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 THERE, I'M DYLAN
DREYER, AND WE'RE OFF TO

ENCOUNTER EARTH'S MOST
EXTRAORDINARY ANIMALS RIGHT HERE

ON "EARTH ODYSSEY".

TODAY, WE'RE MEETING ANIMALS UP
CLOSE TO SEE THE SUPER SENSES

THAT ARE CRUCIAL TO SURVIVAL,
LIKE THIS FEATHERED FORAGER WHO

ALWAYS KEEPS ITS EYES ON THE
PRIZE.

AND THE TINIEST TOT OF THE TROOP
IS TUNED IN TO THE SOUNDS OF THE

WILD.

PLUS, WE'LL MEET A BIRD WITH A
BILL YOU CAN BARELY MISS.

BUT FIRST, EVEN THE BABIES OF
THIS SPECIES LOVE TO SHOW OFF

THEIR BIG PERSONALITY.

ALL OF THIS AND MORE COMING UP
ON "EARTH ODYSSEY".

[MUSIC]

AS WE STUDY ANIMALS IN THE
WILD, ONE OF THE MOST PROMINENT

OBSERVATIONS IS THEIR SUPER
SENSE.

PREY AND PREDATOR ALIKE HAVE
ASTOUNDING CAPABILITIES WHEN IT

COMES TO SIGHT, SMELL, HEARING,
AND BEYOND.

THESE SUPER SENSES CAN BE SEEN
ON FULL DISPLAY IN ALMOST EVERY

HABITAT ON EARTH.

EAGLES AND HAWKS ARE ABLE TO
SPOT A MEAL MORE THAN A MILE

AWAY WITH THEIR SHARP EYES.

POLAR BEARS CAN SMELL THROUGH
THICK SNOW FOR A CATCH.

BUT WHEN IT COMES TO HEARING,
ONE OF THE BEST IN THE BUSINESS

IS ALSO THE BIGGEST.

TAKE A LOOK.

MOVING THROUGH THE MARSHY
GRASSES, A THUNDERING PARADE CAN

BE HEARD AND FELT AS EASILY AS
IT CAN BE SEEN.

THESE ARE AFRICAN ELEPHANTS, THE
LARGEST LAND ANIMAL ON THE

PLANET.

THOUGH THEIR SUPER SIZE IS
ICONIC, IT'S THEIR HEARING THAT

IS THEIR BEST ATTRIBUTE.

THANKS TO THEIR ENORMOUS EAR
FLAPS, THEY PICK UP EVERY SOUND

WITH EXTREME PRECISION.

THEIR HEARING IS SO EFFECTIVE,
THEY CAN PICK UP SOUNDS AT ONLY

FIVE HERTZ.

THE AVERAGE HUMAN CAN'T HEAR
ANYTHING BELOW 20.

BUT THEIR EARS AREN'T THEIR ONLY
SOUND TOOLS.

ELEPHANTS CAN ALSO HEAR IN A
STRANGE WAY, THROUGH THEIR FEET.

THEY CAN PICK UP ACOUSTIC
SOUNDWAVES ON THE GROUND'S

SURFACE FROM UP TO A MILE AWAY.

IT SEEMS EARTH'S BIGGEST ANIMALS
DEVELOP THE MOST PECULIAR

SENSORY TRAITS.

IT WOULD BE EASY TO ASSUME THAT
ELEPHANTS HAVE GREAT VISION

BECAUSE THEY TOWER OVER ALMOST
EVERYTHING.

HOWEVER, SIGHT IS A SENSE
ELEPHANTS STRUGGLE WITH.

WHILE WE MAY FIND IT EASY TO
SPOT THEM AMONG THESE TALL

GRASSES, ELEPHANTS RELY MORE ON
THEIR TRUMPETING SOUNDS, HUGE

EARS, AND TRUNKS TO FIND ONE
ANOTHER.

BUT EVEN THAT CAN PROVE
DIFFICULT SOMETIMES.

THIS MOTHER HAS LOST HER CALF.

SHE SEARCHES THE TALL GRASSES BY
THE RIVER FOR ANY SIGNS.

SHE CROSSES INTO THE MIDDLE OF
THE WATER FOR A BETTER VIEW, BUT

STILL NOTHING.

THIS TERRAPIN MAY HAVE A CLUE.

FOUND IT.

THE BABY ELEPHANT IS ONLY A FEW
HUNDRED YARDS AWAY FROM ITS

MOTHER.

EVEN IF THE REEDS WEREN'T THERE,
THEY'RE TOO FAR AWAY FOR EITHER

TO SEE EACH OTHER, SO IT'S UP TO
THE LITTLE ONE TO MAKE ITS WAY

OUT OF THE RIVER AND BACK TO
MORE FAMILIAR TERRITORY.

