- [Narrator] A female western lowland gorilla.
(gorilla grumbling)
(gentle music)
And her newborn.
(gentle music)
Just moments old.
(gentle music)
(flies buzzing)
For his mother, the arrival of her young baby
is the start of a new chapter in her adult life.
(gentle music continues)
Parenthood.
(gentle music)
Her journey will be challenging,
full of excitement,
uncertainty,
and complete commitment.
(gentle music continues)
(gentle music)
There will be mistakes.
There always are.
But success for her,
and indeed for all parents,
has perhaps the greatest of consequences.
(gentle music continues)
It ensures the future of life on our planet.
(lighthearted music)
(majestic music)
(birds chirping)
(lighthearted music)
Parenthood is a journey like no other.
(lighthearted music)
The responsibility of providing constant food
and safety for offspring
can be extremely challenging.
For most, it all begins with a good home.
(lighthearted music)
A mother lion
in the grasslands of the Kalahari in Botswana.
Her 20-strong pride is ruled by her and her sisters,
who each has her own cubs.
One mighty family
who help each other through thick and thin.
(lighthearted music continues)
(cub whining)
For months, their home is scorched by 45-degree heat.
(thunder rumbling)
(thunder cracking)
But once a year, their territory is brought to life
by distant rains.
(lighthearted music)
(elephant roaring)
(elephant grumbling)
Up until now, these cubs
have had very little experience of water.
(water splashing)
So their mother will have to guide them
to get them through the (indistinct).
(lion snarling)
(cub whining)
(lion grumbling) (water splashing)
(lion snarling)
(cub squawking)
(water splashing)
(lighthearted music)
(water splashing)
Getting used to swamp living
is a vital part of their cubs' upbringing.
Because these precious waters
attract animals from miles around.
(buffaloes grumbling)
Cape Buffalo.
The smell of fresh water lures them
from the surrounding savanna.
(rhythmic music)
And they come in extraordinary numbers.
(intrepid music) (buffaloes grumbling)
A herd three miles long
and full of one-ton animals.
(singers singing in foreign language)
(rhythmic music)
(singers singing in foreign language)
- They too cannot survive without the water
at the centre of the lion's territory.
(buffaloes grumbling)
She must show her cubs that patience is their greatest ally.
(singers singing in foreign language)
(buffaloes grumbling)
Once in the swamp,
the buffaloes spread out into smaller groups.
(intrepid music)
(singers singing in foreign language)
Lionesses will take the lead in any hunt.
(apprehensive music)
But a mother here has the added pressure
of having to teach her growing cubs how to tackle giants.
(apprehensive music)
(water splashing)
(buffalo huffing)
(buffalo grumbling)
(buffalo huffing)
One swipe of its horns could kill any one of them.
(buffalo grumbling)
The cubs must watch and learn.

(lion snarling) (buffalo groaning)
The younger lions are allowed to be the first to feast.
(buffalo groaning) (flies buzzing)
Hunting giants, however, is not without its risks.
One of the pride's mothers is missing.
(lion whining)
Contact calls go unanswered.
(lion grumbling)
(lions grumbling)
(melancholy music)
(lion grumbling)
In attempting to provide food for her young,
she has been gored by a buffalo.
There is nothing the pride can do to help.
(lion grumbling)
(melancholy music continues)
(lion huffing)
With her cubs too young to hunt for themselves,
her death leaves their future uncertain.
(cub whining)
(lion huffing)
(melancholy music continues)
(cub whining)
But they don't have to face it alone.
(uplifting music)
The matriarchs will take on responsibility for them.
(lion grumbling)
In lion society, females often share the load of parenting.
(uplifting music continues)
Related adults will continue to care for the orphans
alongside their own offspring.
It'll be another year before they're fully independent.
(cubs squealing)
(lion grumbling)
In that time, they must be taught how to survive here.
(lion snarling)
(uplifting music continues)
And luckily for them, the leader of this pride
is an excellent teacher.
(suspenseful music)
(lion growling)
(bird squawking)
(lighthearted music)
Parental investment is a risky strategy for many animals,
particularly in the largest of all habitats,
the ocean.
The sheer diversity of life makes some parts of the ocean
a highly competitive environment.
(lighthearted music continues)
So the animals who choose to raise their offspring here
need to have an edge.
(lighthearted music)
Here in Indonesia, protected by the reef,
lives one of the ocean's most ingenious parents,
a female boxer crab.
(lighthearted music continues)
Attached to her underside
is her brood of over a thousand eggs.
Her challenge is to keep them safe until they hatch
whilst keeping herself well fed.
