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 THIS IS "EARTH

ODYSSEY".

TODAY, WE SET OFF TO FIND THE
WILDLIFE THAT THRIVES IN THE

COLDEST REGIONS ON EARTH.

IN THE ALPS, THESE ALPINE
MARMOTS MUST FIGHT TO STAY ALIVE

BEFORE THE SNOW HITS.

THEN, THE FRIGID ALASKAN
WILDERNESS AWAITS THE NEXT

GENERATION OF THIS FAMILY OF
ARCTIC FOX.

AND LATER, WE HEAD TO EUROPE,
WHERE A BIG CAT NEEDS A THICK

COAT TO WEATHER THE CHILLY
CLIMATE.

PLUS, IN MONGOLIA, THESE HORSES
GET THROUGH THE WINTER WITH A

LITTLE HELP FROM THEIR FRIENDS.

ALL OF THIS AND MORE TODAY ON
"EARTH ODYSSEY".

[MUSIC PLAYING]

DYLAN: ABOUT TEN PERCENT OF THE
EARTH'S SURFACE IS COVERED BY

ICE ALL YEAR ROUND, AND THESE
FROZEN AREAS AREN'T JUST FOUND

AT THE NORTH AND SOUTH POLES.

SOME REGIONS CLOSER TO THE
EARTH'S EQUATOR REMAIN ICEBOUND

THANKS TO THEIR INCREDIBLY HIGH
ALTITUDES.

AND AT THESE FRIGID
TEMPERATURES, YOU'LL FIND SOME

OF THE MOST INCREDIBLE AND
RESILIENT ANIMALS IN THE WILD.

LET'S START IN THE ALPS, WHERE
THE GRASS IS GREEN AT THE

MOMENT, BUT WINTER IS RIGHT
AROUND THE CORNER.

IT'S ONLY SEPTEMBER HERE IN THE
ALPS, BUT THE PEAKS ARE SHROUDED

IN WHITE EVEN IN MIDSUMMER.

AND WHILE THESE LOWER SLOPES
MIGHT LOOK IDYLLIC NOW, IN JUST

A FEW MONTHS, THEY, TOO, WILL BE
BURIED IN SNOW.

SO, THE CLOCK IS TICKING FOR
THIS ALPINE MARMOT.

HE'S TOO SMALL TO FACE THE
WINTER ABOVE GROUND, SO HE NEEDS

TO PILE ON THE POUNDS BEFORE THE
COLD SETS IN, WHEN HE'LL RETIRE

TO HIS DEN.

BUT HE'S PICKY ABOUT WHAT HE
EATS, CHOOSING GRASSES WITH THE

HIGHEST LEVELS OF FATS.

HE MUST DOUBLE HIS BODY WEIGHT
IF HE IS TO SURVIVE.

BUT HE'S NOT THE ONLY HUNGRY
ANIMAL UP HERE IN THE MOUNTAINS.

THIS GOLDEN EAGLE IS A MARMOT'S
NUMBER ONE ENEMY AT THIS TIME OF

YEAR...

...SO HIS MISSION WILL HAVE TO
WAIT.

[MARMOT CHIPPING]

THE MARMOT LETS OUT A WARNING
TO THE REST OF THE COLONY.

[CHIPPING CONTINUES]

THEY MUST HEAD FOR SAFETY AND
QUICKLY.

[MARMOTS CHIPPING]

THIS TIME HE ESCAPES UNHARMED.

BUT THERE'S NO TIME TO WASTE.

HE NEEDS TO GET BACK TO WORK.

BEING PREPARED FOR WINTER CAN
MEAN TAKING RISKS.

AS WELL AS EATING, HE NEEDS TO
COLLECT ENOUGH NESTING MATERIAL

TO KEEP HIM WARM.

BUNDLES OF DRY GRASS WILL LINE
HIS BURROW AND ACT AS THE

PERFECT INSULATOR.

AS SOON AS THE WEATHER STARTS TO
TURN, HE HEADS FOR COVER...

...NINE FEET UNDERGROUND, SAFE
IN HIS BURROW.

IT'S TIME FOR HIS BIGGEST TRICK
TO SURVIVING THE COLD, SLEEP.

