ANNOUNCER: WHEN YOU SEE THIS
SYMBOL YOU KNOW YOU'RE

WATCHING TELEVISION THAT'S
EDUCATIONAL AND INFORMATIONAL

THE MORE YOU KNOW ON NBC.

DYLAN: HEY THERE,
I'M DYLAN DREYER,

AND THIS IS “EARTH ODYSSEY.”

ON TODAY'S SHOW, WE
HEAD TO THE HEBRIDES,

AN ISLAND CHAIN OFF THE
COAST OF SCOTLAND.

HERE, SEA MAMMALS LIKE
THE GREY SEAL TAKE UP

RESIDENCE ON THE
DESERTED BEACHES,

WHERE THEY MUST FIGHT
FOR THEIR VERY EXISTENCE.

PLUS, WE'LL WITNESS A
SHOWDOWN BETWEEN TWO RED

DEER.

FIND OUT WHO WILL BE THE
VICTOR AND WHO WILL RUN

FOR THE HILLS, AND
LATER, WE'LL UNCOVER THE

MYSTERIES OF AN ANCIENT
CIVILIZATION WHO ROAMED

THESE ISLANDS
THOUSANDS OF YEARS AGO.

[MUSIC]

DYLAN: HERE AT RIPLEY'S
AQUARIUM OF MYRTLE BEACH,

YOU'LL FIND MANY CREATURES
WHO RELY ON OTHER SPECIES

TO SURVIVE AND FLOURISH.

THAT SYMBIOTIC
RELATIONSHIP IS ALSO

PRESENT BETWEEN ANIMALS
WHO LIVE IN THE SEA AND

THOSE WHO LIVE IN THE
SKY, AND NOWHERE IS THIS

COEXISTENCE MORE APPARENT
THAN ON A MYSTERIOUS CHAIN

OF ISLANDS IN GREAT
BRITAIN CALLED THE

HEBRIDES.

LYING JUST OFF THE
WEST COAST OF SCOTLAND,

THE HEBRIDES ARCHIPELAGO
IS MADE UP OF MORE THAN

FIVE HUNDRED
ISLANDS AND ISLETS.

ISOLATION FROM THE
MAINLAND HAS MADE THE

HEBRIDES THE PERFECT
BREEDING GROUND FOR

MILLIONS OF CREATURES,
EARNING IT THE NAME

EUROPE'S LAST WILDERNESS.

EVER SINCE THEY WERE
EXPOSED AT THE END OF THE

ICE AGE, THE HEBRIDES
ISLANDS HAVE BEEN A LAND

OF MYSTERY.

EARLY SAILORS RECOUNTED
TALES OF MERMAIDS WHO

WOULD CALL OUT
FROM COASTAL CAVES...

...LURING SAILORS INTO THE
ROCKS AND INTO A WATERY

GRAVE.

ALTHOUGH MERMAIDS ARE
THE STUFF OF LEGENDS,

THESE EERIE CALLS CAN
STILL BE HEARD TODAY.

[GREY SEAL WHIMPERING]

GREY SEALS TAKE
REFUGE IN THESE CAVERNS.

[WHIMPERING CONTINUES]

AND THEY ARE THE MOST
VOCAL OF ALL SEAL SPECIES.

HALF OF THE WORLD'S
POPULATION OF GREY SEALS

LIVES ALONG THE
BRITISH COAST.

THE MONACH ISLES ON THE
OUTER HEBRIDES CHAIN HOSTS

ONE OF THE LARGEST
GATHERINGS OF GREY SEALS

ON THE PLANET.

EACH WINTER, MORE THAN 35,000

OF THESE SEA MAMMALS
ARRIVE ON THE ISLAND'S

ISOLATED SHORES.

ALTHOUGH MOTHERS GIVE
BIRTH TO JUST ONE PUP AT A

TIME, AROUND NINE THOUSAND
ARE BORN HERE EVERY YEAR.

