Episode 4 Planet Earth Live

Right now it's make or break time for animals across the world. From

here in North America, around the globe, from Sri Lanka to South

Africa, we're following the daily daum yaz of these animals, as they

unfold every step of the way -- Hello I'm live in the Kenyan Masai

Mara. It's lunch time for Julia in the USA. It's gone 10pm here in

Africa. In the Northern Hemisphere it's spring. In the Tropics, the

rainy season has changed everything for our lions and elephants. There

is so much going on. May is a month unlike any other in

the natural world. The challenges it brings to the lives of baby

animals around the planet are the toughest they will ever face.

We've got teams stationed around the globe, following the action

24/7 and reporting on events as they unfold. Tonight, we bring you

the latest on the attempt to save elephant Sylvia's life, after she

was shot by poachers. Julia discovers why year old bear

cubs have been attacked by their mothers at this time of year. And

we travel to South Africa, to find out if Swift and her family spent

the night in enemy territory or braved the trorz of the road.

-- terrors of the road. None of us know what their fate will be.

Whatever it is, we will bring you the latest twists and turns in

their stories, as they happen, both hor and on the web.

-- here and on the web. Hello and welcome a very windy

Minnesota. We're surrounded by thousands of lakes, millions of

rustling trees and 25,000 black bears. Of course, spring came early

here. And then suddenly it kicked into reverse with heavy snowfall,

into reverse with heavy snowfall, really putting our young bear

families to the test It's not just the tiny black bears having a tough

time here, throughout May. Our juveniles, the yearlings are facing

tough times as they get ready for family break up, when they're

forced from the family group to fend for themselves for the first

time. We'll of course, have the latest on Sam, Sophie and Sybil,

the young bear cubs we've been following closely. We've got our

concern abouts little Sybil. We've got the very latest from experts on

those incredible scenes in California, when humpbacks

intervened on a killer whale attack on grey whales.

Join me for the bear and whale news later on. Now let's go 8,000 miles

back to Richard, where he's waiting under the stars.

Thank you Julia. I am under the stars. There's no rain, in the

rainy season. Welcome back to Kenya and the heart of the Savannah where

we're following the lion, specifically two particular ones

crews have been following, baby cup Moja and his mother. They are

outcasts, living outside their pride. They are struggling. These

are the latest pictures we have of them, taken just yesterday. Moja

was holed up in his den. Our crews couldn't get near him. His mum was

out hunting for him. This is the hardest time to be a lion in the

Masai Mara. This is why. It's the rainy season. The graest

wildebeest migration is a month or more away. The plains are empty.

With hardly any food around, Moja is at risk of starvation. Oh,

that's a harsh picture. But he does have something in his favour. An

incredible mum. She is an exceptional hunter. If anyone can

get Moja through these lean times, something to hunt. Right now, at

this time of year, prey is scarce in the Mara. That means lions are

taking on some dangerous prey. Moja's mum knows every nook and

cranny of her territory. There are many secret hide-outs where she can

keep Moja safe while she scans the plains. Male warthogs are strong,

fast and armed with deadly tusks. She spots a huge one. It's a gamble

she's got to take. She leaves Moja safe in his den. The hunt is on. An

adult warthog can run as fast as she can, but she has better

acceleration. She needs to close the gap. The bushes provide perfect

Apology for the loss of subtitles for 46 seconds

thoughts are with Moja. She needs high yeen yaz are quickly on the

scene. The boar is as big as she is. She needs all her strength to drag

ground surrounded by water, the That hunt was filmed by wildlife

camera operator Sophie Darlington who's been filming lions for 20

years, out in the field all day, every day for months, sometimes

years on end. I went out to meet Sophie just after Moja's mum made

that kill to see what she made of our lioness star.

When I got there, Moja and his mum were relaxed and happy after a very

here. You come on that side. Mind your head. I'm minding it. Sorry.

Keep low. That is quite lovely. It's clear that Sophie is

developing a close bond with Moja's mum. She is the most stunning and

astonishing lion, because of her strength, the fact she's surviving

against althe odds and she has got a cub. She shouldn't do that

because she's tough and she's surviving against the odds and, I

don't know, maybe a part of mef as a mummy self-to a little boy and --

a part of me, as a mum myself to a little boy and I feel empathy.