So like any good parent,
she's come prepared with a solution.
(lighthearted music continues)
On her claws are live anemones
that she's collected from the reef around her.
The anemones filter food from the surrounding water,
which the crab mother steals for herself.
It's an ingenious way to keep energised
while looking after young.
But it's not without risk.
(apprehensive music)
To capture the food she needs,
she must take her anemones out in the open.
(apprehensive music)
A cuttlefish,
a cunning predator that pounces on the unprepared.
(suspenseful music)
Exposed and alone,
she is a sitting crab.
(suspenseful music)
But she isn't defenceless.
Her anemones have venomous stings
that can deter most predators,
a very effective weapon for a mother in need of protection.
(apprehensive music)
In fact, her anemones are such good tools
that they are highly prized amongst the crab community.
(lighthearted music)
And this mother has a jealous rival.
(apprehensive music)
(lighthearted music)
Empty clawed, her opponent will do anything
to secure her own anemone.
(apprehensive music)
(suspenseful music)
She isn't going to surrender them without a fight.
(suspenseful music)
Overpowered, the mother loses one of her anemones.
The battle leaves her exhausted and vulnerable.
She needs to lie low and buy herself some time.
(gentle music)
Because this supermom has yet another trick.
Slowly and meticulously, she dissects her remaining anemone,
creating a clone.
(gentle music)
Her remarkable problem solving
allows her to keep herself and her young alive
for a few more days,
until eventually she's ready to let them go.
(gentle music)
climbing to the top of her coral home,
she begins to release her tiny offspring into the current,
a few at a time,
until all her crablets are independent.
Thanks to her care and attention,
she has given them an excellent start in life.
(birds chirping)
Raising offspring alone is extremely challenging,
so many parents resort to teamwork.
(lighthearted music)
A female burrowing owl is looking for a partner
amongst the wild lands of Arizona.
And this young male seems eager to please.
(lighthearted music)
To win her over, he must first find a decent burrow.
And that is proving tricky.
Burrowing owls use holes abandoned by other animals.
But the ones he's found are either still in use
or already have well-established families.
(lighthearted music continues)
Her patience is running thin.
(birds chirping)
When finally he's found one,
she flies in for a closer inspection.
(lighthearted music)
(soil rustling)
The hallway clearly requires a little housekeeping.
Though small inside, it's deep enough underground
to keep her chicks cool in the midday heat.
(lighthearted music)
Returning to await her verdict,
he receives a less than enthusiastic yes.
Over the coming weeks, she will lay one egg a day
and then incubate them all until they hatch.
(lighthearted music)
His responsibility now
is to provide her with a constant supply of food,
until eventually their teamwork pays off.
(lighthearted music)
(chick chirping)
(chicks chirping)
At first, the father's food supplies are enough
to keep their chicks growing.
(chicks chirping)
But soon, both parents will have to work
to put enough food on the table.
(owl squawking)
(lighthearted music)
(chick chirping)
(lighthearted music)
(chick chirping)
All this constant activity inevitably attracts attention.
(apprehensive music)
(roadrunner cooing)
A roadrunner.
(roadrunner cooing)
Fast and wily, this opportunist could kill
an entire brood of young chicks.
(apprehensive music)
Their burrow has been chosen
to keep them hidden from predators.
(apprehensive music)
But at the first sign of danger,
the chicks create a deterrent.
(chicks hissing)
Their call mimics the sound of an angry rattlesnake.
(chicks hissing)
But rattlesnakes are one of the roadrunner's favourite prey.
(apprehensive music)
Returning with takeaway,
the father is alerted to the danger.
(apprehensive music)
(suspenseful music)
(owl squawking)
Disaster averted.
(roadrunner cooing)
(owl squawking)
(roadrunner cooing)
(owl chirping) (lighthearted music)
But now, both parents are caught
between keeping a watchful eye on their chicks
and providing enough food for them to grow large enough
to defend themselves.
(lighthearted music)
(chicks squawking)
They work around the clock.
(chicks squawking)
And their chicks' expectations are seemingly never ending.
(chicks chirping)
The parents' lives soon reach a turning point.
(chick squawking)
The growing chicks begin spending more and more time
exploring their surroundings.
(lighthearted music continues)
And there are less demands on the parents
as a few of the chicks become capable
of finding their own snacks.
(chick squawking)
For the parents, that is a welcome relief.
(chick squawking)

Parenthood is even harder
when the environment is working against you.
And for those parents who need reliable fresh water
to raise their young, the conditions are rarely perfect.
