Narrator: The tip of Patagonia stretches

into the great Southern Ocean,

where giants roam.

Whale trills, squeaks

In the deep, all is quiet.

But above, a storm is raging.

Monje speaking Spanish

Narrator: At these latitudes, the sea can be terrifying.

They say that below 40 degrees south,

there is no law,

but below 50, there is no god.

At the ends of the Earth is a land of extremes...

...nome to spectacular wildlife.

For centuries,

people and animals have battled for supremacy.

But now enemies are becoming allies.

Together they face new challenges...

...Iin our rapidly changing world.

You are at the mercy of the elements.

Narrator: This is the story

of what it takes to survive...

...on the edge of the world.

Patagonia's far south is dominated by the wind...

WIind whistling

...and the cold.

Extending below the 50th parallel,

no other land mass lies so close to Antarctica.

To survive here I GCERE= el

Birds squawking

...determination,

and sometimes sheer size.

Much of the land is just empty, wind-blasted tundra.

But the sea is teeming with life.

A humpback whale.

Whale calls

This 30-ton giant has traveled all the way

from its winter breeding grounds in the tropical Pacific,

a journey of more than 4,000 miles.

On its tail is wildlife veterinarian Frederick Toro.

Toro speaking Spanish

These are the waters of the Francisco Coloane Marine Park

in the Straits of Magellan.

lalicier marine biologists realized

this is an important feeding ground for humpbacks.

Birds squawking

The forceful mixing of the Atlantic and Pacific oceans

stirs up nutrients, creating plankton blooms,

the foundation of the marine food chain.

Food is so plentiful,

the whales behave in extraordinary ways.

Toro speaking Spanish

Wow.

But the whales aren't the only ones plying these waters.

Foghorn

Toro speaking Spanish

The steady stream of ships through the Straits

might drive away the whales entirely.

Toro speaking Spanish

Foghorn

To make his case, Frederick needs proof

that the whales are stressed —

and that means taking a sample.

But chasing whales in boats may panic them.

So Frederick and his team are trying something new.

A drone.

Its mission?

To hover over the whale's spout

and catch a sample of its snot.

Drone whirring

Spout samples reveal levels of stress hormones

as well as pollution.

But catching a sample is easier said than done.

The timing has to be just right.

Missed.

The whale disappears.

Flying against the wind,

the drone's battery is running out of juice.

Drone whirring, beeping

If the whale doesn't 10 gizTol=R:1eeal

they'll have to give up.

One last chance.

Got it.

Toro speaking Spanish

Frederick hopes that his sample will provide the proof

that these humpbacks need protection.

The rich waters of Patagonia's far south

have the power of life...

...and death.

Narrator: Crab fisherman Fernando Monje

has worked the waters of the Beagle Channel

for over a decade.

The 130-mile seaway runs east-west across Patagonia.

The narrow channel funnels

the Southern Ocean's ferocious winds.

Speaking Spanish

Birds squawking

NF-Tag= o g Some ships don't make it.

The waters of the far south

have claimed well over 1,000 ships...

...and more than 10,000 sailors.

At first, Fernando saw these wrecks

as nothing more than rusting monuments.

But then he decided to take a closer look.

Fernando speaking Spanish

Nature has claimed this steel hulk.

Thanks to the nutrients stirred up by the storms,

these waters are full of life.

But free-diving here is risky.

You can easily get disoriented...

...even trapped.

Fernando speaking Spanish

Narrator: Luckily, today's conditions are good.

Fernando gets out safely with his haul.

He makes a good living from the shellfish he collects here.

Fernando speaking Spanish

Narrator: Further up the coast, another underwater forager

is also returning home.

Penguins honking

A mother gentoo penguin bringing food to her baby.

She's back on Hammer Island after a 10-hour fishing trip.

She swam nearly 13 miles,

diving down 200 feet or more to feed.

Now she hikes through hoards of her cousins ——

Magellanic penguins.

Penguins trilling, honking

Exhausted,

but home at last.

Finally, a chance to rest.

Or maybe not.

Her 6-week-old chick is ravenous.

Chick chirping

Growing fast, he has an insatiable appetite.

Mom needs to keep some food back for herself,

but her chick won't take "no" for an answer.

