-In southwestern Uganda, an unparalleled island of forest
covers mountaintops close to the equator.
It is known as Bwindi the Impenetrable.
Cameraman Vianet Djenguet rose to prominence through filming
endangered wildlife in Africa's forest kingdoms,
and he is here to follow the progress
of one of the rarest babies in the wild,
one of possibly only 50.
He is tracking her family with the help
of Dr. Martha Robbins of the Max Planck Institute,
who has been unlocking the secrets of this forest
for more than 20 years.
Their tracks lead to a unique habitat in its heart --
a swamp.
[ Gorilla grunting ]
The family are Bwindi mountain gorillas.
-I just spotted Nyakabara.
-1-year-old Nyakabara has a bracelet of white fur,
never seen before in mountain gorillas.
♪♪
She is the daughter of the muscular young silverback
who protects this group of 13.
They are so closely related to us,
that Vianet must wear a mask
to prevent the spread of any human diseases.
-She's just, like, piggybacking on her mother's back.
-At 16 1/2 pounds,
Nyakabara is now more than three times her birth weight.
Born a year ago, she spent her first few months
just sleeping and suckling,
attached to her mother and absolutely helpless.
Now she is alert, active,
and can ride on her mother's back to see what's going on.
Vianet is here to see if as a 1-year-old,
she is developing the vital skills to forage for herself,
but it's not going to happen in the swamp.
The food here is for experts only: thistles.
-So I'm being very careful with how I hold it
because it's covered in spines, but the gorillas love this.
It's very high in protein. -Right.
-And there's not very much of it in Bwindi.
-Oh. -But the way they eat it,
it's amazing because they take their hands
and they just go all the way up to get the leaves,
and then they fold it a bit, and they put it in their mouth.
-Oh.
-But even if you watch them chew,
they're kind of chewing like this,
and so I think it's a little bit painful for them to eat it.
-The nutrients thistles provide mean it's worth
the effort and discomfort.
Nyakabara won't be capable of this level of manual dexterity
for another 3 years.
Vianet wants to see if she can master
the more basic techniques of food manipulation.
And that's something she learns by watching her mother
handling around 100 different food plants.
[ Branch snaps ]
After around 8 months of age,
mothers become less protective of their babies,
and increasingly let them work out
how to do things for themselves.
Woody vines are an abundant food plant in the forest,
but it's the pith inside the bark that the gorillas eat.
Nyakabara learns by observation,
not instinct.
She has to find a way to get the same end result
by herself by trial and error.

Colder weather is taking over from the short summer months.
In just a few weeks, this valley could be blanketed
by snow and ice as the long, desolate winter returns.
Fela is the only white Arctic fox cub
in a litter of eight.
At just 4 months old, he is almost adult size,
but he is not an adult yet.
He still relies on his parents for food.
Fall is the cutoff time when cubs have to learn
to get the food they need to survive their first winter.
Wildlife cameraman Colin Stafford-Johnson
has decades of experience filming fox behavior
and is here to see if Fela has the resourcefulness
to come through this crucial period.
♪♪
-He purposely came downwind of me
so he could give me a really good sniff to see who I was,
and he seemed happy enough.
-Fela was born with acute senses of smell, hearing, and sight.
They are all focused on the moments
his parents return from the hunt with a potential meal.
But at this time of year, food is in short supply.
Back in the summer,
breeding seabirds provided food for Fela's family,
but there was never enough to support a whole litter,
and competition between the cubs was intense.
[ Cubs barking ]
♪♪
On average, only half will make it through their first year.
♪♪
-I'm really pretty convinced, at this stage,
that there are only four youngsters left.
I hoped that a few more might make it through.
Both parents have been rushing around this valley,
supplying food as much as they could,
but the food is coming to an end,
and they have to look after themselves.
They have to put on enough weight to condition
to get through the winter.

-The white mother of the cubs has dug up
a dead seabird she had stored.
Now she has to decide if she will give it up for her young.
A dark cub is first on the scene.
But Fela has spotted her, too.

