Remote and isolated,

0:00:370:00:40

the islands of the South Pacific have a life of their own.

0:00:400:00:44

Animals have been living in seclusion for so long,

0:00:510:00:54

they've evolved in the most curious and surprising ways.

0:00:540:00:58

But island living can carry a high price.

0:01:080:01:12

Recently, some dramatic changes have been sweeping through these strange islands.

0:01:120:01:17

At the western limits of the Pacific Ocean,

0:01:290:01:33

this is New Guinea,

0:01:330:01:35

the world's largest tropical island.

0:01:350:01:38

In these isolated jungles,

0:01:420:01:45

there are creatures only recently discovered by Westerners...

0:01:450:01:49

..and mountains that they have never visited.

0:01:530:01:56

This is the home of a mammal first seen by scientists

0:02:020:02:06

as recently as 1994.

0:02:060:02:08

Even the locals rarely see it,

0:02:130:02:16

and it has never been filmed...

0:02:160:02:19

until now.

0:02:190:02:20

RUSTLING

0:02:200:02:22

It lives in trees, but it's not a monkey.

0:02:220:02:25

Primates never made the jump across the water to this island.

0:02:250:02:29

This is a rare glimpse of an almost unknown island oddity...

0:02:430:02:47

SNORTS SOFTLY

0:02:470:02:50

..the dingiso.

0:02:500:02:52

About the size of a Labrador

0:02:560:02:59

and with bear-like features, it is - amazingly - a type of kangaroo,

0:02:590:03:03

a tree kangaroo.

0:03:030:03:06

It lives at a higher altitude than any other kangaroo,

0:03:090:03:12

hence the woolly coat.

0:03:120:03:15

Kangaroos usually feed on grass,

0:03:200:03:23

but here on New Guinea, they've climbed into the trees

0:03:230:03:26

where the greenery is more abundant.

0:03:260:03:28

So the dingiso is a kangaroo

0:03:350:03:37

which lives high in the mountains and climbs trees -

0:03:370:03:41

but then islands do have a habit of producing rather unusual animals.

0:03:410:03:46

Why?

0:03:480:03:50

Because islands offer fresh opportunities

0:03:500:03:53

to the creatures that find their way there.

0:03:530:03:55

With no monkeys in New Guinea,

0:03:550:03:57

the freedom to browse in the trees has gone to the kangaroos.

0:03:570:04:02

New Guinea is a vast island nestled close to the continental landmass of Australia.

0:04:080:04:13

As we move south and east, to smaller, more distant islands,

0:04:130:04:18

the wildlife becomes even more unusual.

0:04:180:04:21

The little-known island of New Caledonia is a small sliver of Australia

0:04:210:04:27

that was cast adrift over 60 million years ago.

0:04:270:04:31

It's home to a creature that seems to have evolved quite strangely.

0:04:370:04:41

DISTANT SQUAWKING, RUSTLING

0:04:410:04:43

It has wings, but it can't fly.

0:04:460:04:49

RUSTLING

0:04:490:04:51

THROATY GURGLES

0:04:510:04:54

It is the kagu.

0:04:580:05:01

WHISTLING TRILLS

0:05:080:05:10

FRENZIED TRILLING

0:05:150:05:18

Kagu families stick together,

0:05:210:05:23

with young from previous years helping to declare the family territory.

0:05:230:05:28

FRENZIED TRILLS

0:05:280:05:31

All intruders are chased away.

0:05:340:05:36

It's the breeding season,

0:05:490:05:51

when males rekindle the flame with their life-long partners.

0:05:510:05:55

It's hard to know what the kagu is related to -

0:06:250:06:28

a heron, a rail,

0:06:280:06:30

or maybe a pigeon.

0:06:300:06:32

Its closest relative may actually be the sun-bittern of South America,

0:06:330:06:38

7,000 miles to the east.

0:06:380:06:40

She may not seem too impressed,

0:07:010:07:03

but then kagus always keep their feet very firmly on the ground.

0:07:030:07:08

Their wings are too weak to get them airborne,

0:07:140:07:17

but why fly when all the food you need is on the ground?

0:07:170:07:21

And with no large predators stalking this island,

0:07:240:07:28

there's not much cause to take flight.

0:07:280:07:30

But this life is not without its worries.

0:07:330:07:37

A newly hatched chick is hiding among the leaves.

0:07:370:07:41

As with babies the world over, getting food into mouth can be quite a challenge.

0:07:500:07:56

Perhaps slimy worms just don't appeal.

0:08:090:08:12

The chick's camouflage helps to hide it from aerial predators

0:08:130:08:18

like the New Caledonian crow.

0:08:180:08:20

CAWING

0:08:200:08:21

Fortunately, Dad's wings still have a use...

0:08:210:08:25

CAWING

0:08:250:08:27

..to help him look big and intimidating.

0:08:270:08:30

The kagu may be an island oddity,

0:08:360:08:39

but with few prowling predators reaching the Pacific's isolated islands,

0:08:390:08:43

flightless birds are more common here than anywhere else on Earth.

0:08:430:08:47

Islands are a topsy-turvy world,

0:08:510:08:53

where evolution seems to follow a different set of rules.

0:08:530:08:58

North of New Caledonia lies the Solomon Islands archipelago,

0:08:580:09:03

a scattering of a thousand tropical islands.