BUT THAT TASK IS EASIER SAID
THAN DONE FOR THIS MINI-GIANT.

THE SWIMMING IS TIRING, AND NOT
FAR AWAY LIES ANOTHER POTENTIAL

PROBLEM.

A HERD OF HIPPOS HAS CLAIMED A
PART OF THE RIVER, AND THEY

DON'T LIKE INTRUDERS.

BUT THIS LITTLE ELEPHANT IS
DETERMINED AND WON'T BE

INTIMIDATED BY THIS AQUATIC
ARMY.

IN FACT, HE TAKES THEM HEAD, OR
SHALL WE SAY, TRUNK, ON.

PHEW, SAFELY THROUGH.

THE MASSIVE MALE HIPPO COULD
HAVE EASILY MADE THE SITUATION

MORE DANGEROUS.

HOWEVER, IN THIS INSTANCE, PEACE
PREVAILS.

WHILE THE SEARCH FOR MOM
CONTINUES, THE HARDEST PART IS

OVER, AND THIS YOUNG CALF CAN
SOON REST SAFELY BACK HOME.

COMING UP, WE'LL MEET A BEEFY
BIRD ON NEIGHBORHOOD WATCH.

AND A TIGHT-KNIT TROOP THAT
LOVES A BIT OF ROUGH-AND-TUMBLE.

[MONKEYS SCREECHING]

THEN WE'LL SEE HOW THIS AGILE
AVIAN IS DIVING INTO LUNCH BEAK

FIRST WHEN "EARTH ODYSSEY"
RETURNS.

.

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

DYLAN: AFRICA IS HOME TO SOME
OF THE WORLD'S BIGGEST ANIMALS,

AND THE BIRDS HERE CARRY ON THAT
TRADITION.

THIS IS AN OSTRICH, THE LARGEST
BIRD ON EARTH.

YET EVEN WITH THAT IMPRESSIVE
TITLE, THEY'RE STILL ALWAYS ON

THE LOOKOUT FOR TERRESTRIAL
PREDATORS.

THEIR MAIN FOE, CHEETAHS, WHICH
MEANS ANY ESCAPE REQUIRES

SERIOUS SPEED.

BUT OSTRICHES CAN HOLD THEIR OWN
IN A RACE.

THEIR LONG LEGS ARE CAPPED OFF
WITH TWO MASSIVE TOES.

THE LONGEST HAS A CLAW ON THE
END, WHICH THE OSTRICH USES TO

DIG WHILE FORAGING OR TO DEFEND
ITSELF.

AND IT'S A FORMIDABLE WEAPON.

WHILE THEY MAY BE FAST, THE REAL
DANGER IS BEING CAUGHT

OFF-GUARD, AND THAT'S WHERE A
COUPLE SUPER SENSES COME INTO

PLAY.

OSTRICHES SEE AND HEAR EXTREMELY
WELL.

THEY HEAR THROUGH TWO EAR-LIKE
ORIFICES THAT POINT BACKWARDS,

ATTUNED TO THE SOUNDS AROUND
THEM.

THEY ALSO HAVE EXCEPTIONAL
EYESIGHT, ABLE TO SPOT MOVEMENTS

UP TO A MILE-AND-A-HALF AWAY.

THEIR HEIGHT MAKES AN OSTRICH'S
EYESIGHT EVEN MORE EFFECTIVE,

SURVEYING THE LAND FROM UP TO
NINE FEET OFF THE GROUND

AT FULL STRETCH.

AND WE HUMANS AREN'T THE ONLY
ONES WHO HAVE TAKEN NOTICE OF

THE OSTRICH'S TALENTS.

ZEBRAS WILL OFTEN STAND BY
OSTRICHES FOR SAFETY, KNOWING

THEIR FEATHERED FRIENDS WILL
SENSE DANGER FAR QUICKER THAN

THEY WOULD.

HOWEVER, ZEBRAS THEMSELVES HAVE
EXCELLENT VISION, BETTER THAN

MOST OTHER MAMMALS IN THE
REGION, APART FROM THE GIRAFFE.

BUT ITS EYES ARE ON THE SIDE,
LIMITING THEIR FIELD OF VISION

AND REQUIRING THEM TO CONSTANTLY
TURN THEIR HEADS.

WHEN AN OSTRICH ISN'T AROUND,
THEY RESORT TO A FAR SIMPLER

DEFENSE TACTIC, STICKING
TOGETHER.

BUT FOR NOW, THEY CAN RELY ON
THEIR BIG BIRD BODYGUARD.

FOR MOST BIRDS, THEIR EYES ARE
PROPORTIONATELY MUCH LARGER THAN

OTHER CLASSES OF ANIMALS.

THIS IS TRUE FOR LARGER BIRDS,
LIKE THE KORI BUSTARD...