PUPS NURSE FOR
JUST 18 DAYS.

THE MOTHER'S
MILK IS SO RICH,

IT CONTAINS
AROUND 60 PERCENT FAT.

THIS NUTRIENT-RICH MILK
IS ESSENTIAL SINCE THESE

YOUNGSTERS NEED TO PACK ON
ABOUT FIVE POUNDS A DAY.

IN AROUND
THREE WEEKS' TIME,

THEIR WEIGHT
MORE THAN TRIPLES.

ONCE THE PUPS ARE WEANED,
THEY'RE ABANDONED BY THEIR

MOTHERS AND LEFT TO
FEND FOR THEMSELVES.

WITHOUT THE BURDEN
OF A NURSING CHILD,

THE MOTHER IS
FREE TO MATE AGAIN.

IN ABOUT TWO WEEKS' TIME,
HUNGER WILL DRIVE THESE

ORPHANED PUPS INTO THE
OCEAN IN SEARCH OF FOOD.

[SEAL GROWLS]

BULL SEALS PLAY NO PART IN
THE RAISING OF THE YOUNG.

THEY HAVE A MORE
IMPORTANT MISSION.

THE OLDER MALES MUST
BATTLE OVER TERRITORIAL

RIGHTS AND ACCESS
TO THE FEMALE SEALS.

IT TAKES ABOUT TEN YEARS
FOR THE OLDER MALES TO

BECOME LARGE AND STRONG
ENOUGH TO STAKE THEIR

CLAIM.

SOMETIMES AN INTIMIDATING
SNARL CAN WARD OFF A

POTENTIAL RIVAL.

[SEAL GROWLS]

BUT THESE TWO WARRIORS
APPEAR TO HAVE MET THEIR

MATCH.

FIGHTS BETWEEN BULL SEALS
CAN GET DOWN AND DIRTY,

OFTEN LEADING TO A
SITUATION WHERE ONLY ONE

WALKS, OR SCOOTS, AWAY.

THIS MALE REALIZES HE'S NO
MATCH AND EVENTUALLY BACKS

DOWN.

THE WATERS OFF THE
HEBRIDES ARE TEEMING WITH

COUNTLESS VARIETIES OF FISH.

SO, IT'S NO SURPRISE THAT
GREY SEALS HAVE TO SHARE

THIS FOOD SOURCE WITH
SOME OF THE LARGEST SEA

CREATURES ON THE PLANET.

MINKE WHALES WEIGH UP TO
15 TONS AND CAN MEASURE UP

TO 30 FEET IN LENGTH.

THESE MAMMOTH ANIMALS
LUNGE AT THEIR PREY FROM

BENEATH THE SURFACE,
SWALLOWING LARGE VOLUMES

OF FISH IN A SINGLE GULP.

THE WHALES GENERALLY
LIVE SOLITARY LIVES,

BUT THEY SOMETIMES GATHER
IN GROUPS OF TEN OR MORE

WHEN FEEDING.

BUT MINKE WHALES AREN'T
THE ONLY ONES LINING UP

FOR THIS BUFFET.

24 SPECIES OF
WHALES, DOLPHINS,

AND PORPOISES
PATROL THESE WATERS,

INCLUDING
BRITAIN'S LARGEST FISH.

MEET THE BASKING SHARK.

THIS SLACK-JAWED CREATURE
CAN REACH UP TO 22 FEET IN

LENGTH AND HAS A DORSAL
FIN UP TO FOUR-AND-A-HALF

FEET HIGH.

THEY'RE DRAWN TO THE
HEBRIDES PLANKTON-RICH

WATERS, WHERE THEY REMAIN
CLOSE TO THE SURFACE TO

FEED.

THESE MASSIVE
SHARKS FILTER AROUND A

MILLION-AND-A-HALF LITERS
OF WATER EVERY HOUR,

TRAPPING THE TINY PLANKTON
IN THEIR ODD-LOOKING

GILLS.

