0:00:02 > 0:00:04Welcome to Natural Born Hunters,
0:00:04 > 0:00:08where three of the world's top predators go head-to-head
0:00:08 > 0:00:10in a race to eat.
0:00:13 > 0:00:17To be the fittest, 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 > 0:00:24We compare how they hunt
0:00:24 > 0:00:26and why eating today really does matter.
0:00:28 > 0:00:30But even for top predators,
0:00:30 > 0:00:32meal times aren't always guaranteed.
0:00:33 > 0:00:36Success and failure hangs in the balance.
0:00:37 > 0:00:38Three will hunt,
0:00:38 > 0:00:42but only one will be crowned today's Natural Born Hunter.
0:00:42 > 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 > 0:00:56We'll take you through today's amazing line-up of animal assassins
0:00:56 > 0:00:59as they go head-to-head to feed first.
0:00:59 > 0:01:03It'll be fast and furious, but we'll be there every step of the way.
0:01:03 > 0:01:06- Who are we looking at today, Steve? - Well, Barney,
0:01:06 > 0:01:10when you think predator, you think power.
0:01:10 > 0:01:14And these three contenders all pack a powerful punch.
0:01:14 > 0:01:17Their powerful muscles are critical for hunting.
0:01:17 > 0:01:21But before they can eat, they have to find and follow their prey.
0:01:21 > 0:01:25- Which isn't always easy.- I can't wait to see these guys in action.
0:01:25 > 0:01:29Our three hunters all have very different ways of getting a meal.
0:01:29 > 0:01:32But all of them using their enormous power.
0:01:35 > 0:01:38Here's our first contender.
0:01:38 > 0:01:42- I'd recognise that laugh anywhere. Those are hyenas.- Yes.
0:01:42 > 0:01:45Contender number one is the spotted hyena.
0:01:45 > 0:01:49Look at those teeth! I wouldn't want to meet those guys on a dark night.
0:01:49 > 0:01:51They have phenomenally powerful jaws
0:01:51 > 0:01:54and one of the strongest bites in the world.
0:01:54 > 0:01:56With a force of half a ton,
0:01:56 > 0:01:59they can crush bones like us munching popcorn.
0:01:59 > 0:02:03That is sheer power. They don't actually eat the bone, do they?
0:02:03 > 0:02:07They eat the bone, the hair, even hooves, horns and teeth!
0:02:07 > 0:02:09They can pretty much digest the lot.
0:02:09 > 0:02:14Not just a scavenger, but a predator you wouldn't want to fall out with.
0:02:14 > 0:02:16Nice - food with hair on it (!) What's next?
0:02:16 > 0:02:20OK, contender number two is the powerhouse of the oceans,
0:02:20 > 0:02:22the Great White Shark.
0:02:22 > 0:02:25I know that these guys are serious hunters.
0:02:25 > 0:02:27With rows of razor-sharp teeth,
0:02:27 > 0:02:32these super-heavyweight fish can deliver a bite of two tons.
0:02:32 > 0:02:36- Sends shivers down my spine! - They're powerful swimmers, too.
0:02:36 > 0:02:39With bursts of speed of 25 miles an hour,
0:02:39 > 0:02:42they can ambush their prey, catching them completely unawares.
0:02:42 > 0:02:45- That's one big powerful fish. - Too right. Now,
0:02:45 > 0:02:48- our final contender.- Wow, a bird.
0:02:48 > 0:02:51Not just any bird, Barn. This is the osprey,
0:02:51 > 0:02:55the bird that's mastered the art of the air and the water.
0:02:55 > 0:02:59How can they be considered powerful after we've just seen a shark?
0:02:59 > 0:03:02It may weigh the same as a bag of sugar,
0:03:02 > 0:03:06but believe me, it can still pack one heck of a punch.
0:03:06 > 0:03:10They're the ultimate fishermen. Their power lies in their muscles.
0:03:10 > 0:03:15Most birds can fly. I'm not sure about this one's credentials.
0:03:15 > 0:03:18After smashing into the water at up to 45 miles an hour,
0:03:18 > 0:03:20they have to take off
0:03:20 > 0:03:23carrying a fish that could weigh as much as they do.
0:03:23 > 0:03:26- If they don't, they could drown. - OK, I trust you.
0:03:28 > 0:03:31That's our line-up. The spotted hyena. The great white shark
0:03:31 > 0:03:33and the osprey.
0:03:33 > 0:03:35But can you guess which one gets to eat today?
0:03:35 > 0:03:38The hyena's powerful bite is half a ton,
0:03:38 > 0:03:40the shark beats that with two tons,
0:03:40 > 0:03:43and the osprey can carry its own bodyweight.
