SYMBOL, YOU KNOW YOU'RE

WATCHING TELEVISION THAT IS
EDUCATIONAL AND INFORMATIONAL.

THE MORE YOU KNOW ON NBC.

DYLAN: HI, EVERYONE, I'M DYLAN
DREYER, AND WE ARE ABOUT TO

EMBARK ON AN EPIC ADVENTURE HERE
ON "EARTH ODYSSEY".

TODAY, WE'RE ISLAND-HOPPING
ALONG THE CARIBBEAN TO SEE THE

WORLD'S RICHEST BIODIVERSITY UP
CLOSE.

UNDER THE COVER OF NIGHT, A
TROPICAL TURTLE HAS TRAVELED

THOUSANDS OF MILES FOR THE
PERFECT NESTING SPOT.

THIS CRAWLING CATERPILLAR IS
ABOUT TO BECOME A

MAGNIFICENT MONARCH.

LATER, WE'LL SEE THE FIRST STEPS
OF THESE MARINE MIGRATORS

HEADING FOR THE OPEN OCEAN.

BUT WE BEGIN OUR JOURNEY ON THE
ISLAND SHORES, WHERE BUILDING

THE PERFECT NEST IS A DAY AT THE
BEACH.

ALL OF THIS AND SO MUCH MORE ON
THIS EPISODE OF "EARTH ODYSSEY".

[MUSIC]

DYLAN: THE CARIBBEAN REGION
COVERS MORE THAN ONE MILLION

SQUARE MILES OF THE EARTH'S
SURFACE, BUT ONLY A TENTH OF

THAT IS LANDMASS.

WITH SUCH LIMITED LIVING SPACE,
IT SEEMS ALMOST IMPOSSIBLE TO

HAVE SO MANY DIVERSE AND
MAGNIFICENT SPECIES CALLING

THESE ISLANDS HOME, YET THAT
LACK OF LAND MEANS EACH ANIMAL

HAS TO GET CREATIVE WITH WHERE
THEY DECIDE TO LIVE.

A FEW STEPS AWAY FROM THE SHORE,
COLONIES OF LEAST TERNS MAKE

THEIR NESTS.

A SIMPLE DIP IN THE GROUND IS
ALL IT TAKES.

THERE'S NO ROOM IN THE CARIBBEAN
TO BE PICKY.

THE TERNS' ROMANTIC ETIQUETTE
DICTATES THAT A PRESENT IS AN

ESSENTIAL PART OF THE COURTSHIP.

WHAT COULD BE BETTER THAN A
FISH?

TERNS FORM THE IDEAL COUPLE.

BOTH PARENTS TAKE RESPONSIBILITY
FOR NESTING AND

RAISING THEIR YOUNG.

OUT OF THE THREE EGGS IN THIS
BROOD, ONLY TWO CHICKS WILL

REACH THE FLEDGLING AGE.

NESTING ON THE GROUND BRINGS
HAZARDS THAT THE TERNS WILL

CONFRONT AS A COUPLE.

THE COLONY IS AN EFFECTIVE MEANS
OF DEFENSE FOR THESE SEABIRDS,

BUT ANOTHER SPECIES THAT NESTS
ON THESE TROPICAL ISLANDS USES

QUITE A DIFFERENT TECHNIQUE.

IN NATURE, IT'S ADVISABLE TO BE
DISCREET, AND THE ANIMAL ON THE

SCREEN IS A MASTER OF THE ART OF
CAMOUFLAGE.

CAN YOU EVEN SEE IT?

TO EVADE ANY PREDATORY EYES, THE
ANTILLEAN NIGHTHAWK RELIES NOT

ONLY ON ITS PLUMAGE THAT MIMICS
THE LANDSCAPE, BUT ALSO ON ITS

REMARKABLE CAPACITY TO REMAIN
ABSOLUTELY STILL IN THE

FACE OF DANGER.

WHEN ON THE GROUND, IT IS VERY
HARD TO SPOT.

THIS FEMALE HAS BEEN SITTING ON
HER EGGS FOR 20 DAYS.