0:09:030:09:06

For the select few animals that arrived here,

0:09:120:09:15

these were brave, new worlds, filled with possibilities.

0:09:150:09:19

And to make the most of what they found here,

0:09:220:09:25

some adopted a whole new way of life.

0:09:250:09:28

Among the successful colonists were skinks -

0:09:310:09:35

lizards that are usually small with short legs.

0:09:350:09:39

Quite a variety live here in the Solomons,

0:09:400:09:43

but there is one in these forests that's unlike any other skink on the planet.

0:09:430:09:48

The monkey-tailed skink is up to 50 times heavier than your average skink,

0:10:100:10:15

and is the world's largest.

0:10:150:10:17

Most skinks spend their lives on the ground, but not this monster.

0:10:200:10:24

This is the only skink to possess a prehensile tail...

0:10:280:10:31

..and unlike nearly all other skinks which dine on insects,

0:10:340:10:38

this gentle giant is entirely vegetarian.

0:10:380:10:42

As in New Guinea, there are no monkeys on these islands,

0:10:470:10:51

so this skink simply filled the gap in the market and branched out.

0:10:510:10:56

It even forms social bonds with other monkey-tailed skinks,

0:10:580:11:03

a rare characteristic among reptiles of any description.

0:11:030:11:07

This skink may be an oddity, but that is exactly why it thrives here.

0:11:070:11:13

For a leaf-eater these islands are paradise.

0:11:130:11:17

For others, though, life can be a little harder.

0:11:170:11:23

Islanders only succeed by making the most of what's around them.

0:11:230:11:28

Even spiders have their uses.

0:11:280:11:31

On Santa Catalina Island in the Solomons,

0:11:360:11:39

a fisherman prepares to go fishing.

0:11:390:11:42

He seeks out a particular spider web,

0:11:470:11:50

one that is strong and intricately spun.

0:11:500:11:53

The fish he's after can't be caught on hooks -

0:12:050:12:10

their mouths are too narrow.

0:12:100:12:12

So he has to be creative.

0:12:120:12:15

No rod or reel, just a kite...

0:12:210:12:23

..and the spider silk, wound into a lure.

0:12:260:12:29

The spider-silk lure hangs below the kite,

0:12:430:12:46

flitting across the water like an insect.

0:12:460:12:48

Now he must steer the kite to where he thinks the fish are gathered.

0:12:530:12:57

Somewhere, just beneath the surface, shoals of needlefish lie in wait.

0:12:570:13:02

He keeps a close eye on the kite - if it drops, a fish is snared.

0:13:060:13:11

No hook is needed.

0:13:140:13:16

The sharp teeth and rough scales of the needlefish are tangled in the spider silk.

0:13:160:13:23

It's clever, it's effective...

0:13:340:13:37

..and many fish can be caught in this way.

0:13:380:13:42

Their ability to adapt and find food both on land and at sea

0:13:440:13:48

was crucial to the survival of the Pacific's first human colonisers.

0:13:480:13:52

But it wasn't all plain sailing -

0:13:520:13:55

the Pacific's more remote islands

0:13:550:13:58

were some of the last places on Earth to be discovered by humans.

0:13:580:14:02

And the island chain of Hawaii is the remotest of them all.

0:14:020:14:06

These islands are so hard to reach that before humans arrived,

0:14:100:14:15

only one new species of plant or animal turned up here every 35,000 years.

0:14:150:14:20

For those lucky few that made it, this was a land of milk and honey.

0:14:220:14:27

This bird's beak is perfect for sipping nectar from tubular flowers.

0:14:330:14:38

It's an 'i'iwi -

0:14:400:14:42

a long-billed honey creeper only found in Hawaii.

0:14:420:14:45

But when blown to these shores four million years ago,

0:14:450:14:49

its ancestors looked very different.

0:14:490:14:52

Those first Hawaiian honey creepers were finch-like,

0:14:540:14:57

with short bills, perhaps quite similar to this modern honey creeper, the palila.

0:14:570:15:03

Its stout bill is perfect for ripping open tough seed pods.

0:15:030:15:07

But once here, the honey creepers made the most of it,

0:15:070:15:12

evolving into a variety of birds with some very distinctive bills.

0:15:120:15:15

The Maui parrotbill has a strong, hooked beak

0:15:190:15:23

for getting at the grubs inside dead wood.

0:15:230:15:25

And then there's the 'akiapola'au,

0:15:380:15:41

with one of the most remarkable beaks of any bird.

0:15:410:15:44

Its lower mandible is straight and chisel-like

0:15:460:15:50

and can puncture the bark to drink the sap...

0:15:500:15:52

..while its upper mandible is long and curved for winkling out grubs.

0:15:550:16:00

It's as close as a bill gets to a Swiss Army penknife.

0:16:000:16:03

Amazingly, one single type of finch evolved into 58 different species

0:16:040:16:10

and all because the birds that normally fill these roles,

0:16:100:16:14

like hummingbirds and woodpeckers, never made it to these islands.

0:16:140:16:18

Landfall in the Pacific is a risky business.

0:16:250:16:28

Most islands are small, low and rather uniform,

0:16:280:16:32

with few lifestyle choices on offer.

0:16:320:16:36

But there is an archipelago that truly bucks the trend.

0:16:360:16:41

Two of the largest islands in the Pacific have everything a castaway could dream of.

