NARRATOR: WHEN YOU SEE THIS
SYMBOL, YOU KNOW YOU’RE WATCHING

TELEVISION THAT IS EDUCATIONAL
AND INFORMATIONAL.

THE MORE YOU KNOW ON NBC.

DYLAN: HI, EVERYBODY, I'M DYLAN
DREYER, AND WE'RE ABOUT TO

VENTURE INTO THE WONDERFUL WILDS
OF OUR PLANET HERE ON "EARTH

ODYSSEY".

TODAY, WE'RE OUT TO SEE SOME
CURIOUSLY CRAFTY NORTHERN

NATIVES THAT THRIVE ABOVE THE
EQUATOR, LIKE THESE

OUT-OF-TOWNERS THAT HAVE FOUND A
FOREVER HOME IN FRANCE AND A

TRIO OF CARNIVORE CUBS EAGER FOR
THEIR DINNER DELIVERY.

LATER, WE'LL SNEAK A LOOK AT ONE
OF THE BIGGEST BEARS ON THE

PLANET.

BUT FIRST, WE HEAD FOR THE HIGH
MOUNTAINS WHERE A MINI MAMMAL IS

HARD AT WORK PREPARING FOR
WINTER.

WE'VE GOT A WHOLE LOT IN STORE
FOR YOU HERE ON "EARTH ODYSSEY".

[MUSIC]

DYLAN: ONE OF OUR PLANET'S MOST
DRAMATIC COLLECTIONS OF

BEAUTIFUL LANDSCAPES IS
UNDOUBTEDLY THE CANADIAN

PROVINCE OF BRITISH COLUMBIA.

ITS BRIGHT FORESTS AND
STAGGERING MOUNTAINS GIVE A

SENSE OF WONDER TO THIS UNTAMED
WILD.

SUCH EXPANSIVE WILDERNESS MEANS
THAT ANIMALS OF ALL KINDS CAN

THRIVE HERE.

ON PEAKS OR IN VALLEYS, WHETHER
FLORA OR FAUNA, IN THIS REGION,

THE BEAUTY OF NATURE IS ON FULL
DISPLAY.

FEW NATURAL FEATURES HAVE THE
IMPACT AND AWE OF MOUNTAIN

RANGES.

THESE NATURAL SKYSCRAPERS FORMED
BY THE MEETING OF TECTONIC

PLATES DOMINATE THE HORIZON IN
THIS PART OF THE CANADIAN

WILDERNESS.

MANY OF THESE PEAKS REACH WELL
OVER 10,000 FEET AND PRESENT

EXTREMELY DIFFICULT LIVING
CONDITIONS FOR BOTH PLANTS AND

ANIMALS.

BUT THERE ARE THOSE THAT HAVE
FOUND A WAY TO THRIVE IN THIS

HIGH-ALTITUDE HOME.

RIGHT ON CUE.

THIS IS A HOARY MARMOT...

...PERFECTLY AT EASE IN THIS
RUGGED, ROCKY ENVIRONMENT.

THEIR SLOW METABOLISM, WHICH
ALLOWS THEM TO CONSERVE ENERGY,

REQUIRES THAT THEY BASK IN THE
SUN EACH MORNING TO PERK UP AND

ACCUMULATE HEAT.

MARMOTS FORM CLOSE-KNIT FAMILY
CLANS AND HAVE A RATHER PECULIAR

WAY OF GREETING EACH OTHER.

THEY SNIFF EACH OTHER'S CHEEKS
IN ORDER TO RECOGNIZE EACH

OTHER'S SCENT.

IT'S ODOR ID.

[MARMOT WHISTLING]

AN ALARM.

THE WHISTLING OF A NEIGHBOR IS
HEARD ACROSS THE ROCKS.

[WHISTLING CONTINUES]

WEIGHING ONLY FIVE OUNCES AND
MEASURING LESS THAN EIGHT INCHES

FROM NOSE TO TAIL, THIS IS THE
AMERICAN PIKA.