Sometimes it's not easy being a mom.

And raising a family here is especially hard.

One moment, you're basking in the sunshine.

The next, you're being stalked by an outsider.

Narrator: On Hammer Island, deep in the far south,

gentoo penguins face a harsh and remote existence.

But they're not alone.

This is marine biologist Dr. Andrea Raya Rey.

Speaking Spanish

Narrator: Andrea and her team don't just observe the penguins.

They get hands-on.

Dramatic music plays

Penguins chirping

They take blood samples and give the birds a health check.

Andrea speaking Spanish

Narrator: Studying them on land is one thing.

But what happens when the gentoos go to sea?

Andrea wants to learn how they feed.

A small camera is attached to this male's back

to document his hunting strategy.

Ungainly on land,

the gentoo is the world's fastest underwater bird.

His wings propel him at over 20 miles per hour

into a shoal of small fish.

But he's not the only one feasting here.

Seabirds dive in from above, grabbing what they can.

Gentoos were thought to primarily feed at depth,

but now Andrea has discovered

that they're also opportunistic feeders.

Right now, there are only 50 pairs

o lie=Ta 100l living on Hammer Island.

But the colony is growing.

Fish are plentiful in the open water,

and nearby is a habitat that supports yet more food.

Penguins honking

A giant kelp forest.

Like an underwater rainforest,

it's one of the most biodiverse habitats in the ocean,

providing food and shelter for hundreds of species.

The conditions here are perfect.

These are the largest, most pristine kelp beds in the world.

The fjords and seaways of the far south stretch

for thousands of miles.

Remote and rarely visited by humans.

Seal purring

In 2003, scientists made a surprising discovery

here in the heart of the Tierra del Fuego archipelago.

On this small island, they found an animal

that was completely unexpected.

One of the largest birds to take to the skies...

Bird squawks

...albatross.

These giants normally nest on remote oceanic islands,

not in narrow fjords surrounded by mountains.

No-one knows why these black-browed albatross

have chosen to settle here.

Exposed and steep,

it's a challenging place to build a nest.

But every spring,

60 pairs return to their small dirt mounds.

Albatross squawking

Black-browed albatross can live over 70 years.

This couple may well have been together for decades.

They only produce a single precious egg every year or two.

The female could be away for days, even weeks.

And there's a chance she may not come back at all...

...because out at sea, there is something deadly.

Narrator: This black-browed albatross father

is keeping his precious egg warm.

And he needs to sit tight.

a snowstorm is coming.

Wind whipping

When the wind is this bitterly cold,

leaving the egg for a moment might Kkill it.

And in the far south, it can blow for days.

And days.

Albatross squawking

It's been a week since his partner left.

Cold and hungry, soon he will have no choice

but to abandon his egg and feed.

Finally, his partner returns.

For now, their egg is safe.

And dad is free to search for his own food.

Time to head for the open ocean.

His wings, nearly 8 feet across,

allow him to glide with almost no effort.

He may travel hundreds of miles on a single feeding trip.

Riding the winds, he soars with barely a wing flap.

But there's danger in the feeding grounds.

Hooks — often lethal for albatross.

Commercial fishing vessels trail hundreds of them on lines

that can be over a mile long.

Every year, thousands of albatross are hooked and drown.

This longline fishing boat is different.

And not just because it's smaller,

but because of its skipper —— Juan Carrasco.

Speaking Spanish

Narrator: On a heavily weighted line,

Juan's bait quickly sinks beyond the reach of the albatross.

Speaking Spanish

This one may be hungry,

but at least he's safe.

Juan speaking Spanish

Narrator: Sometimes gatherings of albatross

even guide Juan to good fishing spots.

Albatross squawking

And in return, he gives them nutritious cast-offs

from his catch.

But perhaps the most incredible part of this story

is how widely Juan's technique is spreading.

Prompted by scientists,

the Chilean commercial longline fleet

is now using Juan's heavy-weighted bait technique.

Hook-related deaths in Patagonia

have dropped to practically zero.

It's an extraordinary conservation success story.

Juan's technique has even been adopted by other fleets

across the rest of the Southern Ocean.

