A mother, black bear, is looking for something suitable for her cubs.
This is their first ever trip to the seaside.
In a few hours, the tide will return.
So they must keep up with mum.
Meat crabs can give a nasty nip.
So it's best to start off with smaller ones.
During spring, three quarters of the bear's food comes from the beach.
But now, this family is not alone.
He's double her size and they're in his temperature.
It's time to head for safety.
Bears have poor eyesight,
but their sense of smell is acute
and the male has detected intruders.
He knows exactly which tree they are in.
If the cubs stay up there, they'll be safe,
but they're losing precious feeding time.
For now, he's content to leave his scent mark.
a warning note for trespasses.
For the Cubs, lunch today will have to be a takeaway.
and within minutes, feeding time is over for another day.
With higher water, the mother bear has moved to the falls,
where the salmon are most active.
But the big male has taken over the best fishing spot.
She needs to keep herself safe
But she also needs access to salmon.
She cautiously moves closer to the big male.
She's probably still a little unsure of him after their last encounter.
There's lots of salmon swimming through the falls now,
but with the big male so close by,
she can't really move around as freely as she needs to.
The big male has control of the best fishing site.
But due to the closeness of the mother bear,
he also seems to be losing some of his focus.
Then he manages to grab another salmon.
However, this one is a male, and he lets it go.
The mother bear is less fussy right now,
but she's unable to take advantage of the opportunity.
Neither bear is very happy with the presence of the other.
The mother bear decides to move in and take advantage of the scraps the big guys left behind.
The big male seems annoyed by her presence so close behind him.
At this rate, neither bear is going to be successful.
The mother is getting more confident,
growling at the big male,
letting him know she wants him out of there.
Finally, she builds up the nerve to storm his position.
Even though she's much smaller than him, she's not backing down.
She wants access to the salmon more than he does.
The big male tries to intimidate her with as much larger size,
but she holds her nerve, refusing to leave.
Finally, the big males had enough and moves on to other fishing grounds.
Now the mother bear has the falls all to herself.
This has been a hard one salmon,
but I think there's going to be lots more where this came from now.
China is some of the world's most abundant and diverse bamboo forests.
In the giant panda park, they are critically important,
supplying 99% of the panda's diet,
making it the perfect place for a mother to raise her cup.
With each passing day, this youngster is being prepared for adult life.
Today's lesson is how to eat bamboo.
It's not as simple as it sounds.
The cane must be split perfectly.
The most digestible part is inside.
The enormous jaw muscles needed to crunch bamboo
A what give pandas their characteristic round faces.
The youngster practices on a stick.
As an adult, she'll eat 40 kilograms of bamboo a day.
Pandas evolved with the carnivores digestive system,
which means they are born lacking the key plant processing gut bacteria they need.
A seemingly affectionate exchange between mother and baby
may be a way of passing her cub crucial bamboo digesting microbes
When the cup is weaned at around 18 months,
they will separate, and the youngster must go it alone.
Exhausted from his swim, the bear must regain his strength.
The next day, a sea fog shrouds the island.
The Wallace's sense that they're in danger.
Using the fog as cover, the bear approaches the herd.
The adults close ranks around their young,
presenting a wall of blubber and hide.
He tests the banner, but it stands firm.
It appears that the world's largest land carnivore has met his match.
There must be a chink in the armour somewhere.
This female walrus is shielding her pup if he can just prize her off.
The bear's claws and teeth can't penetrate her thick hide.
With the herd retreating to water, the bear must move quickly.
Having failed with one, he heads straight for another.
The chance of his first meal in months is slipping away.
He seems increasingly desperate.
He must avoid the stabbing tusks if he's the wind.
The flailing walrus is immensely powerful
and drags the bear away from the shallows towards the safety of the herd.
Forest once covered 80% of Europe.
Now, only half of it remains.
One of only 1,500 that are left in Finland's forests.
Her cubs have recently emerged from their nursery den.
The long summer days means there's plenty of time for play.
...a... ...a... ...a... ...a... ... ... ... ... ... ... ... ... ... ...
With two boisterous cubs,
it pays to rest whenever you can.
But their mother must be on her guard.
The cubs have spotted something.
A large male, looking for a mate.
The cubs aren't his, so he might try to kill them.
Their cubs are excellent climbers.
And now they're beyond his reach, 15 meters up.
Their mother warns him to keep his distance.
But the cubs are coming down too soon.
She can't take any chances.
Finland's forests give us a glimpse of what Europe was once like,
a land of endless wilderness where large animals roamed far and wide.
Our male from the camera trap has picked up a scent
and found himself a female.
Due to his small size, this male wouldn't normally have a chance to mate.
This female seems impatient,
and our male doesn't have to be asked twice.
His small size causes a few logistical problems.