IT'S ONE OF THE RARE MAMMALS
THAT MANAGES TO LIVE AT THIS

ALTITUDE THROUGH EVERY SEASON.

UNLIKE MARMOTS, WHO HIBERNATE IN
THE WINTER, THE PIKA STAYS

ACTIVE ALL YEAR ROUND.

NOW THAT'S MASTER OF THE
MOUNTAIN.

PIKAS LIVE ABOVE THE TREE LINE
AT ABOUT 8,000 FEET IN THE COLD

AND WINDY ALPINE ZONE.

HERE, NOTHING GROWS BUT GRASSES,
WHICH SUITS THIS LITTLE

MOUNTAIN-DWELLER JUST FINE.

WITH A STRICT VEGETARIAN DIET,
THESE ALPINE GRASSLANDS PROVIDE

AN ABUNDANCE OF NOURISHMENT FOR
THE PIKA.

WHILE OTHER ANIMALS REDUCE THEIR
BIOLOGICAL ENERGY LEVELS TO

SURVIVE THE HARSH WINTERS, THE
PIKA CONFRONTS THE COLD HEAD-ON.

ITS SMALL ROUND SHAPE IS IDEAL
FOR CONSERVING BODY HEAT, AND

THOSE FURRY FEET ACT LIKE
SNOWSHOES SO IT CAN MOVE EASILY

ACROSS THE SNOW.

LIFE SEEMS IDYLLIC FOR THIS
MINI-MAMMAL, BUT THERE'S ALWAYS

A CATCH.

FINDING FOOD IN THE WINTER
MONTHS CAN PROVIDE DIFFICULT AS

THE GRASSES ARE HEAVY SNOWFALL,
BUT THIS LITTLE ROCK RABBIT HAS

GOT THE ANSWER.

AT THE END OF SUMMER, THEY START
HAYMAKING.

QUICK...

...AGILE...

...AND EFFECTIVE...

...ABLE TO GATHER AND STORE FOOD
WITH INCREDIBLE EFFICIENCY.

[PIKA WHISTLING]

EVEN THE MARMOTS LOOKING ON
CAN'T HELP BUT BE IMPRESSED.

DASHING ACROSS THE GRASSLAND,
THE PIKA RARELY TAKES A BREAK

FROM ITS MISSION TO GATHER FOOD.

THE ONLY STOPS IT MAKES ARE TO
QUICKLY SURVEY THE SURROUNDING

AREA FOR ANY PESKY PREDATORS.

ONE CAN NEVER BE TOO CAREFUL.

[PIKA WHISTLING]

AFTER GETTING THE ALL CLEAR,
THEY CAN DASH BACK TO A

STOREHOUSE, WHERE THEIR BOUNTY
IS KEPT SAFE.

IT WON'T BE LONG BEFORE THEY'RE
BACK OUT AGAIN, BECAUSE IN SUCH

A HARSH ENVIRONMENT, THE WORK IS
NEVER DONE.

AFTER THE BREAK, MEET A
SERIOUSLY BIG RODENT WITH AN

EVEN BIGGER REPUTATION.

LATER, WE'LL SEE WHAT'S GOT
THESE CUTE CANINE KITS OUT OF

BED SO EARLY.

AND IT'S BEST TO STEER CLEAR OF
THIS FEROCIOUS FORAGER WHEN

THEY'RE ON THE PROWL.

[PIKA WHISTLING]

STAY TUNED FOR MORE "EARTH
ODYSSEY".

.

NARRATOR: WE NOW RETURN TO THE
MORE YOU KNOW ON NBC.

DYLAN: HIDDEN AMONGST THE LUSH
RIVER VALLEYS OF FRANCE, A

SURPRISING CHARACTER IS WAITING
TO BE DISCOVERED.

THIS IS A COYPU.