ANOTHER MIGHTY BEAST IS
ALSO FIGHTING FOR FOOD AND

SURVIVAL.

COMING UP, JOIN US AS WE
WITNESS AN EPIC SHOWDOWN

BETWEEN TWO
RED DEER STAGS.

WHO WILL CLAIM VICTORY,
AND WHO WILL BACK DOWN?

ALL THIS AND MORE OF
THE WILD HEBRIDES WHEN WE

RETURN.

.

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

ANNOUNCER: THIS EPISODE
OF “EARTH ODYSSEY WITH DYLAN

DREYER” IS BROUGHT TO
YOU BY RIPLEY'S AQUARIUMS.

DYLAN: THE HEBRIDES
ISLANDS IS HOST TO

CREATURES BOTH
GREAT AND SMALL.

IT'S A PLACE WHERE
BIRDS, SEA LIFE,

AND LAND
ANIMALS ALL COEXIST.

THE ISLAND OF RUM IS
IN THE HEART OF INNER

HEBRIDES.

THOUGH IT'S MADE UP OF
TALL PEAKS AND ROLLING

HILLS, IT WAS ONCE A
PREHISTORIC VOLCANO ACTIVE

AROUND 25
MILLION YEARS AGO.

TODAY, IT'S HOME
TO THE RED DEER,

THE THIRD LARGEST
DEER IN THE WORLD.

AROUND NINE HUNDRED OF
THEM ROAM THIS REMOTE

ISLAND.

[DEER GROANING]

THE POPULATION HAS
REMAINED RELATIVELY STABLE

DUE TO BEING ISOLATED
FROM MAINLAND PREDATORS.

WHILE THE RED DEER DON'T
NEED TO WORRY ABOUT BEING

BOTHERED BY OUTSIDE FOES,
THERE'S PLENTY OF CONFLICT

WITHIN THE
HERDS THEMSELVES.

MATURE MALES WEIGH AROUND
450 POUNDS AND STAND

ALMOST FIVE FEET
TALL AT THE SHOULDERS,

AND COMPETITION FOR
FEMALES MEANS ONLY THE

STRONGEST WILL
WIN THE PRIZE.

THIS STAG HAS SEPARATED
FROM THE REST OF THE MALES

AND IS LOOKING FOR SOME
FEMALE COMPANIONSHIP.

HE'S MANAGED TO ATTRACT
THE ATTENTION OF A SMALL

GROUP OF DOES.

[DEER GROANING]

BUT HE'S NOT THE ONLY
ONE UNDER CONSIDERATION.

[DEER GROANING]

RIVAL BUCKS CHALLENGE
THEIR OPPONENT BY WALKING

PARALLEL TO HIM
AND LETTING OUT AN

INTIMIDATING ROAR.

[DEER GROANING]

ONCE THE TWO HAVE
SIZED EACH OTHER UP,

THE BATTLE BEGINS.

THESE INTENSE BOUTS OF
SPARRING ARE VIOLENT,

BUT WITH BREEDING
RIGHTS AT STAKE,

THESE MALES ARE
WILLING TO TAKE THE RISK.

THE INDIVIDUAL CLASHES ARE
USUALLY OVER IN A MATTER

OF MINUTES, BUT WILL
CONTINUE ON THROUGHOUT THE

FOUR-WEEK MATING SEASON.

THE WEAKER BUCK MAKES THE
SMART DECISION TO RETREAT

AND FIGHT ANOTHER DAY,

BUT DEER AREN'T THE ONLY

HOOVED ANIMALS ROAMING
THE ISLAND GRASSLANDS.

TO THE FAR WEST OF THE
OUTER HEBRIDES SITS ONE OF

THE MOST HOSTILE AND
ISOLATED ISLANDS IN THIS

ARCHIPELAGO, ST. KILDA.

HERE YOU WILL FIND ONE OF
THE MOST PRIMITIVE HERDS

OF ANIMALS,
THE SOAY SHEEP.

