NARRATOR: He is the apex predator
of the Arctic.

Now, the ice bear is under siege.

The threat, an adversary that's deadlier,

more powerful than any he 's ever faced.

A gauntlet of challenges
beyond any the Arctic has dealt him.

After millions of years of ruling the ice,

has the polar bear met his match?

The Arctic ice guards a secret.

Bleak and barren as it seems, it stirs with life.

Just look a little deeper.

To last the year,
the ice bear needs to eat 40 seals.

One more is all it'll take.

Spring is almost over.

If he doesn't catch this one,
he may not survive.

That may be his death knell.

He can 't hunt seals without the ice.

Now the ice is about to disappear.

It's late June.

A few generations ago,
the ice bear would have had another month

before he ran out of time
to make his quota of seals.

But, this year, his world is shrinking early.

He 's got no choice.

He has to enter a new world

of danger.

Ice Bear is three years old.

Just a teen by polar bear standards.

Now he's got to somehow make it to shore

almost 500 gruelling kilometres away.

He 's done it before, guided by his mother.

Now he 's on his own

and it's going to be one of the longest,
cruelest summers on record.

He 's one of 2, 000 bears
who live in Canada 's Hudson Bay.

Every year, when the ice melts,
some have to head south.

First to islands along their way,

then to the mainland.

Ice Bear and his community live farther south
than any other polar bears on the planet.

For generations, they've been the only group
forced to survive off the ice all summer.

If the world keeps warming,

they won 't be alone.

Polar bears around the world
may also be exiled,

and face the same life-or-death struggle.

All across Hudson Bay,

marine mammals are looking
for summer homes.

Walruses, a tempting source of fat.

Ice Bear can pick up a scent
almost a kilometre away.

This may be his one chance to make up

for that seal he missed before the ice melted.

The walrus' nose is keen, too.

The mothers' guards go up.

Ice Bear is taking on a creature
who 's adept in the water.

A ton of tusk and trouble.

It is a remarkable encounter.

A scene rarely witnessed.

Being on his own for the first time
is harrowing.

One in five adolescent bears die.

For cubs to survive, their mother's lessons
have to last them a lifetime.

Cub boy, cub girl,

neither's got much fat
for energy and insulation.

They keep close to Mum,
mimicking her every move.

For the first two years of her cubs' life,
they're completely dependent on her.

They're still nursing.

She needs to find herself food,
or her cubs won 't last.

This desolate slab is just a pit stop.

Though its scent

is now forever ingrained
in her cubs' memory.

That's what's keeping Ice Bear going now.

His memory has led him to the same islands.

The scent he's picked up?
Thick-billed murres.

The division between sky and sea
is lost on them.

This time of year, the plankton bloom
draws herring and shrimp,

a feast for murres.

The bear smells a meal, too.

But there 's 200 metres between him and it.

It's a challenge
no sensible adult bear would go for.

Leave it to a desperate teen.

The murres pick cliffs for their colonies
to keep predators from approaching.

The ledges are just enough purchase.

Nobody expects a cliff-climbing polar bear.

This is behaviour
never before captured on video.

The question is, for all the risk and work,
is it worth it?

Not for one chick.

Bones and feathers are a recipe
for starvation.

Ice Bear needs fat.

His only hope is still 250 kilometres away.

He 's got to make it to the mainland.

There are no landmarks to guide him.

Incredibly, he can orient. By day, to the sun.

By night, the stars are his compass.

He may actually use them
to track his course ahead.

Night after night,
Ice Bear doesn't sleep or eat.

After 1 0 days,

land.

But then polar bears are built to last on ice,
not land.

For Ice Bear, survival might be a long shot.

Ice Bear actually evolved from a land bear,
like the grizzly.

Now he 's forced to revisit his roots,
and adapt.

He 's not equipped to hunt this strange prey.

Animals of the earth, not the ice.

And he's not designed for the heat.

It's 28 degrees Celsius.

Misery.

At least the bugs get to eat.

There's no way to get comfortable.

Another older male has been here
long enough to know.

Get wet.