0:16:440:16:50

Here lives a greater diversity of unique island creatures

0:16:590:17:03

than almost anywhere else in the South Pacific.

0:17:030:17:06

Forested valleys, turbulent rivers and glacier-topped peaks...

0:17:130:17:20

this is New Zealand.

0:17:200:17:22

A thousand miles long and with a mountainous spine

0:17:280:17:33

rising one-and-a-half miles above the ocean,

0:17:330:17:35

New Zealand offered a world of possibilities

0:17:350:17:38

to creatures that found their way here.

0:17:380:17:41

ROARING WATER

0:17:460:17:49

On these islands at the end of the world

0:18:450:18:48

live some unique animals.

0:18:480:18:51

WHINING CALLS

0:18:510:18:53

Alpine parrots, called "kea", after their calls.

0:18:530:18:57

WHINING CALLS

0:18:570:19:01

Living higher than any other parrots,

0:19:010:19:03

these are possibly the world's most playful birds.

0:19:030:19:06

But most of New Zealand's pioneering creatures were drawn to the forests below.

0:19:140:19:20

And here too, given the strange nature of life on Pacific islands,

0:19:200:19:24

it pays to expect the unexpected.

0:19:240:19:28

SHUFFLING

0:19:280:19:30

And the last thing you might expect to see here...

0:19:350:19:38

..is penguins.

0:19:420:19:44

These are Fiordland crested penguins,

0:19:490:19:53

named after this corner of south New Zealand, and their funky hairdo.

0:19:530:19:56

SHRILL SQUAWKING

0:19:560:19:58

They're on their daily trip to the sea.

0:20:140:20:17

Despite hanging out in the forest, they haven't lost their taste for fish.

0:20:170:20:21

So why are these woodlands so attractive to penguins?

0:20:280:20:31

Because there are no large predators here,

0:20:330:20:36

it's a safe place for bringing up baby.

0:20:360:20:39

A freshwater stream through the forest makes a handy highway

0:20:520:20:56

for a parent penguin heading home from a fishing trip with a crop full of food.

0:20:560:21:00

BUBBLING WATER

0:21:000:21:02

Born in the forest, they stay in the forest,

0:21:090:21:11

while Mum and Dad bring fresh meals straight from the ocean.

0:21:110:21:15

CHEEPING

0:21:190:21:21

WATER WHISPERING CLOSE BY

0:21:210:21:23

They can hear the waves, they can even smell the spray,

0:21:230:21:28

but they have no idea what it looks like.

0:21:280:21:29

These chicks won't have their first splash in the ocean

0:21:290:21:32

until they're three months old,

0:21:320:21:34

when they'll finally set off on their first fishing trip, alone.

0:21:340:21:38

1,500 miles from the nearest continent,

0:21:420:21:45

New Zealand is beyond the reach of most mammals.

0:21:450:21:48

Marine mammals aside, the only ones that did succeed,

0:21:500:21:55

before humans arrived, had wings.

0:21:550:21:57

Bats.

0:21:590:22:01

This is the short-tailed bat.

0:22:010:22:03

It roosts in tree cavities and comes out at night to feed.

0:22:030:22:07

So far, so normal.

0:22:070:22:10

But these bats have been living the island life far too long

0:22:100:22:13

not to have become a little "different".

0:22:130:22:17

And they're not the only ones.

0:22:170:22:20

Wetas are primitive relatives of the locust, but they can't fly.

0:22:200:22:26

Seeing an opportunity, the bats pounced.

0:22:280:22:32

After all, why waste energy hawking for insects in the sky,

0:22:340:22:38

when there is such a feast on the forest floor?

0:22:380:22:42

RUSTLING AND CHIRPING

0:22:420:22:45

New Zealand's night-time creepy-crawlies are at the mercy of these bats.

0:22:450:22:49

Some try to put up a fight...

0:22:550:22:57

..but they're no match for THIS army of predators.

0:23:010:23:04

These bats have special sheaths that protect their wings,

0:23:090:23:13

all the better to burrow through the leaves.

0:23:130:23:15

So even worms aren't safe.

0:23:210:23:23

The very first bat

0:23:340:23:36

evolved from a mouse-like mammal many millions of years ago.

0:23:360:23:40

Here on New Zealand, it seems evolution has gone into reverse.

0:23:400:23:46

And if New Zealand's bats have turned to mice,

0:23:480:23:51

what on earth has happened to the birds?

0:23:510:23:54

In these forests

0:23:560:23:58

lives a bird that is about as un-bird-like as it is possible for a bird to be.

0:23:580:24:05

It's nocturnal, though it sometimes wakes up before sunset.

0:24:090:24:14

It has whiskers so it can feel its way in the dark.

0:24:180:24:21

It's a parrot, and weighing up to four kilos, it's the world's heaviest.

0:24:280:24:33

And yes, you've guessed it - it can't fly.

0:24:400:24:43

Meet the kakapo.

0:24:460:24:49

Too heavy and short-winged to get airborne,

0:24:580:25:00

it climbs trees instead.

0:25:000:25:03

Kakapo were once one of the most successful

0:25:160:25:19

and abundant herbivores in New Zealand - the Kiwi equivalent of our rabbit.

0:25:190:25:23

In 1899, explorer Charlie Douglas wrote, "They could be caught in the moonlight

0:25:230:25:28

"by simply shaking the tree or bush

0:25:280:25:31

"until they tumbled to the ground... like shaking down apples."

