0:07:18- to get attacked by predators. - Who would hurt a cute little puppy?
0:07:18 > 0:07:20Lions and hyenas, for a start.
0:07:20 > 0:07:23To them, he'd make a really good snack.
0:07:23 > 0:07:25You'd better watch out, little fellow.
0:07:25 > 0:07:26Was that his dad?
0:07:26 > 0:07:30Yes. And he knows how important it is to bring back some food
0:07:30 > 0:07:33today, as you can tell from the fuel gauge, his pup
0:07:33 > 0:07:37and the rest of the pack haven't eaten for nearly two days.
0:07:37 > 0:07:40They must be starving. A lot of pressure on Dad here.
0:07:40 > 0:07:41There is. But remember,
0:07:41 > 0:07:43they work as a team.
0:07:43 > 0:07:46It's the responsibility of the whole pack to feed
0:07:46 > 0:07:49and look after the pups. If they're going to win,
0:07:49 > 0:07:52they need to catch an antelope big enough to feed the whole team.
0:07:55 > 0:07:58They should win just cos they've got cute puppies.
0:08:03 > 0:08:05While they get into their stride,
0:08:05 > 0:08:08let's catch up with our other African team.
0:08:08 > 0:08:10I love these guys, the chimpanzees.
0:08:10 > 0:08:12Oh, hello, what's our teenager up to?
0:08:13 > 0:08:15Good, he's poking stuff with a stick.
0:08:17 > 0:08:18This is actually pretty clever.
0:08:18 > 0:08:21He's fishing for termites.
0:08:22 > 0:08:26He's stripped the leaves off a twig and he's poking it into the hole.
0:08:27 > 0:08:32Look at this. A tasty meal of yummy termites on the end.
0:08:32 > 0:08:34That's the most effective spoon ever.
0:08:34 > 0:08:38These insects will give their muscles a quick boost of energy
0:08:38 > 0:08:39for the hunt ahead.
0:08:42 > 0:08:44Yeah, look, the fuel gauge is going up.
0:08:45 > 0:08:47CHIMPS JABBER What's that one doing?
0:08:47 > 0:08:50Well, that's one of the adult males.
0:08:50 > 0:08:53He's drumming on the tree to call the team together.
0:08:53 > 0:08:57Snack time's done, the hunt is about to begin.
0:09:02 > 0:09:05While they get sorted out, let's look at the dolphins.
0:09:11 > 0:09:14Look, there's our young female, look at her go.
0:09:14 > 0:09:16The pod have started their hunt for fish.
0:09:16 > 0:09:18This gives us a chance to have a look
0:09:18 > 0:09:21at what makes them such awesome predators.
0:09:22 > 0:09:25Their large tail is almost all muscle.
0:09:25 > 0:09:27It powers them through the water
0:09:27 > 0:09:30- at speeds of up to 20 miles an hour. - Like torpedoes.
0:09:30 > 0:09:32They have great eyesight too.
0:09:32 > 0:09:35Their eyes are on the side of their heads, which means
0:09:35 > 0:09:38they see predators, such as sharks approaching from behind them.
0:09:38 > 0:09:41- Do you mind if we leave the sharks out of it?- OK, Barney.
0:09:41 > 0:09:45Thanks to an extremely flexible eye lens
0:09:45 > 0:09:48they have superb vision, both above water and below it.
0:09:48 > 0:09:51It's like having built-in swimming goggles.
0:09:51 > 0:09:52I could do with a pair of those.
0:09:57 > 0:09:59All of our teams have started to hunt.
0:09:59 > 0:10:01The chimp team need to catch a monkey
0:10:01 > 0:10:03to provide protein for the entire group.
0:10:03 > 0:10:06If our teenage chimp wants to be a winner,
0:10:06 > 0:10:08he has to help the troupe catch dinner.
0:10:09 > 0:10:12Our hunting dog dad and the wild dog pack
0:10:12 > 0:10:16have got to catch an antelope large enough to feed
0:10:16 > 0:10:18all those hungry mouths, including our young pup.
0:10:20 > 0:10:23And the dolphins have to find a shoal of over 100 fish
0:10:23 > 0:10:24to feed the pod.
0:10:24 > 0:10:26Which means our young girl
0:10:26 > 0:10:28will also get to feed.
0:10:28 > 0:10:30So, keep an eye on those fuel gauges,
0:10:30 > 0:10:32because the first to fill up is the winner.