Now, I have an announcement to make, there has been a development, quite

a significant one. You may have noticed during that film, I refer

to Moja's mum as Moja's ma'am and not as Tamu, when only on the other

show we said we were pretty sure we had identified her as Tamu, a

linion first filmed bit BBC six years ago. Since then we've heard

from other experts who disagree with our experts, because they say

and people on Facebook and Twitter as well, that they're pretty sure

she's not that lion. This is the thing, these are wild lions. They

don't generally carry ID. So what it means is there is some mystery

surrounding the identity of Moja's mum. I know, I kind of quite like

that. Whoever she is, wherever she's come, from the one thing we

know for certain, she's learned some amazing and unusual skills to

be able to look after her son in these testing times. Sophie, she

has, hasn't she? Yes. You've spent many hours in the field with her,

whoever she is. Why do you think she's such an exceptional lion?

she's such an exceptional lion? She's unusual because she's on her

own. She has no support or back up, no pride. She's out there hunting

and guarding Moja. She's smart. She's using a tree to look out for

predators and prey. She's hunting. She's so strong. She's hunting

warthog, taking down stuff that could be lethal to her, really

dangerous. She's really brave. wort hog was nearly as big as her.

Using trees is unusual for lions. They do do it. She's canny. She's

also hunting in daylight. Camerawoman's dream! Good for you,

but dangerous for the lion. It's fantastic. She's doing it because

she's avoiding other lions, she's smart. In many ways she's proving

herself to be quite a unique thing. I like the fact that the mystery is

till. There the thing is, what does this mean for Moja? We do know that,

well, whatever it means above all else, with an exceptional mother

like his to look after him, to protect and feed him, he stands a

better chance of making it through these testing times. Jewel ya, I

don't know about you, I think that's actually added to this

mystery back to Moja's mum. Whatever Moja's mum is called, she

is indeed a marvellous mum. Today I can say happy Mother's Day to her,

because it's Mother's Day in America. Welcome back to

magnificent Minnesota. The forecast was for a nice, spring, calm day.

You'll notice by our microphone and if you look out there onto the lake,

it's windier than we anticipated. Our cameraman has been out there

for hours. Thank goodness he's wearing a lifejacket. We're

surrounded by wonderful trees, marvellous wildlife and of course,

thousands of black bears. Let's meet some of those families, one of

those families. This is Juliet, our experienced

black bear muma. She's nine years old and this is her third litter.

Her dark faced male cub Sam is a tinker, who loves playing around

with his sister Sophie. The two of them like a bit of rough and tumble

them like a bit of rough and tumble and enjoy one another's company.

Sybil is the smallest of the three cubs. She's turning into a bit of a

loner. Sybil is now really beginning to

look like the runt of the litter. While her brother and sister Sam

and Sophie are building up strength, constantly toying with one another

and play fighting. Sybil is being left out, possibly suffering. She

isn't bulking up enough. She's missing out on important social

skills. Dr Lynn Rogers, our bear specialist s, concerned about her

because she is looking skinny. The play fighting becomes very serious

when it gets down to feeding wh. It gets down to feeding, it's all

about nipple order. Bears have three sets of nipples.

With those producing the richest milk at the top of the chest. The

cubs fight fiercely over which nipple they suckle from. In this

case, Sybil is being forced from the top nipples to those further

down. Sam especially won't allow Sybil to suckle on his favourite

nipple, guarding it ferociously, as if guarding a territory.

Sybil is left with the less rich milk from lower down Juliet's chest,

meaning her development is stunted compared to her brother and sister.