BUT THIS WILL BE NO ORDINARY
NAP.

FOR THE NEXT EIGHT MONTHS, HE'LL
BE BARELY ALIVE.

AS THE SNOW ARRIVES AND THE AIR
OUTSIDE COOLS, SO DOES THE

MARMOT'S BODY TEMPERATURE...

...DROPPING TO JUST 39 DEGREES.

MARMOTS SHUT DOWN EVERY SYSTEM
IN THEIR TINY BODIES.

IT'S A DRASTIC SURVIVAL
TECHNIQUE, BUT THEY HAVE NO

CHOICE.

THE BIG CHILL IS COMING.

BY PREPARING FOR WINTER'S
ARRIVAL AND SPENDING THE HARDEST

MONTHS UNDERGROUND, THE MARMOT
ENSURES ITS SURVIVAL THROUGH THE

BLEAKEST SEASON.

COMING UP, WE HEAD TO NORTHERN
ALASKA, WHERE THESE FOXES ARE

GETTING READY TO VENTURE OUT
ALONE IN THEIR FIRST WINTER

STORM.

AND LATER, THIS LYNX WILL NEED
MORE THAN A THICK COAT TO STAY

WARM IN ONE OF EUROPE'S COLDEST
REGIONS.

PLUS, THERE'S NO HORSING AROUND
WHEN GETTING READY FOR THE

UNFORGIVING MONGOLIAN WINTER.

.

WE NOW RETURN TO THE MORE YOU
KNOW ON NBC.

DYLAN: WINTER HAS BEGUN TO
TIGHTEN ITS GRIP ON THE ARCTIC

ANIMALS.

BY OCTOBER IN NORTHERN ALASKA,
AVERAGE TEMPERATURES HAVE

DROPPED WELL BELOW FREEZING.

THIS ARCTIC FOX IS JUST THREE
MONTHS OLD.

LIFE IS ALL FUN AND GAMES NOW,
BUT SOON HE AND HIS SIBLINGS

WILL BE CAST OUT BY THEIR MOTHER
AND MUST SURVIVE THE WINTER

ALONE.

BUT WITH SNOW COVERING THE
GROUND, IT WILL BE A TOUGH TIME

TO LEARN HOW TO HUNT.

JUST A FEW DAYS LATER, AND HE'S
LEFT HIS FAMILY BEHIND.

FURRY SOLES PROTECT HIS FEET ON
SNOW AND ICE.

SHORT EARS AND A SHORT MUZZLE
REDUCE HIS SURFACE AREA,

MINIMIZING HEAT LOSS.

HIS THICK INSULATING FUR HAS
TURNED FROM AUTUMN'S TAWNY BROWN

TO A PERFECT WHITE.

THESE ARE ALL IMPORTANT
ADAPTATIONS TO LIFE IN THESE

BARREN WASTELANDS, BUT THEY'RE
USELESS UNLESS HE FINDS FOOD.

OLDER, MORE EXPERIENCED FOXES
KNOW HOW TO STASH RESOURCES FOR

TIMES SUCH AS THESE.

BUT SCAVENGING FROM OTHERS IS A
MEAGER EXISTENCE.

AND WHERE THERE'S CARRION,
THERE'S ALWAYS COMPETITION.

BY MIDWINTER, DEEP SNOW MAKES
FINDING FOOD NEARLY IMPOSSIBLE

FOR A YOUNG FOX.

BUT THIS IS WHERE ANOTHER OF HIS
SKILLS COMES INTO PLAY.

HE NOT ONLY HAS EXCELLENT SIGHT,
BUT PERFECTLY TUNED HEARING.

HIS EARS PICK UP THE FAINTEST
RUSTLE FROM BENEATH THE SNOW.

UNDERNEATH HIS FEET, ANOTHER
ANIMAL HAS TAKEN REFUGE FROM THE

COLD.

A DEER MOUSE HIDING UNDER THE
SNOW KEEPS IT SAFE FROM THE

WEATHER WHILE ALSO PROTECTING IT
FROM MOST PREDATORS.