0:10:36 > 0:10:38OK, so, time to check in with our dogs.
0:10:41 > 0:10:43When we last saw them, they'd just started.
0:10:43 > 0:10:47It's an hour later and they're still searching for possible prey.
0:10:48 > 0:10:52These dogs have some energy. They've been running at that speed for ages.
0:10:52 > 0:10:56It's unreal. There's no such thing as an easy meal for these guys,
0:10:56 > 0:10:58as their prey is constantly on the move.
0:10:58 > 0:11:01They often have to travel several miles
0:11:01 > 0:11:03before they even get a sighting of a meal.
0:11:03 > 0:11:06They can keep up this pace all day long,
0:11:06 > 0:11:08as they've got unbelievable stamina.
0:11:08 > 0:11:11Their long legs and slight bodies help them cover
0:11:11 > 0:11:13enormous amounts of ground.
0:11:13 > 0:11:16I keep thinking of that hungry pup back at the den.
0:11:16 > 0:11:18I think Dad is too.
0:11:18 > 0:11:21Look at the pack's fuel gauge. Their energy levels are really low.
0:11:21 > 0:11:24Hunting like this really burns up the calories.
0:11:24 > 0:11:27For now, they just have to keep on the move looking for food.
0:11:30 > 0:11:32Now, our chimps have also been out for about an hour
0:11:32 > 0:11:35looking up in the treetops for a decent meal.
0:11:35 > 0:11:37They also need vital fuel
0:11:37 > 0:11:39but those pre-hunt snacks help keep them going.
0:11:41 > 0:11:44- Is our teenager with them?- Erm... Yes! There he is.
0:11:44 > 0:11:46Oh, hang on.
0:11:46 > 0:11:50They're making him sit and watch how they do it before he has a go.
0:11:50 > 0:11:52Why? I thought he was part of the team.
0:11:52 > 0:11:55As they haven't had a decent meal for weeks,
0:11:55 > 0:11:57they can't afford to get it wrong.
0:11:59 > 0:12:00OK. What are they hunting?
0:12:00 > 0:12:05Well...today, they're after the red colobus monkey.
0:12:06 > 0:12:09Rich in protein, but it lives way up in the treetops.
0:12:10 > 0:12:13I've noticed the monkeys have legs. Can't they just run away?
0:12:13 > 0:12:18They can, but our chimpanzee team use very clever hunting techniques.
0:12:18 > 0:12:22So, one chimp's climbing up after the monkey.
0:12:22 > 0:12:26- He's been spotted.- He has. That's what he wants.
0:12:26 > 0:12:29Now, two other chimps move up on the other sides.
0:12:29 > 0:12:32They're the blockers to make sure the monkey can't get away.
0:12:32 > 0:12:35- Nice tactics.- We can see it even better on the hunter radar.
0:12:37 > 0:12:39Yeah, there's the monkey.
0:12:44 > 0:12:47Here's the clever bit. This chimp is the catcher.
0:12:47 > 0:12:51He's climbed up ahead of the monkey and is waiting to ambush him.
0:12:53 > 0:12:56They've really worked this out, haven't they?
0:12:56 > 0:12:58Yes. It's a precision business.
0:12:58 > 0:13:00This is what our teenager has to learn
0:13:00 > 0:13:02for when he gets a go.
0:13:04 > 0:13:05The lead chimp's moving in.
0:13:05 > 0:13:08It's all systems go for the chimp team.
0:13:08 > 0:13:10They're driving the monkey towards the catcher.
0:13:12 > 0:13:14What's happening, Steve?
0:13:14 > 0:13:16Let's switch to the hunter radar to find out.
0:13:19 > 0:13:20So, there's a gap in the trap.
0:13:20 > 0:13:23The monkey's seen it and he's heading for it.
0:13:25 > 0:13:27Look, the monkey's got away.
0:13:29 > 0:13:31All that hard work and no meal.
0:13:31 > 0:13:33They'll have to try again later.
0:13:36 > 0:13:39So, what about our young dolphin?
0:13:39 > 0:13:42Like the other two teams, the pod have been on the move
0:13:42 > 0:13:43for about an hour now.
0:13:43 > 0:13:46It looks as though they've found some tasty titbits.
0:13:46 > 0:13:49The fish are hiding in the sand. Not going to find them now.
