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 EVERYONE, I'M DYLAN
DREYER.

GET READY FOR AN INCREDIBLE
ADVENTURE ON "EARTH ODYSSEY."

TODAY, WE'RE TAKING OFF TO SEE
SOME FANCY AND FASCINATING

FEATHERED CREATURES FROM ACROSS
THE WORLD.

WE'LL MEET AFRICA'S AVIAN
SINGING SENSATIONS.

AND CATCH UP WITH A COLORFUL
CHARACTER FROM ANCIENT FOLKLORE.

LATER, WE'LL SEE WHY THIS STORK
IS READY TO GET BACK IN THE

SADDLE.

BUT OUR JOURNEY BEGINS IN A
TROPICAL FOREST WHERE ONE BIRD

HAS TAKEN CLIMBING TO NEW
HEIGHTS.

GET READY FOR SOME HIGH-FLYING
ACTION RIGHT HERE ON "EARTH

ODYSSEY."

[MUSIC]

DYLAN: IN GENERAL, FOR US, BIRDS
EQUAL FLYING.

WINGED, GRACEFUL CREATURES
SOARING THROUGH THE SKY.

HOWEVER, THERE IS A WHOLE GROUP
OF BIRDS DEFINED BY THEIR

INABILITY TO TAKE OFF AND PREFER
A LIFE MORE GROUNDED.

LIKE GALLIFORMES, AN ORDER OF
HEAVY-BODIED GROUND-FEEDING

SPECIES THAT INCLUDE TURKEYS AND
QUAIL.

HOWEVER, THERE ARE A FEW MORE
EXOTIC EXAMPLES OF THESE

FLIGHTLESS FANCIES HIDDEN AMONG
THE TREES IN CENTRAL AMERICA.

TAKE A LOOK.

IT'S WILD AVOCADO SEASON IN THIS
LUSH CORNER OF COSTA RICA.

AND THAT MEANS A FEW AVIAN
APPETITES ARE AT THEIR PEAK.

[MUSIC]

DYLAN: A GOOD REASON TO INCITE A
LITTLE ENVY.

A TREE-DWELLING SPECIES OF THE
GALLIFORMES, OR BIGGER-BODIES,

MOSTLY FLIGHTLESS BIRDS, HAS
LOCATED THIS NOURISHING MANOR.

IT'S A BLACK GUAN, ENDEMIC TO
COSTA RICA AND PANAMA.

THIS CLIMBING BIRD IS VERY MUCH
AT HOME IN THE AGUACATILLOS

TREES.

ITS FEEDING HABITS ARE VERY
DIFFERENT.

IT ASKS NO QUESTIONS, IT JUST
CONSUMES.

ITS LARGE SIZE ALLOWS IT TO
SWALLOW THE FRUIT WHOLE AND ITS

ANATOMY ALLOWS THE PITS TO BE
EVACUATED BY A NATURAL MEANS.

ANOTHER RESIDENT OF THE CLOUD
FOREST IS THE EMERALD TOUCANET.

AS AN OMNIVORE, THESE BIRDS FEED
ON VEGETATION, FRUITS AND EVEN

SMALL ANIMALS LIKE INSECTS.

BUT THEY'LL OCCASIONALLY HUNT
FOR OTHER BIRDS' CHICKS AND

EGGS.

THAT MAKES THEM A TROUBLESOME
TROPICAL NEIGHBOR FOR OTHER

LOCAL AVIANS.

HOWEVER, TODAY, A MENU FAVORITE
FOR THE EMERALD TOUCANET ARE

THESE PERFECTLY-RIPE AVOCADOS.

THEY HAVE THEIR OWN SPECIAL
FEEDING METHOD.

FIRST, THEY USE THEIR BEAKS TO
PIT THE AVOCADO.

WHOOPS, DROPPED IT.

LUCKILY, THERE'S PLENTY MORE
WHERE THAT CAME FROM.

AND THIS TIME, THERE'S NO
PROBLEM FINISHING ITS SNACK.

ANOTHER IMPRESSIVE AVIAN
APPETITE IS THAT OF THE QUETZAL.

THIS ONE SWALLOWED A MASSIVE
AVOCADO 20 MINUTES AGO.

THE QUETZAL CERTAINLY TAKES ITS
TIME TO DIGEST.