The cub litter survival rate for a litter of three is quite good,

about 82%. When you unpack that it means 2.45 of the cubs of a litter

of three will survive. So obviously, we're rooting for Sybil. We want

her to be at the right end of that statistic. It's so vital that our

bears eat properly, because they won't make it through the next

hibernation if they don't reach a certain rate. A malnourished black

bear doesn't reproduce successfully either. Earlier in the series, we

introduced you to another black bear, that was Jewel. She's a first

time mum. These are her slivering cubs Herbie and Fern who got caught

in the snow because Jewel didn't know what to do, because of her

experience, she left them out in minus ten degrees far too long. But

very luckily, they did survive because Jewel managed to turn it

around. She eventually gave them the warmth that they need. Let's

lock at that family from yesterday. Let's get the latest pictures from

them. They're looking healthy, bouncy, they're climbing trees. Mum

is occasionally making the odd mistake, look a little whack there

to Herbie. You can hear the contented humming sound as her cubs

suckle and of course, just two cubs so it mean that's they both get the

top nipples. So that's very good news for them. So, we're live near

Minnesota. We've been live in Kenya. Now we have the latest news on our

meerkat family from theical hara in South Africa. These are the very

latest pictures. ( this is Swift, a five week old baby meerkat. She's

part of a large family known as the Whiskers. Last time she hay close

shave crossing a busy road to get to a richer supply of food. What

are you doing? It was a case of out of the frying pan and into the fire.

Cameraman Toby is following their lives out in this dry corner of the

Kalahari desert. May can be a tough time of year for meerkats, as food

is thin on the ground. This year is worse than usual. The rains have

failed and food is even harder to find. That's why the leader of the

Whiskers family has led them to a rival group's patch who go by the

name of kung fu. If this family find the group

stealing from their larder, there will be hell to pay. Swift could

easily become a casualty. Temperatures today are soaring into

the high 30s. Despite the heat, Swift is keen to find her own lunch.

It's a giant mill peed and it has a toxic skin. So Swift has to master

the art of dragging it across the sand to remove the foul taste. The

rest of the family are nervous. They know how dangerous being in

enemy territory is. So everyone's on red alertment Suddenly, there's

an alarmment -- alarm. Swift is too involved in her mill peed to notice.

The family rapidly regroup. At last Swift realises something's up and

runs for her life. In everyone comes. Everyone's up. All these

eyes, all these eyes are keeping an eye out, what is it? They're

nervous as the adults. Guys, concentrate. But it's a false alarm.

It's not the enemy or a bird of prey, it's just a harmless vulture.

Oh, falling asleep, little sister. All this excitement has been too

much for tiny Swift. They're sort of relaxing in the shade of this

tree. After an alarm call, everyone gets quite frisky and playful, look

at that. It's sort of a release of long. They've got to keep moving.

This desert offers such meagre pickings. Swift's got to get used

to these all-day foraging trips. Everyone keeps moving deeper into

enemy territory. By dusk they're far from home. It's too late to

turn back now. So they've quickly got to find somewhere safe to spend

the night. But the nearest burrow is anything but safe. Kung fu,

another meerkat group. This is their burrow deep in their

territory. Now Whiskers have been caught out by the time and are

having to spend the night here. They won't be approaching the

burrow as they do to one of their own. There they're a lot more

nervous, a lot more sniffing, more observant. There's a meerkat, part

-- if I were a meerkat, part of the Whiskers group, I would not sleep

here tonight. Swift's brave cousin Ernesto is one of the first to

check out the hole for danger. It seems clear. They take a chance.

But would they bump into the enemy deep under ground? The following

morning, the meerkats are slow to rise. Spending the night in their

arch enemy's bed was a dangerous decision, but was it the right one?