0:03:43 > 0:03:44I'm gonna go with the shark.
0:03:44 > 0:03:46Sounds like good reasoning.
0:03:46 > 0:03:50But they have different amounts to eat in order to win the challenge.
0:03:50 > 0:03:52To help you and everyone at home,
0:03:52 > 0:03:55this fuel gauge will show you how our hunters are getting on.
0:03:55 > 0:03:58The first one to hit full is our winner.
0:03:58 > 0:04:02All will be revealed as we recreate a day in the lives of our contenders
0:04:02 > 0:04:06as they battle to earn the title of most powerful natural born hunter.
0:04:13 > 0:04:15This is our female hyena.
0:04:15 > 0:04:19She hasn't fed properly for three days so really needs to hunt.
0:04:19 > 0:04:23She lives with over 60 other hyenas in a loose-knit family group
0:04:23 > 0:04:25called a clan.
0:04:25 > 0:04:28A family that big, they must fight with each other.
0:04:28 > 0:04:31Hyenas have different ranks in the clan based on how powerful they are
0:04:31 > 0:04:36to stop any serious fights. Our mum is near the middle of the pile.
0:04:36 > 0:04:40Order of importance for hyenas is different to other mammal societies.
0:04:40 > 0:04:44- How is it different?- For most mammals, the males are dominant.
0:04:44 > 0:04:47But in hyenas, it's the ladies that rule the roost.
0:04:47 > 0:04:51- They're the top dogs, yeah? - I know they look like dogs,
0:04:51 > 0:04:55- but actually, hyenas are more closely related to cats.- No way!
0:04:55 > 0:04:57After finishing a few scraps,
0:04:57 > 0:05:01our girl's making her way to a couple of new additions to the clan.
0:05:01 > 0:05:04- Hey, two little ones! - They're a couple of months old.
0:05:04 > 0:05:08Our mum and the other females leave their youngsters here in safety
0:05:08 > 0:05:10before starting the job of hunting.
0:05:10 > 0:05:13Like dropping the kids off at nursery before work?
0:05:13 > 0:05:17Exactly. Now Mum's back, they can tuck in to some very special milk,
0:05:17 > 0:05:21jam-packed with energy, four times richer than cows' milk.
0:05:21 > 0:05:23- A hyena milk-shake. - And they need it.
0:05:23 > 0:05:27Mum sometimes leaves the pups for days on end
0:05:27 > 0:05:29when she's on a hunting mission.
0:05:29 > 0:05:32It takes a lot for Mum to make such nutritious milk.
0:05:32 > 0:05:35Without a decent meal in days, supplies are running low.
0:05:35 > 0:05:39Eating one wildebeest calf would replenish her milk stores
0:05:39 > 0:05:42but at this time of year, they could be 50 miles away.
0:05:42 > 0:05:46Let's get better acquainted with our great white shark.
0:05:46 > 0:05:49Just one? Where's the rest of the family?
0:05:49 > 0:05:50Great white sharks live alone.
0:05:50 > 0:05:54Our female's been swimming the vast oceans all on her own
0:05:54 > 0:05:56since the moment she was born.
0:05:56 > 0:05:59Mum didn't feed her or teach her how to hunt?
0:05:59 > 0:06:02No, she's had to learn all that for herself.
0:06:02 > 0:06:06But these guys are natural hunters. She should have no problem eating.
0:06:06 > 0:06:09You'd think so, but she hasn't eaten for two months!
0:06:09 > 0:06:11I thought I heard her belly rumble!
0:06:11 > 0:06:14She can go for three months without food,
0:06:14 > 0:06:18but she's pregnant with 15 baby sharks and is really hungry.
0:06:18 > 0:06:2015? She'll need a big breakfast.
0:06:20 > 0:06:25She won't make breakfast. She needs to get to the South African coast
0:06:25 > 0:06:29where a big seal will satisfy her hunger. But she's a long way off.
0:06:29 > 0:06:31We'll come back to her in a bit.
0:06:32 > 0:06:35Time to check in with our osprey.
0:06:35 > 0:06:39- More of a typical family set-up here, I see.- Yes.
0:06:39 > 0:06:42- We've got Mum, Dad and three chicks. - Happy families!
0:06:42 > 0:06:46Looks dangerous for youngsters to be messing around on.
0:06:46 > 0:06:50It is quite high, but they're safe from any predators on the ground.
0:06:50 > 0:06:52Mum keeps a watchful eye on them too.
0:06:55 > 0:06:59- What's Dad up to? - A spot of home improvements.
0:06:59 > 0:07:03- That is one big stick.- Those powerful wing muscles are at work.
