Greatest Fights In The Animal Kingdom Part 4 | BBC Earth - 雙語字幕
If undisturbed, will the beast can drink 8 liters in a single session?
As his confidence builds, he is oblivious to what lurks beneath the surface.
The herd is bewildered, some have never seen a crocodile before.
Even as the There is and foes.
There is great confusion about just what is going on.
And that was just the first attack.
300 hungry crocodiles live in the Grumetty River.
Will the beast react differently to crocodiles and other predators?
Even the adults seem unsure of just how much danger they're in.
The cast desire to pinch his thirst overcomes any fear he may have.
The crocodiles maneuver around them with surprising ease.
They are intelligent hunters plotting their attack with precision.
A strike can happen at any time.
Despite the carnage, the mother and calf survived.
They stampede back onto the planeers.
For the baboons, it's more like a spectator sport.
They might as well settle down a single car.
The clock can take some time to overpower the instinctive.
But crocodiles are cooperative feeders.
They work together.
The death roll breaks the prey into bite-sized chunks.
But aggression can spill over.
Wolves.
These in northern Canada most powerful in the world, and they are setting out to hunt.
The pack is 25 strong, a sign that the prey they are seeking is formidable.
These bison are even bigger than their southern customs and the largest land animals in North America.
For generations, wolves and bison here have been shaped by their battles with each other, making each the most impressive of its kind.
The bison will not stay long among the trees.
They're not safe here.
The wolves are closing in, but their chance of ambushing the bison in the woods has passed.
Their prey are now in the open and bright.
grouped together for safety.
The wolves will need to work as a team if they're to make a kill.
They circle the herd, try to unsettle it and split it up.
But the bison are armed and dangerous.
They will be safe.
as long as they stick together.
The wolves upped their game, harrying the herd, applied to trigger a stampede and spit away one of the smaller ones.
The bison form a defensive circle around them.
their young, horns pointing outwards.
The wolves need a bison to break rank.
But the tables are turning, and now the walls have to retreat.
The pack focused their attention on the rear of the herd and the bison begin to panic.
I'll be back.
A young bison falls behind.
Even this yearling dwarfs the wolves.
Running head down, the herd's only thought is escape.
A stroke of luck for the wolves.
The kill will feed the pack for several days.
But then they will have to resume the chase.
At the frozen ends of our planet, the struggle for survival never eases.
Little fish try to hide amidst the undulating swell of the ocean.
The only cover there is.
It's a game of hide and seek, played out amongst the waves.
Their cover blown.
Escape impossible.
But these particular fish have a unique ability.
Now, flying fish.
With an extra thrust from their tails, the flying fish get airborne once more.
With a good wind, they can glide for hundreds.
hundreds of meters.
It just what the frigate birds have been waiting for.
When frigates join the hunt, the flying fish are literally caught between the devil and the deep blue sea.
If the flying fish get too much lift, they become easier.
as you pray for the Frigates.
If they dive to evade attacks from above, They could fall into the mouths of the Dorado.
You Food is so hard to find this far north that a wolf pack must search hundreds of square kilometers if it's to be successful.
And success means raising the next generation.
To do that here, the wolves must work together.
So the young are raised not only by their parents, but by their aunts and uncles as well.
Together, they try to ensure that each pup reaches near adult size before the snow returns.
The growing pup needs more than just a few leverage.
The wolves need bigger prey,
and to catch that, they hunt as a Adult hairs may be easy to spot, but they're far from easy to catch.
They run at 60 kilometres an hour.
To catch one, the walls work as a team.
Okay.
It's our One of them gets close enough to bite the hair's tail, but a hair can change direction in an instant.
If it can continue to sidestep and jink, it ultimately outlast them.
Finally, it gets away.
For the next hair, the whole pack gives chase.
Now, numbers count.
The walls keep up the pace.
Others on either side, so the hair can't change direction.
A tiny meal for the whole pack.
Kenya, famous for its big cats, the Supreme Hunters.
Cheetahs specialize in hunting at speed.
Though fast, their fragile creatures built to sprint after small prey.
They don't have the strength or weight of a lion to bring down larger animals.
This male is different.
hunt alone.
He's learned that there is strength in numbers.
But here, there are not just two, but three cheaters, a band of brothers.