First meerkat's up. About half the group are up. One pup. Thankfully

everyone's here. The enemy group must have used one of their other

burrows. With Swift an the other three pups accounted for, everyone

is up soaking in the sun's first rays. But half an hour later, a

little hunched figure emerges. Ernesto Swift's cousin is in

trouble. It looks as if he's been bitten by a snake. The venom is

already starting to take hold. can see the mark on hills head here,

his right eye. It's very nearly closed and that general lass tued,

drooping, compare his posture to the other meerkats. They're agile,

aware, light. This is a sick, sick animal. Snakes are a constant

danger for Swift and her family. This desert is home to some of the

most venomous in the world, including cape cobras. The meerkats

response when they meet one is to mob it en masse. They have

astonishing reflexes and somehow avoid every strike. If they come

face to face with one in the depths of the burrow, the skrout come is

very different. -- the outcome is very different. Imagine it last

night, cobra in the dark, this one takes the hit. Poor little Ernesto,

somehow he's managed to drag himself out of the enemy burrow to

be with the family. He's put his life on the line for

Swift and the rest of the family. Will he pay the ultimate price for

stuff. Toby and his team will bring you the next instalment as soon as

they can. Meantime, I guess it's fingers crossed for Ernesto. Turns

out me might -- he might make it. I've been talking to experts, and

they say there's enough venom in a cobra bite to kill me and you, but

meerkats, even though they only weigh less than a kilo, they have a

bit of tolerance. So there say chance that Ernesto might be tough

enough to pull through something that would fell you or I. Fingers

crossed. Welcome back to the Masai Mara in Kenya. This is the rainy

season, but it's not raining. It means things might get busier, if

only with the insects. We have our thermal camera here. There it is.

First time we've seen the cam ra. To be honest, it doesn't look much,

after all the fuss we've made. on there at the moment? Some trees

and that will be a hipo. That glowing lump between the trees is a

hipo. They come out of the water at night to browse and forage for food

and graze. They can travel about five kilometres in a single night

looking for food. That's probably more hippos in the background I

suspect. More shots from the thermal camera as the evening

progresses. We're not here just to look at hippos in the dark and

follow the story of our lions either. A couple of hundred mile

north, we have camera cruise in Samburu, where the rainy season

means different news for the elephants, heralding in new life.

Samburu is in the middle of a baby boom. This has already been a

bumper year with almost 50 new arrivals.

I've been flying north to follow their progress. As commutes go,

this isn't bad. Elephant babies are utterly dependent on mum and their

family to protect them. If they get all the love and care they need,

they're free to start exploring their world. But elephants wander

far and wide in search of food and poaching outside of the reserve is

an ever present threat. Many families have been hit hard by

illegal hunting. Without their elders to guide them, young mums

are struggling to get to grips with motherhood and some older elephants

like Sylvia, are carrying life threatening bullet wounds. On

Thursday, we saw how the wound in Sylvia's jaw was infected and was

swelling day by day. Now the thing is, it's not just Sylvia's life

we're worried about. She gave birth to a calf only a few days ago,

Little Pink Foot. Obviously, pink foot is in danger, though she's

entirely unaware of the big cloud hanging over her life.

Little Pink Foot is just nine days old. Sylvia is an experienced and

atentive mother despite the bullet wound, she's making sure her calf

gets everything she needs. Little Pink Foot has a big sister to lock

after her too. They are very close, even though she has no milk, Little

Pink Foot suckles from her for comfort and reassurance. Sylvia's

condition is becoming critical. If she dies, there would be no-one to

feed Little Pink Foot and she would almost certainly starve to death.

Watching over the herds are David and his team from save the

elephants. They've been monitoring Sylvia. They know they need to take

action. Treating such a huge wild animal is fraught with danger, for

the elephant and the team. But the wound is so serious, David believes

it's a risk they must take. First, anaesthetic to have an effect.

Things are looking good. Little Pink Foot is with her sister, out

of harm's way. Sylvia is easily accessible and the other herd

members are a safe distance away. Sylvia's becoming drouzy. Sensing

danger, she calls to her family. Little Pink Foot rushes back. Now

she's underneath her mother, all three tons of her. This should be

the safeest place in the world for her, but Sylvia's about to collapse.

When she does, she could crush her calf. David has to do something.

But Little Pink Foot will not leave her mother's side. Now as we saw,

and perhaps more importantly, heard there, it was Sylvia's cry that

changed everything and that's the point at which her calf's life was

put in danger. Elephants are capable of really complicated

communication. Experts have identified about 70 specific sounds

already and they reckon that's only scratching the surface. Here's the

thing, David has sedated more than 100 elephants so far. He reckons

they always make the same noise at about the same time when they

realise something is going wrong. Let's hear it again.

