All language subtitles for Whale With Steve Backshall 04

STEVE BACKSHALL: Whales...
(WHALESONG)

..ocean giants, ancient mariners.

Their songs, majesty and sheer size

fill us with joy and awe.

In their vast shadow,

a human can feel very small.

They were here long before us...

..caring for their young...

..hunting...

..voyaging.

But now we are changing their world.

So now I want to see
through their eyes,

meeting them on their terms

to find how their future
and ours are inseparable.

(RAPID CLICKING)

I've dived with whales and dolphins
right across the globe...

..and have seen just how much
we're changing their world.

(GROANING)

The noise we make in our seas

'is drowning their voices out.'
(VARYING TONAL WHISTLES)

Modern fishing practices
can deplete the food they rely on.

And a changing climate is forcing
them into longer migrations...

..putting their young at risk.

Now I've come to my home seas...

..to find out
what we can do to adapt...

..and help ensure
their future success.

Our wild coastline

is the last true wilderness
in Great Britain.

And to my mind,
for majesty and beauty,

equals anywhere on the planet.

It's also a magnet for whales.

Twenty-eight different types
have been recorded here.

That's around one third
of the species in the world.

(VOCALISING)

Some, like orca...

(VOCALISES)

..Risso's Dolphins...

..and bottlenose dolphins,

live here all year round.

Others, like humpback whales...

..fin whales

and sei whales,

are just passing through.

But the future of all of them
hangs in the balance.

The whale is considered
a great conservation success story.

They survived
the era of commercial whaling

when we slaughtered
more than three million of them.

But the return of the whale
has coincided

with monumental changes
for our planet.

Threats like climate change,
disturbance and pollution

are altering the whale's
world faster than ever before.

Now it's time for us to act.

So I want to meet the people

who are working hard
to find solutions.

And to discover what we can all do

to secure a brighter future
for whales and for us.

Our seas might be home to a
huge range of whales and dolphins...

..but the oceans are vast,

and much of whales' lives
are hidden from view.

Finding out how many there are

and how they're faring
is an enormous challenge.

But there is a global hotspot
for cetacean life...

in Scotland.

So that's where
I'm starting my journey.

I'm joining
a pioneering team of scientists

who have perfected the art
of finding whales

using not just sight but sound.

For the next few days, we're
gonna be at sea in the Silurian,

a state-of-the-art research vessel

which is specialising
in whale acoustics.

It is the perfect platform for
monitoring whales in these waters.

Morning you all!
MAN: Morning, Steve.

Whales make all kinds
of different sounds.

(WHALESONG)

From humpback song...

..to the complex clicks
of sperm whales.

(RAPID CLICKING)

And here on the Silurian,

Scientist Jenny Hampson
is using these sounds

as a way of finding them.

So this is our hydrophone, it acts
like an underwater microphone

allowing us to monitor the acoustic
environment underneath the waves.

We don't know what we're gonna find
on our three-day journey.

but it's not long
before we have our first encounter.

We have company.

A pod of common dolphins.

Utterly spectacular!

They're set apart
by the golden hourglass shape

that runs down their sides,

and we have a decent sized pod here.

They're super, super social.
Very playful.

Uberintelligent.

'Dolphins are also
the masters of communication.'

(VARYING TONAL WHISTLES)

Over 6,000km away, in the Bahamas...

..I experienced
their use of sound first-hand.

Freediving allowed me to enter their
world as silently as possible...

(VARYING TONAL WHISTLES)

(RAPID CLICKING)

..and hear and even feel
their vocalisations.

Scientists here
are decoding their language.

They've found that whistles are used
for long-distance communication...

(VARYING TONAL WHISTLES)

..and as calls, between mothers
and calves when they're separated.

And burst pulses, packets of clicks
spaced tightly together,

tell us about
the dolphin's emotional state...

..from aggressive to amorous.

(RAPID CLICKING)

As our seas become awash
with man-made noise,

dolphins' intricate communications
can be drowned out.