0:07:03 > 0:07:04Yes.
0:07:04 > 0:07:08Ospreys add to the existing nest over the years. That nest
0:07:08 > 0:07:12- is over 20 years old and is the size of a double bed!- Cool!
0:07:12 > 0:07:15I always wanted a tree house. Who does the hunting?
0:07:15 > 0:07:17Both parents hunt. But if there are chicks,
0:07:17 > 0:07:21Dad does most of the hunting leaving Mum to serve up dinner
0:07:21 > 0:07:22back at the nest.
0:07:22 > 0:07:25So he needs to catch how many fish?
0:07:25 > 0:07:29There are three chicks, and he's got to provide for Mum
0:07:29 > 0:07:30and grab a bite himself.
0:07:30 > 0:07:33I reckon six fish today.
0:07:33 > 0:07:34He'd better get cracking.
0:07:34 > 0:07:36Conditions are looking good.
0:07:36 > 0:07:40It's time for Dad to flex those powerful flight muscles
0:07:40 > 0:07:41and find some fish for the family.
0:07:41 > 0:07:44We'll bring you the action as soon as it happens.
0:07:49 > 0:07:51Now you know a bit more about our contenders,
0:07:51 > 0:07:55- do you want to change your mind, Barney?- I'm sticking with the shark.
0:07:55 > 0:07:56OK. Fair call.
0:07:57 > 0:08:00Let's catch up with our hyena.
0:08:00 > 0:08:03Mum's spending a few moments in the den suckling the pups.
0:08:03 > 0:08:06She's off hunting, and could be gone for days.
0:08:07 > 0:08:10- Does she go with the rest of them? - Normally she'd go with a few others
0:08:10 > 0:08:14in a small pack, but most of the clan have already left.
0:08:14 > 0:08:15So today she's on her own.
0:08:15 > 0:08:19It makes hunting more difficult, but she'll get all of the rewards.
0:08:19 > 0:08:23So this is where the power comes in because she's hunting alone.
0:08:23 > 0:08:26She can take prey more than three times her size.
0:08:26 > 0:08:28You saw the bone-crushing power in her jaws.
0:08:28 > 0:08:31But the real power in hyenas comes from their heart.
0:08:31 > 0:08:34It makes up about ten per cent of their body weight,
0:08:34 > 0:08:3630 times more than ours.
0:08:36 > 0:08:39That's enormous. That's one powerful engine.
0:08:39 > 0:08:43Exactly. That heart can keep her on a steady trot for ten miles,
0:08:43 > 0:08:46wearing down prey like young wildebeest.
0:08:46 > 0:08:51- Are babies easier to catch? - They're easier than an adult,
0:08:51 > 0:08:55but wildebeest calves are no pushover. Within minutes of birth,
0:08:55 > 0:08:58they're walking and running along with Mum
0:08:58 > 0:09:02and over a million wildebeest who are keeping an eye out for danger.
0:09:02 > 0:09:05A million? She doesn't stand a chance of getting close.
0:09:05 > 0:09:08Armed with her bone-crushing jaws and that powerful heart,
0:09:08 > 0:09:12- she has a good chance. Unless... - What?
0:09:12 > 0:09:15- That is a lion.- The "mane" event!
0:09:15 > 0:09:20- (Lions have manes.)- Anyway, lions and hyenas don't get on. In fact,
0:09:20 > 0:09:23they're arch enemies and will often fight to the death.
0:09:23 > 0:09:27These lions have invaded her clan's patch.
0:09:27 > 0:09:30The pups aren't far away and are in potential danger.
0:09:30 > 0:09:32A powerful hyena can see off a lion, surely?
0:09:32 > 0:09:35Not on her own. Lions are four times bigger than her.
0:09:35 > 0:09:38Hyenas rely on strength in numbers for protection.
0:09:38 > 0:09:40Most of the clan are away hunting.
0:09:40 > 0:09:43- This is disastrous. - She's calling for back-up.
0:09:43 > 0:09:47With her pups in danger, she won't back down without a fight.
0:09:51 > 0:09:54This is a regular face-off.
0:09:55 > 0:09:58Two of Africa's most powerful animals going head-to-head.
0:10:01 > 0:10:06- But they've done enough to put the lions off - for now.- That was close.
0:10:06 > 0:10:10Our mum has to wait until the lions have left before it's safe to hunt.
0:10:10 > 0:10:13Until then, let's catch up with our shark.
0:10:14 > 0:10:18Our soon-to-be mum is still 12 miles away from the South African coast
0:10:18 > 0:10:21and hasn't eaten for two months.
