Nature (1982–…): Season 35, Episode 14 - Hotel Armadillo - full transcript

♪♪

♪♪

In the heart of Brazil

lives an animal so elusive

that until recently,

nothing was known
of its life in the wild.

The giant armadillo.

But now its life has
been caught on camera...

Nobody gets to see this.

♪♪

There's the baby.



And unique, intimate
behavior revealed.

Even their burrows have
become an attraction of their own.

This is it. This is it. This
is what we're looking for.

They're in high demand
as exclusive hotels,

where peculiar
guests check in and out

at all hours of
the day and night.

♪♪

The giant armadillo,
always digging,

is busy making room
for a forgotten world

all across Brazil's Pantanal.

♪♪



Brazil's Pantanal is a
place unlike any other.

Covering more than
80,000 square miles,

this is the largest tropical
wetland in the world.

Unlike the lands
around the Amazon,

which are covered
by high forest,

the Pantanal consists
of vast expanses

of flooded grassland,

with only here and there
a patch of dry savanna

or a stretch of trees.

Prone to intense
drought and severe floods,

this is a landscape of extremes.

A huge diversity of
species lives here...

including one of
the most secretive...

The giant armadillo.

Solitary, nocturnal,
and extremely rare,

it digs huge underground
burrows up to 20 feet deep

and spends three-quarters
of its life in them underground.

Until recently, we
knew virtually nothing

of their lives in the wild.

But Arnaud Desbiez,

the founder of the
Giant Armadillo Project,

has changed that.

When I started the
Giant Armadillo Project,

I had already been working
and living in the Pantanal

for eight years.

But during those eight years,

I had never seen
a giant armadillo.

It was a species I
really wanted to see.

Even finding signs
of giant armadillos

is extremely difficult.

But gradually, Arnaud
started to build up

a picture of their hidden world.

We couldn't leave
any stone unturned.

And little by little, yes, we
did start finding evidence.

And it was so exciting
when we got our first picture.

That was an indescribable
moment because there it was.

The species we were
working so hard to find...

We couldn't believe it.

It's so hard to believe
that this magnificent giant

is living right beside us.

It's right there.

But you don't see it.

It's May...

The start of Arnaud's
research year.

But this season's
expedition could be different.

He has used camera traps before,

but they have only
given him brief glimpses

of the animal in which
he is so interested.

Now Arnaud has
newly developed gear

that could give him
more continuous pictures

from above and below ground.

The team has found
the burrow of a female

that they've named Tracy,

in honor of the first giant
armadillo researcher,

Tracy Carter.

♪♪

The new camera rig
can record pictures

by day and by night.

It is switched on by
the tiniest movements,

and the team are hoping
that the animals themselves

will trigger recordings
that will reveal

new things about them.

There are good reasons

why giant armadillos
are so rarely seen.

Their senses of smell
and hearing are acute,

and they are exceptionally
wary of people and cameras.

The locals still
consider these animals

to be supernatural beings...

Monsters that come up
from deep within the earth.

The cameras are rigged,

but will Tracy appear
and switch them on?

♪♪

Okay, okay. Tracy is coming out.

Ah, this is beautiful.

Armadillos are one of the
most ancient of living mammals

and first appeared some
50 million years ago.

The giant species is still found

in many parts of South America,

but there are so few of them

that images like
these are truly rare.

It's a major achievement
for Arnaud and his team.

So, Tracy is investigating
her surroundings.

Scent is the key sense
for giant armadillos.

So she's sniffing
the air around her.

The burrow is her safety net,

so if anything goes wrong,

if she smells
anything out of place,

if she has any concern,

she can just run back.

Just to be able to
see this right now

is just amazing.

Wow.

Arnaud's research
is starting to suggest

something quite unexpected.

He has discovered

that the huge holes they dig

are quickly taken
over by other creatures

living in the neighborhood,

so they could be
critical to the survival

of the whole Pantanal ecosystem.

The giants dig a new
burrow about every two days

and so provide ready-made hotels

for dozens of other creatures.

And now, as Tracy checks
out to spend the night feeding,

a whole army of guests
are ready to check in.

The team has now recorded

77 different species
visiting Hotel Armadillo.

Small rodents are almost
always the first to turn up.

♪♪

It's not only the quality
of the accommodation

that attracts the lodgers.

