0:00:02 > 0:00:06On Roar today. Something has spooked the pride of lions.
0:00:06 > 0:00:09There's an intruder in their territory.
0:00:09 > 0:00:12Will it escape or will it be cat food?
0:00:12 > 0:00:14Squeak, squeak.
0:00:39 > 0:00:43- Hello and welcome to Roar. I'm Rani. - And I'm Johny.
0:00:43 > 0:00:46Sorry, we're just having a quick game of cards, here.
0:00:46 > 0:00:50- Yes, I win! Snap. Yes.- There's no way... You are such a cheater.
0:00:50 > 0:00:53Rani, I'm not a cheater. That's a cheetah.
0:00:53 > 0:00:57- He's got a point. Let's get on with today's show.- I still won, though.
0:01:00 > 0:01:03There'll be no cheating on today's Roar
0:01:03 > 0:01:05because royalty has arrived at Monkey Temple.
0:01:05 > 0:01:09Caesar and Tiberius, the emperor tamarins.
0:01:09 > 0:01:11But can they pass their exams?
0:01:11 > 0:01:14The cheetah have some learning to do too,
0:01:14 > 0:01:18- as I'll be helping with the stick feed. Wow!- You can see their claws.
0:01:18 > 0:01:20Look at their claws, how long they are.
0:01:20 > 0:01:23And all aboard!
0:01:23 > 0:01:26Me and the gang are sailing on the country's most dangerous lake
0:01:26 > 0:01:30to quiz a keeper about hippos, sea lions and gorillas.
0:01:30 > 0:01:34We're going to get him with this one. Ha-ha-ha!
0:01:42 > 0:01:45I'm here in the big cats section of the park and I'm really excited
0:01:45 > 0:01:48because keeper Stu has a special delivery for me.
0:01:48 > 0:01:51- Hiya, Stu, you all right? - All right.- Good to see you.
0:01:51 > 0:01:54So, I'm guessing that it's a nice, big cake to thank me
0:01:54 > 0:01:55for all my work on Roar.
0:01:55 > 0:01:58Well, it could well be, Johny, but I'm not sure myself.
0:01:58 > 0:02:02I wonder if it's an early birthday present from my mum.
0:02:02 > 0:02:04Right, OK, let's have a look.
0:02:05 > 0:02:11Oh, no. Look at... This is Robo-cam. It's the return of Robo-cam.
0:02:11 > 0:02:12This time, it's Robo Mouse.
0:02:20 > 0:02:23Now, in the past, we've tried it out with the wolves,
0:02:23 > 0:02:25who were a little bit wary of it.
0:02:25 > 0:02:28Then we tried it out with the lions, who just tore it to bits.
0:02:28 > 0:02:31Remember this from the last series of Roar?
0:02:31 > 0:02:33They're coming, quick. A bit faster, guys.
0:02:33 > 0:02:38They're going to get him. No, no, no, no! Ha! No!
0:02:38 > 0:02:39They've got Robo Zebra.
0:02:41 > 0:02:43What we going to be doing with Robo Mouse?
0:02:43 > 0:02:46I think we're going to see if the cubs are interested.
0:02:46 > 0:02:48What do you reckon the cubs are going to do?
0:02:48 > 0:02:50Do you reckon they'll be more playful?
0:02:50 > 0:02:53I would say they'd be more playful, yeah.
0:02:53 > 0:02:57Now, this sounds like fun, but there is a real reason for doing this.
0:02:57 > 0:03:00We want to see how the pride hunt and how the cubs behave.
0:03:00 > 0:03:03Look at this, they are really interested.
0:03:03 > 0:03:05It's like when you see a cat at home
0:03:05 > 0:03:07and you've got a little toy and they're crouching
0:03:07 > 0:03:10and they're really slow, then they're ready to pounce.
0:03:10 > 0:03:13They might go for this. Let me get my steering right.
0:03:13 > 0:03:15I can see that the team have been hard at work
0:03:15 > 0:03:18in developing Robo-cam. This year, we've got a new camera.