(birds squeaking)
The Ruaha River in Tanzania.
For most of the year, it provides a lifeline
to those that live here.
But during the dry season, this refuge almost disappears,
leaving this mother hippo and her calf with a dilemma.
(hippos huffing) (hippos grumbling)
(water splashing)
(water sloshing)
He was born just two months ago,
at a time when water was plentiful.
(hippos grumbling)
(hippo huffing)
But now, there are only a few pools left
where the water is still deep enough
to shield him from the harsh sun.
(hippos grumbling)
The other hippos in the area have had the same idea.
So her newfound nursery has become
a little crappy.
(lighthearted music) (water splashing)
(hippos grumbling)
(water splashing) (hippos grumbling)
(water splashing)
For now though,
hygiene is the least of the mother's worries.
(hippos grumbling) (hippos huffing)
These enormous fountains of fertiliser
require 50 kilos of vegetation every day.
(hippos grumbling) (hippos huffing)
And now, in the dry season,
that is a problem.
(apprehensive music)
Good grazing is nearly one and a half miles
from the safety of the river.
(hippo grumbling)
But it's too hot to make the journey in daytime.
(hippos grumbling)
she must wait until nightfall.
(apprehensive music continues)
In the cool of the night,
the surrounding bush comes alive.
(eerie music)
But with darkness comes the unknown.
(animal growling)
(apprehensive music)
Like it or not, the hippos
must leave the safety of their pool
and head into the night in search of food.
(apprehensive music)
(water splashing)
(apprehensive music)
The mother must not leave her calf alone.
So the pair begin the slow and uncertain walk
to find distant grazing.
(apprehensive music)
(hippo grumbling) (birds squeaking)

(animals squawking) (animals grumbling)
(animal snarling)
(apprehensive music)
There is some safety in numbers close to the water.
But this far into the dry season,
the best food is further away.
(animal squawking)
Their size offers them some protection.
(apprehensive music)
The hippo mother is a formidable bodyguard.
Her mouth is filled with 20 centimetre ivory tusks
that serve only for defence.
(apprehensive music)
But a young hippo is vulnerable.
So the calf must never stray too far from his mother.
(animal bellowing)
(grass rustling)
(animal squawking)
(apprehensive music)
(grass rustling)
(bird squawking)
(grass rustling)
(apprehensive music)
(grass rustling)
(apprehensive music)
There is an unnerving quietness to the bush around her.
(apprehensive music)
But now, they are too far from the water
to seek refuge there.
And their stalkers know this.
(apprehensive music)
(grass rustling)
A nearby male also senses danger, and he joins the mother.
Even in small groups,
hippos can defend themselves against a single lion.
But not against a pride.
(lion snarling)
The mother knows if they all hold their ground,
they might have a chance.
(hippos grumbling)
The less experienced male panics.
(hippo grumbling)
(apprehensive music)
And they lose their advantage.
(hippos grumbling)
(calf grumbling)
(hippos grumbling)
(lions snarling) (hippo groaning)
(sombre music)
The body of a young male hippo
will keep a pride fed for a week.
The mother and her calf
return to the protection of their pool.
They have had a lucky escape.
But the mother hippo's remaining refuge will soon dry out.
And she and her calf will have to travel further and further
into the unknown.
They'll need to do this every night.
All parents need dedication in the face of adversity.
(hippo huffing)
The quest for food
can be a seemingly never ending commitment for many parents.
(birds chirping)
And here in Namibia, one takes that commitment to extremes.
(web rustling)
This female African social spider
laid her eggs just days ago.
And now her brood of 30 spiderlings
are dependent on her for food.
(enchanted music)
So in their early life, she regurgitates a milky liquid
which the spiderlings drink directly from her mouth.
They will grow to 10 times this size in the coming weeks.
To fuel such growth,
she will need to leave her nursery to hunt.
(enchanted music continues)
Luckily, this mother has family she can rely on,
50 fully grown adult sisters who share her nest
and who hunt in perfect unison.
(lighthearted music) (web rustling)
By stopping simultaneously,
they can listen with their feet
to detect the whereabouts of their prey in their vast nest.
(web rustling)
(apprehensive music)
(web rustling)
(enchanted music)
Within weeks, her spiderlings
are ready to start hunting for themselves.
And as they grow, her offspring and all their cousins
become insatiable.
(apprehensive music)
They're born with the ability to hunt together as a pack,
just like their mothers.
(apprehensive music) (web rustling)
Only now, there are over a thousand of them.
(apprehensive music)
(web rustling)
(apprehensive music)
(fly buzzing)
Her role is almost over, which is just as well.