That's the noise Sylvia made. David reckon that's noise means danger,

get out of here. So it's not surprising when baby pink foot

heard that noise, rushed in to be near mum. The thing is, that's when

it got tricky because Sylvia had been sedated. She couldn't really

move and she was probably only moments away from falling down

unconscious, which would have been disastrous. There was no way her

daf was going to leave. David faced an -- her calf was going to leave.

David faced an agonising choice. If David moved in himself, he risked

Sylvia falling on him and crushing him. He -- if he did nothing, baby

to get the calf out of the way. She weighs almost 16 stone, 100 kilo

grams. Forcing her to leave her mum is not easy.

They get her out of the way just in Foot panics.

Her family hear the calf's calls of distress and close in.

Her sister looks like she might charge. The team have to get Little

Pink Foot back to the herd as quickly as possible.

A baby elephant's eye sight is poor. They'll instinctively follow large

moving objects, perhaps thinking they're members of the herd. The

team use their vehicles to lead sister, the team get to work. The

abscess is huge. It needs to be service gives Sylvia antibiotics to

help her fight the infection. She is just one of hundreds of

elephants that are shot every year. Many die slowly and painfully.

Sylvia is lucky that the reserve is part of her territory. It's a safe

haven, where help is at hand. When he's finished treating her, the vet

family, but in the wrong direction. David uses the car to shepherd

united. Little Pink Foot can relax in the safety of her herd.

When we keep talking about elephants feeling emotions, we're

not just being soft. Scientists say they can prove they feel them. You

saw them in that film, joy, anger, compassion and love. Scientists

reckon their attachment to their families rival their own. It was a

procher's bullet that caused all that pain, upset and grief. We are

packing a lot into the show, as always. There is so much more

coming up from our crews around the world right now.

Still to come in the show, how with Moja react to a new run-in with the

high evena clan and with Tocque Macaque baby Gremlin get away with

eating another group's figs. Welcome back to the windy wood.

Sorry if I'm shouting. It's difficult to hear out here. It's

not just little black bear cubs out here, there are yearlings out there

as well. They are one-year-old. They're the older cubs. Let's look

at our big black bear family tree, right at top we have Shadow. She's

25 years old and she's had at least nine or ten litters. Juliet and

June are her daughters. Juliet we're following the story of Sam,

Sophie and little Sybil. I want to concentrate on June and her two

yearlings, Aster and Aspen. There yearlings, Aster, a young female

and her brother Aspen. They're just over a year old and

enjoying their second spring with mum.

It's an adventurous existence. Days involve playing with the family,

foraging for food and climbing trees. Mum's teaching them all the

skills they need, ready for life on their mother are drawing to a close.

Sleeping soundly and suckling will soon be a thing of the past. It's

time for family break up. Mother June is coming into season

and the yearlings will soon be seen as competitors for food. This break

up always begins in May and is traumatic for the youngsters. It's

difficult to believe that within a moment, thiser is reen family scene

will be over forever. -- this sern -- serene family scene

will be over forever. That will be the last time we will

see them as a family unit. Because after we finished filming, this

happened. Family break up, after doing

everything for her cubs over the past 12 months, it's time for June

to reclaim some of her territory and to mate again. The cubs, in

this case Aspen, right there, are rejected from the family group and

this is known, this is what we've been talking about, family break up.

It can be aggressive, as you saw there and it is very traumatic.