0:13:49 > 0:13:52Dolphins have another way of seeing the world
0:13:52 > 0:13:55that helps them catch fish. They have a special sense
0:13:55 > 0:13:58called echo location, which allows them to see
0:13:58 > 0:14:00right through the sand.
0:14:03 > 0:14:05Dolphins send out very high-frequency sound waves.
0:14:05 > 0:14:08When the waves hit an object like a fish, they bounce back
0:14:08 > 0:14:10and a dolphin is able to hear this sound
0:14:10 > 0:14:12and work out where the fish are.
0:14:12 > 0:14:15It means they can still catch fish in really murky water
0:14:15 > 0:14:18or right down in the sand, like our mum's doing here.
0:14:23 > 0:14:25Look at the fuel gauge. It's going up a bit,
0:14:25 > 0:14:26but it's still got a way to go.
0:14:26 > 0:14:29With so many mouths to feed, what they need to find
0:14:29 > 0:14:32is a big school of fish, so they'll have to keep looking.
0:14:40 > 0:14:42In Africa, the dogs are still on the run.
0:14:44 > 0:14:47They've stopped. Bet they've run out of energy, haven't they?
0:14:47 > 0:14:48I don't think so.
0:14:48 > 0:14:50Look.
0:14:50 > 0:14:52They've spotted their favourite prey.
0:14:52 > 0:14:53A herd of impala.
0:14:53 > 0:14:58Where have the dogs gone? I can hardly see them.
0:14:59 > 0:15:02Their darkly-coloured coats make them difficult to see.
0:15:02 > 0:15:04And they've gone deadly quiet.
0:15:04 > 0:15:07Working as a team is important,
0:15:07 > 0:15:09because the impala have very sensitive hearing.
0:15:09 > 0:15:13If any of the dogs bark or make a wrong move, the impala would run.
0:15:15 > 0:15:17But if you have to keep quiet,
0:15:17 > 0:15:19how do they communicate - walkie-talkies?
0:15:19 > 0:15:22Those ears act like signalling devices.
0:15:22 > 0:15:25They tilt them to communicate their positions.
0:15:29 > 0:15:31That is the signal to go.
0:15:31 > 0:15:35The pack splits, some head left, some right.
0:15:35 > 0:15:37If we switch to the hunter radar,
0:15:37 > 0:15:39we see the dogs spacing themselves out
0:15:39 > 0:15:41to form a cordon around the antelope.
0:15:41 > 0:15:44Dad's taken the lead and has moved in right behind the impala.
0:15:48 > 0:15:49Everyone's in place.
0:15:49 > 0:15:51The trap is set.
0:16:00 > 0:16:02Dad's off. Three of the pack join him to separate
0:16:02 > 0:16:04one impala from the herd.
0:16:05 > 0:16:07They're driving the lone impala forward
0:16:07 > 0:16:10and the hidden flankers move in from the side.
0:16:13 > 0:16:15Look at them go!
0:16:17 > 0:16:20Nice, fast and they've got one, Steve, brilliant teamwork.
0:16:22 > 0:16:24Now it's time to enjoy the feast.
0:16:24 > 0:16:27- They even eat the bones!- Yep.
0:16:27 > 0:16:29They've got one of the most powerful bites.
0:16:29 > 0:16:33They can crunch up every morsel. Nothing goes to waste.
0:16:33 > 0:16:36- They don't hang around. - They want to eat quickly.
0:16:36 > 0:16:39They don't want to attract any attention.
0:16:39 > 0:16:40Attention from what?
0:16:40 > 0:16:42Attention...
0:16:42 > 0:16:44from these.
0:16:44 > 0:16:45Hyena.
0:16:45 > 0:16:48It's not going to take on all those dogs.
0:16:52 > 0:16:54He will if he's really hungry.
0:16:58 > 0:17:01Using teamwork, they've seen him off.
0:17:01 > 0:17:03The pack have got no time to lose.
0:17:03 > 0:17:06They've got to bolt as much food as they can
0:17:06 > 0:17:08before the hyena returns with mates.
0:17:09 > 0:17:11Oh, no, the dad's been hurt.
0:17:11 > 0:17:13That doesn't look good.
0:17:13 > 0:17:15He must have been bitten by the hyena.
0:17:16 > 0:17:18Look at the fuel gauge.
0:17:18 > 0:17:22Cos the hyena stole some food there won't be enough for all the pups.
0:17:24 > 0:17:27Our dad's leading the pack back to the den
0:17:27 > 0:17:29to give the pups as much food as he can.