Since laying her eggs,
the mother's condition has been deteriorating,
and her movements have become laboured.
The demands of parenthood are finally taking their toll.
(sombre music)
But she has one more gift for her offspring,
the only thing she has left.
(apprehensive music)
(web rustling)
Her struggling appears to mimic the vibrations
of a distressed prey insect.
(apprehensive music) (web rustling)
And her hungry spiderlings descend en masse
to their mother's dinner table one last time.
(apprehensive music)
Only this time, she is the main course.
(apprehensive music)
(web rustling)
(suspenseful music)
(web rustling)
Hers is the ultimate sacrifice,
born out of a need to ensure the survival
of the next generation.
(apprehensive music continues)
But the spiderlings are not yet finished.
(apprehensive music)
They turn on their surviving relatives,
eating every adult in the colony one by one,
until the next generation
is all that is left.
(birds chirping)
Parental sacrifice on this scale
is rare in the natural world.
Though there comes a time in a parent's journey
when all that effort seems worth it.
(lighthearted music)
A female western lowland gorilla in Gabon.
She will help her young for almost four years
to learn the complexities of living in their jungle home.
(lighthearted music continues)
But as he becomes more independent,
she must let go
and allow him to acquire the rules
of a gorilla's social life.
(gorilla squawking)
His newfound independence
triggers a crucial moment in his mother's journey.
(lighthearted music continues)
It gives her the chance
to think about her next stage of parenthood.
(lighthearted music)
The father of her young one
is reaching the end of his prime.
At 34, he's old for a silverback.
And unbeknownst to him, he is under constant assessment.
Female lowland gorillas will leave their troop
if they think there might be better options.
(lighthearted music)
And that decision all boils down to one thing.
Has he still got it?
(gorilla huffing)
(lighthearted music)
(gorilla grumbling)
Hmm, not bad.
(lighthearted music)
Her offspring will inherit his excellent physique,
giving him a good headstart in life.
(leaves rustling) (ground thudding)
(gorilla squeaking)
(leaves rustling)
Brawn isn't the only thing she considers.
(lighthearted music)
Though males play a little part in raising their offspring,
females nonetheless prefer males with a degree of tolerance.
(gorilla huffing)
And the old silverback has always been good with kids.
(lighthearted music)
(gorilla squeaking)
(leaves rustling) (gorilla grumbling)
(gorilla squeaking)
(leaves rustling)
(gorilla grumbling)
On top of his physique and character,
she's also constantly assessing
what his territory has to offer.
(lighthearted music)
Wherever it comes from,
good and plentiful food is crucial
for any mother trying to raise her young.
(lighthearted music)
And variety helps parents teach their young
about what to eat and where to find it.
In the food department, he scores highly.
(lighthearted music)
He even has a swamp,
which might not sound like much,
but the grasses here provide much needed protein
to a lowland gorilla's diet.
She also is looking for protection when life gets risky.
(apprehensive music)
(elephant roaring)
(chest thudding)
(elephant grumbling)
A forest elephant is not immediate competition
but a threat to young gorillas nonetheless.
(elephant grumbling)
(gorilla huffing)
(gorilla grumbling)
Willingness to stand up to those bigger than him
is certainly attractive in a partner.
(lighthearted music)
If she chose to leave, however,
there would be significant risks.
Any new male with whom she associates
could kill infants that aren't his own.
So she'll have to leave her child behind.
And it would months to establish herself within a new troop.
(gorilla grumbling)
Here, at least she already has a partner,
just a slightly mature one.
(gorilla chattering) (lighthearted music)
For now, it seems he has passed her test.
(gorilla grumbling)
But there's still time to change her mind.
(gorilla grumbling)
(lighthearted music)
Parental strategies have evolved over millennia.
But now, over 80% of the Earth's land mass
is affected by human activity.
And animal parents are having to adapt to this new world.
(melancholy music)
An endangered Iberian Lynx
known as Odrina.
This abandoned barn is the best place left for Odrina
to raise her five kittens.
(cubs purring)
It's an excellent refuge for her growing family,
cool, sheltered,
and full of activities for soft play.
(cub hissing) (lighthearted music)
In fact, this place is so good that Odrina is not alone.
Both her mother and her daughter
have chosen to raise their kittens here.
Three generations raising their young together,
a rare phenomenon and a sign of hope.
But the recovery of lynx here has only been possible
by what has happened outside the barn.
(engine rumbling)
Less than a decade ago, the farmers here
chose to change their practise
to suit the native wild animals.