0:10:21 > 0:10:25She's powering along. That must use up loads of energy.
0:10:25 > 0:10:28Hang on, it's barely changed since this morning.
0:10:28 > 0:10:32- She's already swum 12 miles. How can that be?- That's because
0:10:32 > 0:10:35she is the ultimate predator when it comes to swimming.
0:10:35 > 0:10:38She has special scales called denticles.
0:10:38 > 0:10:40These denticles reduce drag
0:10:40 > 0:10:43and her torpedo-shaped body means she's super-streamlined
0:10:43 > 0:10:45cutting through water with ease.
0:10:45 > 0:10:50- Like her teeth cutting through her dinner.- She can't use her jaws yet.
0:10:50 > 0:10:54She's got to get to the coast first. She should arrive late afternoon,
0:10:54 > 0:10:58the perfect time to set her ambush. We'll catch up with her in a bit.
0:10:59 > 0:11:02Back in Canada, our dad has found the perfect place
0:11:02 > 0:11:04to do a spot of fishing.
0:11:04 > 0:11:08- It sounds quite relaxing. - Not for an osprey.
0:11:08 > 0:11:12Plunging underwater is seriously dangerous when you can't swim.
0:11:12 > 0:11:16So it needs powerful flight muscles to haul itself out of the water.
0:11:16 > 0:11:18But they're not just for getting out of water.
0:11:18 > 0:11:22Ospreys fly between Canada and South America every year
0:11:22 > 0:11:23to find the best fishing spots.
0:11:23 > 0:11:27That's 200,000 miles in their lifetime -
0:11:27 > 0:11:29almost as far away as the moon!
0:11:29 > 0:11:33Hats off to the osprey. They are powerful flying machines.
0:11:33 > 0:11:37Another weapon is their razor-sharp eyesight.
0:11:37 > 0:11:39Our dad has spotted a potential meal
0:11:39 > 0:11:42from half a football pitch above the water.
0:11:49 > 0:11:54Wow! That was sheer power. That was awesome!
0:11:54 > 0:11:56Dad takes breakfast to his favourite perch,
0:11:56 > 0:11:59grabbing a quick bite for himself.
0:12:00 > 0:12:03But Mum has other ideas. The kids need it more
0:12:03 > 0:12:06and she makes her feelings vocal, telling Dad to head home.
0:12:07 > 0:12:10He drops off fish number one with Mum to feed the kids
0:12:10 > 0:12:13and goes off in search of another.
0:12:13 > 0:12:18So he's on the hunt again already. He's powerful but also super-quick.
0:12:18 > 0:12:23Barney, let's see that incredible hunting technique in closer detail.
0:12:23 > 0:12:26Phase one: surveillance. He flies round
0:12:26 > 0:12:29searching for a fish. Once the target is in sight,
0:12:29 > 0:12:32he hovers to get a better look at the prey.
0:12:32 > 0:12:34Phase two: the stoop.
0:12:34 > 0:12:37With the fish located, he folds his wings back
0:12:37 > 0:12:40to drop down at speeds of up to 45 miles an hour.
0:12:40 > 0:12:42Phase three: impact.
0:12:42 > 0:12:46Just before he hits the water, he swings his feet into position
0:12:46 > 0:12:50- which are a properly cool gadget. - What's cool about them?
0:12:50 > 0:12:51Unlike most birds of prey,
0:12:51 > 0:12:55the osprey can actually twist its outside toe from front to back.
0:12:57 > 0:13:00Two at the front and two at the back for better grip.
0:13:00 > 0:13:03A double-jointed fishing bird!
0:13:03 > 0:13:06- Ooh, he's disappeared.- That is the most dangerous part of the hunt.
0:13:06 > 0:13:09Once his talons are in, it's difficult to let go.
0:13:09 > 0:13:14Since he can't swim, he only has a second or two to drag himself back
0:13:14 > 0:13:17out of the water. Special pads on his feet help grip the fish
0:13:17 > 0:13:21and he even turns the fish round, head first, in mid-air.
0:13:21 > 0:13:23Like a jet with rockets pointing forwards.
0:13:23 > 0:13:26Both designed for streamlined flying.
0:13:26 > 0:13:30It's breathtaking to watch, but he's still got four more fish to find
0:13:30 > 0:13:33if he's going to feed the whole family.
0:13:34 > 0:13:37A couple of hours later and our girl's getting very close.
0:13:37 > 0:13:40Time for another weapon to come into action -
0:13:40 > 0:13:42her powerful sense of smell.
0:13:42 > 0:13:45It's about 10,000 times more sensitive than ours
0:13:45 > 0:13:48and can detect prey from three miles away.