FIRST, THE FRUIT PASSES THROUGH
THE PROVENTRICULUS, AN ORGAN

THAT PRE-DIGESTS THE FOOD BEFORE
IT ENTERS THE STOMACH.

CHEMICAL DIGESTION IS AT WORK.

NOW IT'S BEEN 25 MINUTES.

THE FRUIT'S PIT CANNOT BE
DISSOLVED AND IT'S TOO LARGE TO

PASS THROUGH THE DIGESTIVE
TRACT.

[MUSIC]

DYLAN: SO, NOW THE BIRD HAS
DIGESTED THE PULP AND SKIN.

THE PIT COMES BACK OUT THE WAY
IT CAME.

THE QUETZAL IS DOING ITS PART TO
REPLENISH THE FOREST, DISPERSING

THE SEEDS OF THE TREES THAT FEED
IT.

LIKE A GARDENER, THE QUETZAL
REPLANTS THE FOREST.

THE EXACT MOVEMENTS OF THIS BIRD
HAVE ONLY RECENTLY BEEN

DISCOVERED.

[MUSIC CONTINUES]

DYLAN: LIKE MANY OF THE PLANET'S
RAREST LIVING TREASURES, THE

QUETZAL AND ITS UNIQUELY EXOTIC
ENVIRONMENT REQUIRE CARE AND

PROTECTION TO ENSURE THEIR
BRILLIANT ADDITION TO THE WILD

IS NEVER LOST.

COMING UP, COMPETITION IS HIGH
TO BE THE SAVANNA'S MOST

CELEBRATED SOLOIST.

AND WE'LL TAKE A CLOSER LOOK AT
A LIVING LATIN LEGEND.

PLUS, PRETTY PLUMAGE IS NOTHING
COMPARED TO THIS BOLDLY-COLORED

BILL.

WHEN "EARTH ODYSSEY" RETURNS.

.

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

[MUSIC]

DYLAN: THE SOUNDTRACK TO THE
AFRICAN SAVANNA IS A DIVERSE,

BUT SINGULAR TUNE; BIRD SONG.

FIRST, A VERY DISTINCTIVE ONE IN
TWO CLEAR BEATS.

THE BLACK-BELLIED BUSTARD.

[MUSIC AND BIRD SONG]

DYLAN: EVEN THIS YOUNG IMPALA IS
IMPRESSED.

AND THEN THERE'S THE SONG OF THE
FRANCOLIN, WHICH IS MORE LIKE A

SHOUT THAN A SONG.

AS THERE ARE NEARLY 300 SPECIES
OF BIRDS IN THE SAVANNA AND THEY

OFTEN SING AT THE SAME TIME, IT
GIVES THE IMPRESSION THAT

EVERYONE IS SINGING THEIR OWN
VERSE AS PART OF A CAPTIVATING

CHOIR.

THE TRUTH IS FAR MORE
STRAIGHTFORWARD; IT'S MATING

SEASON.

AND ALL THESE BIRDS ARE LOOKING
FOR A PARTNER.

FOR WOODLAND KINGFISHERS, WHEN
THE PAIR HAVE GOT TOGETHER,

IT'S IMPOSSIBLE TO TELL
THE MALE FROM THE FEMALE.

ON THE OTHER HAND, IT'S EASIER
WITH THE LESSER MASKED WEAVER

WHEN THEY FIND A MATE.

THE MALE IS DISTINGUISHED BY ITS
CHARACTERISTIC BLACK MASK.

[MUSIC AND BIRD SOUNDS CONTINUE

DYLAN: FOR THE WEAVERS, THIS
TIME OF YEAR IS ALL ABOUT

PREPARING FOR NEWBORNS.

THE MALES GATHER IN DOZENS, IF
NOT HUNDREDS, IN THE SAME TREE

TO BUILD THEIR NESTS DESPITE THE
RIVALRY BETWEEN THEM.

BECAUSE WITH THESE BIRDS, THE
FEMALE DOESN'T CHOOSE A PARTNER,

SHE CHOOSES A NEST.

AND IT'S THE BUILDER OF THE BEST
NEST WHO WINS THE FEMALE'S

AFFECTION.

[MUSIC AND BIRD SOUNDS CONTINUE

DYLAN: YOU CAN SEE WHY THE MALES
CHOOSE THIS TIME OF YEAR.

IT PROVIDES THE BIRDS WITH
PRECIOUS RAW MATERIAL.