0:25:310:25:34

Its favourite food is up above - the tiny seeds of the rimu tree.

0:25:510:25:57

This fruit fuels kakapo reproduction

0:25:570:25:59

and they only breed when the trees produce a bumper crop,

0:25:590:26:03

so about once every four years.

0:26:030:26:06

Kakapo breed slower than any other bird,

0:26:090:26:12

but they also live longer,

0:26:120:26:14

sometimes more than a hundred years.

0:26:140:26:18

The male's song is as peculiar as the bird itself.

0:26:230:26:26

More frog than parrot, it can be heard up to three miles away.

0:26:260:26:32

BUZZY BOOMING

0:26:320:26:34

In a breeding season, he will boom non-stop for eight hours every night

0:26:340:26:38

for up to three months.

0:26:380:26:39

BUZZY BOOMING

0:26:390:26:43

But a female will only respond if there are plenty of rimu seeds about.

0:26:430:26:48

So while these birds may nest in burrows like rabbits,

0:26:510:26:54

unfortunately, they don't breed like them.

0:26:540:26:56

And their numbers have dwindled dramatically.

0:26:560:26:59

PIERCING WHISTLING

0:26:590:27:01

Today, fewer than a hundred kakapo survive...

0:27:030:27:06

..and precious chicks receive a helping hand.

0:27:080:27:11

Captive rearing has helped raise the number of kakapo

0:27:170:27:20

from just 51 in 1995

0:27:200:27:22

to the 91 birds alive today.

0:27:220:27:25

CHIRPING

0:27:270:27:29

They used to number in the hundreds of thousands.

0:27:330:27:36

Today, their future is truly in our hands.

0:27:360:27:39

FEEBLE CHIRPING

0:27:390:27:42

So is this now an empty forest?

0:27:460:27:49

Actually, the trees are under attack like never before.

0:27:490:27:53

There's a menace lurking amongst the foliage.

0:27:530:27:57

During the day, it slumbers.

0:28:010:28:04

But under cover of darkness, an invader is revealed.

0:28:060:28:10

Bright-eyed and bushy-tailed, the mammals have finally arrived in force.

0:28:160:28:20

Australian possums.

0:28:220:28:25

Imported for their fur two centuries ago,

0:28:260:28:30

they soon reached plague proportions, stripping trees of their vegetation.

0:28:300:28:34

A war is being waged against them -

0:28:370:28:40

traps set and poison scattered.

0:28:400:28:42

And yet they are now far more numerous than the kakapo ever were.

0:28:420:28:48

A staggering 70 million possums overrun New Zealand's forests.

0:28:480:28:53

Where a bird failed, a mammal has succeeded.

0:28:560:29:00

But why? The possums were unwitting immigrants,

0:29:020:29:05

while the kakapo have lived here for millennia -

0:29:050:29:08

perfectly adapted to this forest.

0:29:080:29:10

It's an irony that is by no means unique to the kakapo and the possum.

0:29:150:29:21

Right across the Pacific, similar scenes have been unfolding.

0:29:230:29:27

Tiny islands off the coast of New Zealand

0:29:270:29:30

are the last refuge for a host of animals now vanished from the two main islands.

0:29:300:29:35

This is Stephens Island -

0:29:350:29:39

one square mile of rock protruding from the ocean.

0:29:390:29:42

It's home to a living fossil,

0:29:420:29:45

a relict, barely changed for over 100 million years.

0:29:450:29:49

The tuatara.

0:29:550:29:57

And half the world's population survive on this one island refuge.

0:29:590:30:04

During the reign of the dinosaurs,

0:30:040:30:08

the ancestors of the tuatara were everywhere.

0:30:080:30:11

They survived the cataclysm that killed off the dinosaurs,

0:30:110:30:14

but then couldn't compete with the mammals

0:30:140:30:17

and died out...

0:30:170:30:19

everywhere, except on what was then a mammal-free New Zealand.

0:30:190:30:24

Unlike mammals, tuatara live life in the slow lane.

0:30:310:30:39

Days can pass

0:30:410:30:42

when they barely move a muscle...

0:30:420:30:45

..sometimes taking just one breath an hour.

0:30:510:30:55

They feed on wetas,

0:31:040:31:06

beetles and other invertebrates...

0:31:060:31:09

..but don't appear very good at catching them.

0:31:110:31:14

Even after millions of years of practice,

0:31:180:31:21

eye-mouth co-ordination is not what it could be.

0:31:210:31:24

"Survival of the fittest" just doesn't seem to apply here.

0:31:280:31:32

The tuatara's survival, first on New Zealand, now on Stephens Island,

0:31:400:31:44

proves a point -

0:31:440:31:46

islands are pretty safe places to be, at least until invaded.

0:31:460:31:52

Fortunately for the Stephens Island tuatara,

0:31:530:31:57

it did survive a brief mammal invasion.

0:31:570:32:00

But for some of the other wildlife here,

0:32:000:32:03

the invasion was rather more...catastrophic.

0:32:030:32:06

The island had been uninhabited and largely ignored,

0:32:070:32:11

but that all changed with the construction of this lighthouse back in 1894.

0:32:110:32:17

When the newly installed keeper, a Mr Lyall,

0:32:200:32:24

found an unusual wren on the island,

0:32:240:32:27

he sent a specimen to London for identification.

0:32:270:32:32

Like many island birds, it was flightless.