IT MAY LOOK LIKE A BEAVER,
BUT IT IS A COUSIN FROM

SOUTH AMERICA.

THIS PARTICULAR SPECIES IS FAR
FROM ENDANGERED.

IT HAS FOUND THE RICH VEGETATION
OF THE LOIRE MARSHES TO BE THE

PERFECT PLACE TO PROSPER.

THIS FAMILY'S YOUNG WERE BORN
THREE WEEKS AGO AND ARE JUST

BEGINNING TO LEAVE THE BURROW.

CLOSER TO THE OCEAN, THE LOIRE
ESTUARY TURNS INTO AN AMAZING

MOSAIC OF NATURE AND INDUSTRIAL
ZONES.

THIS CONCEALS AN ENVIRONMENT
RICHER THAN ONE WOULD THINK.

VAST QUANTITIES OF SAND WERE
SHIFTED WHEN THE LOIRE WAS

DREDGED TO BUILD THE PORT OF
NANTES.

THE SAND WHICH WAS DEPOSITED
ALONG THE BANKS FORMED NEW

MEADOWS WHICH ARE TEEMING WITH
LIFE.

NEAR A SMALL POND, THIS MALE
ADDER IS SOAKING UP THE LAST FEW

RAYS OF SUNSHINE.

HE ABSORBS AS MUCH HEAT AS HE
CAN BEFORE LEAVING AT NIGHTFALL

TO CATCH THE MEADOW'S SMALL
MAMMALS.

THIS FOX HAS RECENTLY BECOME
INDEPENDENT.

HE IS STILL TOO YOUNG TO BE AN
ACCOMPLISHED HUNTER.

IDEALLY, HE'S ON THE LOOKOUT FOR
A PARTICULARLY CARELESS RABBIT.

RABBITS ARE PERMANENTLY ON
HIGH-ALERT, AND THEIR 360-DEGREE

FIELD OF VISION ALLOWS THEM TO
SEE ALL AROUND AND ABOVE THEM.

THEIR LARGE EARS ARE SENSITIVE
TO THE SLIGHTEST SOUND, SO THE

YOUNG FOX WILL FIND IT DIFFICULT
TO SNEAK UP ON THEM.

EVEN AMONG THESE LUSH RIVERBANKS
WITH SUCH A DIVERSE POPULATION

OF PLANTS AND ANIMALS, THERE'S
NO SUCH THING AS A FREE LUNCH.

WHEN WE COME BACK, THE MISTY
MOUNTAINS MAKE FOR A PERFECT PUP

PLAYGROUND.

AND WE'LL MEET THE BEAR BEHIND
ONE OF NORTH AMERICA'S BIGGEST

APPETITES.

[BEARS GROWLING]

ALL THIS NEXT ON "EARTH
ODYSSEY".

.

NARRATOR: WE NOW RETURN TO THE
MORE YOU KNOW ON NBC.

DYLAN: WHEN LOOKING AT ALL THE
DIFFERENT ENVIRONMENTS ACROSS

EUROPE, ONE STANDS OUT AS A TRUE
HUB OF WILDLIFE ACTIVITY IN THE

WEST, THE LOIRE VALLEY.

MORE THAN 50 PERCENT OF THE
ANIMAL SPECIES IN FRANCE CAN BE

FOUND IN THIS LUSH RIVER-RUN
REGION THAT STRETCHES MORE THAN

625 MILES.

THIS BUSY WATERWAY SEES
THOUSANDS OF ANIMALS VYING FOR

THE BEST FEEDING GROUNDS,
NESTING SITES, AND OF COURSE, A

PLACE TO START A FAMILY.

AND FOR ONE SPECIES OF MAMMAL,
THERE'S NO BETTER REAL ESTATE

THAN WHERE THE RIVER ITSELF
BEGINS.

TAKE A LOOK.

MOUNT GERBIER DE JONC IN
THE ARDECHE, THIS IS WHERE

THE LOIRE HAS ITS SOURCE.