LONG STEMS OF GREEN GRASS WHOSE
FLEXIBILITY IS JUST RIGHT FOR

WEAVING.

[MUSIC AND BIRD SOUNDS CONTINUE

DYLAN: THEIR EXPERT TECHNIQUE
NEVER CHANGES AND BEGINS WITH

THE CHOICE OF A BRANCH ALWAYS
POINTING TOWARDS THE GROUND.

THE BIRD CLEARS AWAY THE LEAVES
AND STARTS ON THE BUILDING OF A

HOOP...

WHOSE LOWER PART WILL SERVE AS
A PERCH THROUGHOUT THE WORK.

THOSE BIRDS WHO FINISH BUILDING
PLACE THEMSELVES AT THE ENTRANCE

OF THE NEST AND START TO BEAT
THEIR WINGS FURIOUSLY.

THIS IS A SIGNAL TO FEMALES THAT
THERE'S A HOME TO VISIT AND AN

AVAILABLE PARTNER.

THE GO-AWAY-BIRD IS ANOTHER
UNIQUE ADDITION TO THE WILD.

AS IT HAS TO DRINK FREQUENTLY,
THE GO-AWAY BIRD SPENDS ITS DAYS

BY THE WATER ALONG WITH THE
FISH-EATING BIRDS, AS WELL AS A

FEW THAT PREFER ALTERNATIVE
EATS.

CONTRARY TO ITS NAME, THE
WOODLAND KINGFISHER IS AN

INSECTIVORE; A KINGFISHER THAT
DOESN'T FISH.

IT'S ONE OF NATURE'S MANY
EXAMPLES THAT YOU CAN'T JUDGE A

BOOK, OR A BIRD, BY ITS COVER.

AFTER THE BREAK, COLOR AND
WONDER DEFINE THIS RARE BIRD OF

BEAUTY.

AND A LONG-LEGGED SPECIES IS
LOOKING FOR LOVE IN THE AFRICAN

WILD.

DON'T GO ANYWHERE, "EARTH
ODYSSEY" WILL BE RIGHT BACK.

.

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

[MUSIC]

DYLAN: CLOUD FORESTS ARE A WEIRD
TYPE OF RAINFOREST FOUND IN

TROPICAL AREAS WHERE MIST AND
FOG ENGULF FOREST CANOPIES

YEAR-AROUND.

THE PLANTS AND TREES RECEIVE
NEAR CONSTANT MOISTURE DIRECTLY

FROM THE CLOUDS, ALLOWING THEM
TO TAKE IN AS MUCH WATER AS

POSSIBLE.

THIS HYPERHYDRATION ATTRACTS ALL
TYPES OF SPECIES AND ANIMALS

INCLUDING ONE OF THE RAREST
BIRDS IN THE WORLD.

THE CLOUD FORESTS OF COSTA RICA
ARE ONE OF THE MOST IMPRESSIVE

AND VIBRANT EXAMPLES OF
BIODIVERSITY ON THE PLANET.

[MUSIC AND BIRD SOUNDS]

DYLAN: AND IN THE HEART OF THESE
FORESTS LIVES A BIRD OF MYTH AND

LEGEND...

... THE MAGNIFICENT QUETZAL.

THE BIRD IS CLASSIFIED AS A NEAR
THREATENED SPECIES, ON THE RED

LIST OF THE INTERNATIONAL UNION
FOR THE CONSERVATION OF NATURE.

[MUSIC CONTINUES]

DYLAN: THE REMARKABLE TAIL
FEATHERS CAN FORM A TRAIN NEARLY

3 FEET LONG.

THESE ONLY OCCUR ON ADULT MALES.

THOSE LESS THAN 3 YEARS OLD MUST
WAIT.

THE FEMALES ARE MORE DISCREET.

ALTHOUGH THEIR PLUMAGE IS LESS
VARIED, IT IS STILL BEAUTIFULLY

IRIDESCENT.

LIKE THE SCALES ON THE WINGS OF
A BUTTERFLY, THE FEATHERS OF THE

QUETZAL CHANGE COLOR DEPENDING
UPON THE LIGHT AND THE ANGLE

FROM WHICH THEY ARE OBSERVED.

BEING AN UNUSUAL BIRD, IT'S NO
SURPRISE THE QUETZAL HAS SOME

UNUSUAL BEHAVIORS.

HERE'S THE PROOF.