...AND SMALLER ONES, LIKE THIS
BULBUL.

THE SAME IS TRUE FOR THE
RED-BILLED QUELEA...

[BIRD CHIRPING]

...AND THE WEAVERS, GIVING US
AN IDEA OF HOW IMPORTANT SIGHT

IS TO THE SUCCESS OF ALMOST
EVERY BIRD SPECIES.

WHEN WE COME BACK, LOOKS LIKE
THIS BABOON HAS PICKED UP A TAIL

ON HIS MORNING STROLL.

AND ONE EXOTIC BIRD KNOWN FOR
ITS COLORFUL WAY OF CATCHING

FISH.

THIS AND MORE NEXT ON "EARTH
ODYSSEY".

.

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

DYLAN: MANY ANIMALS IN THE WILD
RELY HEAVILY ON A SINGLE SENSE

TO GIVE THEM THEIR BEST CHANCE
AT SURVIVAL; HOWEVER, FOR

OTHERS, SUCCESS IN THE WILD IS
ABOUT THEIR FULL COMPLEMENT OF

SENSES WORKING TOGETHER, USING
THE FULL PACKAGE IN ORDER TO

DEFEND THEMSELVES, FIND FOOD,
AND SENSE DANGER.

AND THERE ARE FEW BETTER
EXAMPLES THAN OUR CLOSEST ANIMAL

ACQUAINTANCES, PRIMATES.

OFTEN TIMES YOU ONLY HAVE TO
OBSERVE ANIMALS FOR A FEW

MOMENTS TO UNDERSTAND HOW
EFFECTIVELY THEY USE THEIR

SIGHT, SMELL, AND HEARING.

BIG EARS, LIKE ON THIS YOUNG
BABOON, USUALLY MEAN ONE

THING...

...IMPRESSIVE HEARING.

HOWEVER, THERE'S A BIT MORE TO
BABOON EARS THAN MEETS THE EYE.

THEIR SIZE IS EXTREMELY
PROMINENT ON THIS YOUNG MALE;

HOWEVER, AS HE GROWS, HIS EARS
DO NOT KEEP UP.

WHEN THEY BECOME ADULTS, THEIR
EARS BECOME LESS IMPOSING,

REVEALING THAT HEARING IS NOT
THEIR TRUE SUPER SENSE.

INSTEAD, IT'S THEIR EYESIGHT.

THEIR EYES ARE NOT PARTICULARLY
BIG, BUT THEY'RE PLACED AT THE

FRONT OF THE HEAD, WHICH GIVES
THEM VERY GOOD BINOCULAR VISION.

THESE MONKEYS CAN SEE A LONG
WAY, ABLE TO DETECT A MOTIONLESS

PREDATOR MORE THAN 1,500 FEET
AWAY; HOWEVER, BABOONS SPEND

MOST OF THEIR LIFE ON THE
GROUND, WHERE THEIR EYESIGHT IS

ACTIVE ALL THE TIME.

WHETHER SEARCHING FOR FOOD OR
ENSURING THEIR SAFETY, A BABOON

ALWAYS HAS THEIR HEAD ON A
SWIVEL.

BUT SIGHT ISN'T THEIR ONLY
TALENT.

THE SIZE OF THEIR MUZZLE
SUGGESTS THAT THEY HAVE A KEEN

SENSE OF SMELL.

ITS MOST OBVIOUS USE, FINDING
AND SELECTING WHAT'S ON THE

DINNER MENU.

BEING AN OMNIVORE, THE CHOICE IS
PLENTIFUL.

BABOONS ARE HIGHLY SOCIAL AND
ACTIVE, WHICH BRINGS EVERY ONE

OF THEIR SENSES INTO PLAY.

[MONKEYS SCREECHING]

THEY'VE BEEN KNOWN TO HAVE
FIERCE ALTERCATIONS AMONG THE

TROOP; HOWEVER, TODAY IS CLEARLY
MORE ABOUT SOME GOOD

OLD-FASHIONED FUN.

[MONKEYS SCREECHING]

BABOONS ARE UNIQUE IN THAT THEY
MOVE AS A GROUP IN A VERY

DISORGANIZED MANNER.

THERE CAN BE WIDE GAPS BETWEEN
THE FIRST AND LAST OF THE GROUP

SOMETIMES UP TO 500 FEET.

TALK ABOUT STANDOFFISH.

THEY RELY ON THEIR EYESIGHT TO
KEEP WITHIN A MANAGEABLE

DISTANCE OF EACH OTHER, BUT THEY
HAVE AN EXTRA PHYSICAL TRAIT TO

HELP.

AS MONKEYS WALK, YOU CAN SEE
THAT THEIR TAIL STICKS UP FOR A

SHORT LENGTH AND THEN BENDS.