0:03:18 > 0:03:21We should get some really good shots of the lion cubs.
0:03:21 > 0:03:23Will that be nice for you to see?
0:03:23 > 0:03:27It's always nice to see them from a different perspective and angle.
0:03:27 > 0:03:31Join us later on in the show to see this exciting game of cat and mouse.
0:03:31 > 0:03:33I think they're going to go for this.
0:03:43 > 0:03:45Down at Monkey Temple,
0:03:45 > 0:03:49the family of ten common marmosets have settled in really well.
0:03:49 > 0:03:52They're friendly. Sometimes too friendly.
0:03:52 > 0:03:56And there have already been two gorgeous babies born.
0:03:56 > 0:04:00The little monkeys spend their day running wild
0:04:00 > 0:04:03around their open-top enclosure, playing and feeding.
0:04:03 > 0:04:07They think they own the place, which they do. But not for much longer.
0:04:07 > 0:04:11Because some new monkeys have just arrived
0:04:11 > 0:04:14and Roar has been called up to be the first to meet them.
0:04:14 > 0:04:17Their keeper is Jo Hawthorn.
0:04:17 > 0:04:19We have two brand new arrivals at Longleat.
0:04:19 > 0:04:23They arrived last night, would you like to see them?
0:04:23 > 0:04:24OK.
0:04:30 > 0:04:33These extraordinary looking monkeys
0:04:33 > 0:04:35are a pair of Emperor Tamarins.
0:04:35 > 0:04:36Emperor,
0:04:36 > 0:04:39very regal name, but rightfully so,
0:04:39 > 0:04:40because they have that beautiful moustache.
0:04:40 > 0:04:43These are one of my favourites because of their appearance.
0:04:43 > 0:04:45I'm really pleased they're here.
0:04:45 > 0:04:47They come from the forests of
0:04:47 > 0:04:49South America and, in the wild,
0:04:49 > 0:04:51would live high up in the treetops
0:04:51 > 0:04:52with other species
0:04:52 > 0:04:53of tamarins and marmosets.
0:04:53 > 0:04:55Many of these small monkeys
0:04:55 > 0:04:56look quite similar.
0:04:56 > 0:05:01But you'd never mistake an Emperor Tamarin because, well,
0:05:01 > 0:05:03just look at that 'tache.
0:05:03 > 0:05:07The Emperor Tamarin would stand out to all the others
0:05:07 > 0:05:10because they have those lovely whiskers.
0:05:10 > 0:05:13And these two have been given some very fitting names.
0:05:13 > 0:05:15We have two males, here.
0:05:15 > 0:05:19We've decided to call them, or I've decided to call them,
0:05:19 > 0:05:20Tiberius and Caesar.
0:05:20 > 0:05:23Hence the emperor names.
0:05:23 > 0:05:26One of them is two years old and the other is three. Both males.
0:05:28 > 0:05:29They're almost fully grown.
0:05:29 > 0:05:34These guys will never grow to more than 26cm tall.
0:05:34 > 0:05:36The same height as your average domestic cat.
0:05:36 > 0:05:38Meow!
0:05:38 > 0:05:41In the future, they hope to get females too,
0:05:41 > 0:05:44so they can start a breeding programme.
0:05:44 > 0:05:47But, for now, since they have just arrived,
0:05:47 > 0:05:49they'll be kept in an isolation pen.
0:05:49 > 0:05:52They need to get used to the keepers and to make sure
0:05:52 > 0:05:55they are fit and healthy, before going out into the Temple.
0:05:55 > 0:05:59In their time in isolation, because they won't have the outdoor
0:05:59 > 0:06:02world to explore, there'll be lots of enrichment going on.
0:06:02 > 0:06:06The main aim is to keep them really active and keep them
0:06:06 > 0:06:09really stimulated, while they're doing their isolation period.
0:06:09 > 0:06:12They may be in isolation, but that doesn't mean they can relax.