EVEN IN THIS EARLY SPRING, THE
CLIMATE IS STILL UNUSUALLY

HARSH, AS IF THIS WERE THE HIGH
MOUNTAINS.

LITTLE DROPS OF SNOW MELT TO
BECOME A THIN STREAM OF WATER

WHICH WILL GRADUALLY SWELL TO
BECOME A MIGHTY RIVER, THE LAST

GREAT UNTAMED WATERCOURSE IN
EUROPE.

THE SOURCE OF THE LOIRE IS STILL
HIDDEN WITHIN A DENSE FOG FROM

WHICH EMERGE THREE FOX CUBS.

THEY WERE BORN HERE JUST SEVEN
WEEKS AGO AND ARE JUST STARTING

TO LEAVE THEIR DEN.

WHILE THEY ARE YOUNG, FOXES LIVE
IN SMALL FAMILY GROUPS KNOWN AS

SKULKS; HOWEVER, THE
TOGETHERNESS DOESN'T LAST LONG.

FOXES ARE MOSTLY SOLITARY
ANIMALS, HUNTING AND SLEEPING

ALONE AT JUST SEVEN MONTHS OLD.

BUT FOR NOW, IN THE VAST AND
BEAUTIFUL GREENERY OF THE LOIRE,

THESE CUBS ARE STICKING
TOGETHER.

[FOXES GROWLING]

THEIR FATHER SETS OFF HUNTING A
FEW MILES AWAY.

HE HAS FOUND A MEADOW WHICH HAS
RECENTLY BEEN MOWN, AND THERE IS

NO LONGER ANY GRASS FOR VOLES TO
SHELTER IN.

FOXES PROTECT CROPS FROM RODENTS
AND CAN CATCH MORE THAN 40 OF

THEM IN A DAY.

THE FATHER ONLY NEEDS 15 OR SO
VOLES TO SUSTAIN HIMSELF, BUT

BRINGS BACK MANY MORE FOR HIS
FAMILY.

THE CUBS ARE STILL SUCKLING
THEIR MOTHER, BUT ARE ALSO

STARTING TO EAT SMALL RODENTS.

THE MOTHER STAYS CLOSE TO THE
DEN TO KEEP AN EYE ON HER YOUNG.

THESE FOXES ARE IN FACT
SQUATTERS.

THEY HAVE FOUND A WAY TO AVOID
HAVING TO DIG UP THIS HARD AND

ROCKY SOIL BY RELYING ON AN
EXCELLENT SET OF ALLIES...

...MARMOTS.

THEY HAVE TURNED THE SOIL AROUND
THE SOURCE OF THE LOIRE INTO A

VERITABLE SWISS CHEESE, AND THE
FOXES RECYCLE THEIR ABANDONED

DENS.

IN THE SPRING, THE MARMOTS
EMERGE FROM A SIX-MONTH PERIOD

OF HIBERNATION.

THEY HAVE LOST UP TO HALF THEIR
BODYWEIGHT.

THE MEADOWS OFFER THE PERFECT
PANTRY FROM WHICH TO REPLENISH

THEIR RESERVES OF BODYFAT.

HERE AT ITS SOURCE, THE LOIRE IS
FAR FROM THE MIGHTY RIVER IT

WILL BECOME LATER.

IT IS EVERYWHERE AND NOWHERE, A
NETWORK OF TINY WATERCOURSES

WHICH ARE HOME TO SOME
REMARKABLE SPECIES.

THIS MALE ALPINE NEWT IS SHOWING
OFF HIS FINEST COLORS.

IT'S THE MATING SEASON, AND HE'S
LOOKING FOR A FEMALE.

THESE RAPID TAIL MOVEMENTS ARE
PART OF HIS SEDUCTION STRATEGY,

A SECRET WEAPON.