THESE GRAZING MAMMALS HAVE
CALLED THESE ISLANDS HOME

FOR MORE THAN
FOUR THOUSAND YEARS.

WHILE THEY'RE SMALLER
THAN DOMESTIC SHEEP,

THEY'RE ALSO
HEARTIER AND MORE AGILE,

AND UNLIKE THEIR
LIGHT-COLORED RELATIVES,

SOAY SHEEP SHED
THEIR COATS NATURALLY,

SO THEY DON'T
REQUIRE SHEARING.

THEIR EXTRAORDINARILY LONG
REIGN ON THE ISLANDS IS

DUE IN PART TO THE
FACT THAT THEY DON'T HERD

TOGETHER LIKE
ORDINARY SHEEP.

WHENEVER A THREAT APPEARS,
MEMBERS OF THE GROUP

SCATTER IN ALL DIRECTIONS,
MAKING THEIR CAPTURE

DIFFICULT FOR PREDATORS.

AROUND TWO THOUSAND
SOAY SHEEP ROAM ST. KILDA

TODAY, BUT HOW DID THESE
ANIMALS END UP ON THESE

ISLANDS?

IT TURNS OUT THEY WERE
BROUGHT HERE THOUSANDS OF

YEARS AGO DURING THE
BRONZE AGE BY MAN HIMSELF.

UP NEXT, FIND OUT WHY FISH
ARE NO MATCH FOR THESE

AVIAN HUNTERS WHO CAN TURN
THEMSELVES INTO PRECISION

TORPEDOES WHEN
“EARTH ODYSSEY” RETURNS.

.

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

DYLAN: ON EVERY
“EARTH ODYSSEY,

WE FIND A DIVERSE
GROUP OF WILDLIFE ALL WITH

UNIQUE TRAITS THAT
SERVE THEM IN THE WILD.

WELL, YOU'RE ABOUT TO
MEET ANOTHER ANIMAL WITH A

SPECIAL TALENT FOR
SURVIVING AND THRIVING.

TAKE A LOOK.

THE VAST SEA LIFE IN
THE OCEAN SURROUNDING THE

HEBRIDES PROVIDES A BOUNTY
OF FOOD FOR THE AQUATIC

BIRDS WHO SOAR IN THE
SKIES ABOVE THE CRASHING

WAVES.

BUT FEW CAN COMPETE WITH THE
MASTER DIVER OF THEM ALL.

NORTHERN GANNETS HAVE A
WINGSPAN OF AROUND SIX

FEET ACROSS, MAKING
THEM GRACEFUL FLYERS AND

SKILLFUL HUNTERS.

UNLIKE MOST BIRDS, THEY
HAVE FORWARD-FACING EYES,

GIVING THEM RAZOR
SHARP DEPTH PERCEPTION.

THIS ALLOWS THEM TO
ACCURATELY ESTIMATE HOW

CLOSE THE FISH ARE TO
THE SURFACE OF THE WATER.

ONCE LOCKED IN
ON THEIR TARGET,

THEY FOLD BACK THEIR WINGS
AND MAKE THEIR PLUMMETING

DIVE.

GANNETS HIT THE WATER AT
MORE THAN 60 MILES AN HOUR

TO CAPTURE THEIR PREY.

AT THE MOMENT OF IMPACT,
THEY STRETCH THEIR BODIES

INTO A STREAMLINED
TORPEDO-LIKE SHAPE.

POCKETS OF AIR CELLS
BETWEEN THEIR SKIN AND

MUSCLES HELP
CUSHION THE BLOW.

WITH THIS KIND OF
PREDATORY FINESSE,

IT'S NO WONDER WHY THESE
BIRDS HAVE SURVIVED HERE

FOR TENS OF
THOUSANDS OF YEARS.

COMING UP, WE'LL UNCOVER
HOW ISLAND SEABIRDS LED TO

THE FORMATION OF
AN ANCIENT IRON AGE

CIVILIZATION.