They have changed their tactics, and by doing so, have taken their prey by surprise.
They and they have they Working together,
they can bring down large prey, an ostrich, a bird that towers over a chinta and is more than twice as heavy.
It can't fly to escape danger but it can lash out with a deadly kick, a female unaware as yet of any danger.
Even with three of them, this is still highly risky.
If one gets injured, the other two couldn't hope to tackle such large prey.
On the other hand, if they get it right, the rewards are huge.
The male has spotted one of the brothers, but only one.
It's not too worried.
Then, suddenly, there are three.
The female is slower to realise the danger, and the cheaters switch targets.
I'm going get of I'm going to get It takes the combined effort and weight of all three brothers to bring down this powerful bird.
Even now, the ostrich could land a fatal kick.
So far the brothers are winning, ostriches have yet to find a way to foil such tactics.
Lions will normally avoid hunting in such heat.
But they're also opportunists.
The lions will need to bring him down quickly before they overheat.
Thanks for Even away from the herd, a bull is a formidable opponent.
It could go and kill a lion.
Oh my You Close to overheating, they finally succeed in bringing him to the ground.
But the massive bull is not giving up.
Against the The full weight of the lions, he regains his feet, and it is now that the tables turn.
Islands are exhausted.
After a 20 minute struggle, only the bull has the energy to finish the fight.
In such exposed and extreme conditions, the challenge for predators and their prey is at its most intense.
I'll see you in the next one.
In the Serengeti, youngsters years watching how old the lioness is tackle large prey.
However, it looks as though these cubs will have to teach themselves through trial and error.
Oh, oh, oh.
They begin the stalk, like seasoned hunters, using the scant cover to conceal themselves.
And they have to be incredibly quiet.
Oryks are spooked by the slightest sound.
I'll see I'll see One of the answers looks as though it's made a mistake.
Actually, very cleverly, it's pushing the oryx towards the other line.
Okay, uhhh uhh, uhhh, uhhh, uhhh, uhhh, uhhh, uhhh, uhhh.
And Oryx is quite capable of seeing off alarm, as long as the antelope sends its ground and doesn't run.
But will the Oryx keep its nerve?
Finally, the youngsters lose heart.
Back in the hive, those bees too young to forage are housekeeping.
Like the Hornet Queen, the Queen Bee has the immeasurable task of laying enough eggs to ensure the health and future of the colony.
The custom of keeping wild Japanese bees is as old as society.
and Yamaguchi has kept bees since boyhood.
Japanese bees are so sensitive that it takes great patience and skill to keep them.
The art of keeping them lies in understanding their behavior.
They make honey stores for the winter.
but they also produce enough for Yamaguchi to harvest.
Japanese may produce less honey than European bees, but the taste is very special.
It's the smell of this growing store of energy-rich honey, which could be there downfall, if it draws in a hornet scout.
But right now, the hornets have other problems to contend with.
The nest is now monstrous.
The workers have excavated over a ton of earth.
There are so many bodies living at close quarters that the Queen and her dynasty are in danger of overheating.
So, workers create air conditioning, keeping a steady flow of fresh air circulating.
Being to cope with high temperatures is a giant hornet's Achilles heel.
The warmth of the hornet's nest belies the change in season.
Seasons change fast up here in the mountains.
And when autumn arrives, there are far fewer insects around.
This me.
my hives are even more vulnerable to attack.
For me, it's an anxious time.
In the search for autumnal food, a scout hornet discovers Yamaguchi's wild bees.
The honeybees fan an alarmed pheromone through the air.
This alerts the whole hive to the hornet's presence.
The scout smells the honeybees.
A prize this rich is worth cent-marking, but unlike the European these Japanese bees do not attack.
Instead, they lure the scout inside.
Still, the bees hang fire.
Then, one It's the signal the others have been waiting for.
Surrounded by vibrating bodies, the hornet at the core of the bee ball begins to overheat.
The bees, the the bees, the bees, bees, bees, bees, the bees, the have the advantage.
A heat tolerance two degrees above that of their enemy.
At 46 degrees Celsius, the aggressor is roasted alive.
The wild bees have spent millions of years living with the enemy.
That's why they alone have developed this extraordinary survival strategy.