THIS IS HOW HE WILL SEND OVER
HIS PHEROMONES, BUT IT'S GOING

TO TAKE MORE THAN A CASUAL WAVE
OF THE TAIL TO ATTRACT THIS

AMOROUS AMPHIBIAN.

COMING UP, A MASSIVE MAMMAL
MIGRATOR IS ON THE HUNT IN THE

HIGH MOUNTAINS.

THIS AND MORE WHEN "EARTH
ODYSSEY" RETURNS.

.

NARRATOR: WE NOW RETURN TO THE
MORE YOU KNOW ON NBC.

[MARMOT WHISTLING]

DYLAN: A WARNING SIGNAL RINGS
ACROSS THE MOUNTAINS.

IT'S AN ALARM BELL FOR ANY
ANIMAL NEARBY, AND THE MESSAGE

IS CLEAR, RUN.

AN UNFAMILIAR FACE IS COMING
THIS WAY.

GRIZZLY BEARS ARE COMING FROM
THE COAST TO THE ALPINE ZONES.

CAPABLE OF TRAVELING GREAT
DISTANCES, GRIZZLIES CAN MIGRATE

FROM THE HIGH MOUNTAINS TO THE
LOW VALLEYS WHENEVER THEY NEED.

THIS ONE IS MERELY PASSING
THROUGH THE AREA, BUT THAT

DOESN'T MEAN OTHER CREATURES CAN
BE AT EASE.

THERE AREN'T MANY THINGS OR
ANIMALS THAT ARE NOT ON A

GRIZZLY'S MENU.

AS OMNIVORES, THEY EAT PLENTY OF
VEGETATION, FISH, AND MEAT.

FOR NOW, IT LOOKS LIKE THIS BEAR
IS HAPPY TO SEEK OUT ITS MEAL

SOMEWHERE ELSE.

WITH DANGER AVERTED, THE
AMERICAN PIKA GETS STRAIGHT BACK

TO WORK FORAGING.

DESPITE THEIR CUTE AND CUDDLY
APPEARANCE, PIKAS ARE ACTUALLY

ONE OF THE REGION'S TOUGHEST
CHARACTERS.

VERY FEW ANIMALS CAN SURVIVE
LIVING THEIR ENTIRE LIVES IN

ALPINE TERRAIN DUE TO ITS HARSH
CONDITIONS AND EXTREME ALTITUDE,

YET THIS ROCK-RUNNING RABBIT
DOES IT IN STYLE.

THEY WATCH OVER THEIR DOMAIN
WITH FERVENT ATTENTION.

WHILE THEY LIVE IN COLONIES,
THEY DEFEND THEIR TERRITORY

FIERCELY, KNOWING THE DANGERS OF
BEING LEFT WITHOUT SHELTER OR

FOOD STORES WHEN WINTER COMES.

[PIKA WHISTLING]

THESE DRAMATIC LANDSCAPES MAY
PAINT A PICTURE OF BEAUTY, BUT

LIFE HERE CAN BE WROUGHT WITH
CHALLENGES.

[BEARS GROWLING]

EVERY CREATURE BIG AND SMALL
MUST SHOW THEIR RESOURCEFULNESS

AND RESILIENCE TO THRIVE IN THE
REMARKABLE WILDS OF THE NORTHERN

HEMISPHERE.

ACROSS EVERY CONTINENT ON EARTH,
IMPRESSIVE AND BEAUTIFUL

WILDLIFE CAN BE FOUND THRIVING,
EVEN WHERE IT MAY SEEM

IMPOSSIBLE TO DO SO.

AS WE SURVEY AND APPRECIATE OUR
PLANET'S INCREDIBLE CREATURES,

WE ARE GIVEN A GLIMPSE INTO THE
WORLD OF THE WILD AND WHAT IT

TAKES TO SURVIVE THERE.

THANK YOU FOR JOINING US TODAY.

WE HOPE TO SEE YOU FOR ANOTHER
EPISODE OF "EARTH ODYSSEY".