The food is good, too,

for the newly-excavated earth
is rich with insects and roots.

Lowland tapirs are too big to
get into an armadillo burrow,

but that is not a problem

for small anteaters
called tamanduas.

They visit the vacant burrows

more frequently
than any other animal.

Tamanduas spend most
of their time up in the trees,

but they use giant armadillo
burrows as nurseries...

Safe, cool places where
they can leave a baby.

For them, a family
room in Hotel Armadillo

is perfect accommodation.

♪♪

The Giant Armadillo
Project is supported

by more than 40 zoos
and aquariums worldwide,

but it has its base at the
Baia das Pedras Ranch

in the heart of the Pantanal.

Here, Arnaud's team works out
how best to track the armadillos

and log the great
range of other animals

that make use of
the hotels they create.

The project currently
has four individual animals

under surveillance.

Each has been fitted
with a tiny transmitter

that allows Arnaud and his
team to find and then track them.

An individual can
have a home range

of over six square miles.

And in a single year,

it may excavate more
than 150 burrows.

Sometimes, old burrows
can produce a surprise.

Did you hear that?
There's an animal inside.

It's a six-banded armadillo

using the giant
armadillo burrow.

That's why we call armadillos
ecosystem engineers.

So when we say giant armadillos

provide homes for
other species, this is it.

Look. Here he is.

But it's giant armadillos

the team are searching for,

and soon, they pick up a signal

from a female they've
named Isabelle.

Isabelle is really an
armadillo that introduced us

to the giant armadillo world.

Things that we now
sometimes take for granted,

things that we know
about giant armadillos,

we learned from Isabelle.

♪♪

Isabelle's offspring, Alex,

became the first
baby giant armadillo

ever studied scientifically.

The team followed his
story for almost two years.

Through Alex, we learned a lot

about giant armadillo
parental care,

so lots of discoveries
were made.

We had no idea
that giant armadillos

and the females were
such dedicated mothers.

But then,

when Alex was still
less than 2 years old,

he was killed by a hungry puma.

So we all felt
devastated by Alex's loss.

The whole team
was very, very sad.

And on a scientific
point of view,

for the project, it
was a huge loss

because there was lots of
data we still wanted to collect.

There was still lots
of questions we had.

♪♪

The team is desperately hoping

that Isabelle will
produce another baby

so that they can
continue their research.

But the battery of Isabelle's
transmitter is running low,

so the time they have
to study her at close hand

is running out.

She's been tracked
to a fresh burrow.

Once she emerges after dark,

she'll be held in a mesh tube

While an alarm signal
alerts the waiting team.

♪♪

A t giant armadillo
Tracy's old burrow,

it's an hour before dawn.

Deep in the basement suite,

the tamanduas
are still in residence.

♪♪

Upstairs in the lobby, a
visitor is passing through.

It's a Brazilian porcupine...

A guest never recorded before

and one that brings the
list of different species to 78.

Another indication
of the Pantanal's

amazing biodiversity.

As dawn breaks,

the female tamandua
heads out to feed.

Ants and termites make up

more than 90% of their diet.

And an adult needs to consume
thousands of them every day.

But while the mother
feeds, the baby is vulnerable.

A pair of tayras have picked
up the scent of the youngster.

Baby tamanduas
are sometimes killed

by these three-feet-long
relatives of the weasel.

But these tayras have
come to Hotel Armadillo

for a different reason.

The open ground
and the soft earth

makes this an
ideal spot for mating.

The tayras move on, and
mother tamandua returns.

But the infant seems
to have been alarmed

by the scent of the predators...

and it's behaving aggressively.

Not the warmest of
"Welcome homes."

But the powerful
defensive display

has shown that the youngster
is able to fend for itself

and is now ready to leave
the safety of Hotel Armadillo.

The alarm is sounding.

Isabelle is in the trap.

Once dawn breaks, she's
transferred to a large box

and taken to a clearing.

♪♪

The Giant Armadillo
Project employs two vets

who have developed
specialized knowledge

of this rare creature.

Camila just applied
the aesthetic,

and now we have to wait.

♪♪

Arnaud has worked out

that a giant armadillo's
gestation period

is five months.

But he has no way of telling

whether or not Isabelle
is expecting a baby.

Perfect.