0:17:36 > 0:17:39So, time for a look at the state of play.
0:17:39 > 0:17:41The chimpanzee team have been unsuccessful
0:17:41 > 0:17:44in their first hunt, and our teenager
0:17:44 > 0:17:47is still waiting for his big chance to prove himself.
0:17:52 > 0:17:54Our pod of dolphins fuelled by a fish snack
0:17:54 > 0:17:57are now on the hunt for a large shoal of fish.
0:17:58 > 0:18:01Finally, the wild dogs made a successful kill
0:18:01 > 0:18:04and managed to get a quick meal before losing out to a hyena.
0:18:04 > 0:18:07Our dad is limping home
0:18:07 > 0:18:09after the attack to feed the hungry pups.
0:18:15 > 0:18:17CHIMPS JABBER
0:18:17 > 0:18:20Our chimpanzee team are on the hunt again
0:18:20 > 0:18:23and have spotted another group of monkeys.
0:18:23 > 0:18:24They're moving in
0:18:24 > 0:18:27using the team tactics we saw earlier.
0:18:27 > 0:18:30Hey, look, our teenager's been allowed to join in.
0:18:30 > 0:18:33- I hope he doesn't blow it. - Why are they making so much noise?
0:18:33 > 0:18:35They're really starving
0:18:35 > 0:18:37and excited at the thought of eating.
0:18:37 > 0:18:40It happens to me all the time. For the chimps,
0:18:40 > 0:18:43it's their way of getting hyped up for the hunt.
0:18:43 > 0:18:44Oh, no, here comes trouble.
0:18:44 > 0:18:48- Really?- Nah, it's just more chimps. Maybe they've come to help.
0:18:48 > 0:18:51No, the noise has attracted a rival team.
0:18:51 > 0:18:54This is a really serious situation.
0:18:56 > 0:18:59- Are they going to have a bit of a scrap?- If they get a chance,
0:18:59 > 0:19:00they'll kill each other.
0:19:07 > 0:19:10No way, they've singled out our teenager.
0:19:10 > 0:19:13Probably because he's the least experienced. He's in trouble.
0:19:15 > 0:19:17Go on, fella, run.
0:19:17 > 0:19:22He's managed to break away, but it looks like he's hurt from the fight.
0:19:22 > 0:19:25The troupe's going to have to regroup and rest
0:19:25 > 0:19:27if they're to try hunting again today.
0:19:32 > 0:19:33It's the middle of the day
0:19:33 > 0:19:36and the dolphin team have been hunting for over five hours.
0:19:38 > 0:19:41- Oh, what about the surfing? - Surf's up, dudes.
0:19:41 > 0:19:44They're on their way to one of their favourite hunting grounds,
0:19:44 > 0:19:48and riding these waves means they can save some valuable energy.
0:19:48 > 0:19:51I can't say I blame them. Those waves look cool.
0:19:51 > 0:19:52DOLPHINS SQUEAK
0:19:52 > 0:19:55What are those noises? It sounds like talking.
0:19:55 > 0:19:57Each dolphin has a unique whistle.
0:19:57 > 0:20:00This allows them to keep track of each other
0:20:00 > 0:20:03and keep their tightly-knit group together.
0:20:03 > 0:20:05This will help them to work as a team
0:20:05 > 0:20:06and co-ordinate their attack
0:20:06 > 0:20:09once they find the big shoal of fish they're after.
0:20:09 > 0:20:11For now, they just have to keep looking.
0:20:17 > 0:20:19Cool, the wild dogs have made it back.
0:20:19 > 0:20:22THEY BARK
0:20:30 > 0:20:31Oh, no, Dad's been sick.
0:20:31 > 0:20:34- No!- I know it looks pretty grim, Barney,
0:20:34 > 0:20:38but, actually, what's happening is he's feeding the pups.
0:20:38 > 0:20:41What Dad'll do is regurgitate most of the meat he's eaten,
0:20:41 > 0:20:43and I know it seems pretty unpleasant,
0:20:43 > 0:20:47but for these guys, it's the best way to bring home a meal.
0:20:47 > 0:20:49Bring up a meal. Nice.
0:20:49 > 0:20:50With 12 puppies to feed,
0:20:50 > 0:20:53there's just not enough food to go round
0:20:53 > 0:20:56and it looks as though our youngster isn't getting his fair share.
0:20:56 > 0:20:59Has the pack got to go back out again?