0:13:48 > 0:13:51She'll even stick her head out of the water
0:13:51 > 0:13:53in order to sniff around.
0:13:53 > 0:13:58- She can smell above the water, too? - Smell travels faster through air than water.
0:13:58 > 0:14:02It's thought she does this to smell her prey from further away.
0:14:02 > 0:14:06But she can also see further, too. It's called spy-hopping.
0:14:06 > 0:14:10She'll pick up a meal here. Look at all those seal meal deals!
0:14:10 > 0:14:13But while they may look slow and cumbersome on land,
0:14:13 > 0:14:16believe me, they are perfectly adapted for life in the water.
0:14:16 > 0:14:19And with so many eyes looking out for danger,
0:14:19 > 0:14:22it'll make our girl's job a whole lot harder.
0:14:24 > 0:14:26Time to check on the state of play.
0:14:26 > 0:14:27There's our hyena mum.
0:14:27 > 0:14:30After a run-in with the local lion pride,
0:14:30 > 0:14:32her energy is running even lower.
0:14:32 > 0:14:35And she hasn't fed for three days.
0:14:35 > 0:14:37And she still has the power to keep going.
0:14:37 > 0:14:40Our great white shark hasn't eaten for two months
0:14:40 > 0:14:42and is in need of food.
0:14:42 > 0:14:45But she still has a couple of miles to go to reach it
0:14:45 > 0:14:47before even thinking of catching it.
0:14:47 > 0:14:49I still reckon the shark's gonna win.
0:14:49 > 0:14:52Don't forget the osprey has already caught two fish.
0:14:52 > 0:14:55- But he's got loads more to catch. - You're pretty certain, Barn.
0:14:55 > 0:14:59But I know you, Steve. You'll throw some spanners in the works.
0:14:59 > 0:15:01You're gonna jinx it.
0:15:01 > 0:15:05After seeing off the lions earlier, Mum is back to hunting.
0:15:05 > 0:15:07And she's found the wildebeest herd.
0:15:07 > 0:15:10- The chase is on. - More like the trot is on.
0:15:10 > 0:15:13Remember, her hunt is all about stamina.
0:15:13 > 0:15:16That powerful heart maintains a steady trot
0:15:16 > 0:15:19for ten miles, tiring her prey.
0:15:19 > 0:15:23But she can also hit speeds of 40 miles an hour, so she's no slouch.
0:15:23 > 0:15:26Hang on, Steve. Who's looking after the kids?
0:15:26 > 0:15:30Good question. The mums who've already eaten are back at the den,
0:15:30 > 0:15:32looking after all the pups.
0:15:32 > 0:15:34But they only suckle their own.
0:15:34 > 0:15:37Our two are getting very hungry
0:15:37 > 0:15:39so Mum had better get a shift on.
0:15:40 > 0:15:42It's close. Oh, she's got one.
0:15:42 > 0:15:46If she can keep a hold of it, she'll get enough to be our winner.
0:15:50 > 0:15:51Oh, who's this?
0:15:51 > 0:15:53This is one of the other clan members.
0:15:53 > 0:15:57Both are hungry. There's no point in fighting over her kill.
0:15:57 > 0:15:59Our mum will just have to gorge down what she can.
0:15:59 > 0:16:03- But it's just got a whole lot worse. - What now?
0:16:03 > 0:16:06The two lions from the pride have turned up and they're hungry.
0:16:06 > 0:16:09Our mum's hungry, too, but she's no match for them.
0:16:09 > 0:16:11Time to grab what she can and leg it.
0:16:11 > 0:16:14Lions are becoming a bit of a nuisance.
0:16:14 > 0:16:18She needs a lot more food to make the high-energy milk for her pups.
0:16:18 > 0:16:22While she looks for another meal, let's check out our shark.
0:16:22 > 0:16:25Our shark has arrived at the South African coast
0:16:25 > 0:16:29and only has one thing on her mind. Seals.
0:16:29 > 0:16:32I'm not surprised. I'd eat a seal after two months without food!
0:16:32 > 0:16:34The seals are safe on dry land.
0:16:34 > 0:16:38But our pregnant mum knows they need to feed in open water.
0:16:38 > 0:16:42That's when they enter the great white's world.
0:16:42 > 0:16:44But it's an evenly-matched battle.
0:16:44 > 0:16:47Surely those powerful jaws are like a seal blender?
0:16:47 > 0:16:51Razor-sharp teeth and a two-ton bite are only useful
0:16:51 > 0:16:53if she can get close enough.
0:16:53 > 0:16:55Seals are difficult to catch,
0:16:55 > 0:16:58twisting and turning their way out of danger.