However, he takes the chance
to check her general health

and collect samples
of her hair and blood

and other tissues.

A Giant armadillo can weigh
an astonishing 110 pounds.

Its armor-plated skin

is made of a combination
of horn and bone.

♪♪

Flexible and strong,

it makes an adult
giant armadillo

almost predator-proof.

♪♪

Isabelle measures
about 4 feet 8 inches long,

and she's superbly
equipped for digging.

Giant armadillo front claws

can be more than 7 inches long.

They give Isabelle the ability

to rip open termite mounds

and excavate burrows
in really hard ground.

She is a living bulldozer.

♪♪

Her back feet are shovel shaped

and so efficient that,
big though she is,

she can disappear below ground

in less than 20 minutes.

Every single part
of a giant armadillo

is fascinating for Arnaud.

I'm collecting hair
off a giant armadillo.

They have tiny, little
hairs between the scales.

Yet still, so little is known

about these remarkable creatures

that every piece
of data is precious.

As Alex's mother,
Isabelle helped Arnaud

discover a great deal
about her secret world.

I know you're not
supposed to have favorites,

but we learned so much with her

and spent so much time with her.

She holds a really
special place in my heart.

As the final samples
are collected,

Isabelle starts to recover.

The armadillos
are always released

into the same burrows
where they were caught.

Because this is an animal
we've been monitoring

already for a while,

the transmitter is
gonna stop working soon.

She's losing her batteries.

So we're a little bit sad

and a little bit
emotional because I think

this is probably the last
time we see her physically

or get a chance to
put our hands on her.

So it's kind of like saying
goodbye to her now.

She's still a little unsteady
from the anesthetic.

But she'll have plenty
of time to sleep it off

once she's back underground.

Beautiful.

The team may never see
Isabelle face to face again.

♪♪

But with luck,

the new camera
traps will enable them

to monitor her
progress in detail.

One day, she may even
be seen with a new baby,

and then the work they
started with Alex can continue.

But that remains a
dream for the team...

One that sometimes
seems almost impossible.

♪♪

The Pantanal may
be rich with wildlife,

but this place is
also home to people.

The traditional way
of cattle ranching here,

however, gives wildlife
plenty of room to thrive.

Throughout the seasons,

cowboys move the
herds around the Pantanal

from pasture to pasture.

It's a system that has been
used here for over 250 years.

♪♪

The edges of the pastures

are dotted with
the termite mounds

that are crucial food stores
for the giant armadillos.

♪♪

Arnaud is also rigging
these with cameras.

♪♪

The team is hoping

the footage will
confirm their suspicion

that the armadillos
are providing something

more than accommodation
in their hotels.

Could it be that they're also
in the restaurant business?

It's 11:00 a.m.

The hottest part of
the day is approaching.

Soon, temperatures will soar
to more than 100 degrees.

But deep underground

in the basement
of Hotel Armadillo,

the baby tamandua is enjoying
a comfortable 75 degrees.

Having been alone now
for more than 12 hours,

it's very hungry.

It's not the only animal
that needs a meal.

♪♪

On the pasture near the burrow,

a family party of coatis
are looking for food.

These close relatives
of the raccoon

are also occasional
visitors to Hotel Armadillo.

♪♪

As the sun reaches
its highest point,

they head towards the
burrow and the shady forest.

They're followed closely
by a group of peccaries.

Peccaries often follow
coatis to collect the fruit

that the coatis
knock from the trees.

But today, the choicest
morsels available

are the exposed roots and
shoots around the burrow entrance.

A 65-pound peccary

is capable of causing a
lot of damage to the hotel.

♪♪

A collapsed roof would be
a disaster for any resident.

♪♪

Once they've gone,

the baby tamandua
makes its move.

It's now out on its own.

Hotel Armadillo has vacancies.

Back at the termite
mound, Arnaud is eager

to check the camera
trap for visitors.

Right on cue, at half past 7:00,

it's a big male giant armadillo.

That's crazy.

The strength of these
animals is absolutely insane.

Termite mounds are
almost as hard as cement,

and the giant armadillo
is one of the few animals

able to tear into
them like this.

But once it has
collected enough termites

with its long, sticky tongue,

it will move on.

Their powerful claws open
up big holes in the mound,

which means other animals
can benefit from the efforts

of the ecosystem's chief digger.