.

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

DYLAN: IT IS BELIEVED THAT
HUMAN KIND FIRST ARRIVED

ON ST. KILDA SOMETIME
DURING THE BRONZE AGE MORE

THAN FIVE
THOUSAND YEARS AGO.

ANCIENT HERDERS MIGRATED
HERE WITH THE PRIMITIVE

RELATIVES OF
MODERN-DAY SHEEP,

BUT EARLY HUMANS ALSO
RELIED ON ANOTHER ANIMAL

FOR THEIR SURVIVAL.

THE CLIFFS OF ST. KILDA
ARE HOME TO SOME OF THE

LARGEST POPULATION OF
SEABIRDS IN THE WORLD,

INCLUDING
PUFFINS, FULMARS,

AND GANNETS.

THIS VAST SUPPLY OF
SEABIRDS BECAME A MAIN

STAPLE FOR THESE
ANCIENT PEOPLE.

RESIDENTS ATE AN AVERAGE
OF 115 PUFFINS A YEAR.

WHILE THE FOOD SOURCE
WAS PLENTIFUL DURING THE

WARMER MONTHS OF THE YEAR,
IT WAS ALSO SEASONAL.

AT THE END OF THE SUMMER,
THE ISLAND CLIFFS BECAME

BARE AS BIRDS MIGRATED
TOWARD TEMPERATE CLIMATES.

THIS MILLENNIUM'S OLD
CIVILIZATION CAME TO AN

ABRUPT END IN 1930.

FOLLOWING FOOD
SHORTAGE AND DISEASE,

THE LAST 36 RESIDENTS WERE
EVACUATED TO THE MAINLAND.

BUT THESE
TWO-THOUSAND-YEAR-OLD IRON

AGE DWELLINGS STILL STAND
AS A TESTAMENT TO MAN'S

PREHISTORIC
PRESENCE ON THE ISLAND.

THE ISLANDS OF LEWIS
AND HARRIS ON THE OUTER

HEBRIDES PROVIDES EVEN
MORE EVIDENCE OF EARLY MAN

INHABITING THE REGION.

THESE
SIX-THOUSAND-YEAR-OLD PEAT

BOGS USED TO BE WOODLAND
AREAS UNTIL NEOLITHIC

HERDERS LEVELED THEM TO
ALLOW THEIR DEER TO GRAZE.

TODAY, THE ISLAND REMAINS
VIRTUALLY TREELESS.

AND THE STANDING STONES
OF CALLANISH GIVE US EVEN

MORE CLUES TO
THIS ANCIENT WORLD.

THESE TOWERING MONUMENTS
WERE ERECTED AROUND FOUR

THOUSAND YEARS AGO, LONG BEFORE
ROME WAS EVEN HEARD OF.

13 STONES AVERAGING ABOUT
13 FEET TALL FORM A CIRCLE

ABOUT 42 FEET ACROSS.

A NUMBER OF MYTHS SURROUND
THE ORIGINS OF THIS

MONUMENT.

SOME LEGENDS SAY THAT
GIANTS WHO ONCE LIVED HERE

WERE TURNED INTO STONE AS
PUNISHMENT FOR REFUSING TO

CONVERT TO CHRISTIANITY.

OTHERS TELL OF A GHOSTLY
FIGURE WHO IS SAID TO WALK

THROUGH THE CIRCLE AT
THE START OF THE MIDSUMMER

SOLSTICE.

ANOTHER THEORY POINTS TO
CALLANISH BEING AN ANCIENT

BURIAL SITE, BUT THE TRUE
PURPOSE OF THE STRUCTURE

REMAINS A MYSTERY
TO THIS VERY DAY.

HEY, THANKS FOR JOINING
ME ON THIS SPECTACULAR

JOURNEY THROUGH THE
GREATEST PLACES ON EARTH.

WE'LL SEE YOU NEXT TIME FOR
ANOTHER “EARTH ODYSSEY.”