0:06:12 > 0:06:15Because before they're allowed outside,
0:06:15 > 0:06:18they'll have to pass a series of tests.
0:06:18 > 0:06:22And the examiner will be head keeper Darren Beasley.
0:06:22 > 0:06:26Will they pass? We'll find out later on.
0:06:32 > 0:06:34The one thing you can't miss
0:06:34 > 0:06:37when you see an Emperor Tamarind is the moustache.
0:06:37 > 0:06:40It's thought they got their name as a joke
0:06:40 > 0:06:44because a scientist thought they looked like the German Emperor
0:06:44 > 0:06:48Kaiser Wilhelm II, who also had a big 'tache.
0:06:48 > 0:06:50ALL: Now you know!
0:06:53 > 0:06:56What's a baby's favourite snake?
0:06:56 > 0:06:57A rattlesnake.
0:06:57 > 0:07:00Ba-baork. Ba-ba-ba-baork baork.
0:07:00 > 0:07:06What do you give an elephant that is going to be sick?
0:07:06 > 0:07:08Plenty of space.
0:07:08 > 0:07:13Dum-dum-dum-dum-dum-dum da-da-da da-da-da.
0:07:13 > 0:07:18- What do you get if you cross a sheepdog and a rose?- I don't know.
0:07:18 > 0:07:21What do you get if you cross a sheepdog and a rose?
0:07:21 > 0:07:22A collie-flower.
0:07:37 > 0:07:41Back up in Lion Country, and Robo Mouse is ready to run for his life.
0:07:43 > 0:07:46The whole pride is so interested in what we're up to that
0:07:46 > 0:07:49the keepers have decided to let everyone out at once.
0:07:49 > 0:07:52That way, the cubs will learn how to hunt by watching.
0:07:52 > 0:07:54- I'm ready. Stu, are you ready? - I'm ready, Johnny.
0:07:54 > 0:07:58- But the big question is, are the lions ready?- Let's hope so.
0:07:58 > 0:08:02- Shall we release them?- Let's do it. - I can't wait for this. Right, OK.
0:08:04 > 0:08:06Six to Laura.
0:08:06 > 0:08:10So, if we can see, Robo Mouse is going.
0:08:11 > 0:08:15He's going. Oh, look at this, look! They're running straight over.
0:08:15 > 0:08:17I'm going to get some speed up.
0:08:17 > 0:08:21Ha-ha! Oh, no. Look. No, no!
0:08:24 > 0:08:28That was incredible. They came straight over.
0:08:28 > 0:08:31And they've ripped Robo Mouse to shreds already.
0:08:31 > 0:08:33That didn't last two seconds, did it?
0:08:33 > 0:08:38They've ripped the mouse apart, the mouse, sort of, exterior.
0:08:38 > 0:08:42Remind us what that was made out of again.
0:08:42 > 0:08:44The mouse itself was made out of paper mache.
0:08:44 > 0:08:47It's biodegradable. Nothing that's harmful for them.
0:08:47 > 0:08:50- So, it's not going to hurt them. - Yeah.
0:08:50 > 0:08:53Amazingly, our mouse-cam has survived but, typically,
0:08:53 > 0:08:55it's fallen upside down
0:08:55 > 0:08:59and it's only getting good shots of the grass.
0:08:59 > 0:09:02And they've just obviously made the kill. They can't eat Robo Mouse.
0:09:02 > 0:09:05What does it look like they're doing?
0:09:05 > 0:09:07Will they play around with their catch?
0:09:07 > 0:09:10They'll play around with it, get the smells off of it.
0:09:10 > 0:09:13They'll associate that, obviously, it's not food,
0:09:13 > 0:09:15but it still draws their interest.
0:09:15 > 0:09:19- Look at this amazing, who's this that we've got here?- This is Nibilo.
0:09:19 > 0:09:22- He's the main man. - How impressive does he look?
0:09:22 > 0:09:25And what's incredible is, they've all come out to do the hunt.
0:09:25 > 0:09:27Is this what the male lion would do?