But with persistence and the odd leg up,
Mating over, the female grooms the young male.
With no yearlings around, she can afford to spend time with her man.
Each have their own story to tell.
Some are being hand-reared after their mothers rejected them.
Others are temporarily checked over and sent back to mum full of milk.
From newborn to three months old,
they are cared for by specially trained panda nannies.
Just like human babies, they need regular feeding and plenty of sleep
to prepare their little bodies for growing up.
At 40 days old, this youngster has opened its eyes
and is already five times heavier than when it was born.
This is down to fat rich milk, and at this age, they get it five times a day.
Milk is baby food for now. After six months, they will also be able to eat solids.
For pandas, that means bamboo.
And she doesn't wait long. With no other bears around, she makes the move.
This is a big moment in the Cubs' lives. She's got to be careful, though.
Another bear could turn up at any moment. The Cubs are a bit nervous being out on the creek,
and they know they have to stick close to her wherever she goes.
While there are still lots of salmon around,
the mother bear can be selective with what she eats.
She takes a bite of this salmon and then drops it,
as she can probably tell from the taste it's a male.
Bears need to target the richest, most nutritious food source.
What she really wants to find are female salmon,
and she'll go out of her way to catch one.
Female salmon are loaded with thousands of brightly colored, nutrient-rich eggs.
This is the best part of the salmon, high in calories and fat,
and she doesn't want to leave any behind.
The cubs, though, still need to learn which are the best parts to eat.
Though the cubs are still nursing, they need these protein-rich salmon as much as their mum does.
The whole family has to put on as much weight as possible before winter hibernation.
The mother bear is always alert to potential dangers to her cubs.
Surprisingly, it's another ghost bear.
This one looks like a large male.
The cubs know that when another bear is around,
they have to get out of there.
They retreat to the safety of the trees.
The mother bear is much smaller than him,
but she's still going right after him.
I'm not sure that's such a good idea.
He could certainly do some damage to her,
and he doesn't seem much deterred by her approach.
That's a risky move on her part.
Anytime two bears physically interact like that, there's a good chance one of them could be hurt.
They're very powerful animals.
I don't know her character well enough yet to decide if she's foolhardy or brave, only
But her cubs knew what to do in this situation.
They knew that their best defense was to get up as high into a tree as quickly as possible.
Meadows that only a few weeks ago were buried beneath the snow are now full of life.
But in these mountains, the good times will not last long.
So the bears must feed as fast as they can.
During the summer months, an adult can put on 180 kilos,
gorging on plants, and, if they can catch them, a marmot or two.
But just now, the bears have something else on their minds.
It's becoming warmer, and the bears are keen to shed their thick winter coats.
Mothers show the cubs what to do about this.
Some trees, it seems, are particularly suitable for rubbing.
Bears have their favourites and will travel long distances to visit them.
Some itches just have to be scratched.
There are now around 30 bears in this one valley.
As they rub, each leaves an individual and recognisable scent.
So the tree soon carries a list of who's around,
which might help individuals to avoid a fight.
To best spread their scent, they really have to put their back into it.
It is satisfactorily scratched.
In a couple of months, they will have to return to their dens to hibernate.
So now they must put on as much weight as they can.
At this time of year, polar bears, on average, succeed only once in 20 hunts.
If the hunter is skinny, like this one, that may not be often enough.
All she can do is keep trying.
To prevent her scent, she makes a wide sweep to get down wind of the seal.
Getting close, she's now right behind the seal.
Incredibly, she caught the seal underwater.
It's only small, but even so, its blubber alone will contain a hundred thousand calories,
enough to sustain this bear for a week.
And in that time, she might even catch another.
But this can't go on forever.
As summer continues, temperatures are rising.
Each hunt requires more energy, draining the bears of their reserves.
One of the most successful snow animals is solitary and lives most of his life alone.
They can be found in the very far north of the Arctic, the polar bear.
This male, like every polar bear, is almost completely covered in fur.
But his secret to staying warm in this frozen land is actually inside his large body.
He has a huge layer of insulating fat, about 10 centimetres thick.
It traps heat, keeping him warm from the inside.
To maintain this fat, he relies on his good hunting skills.
His prey is hidden under the thick ice.
Luckily, he has a secret weapon to help him hunt.
An extraordinary sense of smell,
a hundred times stronger than ours.
He can detect a seal carcass from 30 kilometers away
and under a meter of snow.
success. He will eat all the fat of a seal first,
often leaving the actual meat. This extreme fatty diet
would kill us, but for the polar bear it's essential.
Indeed, they are one of the fattest mammals on earth.
Their incredible insulation and intense sense of smell
make the polar bear a master in the snow.
They're also built to move around effortlessly in this snowy environment, unlike me.