(ENGINE RUMBLING)

So it's more important than ever
that we better understand them.

And here on the Silurian,
in Scottish seas,

I want to take it a step further,
by listening in to the hydrophone

to hear another incredible way
they use sound.

(DOLPHINS VOCALISING)

That's so clear.

Absolutely amazing.

(VARYING TONAL WHISTLES
AND RAPID CLICKING)

It's a kind of range
of clicks and splats,

which is echolocation.

This is biosonar,

which is just a way of building up
a picture of things in your world

without using sight.

Every sound they record
helps Jenny and the team

build a picture of how many whales
and dolphins are in these waters.

Data that can be used
to better protect them.

The study of whales and dolphins

has been aided by technology
invented for military use.

In the 1950s, the American Navy
detected a mysterious sound...

..a metallic-like "boing".

(METALLIC BOING SWELLS)

For decades, no one could work out
where it came from.

And it was only when scientists
started to listen to the ocean,

that they were able
to solve the mystery.

The source was an animal
that's found in British waters,

but is one of the hardest to spot.

The minke whale.

The minke whale
can be really tricky to spot.

They're quick, they don't have
an evident blow or spout,

and so the best way of finding them
is the old-fashioned way,

watching out
for the characteristic shape

of their dorsal fin
as they crest the surface.

Behind us!
Oh, wow, look.

Just there. Very close!

Sleek and streamlined,

minke whales can dive
for up to 20 minutes,

only surfacing for an instant
before heading down again.

(SHUTTER CLICKS)

It's in this fleeting moment,

that Jenny tries to take photographs.

Minke whales have notches and nicks
that they have in their dorsal fins

that it makes it really easy
to recognise individuals.

Currently, we have 260 identifiable
minke whales in our catalogue,

and the more we see them,
the more we learn.

During the last century,

over 130,000 minke whales
were killed in the North Atlantic

by the whaling industry,

the most of all whale species
in this region.

Jenny's visual IDs
are an essential tool

to help us find out
how they're faring now.

(BIRDS SQUAWKING)

As I've seen, Scottish waters
are a hotspot for cetaceans.

But some species found here
are fighting for survival.

(VOCALISES)

My mission to reveal what we can do

to help whales and dolphins
thrive in the modern world

has brought me to British seas.

With bountiful shallows
and deep ocean hunting grounds,

predators flock here.

And the most formidable...

..is the orca, or killer whale.

They're supremely intelligent,

and that means
they could be well equipped

to adapt in the face
of man-made challenges.

They learn bespoke techniques
for hunting different species

in different parts of the world...

..depending
on what food is available.

But sometimes what they hunt
comes as something of a surprise.

While observing orca
in Northern Norway,

I witnessed them
targeting a very unlikely prey.

Wh-What is that?

They're hunting something.

These orca
have turned their attention

to a tiny seabird
called a little auk.

(SQUAWKING)

You can see it jumping
and leaping out of the water

trying to escape them
and then diving down.

It almost looks like
they're playing with their food.

But there's likely
to be more to it than that.

One suggestion is
that it's teaching their calves.

So they're learning skills
that they might use in later life

on bigger more substantial prey.

For now, though, the lesson's over,

and the little auk's fate is sealed.

(BIRDS SQUAWKING)

Orca may appear brutal, even cruel,

but that is a part

of their creative and experimental
way of finding food.

They're always testing
the boundaries, learning

and ultimately adapting.

But this can also lead them
into harm's way.

Something that can be seen in action
on the Scottish Coast,

where every year in early summer,
groups of orca return.

Some are fish-feeding orca
from Iceland,

but once here, they switch...

..supersizing their prey to seals.

Seals are abundant on these shores.

The coves and inlets offer shelter.

And beneath the surface...

..precious kelp forests,
full of fish,

provide plenty of food.

A place to investigate
anything that catches their eye.

Right now,

that's me.

But, unfortunately for the seals,

they're a target for orca.