SUBJECTED TO THE CONSTANT SHIFTS
IN CLIMATE, SHE SITS ON HER EGGS

FOR 20 HOURS A DAY, REGARDLESS
OF THE TEMPERATURE ON THE GROUND

OR THE WEATHER CONDITION.

SHE PREFERS OPEN GROUND.

IT'S SAFER, AS IT ALLOWS HER A
360-DEGREE FIELD OF VISION.

WHEN IT COMES TO SIGHT, THE
NIGHTHAWK IS QUITE A PHENOMENON,

WITH EYES IN THE BACK OF ITS
HEAD.

THIS UNUSUAL BIRD SPENDS A LARGE
PART OF THE YEAR IN THE FORESTS

OF THE AMAZONIAN PLATEAU MORE
THAN 1,500 MILES SOUTH OF HERE.

IT HAS BEEN RETURNING HERE TO
BREED AT THE VERY SAME SPOT FOR

SEVERAL YEARS NOW.

OBVIOUSLY, THE FEMALE HAS NOT
MADE THE JOURNEY ALONE.

HER LIFETIME COMPANION JOINED
THE RIDE.

BUT DURING THE DAY, HE FREQUENTS
A DIFFERENT AREA.

COULD IT BE A PRECAUTION TO
DIVERT ATTENTION AWAY FROM HER?

POSSIBLY.

THE MALE HAS POSITIONED HIMSELF
ABOUT A HALF-MILE AWAY.

HE SPENDS HIS DAYS DOZING, BUT
NOT SLEEPING DEEPLY.

A CREATURE OF THE TWILIGHT AND
NIGHT, HE WAITS FOR THE SUN TO

SET BEFORE FLYING INTO ACTION.

THE MALE FINALLY TAKES FLIGHT.

ONCE AIRBORNE, THE NIGHTHAWK IS
QUITE ANOTHER BIRD, ITS DYNAMIC

DEMEANOR VERY DIFFERENT FROM HOW
IT IS ON THE GROUND.

STILL IN THE SAME PLACE, THE
FEMALE EMERGES FROM HER TORPOR

AND SEES HER PARTNER ARRIVING.

IT IS AT THIS POINT THAT THE
MALE ANNOUNCES HIS ARRIVAL WITH

A SERIES OF HEDGE-HOPPING DIVES.

THE SPEED OF ITS STOOP COMBINES
WITH THE ANGLE OF ITS WINGS TO

PRODUCE A CHARACTERISTIC HUMMING
SOUND.

[AIR WHOOSHING]

AT LAST, AFTER A DAY SPENT
SEPARATED AND ALONE, THE COUPLE

IS BACK TOGETHER AGAIN.

AS NIGHT FALLS, IT'S NEARLY TIME
FOR THEM TO TAKE A BREAK AND

THINK ABOUT FOOD.

A RARE AND FRAGILE SPECIES, THE
ANTILLEAN NIGHTHAWK DISAPPEARS

INTO THE NIGHT, TAKING A LITTLE
OF ITS MYSTERY WITH IT.

[BIRDS SCREECHING]

WHEN WE RETURN, ONE SPECIES'
EPIC JOURNEY TO LAY ITS EGGS HAS

BEEN UNDERWAY FOR MILLIONS OF
YEARS.

AND FOR THIS ICONIC INSECT,
BEAUTY TAKES MANY FORMS.

PLUS, THE REPTILIAN RACE IS ON
FOR THESE NEWBORNS CHARGING DOWN

THE BEACH.

ALL OF THIS COMING UP ON "EARTH
ODYSSEY".

.

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

DYLAN: UNDER COVER OF DARKNESS,
SEA TURTLES LAND UPON THE COAST.

THIS IS NO MISTAKE OR ERROR OF
JUDGMENT.

IT'S FOR A VITAL REASON.

AS ADULTS, THESE OCEANGOING
CREATURES RETURN TO THE SHORES

WHERE THEY WERE BORN EVERY TWO
YEARS OR SO TO BREED.

THIS GREEN SEA TURTLE HAS JUST
FINISHED DIGGING ITS NEST.

SHE USES IT TO LAY AROUND A
HUNDRED EGGS THAT LOOK LIKE

GLOSSY GOLF BALLS.