And here, half an hour after,

a giant anteater comes.

This is fantastic. It's perfect.

It just illustrates, you know,

how both these two
giants of the Pantanal

feed on the same resources.

♪♪

The relationship
between giant anteaters

and giant armadillos

has become increasingly
interesting to the team.

Both animals exploit
the same food sources.

So how do these
two giants co-exist?

The team is planning to
catch and radio-tag an anteater

so that its movements
can be plotted

alongside that of
the tagged armadillos.

♪♪

But first, you need
to catch your animal,

and that's best done at dusk.

It's getting a little too dark,

so we probably have maybe
five more minutes of light

where we can actually
see what we're doing.

And after that, we
have to call it a day.

The light has almost gone,

but vet Danilo suddenly spots
an anteater in the shadows.

One Giant anteater
successfully in the bag.

That was quite a run.

They have just one hour

in which to fit the anteater
with the special collar.

Once on, it will give the team a
GPS reading every 20 minutes.

Okay.

The data will then
reveal exactly how

this other giant fits into
the armadillo's world.

♪♪

Perhaps this season,
giant anteaters will appear

for the first time at
a Hotel Armadillo.

♪♪

Just three miles away,
there's a freshly dug burrow.

Beneath the surface,

giant armadillo
Tracy is stirring.

Soon, she'll head off to feed,

leaving behind another
vacant accommodation.

♪♪

A single giant armadillo

creating 15 new
hotels every month

must have a major effect

on the housing
market in the Pantanal

and benefit hundreds
of other animals.

Tracy will be vacating a
pristine, luxury establishment

with only one previous owner.

But after the damage
done by the peccaries,

her older burrow
now has something

of a budget-hotel atmosphere.

But that hasn't reduced
its popularity with visitors.

♪♪

Over the last three days,

the guestbook has
recorded agouti...

lowland tapir...

brocket deer...

bare-faced curassow...

and the giant's
pint-sized cousin,

the six-banded armadillo.

♪♪

It's now also an
important hiding place

for lizards and snakes.

And they, in turn, attract
a specialized hunter.

Red-legged
seriemas eat reptiles.

And now, Hotel Armadillo

has transformed
into Tracy's Diner.

♪♪

The total number
of different species

recorded at burrows
now stands at 79.

Whether you're a
crab-eating fox or an ocelot,

Hotel Armadillo has
something for everyone.

With so many creatures
relying on the giant armadillo,

it's not surprising that Arnaud
and his team consider the animal

to be an ambassador
for biodiversity.

♪♪

But astonishingly,
many of the local people

don't even realize
the animals exist.

So getting the message
out there in the community

is a critical part of the
Giant Armadillo Project.

How can you care about a species

you don't even know you have?

My kids at school have
projects on arctic mammals,

on the African savanna.

Somehow, we forget to celebrate

the amazing animals and
plants in our own backyard.

We're worried about
what is going to be left

for our children.

And most importantly,
will they care?

That's what's really scary.

We need to show
them the incredible role

this species plays
in the ecosystem.

I love seeing the faces of kids

when they see their first
picture of a giant armadillo.

We need these kids to grow up

and care for
biodiversity, for nature.

And the giant armadillo's future

ultimately depends
on them caring.

♪♪

There's intriguing
news from the field.

While Arnaud was
visiting the school,

project biologist Gabriel has
made a remarkable discovery.

A freshly dug armadillo burrow

with the entrance
firmly sealed up.

It was close to the spot

where the team
released Isabelle,

the female who
lost her baby, Alex.

Hotel Armadillo would
only close like this

for one sort of guest...

A baby giant armadillo.

Gabriel was able
to set up cameras,

but frustratingly, he
had to leave the area

before he could
check for images.

Seeing Isabelle
with another baby

is very important
to the project.

I want to pick up where
we left off with Alex.

There are so many
questions we still have.

Arnaud and the team are back

in their Pantanal
headquarters within 24 hours.

We just arrived last night.

And we're gonna go
straight to Isabelle's territory.

It's almost too good to
be true, It's hard to believe,

so I want to see it
with my own eyes.

♪♪

The burrow is quickly located

and the recording played back.

It is definitely Isabelle.

But where's the baby?