Juan speaking Spanish

Narrator: While the rich waters of Patagonia's far south support

an amazing diversity of sea life...

...the land appears desolate.

Much of it is a treeless steppe.

Only the very toughest animals can survive here.

Narrator: Isla Grande,

the largest land mass of Tierra del Fuego,

covers 18,000 square miles.

This is the last land before Antarctica ——

the very end of the world.

It takes a tough customer to survive here.

Sheep bleating

Europeans introduced sheep around 150 years ago

for wool and meat.

In summer, they graze on the hills.

But winter is coming.

Freezing rain is forecast.

Shepherd Cristian Trina must get his sheep down

to his lowland ranch.

All 1,200 of them.

Cristian speaking Spanish

Narrator: If they get cold and wet,

many could die from pneumonia.

To get to the lower pastures, they must cover

more than 10 miles before nightfall.

Moving so many sheep is a tough job,

but Cristian has some expert helpers.

It's not an easy life, but Cristian loves it.

Cristian speaking Spanish

But times are changing.

Fewer young people are choosing this way of life.

Horn honks in distance

And the modern world is taking over.

A highway now runs alongside the old traditional trail

Cristian uses for his sheep.

Cristian speaking Spanish

Finally, the flock can move away from the road.

Their 10-mile journey is almost at an end.

The weather has held,

and home is in sight.

Cristian speaking Spanish

Narrator: And just a few miles south from here, a remarkable animal

is making a surprising comeback to Patagonia.

The king penguin.

Penguins chirping

These are the only king penguins on the South American land mass.

Once, hundreds of thousands of them

lived on Tierra del Fuego.

Penguins honking

But they were hunted to extinction by European settlers.

It was only in 2010, unexpectedly,

a handful of king penguins returned.

But the land's owner, Cecilia Duran,

was not the first person to find them.

Cecilia speaking Spanish

Narrator: Since that moment, she has dedicated her life

to looking after these penguins.

Cecilia speaking Spanish

Narrator: To keep them safe, Cecilia has built an enclosure

around the penguins' breeding grounds.

Narrator: Visitors are kept at a safe distance.

Ticket sales fund research and conservation.

Cecilia is so devoted to protecting them,

she is known locally as "the mother of penguins.

Cecilia speaking Spanish

The colony may be small, but it's growing every year

under the vigilance of its passionate protector.

King penguins are under increasing threat

from climate change and over-fishing.

So their unexpected return to Tierra del Fuego

is something to be celebrated.

But where prey goes,

predators follow.

And a fearsome penguin hunter has arrived in Patagonia.

Narrator: The San Rafael glacier.

Located in southern Chile,

hundreds of miles north of the king penguin colony,

it empties into an almost landlocked lagoon.

Because of the steepness of this glacier and climate change,

a lot of ice falls here.

On average,

a volume twice the size of the Empire State Building

crashes into the lagoon every day.

And the fractured ice flows hide a formidable predator...

...a leopard seal.

Normally, they live and breed

almost exclusively in the Antarctic...

...where penguins are one of their main prey.

But in the San Rafael lagoon,

more than 1,200 miles from Antarctica,

there are no penguins,

and it's a mystery how these seals are surviving here.

On a mission to learn more about them

is national park ranger Nicolas Fernandez.

Nicolas speaking Spanish

Narrator: Although Nicolas doesn't yet have the funds

to analyze the seals' diet,

he thinks he knows what they're eating.

Large numbers of Patagonian rock cod

live just below the glacier wall.

Speaking Spanish

Whenever there's an icefall,

the leopard seals swim directly for it.

Nicolas suspects the leopard seals

are hunting fish scattered by the impact.

But his biggest discovery has come from his observation

of this particular seal.

Narrator: Nicolas has proved this is the most northerly

established breeding population of leopard seals on the planet.

In a world where so many large predators are disappearing,

the arrival of this incredible hunter

into new territory is remarkable.

Nicolas speaking Spanish

Narrator: Here in Patagonia's far south,

life is making a comeback,

returning home to habitats once abandoned.

Growing in number.

And even expanding into new areas.

LGl TR great challenges ahead.

But the people here love this place

and the life it sustains.

With such passion and commitment,

anything is possible.