0:09:27 > 0:09:30He's just looking around and just watching what's going on.
0:09:30 > 0:09:32In the wild, the females are responsible
0:09:32 > 0:09:35for all the actual hunting, themselves.
0:09:35 > 0:09:36They'll make the kills.
0:09:36 > 0:09:39Then they'll bring it back to the pride lands
0:09:39 > 0:09:43and the male hoards the meat and they distribute it out between themselves.
0:09:43 > 0:09:47I'm just looking at the cubs. Would the cubs, out in the wild,
0:09:47 > 0:09:50watch the adults to learn how to hunt?
0:09:50 > 0:09:53Yeah, they take a bit of a distance on the main hunt.
0:09:53 > 0:09:57But what you would get is, Mum would take them off separately, on her own.
0:09:57 > 0:10:00She would take the cubs off and she would train them to hunt.
0:10:01 > 0:10:05Stu, what is Nibilo doing with that piece of mouse?
0:10:05 > 0:10:08I think he's sitting on the main part of the kill there, isn't he?
0:10:08 > 0:10:12He's got the majority of it, over there. He's not letting go of that.
0:10:12 > 0:10:15He's just stood there, looks sort of gormless.
0:10:15 > 0:10:17What's lovely to see here is
0:10:17 > 0:10:21that the little cub's playing with his dad.
0:10:21 > 0:10:22Nibilo, this big lion,
0:10:22 > 0:10:26has just let the cub take that piece of paper mache, or mouse...
0:10:26 > 0:10:30- Yup.- ..off him. Now, would he ever let another lion cub do that?
0:10:30 > 0:10:34- Or do they have to be his own?- Oh, they would be his own, definitely.
0:10:34 > 0:10:37There's no way in a million years that another lion cub
0:10:37 > 0:10:38would get near him.
0:10:38 > 0:10:43Well, Stu, it looks like Robo Mouse lasted all of two seconds.
0:10:43 > 0:10:46I think it's definitely been destroyed.
0:10:46 > 0:10:50But it's been a great excuse to see the lions hunt together.
0:10:50 > 0:10:52- And I think they've enjoyed it. - I think they have.
0:10:58 > 0:11:02Back up at Monkey Temple, Caesar and Tiberius, the two Emperor
0:11:02 > 0:11:06Tamarins, have spent the past few days getting used to their new home.
0:11:09 > 0:11:12The plan is for them to be able to go outside into the open-top
0:11:12 > 0:11:15enclosure and mix with the common marmosets.
0:11:15 > 0:11:18But there are no cages or bars outside,
0:11:18 > 0:11:22so the monkeys need to be trained to come for food.
0:11:22 > 0:11:26Only when the keepers are happy will they be allowed out into the Temple.
0:11:26 > 0:11:27And today,
0:11:27 > 0:11:31head keeper Darren Beasley is starting their first lesson.
0:11:31 > 0:11:33Cos they're new animals, they're new to us,
0:11:33 > 0:11:36they've got to get used to the way we do things round here.
0:11:36 > 0:11:38They've got to feel comfortable.
0:11:38 > 0:11:41And part of that involves them eating from places
0:11:41 > 0:11:43and locations that we want them to eat from.
0:11:43 > 0:11:47This may look like a normal, wicker basket.
0:11:47 > 0:11:50In fact, this is a very, very good monkey-feeding device.
0:11:50 > 0:11:54So, the idea is, wherever you put this, the monkeys head towards that.
0:11:54 > 0:11:57They'll go, "Look, there's our basket.
0:11:57 > 0:11:59"That means nice food, yum, yum, yum." Off they'll go.
0:11:59 > 0:12:01I presume it's a bit like
0:12:01 > 0:12:03when I was little, I used to hear the ice-cream van.
0:12:03 > 0:12:05Ding-a-ling! All those lovely tunes.
0:12:05 > 0:12:08The kids would go racing after the ice-cream van.
0:12:08 > 0:12:10The monkeys should say, "There's dinner."