The dark cub is begging,
but the vixen won't release the meal.
Fela flicks his tail and also calls to demand food...
...but he too is rejected.
The vixen leaves behind her hungry cubs.
This is a turning point in Fela's life.
He now has to find his own food if he is going to survive.
-This is a really dangerous time now for these young animals.
[ Fela whines ]

-Everyday, Fela must try to find out what he can eat...

The first snowfalls have arrived on the hilltops already.
It's a real sign of things to come,
and it's a real reminder of how little time Fela has.
-Freezing temperature and biting 100-mile-an-hour winds
can quickly bring hostile winter conditions.
-So alert to everything, every little movement.
He looks to be searching the rocks for, I think, spiders.
-Fela's instincts are kicking in.
♪♪
-I really came here to witness
the early days of Fela's independence,
and that's exactly what I'm seeing right now.
Of course, you think, "Well, a spider,
it's not exactly like eating a seabird or something,"
but they're full of energy, full of nutrition,
and if he gets enough of them, it'll be plenty to sustain him.
-In the remaining days of fall,
Fela will eat as much as he can to build up his fat reserves.
-It's amazing how in just a short time,
he's gone from that sort of little ball of fluff
that first emerged above the ground to the resourceful,
boisterous little character that he's become.
He'll get through into next spring,
and then it will be time to find a mate of his own.
And hopefully these valleys will resound to his calls
in the years to come.

a sanctuary that is home to over 1,000 endangered toque macaques.
Sue Gibson is a wildlife cinematographer
inspired by the complex lives of primates.
She is here to follow a high-ranking infant
in one of the troops.
A year ago, Sue filmed the alpha female's newborn son,
Jazir, on his first day.
-This is pretty unreal, actually.
I get treated with a new baby boy
who's just a few hours old.
-Now at 12 months, Jazir is triple his birth weight,
around 3 1/2 pounds.
♪♪
-I really didn't expect him to be so different.
He really does look quite a lot bigger.
He looks really healthy.
-Jazir has grown faster than other babies in the troop
thanks to his mother.
As alpha female, she eats better than the other mothers
and can provide the richest milk.
Sue is working with Dr. Wolfgang Dittus
from the Smithsonian Institute.
For almost half a century, he has studied
how rank affects success in toque macaques.
-So being the son of an alpha female has,
you know, been really good for him up until now,
but the future is still uncertain?
-He's done well, thanks to his mom,
to get this far.
Now it's going to be progressively more
his own ability to find food, his fighting ability,
getting others to help him and helping others.
All those political skills have yet to be learned by Jazir.
♪♪
-Sue is already witnessing Jazir
moving away from his mother and feeding by himself.
-This is great, Jazir foraging on his own on bugs
and berries and all those insects,
and that is a really important step.
♪♪
-He is also learning to use his bigger size
to out-muscle his smaller, lower-ranking peers.
It gives him time to learn which food is best
and where to find it.
Other frustrated infants must wait their turn as Jazir
crams extra into his cheek pouches for later.
[ Chittering ]
In macaque troops, frustration can build into tension,
and tension can easily boil over into fights.