0:32:320:32:35

And perhaps that's why it wasn't Mr Lyall who first discovered the bird,

0:32:370:32:42

but his four-legged companion.

0:32:420:32:45

Tibbles proved to be a very efficient specimen collector.

0:33:000:33:05

So much so, in fact,

0:33:050:33:07

that one year later, when the bird was officially declared a new species,

0:33:070:33:12

Mr Lyall had to regretfully inform the scientific community at large

0:33:120:33:16

that the species was now extinct.

0:33:160:33:20

In truth, Tibbles wasn't the only feline to blame,

0:33:230:33:27

but the ease with which the Stephens Island wren had been dispatched

0:33:270:33:31

WAS alarming.

0:33:310:33:32

The cats were removed from Stephens Island, but it was too late for the wren.

0:33:390:33:43

Now only known from a few cat-chewed museum specimens,

0:33:430:33:48

evolving to be flightless had proven fatal.

0:33:480:33:52

So it seems there is a trade-off.

0:33:560:33:57

The freedom of island life allows a species to relax its guard,

0:33:570:34:02

but that can leave it defenceless.

0:34:020:34:06

On the main islands of New Zealand,

0:34:100:34:13

similar dramas have played out time and time again.

0:34:130:34:16

Forests dominated by giant kauri trees once covered the North Island.

0:34:180:34:24

The fragments that remain look much like they have for millennia,

0:34:240:34:28

but looks can be deceiving.

0:34:280:34:31

A few centuries ago,

0:34:310:34:34

this forest echoed with the calls of strange and wonderful birds.

0:34:340:34:39

CACOPHONY OF BIRD CALLS

0:34:390:34:43

Most famous was the giant moa,

0:34:430:34:46

which looked a bit like an ostrich, but taller than an elephant.

0:34:460:34:50

And there are many more birds

0:34:500:34:52

whose haunting songs now exist here only in memory.

0:34:520:34:56

CACOPHONY OF BIRD CALLS

0:34:560:35:02

The bird recordings and recreated songs you hear now

0:35:020:35:07

are all of species that have disappeared

0:35:070:35:10

from these main-island forests.

0:35:100:35:12

We can't just blame Tibbles and his kin. Humans have brought

0:35:350:35:39

a whole range of mammalian competitors and predators to these shores.

0:35:390:35:44

Today, the people of New Zealand are making amends.

0:35:490:35:55

This is New Zealand's most famous tree -

0:36:010:36:05

Tane Mahuta, Lord of the Forest.

0:36:050:36:08

There's more wood in this kauri tree than in any other tropical tree in the world.

0:36:090:36:14

Conservationists are working hard to protect and nurture these special forests.

0:36:140:36:21

By collecting kauri seeds, they ensure that new trees can be cultivated

0:36:210:36:26

and the forest expanded into its former range.

0:36:260:36:29

Meanwhile, the animal invaders are being controlled,

0:36:290:36:34

and birds that only survived on small outlying islands

0:36:340:36:38

are now being reintroduced to these mighty forests.

0:36:380:36:41

Back in Hawaii, being the remotest of all archipelagos,

0:36:470:36:50

you might expect the unique wildlife to have fared rather better.

0:36:500:36:55

In the lowlands, there are lush coastal rainforests teeming with life.

0:36:560:37:02

But not indigenous life.

0:37:020:37:05

None of the plants or animals you see here is actually native.

0:37:050:37:11

Jackson's chameleons were brought from East Africa as exotic pets.

0:37:210:37:27

The white-rumped shama from India and the northern cardinal from North America

0:37:350:37:39

were both introduced to supplement the native bird life,

0:37:390:37:44

while the red-billed leiothrix was a cage bird imported from China.

0:37:440:37:50

And the Japanese white-eye was imported in an attempt to control insect pests.

0:37:530:37:58

Before humans, only one new species reached Hawaii every 35,000 years.

0:38:000:38:07

Now up to 50 new species turn up every year.

0:38:070:38:12

Invaders are everywhere,

0:38:180:38:21

and some have had a significant impact.

0:38:210:38:23

In an attempt to control introduced rats,

0:38:260:38:29

humans brought the Indian mongoose to Hawaii.

0:38:290:38:33

Unfortunately, no-one considered the fact that rats are nocturnal,

0:38:330:38:37

while the mongoose hunts by day,

0:38:370:38:39

so the hungry mongoose turned its attention

0:38:390:38:42

to decimating the island's unique bird life instead.

0:38:420:38:45

Thousands of species have humans to thank

0:38:490:38:51

for bringing them to islands throughout the Pacific.

0:38:510:38:54

But there's one animal that has been a valued travelling companion

0:38:540:38:58

for as long as people have sailed this ocean.

0:38:580:39:00

GRUNTING

0:39:000:39:03

Wherever people went,

0:39:040:39:06

pigs went too.

0:39:060:39:08

ALL SING

0:39:080:39:12

In Vanuatu, 1,200 miles north of New Zealand,

0:39:120:39:16

the people of Tanna Island have gathered for a festival.

0:39:160:39:20

Like an expensive car in Western culture,

0:39:210:39:24

here pigs are a symbol of wealth and status.

0:39:240:39:29

The Toka festival celebrates the end of warfare between rival clans,

0:39:320:39:38

and pigs are at the centre of it.