I am a perfect example of an animal that is not adapted for walking about a snowy environment like this.
I'm 12 stone, 12 and 1 half stone, and all of my weight is distributed.
onto my feet. Size 12, big feet for a human,
but not big enough to stop me from sinking down into the snow.
What I need to do is increase that surface area,
I suppose the secret to moving around in deep snow
There we go. Adapted for walking in the snow.
It's easy. I can walk through the forest.
I'm not sinking down into my waist.
I can go fast. I can almost go silently.
Polar bears have built in snowshoes.
Their paws are wide, measuring about 30 centimeters across.
This helps them to distribute their weight evenly on thin ice.
Underneath their large paws are small soft bumps to give them extra grip on the ice.
With little to eat down here, many of Borneo's terrestrial mammals are smaller than on mainland Asia.
Confined to her protected forest sanctuary, the exceedingly rare Bornean sun bear.
Just over a metre long, it's the smallest bear in the world.
This fallen branch is a valuable treat.
Filled with wood grubs and beetles, nothing is wasted.
Even a foul-tasting millipede.
But it's not enough to sustain even this little bear.
The real prize sits high above.
Guided by her exceptional sense of smell,
it's the sweet scent of honey.
For larger bears, this beehive may be out of reach.
But being small helps defy gravity.
With sharp claws and rough pads on her feet,
she can ascend 40 meters higher than any other bear to make it in Borneo's jungle
tree tops this miniature acrobat has become more monkey than bear
She needs to put food in the mouths of her two young cubs.
There's a bitter winter coming, and if they're not well fed, her cubs won't make it through.
This is a hard place to be a mum.
This peninsula is home to 200 brown bears.
It's one of the most densely packed populations in the world.
The salmon bonanza has attracted others here too.
Nobody lives permanently in this remote part of Hokkaido.
But one hardy group have special permission to stay here for some of the year.
Hokkaido is Japan's second largest island, but the harsh conditions mean it's home to only 4% of its people.
Shiratoko is one of the loneliest corners, where you have to live close to the wild.
Brown bears can weigh 300 kilos and are not to be messed with.
When bears and humans cross paths, things can get dangerous.
But here, something astonishing has happened.
For the fishermen, bears have become a part of everyday life.
It takes some nerve, but the men live alongside them as equals.
Tough characters, side by side, both dependent on the summon run.
The mother bear knows what she's doing.
Survival is in her blood.
Her ancestors came to Hokkaido from Siberia,
12,000 years ago, Hokkaido was joined to the Russian mainland.
Siberian animals colonized it before the sea levels rose,
turning Hokkaido into an island.
It's why the wildlife here is so different from the rest of Japan
and so well equipped to face the coming winter.
Initially, this was just a stopover as he ventured east,
but the creatures on Sulawesi was so curious and unique,
he returned a further three times.
This amazing island is where I pick up his story.
And with the help of my guide, Bobby,
I'm searching for a tree-dwelling creature
that would become a key piece of his evolutionary puzzle.
So Bobby, how do you find a bear cuss-cus?
So I've written sniff out.
That's the first time I've ever seen one of these creatures, a bear cuscus.
And they are quite extraordinary, they're unique.
You only find them here in Sulawesi.
I've seen other kinds of cus throughout Indonesia.
But this one is the only one that moves around during the day,
so it's a lot easier to see.
His face resembles quite a cross, sloth.
Slose, quite benign, almost sleepy looking.
But these look, just like they're angry about something.
And in fact, these are supposed to be active during the day,
but I mean, that's really active, is it?
He scratched his ear once.
That's really at the low end of active.
What excited Wallace about this lazy cus,
a relative of Australian mammals like kangaroos
that carry their young in pouches.
And these weren't the only Australian creatures on this island.
He also came across Australian birds, like cockatoos.
Wallace was starting to see a pattern.
Well, thank you everyone for coming out to our World Bair Day documentary study.
This has been, you know, a beautiful documentary that we've all sat here and watched together.
Look for the bare necessities, the simple bare necessities.
Forget about your worries and your stride.
I mean the bare necessities or Mother Nature's recipes
that bring the bare necessities of life.
Wherever I wander, wherever I roam,
I couldn't be found of my big home.
The bees are buzzing in the tree to make some honey just for me.
When you look under the rocks and plants and take a glance at the fancy ants,
The bare necessities of life will come to you.
Look for the bare necessities, the simple bare necessities.
Forget about your worries and your strike.
I mean the bare necessities.
That's why a bear can rest at ease with just the bare necessities of life.

But, you know, Bobo will eventually flip Disney.
That is the target greatest bear in history before Bobo.
He came, you know, when was the jungle book created a long time ago?
60s, maybe even before that.
Look at this animal study.
They are eating wood trees.
That's what they're going to do to Bulls.