Ice Bear has got to learn the ropes.

That's one thing he's got going for him.
Polar bears are eager students.

One life lesson he needs now
is how to keep from starving.

In fact, scarfing down snacks is a mistake.

The veteran knows that eating
would throw off the altered state he 's in.

To get his metabolism to slow down,
the older male is fasting the whole summer.

It's a zombie-like state
called "walking hibernation. "

He'll live off his fat reserves
and spend his waking hours half-awake.

But the ice bear can 't swing it.

He 's too young to make
the metabolic change.

He can last the length of a typical summer
before starvation sets in.

The problem is summer has gotten longer.

This female is already at death 's door.

She didn't eat enough seals
before the ice broke up.

Drinking is a sign of desperation.

If she were healthy, she 'd get hydrated
by metabolising her own fat.

But she has no fat.

It's a cruel fate.

To come so far
just to suffer on a distant shore.

(INSECTS BUZZING)

Not all Hudson Bay bears
put their trust in the land.

It's August, and a straggler is still adrift.

He's got a strategy to stay here
the whole season long.

He 's learned to hunt along the way

and take on a walrus.

In the water,
the straggler is no match for a walrus.

But, eventually,

the herd needs to rest.

The perfect opportunity for an ambush.

They've been out on a four-day binge,
foraging for clams.

Now they're exhausted.

One catch, and the straggler

will have enough to last him for days.

A calf's body is one-third fat.

But the young are all surrounded by adults.

Big, dangerous animals.

While they're restless, their guard is up.

There 's no such thing as one itchy walrus.

The herd that moults together,
itches together.

Finally.

Most bears wouldn't risk it.

The hungry straggler isn't thinking twice.

The straggler approaches downwind
to avoid detection.

A mother's instinct to care for her young
is a powerful drive.

There 's only one that can be stronger.

Hunger.

The straggler will follow the herd all summer,
picking off calves with ease.

He won 't need to bother
migrating to land this year.

Some castaways aren't so lucky.

Here, far from where the bears belong,
death is a fact of life.

He may have died from an injury.

Or from swimming those
hundreds of kilometres to get here.

But his misfortune may be
the starving female 's salvation.

Cannibalism is rare among polar bears.

Being forced to live on land
changes everything.

On the ice, she 's a noble hunter.

Now she 's reduced to scavenging
the flesh of her own kind.

In 1 6 years,
the Western Hudson Bay polar bears

have dwindled by a staggering 22%.

This female

probably won 't survive the season.

For mother and cubs,
the journey is finally over.

But the odyssey has taken a toll on her.

Through the long journey here,
she 's had to nurse them.

While adult males withdraw
into walking hibernation,

her cubs depend on her being awake.

The demands of nursing can be dire.

Somehow, she 's got to find food.

The ice bear seizes an opportunity,

takes the mother's cue,

and follows her.

She 's guided by memory

of an exhausting three-day walk to a cove
where she 's found food before.

Here, beluga whales rub against the rocks
and moult their skin.

When the tide goes out, a few get beached.

Mother and cubs feed first.

Cub boy and cub girl are
beginning to get weaned,

and what better inducement?

Ice Bear knows to give the family wide berth.

Some scraps tide him over

and, rather than fight,
he's learned to conserve his energy.

And to be patient,
though he's on the verge of starvation.

For Ice Bear, after weeks of waiting,
it's time to eat.

Mum isn't yet free of her burden to nurse.

And now she 's got another problem.

The ice bear is going to
follow her everywhere.

For him, that could make the difference
between life and death.

September.

With the fall, animals are on the move.

But one is settling in for the long haul.

By now, every polar bear
that's coming ashore has arrived.

On the ice, they would've led lives apart.

Polar bears in the high north
seldom cross paths.

The Hudson Bay bears are different.

This time of year, they're forced
into a narrow corridor of shoreline.

They socialise.

And Ice Bear gets to learn all the more.

Males fight to win a mate.
These two are just sparring for practice.

For the cubs, it's a spectator sport.

Being social has its advantages.

The more practice you get,

the better your chances
when it's time for the real fight.