0:39:380:39:42

To attend, each village must bring some to the party,

0:39:420:39:46

and that's a lot of pigs.

0:39:460:39:48

PIGS SQUEAL AND GRUNT

0:39:480:39:51

Some will be butchered for a feast, others given away.

0:39:530:39:57

But to take one of these pigs home,

0:39:580:40:00

a family must agree to one day repay the debt...

0:40:000:40:03

..and it's these pig debts

0:40:050:40:07

that help strengthen the bonds between the different villages.

0:40:070:40:10

SINGING

0:40:100:40:13

Major celebrations surround the giving and receiving of these prized assets.

0:40:210:40:26

And since the Toka only occurs once every three or four years,

0:40:260:40:31

everyone jumps at the chance to dress up.

0:40:310:40:34

SINGING AND STAMPING

0:40:360:40:39

The dancing goes on for three days.

0:40:390:40:41

Each village attempts to out-dance its neighbours

0:40:460:40:49

in a display of friendly rivalry.

0:40:490:40:51

You could say this is Strictly Come Dancing, Vanuatu-style.

0:40:540:40:59

SINGING

0:40:590:41:02

DRUMS BEAT RHYTHMICALLY

0:41:050:41:09

In the past, tribal rivalry was far more serious.

0:41:160:41:21

On this island, there were precious few wild animals to hunt.

0:41:230:41:27

Pigs would have been essential protein,

0:41:300:41:33

but if they died, perhaps through disease, what else did the islanders have to eat?

0:41:330:41:39

The great-grandparents of these dancers were cannibals.

0:41:410:41:45

Life on an isolated Pacific island is eternally poised on a knife-edge.

0:42:210:42:28

Nowhere is this more apparent

0:42:280:42:30

than on the single most remote island in the Pacific -

0:42:300:42:34

Easter Island.

0:42:340:42:36

This tiny speck of land has an extraordinary story to tell,

0:42:360:42:41

with new twists turning up still to this day.

0:42:410:42:44

Just 13 miles long and 7 miles wide,

0:42:470:42:50

Easter Island rises like a fortress from the waves,

0:42:500:42:55

surrounded by thousands of miles of ocean in every direction.

0:42:550:42:59

People first arrived here less than 1,000 years ago.

0:43:150:43:19

Most of what we know about their civilisation

0:43:190:43:21

can only be pieced together from the relics that remain.

0:43:210:43:25

It is a strange and desolate place.

0:43:300:43:33

The most striking features in this bleak and windswept landscape

0:43:400:43:44

are the hundreds of giant stone statues, known as moai,

0:43:440:43:49

thought to be carved in the likeness of chiefs or ancestors.

0:43:490:43:53

It's difficult to believe that an advanced culture

0:44:000:44:03

capable of carving and erecting these monoliths

0:44:030:44:06

grew up in such a barren landscape.

0:44:060:44:08

The truth is,

0:44:080:44:10

it didn't.

0:44:100:44:12

When those first colonisers discovered Easter Island,

0:44:120:44:15

this was a paradise.

0:44:150:44:17

These empty cliffs

0:44:260:44:28

were once home to the largest seabird colonies in the South Pacific.

0:44:280:44:32

SEABIRDS CRY

0:44:320:44:34

Rich volcanic soils nourished a forest of giant palms

0:44:390:44:43

that was home to many unique species,

0:44:430:44:46

including Easter Island versions of herons, parrots, rails and owls.

0:44:460:44:52

BIRDSONG

0:44:520:44:54

Today, they are all gone.

0:44:570:44:59

SILENCE

0:44:590:45:02

The people, ultimately, didn't do much better.

0:45:030:45:08

The rise and tragic demise of the Easter Islanders,

0:45:080:45:12

the Rapa Nui, is now legendary.

0:45:120:45:16

This quarry once occupied the majority of the island's workforce,

0:45:220:45:27

thousands of people,

0:45:270:45:28

with each clan trying to carve and raise a bigger, grander figure

0:45:280:45:32

than those of their neighbours.

0:45:320:45:34

HAMMERING AND HUBBUB

0:45:340:45:37

Vast amounts of timber would have been required

0:45:520:45:55

to transport and erect the giant moai,

0:45:550:45:59

and slowly but surely, the forests vanished.

0:45:590:46:02

Eventually,

0:46:020:46:04

there was no wood left even to build boats.

0:46:040:46:07

Without fishing boats,

0:46:070:46:08

they would have been denied their main source of food,

0:46:080:46:13

and their one means of escape.

0:46:130:46:15

As resources dwindled,

0:46:160:46:18

Easter Island society descended into chaos and warfare.

0:46:180:46:23

The giant statues were pulled to the ground -

0:46:230:46:26

possibly acts of sabotage between rival clans.

0:46:260:46:31

Houses were abandoned and the foundation stones used

0:46:370:46:41

to construct fortified dwellings in caves underground.

0:46:410:46:46

Some evidence even suggests that once everything edible had been consumed,

0:46:510:46:55

the starving were driven to that most desperate of acts - cannibalism.

0:46:550:47:00

Understandably, this version of Easter Island's history remains controversial,

0:47:060:47:11

because it suggests the Rapa Nui were incredibly short-sighted.

0:47:110:47:15

As the trees dwindled, why did they do nothing about it?

0:47:150:47:19

But a new theory suggests the Rapa Nui were powerless to prevent their downfall,

0:47:210:47:27

for when they arrived on this island,

0:47:270:47:29

they were not alone.

