There's a story that unites each of us with every animal on the planet.
It's the story of the greatest of all adventures,
the journey through life.
Animals have just one goal at the end of this journey,
to leave offspring.And every one begins its life
with an irrepressible instinct to survive and overcome the odds.
The drive and inventiveness of animals is breathtaking.
Every aspect of their behaviour,
whether it's spectacular or beautiful or simply extraordinary
is their way of meeting a particular challenge.
In this series,
we will see animals of all kinds striving to overcome the obstacles
that face them at each stage in their lives.
They will be strong.
They will fight battles.
And will do whatever it takes to win a mate.
Each success leaves each individual one step closer
to leaving offspring -
the next best thing to immortality.
The journey through life begins afresh with every new generation,
as it has for countless millions of years.
It is life's great story.
I'm in South Africa, sitting beside a colony of meerkats, waiting
for this year's youngsters to emerge and start exploring their world.
Here they come. That's the adult.
They must check the coast is clear.
There's another one.
Ah, there's a baby.
Hello, little one.
We can't know what the future's going to hold
For this little creature.
Just as every one of our histories is unique to ourselves,
so this animal too will have its own story.
If one of these little creatures,indeed, if any animal
is to become one of life's winners by leaving behind offspring,
then a long and difficult journey lies ahead.
This is the story of life,
and for these little creatures,it's just beginning.
Good luck to you.
Many animals face their greatest
challenge within days or even hours of entering the world.
This is when they are smallest and most vulnerable.
The remote Orsted Dal Valley in Greenland,
scene of one of the most extraordinary trials that any animal
must face at the beginning of its life.
Newly hatched barnacle geese.
Their parents chose to nest on top of a huge tower of rock.
Such extreme isolation was the only way
to protect their brood from predators on the ground.
But now there is a price to pay.
Up here, the five goslings may be safe and warm,
but they have nothing to eat and they're getting hungry.
Like their parents,they only eat grass, and to find it
the goslings must first get down there, 400 feet below.
But they won't be able to fly for another eight weeks.
So they'll have to jump.
The father is restless.
He decides it's time for the family to leave.
He calls to encourage them.
But they are so tightly bonded to their mother
that they will only follow her.
The parents both survived the descent as youngsters.
They're living proof that their chicks can make it.
The fluffy goslings are certainly light and well-padded.
But luck will play its part.
At the bottom of the cliff, their mother calls for them to join her,
and instinct compels them to follow.
The gosling spreads its body and flaps its tiny wings
to slow its descent and lessen the impact of inevitable crashes.
If the first collision is belly-first,
it should survive the fall.
This chick jumps off the back of the cliff.
It's less of a drop,
but there's far more risk of getting lost in the crevices below.
The third makes another good jump.
But the fourth slips.
Plummeting down headfirst,
too close to the cliff,could bring disaster.
The third gosling is doing better.
Hitting the rock belly-first should prove a life-saver.
But still the tumble goes on.
ADULT BIRDS HONK
There is nothing its mother can do but follow it down.
One last chick.
The perfect launch.
And a controlled drop.
This is as good a descent as it's possible to make.
Its parents are there to meet it.
A little dazed perhaps,but all in one piece.
One gosling, at least,hasn't made it.
And this chick appears to be in a bad way.
At last, it responds to its mother's calls.
The resilience of a barnacle goose chick is extraordinary.
But there are still chicks unaccounted for,
somewhere amongst the rubble.
The parents can't risk searching because they need to lead
their two survivors away quickly,before predators arrive.
A third one has made it.
But it needs to catch up.
Three out of five chicks have made it.
Without such a dramatic start in life,
it's unlikely any of them would have even got this far.
These chicks will face more dangers in the future,
but only two days old，they've already survived
the greatest challenge of their lives.
A young animal significantly improves its chances of surviving
if it can grow fast, and few babies have more growing to do
in their first weeks than a humpback whale.
In just six weeks, this new-born calf must leave these nursery waters
off Hawaii and start on a 3,000-mile migration
to its feeding grounds in the Arctic.
For that, it will need to be strong.
Twirling at the surface
rapidly develops muscle strength and diving ability.
Before then, this one-tonne calf must double its weight by drinking over 3,500 pints
of its mother's fat-rich milk.
But the milk supply is limited.
Until its mother reaches the feeding grounds, she's fasting.
Humpback calves make such demands of their mothers
that females can only raise one every two or three years.