(GRUNTING AND BARKING)

Swimming close to the shoreline,

the orca search every cove.

Turning sideways
hides their dorsal fins

and allows them
to approach undetected.

Keeping track of an agile seal
is no easy task.

The seal is shared among the pod.

But eating marine mammals
has a hidden cost.

Chemical pollutants
are causing serious problems

for marine life all over the world.

Among the most insidious

are a group known as PCBs,

"forever chemicals",
once used in electrical equipment.

(SHIP HORN BLARES)

Even though they were banned here
in the 1980s...

..they're still finding their way
into our waters.

These chemicals travel
over great distances...

..and concentrate
as they travel up the food chain

into those feeding
on the largest prey,

the apex predators like orca.

(VOCALISES)

They are now one of the
most polluted animals in the world.

Exposure to PCBs can cause
a range of health problems,

including cancer and infertility.

And some scientists think

that within a hundred years
these contaminants could cause

half of the world's
orca populations to collapse.

It's a shocking prediction,

and one that's already
being played out here in Scotland...

..with one particular group,
the West Coast community.

Like lots of the groups found here,

the West Coast community
once had many members.

But in recent years
their numbers have dwindled.

In 2016, the body of one
of the females in the group, Lulu,

was washed ashore.

Her autopsy revealed that she had a
hundred times safe levels of PCBs...

..making her one of the most
contaminated cetaceans ever recorded.

Lulu never had a calf.

No calves have been born
within the West Coast community

for 31 years.

And it's now thought that only
two members of this group survive,

known as John Coe and Aquarius.

Both elderly males.

For orca enthusiast Steve Truluck,

it was this group's predicament
that triggered a lifelong obsession.

I was told the story about them, and
I was just completely blown away,

and I just kinda made it my mission
to make sure that I saw them

before... before they actually go,
before the last two go.

With a distinctive notch
at the base of his dorsal fin,

there's no mistaking John Coe.

And after years
of trying to find him,

in 2019, Steve
finally had his wish granted.

It's John Coe! That's John Coe!
See the massive nick?

This encounter led to Steve
becoming an advocate for orca...

..and a whale spotting guide.

Now he helps others
experience the joy of seeing them

and understand more
about their plight.

Look at that!

We've got John Coe and Aquarius!
We've got the ultimate next to us.

This is unbelievable!
(WHOOPING)

What a steal! (LAUGHS)

Who wouldn't be amazed
at seeing that? It's incredible.

They're just gorgeous. I mean,
they're just amazing animals.

And yeah, just incredible
being in their presence.

As exhilarating
as seeing them was for Steve,

it's an experience tinged
with tragedy.

Highly polluted

and with no females left
to breed with,

there is no way to save this group.

And it's not just orca
affected by chemical pollution.

Other top predators can succumb too.

It's always a sad sight

to see a majestic marine predator
like this washed ashore.

This is a Risso's dolphin.

There's no obvious cause
of what killed the animal,

but in so many places,

when a top-of-the-line predator
like this washes up on shore,

the levels of pollutants
in their body are so high

that they have to be
disposed of like toxic waste.

The imminent demise
of the West Coast community

is surely proof
that we have no time to lose.

Many countries have agreed
to eliminate PCB waste,

but progress is woefully slow.

With an ever-increasing number
of new chemicals

that could have
yet untold consequences,

it's imperative that we prevent them

from entering our oceans
in the first place.

Only then, can we help ensure
orca's survival in our seas.

While Scotland's orca
are under fire,

elsewhere, new revelations
are giving us hope

that some species may find other,
extraordinary ways to succeed.

(VARYING TONAL WHISTLES)

We're learning all the time

just how diverse
our whales and dolphins are.

But sometimes, a discovery is made

that challenges
everything we thought we knew.

For the next part of my journey,

I'm heading to the Isle of Lewis,
in Scotland's Outer Hebrides,

because the dolphins here

have been spotted
doing something remarkable.

Risso's dolphins.

Look at that!