0:12:10 > 0:12:13Association, and they'll come down and find something nice.
0:12:13 > 0:12:16It's a case of getting the Emperor Tamarins used to it,
0:12:16 > 0:12:19not scared of it. Know there's some nice food in it.
0:12:20 > 0:12:24The basket is loaded with woodchips and mealworms,
0:12:24 > 0:12:27so they'll have to do a bit of work to find their food.
0:12:29 > 0:12:32But it's the first time they've seen the basket.
0:12:32 > 0:12:33Will they be too nervous to come near?
0:12:40 > 0:12:44Caesar and Tiberius are not convinced it's safe.
0:12:52 > 0:12:55So, they're a little bit more nervous of me than the basket.
0:12:55 > 0:12:57I think I'm going to come out.
0:12:58 > 0:13:00These guys are amazingly agile.
0:13:00 > 0:13:02They weigh only 400g, which is
0:13:02 > 0:13:06the same as a can of baked beans.
0:13:06 > 0:13:09In the wild, they'd hardly ever come down to the ground,
0:13:09 > 0:13:12but jump from branch to branch, deep in the forest,
0:13:12 > 0:13:15using their orangey-brown tail for balance.
0:13:15 > 0:13:17But whilst they may be great jumpers,
0:13:17 > 0:13:19they're still not going for the food.
0:13:20 > 0:13:23Time to try a bit of bribery. Blueberries.
0:13:23 > 0:13:29Blueberries happen to be a very sweet, juicy, tasty fruit.
0:13:29 > 0:13:30All monkeys love them.
0:13:30 > 0:13:34For me, this is the cheeseburger and chips of the monkey world.
0:13:34 > 0:13:37They'll do just about anything for a bit of sweet fruit.
0:13:37 > 0:13:41Caesar seems to be the bravest. Will he be tempted by the blueberries?
0:13:50 > 0:13:51And he's done it!
0:13:55 > 0:13:58Let's see that again. That was a swift manoeuvre.
0:13:58 > 0:13:59And he's got the prize.
0:14:03 > 0:14:08And once Caesar's had a go, Tiberius moves in for his blueberry.
0:14:12 > 0:14:15Then Caesar goes back for seconds.
0:14:17 > 0:14:21That actually went very well. They didn't dive straight into it.
0:14:21 > 0:14:23They're naturally very cautious animals.
0:14:23 > 0:14:27They've got to be cautious, things eat them in the wild.
0:14:27 > 0:14:30I had to resort to emergency blueberries.
0:14:30 > 0:14:31It's just a matter of time now.
0:14:31 > 0:14:35Once they associate the basket to good things, nothing bad,
0:14:35 > 0:14:36we can then move it on.
0:14:36 > 0:14:39Then, what we'll do is, we'll start moving the basket around.
0:14:39 > 0:14:42So they'll come to the basket, wherever it is.
0:14:42 > 0:14:44They've passed the first test.
0:14:44 > 0:14:47But will Caesar and Tiberius be brave enough
0:14:47 > 0:14:50for their next challenge? We'll be back later to find out.
0:14:54 > 0:14:57Now, recently on Roar, we went to South Africa to follow
0:14:57 > 0:15:01the story of six young cheetah that were coming to Longleat
0:15:01 > 0:15:06to start a new breeding programme for this threatened species.
0:15:06 > 0:15:09Cheetah are the world's quickest land animal.
0:15:09 > 0:15:12They can accelerate faster than most sports cars,
0:15:12 > 0:15:15doing nought to 16 miles an hour in three seconds.
0:15:15 > 0:15:21And their top speed is around 70 miles an hour for short distances.
0:15:21 > 0:15:24The park's cheetah have arrived safely
0:15:24 > 0:15:26and are now in quarantine, up in their new house.
0:15:28 > 0:15:31Now, I'm with deputy head of section Bob, and I am in the
0:15:31 > 0:15:35quarantine section for the cheetahs, and I believe I have to dip my feet.