That's the last we'll see of Aspen. Aspen say male wild black bear. He

doesn't have a collar. He could roam for hundreds of miles now. So

Aspen's gone. What does that mean for Aster? This is June and Aster

two days ago. If you read a bit of body language, June's trying to

hide down an old den there, so she's doing her best to hide from

Aster, but no. Here comes Aster. It doesn't work. She's keen to hang

out with her mum for as long as possible. I don't blame her. This

is incredible footage. We've had cameramen filming in the Northwoods

of Minnesota for five years. They've never captured swimming

before. Black bears swimming, but still mama cannot shake Aster. The

only thing she can shake is herself. Really, really incredible. So these

two were, are, we think still together. I was very keen to find

out if that's the case. Yesterday morning, I went deep into the woods

Apology for the loss of subtitles for 46 seconds

bears experience. Yes. These guys I don't have anything. That's a

good way to judge the size of a Black Country bear. There you go

bear. You can have it. What are you doing? I was feeling how swollen

her vulva is. It's a measure of oestrus. To see whether she's in

season? Yes, she's on her way. an indication that for these two

it's any moment now. Approaching the break up. Which I find hard to

believe, when you lock at this little one. Yeah. She still seems

so juvenile and not ready yet. think, yeah. But she's got her

adult teeth. She can tear into logs. She knows where the big refuge

trees are to run to. She'll do OK. See what a nice bear she is. Yeah,

she's lovely isn't she. She has such a nice temperament. Yeah,

she's going to be a good research bear. Hello! Right now she's a

little ram bunk Saddam Hussein. -- rambunkshus. That will all

disappear. In a week if we try to come out here and home in on her

radio signal, we'll be luck tkwroi see her. She'll hear the voice --

she'll hear the voice and think, when I was with my mother I could

trust that. But not now. Maybe tonight or tomorrow, it will be her

first night alone in the woods. That's right, yeah. If we see play,

it could be the last of the year- and-a-half of play that they've had

together. She'll never play with her mother again.

So after family break up, essentially, the yearlings are on

their own. They forage for themselves, fending for themselves.

They tend to sleep up in the trees because they're so frightened by

every sound they hear rustling around them in the wilderness. We

have got a collar on Aster. Hopefully, we'll be able to keep

track of her movements, when it happens for her. It could be

happening right now, at this very moment.

Welcome back to Kenya in the suddenly dry rainy season. We've

been following up north in Samburu newborn elephants. Crews up there

keeping track of an elephant baby boom. We asked you earlier this

week to help us name a calf, a newborn calf. Here she is. The name

chosen is Maya, after the African- American writer. The baby is only

nine days old. Inskpeerbsed mothers can mean a calf doesn't get the

protection they need -- inexperienced. She's OK now. We'll

update you later in the week. It is dry, so it can be busy out there.

There is a buffalo standing just over there. On the thermal camera,

we saw a hyena. We can look at that. It's not necessarily just looking

to pick up something that somebody else has killed. They are very

effective predators in their own right. The truth of the matter is

they do scavenge and that's relevant to this next thing. Out

there as well gs right now, we have Moja and his mum. We've been

following them since we arrived. Earlier, we saw Moja have a good

field. The thing is, starvation might be staved off for now, and

that was a big enough warthog to feed them for several days. But his

mum can't protect that from their had moved in and claimed their kill.

Not far behind, the vultures. It won't be long before adult males

get wind of the meal. Moja's mum can't take the risk that they'll

discover her son. Moja will certainly be killed. In broad

daylight, she leaves her safe haven. With so many eyes around they need

to find cover and fast. So Moja and his mum are out there

on the move now, skull beinging around in no-man's land. She still

needs to find food as well. It's hard. Sophie will be following them

tomorrow. We will bring you an update when we can. Now getting

hold of food can be dangerous if it brings you into contact with rival

gangs and enemies. What we're going to talk about now, this film has

been sent in late last night from the Sri Lankan team. They've been

following Gremlin baby Tocque Macaque, a lot of fans I know,

together with family. They've had some surprisingly similar troubles

there. Gremlin is a ten week old baby

macaque. She's part of a family growing among the ruins of an

ancient ruins in Sri Lanka. Unfortunately this family has a

strict pecking order. Hectare, the leader, is at the top and poor

Gremlin is right at the bottom. It's something she's constantly

reminded of. Wildlife cameraman Gavin is watching every milestone

in her young life. Gremlin has a curious nature and is

keen to learn. There's certainly a lot to get her head around. Last

time, she managed to say her first words, showing respect for hectare

and avoiding a beating. Her next lesson is learning what's good to

eat and where to get it. It's a pretty varied diet for Gremlin in

these forests. Ranging from birds eggs and insects to fruit, flowers

enough territory and you have to keep it defended against any

competition. Gremlin doesn't know her territory that well yet and

needs to find the boundaries, know every nook and cranny and where to

find food throughout the yearment - - year. And when it comes to food,

this large fig tree is like a supermarket. It's just coming into

fruit now. Figs are a favourite of the monkeys, highly prized and full

of nutrition. Gremlin's family, the temple troop, decide to check it

out. Learning how to tell if a fig is ripe enough to eat will be an

important lesson for Gremlin. But there's a catch. The tree sits

right on the border with some very nasty neighbours. It's the Slumdog

troop, an aggressive, large troop, based in the town. They're led by

Bad Eye. He lost the use of an eye in a previous battle with Hector.