(VARYING TONAL WHISTLES)

Risso's dolphins are unmistakable.

They're stocky with blunt heads...

..and bear the crisscross
of battle scars...

..often caused by rough and tumble
with other Risso's dolphins.

Risso's are generally quite shy,

and that makes them
really difficult to study.

In fact, finding out anything about
their lives has been a real struggle.

Luckily, in the Hebrides,
there's one scientist

who's made it her life's work
to get to know them.

Nicola Hodgins has spent 14 years

studying Risso's dolphins
in these waters.

NICOLA: So this is definitely
one of the Risso's favourite spots.

They've been coming here repeatedly.

Year after year, we get
the same individual dolphins.

It's a really important place
for Risso's.

So you kind of get to know individual
personalities and characters?

Absolutely, yeah, yeah.

And I guess that would mean that
you would be very kind of hardwired

to pick out anything unique
in individual animals.Indeed, yeah.

In 2011, Nicola spotted something
she'd never seen before.

We had some dolphins
come in front of us.

Initially, we thought to ourselves
they looked like Risso's dolphins.

And then there was
a bottlenose dolphin.

And then all of a sudden
there was an individual

who just looked completely different
to any dolphin I've ever seen before

and any species
that we know are in these waters.

Even though it was far out at sea,

Nicola managed to snap a photo
of the mystery dolphin.

We could see this individual was
much larger than a Risso's dolphin.

So, Risso's have got
a very blunt head,

they don't have a discernible beak,

whereas bottlenose dolphins
have quite a discernible beak,

and this individual had a tiny,
tiny, little, kind of snub nose.

And we just knew
we had something really special.

What Nicola had discovered
was a hybrid dolphin,

produced by a bottlenose female
and a Risso's male.

But then it goes
a step weirder, right?

Because if you have
hybrid animals like that,

they're supposed to be sterile,
they're not supposed to be able
to breed.No.

Whereas we now have evidence
of these hybrid dolphins

actually reproducing
and having young of their own.

Would it be too much to say that
this could be evolution in action,

and we could be seeing the birth
of a completely new species?

I don't think it's too much
to say that, and I think a one off,

you can maybe
just put it down to chance,

but this is a repetitive thing

that's happening
with multiple individuals.

The reasons these dolphins
have hybridised aren't yet clear,

but Nicola thinks it could point
to something unsettling.

Is there a possibility
that this could be a response

to larger changes in the environment?

Absolutely.
We're seeing a lot of changes

in distribution
of different species.

So possibly the waters here
are no longer perfect

for either Risso's or bottlenose
for one reason or another,

but they might be perfect
for something

that's kind of in between the two?
Yeah, absolutely.

Evidence suggests that whales
and dolphins all over the world

are venturing
further towards the poles,

and scientists think
this could be down to climate change.

Warming oceans can
radically alter whales' habitats,

pushing them into new waters,

where they mix with new species.

There's still much we need to learn

until we can fully understand
the impact of climate change.

But we do know
that the UK is a place

where the movement of whales
can be studied

because some spectacular species
pass through here

on their mighty migrations.

And when they do,

local enthusiasts
head out to spot them,

making valuable contributions
to science.

Some keep watch over whales
from land.

Others take to the water.

The sea kayak is the perfect tool
for the citizen scientist

so more and more
members of the public,

armed with nothing more
than a camera and a paddle,

are heading out
into our coastal seas

and learning more
about our whales and dolphins

and the information
they are bringing back

is leading
to a much greater understanding

of the world of the whale.

In the far Southwest of Britain,

one local resident
has been doing exactly that.

Rupert Kirkwood
has made it his life's mission

to try to get close to whales

by paddling around
every corner of this coastline.

RUPERT: I absolutely love
calm water,

so I go to whichever beach
around Devon and Cornwall

is the calmest on the day,

and I paddle off out to sea

and may not come back
for 10 or 12 hours.

Rupert always has his camera
close at hand

to capture any marine life he sees.

As I'm paddling along silently,

when there's no wind,
you can hear the creatures.