0:16:58 > 0:17:00She has to get really close without being spotted
0:17:00 > 0:17:03so has a nifty trick up her sleeve.
0:17:03 > 0:17:06Brilliant. Can't even see her sleeves!
0:17:06 > 0:17:08Take a look at her colouration.
0:17:08 > 0:17:12Dark on top and light on the bottom. A lethal weapon.
0:17:12 > 0:17:16- How can colour be lethal?- From above, sharks can't make her out
0:17:16 > 0:17:19because she looks like the murky water. And from below,
0:17:19 > 0:17:23it helps make her look like the bright sky above.
0:17:23 > 0:17:25- Ah, the perfect disguise.- Exactly.
0:17:25 > 0:17:29So she can get into the perfect ambush position
0:17:29 > 0:17:30without being seen.
0:17:30 > 0:17:34It's then just a question of waiting for the right moment.
0:17:34 > 0:17:39A seal that drifts from the safety of the group is in serious danger.
0:17:39 > 0:17:42I actually am on the edge of my seat, here.
0:17:46 > 0:17:51Two fish down, but our dad still needs another four to win.
0:17:51 > 0:17:55- He's not wasting any time. - He's having the time of his life!
0:17:56 > 0:17:58He makes it look easy,
0:17:58 > 0:18:03but using those powerful flight muscles to get out of the water
0:18:03 > 0:18:05is eating into his energy levels.
0:18:05 > 0:18:07Yeah, look at the fuel gauge.
0:18:07 > 0:18:10Next time, he'd better grab one for himself.
0:18:10 > 0:18:13I think that's exactly what he's thinking.
0:18:17 > 0:18:20Look at him go! Dad's on a roll. Number four already.
0:18:20 > 0:18:24Yes, things are going well for our osprey. Four down and...
0:18:24 > 0:18:29- And what?- Oh, and trouble. That is a bald eagle.
0:18:29 > 0:18:32He's spotted Dad's fish and now he wants it.
0:18:32 > 0:18:36Pesky eagle-eyed...eagle! But isn't our dad all powerful?
0:18:36 > 0:18:41- Muscles and sharp talons.- But the bald eagle is six times heavier,
0:18:41 > 0:18:43with an even sharper beak and talons.
0:18:43 > 0:18:47Not a bird to mess with. It's now a race to get back to the nest.
0:18:49 > 0:18:53Look at that twisting and turning to get away from that eagle.
0:18:53 > 0:18:58So manoeuvrable, but the strength of the eagle is much more impressive.
0:18:58 > 0:19:00That was a close call there, Steve.
0:19:00 > 0:19:04This is a regular dog fight. Well, eagle fight.
0:19:04 > 0:19:08- Oh, no, he's dropped it, Steve!- Yes, but he dropped it on purpose.
0:19:08 > 0:19:11He's distracting the eagle so he can make a clean get-away.
0:19:11 > 0:19:15Getting into a potentially deadly aerial battle was too risky.
0:19:15 > 0:19:19- And he's still OK to hunt.- But that must have used up a lot of energy.
0:19:19 > 0:19:21He'll have to rest up for a while.
0:19:21 > 0:19:23I thought he'd nabbed fish four.
0:19:23 > 0:19:25Unfortunately not. He's down to three.
0:19:30 > 0:19:34After losing her last meal to some lions,
0:19:34 > 0:19:39our mum's locked onto a new target, a baby Thomson's gazelle.
0:19:39 > 0:19:42It's the perfect meal for a tired hyena.
0:19:42 > 0:19:44It could be game over, then.
0:19:55 > 0:19:57She's looking tired, Steve.
0:19:57 > 0:19:59I think she's too exhausted to carry on.
0:19:59 > 0:20:03But the clan leader and her side-kick have just turned up.
0:20:03 > 0:20:06Brilliant. Back-up when you need it.
0:20:07 > 0:20:11They're all from the same clan, but the clan leader is hungry
0:20:11 > 0:20:14and outranks our mum. When your boss is in town,
0:20:14 > 0:20:18it means you sometimes just have to go hungry.
0:20:18 > 0:20:21- But her pups depend on her. - I'm afraid it's just as I thought.
0:20:21 > 0:20:24She'll have to start all over again.
0:20:25 > 0:20:27After careful searching,
0:20:27 > 0:20:31our shark's spotted a potential meal - a lone seal.
0:20:31 > 0:20:34And a chance to spring the trap.
0:20:34 > 0:20:36With her target in sight,
0:20:36 > 0:20:38she sneaks below the other seals.
0:20:38 > 0:20:41- I love it. A lone shark after a lone seal.- Right.