THESE BIRDS MIGRATE, BUT
VERTICALLY.

[MUSIC CONTINUES]

DYLAN: NORMALLY LIVING AT AN
ALTITUDE OF ALMOST 4,000 FEET,

EVERY YEAR THEY FLY UP TO ONE
AND A HALF MILES TO REPRODUCE IN

THE CLOUD FOREST.

THIS SEASONAL EVENT IS RELATED
TO THE FRUITING OF THE SPECIES

THAT IT EATS.

THERE ARE ABOUT 40 TYPES OF
FRUITING TREES ON ITS MENU.

AND THE AGUACATILLO, A TYPE OF
WILD AVOCADO, IS ONE OF ITS

FAVORITES.

THESE TREES ARE ASSOCIATED WITH
ANOTHER UNUSUAL CHARACTERISTIC

OF THIS BIRD; ITS FEEDING
HABITS.

WHEN EATING AVOCADOS, THE
QUETZAL USES A VERY ORIGINAL

FEEDING METHOD; IT GRABS ITS
FOOD WHILE IN FLIGHT.

AND WITH ITS BEAK WIDE OPEN, IT
GRABS THE FRUIT AND RIPS IT FROM

THE TREE.

MISSION ACCOMPLISHED.

BUT WHAT HAPPENS NEXT IS EVEN
MORE PECULIAR.

NO CHEWING, NO TEARING;

THE SPOILS ARE SWALLOWED WHOLE.

THE AVOCADOS VARY IN SIZE AND
THE SHREWD EYE OF THE QUETZAL IS

ATTRACTED TO THE LARGEST FRUITS.

[MUSIC CONTINUES]

DYLAN: ITS MANDIBLES, WHICH FORM
THE BEAK, AND ITS CLAVICLES,

CALLED THE FURCULA IN BIRDS, ARE
HIGHLY FLEXIBLE.

THIS ALLOWS THE QUETZAL TO
SWALLOW PARTICULARLY LARGE

FRUITS.

YET IN SPITE OF ALL ITS EFFORTS,
CERTAIN DRUPES ARE JUST TOO

LARGE TO SWALLOW.

EVEN FOR THESE EXPERT EATERS,
SOMETIMES THE EYES ARE BIGGER

THAN THE STOMACH.

WHEN WE COME BACK, WE'LL SEE ONE
OF THE WILD'S MOST COLORFUL

COMMUNITIES.

STAY TUNED FOR MORE "EARTH
ODYSSEY."

.

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

[MUSIC]

DYLAN: IN NATURE, THERE ARE VERY
FEW ANIMALS THAT HAVE AS VARIED

COLOR SCHEMES AS BIRDS.

SOME ARE COMPLETELY WHITE LIKE
THESE CATTLE EGRETS.

WHILE OTHERS HAVE BRIGHT COLORS
LIKE THE RED BREAST OF THE

GROUND HORNBILL THAT CONTRASTS
WITH THE DEEP BLACK OF ITS

PLUMAGE.

TO BEGIN WITH, ALL FEATHERS ARE
WHITE.

BUT OVER TIME, A COATING OF
MELANIN GIVES BIRDS LIKE THE

LESSER GRAY SHRIKE,

THE FORKED DRONGO,

AND THE STARLING THEIR
PATENTED BLACK PIGMENT.

[BIRDS SOUNDS]

THE SAME IS TRUE FOR THE PLUMAGE
OF SADDLE-BILLED STORKS.

THIS LARGE BIRD MEASURES ALMOST
5 FEET TALL AND THE MALE AND

FEMALE ARE ALMOST IDENTICAL.

BUT TWO DETAILS SHOW THAT THIS
IS A MALE.

FIRST, ITS EYE IS BLACK; WHEREAS
IN THE FEMALE, THE EYE IS

YELLOW.

ALSO, THE TWO LITTLE SHREDS OF
YELLOW SKIN HANGING FROM THE

BASE OF HIS BEAK INDICATE HE IS
IN THE REPRODUCTIVE PERIOD.

BUT IT'S NOT JUST PIGMENTS THAT
GIVE BIRDS THEIR BEAUTIFUL

COLORS.

SOMETIMES IT CAN BE A TRICK OF
THE LIGHT.

WITH BEE-EATERS, IT'S OFTEN A
COMBINATION OF BOTH.