(WHALE BLOWS, SHUTTER CLICKS)

You can hear the...
(MIMICS WHALE BLOWING)

..the puff of the porpoise.

You can hear the splash of dolphins.

If you're really lucky

you can hear
the blow of a minke whale.

(WHALE BLOWS)

I feel very honoured

to be surrounded
by these amazing creatures.

By far and away
my most exciting encounter

I have had so far
is a very close meeting

off the far tip of Cornwall.

I heard a... (MIMICS BOOMING SPLASH)
..in the distance.

(BOOMING SPLASH)
'So I sat'

actually with my camera
up, ready and running.

Suddenly the fin of a humpback,

the pectoral fin came out,

slapped the water.

This humpback then proceeded
to swim all around my kayak,

engulfing these
huge bait balls of fish.

Because humpback whales
can be identified

by the markings on the underside
of their tail flukes,

scientists were able
to use Rupert's photographs

to catalogue this individual
for the very first time.

It's rather nice that my humpback

is now the most widely seen humpback
around the UK.

It was also one
of the first individual humpbacks

to be identified in English waters.

But since then,
there have been over 100 recorded

around the United Kingdom.

Thanks to people like Rupert,

we're starting to learn just
how important these waters might be

as a stopping off point
for passing migrants like humpbacks.

Adding to the growing evidence

that these seas should have
greater protection for whales.

Humpbacks might appear
to be doing well,

but there's no doubt
that our changing world is putting

all our whales and dolphins
under huge pressure.

And in the final part of my journey,
I want to show how,

even if you can't
venture out to sea...

..any one of us can still do
something to help protect them.

I've seen first-hand

how whales are adapting
to survive in the modern world.

(RAPID CLICKING)

From the ways they communicate...

..and hunt,

to the epic voyages they undertake.

I've also witnessed
how we impact their world.

Our whaling industry nearly
wiped some species out in the past.

And the pollution in our seas

threatens their survival
in the future.

Now they need our help.

Luckily,
many people are taking notice...

..and doing what they can.

And at Chanonry point, in Scotland,
there's a perfect spot

to witness the passion
people have for these animals.

Chanonry Point
is a narrow spit of land

jutting out into the Moray Firth.

At the exact right time of the tide

salmon pour through here
and the predators follow,

making it the best place
in the nation

to see dolphins from the land.

Oh!

These are bottlenose dolphins.

Around 200 are found here
in the Moray Firth...

..a sea inlet that fills with salmon

as they run from the ocean
towards neighbouring rivers.

We have the biggest bottlenose
in the world in our waters.

They can be over 3.5m in length,

even getting close to 4m,
and that is a big animal.

At times they are so close,

it feels like you could reach out
and touch them.

There is something
so, so special about this place,

having a pod of wild predators
hunting mere metres away

from the dog walkers
and people snapping selfies,

but every once in a while, you have
to look back and see the human faces,

see the effect
that it's having on people,

the sense of pure joy,
and I can feel it myself.

Oh, what! Ooh! Ee-hee-hee-hee!

It's a time when their world
and ours truly meets.

Not many places in the world
that happens.

But it's not just the public
that come here,

experts are also drawn
to these waters

in the hope of learning more.

Barbara Cheney specialises
in monitoring bottlenose dolphins

and has tracked entire dynasties
in the Moray Firth.

We're quite a special project here

because it's one
of the longest-running in the world.

They've been studying
the bottlenose dolphins

in the Moray Firth since 1989,

and actually,
we're into our fourth generation.

Barbara uses
ground-breaking technology

to assess the health
of individual dolphins.

(SHUTTER CLICKS)

Her camera's equipped with lasers
which can measure the dolphins...

..and she sends up drones

to get detailed images
of their width,

a great indication
of how healthy they are.

The big goal with science
is data over time.

What are you starting to learn now?

Although they're
still a small population,

there's only just over 200,
actually they're doing quite well

compared to other cetacean
populations around the world.