Though, when they feel crowded,

big males are known to attack cubs.

Nursing keeps Mother's young
from wandering off and getting into trouble.

Unless trouble follows them.

Ice Bear has been tailing the mother
for weeks.

Challenging him to leave would take energy.

But so does corralling her cubs.

Then, a milestone.

Boy cub draws away.

Independence is a rite of passage.

But Ice Bear may turn aggressive.

Mother levels a warning.

But boy cub has tasted
something irresistible.

It's a costly game of cat and mouse.

The calories the cubs are burning
come from Mum 's milk.

This has got to stop.

Some teenagers are a bad influence.
This one is worse.

A distraction that's blinded Mum
to a deadly visitor.

A wolf.

Where there 's one wolf,
there could be a pack.

Ice Bear is on his own.

They're lucky the wolf is as well.

But, in the confusion,
Ice Bear loses track of the others,

his lifeline to food and family.

Mother's journey isn't over.

Here, on the coast,
they're exposed to threats.

Perhaps there'll be safety
in the cover of the forest.

Their exile is taking them deeper still
into a world even stranger to them.

Nobody knows much about the time

mothers and cubs spend
hidden in the woods.

That is about to change.

These aren't hunters. They're biologists.

And their ammo is just a tranquiliser.

They believe the Hudson Bay bears

could be a bellwether for the entire species,
pioneers of the warming world.

These bears spend so much time
on land already.

If they can 't adapt to the longer summers,
other populations don 't stand a chance.

They fit Mum with a video camera.

As she wakes up,
a unique home movie begins rolling.

In two weeks, the camera will pop off

and the researchers can
get their first glimpse

from a polar bear's point of view.

It offers a remarkable revelation.

The bears have a sweet tooth for berries.

It makes no sense.

Berries have no fat,
no apparent nutritional value for them.

And foraging takes a lot of energy.

Maybe it's a throwback.

Terrestrial bears, like grizzlies,
are big on berries.

Living on land may be driving the polar bears
to revert to their evolutionary roots.

A desperate strategy.

November.

Just a generation ago, Hudson Bay
would have been frozen by now.

Ice Bear's first summer alone should be over,

but he 's trapped on land in limbo.

Following his instincts, he heads northwest,

where the sea freezes earliest.

The snow along his way is just a tease.

He's not alone.

By this point in the season,

sparring partners have squared off
many times in mock battles.

They've come to know who's their measure,

who 's a menace,

and when it's time to walk away.

If Ice Bear is going to someday
compete for a mate,

he 's got to find someone his own size
to spar with.

He 's searched for food, for haven,
for company,

in vain.

Now the season delivers the ultimate insult.

The route he follows was blazed
thousands of years ago.

Before tourists,

before cameras,

before the summer got so damned long.

He 's curious, too.

He gets to visit the human zoo.

Business is booming.

The tourist season lasts longer than ever,

since the bears are stuck here
an extra month.

Polar bears are crossing paths
with our world more and more.

The encounter can get ugly.

Dogs, like wolves,

are ancient enemies of bears.

But, this time, it's the pack that's at risk.

The bear that's approaching
could not be more hungry.

The ice bear could easily kill a dog.

Instead, an extraordinary turn.

That a bear wants companionship with dogs

is a strange sign of the times.

No less bizarre than that
he would need to wait for winter,

so long overdue.

For the ice bear,
company may be a consolation,

but it's not the answer.

The ice is finally beginning to beckon.

Come December, the waters roil.

On the banks of Hudson Bay,
the weary gather.

The ice bear has finally found his way
to others his age.

If they're going to compete for females,
they have to learn to spar

and this is their last fleeting chance.

A chance Ice Bear now seizes.

A bond and rivalry forged on land

may last them years on the ice.

Finally, the sea turns from black to white.

He 's survived one of the
longest summers on record.

Nearly six months on land.

His homecoming is a bay
once again entombed.

Next year,
the summer may be longer than ever.

The time to hunt seals on ice
may get even shorter.

But, for now, the ice bear is home.