-They've got some nasty canines,
and they are only for inflicting pain
and not to help with eating.
♪♪
-Badly wounded males can drop down
the pecking order, or even die.
It's important Jazir watches older males
to learn how to read these potentially dangerous encounters
to avoid getting hurt.
Exaggerated brow movements are used
to encourage friendly contact.
But tree shaking by the alpha male
tells others they need to keep their distance.
-That's really interesting.
That is a definite moment I've not seen before.
Jazir jumping up and down on a branch like a lot
of the dominate males do,
that's a sign of power and showing your authority,
and it's certainly good to see him going through those motions
'cause it's something that he'll be using
in the years to come.
♪♪
-Jazir is practicing skills that could enforce
his strength and power amongst his peers.
But he still needs to learn the final
and most difficult key to future success --
diplomacy.
[ Chittering ]
-He's got a long way to go yet.
He really does need to become socially independent
of his mother, meaning that he needs to form alliances
with all the males, especially.
-Like all males, Jazir must leave his family
in just a few years time to find mates in another troop.
A third of young males
don't survive this dangerous transition.
But by working with other males about to leave their troops,
Jazir can improve his chances of joining and thriving
within a new group.
-What I really want to see
is him forging those new relationships
and allies with other members of the troop,
because in a few years when he leaves,
those relationships are going to be vital for his survival.
♪♪
-As Sue continues to follow Jazir,
a change is taking place.
He's starting to develop a softer side to his character.
-It feels like when he's with
his peers and others the same age,
or even, like, the slightly older males,
there's a bit of a different vibe.
♪♪
-Jazir has joined a huddle and is grooming an older male.
This is the way male macaques nurture new friendships.
Building close ties now means he is more likely
to have their support later when it really counts.
-This is great.
This is really what I was hoping to see.
This intimacy between Jazir and the other male macaques
is real proof that he's building those essential bonds.
That's a huge step forward.
-The chances of becoming an alpha male are slim,
but the skills Jazir is mastering now
will give him the best shot at ruling his own troop
within Polonnaruwa's ancient kingdom.

The vast Mara-Serengeti ecosystem.
It's late August,
and the great migration has arrived,
1 1/2 million Wildebeest.
This is peak hunting time
for Africa's most successful land predator --
the spotted hyena.
Spotted hyena clans are ruled by the larger,
more aggressive adult females with a queen at the top.
In this clan of 60, the second adult in command is Soup.
Bisque and Chowder are her twin daughters.
They are now 11 months old.
Since birth, the sisters could rely on the protection
of their mother and the safety of the den.
Now heading toward the end of their first year,
they've grown to 55 pounds, almost half adult size.
At this stage in their development,
they must learn the skills to survive out on the savanna,
where they must explore beyond the den without their mother.
♪♪
Vianet has filmed throughout
the spotted hyena's vast geographic range.
He is tracking the cubs during this critical time
as they learn to identify opportunity from danger.
-God, they've grown up really big.
Let me see.
Different to what I left 4 months ago.
-Vianet is working with
Michigan State University scientists.
They've studied hyenas here for over 30 years
and know what dangers the sisters will face.
-Lions are definitely the main threat to Hyenas.
They're competitors.
They're all going after the same prey together.
Here, lions will actually scavenge from hyenas
slightly more often than hyenas will scavenge from lions,
and also because they are competitors,
they find cubs, find hyena cubs, they will kill hyena cubs.
-Bisque and Chowder must learn to spot
and avoid lions if they are to make it through.
In the morning, there is no sign of the sisters at the den.
They have started to explore on their own.
The clan's territory stretches over 7,000 acres,
and it takes Vianet hours to find them.
Bisque and Chowder's highly tuned senses
are vital to surviving this new world.
Sight will be their primary tool when hunting.
Scent is vital in identifying
whether they have strayed into a rival clan's territory,
and they can hear hyena calls from 3 miles away
enabling them to hone in on kills.
-I think I've heard a call up there.
-Hyenas may call in others to protect a carcass
from rival clans or lions.
But as an adult can consume
30 pounds of meat at a single sitting,
Bisque and Chowder may not find much left.
Another cub in the clan has found scraps from a kill...
...and Bisque moves in to make a challenge.
[ Cub whines ] [ Bisque growls ]

Chowder joins the fight,
so now both the sisters can chase off others
to keep hold of their meal.
-This is the first time I've seen this,
trying to crunch food, the bone.
They're becoming carnivore, for sure.
-Adult hyenas have reinforced, oversized teeth
and a crushing bite to pulverize bones.
The sisters need 4 years to develop this phenomenal weaponry
and must practice at every opportunity.
But feeding alone, they are at their most vulnerable to attack.
-They're so young, they're not quite clear yet
what danger is out there.

Right at the moment when the lion was approaching,
my heart was just pounding, thinking,
"It might come close and just maybe kill one of those cubs."
This is what they are exposed to.
-It is a threat they will have to learn to live with
day by day.
But in their first year, the twins have grown faster
and bigger than all the other cubs in the clan.