0:20:59 > 0:21:02They will, but right now is the hottest part of the day,
0:21:02 > 0:21:05and there's no point trying. They'll overheat and waste energy.
0:21:05 > 0:21:09- So, nothing to do but sit it out. - Yes. It's not just fun in the sun.
0:21:09 > 0:21:13Look. Dad's getting his wound looked after by the rest of the pack.
0:21:13 > 0:21:16They really do look after each other, don't they?
0:21:18 > 0:21:21The chimpanzee team are back out and they've spotted another troupe
0:21:21 > 0:21:23of red colobus monkeys.
0:21:23 > 0:21:25This could be our teenager's big moment.
0:21:25 > 0:21:26How's he doing?
0:21:26 > 0:21:30It looks like he's recovered enough to join in the hunt.
0:21:35 > 0:21:39And...here we go. That's the chaser chimp getting the monkey to move.
0:21:39 > 0:21:43I can see the blockers moving into position either side of the monkey.
0:21:43 > 0:21:46He can't escape, but the monkey's still going
0:21:46 > 0:21:49- faster than the chimps.- That's where the catcher comes into play.
0:21:49 > 0:21:54Look, that role's been taken on by our teenager.
0:21:58 > 0:22:02Come on, fellow, this is your big chance to impress your team-mates.
0:22:02 > 0:22:05Everyone's getting excited. They're getting into position.
0:22:05 > 0:22:08The colobus is making a break for freedom!
0:22:09 > 0:22:12- He's caught it! Yes, he's got it! No!- Oh!
0:22:12 > 0:22:14He's dropped it. Whoa!
0:22:16 > 0:22:19Aw, he must be gutted. But he's young, though.
0:22:19 > 0:22:22He's learning. Surely he'll get another chance, won't he?
0:22:22 > 0:22:25He'll have plenty more chances, but for today, it's all over
0:22:25 > 0:22:28for the chimps. The light in the jungle's fading.
0:22:28 > 0:22:31It's too dangerous to continue hunting.
0:22:31 > 0:22:34Despite some fantastic teamwork, they're going to be returning
0:22:34 > 0:22:37to the group with nothing to show for their effort.
0:22:37 > 0:22:40They're officially out of the game.
0:22:41 > 0:22:44Aw, life's tough for these guys.
0:22:44 > 0:22:47It is, but they'll be out again hunting tomorrow.
0:22:49 > 0:22:51So, that's one down, two to go.
0:22:51 > 0:22:54For the dolphins and for the wild dogs,
0:22:54 > 0:22:57the battle to eat continues.
0:22:57 > 0:22:58Time for them to go head to head.
0:23:02 > 0:23:03It's now early evening.
0:23:03 > 0:23:06The dolphins have been on the move for eight hours.
0:23:08 > 0:23:11They've come to one of their favourite fishing grounds,
0:23:11 > 0:23:14- this lagoon.- It looks a bit murky. - That's no problem for the dolphins.
0:23:14 > 0:23:17They can see through that with their special
0:23:17 > 0:23:21- echo-location.- Oh, yeah, I remember. They sound excited.- They are.
0:23:21 > 0:23:24Those whistles and clicks are them talking to each other
0:23:24 > 0:23:26as they plan their attack.
0:23:29 > 0:23:31In Africa, the temperature's dropped,
0:23:31 > 0:23:35and the wild dogs have recovered enough to head out again.
0:23:35 > 0:23:38They've been out hunting for over an hour.
0:23:38 > 0:23:39Look, there's Dad.
0:23:39 > 0:23:42Yup, even though he's hurt,
0:23:42 > 0:23:44he's back out leading the pack.
0:23:44 > 0:23:46They just don't stop, do they?
0:23:46 > 0:23:48No, giving up is just not an option.
0:23:48 > 0:23:51The pups are still desperately hungry,
0:23:51 > 0:23:55and our little one needs to get his fair share if he's going to survive.
0:23:57 > 0:24:01Our dolphin mum's also desperate to get a good catch,
0:24:01 > 0:24:04so she can produce enough milk to feed her young one.
0:24:04 > 0:24:07The dolphins have entered one of the deep channels.
0:24:07 > 0:24:10On either side of the channels are shallower ones.
0:24:10 > 0:24:13It's here where big shoals of fish are.
0:24:14 > 0:24:16Just listen to all that talking going on.
0:24:16 > 0:24:19- DOLPHINS SQUEAK - They just have to get closer.