THEIR SOFT SHELLS CAN EASILY
ABSORB ANY IMPACT AT THE BOTTOM

OF THE NEST.

ONCE HER EGGS ARE LAID, SHE
SEALS THE NEST.

THE SAND HAS A VITAL ROLE TO
PLAY.

ITS TEMPERATURE OVER THE NEXT
EIGHT WEEKS WILL NOT ONLY HAVE

AN INFLUENCE ON THE INCUBATION
PERIOD, BUT WILL ALSO BE A

DETERMINING FACTOR IN THE GENDER
OF THE HATCHLINGS.

UP TO 80 DEGREES FAHRENHEIT,
THEY WILL BE MALE.

ANY WARMER THAN THAT, AND THE
YOUNG WILL BE MOSTLY FEMALE.

AFTER SPENDING 40 MINUTES
SWEEPING THE SAND TO HIDE ANY

TRACE OF HER NEST, THE FEMALE
LEAVES HER EGGS TO THEIR FATE

AND RETURNS TO THE OCEAN.

WHILE THIS MIGHT SEEM LIKE A
HIGH-RISK STRATEGY, EVIDENCE IS

THAT IT WORKS.

MARINE TURTLES COME FROM A LONG
LINEAGE WHICH GOES BACK 200

MILLION YEARS.

NOW, THAT'S SOME IMPRESSIVE
FAMILY HISTORY.

UNDER THESE TROPICAL SKIES,
THERE'S A NATURAL ENVIRONMENT

WHICH IS NEITHER FULLY LAND NOR
SEA.

IT'S A VAST AREA OF FOREST
GROWING OUT OF THE WATER ITSELF.

THESE ARE CALLED MANGROVE
FORESTS, AND THEY PLAY A

PRIMORDIAL ROLE HERE IN THIS
CARIBBEAN ENVIRONMENT.

THEY'RE SPAWNING AREAS FOR
MARINE SPECIES AND ACT AS WATER

FILTERS, FORMING BUFFER ZONES
WHICH PROTECT THE

SHORES FROM HURRICANES.

AT LOW TIDE, THE MUDDY GROUND
BELONGS TO THE CRABS...

...ESPECIALLY FIDDLER CRABS,
WHOSE MALES ARE RECOGNIZABLE BY

THEIR SINGLE OVERSIZED,
HYPERDEVELOPED CLAW.

THE SMALL PINCER IS USEFUL FOR
RUMMAGING IN THE SILT.

ITS SIZE IS ADAPTED TO ITS SMALL
MOUTHPARTS.

BUT WHAT IS THE BIGGER ONE FOR?

EACH MALE IS LORD OF ITS OWN
TERRITORY, A BURROW THAT HE

BUILDS, MAINTAINS, AND DEFENDS
FIERCELY.

THE LARGE CLAW IS IN FACT A
WEAPON, BUT IT IS MAINLY A

DETERRENT, AS VIOLENT
CONFRONTATION IS RARE.

BUT ITS MAIN ROLE IS AS PART OF
ITS DISPLAY, A SHOW DURING WHICH

EACH MALE PERFORMS A SERIES OF
MOVEMENTS USING THIS

REMARKABLE APPENDAGE.

THE AIM IS TO ATTRACT THE
SMALL-PINCERED FEMALES TO LAY

THEIR EGGS IN HIS NEST.

AND WHO COULD RESIST SUCH
GRACEFUL CHOREOGRAPHY?

IN THIS NEW WORLD CRUSTACEAN
ORCHESTRA, EACH SPECIES OF

FIDDLER HAS ITS OWN RHYTHM,
FREQUENCY,

AND SEQUENCE OF MOVES.

IN THE HEART OF THE MANGROVE
FOREST, THESE LITTLE CRABS HAVE

DEVELOPED A SIMPLE, YET
EFFECTIVE METHOD OF

COMMUNICATION BY WAY OF BODY
LANGUAGE.

IT MAKES EACH OF THEM FLUENT IN
THE LANGUAGE OF LOVE.