IT WOULD MAKE A TASTY TREAT, BUT
IT'S NOT EASY TO CATCH SOMETHING

YOU CAN'T SEE.

WITH HIS PREY HIDING UNDER THREE
FEET OF SNOW, THIS ARCTIC FOX

WILL NEED BOTH SKILL AND LUCK.

HE LOOKS, LISTENS, THEN DIVES
RIGHT IN.

HE MUST JUDGE THE CORRECT
DISTANCE AND DEPTH OF SNOW.

MASTERING THIS ART WILL BE
CRUCIAL TO HIS SURVIVAL.

BUT IT TAKES PRACTICE.

WHILE AIRBORNE, HE ADJUSTS HIS
TRAJECTORY WITH A SLIGHT MOVE OF

THE TAIL, HELPING HIM MAKE...

...THE PERFECT LANDING.

MISSION ACCOMPLISHED.

THIS SKILL WILL SEE HIM THROUGH
THE WINTER AHEAD AND ENSURE HIS

SURVIVAL.

COMING UP, THESE HORSES ARE MORE
PREPARED THAN EVER TO TAKE ON

THE CHALLENGE OF A MONGOLIAN
WINTER.

BUT FIRST, WHAT IS THE LINK
BETWEEN THIS BIG CAT AND STAYING

WARM?

FIND OUT NEXT ON "EARTH
ODYSSEY".

.

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

DYLAN: POLAR BEARS LIVE IN SOME
OF THE COLDEST ENVIRONMENTS ON

EARTH, THRIVING ON ICEBOUND
ISLANDS AND FRIGID COASTLINES.

BUT WHILE MOST BEAR SPECIES ARE
FOUND IN THE WOODED PARTS OF THE

WORLD, THEY ENJOY COLD WEATHER
AS MUCH AS THEIR POLAR BEAR

BRETHREN.

IT MAY NOT BE THE NORTH POLE,
BUT MANY BEARS AND OTHER MAMMALS

LIKE THE ONE YOU'RE ABOUT TO
MEET MAKE THEIR HOMES IN THIS

SPECIAL TYPE OF FREEZING FOREST.

TAKE A LOOK.

A BIRCH FOREST.

IN THE DEPTHS OF EUROPE'S
WINTER, HOME TO A SOLITARY AND

SECRETIVE HUNTER,

THE EURASIAN LYNX.

FOR HALF THE YEAR, THESE ANCIENT
WOODLANDS ARE BLANKETED IN SNOW,

WHICH MAKES FINDING FOOD
INCREDIBLY CHALLENGING.

BUT THIS BIG CAT HAS SOME CLEVER
ADAPTATIONS TO SEE IT THROUGH.

A THICK FUR COAT OFFERS
PROTECTION AGAINST THE FREEZING

TEMPERATURES.

LONG LEGS WITH HUGE
SNOWSHOE-LIKE WEBBED PAWS HELP

HIM MOVE EFFORTLESSLY THROUGH
THE SNOW.

IN THE SUMMER, THIS ADEPT HUNTER
IS ABLE TO BRING DOWN PREY FOUR

TIMES ITS SIZE.

BUT IN WINTER, MANY LARGE PREY
SPECIES MIGRATE OUT OF THE

LYNX'S RANGE.

HE MUST EAT NEARLY FIVE POUNDS
OF MEAT A DAY.

HE CAN'T AFFORD TO BE PICKY, SO
HE'S LEARNED TO ADAPT HIS

HUNTING STYLE TO SUIT WHAT'S ON
OFFER IN THESE CHALLENGING

MONTHS.

EURASIAN LYNX HAVE VISION SO
SHARP, THEY CAN SPOT A SMALL

RODENT FROM 245 FEET AWAY.

BUT WITH VOLES TUNNELING FAR
BELOW THE THICK SNOW, THAT WON'T

HELP HIM NOW.

INSTEAD, HE MUST LISTEN.

BLACK TUFTS OF FUR ON HIS EARS
ENHANCE HIS HEARING...

[VOLE CHIPPING]

...PICKING UP EVEN THE FAINTEST
SOUND.

HE MUST TIME HIS AMBUSH
CAREFULLY.

ONE WRONG MOVE, AND HE'LL LOSE
HIS CHANCE.