0:20:41 > 0:20:44After a couple of swim-bys, she's locked onto the target.
0:20:46 > 0:20:49She turns her body to burst up from directly below,
0:20:49 > 0:20:51making her virtually impossible to see,
0:20:51 > 0:20:54so she can follow the seal whichever way it turns.
0:20:54 > 0:20:57There's very little chance of escape.
0:20:57 > 0:20:59She's in position.
0:21:00 > 0:21:03- Just a dark silhouette above her and bam!- Did she get it?
0:21:03 > 0:21:09She's breached clear out of the water. I've no idea what's happened.
0:21:09 > 0:21:11But it looks like the seal's got away.
0:21:13 > 0:21:16Not only that, but they're chasing after her.
0:21:16 > 0:21:19Have they got a death wish or something?
0:21:19 > 0:21:23It may look dangerous, but it means they don't lose her.
0:21:23 > 0:21:26They can keep an eye on her and that's confusing for our shark.
0:21:26 > 0:21:30Her eyesight is ten times better than ours in low light,
0:21:30 > 0:21:31but the sun is fading fast.
0:21:33 > 0:21:35With so many seals on her case,
0:21:35 > 0:21:40she cuts her losses, saving her energy for a hunt early tomorrow.
0:21:40 > 0:21:45So have I got this wrong again? Is that it for our shark?
0:21:45 > 0:21:49Yes, it is. But she'll be back first thing in the morning
0:21:49 > 0:21:51and I'm sure her power will get her a meal.
0:21:51 > 0:21:53I've got no idea who's gonna win now.
0:21:56 > 0:21:59OK. One down, two to go.
0:21:59 > 0:22:03For the hyena and the osprey, the battle for victory continues.
0:22:04 > 0:22:07Our hyena mum hasn't fed for three days,
0:22:07 > 0:22:11trekked a marathon, lost out on two meals, but still powers on.
0:22:12 > 0:22:15Whereas our osprey dad got off to a great start,
0:22:15 > 0:22:19catching three fish, but lost his last one to a bald eagle
0:22:19 > 0:22:21and still has another three fish to grab.
0:22:21 > 0:22:23This couldn't be any closer.
0:22:23 > 0:22:27Our dad's taking advantage of the light and wind
0:22:27 > 0:22:29in the latter part of the day.
0:22:29 > 0:22:33- I like this guy. He's on fine form. - He sure is.
0:22:33 > 0:22:36Light winds means it's easier to control the dive
0:22:36 > 0:22:39and the light's good too, with less glare on the surface.
0:22:39 > 0:22:41And boy, does he go for it.
0:22:42 > 0:22:46- Superb. How many has he caught now? - That's his fourth of the day.
0:22:46 > 0:22:49But still two more to go.
0:22:49 > 0:22:53- If he keeps up this impressive display, he'll walk it.- Fly it!
0:22:53 > 0:22:57The chicks look well fed now. The last two are for Mum and himself.
0:22:57 > 0:22:59He's straight back out on the case.
0:23:01 > 0:23:04After losing out twice earlier,
0:23:04 > 0:23:06Mum just needs one big meal for herself.
0:23:06 > 0:23:10I have to say, her determination is almost as impressive as her power.
0:23:10 > 0:23:14But she hasn't had much luck. If she can get something and keep it,
0:23:14 > 0:23:18- we'll have our winner. - OK. Eenie, Meenie, Minie, Moose.
0:23:18 > 0:23:20She needs to lock onto a target and go for it.
0:23:20 > 0:23:24I reckon that young wildebeest is in big trouble.
0:23:24 > 0:23:26- That could be slow.- Could be.
0:23:29 > 0:23:32- She's gaining on that one. - Zeroing in. Yes.
0:23:32 > 0:23:34She's picked it out from the herd.
0:23:34 > 0:23:37Now it's all down to stamina. She's got to run it down.
0:23:38 > 0:23:40Hang on, who's that?
0:23:40 > 0:23:42It's the lion!
0:23:42 > 0:23:46Not again! I tell you, our hyena is just cursed.
0:23:46 > 0:23:49- She's stolen the meal? - It's an easy meal for a lion.
0:23:49 > 0:23:54Our hyena is left empty-handed. But she's not done yet.
0:23:54 > 0:23:58Her main weapon is power. All she needs now is some back-up.
0:23:59 > 0:24:02Our dad just needs two more fish.
0:24:02 > 0:24:05- Light's fading fast so he's got to be quick.- Incredible.
0:24:05 > 0:24:09He's stooping, he's in, he's got it, his fifth. One more to go.