COMING UP, WE SEE THE EVOLUTION
OF ONE OF NATURE'S

MOST REVERED ROYALS.

AND WE GET A RARE GLIMPSE AT
SOME ISLAND INFANTS READY FOR

LIFE AT SEA WHEN "EARTH ODYSSEY"
RETURNS.

.

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

DYLAN: THE CARIBBEAN MAY BE
BEST KNOWN FOR ITS MAGNIFICENT

MENAGERIE OF MAMMALS, REPTILES,
AND BIRDS, BUT IT ALSO HAS AN

IMPRESSIVE INSECT POPULATION
WITH HUNDREDS OF DIFFERENT

SPECIES THRIVING ACROSS EACH OF
THESE TROPICAL ISLANDS.

SOME ARE A CLASSIC NUISANCE,
LIKE THE COMMON MOSQUITO, WHILE

OTHERS ARE A RARE FIND, LIKE THE
BIZARRE HARLEQUIN BEETLE.

BUT NONE ARE AS FAMOUS OR AS
MAJESTIC AS THE

CARIBBEAN'S MOST REGAL
BUTTERFLY.

BEHIND THE CARIBBEAN'S MANGROVES
AND MARSHY FORESTS, THERE ARE

WATER MEADOWS.

THE FOREST CLEARINGS HAVE BECOME
MORE AND MORE POPULATED BY

FLOWERING PLANTS.

ONE OF THESE, THE TROPICAL
MILKWEED, PLAYS A MAJOR ROLE IN

THE LIFE OF A MONARCH BUTTERFLY.

MONARCHS ARE NORMALLY NOMADIC,
BUT THEY HAVE DECIDED TO SETTLE

DOWN PERMANENTLY HERE IN THE
CARIBBEAN.

FOR MONARCH BUTTERFLIES, THIS IS
MATING SEASON.

ONCE FERTILIZED, THE FEMALES ARE
READY TO PRODUCE

A NEW GENERATION.

TROPICAL MILKWEED IS THE PERFECT
PLACE FOR A MONARCH

TO LAY ITS EGGS.

AFTER JUST A FEW DAYS, TINY
CATERPILLARS APPEAR.

THEY WILL GROW VERY QUICKLY.

AFTER TWO WEEKS AND A FEW
MOLTING MUTATIONS, THEIR SIZE

WILL INCREASE BY 200 TIMES.

THE MILKWEED THAT THEY FEED ON
CONTAINS TOXIC COMPOUNDS TO

WHICH THE CATERPILLARS ARE
IMMUNE.

BY CONCENTRATING THE TOXINS
WITHIN THEIR BODIES, THE LARVAE

ARE WELL-ARMORED AGAINST ANY
PREDATOR.

THE CATERPILLARS HAVE FINISHED
GROWING.

THEIR NEXT MOLT WILL BE THEIR
LAST.

AROUND TEN DAYS LATER, A
BRAND-NEW CREATURE IS

READY TO EMERGE.

THIS CHRYSALIS, THE FRAGILE
ENVELOPE WITHIN WHICH THE

CATERPILLAR'S SLOW METAMORPHOSIS
HAS TAKEN PLACE, NOW OPENS TO

REVEAL THE NEW CREATURE.

THE YOUNG BUTTERFLY SPREADS ITS
WINGS AND PUMPS HEMOLYMPH, OR

BLOOD, THROUGH ITS BODY.

THIS LIQUID WILL IRRIGATE AND
STRENGTHEN EACH OF ITS LIMBS.

THEN COMES THE ULTIMATE
CHALLENGE, THAT OF WARMING ITS

MOTOR MUSCLES ENOUGH TO ENABLE
IT TO FLY.

JUST LIKE ITS PREDECESSORS, THE
MONARCH WILL CRISSCROSS THE

CARIBBEAN SHORES IN SEARCH OF
ITS OWN HOME IN THE WILD.

THESE SMALL MANGROVE ISLANDS
SERVE AS RESTING PLACES FOR

BIRDS COMING IN FROM THE OPEN
SEA.

ONE OF THEM LEADS QUITE AN
UNBELIEVABLE LIFE...