(lighthearted music)
They stopped hunting
and began creating habitat amongst their crops.
(engine rumbling)
And quicker than anyone had imagined,
the native animals moved back in.
First prey,
then predators.
Soon, the farm became a safe refuge for parents like Odrina
to introduce their kittens
to a world that had been redesigned with them in mind,
one where kittens have room to explore,
play,
and hunt.
(lighthearted music continues)
And they thrived.
We are beginning to understand
that it's possible to use our world for our needs
but also providing for wild animals.
And we are discovering that by doing so,
it's possible to help other species.
(majestic music)
Iberian lynx have begun a remarkable recovery,
but their fate still remains in the balance.
The future is uncertain for all parents across our world.
But what is clear is that for all of us to survive,
we will need to help each other.

The "Parenthood" team relied on experts all over the world.
(team member imitates croaking)
(frog croaking)
And in Loango National Park in Gabon,
primatologist Dr. Martha Robbins and her team
came with 20 years of crucial expertise.
- The idea behind this project is to link research
and conservation of western gorillas.
For this project to succeed,
we need to work together with Gabonese people.
And the Babongo have remarkable tracking abilities,
where they can see things in the forest that we can't see.
(tracker speaking in foreign language)
- [Narrator] The Babongo trackers
take the lead daily into the forest.
And by snapping twigs as they go along,
they leave themselves a trail to follow back.
(lighthearted music)
But it is their carefully crafted relationship
with the gorillas that is key.
(Hermann speaking in foreign language)
- [Narrator] The trackers know they must first help the crew
gain the silverback's trust.
(bird chirping)
- Whoa.
You could feel the power of this massive creature.
Silverbacks are probably the most powerful of all primates.
(lighthearted music)
- [Narrator] And they warn the crew
it isn't going to come easy.
(Hermann speaking in foreign language)
- [Martha] The gorillas really like the swamps
because it's full of tasty gorilla food.
The swamps don't pose challenge for the gorillas.
The swamps pose one of many challenges for us.
- [Peter] You okay?
- Nope.
(lighthearted music)
- [Narrator] The team try as best they can to keep up.
And just as they reach dry land,
the gorilla family have other ideas.
- So we've just crossed the swamp.
We've managed to find the gorillas, which is great.
The gorillas have decided
that they're going to go back across the same swamp
that we've just crossed.
So, yeah, we're gonna follow them across
and do it all again.
- [Narrator] Back on the other side,
they catch a fleeting glimpse.
But the gorillas have yet to accept the crew's presence,
and disappear into the forest.
- So back to searching.
(birds chirping)
- [Narrator] They tracked down the gorillas once again.
But if the crew thought the swamps were hard work,
the mangroves are even trickier.
And once again, the crew are left trailing
in the gorillas wake.
Frustratingly, they decide to abandon the day's search.
(lighthearted music)
A new day, a new lead.
The trackers' familiarity with the gorilla's movements
continues to be essential.
(Hermann speaking in foreign language)
- [Narrator] But the silverback
is still unsure about the cameras
and keeps his family moving.
- I have seen the silverback's bum.
Quite special already, I guess.
- [Narrator] The science team
spot a potential obstacle on the path ahead.
(apprehensive music) (elephant grumbling)
(Hermann speaking in foreign language)
(elephant grumbling)
(Hermann speaking in foreign language)
(apprehensive music)
- There's nothing worse than an angry elephant,
so now we're just making our way around
so that we didn't get in their way or disturb them.
(elephant grumbling)
- [Narrator] Luckily, it isn't a problem for the trackers
to pick up the trail again.
- Fastan just pointed out a track that he just found,
and this is the trace that he sees.
- [Narrator] A moment of calm in the forest
allows the crew to finally set up.
(rain pattering)
But just as they do so, the rains arrive.
A wet camera could spell the end of their filming trip.
(boat rumbling)
So they're forced to retreat once more.
- Ah, it's so wet. (chuckles)
(mystical music)
- [Narrator] Overnight, the rains
have washed away the tracks of the gorillas.
But the trackers pick up another sign.
The freshly stripped twigs indicate gorillas
have recently been feeding here.
(lighthearted music)
And now it seems the silverback
is willing to finally allow the crew access.
- So cool, so cool.
- [Narrator] Over the following weeks,
the science team helps the crew
to understand the gorillas' behaviour.
- A big reward is discovering new things
that we don't know about these animals.
There's something every day that the gorillas do
that can put a smile on your face.
(lighthearted music continues)
- This shoot would've obviously been impossible for us
without the help of all the amazing guides
and trackers we had.