On California's rugged coast, another animal baby
must overcome the challenges of the busy human world.
♪♪
Monterey, south of San Francisco,
is one of the U.S.'s top fishing ports
and lands 10,000 tons of seafood
from the Pacific Ocean every year.
♪♪
Seafood is also in demand from southern sea otters
living along this stretch of coastline.
Once hunted to the edge of extinction,
they now number just over 3,000.
Sea otters are one of the few animals to master tool use,
smashing open mollusks and shellfish
on rocks they bring to the surface.
It's a complex lesson for any pup to master,
but to survive, they have to crack it.
It's April, and Colin,
who has been fascinated by otters since childhood,
is in Monterey following Limpet,
a 5-month-old pup
who is fast getting close to independence
and will have to master tool use soon
because he'll have to leave his mother in a matter of weeks.
-He has grown a lot!
He's certainly looking much bigger and bolder.
-Limpet now weighs 24 pounds, five times his birth weight.
Newborn sea otters can't dive or swim.
For his first few weeks,
Limpet either floated on the surface
or was towed around on his mother building
an intense one-to-one bond.
Now he is 5 months old.
He has reached a precarious stage
when his mother could send him away underprepared.
He still likes to feed on her milk,
but now she is rolling to discourage him.
If she finds him too demanding,
she could enforce weaning and abandon him
sooner rather than later.
-They always live on the edge,
and that's the thing about sea otters around here.
-Michelle Staedler of Monterey Bay Aquarium
has studied the otters here for 30 years
and understands the intense pressure the mothers are under.
-They're still lactating.
That takes a lot of energy, and then they're also
giving the pup a third of the prey items
or the food items that they bring up from the bottom.
So they're constantly giving, giving to the pup,
and they get skinnier and skinnier as time goes on,
so it's a big draw on their energy resources.
-But his next meal comes from Mom again,
a large, burrowing marine worm she dug up in the seabed.
-Yeah, every time she brings something up,
he's going and grabbing it from her.
He should now be hunting by himself.
-But there might be some hope.
April is squid season.
Millions of opalescent squid
come to spawn on this seabed here,
a massive seasonal boost for the otters
and also for fishing fleets, who work 24 hours a day.
This should be easy prey for Limpet to practice on.
-Oh! Oh.
Ah, look!
-Finally, Limpet lands a catch.
-That really proves he's getting someplace.
-Squid spawning only lasts 2 weeks.
These easy pickings will soon vanish.
To really succeed, Limpet must learn
how to find and open shellfish, a complex procedure
that his mother seemingly performs with ease.
-He's been watching his mom over the months,
watching her manipulate all those shellfish,
and that's what I want to see him do.
I want to see him dive down to get something, bring it up,
and actually open it up and eat it
because that would really meant that he's ready.
-To master tool use,
a pup first needs to identify a tool.
Sea otters scour the seabed for a suitable stone or anvil,
which they store in a pocket of skin under their arm.
Then, once they find a mollusk to open,
they bring both to the surface,
rest the rock on their belly and begin bashing.
It takes a great deal of manipulation, coordination,
force and energy
to get to the protein rich and fatty contents,
something Limpet has to get to grips with
in the next few days to prevent his mother leaving him too soon.
♪♪
But after a couple of days,
Limpet surfaces with a stone, a tool.
-That's great. Wonderful.
-All he needs is something to work on.

-He's got it!
-A mussel.
[ Stone clacking ]
-Good job.

Success. Look, he's got it open.
That's a really important thing to see.
Fantastic.
And he's not just, you know, copying his mom anymore.
He's not just sort of going through the motions.
He's actually making his own decisions,
so he really has nailed it.
-Limpet has reached a fundamental milestone
for a sea otter pup --
tool use.
Not only has he unlocked access
to a whole host of prey items in the marine environment,
but by taking some of the pressure
to find food off his mother,
he has bought himself valuable time with her.
He will have a few more weeks in her care and protection
to practice essential life skills
before he embarks on life without her.
Then he'll join other newly weaned pups
to start a new adventure on the coast of California.