So we know that
the abundance has been increasing

over the last three decades.

We know that reproduction
has been increasing as well,

so it's actually all
really good news, which is great.

One of the reasons Barbara thinks
the dolphins are doing so well here

is that,
thanks in part to her research,

the Moray Firth has been granted
extra protection for marine life.

That means disturbance
from activities like fishing,

development and boat traffic
are kept to a minimum.

We know that
when we protect areas of our ocean

and create safe havens

it can do wonders for
whale populations around the world.

(SHIP HORN BLARES)

In New Zealand, the port of Auckland

used to be a hotspot for ship strikes
with whales like Bryde's.

But local researchers
and the government worked together

to introduce
lower speed limits for boats,

making sure whales
have time to move out of the way.

And in Mexico, anti-hunting laws
and restrictions on fishing gear

have created an ecotourism industry

that sees grey whales
better protected...

..and now actively seeking out
human contact.

Our individual actions
can add up to make a big difference.

And here in Scotland, the
protected waters of the Moray Firth

seem to offer the resident bottlenose
everything they need.

But even so,
they can still get into trouble.

During high tide,
the bays are filled with water.

But when the tide recedes,
which it does at speed,

there's nothing but dry land.

This expanse of sandbars and mudflats
and salt marshes is Nigg Bay.

It's a wonderland
for birdlife and seals.

And in 2016, it was the setting
for a real-life dolphin drama.

It was here that
a young female bottlenose dolphin,

known as Spurtle, was stranded.

Passersby, Michael Robertson
and Lorraine Culloch,

were the first people to spot her.

LORRAINE:
Aw, she just looked so sad.

I've never seen anything so sad,

and it actually
looked like it was crying.

It was quite emotional.

MICHAEL: I'd probably go as far
as to say it was the saddest face
I'd ever seen.Yeah.

It was unbelievable, even looking
at the photos now, that's awful.
It's quite emotional.

She was suffering from sunburn,

with the skin on her side
beginning to bubble up.

Michael knew
she needed professional help,

so called the British Divers
Marine Life Rescue Service,

or BDMLR -

experts in helping
stranded whales and dolphins.

When the BDMLR comes,
they included us in the rescue.

We'd monitored her breathing.

But basically 14 hours
we had to wait

until the tide came back in,
so they could refloat her.

We slept in the van
in a layby all night.

The next morning, when
the tide eventually came back in,

Spurtle was refloated.

It seemed unlikely she'd
still have enough strength to swim.

But to everyone's relief,

she headed slowly out
into open water.

There's no doubt that
Michael and Lorraine's quick thinking

and the rescue team's dedicated care

saved her life,

but no one knew
whether she'd survive the ordeal.

In the coming months and years,

her sunburn wound,
which at first looked deadly,

healed into a distinctive scar
like a paint splash

And the best possible sign
that she's returned to full health

is that she's recently had
a calf of her own.

Here at Chanonry Point...

..all eyes are on the water

hoping to get a glimpse of her.

Spurtle! It's Spurtle!

Oh, my gosh. I don't believe it.

The... W-Wow!

Well, so we've just had a glimpse

of one of the most special
individual dolphins in our waters.

A true tale of survival.

An animal that
has gone through stress and pain

that it's
almost impossible to imagine

and is back here in front of us,

alive and well.

Evidence that these animals

will battle
against impossible odds to survive,

and now she's back
with a calf of her own.

It just doesn't
get any better than this.

Whales and dolphins have
the unparalleled ability

to fill us with joy.

And my journey with them is something

that will stay with me
for a lifetime.

It's also been a wake-up call.

I've seen how our actions
are threatening their world.

(RAPID CLICKING)

I've also seen how people are doing
their very best to help them.

Even the smallest action,

be it making a phone call

or reporting a sighting...

..can lead to meaningful change.

Whales are adapting
as well as they can.

Now we need to adapt, and fast,

if we're to give them, and us,
a brighter future.