0:15:35 > 0:15:37- You do.- Why am I dipping my feet?
0:15:37 > 0:15:40My feet are perfectly clean and my shoes are lovely.
0:15:40 > 0:15:42Well, because they're in quarantine,
0:15:42 > 0:15:45we don't want to bring any diseases into them.
0:15:45 > 0:15:46And we don't want to take any out.
0:15:46 > 0:15:49That's why we've got our lovely jackets on.
0:15:49 > 0:15:52- But the gloves, that's a special treat, isn't it?- It is.
0:15:52 > 0:15:55Because we are going to stick feed the cheetahs.
0:15:55 > 0:15:59So, Bob, you said we're going to do a stick feed. What does this mean?
0:15:59 > 0:16:02It means that we've got some small chunks of meat, here.
0:16:02 > 0:16:03- Right.- A couple of sticks.
0:16:03 > 0:16:07We actually stab the meat and just pass it through to them.
0:16:07 > 0:16:10Now, this is not how you normally feed them, is it?
0:16:10 > 0:16:14No, this as an easy way of being able to get medication into them.
0:16:14 > 0:16:18You hide little tablets, worming tablets, into the chunks of meat.
0:16:18 > 0:16:21What we do is get his attention, he'll come over.
0:16:21 > 0:16:25- Come on, mate. Oh, look.- And this is Max, isn't it?- This is Max.
0:16:25 > 0:16:27- He looks so gentle. - He's ever so gentle.
0:16:27 > 0:16:30You're used to looking after the big cats, aren't you?
0:16:30 > 0:16:34And these aren't big cats, cheetahs. So, what's the difference?
0:16:34 > 0:16:36Apart from the size,
0:16:36 > 0:16:39- these are designed for speed more than anything.- Right.
0:16:39 > 0:16:43Because they take on little antelope, gazelles, whatever,
0:16:43 > 0:16:45they've got to be able to keep up with them.
0:16:45 > 0:16:48I think Max has had a good fill, is that
0:16:48 > 0:16:50what he's saying when he's squeaking away to me?
0:16:50 > 0:16:53I think he's just saying he wants some more.
0:16:53 > 0:16:55We can't give it all to him,
0:16:55 > 0:16:58so we'll go and do his little mate here, next door.
0:16:58 > 0:17:00- Come on.- Wow! - You can see their claws.
0:17:00 > 0:17:02Look at their claws, how long they are.
0:17:02 > 0:17:07- Look at them!- Fantastic, isn't it? - Those claws, are they good climbers?
0:17:07 > 0:17:11- Well, they do climb trees.- Yeah. - Well, jump up trees.
0:17:11 > 0:17:13And they're very good at staying in trees.
0:17:13 > 0:17:17Seeing as they run so fast, then they can grip.
0:17:17 > 0:17:22It's like having running spikes on. If you're an athlete,
0:17:22 > 0:17:26you would have spikes in your shoes to grip the ground.
0:17:26 > 0:17:28That's exactly the same with them.
0:17:28 > 0:17:33Look at that! And they're light, aren't they? They just seem.
0:17:33 > 0:17:34- Oh-ha-ha!- Good boy.
0:17:35 > 0:17:40You know, Bob, when I see Casey reaching up here, he's so big.
0:17:40 > 0:17:42- Is he fully grown? - He is fully grown, yeah.
0:17:42 > 0:17:47He's just over two now, so he won't get much bigger.
0:17:47 > 0:17:52So, are they at the right age then to now start families?
0:17:52 > 0:17:56They could do. You know, we've got three males, three females.
0:17:56 > 0:17:59Our hopes are to breed from them.
0:17:59 > 0:18:02It's slightly different, with most of our other cats,
0:18:02 > 0:18:05you just let them get on with it.
0:18:05 > 0:18:08With these, you have to do a blind date sort of thing.
0:18:08 > 0:18:10You have to let the male choose the female.