0:24:09 > 0:24:14- Surely nothing can stop him now? - Oh, no, not another interloper!
0:24:14 > 0:24:18- It's not a bald eagle, is it? - No, it's a black-backed gull.
0:24:18 > 0:24:21He's got some tips from the eagle about how to rob the dinner!
0:24:21 > 0:24:23They nick my chips at the seaside.
0:24:23 > 0:24:25- He's still got it, though.- He has.
0:24:25 > 0:24:28This is just incredible.
0:24:28 > 0:24:31Look at those twists and turns over the water.
0:24:31 > 0:24:34- Oh, that's close. - Almost grabbed his tail there.
0:24:34 > 0:24:39- Go on, Dad!- Go on, Dad! Oh, he's dropped it again!
0:24:39 > 0:24:42And the seagull's got some easy pickings.
0:24:43 > 0:24:46Our lion is tucking into the food,
0:24:46 > 0:24:48but the hyena numbers are growing.
0:24:48 > 0:24:52- That lioness is seriously outnumbered.- The hyenas know it.
0:24:52 > 0:24:56- So our mum's gonna get her meal. Brilliant.- Let's see what happens.
0:24:59 > 0:25:03The lioness looks like she's had enough and is giving up.
0:25:03 > 0:25:06Yes, the hyenas are tucking in. Let's see how the fuel gauge goes.
0:25:06 > 0:25:10It's moving up. I don't think the osprey can catch her.
0:25:10 > 0:25:11Let's see.
0:25:15 > 0:25:19Despite those gulls, our osprey heads in for another try.
0:25:19 > 0:25:23- Bam into the water. Has she got one? - Hang on, no!- She didn't catch one.
0:25:23 > 0:25:27She's shaking her feathers free of water, getting back into the air.
0:25:27 > 0:25:30Now our hyenas are really tucking in.
0:25:30 > 0:25:34- Let's see how that fuel gauge is going.- Almost full.
0:25:34 > 0:25:36Can't see the osprey coming back, Steve.
0:25:36 > 0:25:38A bit more and she can go home.
0:25:38 > 0:25:41Dad's putting all his weapons into action.
0:25:41 > 0:25:43Just two more for the win.
0:25:43 > 0:25:46I don't think he has time, Steve.
0:25:46 > 0:25:49This one is a nail-biter.
0:25:56 > 0:25:58Oh, no, the lions are back!
0:25:58 > 0:26:03This is a male lion that's been called in. He sees off the hyenas.
0:26:03 > 0:26:05That is an angry cat. I wouldn't mess with him!
0:26:05 > 0:26:08Have they managed to eat enough, though?
0:26:08 > 0:26:12- It's ever so close, but not quite. - I can't take any more!
0:26:12 > 0:26:16She's not finished yet. She has to hope the lion leaves some scraps.
0:26:17 > 0:26:19Just one more fish
0:26:19 > 0:26:22as the sun goes down. He's caught it,
0:26:22 > 0:26:24- but can he get out of the water? - Oh, no!
0:26:24 > 0:26:26Come on, you're doing so well.
0:26:26 > 0:26:29All those hunts have drained his energy.
0:26:29 > 0:26:31He's stuck. He really can't get out.
0:26:31 > 0:26:34He has to take off or he'll drown.
0:26:34 > 0:26:36The power of those wings, getting him out.
0:26:36 > 0:26:41He's dragging himself out. I didn't think he had it in him, Steve.
0:26:41 > 0:26:44No! Here comes another gull. Can he get free?
0:26:44 > 0:26:47- Nearly there!- Back to the nest! - Come on, Dad!
0:26:49 > 0:26:52He's just holding on.
0:26:52 > 0:26:55And yes! There we have it, ladies and gentlemen. Our winner!
0:26:55 > 0:26:58The fuel gauge is full.
0:27:00 > 0:27:02Commiserations to our runners-up.
0:27:02 > 0:27:05Our hyena should get more scraps after dark
0:27:05 > 0:27:07and she will be able to feed her pups.
0:27:07 > 0:27:10Our shark only had one chance of a meal,
0:27:10 > 0:27:13but the seals proved too difficult in the end.
0:27:13 > 0:27:16She'll be ready at first light, when she might have more luck.
0:27:16 > 0:27:21The osprey may not be the biggest, but it punches well above its weight
0:27:21 > 0:27:23and is our deserved winner,
0:27:23 > 0:27:27earning the title of most powerful natural born hunter.
0:27:27 > 0:27:30Join us next time when we'll seek out three more contenders
0:27:30 > 0:27:33to earn the title of Natural Born Hunter.
0:27:33 > 0:27:36Until then, goodbye! I need to lie down!