There's old scores to settle between them.

Bad Eye and his slum dogs know the fig tree is almost ripe too. They

will do anything to keep it from Hector and the temple troop.

Gremlin and the rest of the troop are happily exploring the fig tree,

testing the fruit for ripeness. Their constant calling gives

instant updates on the fruit on each branch. It's obviously not

quite ripe enough yet. Their calls have attracted the attention of the

slum dogs. As for as they're concerned, this is their fig tree

and they're prepared to fight for it. Gremlin is at serious risk. If

there's a full-scale fight, any baby captured would be killed. The

advancing slum dogs are spotted by a sentri and the alarm goes up. --

sentry. Gremlin's mum needs to get her out of the way sharpish. As the

two troops face each other, they weigh each other up, body for body,

pound for pound. They're equally matched. The temple troop

youngsters get out of tree and out of the way as fast as possible.

Gremlin's grabbed by her mm and whisked out of harm's way. -- mum.

Hector is more than prepared to fight for his propertyment But the

old king knows the gains must outweigh the risks. Hector's very

wise. He knows this fruiting fig isn't ripe yet. It's not worth

fighting and possibly getting injured over that. But over the

next few days, when the tree comes into full fruit, I think this

battle's going to kick off. Gremlin was lucky this time. She

was within reach of her mother when the Slumdogs turned up. But next

time, this adventurous, but naive little monkey, might not be so

lucky. Very fortunate escape for Gremlin and her family there. If

you can't get enough of Gremlin, and I know you're in love with this

funny little bog-eyed monkey, go to our website and Facebook page,

because the crew in Sri Lanka are putting up behind-the-scenes

footage and also putting up other photographs of Gremlin.

Now we've been following the migration, the essential seasonal

migration of the grey whale and their calves on Planet Earth Live.

They've been migrating along the coast of California towards their

feeding grounds in the Arctic. But it is a perilous journey. Lying in

wait are killer whales intent on hunting down the grey whales, the

mothers and calves and separating them. We filmed an extraordinary

attack on Thursday. We show today to you on Thursday. Take a look

separate a grey whale calf from its mother and were repeatedly pushing

it under the water in an effort to drown it. To even witness an attack

is surprising. But what happened next is truly remarkable and to the

best of our knowledge has never been filmed before. As the orca

continued their attack, the crew noticed two humpback whales, who

seemed to be intervening in an effort to protect the grey whale

and her baby. They appear to be placing their own bodies between

the wounded grey whale calf and the killer whales. Sadly, despite their

best efforts, they couldn't save the calf.