...A BIRD WHOSE LIFE IS
INEXTRICABLY LINKED TO THE

OCEAN, THAT HUNTS AND EATS ONLY
MARINE PREY.

IT SPENDS ITS LIFE GLIDING ABOVE
THE SEA DAY AND NIGHT.

IT SLEEPS WHILE IN THE AIR,
CARRIED BY POWERFUL TROPICAL

UPWARD CURRENTS WHICH CAN LIFT
IT TO AN ALTITUDE OF ALMOST

10,000 FEET.

ITS FIVE-FOOT WINGSPAN, NARROW
WINGS, AND LIGHT BODY ALLOW IT

TO GLIDE WITHOUT EFFORT.

IRONICALLY, ITS PLUMAGE IS NOT
WATERPROOF, AND ITS FEATHERS

MUST HAVE NO CONTACT WITH WATER,
OR ELSE IT WILL DROWN.

BUT THEY HAVE ADAPTED, ABLE TO
LIVE ON THE EDGE OF LIFE AND

DEATH WITH PRACTICED EASE.

THE MAGNIFICENT FRIGATE BIRD IS
A LIVING PARADOX AND PROOF THAT

MOTHER NATURE IS ALWAYS
UNEXPECTED.

AFTER A LONG WAIT, THESE
HARD-SHELL HATCHLINGS ARE READY

TO SHIP OUT TO SEA.

THIS AND MORE WHEN "EARTH
ODYSSEY" RETURNS.

.

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

DYLAN: ON THE LOWER COASTS OF
THESE CARIBBEAN ISLANDS, THE

SALT MARSHES OFFER SANCTUARY TO
MANY SPECIES OF SHOREBIRD.

PERFECTLY SITUATED BETWEEN THE
TWO AMERICAS, THE WEST INDIES

ARE A STAGING POST FOR MIGRATORY
BIRDS.

SOME STOP HERE TWICE A YEAR ON
THEIR WAY TO THEIR BREEDING

GROUNDS IN THE CANADIAN ARCTIC
AND ON THEIR WAY BACK TO THEIR

SOUTH AMERICAN WINTER HOMES.

OTHERS HAVE CHOSEN THIS PLACE TO
SETTLE AND ENSURE THE ARRIVAL OF

THE NEXT GENERATION, LIKE THIS
SNOWY PLOVER GETTING COMFORTABLE

ON THE WATER'S EDGE.

MEANWHILE, AFTER A TWO-MONTH
INCUBATION PERIOD, THE YOUNG SEA

TURTLES ARE GETTING READY TO
EMERGE FROM THE SAND TO HEAD TO

THE OCEAN.

IT TAKES TRUE PERSEVERANCE FOR
THESE TURTLES TO REACH ADULTHOOD

AND BE ABLE TO COME AND LAY
THEIR OWN EGGS ON THESE SHORES.

THE ISLANDS OF THE CARIBBEAN ARE
ONE OF THE 35 HOTSPOTS OF

GLOBAL BIODIVERSITY.

THEY ARE THE RICHEST, THE MOST
FRAGILE, AND THE MOST VULNERABLE

ECOSYSTEMS ON THE PLANET.

THESE TREASURES ARE UNLIKE ANY
OTHER AND OFFER US A GLIMPSE

INTO THE INCREDIBLE BEAUTY OF
THE WILD.

THE CARIBBEAN IS A WEALTH OF
BIODIVERSITY WITH CREATURES AS

UNIQUE AND BEAUTIFUL AS THE
LANDSCAPE THEY CALL HOME.

THROUGH THE GENERATIONS, THESE
ANIMALS HAVE ADAPTED TO BECOME

CARIBBEAN SPECIALISTS, ABLE TO
NAVIGATE THE LIMITED RESOURCES

AND BOUTS OF EXTREME WEATHER
WITH EXPERT PRECISION, DOING

EVERYTHING IT TAKES TO THRIVE IN
THE WILD.

THANK YOU FOR JOINING US TODAY
ON OUR TROPICAL EXCURSION.

I HOPE TO SEE YOU FOR OUR NEXT
ADVENTURE ON

"EARTH ODYSSEY".