0:24:19 > 0:24:22Then they can launch their co-ordinated attack.
0:24:23 > 0:24:26Meanwhile, the dogs have spotted another herd of impala.
0:24:26 > 0:24:29They're using all the team tactics we saw earlier.
0:24:29 > 0:24:34They've gone quiet and are signalling using their ears.
0:24:35 > 0:24:39One of the dogs breaks off to stop the impala escaping to the left.
0:24:39 > 0:24:41Then the other one. They can't escape to the right.
0:24:45 > 0:24:49Back with our pod, Mum has split away from the rest of the group.
0:24:49 > 0:24:53She's dived down and is kicking up the mud, swimming in a circle.
0:24:53 > 0:24:56That's clever - she's circling the fish.
0:24:56 > 0:24:57Exactly. She can't see the fish.
0:24:57 > 0:25:00So, she's using her echo-location skills to find them.
0:25:00 > 0:25:03The team join her and they're all talking to each other
0:25:03 > 0:25:05getting into position.
0:25:14 > 0:25:17Back in Africa, Dad's driving the impala
0:25:17 > 0:25:20towards the hidden flankers. It's game on.
0:25:22 > 0:25:25Oh! How close was that?
0:25:25 > 0:25:28Dad's still going, though, isn't he?
0:25:28 > 0:25:29It's one on one now.
0:25:29 > 0:25:32The dog has stamina, the impala speed.
0:25:34 > 0:25:36The dolphins are all in position.
0:25:36 > 0:25:38That circle of mud that's been stirred up
0:25:38 > 0:25:41by the lead dolphins has confused the fish.
0:25:41 > 0:25:44They think they've been trapped, and they're panicking.
0:25:47 > 0:25:50They're leaping out the water! Straight into the dolphins' mouths!
0:25:56 > 0:25:58That is incredible.
0:25:58 > 0:26:00And look, fuel gauge is filling up.
0:26:00 > 0:26:03Yes, talk about food coming straight to you.
0:26:03 > 0:26:04Look at that! Good catch.
0:26:09 > 0:26:10Our dad's still on the chase.
0:26:13 > 0:26:16He's tired, he's hurt and he's not in great shape,
0:26:16 > 0:26:17but he's not giving up.
0:26:20 > 0:26:22Now he's in trouble. He's gone in the water.
0:26:22 > 0:26:24Oh, no.
0:26:24 > 0:26:26Although the impala can't swim very well,
0:26:26 > 0:26:29the wild dogs will not follow it into there.
0:26:29 > 0:26:32- They just wait for it?- No. They're away from their pups.
0:26:32 > 0:26:35They need to travel back before it's dark to protect them.
0:26:36 > 0:26:38No dinner for our hungry little puppy, then?
0:26:38 > 0:26:42Well...not today. The pack will be out again at first light tomorrow.
0:26:42 > 0:26:45You can rest assured they'll do all they can to feed them.
0:26:45 > 0:26:46I hope so.
0:26:47 > 0:26:49Hey, look at the dolphins!
0:26:49 > 0:26:52I can't believe how many fish they're catching.
0:26:52 > 0:26:53Look at the fuel gauge.
0:26:55 > 0:26:57Looks like all the pod are feeding well,
0:26:57 > 0:26:59including our mum.
0:26:59 > 0:27:02And she's feeding her young one.
0:27:02 > 0:27:04I think we'd better announce the winner, Steve.
0:27:06 > 0:27:09Today's champions are the dolphin team.
0:27:10 > 0:27:14- They've done it! Didn't they do well? - Great performance and co-ordination.
0:27:14 > 0:27:17Legendary teamwork. What amazing animals!
0:27:17 > 0:27:20Commiserations to our runners-up, the chimps and the wild dogs.
0:27:22 > 0:27:25There's no doubt the chimps are great hunters,
0:27:25 > 0:27:28but the colobus monkeys proved just too fast today.
0:27:31 > 0:27:34The wild dogs' team-working spirit is incredible
0:27:34 > 0:27:38and they just missed out bringing back a whole impala to the pups.
0:27:39 > 0:27:42So, with an awesome display of team hunting,
0:27:42 > 0:27:44the dolphins are our Natural Born Hunters!
0:27:45 > 0:27:49Join us next time, when we'll be seeking three more contenders
0:27:49 > 0:27:52to earn the title of Natural Born Hunter. See you then. Bye.