THIS CHARACTERISTIC SHAPE FOUND
IN BOTH MALES AND FEMALES

BECOMES MORE PRONOUNCED AS THEY
GET OLDER.

THIS ANATOMICAL ADAPTATION IS
THE PERFECT START TO ANY GAME OF

FOLLOW THE LEADER.

UP NEXT, WE'LL MEET THE
BRIGHTEST BEAK IN THE BUSINESS

WHEN IT COMES TO SNAPPING UP A
MEAL.

STAY TUNED FOR MORE "EARTH
ODYSSEY" AFTER THIS.

.

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

DYLAN: THE WIDE ARRAY OF
PLUMAGE AND COLORS WE SEE IN

BIRDS IS NOT ONLY CAPTIVATING TO
US, BUT A CRUCIAL SIGHT FOR SORE

EYES AMONG BIRDS THEMSELVES,
ESPECIALLY WHEN TRYING TO FIND A

MATE.

THEIR BEAUTIFUL PLUMAGE IS TO
ATTRACT AND IMPRESS, AND IT

CERTAINLY ACCOMPLISHES THAT
GOAL.

WHEREAS SOME ANIMALS, LIKE
GAZELLES, SEEM TO BE THOUSANDS

OF VERSIONS OF THE SAME SHADE
AND PATTERN, BIRDS PARADE AROUND

WITH AN AMAZING PALETTE OF
COLORS.

AND FOR MANY, THEIR SONG MATCHES
THEIR UNIQUE LOOK.

WHILE HUNDREDS OF BIRD CALLS MAY
BE HEARD ACROSS THE WILD, EACH

BIRD IS ONLY INTERESTED IN THAT
OF THEIR OWN SPECIES, A CALLING

CARD, IF YOU WILL.

[BIRD SQUAWKING]

[SQUAWKING CONTINUES]

PLACING HIMSELF OUT IN THE
OPEN, THIS WOODLAND KINGFISHER

LISTENS CLOSELY TO THE SONG OF A
RIVAL LOOKING TO MOVE IN ON HIS

TERRITORY.

BUT THERE WILL BE NO EVICTION
TODAY.

THIS HADADA IBIS IS ON THE HUNT
FOR FOOD.

UNLIKE MOST AVIANS, THIS BIRD
DOESN'T DEPEND ON ITS SIGHT.

INSTEAD, IT'S ALL ABOUT SMELL.

ITS LONG BEAK IS EQUIPPED WITH
SPECIAL SENSORS THAT DETECT

ODORS AND TELL IT JUST THE RIGHT
PLACE TO DIG FOR A DELICIOUS

MORSEL.

FOR THE YELLOW-BILLED STORK, THE
BEAK CALLS ON ANOTHER SENSE,

TOUCH.

NOT ONLY IS IT A TOOL THAT THIS
BIRD CAN USE WITH EXTREME

PRECISION, BUT IT'S EQUIPPED
WITH TACTILE SENSORS.

WHEN THE STORK FISHES, ITS BEAK
IS TRIGGERED BY REFLEX WHEN IT

FEELS A FISH.

SEEING THESE BIRDS GROOM, YOU
CAN TELL THAT THERE'S AN

ENORMOUS CONNECTION BETWEEN
SIGHT AND TOUCH.

IT'S AN IMPRESSIVE DISPLAY OF
COORDINATION AND EXPERTISE WHEN

IT COMES TO USING THEIR OWN
SUPER SENSES.

AS THE SUN SETS, THIS FRANCOLIN
PERCHES ON A BRANCH TO BE SEEN

AND HEARD ACROSS THE SAVANNAH.

[BIRD SQUAWKING]

FOR EVERY ANIMAL IN THE WILD
YOUNG AND OLD, EACH DAY IS A NEW

OPPORTUNITY TO SHOW HOW THEY'VE
MASTERED THEIR SENSES.

FOR EVERY ANIMAL ON THE PLANET
FROM AN ANT TO AN ELEPHANT AND

EVEN US HUMANS, SENSES ARE WHAT
DEFINE OUR ABILITY TO UNDERSTAND

THE WORLD AROUND US.

THEY SEND VITAL INFORMATION TO
THE BRAIN SO WE CAN MAKE

DECISIONS ABOUT WHAT IS
HAPPENING AND WHAT'S NEEDED IN

ANY GIVEN SITUATION.

WHILE EACH ORGANISM MAY RELY
MORE HEAVILY ON ONE SENSE OR

ANOTHER, IT'S CLEAR THAT THEY
ARE ALL CRUCIAL ASPECTS OF OUR

SURVIVAL, AND THAT CERTAINLY
MAKES SENSE.

WE'LL SEE YOU ON THE NEXT
EPISODE OF "EARTH ODYSSEY".