0:47:290:47:31

Rats travelled with people to every corner of the Pacific.

0:47:330:47:36

On Easter Island, their impact may have been catastrophic.

0:47:360:47:41

Multiplying to plague proportions, they would have devoured the wild fruits,

0:47:410:47:45

the seabirds, even the nuts of the giant palms,

0:47:450:47:49

so that the trees may have stopped reproducing

0:47:490:47:51

long before the last one was felled.

0:47:510:47:54

Perhaps the fate of Easter Island was not sealed

0:47:560:47:59

by the human who felled that last tree,

0:47:590:48:02

but by the rat that ate the last palm nut.

0:48:020:48:06

Other South Pacific islands have also seen civilisations rise and fall,

0:48:130:48:18

though none have left such dramatic reminders of their passing

0:48:180:48:22

as the giant statues of the Rapa Nui.

0:48:220:48:26

Now re-erected,

0:48:290:48:30

they've come to symbolise how precarious life can be on an isolated island.

0:48:300:48:36

For this island has not been abandoned.

0:48:370:48:40

A few Rapa Nui survived, and now they're thriving once more,

0:48:410:48:45

entertaining visitors from the outside world.

0:48:450:48:48

Trees have been planted,

0:48:500:48:52

though it's too late for the unique creatures that once lived here.

0:48:520:48:56

Elsewhere, on islands throughout the Pacific, there is still time.

0:49:000:49:05

People are working hard to remove the creatures that don't belong here

0:49:050:49:09

and make space once again for the curiosities,

0:49:090:49:12

from kagus to kakapo,

0:49:120:49:14

that make the South Pacific such a uniquely wonderful world.

0:49:140:49:19

Of all the animals in this programme,

0:49:400:49:43

the dingiso was the most difficult to film.

0:49:430:49:46

It is extremely rare, and only recently discovered by Western science,

0:49:460:49:50

which is one of the reasons why the team wanted to record it on camera.

0:49:500:49:54

Their quest took them to a forbidden land guarded by a mountain tribe.

0:49:540:49:59

No-one knew what an emotional journey lay ahead.

0:50:000:50:04

They flew to Pogapa, New Guinea -

0:50:070:50:10

a village of the Moni tribe, guardians of the dingiso.

0:50:100:50:13

A meeting was called to discuss the visitors' proposal.

0:50:130:50:18

THEY SPEAK LOCAL LANGUAGE

0:50:180:50:22

To the Moni, the dingiso is an ancestral spirit.

0:50:220:50:27

Hunting it is strictly forbidden. But how would they feel about filming it?

0:50:270:50:31

Many of these people have never visited Lake Wutidi,

0:50:310:50:34

the sacred area where the dingiso lives,

0:50:340:50:37

so letting our crew go there was a big decision.

0:50:370:50:41

There were so many times that I thought, "These people are gonna walk out the door

0:50:410:50:47

"and we're gonna have to go home."

0:50:470:50:49

But eventually, we got everybody on board, and yeah,

0:50:490:50:51

I'm really glad we're over that and now we can finally get going.

0:50:510:50:55

Pilemon is a village chief who agreed to accompany the team.

0:50:550:51:00

The Moni were now really keen to help the team track down a dingiso in the wild.

0:51:040:51:08

Good morning!

0:51:090:51:12

Everyone walked at their own pace.

0:51:120:51:15

The film crew had to take things rather more slowly.

0:51:180:51:22

We've been left for dead

0:51:220:51:24

by the old ladies and the kids

0:51:240:51:26

that are carrying the generator and the cameras

0:51:260:51:29

and our tents and all the rest of the stuff that we brought!

0:51:290:51:32

The team has reached the edge of the sacred area of Wutidi.

0:51:390:51:44

From here on in, everything changes.

0:51:440:51:48

So from here, the trail gets really slippery and really dangerous,

0:51:480:51:51

so we've got to go very slow.

0:51:510:51:53

From here on out, some of the names we use change.

0:51:530:51:56

Wutidi is... We're not allowed to use that - we use the sacred name.

0:51:560:51:59

Same for the dingiso. We have to use the sacred name for the dingiso -

0:51:590:52:03

we're not allowed to use the word "dingiso" any more.

0:52:030:52:05

The team continue to climb.

0:52:050:52:07

They are now over 3,000 metres above sea level.

0:52:070:52:11

-JAMES MAIR:

-It's madness. The landscape's totally changed.

0:52:110:52:14

It's really dry and wiry and...sparse,

0:52:140:52:17

and I think this is the kind of habitat where the animal lives,

0:52:170:52:20

kind of in the much more stunted trees.

0:52:200:52:22

Finally, they reach the sacred lake. They must remember the sacred rules.

0:52:220:52:28

This is Lake Ezimoga,

0:52:280:52:31

which is the name they use in the sacred area.

0:52:310:52:34

And this is a central point

0:52:340:52:37

from which it's a good area to look for the manimomaga,

0:52:370:52:42

which is the other name for the tree kangaroo we're looking for.

0:52:420:52:46

And everyone's...

0:52:460:52:49

everyone's pretty emotional to be here.

0:52:490:52:52

Even Chief Pilemon is deeply moved.

0:52:520:52:56

-JOE YAGGI:

-This lake is one of the most important parts of the Moni culture.