0:18:10 > 0:18:13If we're going to get these guys fit and healthy
0:18:13 > 0:18:16and ready to breed, I think we'd better hurry up with our feeding.
0:18:16 > 0:18:18- What do you think? - I think we'd better.
0:18:33 > 0:18:35It's time for Ask The Keeper,
0:18:35 > 0:18:38which is challenging enough at the best of times.
0:18:38 > 0:18:41But today, keeper John Reynolds is going to be answering
0:18:41 > 0:18:45questions on not one, but the three animals here on the lake.
0:18:45 > 0:18:47The hippo, the gorilla and the sea lions.
0:18:47 > 0:18:51But he's got to be facing the most fearsome animals of all. This lot!
0:18:51 > 0:18:54- John, are you ready? - I'm ready.- Are you sure about that?
0:18:54 > 0:18:56- I'm definitely ready. - OK, he seems ready.
0:18:56 > 0:19:00We're on the move so that we can see as many animals as possible.
0:19:00 > 0:19:03I can hear some sea lions, has anyone got a sea lion question?
0:19:03 > 0:19:05Arrf, arrf!
0:19:05 > 0:19:06What do sea lions eat?
0:19:06 > 0:19:10Ah, well, sea lions generally eat fish.
0:19:10 > 0:19:12We give ours mackerel, herring or sprats.
0:19:12 > 0:19:14I've got some fish here. This is sprats.
0:19:14 > 0:19:16Any of you want to feed the sea lions?
0:19:16 > 0:19:20- Yes.- Yes? There you go.- Is that why they're making this noise, John?
0:19:20 > 0:19:23- Because they're hungry? - They're trying to get your attention
0:19:23 > 0:19:25so you'll feed them.
0:19:25 > 0:19:28- Do you just throw it in? - Just throw it in to them, yeah.
0:19:28 > 0:19:29That's cool, innit?
0:19:33 > 0:19:35Arrf, arrf, arrf!
0:19:35 > 0:19:39- Guys, how cool is that? - Why do sea lions make that noise?
0:19:39 > 0:19:42Why do they, John? Cos it's hurting my ears a little bit.
0:19:42 > 0:19:45They are making that noise cos they want to get your attention.
0:19:45 > 0:19:48It's not just noises they make to try and get your attention.
0:19:48 > 0:19:52Buster knows that if he makes enough noise, people are going to feed him.
0:19:52 > 0:19:54Are sea lions aggressive?
0:19:54 > 0:19:57Not really, no. I'd say they're generally curious, the sea lions.
0:19:57 > 0:19:59It depends on the time of year.
0:19:59 > 0:20:01When you go into the breeding season, or just after
0:20:01 > 0:20:05the sea lions have given birth, then they're a lot more aggressive,
0:20:05 > 0:20:07cos they've got to defend their babies.
0:20:07 > 0:20:10The rest of the time, they're just curious and playful.
0:20:10 > 0:20:12This is quite nerve-wracking,
0:20:12 > 0:20:15cos one of the most fearsome animals at the park,
0:20:15 > 0:20:17apart from you lot, is just over there.
0:20:17 > 0:20:19We've got a hippo. Has anyone got a hippo question?
0:20:19 > 0:20:21Why are hippos so dangerous?
0:20:21 > 0:20:26They're so dangerous because they're very, very territorial.
0:20:26 > 0:20:30In their territory in Africa, they have to defend their food
0:20:30 > 0:20:32and their breeding space.
0:20:32 > 0:20:35They have to be very aggressive to make sure that they stay fit
0:20:35 > 0:20:37and strong and healthy.
0:20:37 > 0:20:39So, they have developed a way of staying healthy,
0:20:39 > 0:20:41by being very, very territorial.
0:20:41 > 0:20:43How big can a hippo grow to?
0:20:43 > 0:20:47These ones we have here, they're about two-and-a-half tonnes.
0:20:47 > 0:20:49But some girls can grow to about three tonnes
0:20:49 > 0:20:52and male bulls can grow to about four tonnes.
0:20:52 > 0:20:54They can get very, very big.