But the humpback whales remained in the area, following the orcas in an

effort to prevent the killer whales from feeding. Six hours later, the

humpbacks were still there, but the killers shared the spoils with the

albatrosses. While the grey whale mother continued her journey north,

alone. Very powerful, what amazed the

eyewitnesses of that attack and amazed our crew as well, was the

intervention of the humpback whale. Scientists are scratching their

heads trying to work out why this behaviour took place. I've been

speaking to scientists and marine ecologists on Thursday's show I

spoke to Alissa Shulman Janiger, she's a whale researcher who is

also an eyewitness. She was in the boat. She has subsequently sent us

this photograph of a humpback whale that was part of that very

intervention. Now if you look at the humpback's fluke, you'll see

those marks along the top and the notch along the tail. They are

scarring from a killer whale attack when the humpback was a calf. They

can identify that. Her theory is that this was some sort of revenge

intervention. The interesting thing about that humpback is that earlier,

before the attack, it was three- and-a-half miles away. So it

definitely moved on in. The natural history unit has witnessed hump

backs intervening before as well. In the Antarctic they witnessed a

humpback intervening on the attack of a seal. Killer whales circled an

ice floe intent on getting the seal off the ice. There they are again,

the hump backs, popping up, appearing to protect the seal. What

you see now is quite extraordinary, because it looks as if the humpback

is popping its flipper around and under the seal to protect it, quite

extraordinary. Robert Pittman is a marine ecologist. He also has

theories about this intervention. One of his theories is that the

hump backs are attracted to the vocalisation of the orcas during

this attack. They're silent when they hunt, but when they feed

they're very vocal. That could attract the hump backs. His other

theory is simply, I'm not sure that I'm with him, hump backs are a bit

silly. He says they're the grazers of the sea and he puts them half a

step above a cow. Not sure if we all as a nation agree with that.

I'm a fan of the humpbacks. Of course, our crews are out there in

the waters now keeping an eye on everything that's happening.

They're all along the coast and already, we've got news of four

other attacks along a 400-mile stretch of coastline between Los

Angeles and San Francisco. We've got another attack in LA. Two at

Big Sur, south of Monteray and one in half moon bay near San Francisco.

As and when we get any more news on any of the grey whales migrating,

we'll let you have it. Remember, it's a bump -- bumper year for the

kaufz. More than a thousand are heading towards their feeding

waters in the Arctic. Let's hope that more of them make it than last

year as well. Half a step above a cow? I think

I'd be wounded in I were a humpback whale. This is quite an opportunity,

earlier on this evening, we found out despite our best efforts to

identify her, Moja's mum isn't Tamu after all. We thought she was a

lioness that the BBC filmed six years ago. Other experts have said

probably not. That means she's without a name. Naming lions is

pretty important for those studying them. We're calling on your help

with this. Weed a like you to help us find a name for her. We need a

name that renects her personality. We've learned a lot about her.

She's brave, strong, courageous and resourceful. We want a name to

reflect all of that. Your suggestions please Facebook and

Twitter. The experts will choose theirs once they've come up with

your suggestions. Naming a lion seriously say big honour. Let's

have your suggestions for it. We have time before we go, I want

to bring you pictures that Sophie filmed on the way to film some

lions. Here they are. If you think of hippos being big, cuddly fat

things, that's proof that they're really not. We reckon they're

probably two males. It's probably a territorial disputes. They can open

their mouths four feet wide. Those huge teeth can cause pretty

horrible damage to one another. That's why we're advised to keep

out of the way of them. I believe we have footage of a leopard as

well seen skulking around these parts this evening. There we go.

That say leopard out there. It is all going on, yeah, there you go.

That's a beautiful, elusive thing to see. I'm hoping to see one of

those whilst I'm here in the Masai Mara. We're very nearly out of time

now. I will say, it's a lovely, dry evening. One last thing before

we'll go probably. Meanwhile there are lots of stories to keep on top

of. Here's a few ideas of what's coming up in the next show: We find

out how limb pink foot's mum copes in the aftermath -- Little Pink

Foot's mum copes after her treatment. We bring you the latest

-- latest on Aster, will she be given her marching orders? And will

brave meerkat Ernesto survive his snake bite? You can keep up to date

with the Planet Earth Live stories on the web, Twitter and Facebook.

On Wednesday, I'm going to be joined in the Northwoods of

Minnesota by the bear man himself, the man who makes all of this

possible here in the Northwoods, Dr Lynn Rogers. He's got a PhD in

bears. He's a zooologist and he is the only man in the world that

walks with wild black bears. He has some of the cutest friends in the

world and he'll be sitting next to me on a log right here on Wednesday.

We'll see you and we'll meet him then.

I'm looking forward to that. We're halfway through this incredible

adventure now. I'd like to say, thanks to all of our crews, they're

out there in the field throughout the world filming the stuff that

brings you some incredible stories on the strifes and troubles facing

animals in the wild right now. animals in the wild right now.

That's pretty much it this evening. Remember the adventure goes on. It