0:52:560:52:59

It's a really, really big deal for these guys to come here, to see this place.

0:52:590:53:05

With base camp established,

0:53:110:53:13

the search for a dingiso begins in earnest,

0:53:130:53:17

and it's not long before Pilemon announces he's found something.

0:53:170:53:21

PILEMON SPEAKS LOCAL LANGUAGE

0:53:210:53:23

Signs on the ground suggest a dingiso was here, and the signs are fresh.

0:53:230:53:28

He's saying the creature filled a space about this big, so he was quite large,

0:53:280:53:34

and he sticks his nose in there, he's looking for worms,

0:53:340:53:38

so he sticks his nose in there

0:53:380:53:39

and he takes his claws, and pushes the soil out of the way.

0:53:390:53:42

But dingiso are supposed to eat leaves, not worms.

0:53:420:53:46

Perhaps these are the marks of a spiny anteater, or echidna.

0:53:460:53:49

Pilemon's impression of the animal reassures the team he wasn't mistaken -

0:53:490:53:54

echidnas don't climb trees.

0:53:540:53:56

It just shows how little is known about the dingiso.

0:53:560:53:59

-JAMES MAIR:

-It's really exciting to see a kind of sign that this animal exists,

0:53:590:54:04

cos it was kinda feeling a bit like a myth,

0:54:040:54:06

especially the last couple of weeks where it's taken so much to get here

0:54:060:54:09

and the chances of filming it have felt so slim,

0:54:090:54:12

but it feels like we're kind of in with a chance now, which is great!

0:54:120:54:15

But the animal itself remains elusive.

0:54:150:54:19

A week has now passed,

0:54:190:54:21

and the trackers set out in different directions to widen the search.

0:54:210:54:26

Only three of these men have ever seen a dingiso before.

0:54:340:54:39

The chances of improving on that are looking slim.

0:54:390:54:44

Village chief Pilemon has crossed to the other side of the valley.

0:54:440:54:48

The crew are ready to follow if he signals good news.

0:54:480:54:52

Next morning, bizarrely, the postman calls. It's a letter from Pilemon.

0:54:540:54:58

But it's not the news they wanted.

0:54:580:55:00

He's just requesting fresh supplies.

0:55:000:55:03

The team have all but given up hope.

0:55:030:55:06

Late that night,

0:55:090:55:10

Chief Pilemon arrives back in camp with a shocking surprise.

0:55:100:55:15

MAN SHOUTS

0:55:160:55:18

The guys from the other side of the valley have just come in,

0:55:210:55:25

and we're not sure what they're carrying yet.

0:55:250:55:27

They've just come in to... to the camp.

0:55:270:55:29

The crew fear the worst.

0:55:320:55:33

SPEAKS IN LOCAL LANGUAGE

0:55:330:55:38

He appears to be carrying a live animal.

0:55:380:55:41

This was never part of the plan.

0:55:410:55:43

Throughout the trip, the crew had tried to make it clear

0:55:430:55:47

they only wanted to film a dingiso in the wild.

0:55:470:55:50

It is a dingiso.

0:55:540:55:56

This was the very last thing any of the team wanted to witness,

0:55:560:56:00

and it was very distressing.

0:56:000:56:02

Now the team's only concern is for the animal's welfare.

0:56:030:56:06

-JAMES MAIR:

-We're gonna have to take it back with them tomorrow.

0:56:060:56:09

We can't release it here - it needs to be released in its home territory.

0:56:090:56:13

Um...so we're gonna have to keep it like this overnight -

0:56:130:56:16

it's the only way that it can be kept safe -

0:56:160:56:19

and then take it back and release it tomorrow.

0:56:190:56:22

SPEAKS IN LOCAL LANGUAGE

0:56:250:56:27

For Pilemon, the dingiso is a sacred animal.

0:56:270:56:31

So he performs a ceremony to the spirits for capturing it.

0:56:310:56:34

As soon as they can, the team set off to return the dingiso to its forest home.

0:56:490:56:53

The dingiso is so highly revered in Moni culture

0:56:590:57:03

that Pilemon wanted to share it with the outside world.

0:57:030:57:07

Strange as it seems, bringing it to the team

0:57:070:57:09

was his way of showing great respect for the animal.

0:57:090:57:13

Filming it now depends on how the dingiso behaves once it's released.

0:57:130:57:19

We're finally where the manimomaga was found.

0:57:190:57:23

I think it was literally at the tree... one of these trees just around us.

0:57:230:57:28

We're gonna release it in the jungle and see what happens.

0:57:280:57:31

To the crew's great relief,

0:57:320:57:34

the dingiso doesn't appear to be stressed or harmed in any way.

0:57:340:57:38

It bounds up a tree, and then acts as if nothing unusual has happened.

0:57:400:57:46

OK, he's started to feed a little bit, which is a great sign.

0:57:480:57:52

After all this trouble, and walking and everything,

0:57:560:58:00

it's really great just to see him chewing on a bit of food

0:58:000:58:05

and kind of half dozing and looking a lot happier.

0:58:050:58:09

There he is, where he should be, up in a tree.

0:58:090:58:13

Tree kangaroos!

0:58:130:58:16

This had been an emotional journey for the whole team.

0:58:160:58:21

Finally,

0:58:210:58:23

intimate shots of the elusive, almost mythical dingiso,

0:58:230:58:28

back home in a place that is truly a world apart.