Okay, that night at 6:00 p.m.,

she leaves on the 31st.

And nothing has
come into the burrow.

Nothing has happened.

2nd of September...

This is where it
should happen now.

She opens the burrow.

We could not see
any image of a baby.

We both checked
together, Danilo and I.

We looked at the
camera several times.

The images show nothing.

There was no
baby giant armadillo.

Even more frustratingly,

she's moved to a new burrow.

And with her transmitter
now completely dead,

it's not possible to
follow her by radio.

I think

one of the biggest
challenges to this project

is the species itself.

Giant armadillos occur
at such low densities

and are so hard to find.

The secret, I think,
is persistence...

Never giving up...

And being in this
for the long run.

It may be a lean period
for Arnaud and the team,

but back at Hotel Armadillo,

business is booming
by day and night.

Since the team first
located Tracy in May,

she's excavated more
than 50 new burrows.

♪♪

Recent visitors caught on
camera include crab-eating fox...

ocelot...

and exactly what the
team was hoping for...

A Giant anteater.

That brings the guest
list up to 80 species.

♪♪

Baby Giant anteaters are
now appearing in the Pantanal,

clinging tightly to
their mothers' backs.

They're relatively easy to see,

making the search for
the baby giant armadillo

even more frustrating.

♪♪

The team has
traveled almost 60 miles

in the last few days.

But they didn't find a
tell-tale closed burrow.

And even more worryingly,

part of Isabelle's
territory is in flames.

Fire is a natural part
of life in the Pantanal.

It's used by the ranchers
to encourage new growth

when the rains arrive.

But with the growing
intensity of ranching,

the frequency of
fires has increased.

♪♪

And they may now
burn out of control,

destroying giant
armadillo habitat,

and therefore undermining
the part the species plays

in maintaining the wonderful
diversity of this place.

At a local level

and sometimes
international level,

it really feels
like biodiversity

does not stand a chance.

And we see this with our
own eyes all around us.

The changes, impacts,

and cascading
effects of our actions

are becoming bigger and bigger.

And seeing these vast
expanses of cash crops,

where you cannot even
hear a single bird sing...

when you see the
number of animals

killed on our roads,

you sometimes feel like a fool

for thinking you're
gonna make a difference.

You feel powerless.

It feels impossible.

♪♪

I think what keeps us going
is that we love what we do.

I love the life I lead.

I love what I do.

Sheer persistence has led Arnaud

to a burrow deep in the forest.

♪♪

This is it. This is it.

This is what we're looking for.

The burrow entrance
is firmly earthed up.

It must be Isabelle.

This is definitely the
burrow with the baby.

What's typical of it is this
sand that's on top of the burrow

and that's because
she closes the burrow...

Something she never does
unless she's protecting her baby.

So she left to go forage, and
she leaves the baby in here.

Now it should be a simple case

of setting up the remote
cameras around the sealed burrow

to capture pictures
of Isabelle's return.

But they'll have
to wait until dawn

to see the results.

Yeah, so we're
very curious to see.

We just saw footprints of
Isabelle going to the burrow,

so we believe that she's inside.

And let's just make sure that
she hasn't taken the baby out.

So we're gonna go check it out.

Here. She's coming out.

She carefully builds a ramp.

If there was a baby, this is
when it would happen here.

No, no, I don't have the baby.

There's the baby.
I have the baby.

- Do you?
- Yeah.

♪♪

Oh, this is amazing.

♪♪

Wow.

♪♪

♪♪

Yeah, she's leaving.
She's taking the baby out.

She took him out right here.

There are their tracks.

♪♪

The team's discovery of
Isabelle's baby confirms

that giant armadillos only
produce a single infant

once every three years.

So each new birth is even more
precious than anyone realized...

Not just for Giant armadillos,
but for the whole ecosystem.

♪♪

The more Arnaud
and his team discover

about this
extraordinary creature,

the better they will
be able to protect it,

and the more homes there
will be for all the other creatures

that come to stay in the
accommodations they create.

And the team's
commitment to this cause

remains unwavering.

The battle to save
the giant armadillo

is the battle to
save biodiversity.

It's all the same.

It's all together.

We have a pact
with giant armadillos,

and we are in this
for the long run.

And I really feel that we
can make a difference.

I don't think that you could
ask for much more than that.