AS HE GETS CLOSER, HE CAN
PINPOINT THE VOLE'S EXACT

LOCATION.

BUT THIS EXPERT PREDATOR KNOWS
NOT TO RUSH.

HE TAKES HIS TIME...

...UNTIL HE'S WITHIN STRIKING
DISTANCE.

IT MIGHT BE A SMALL MEAL, BUT IT
WILL KEEP HIM GOING.

FOR THE LYNX, LITTLE AND OFTEN
IS THE PERFECT WAY TO DINE.

COMING UP, THE HARSH MONGOLIAN
WINTERS ARE COMING IN HOT, BUT

THESE HORSES ARE READY FOR THE
CHALLENGE.

.

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

DYLAN: DESPITE THE CHALLENGES
THAT EXTREME WEATHER CAN BRING,

EVEN IN OUR PLANET'S MOST
INHOSPITABLE ENVIRONMENTS, SOME

ANIMALS FIND A WAY TO MAKE IT
THROUGH ALIVE.

WINTER ARRIVES EARLY ON THE
MONGOLIAN STEP, TURNING IT INTO

ONE OF THE MOST BITTER AND
HOSTILE PLACES ON EARTH.

BUT THERE'S ONE CREATURE HERE
WHO'S PREPARED FOR ITS

ONSLAUGHT, THE PRZEWALSKI'S
HORSE.

THESE ARE THE LAST WILD HORSES
ON EARTH.

THEY LIVE AT ALTITUDES UP TO
5,000 FEET, WHERE SUBZERO

TEMPERATURES AND STRONG WINDS
WOULD RESULT IN RAPID FROSTBITE

FOR ANY HUMAN.

FORTUNATELY, THEIR NEW WINTER
COATS HAVE ARRIVED JUST IN TIME,

ALONG WITH THICKER HAIR ON THEIR
MUZZLE AND NECK.

BUT THIS YEAR'S EARLY SNOWFALL
MEANS THE MOST NUTRITIOUS FOOD

IS NOW BURIED BENEATH TWO FEET
OF SNOW.

THIS TIGHT-KNIT FAMILY GROUP IS
MADE UP OF A STALLION, A FEW

MARES, AND THEIR YOUNG FOALS.

BUT WITH LITTLE MORE THAN
WITHERED GRASS TO SUSTAIN THEM,

THE HERD MUST TRAVEL UP TO 13
MILES A DAY TO FIND ENOUGH FOOD.

FOR SOME OF THEM, KEEPING UP
WITH THE JOURNEY IS TAKING ITS

TOLL.

BUT WHENEVER THEY STOP FOR A
REST, THEY GAIN COMPANY.

WITH THE GROUND BLANKETED BY
SNOW, MAGPIES WILL RELY ON THE

HORSES FOR FOOD.

THE MAGPIES EAT PARASITES TAKING
REFUGE DEEP IN THE WARMTH OF THE

HORSE'S COAT.

IN SUCH A BARREN LAND, THESE
TINY INSECTS ARE THE ONLY FOOD

FOR MILES.

THE MAGPIES HELP KEEP THE
HORSE'S SKIN CLEAN.

HOWEVER, CARRYING EXTRA CARGO
CAN BE JUST AS IRRITATING.

HAVING ALREADY GIVEN THE BIRDS A
FREE MEAL, PROVIDING A FREE RIDE

IS A STEP TOO FAR.

TO SURVIVE THE HARSH SEASON
AHEAD, THESE HORSES WILL NEED TO

FIND ENOUGH FOOD BENEATH THE
SNOW ALL WINTER LONG.

THANK YOU FOR JOINING US ON OUR
JOURNEY TO DISCOVER THE ANIMALS

WHO THRIVE IN THE FRIGID PARTS
OF OUR PLANET.

THEIR SURVIVAL IS A TESTAMENT TO
NATURE'S ABILITY TO ADAPT TO ANY

CIRCUMSTANCE, EVEN THE MOST
CHALLENGING.

WE HOPE TO SEE YOU NEXT TIME FOR
ANOTHER ADVENTURE ON "EARTH

ODYSSEY".