LIKE MANY BIRDS, WHEN THEY'RE
YOUNG, SOUTHERN CARMINE

BEE-EATERS HAVE DULLER PLUMAGE.

IT'S ONLY THE ADULTS THAT HAVE
THIS LONG TAIL AND VIBRANT

COLORS.

BEE-EATERS HAVE DIFFERENT
PLUMAGES ACCORDING TO THE

SPECIES.

THE WHITE-FRONTED BEE-EATER HAS
A GREEN BACK, YELLOW BELLY AND A

RED THROAT.

WHEREAS THE EUROPEAN BEE-EATER,
WHICH WINTERS IN AFRICA, HAS A

BLUE BELLY, ITS THROAT IS
YELLOW, AND ITS BACK GOLDEN.

WHILE THEY MAY LOOK DIFFERENT,
ALL BEE-EATERS HAVE THE SAME

HUNTING TECHNIQUE; THEY LAND ON
A BRANCH TO OBSERVE INSECTS

PASSING AROUND THEM.

AND WHEN THEY HAVE LOCATED PREY,
THEY LAUNCH AN ATTACK, TRYING TO

CATCH THE INSECTS ON THE WING.

IF THERE ARE A LOT OF BEETLES IN
ONE PLACE, IT SUGGESTS IT'S A

GOOD HUNTING GROUND.

ONE BIRD MAKES SEVERAL HUNDRED
FLIGHTS A DAY.

IT'S THOUGHT THAT ONLY ABOUT 1
IN 3 IS PRODUCTIVE.

BEES AND WASPS MAKE UP MOST OF
THE CATCH.

ONCE BACK ON ITS PERCH, THIS
LITTLE BEE-EATER SHAKES THE

INSECT VIGOROUSLY TO GET RID OF
ITS VENOM.

THIS SPECIES IS NOT ONLY THE
SMALLEST OF ALL THE BEE-EATERS,

IT'S ALSO THE ONLY ONE TO NEST
ALONE.

OTHER BEE-EATERS NEST IN
COLONIES LIKE THIS, THE

WHITE-FRONTED BEE-EATER.

WHEN THEY NEST TOGETHER, THEY
PREFER TO CHOOSE RIVERBEDS.

OR MORE PRECISELY, SLOPING
RIVERBANKS.

THE BIRDS ARE HARD AT WORK,
BUILDING THIS COLONY THAT WILL

NUMBER ABOUT 20 NESTS.

ONCE THEY'VE CHOSEN THE PERFECT
SPOT, BEE-EATERS DIG WITH THEIR

BEAKS, SUPPORTING THEMSELVES ON
THEIR WINGS WHILE PUSHING THE

RUBBLE OUT WITH THEIR FEET.

BOTH MALES AND FEMALES WILL TAKE
PART IN BUILDING THE NEST.

BUT AS THE OPENING IS NARROW,
THEY TAKE TURNS, WORKING IN

RELAYS, WHICH EXPLAINS THIS
CONSTANT ACTIVITY.

IN ORDER TO PREVENT FLOODING
FROM RAINWATER, THE HOLES ARE

DUG SLOPING GENTLY UPWARDS.

AS AN EXTRA PRECAUTION, THE
CHAMBER WHERE THE EGGS WILL BE

LAID IS A FEW FEET AWAY FROM THE
TUNNEL'S ENTRANCE.

THIS WILL KEEP THE EGGS AND
CHICKS OUT OF THE REACH OF

BABOONS' HANDS AND STORKS'
BEAKS, ENSURING EVERY MEMBER OF

THE FLOCK CAN THRIVE IN THE
UNPREDICTABLE WILD.

EVERY CLASS OF CREATURES BRINGS
THEIR OWN STYLE TO THE ANIMAL

KINGDOM AND FEW HAVE THE VARIETY
OF SHAPES AND COLORS THAT BIRDS

DO.

FROM CITY DWELLING SURVIVALISTS
LIKE PIGEONS AND PARAKEETS, TO

RARE, EXOTIC STANDOUTS LIKE THE
QUETZAL, THE BEAUTY AND

ADAPTABILITY OF BIRDS ARE ON
FULL DISPLAY FOR US TO

APPRECIATE ALL ACROSS THE
PLANET.

THANKS FOR COMING ALONG ON
TODAY'S AVIAN ADVENTURE.

WE'LL SEE YOU NEXT TIME ON
"EARTH ODYSSEY."