They've been around
for 50 million years,

and they could be around
for 50 million more,

but only if we ensure
the health of their seas.

To capture the astonishing diversity
of whales that are in British waters,

we took to land,

sea... and air.

(DRONE WHIRRING)

But when it came to tracking Orca...

..we knew
we'd have our work cut out.

These incredible predators
roam up to 160km a day

in the search for food.

So for our wildlife cameraman,
Louis Labrom,

pinpointing their location
was to be no easy task.

The challenge
we've set ourselves is quite tricky.

Where do we go?
Where's the best spot?

Where are they gonna come to?
It's a difficult challenge.

Luckily,
we weren't doing it on our own.

We were joining a network
of around 200 volunteers,

including local people
and those taking part

in a citizen science event
called Orca Watch.

They record any orca they see,

giving us some idea
of how they're faring here.

These are his photos from 2km away.

Orca enthusiast Steve Truluck
was also on hand.

The whole thing is
you have to be in it

for the long game,
and you have to wait.

With the whole of the Caithness coast
and the Northern Isles to cover,

the volunteers face a daunting task.

Luckily, the landscape
gives them a helping hand.

There are some parts
of the coastline here

that almost appear
to be natural lookout posts.

Any orca coming,
you can see it from miles away.

You've got a cracking view here
of everywhere.

You can actually see
right down to the cliff.Yeah.

Sure enough, it's not long
before we hear of a sighting.

Oh, really?
WOMAN: Yeah.Ooh.

A fisherman off of Durness
has seen a pod of orcas.

One massive male. Oh!

We drop everything and head to where
we expect to intercept them...

..but the orca outsmart us.

There's been a post put up
that the orcas were seen
at a place called Sandwood Bay,

which is the total
opposite direction of where we are.

So, yeah, unfortunately, no luck
today. They've gone the other way.

Over the coming days,

Louis tries again...

..and again,

in the hopes
of getting a glimpse of them.

(VOCALISING)

But the orca have been covering
vast areas of water every day

and always staying
one step ahead of our cameras.

Louis' not giving up,
but I have to tear myself away

and head 200km south,

to capture
another wildlife spectacle...

..the Moray Firth's
bottlenose dolphins...

Yes. Yeah, yeah, yeah!

..feasting on salmon.

Oh, yes. Metres from shore, Tom.
Metres from shore.

You've always got a good chance
of seeing dolphins at Chanonry.

If only the orca further north
were this predictable.

That's great.

But Louis' finally
got some good news.

WOMAN: (ON PHONE) They're heading
down towards Balchrick, just now.

A whale watcher has spotted
some orca out at sea,

and Louis takes a leap of faith
and hops onboard a passenger ferry,

in the hope
he'll see them as they pass.

We're getting on the ferry! (LAUGHS)

I'm not getting my hopes up,
but also it would be...

incredible, incredible to see them.

And finally, out of nowhere,

an unmistakable flash
of black and white.

Yeah, there they are.
Yeah. Got 'em. Got 'em.

Alright, yes!

This is the much-loved pod of orca
known as the 27s.

And great news...

There's a little one.
'..they have a calf.'

(CHEERING AND WHOOPING)

Now their pod
is eight members strong.

Wah-hoo! Wah!

These guys have put in
so much hard work, and...

they're all so passionate about it,

and some of them
have been out for weeks.

And now they get to see it, and
I'm here seeing it with them, so...

I'm not crying,
it's just the wind in my eyes!

(SHUTTERS CLICKING)

With two incredible wildlife
encounters filmed at the same time,

I can't wait
to catch up with the crew,

once they're back on shore.

How are we?

Very, very happy.
Mm. Good.

What an amazing job!

Well, orca on the British Isles,
it was really wonderful to see.

It's our last day filming,
so last-day luck.

Revealing the challenges orca face
was only possible

because of the passionate people
doing their best

to help whales in any way they can.

And it's that passion
we'll need to harness,

across nations and oceans,

if we're to ensure
the future of whales in our seas.