0:20:54 > 0:20:57How big can hippos extend their mouths to?
0:20:57 > 0:21:01A hippo can actually open its mouth to about 150 degrees.
0:21:01 > 0:21:05- So, that's kind of like... That's kind of like that?- Basically, yes.
0:21:05 > 0:21:06Wow, that's pretty scary.
0:21:06 > 0:21:10Definitely wouldn't want to get caught between that mouth.
0:21:10 > 0:21:14So far, keeper John has done brilliantly.
0:21:14 > 0:21:18But we've still got Nico the gorilla to see. And the killer question.
0:21:18 > 0:21:19So, don't go away.
0:21:22 > 0:21:26OK, here's the cheat code you've been waiting for.
0:21:27 > 0:21:30Type that in and see what it gives you.
0:21:30 > 0:21:32New treats, animals or enclosures.
0:21:34 > 0:21:39You'll find the brilliant Roar game on the CBBC website. Happy gaming.
0:21:44 > 0:21:46We're going back up to Monkey Temple now,
0:21:46 > 0:21:50cos it's exam time for Caesar and Tiberius.
0:21:50 > 0:21:53If they're going to be released into the open-topped enclosure,
0:21:53 > 0:21:57the keepers need to know they'll be safe and won't escape.
0:21:57 > 0:22:00The best way to do that is to make sure
0:22:00 > 0:22:03they always come to the food basket.
0:22:03 > 0:22:06They've passed the first test with flying colours.
0:22:06 > 0:22:09But the training is about to go up a level.
0:22:09 > 0:22:13The next stage is that I now need to move the basket so that
0:22:13 > 0:22:17the monkeys actually come towards us and wherever we put the basket.
0:22:17 > 0:22:19And the whole target is that
0:22:19 > 0:22:23when we're eventually outside, I can move this basket around and
0:22:23 > 0:22:26they'll follow it and that's where they'll go to feed and feel safe.
0:22:26 > 0:22:30Darren is fixing the basket in the room next door.
0:22:30 > 0:22:34For Caesar and Tiberius, it's unknown territory.
0:22:34 > 0:22:38But if they're brave enough to go in and feed from the basket, they'll
0:22:38 > 0:22:40have passed their second test
0:22:40 > 0:22:44and be almost ready to go outside. So, it's fingers crossed.
0:22:45 > 0:22:48Caesar's through. Will Tiberius follow?
0:22:51 > 0:22:56Caesar seems to be the braver, or maybe the greedier, of the two.
0:22:57 > 0:23:00But will he go for the basket and pass the test?
0:23:08 > 0:23:10- Caesar has aced it.- Yes.
0:23:14 > 0:23:18And, as ever, Tiberius isn't far behind.
0:23:20 > 0:23:22That went really well.
0:23:22 > 0:23:25You've got to have patience in this game.
0:23:25 > 0:23:28Because these are fragile, tiny little monkeys,
0:23:28 > 0:23:30so they are nervous.
0:23:30 > 0:23:33Marks out of ten for Emperor Tamarins, they've got to get
0:23:33 > 0:23:36a good eight and a half or nine for that, I think.
0:23:36 > 0:23:37Well worth it.
0:23:37 > 0:23:41It shouldn't be long before these two are ready to go outside.
0:23:41 > 0:23:45But for now, they're just enjoying their fruity rewards.
0:23:49 > 0:23:52Me and the gang are out on Half Mile Lake,
0:23:52 > 0:23:54quizzing keeper John about the animals.
0:23:54 > 0:23:56And we've still got one more to see.
0:23:57 > 0:24:00Look at this. Incredible. Nico the gorilla is out there.
0:24:00 > 0:24:04You're looking at one of the oldest gorillas in Europe.
0:24:04 > 0:24:05Have we got any questions for John?
0:24:06 > 0:24:08Can a gorilla swim?
0:24:08 > 0:24:10No, gorillas can't naturally swim.
0:24:10 > 0:24:13If you ever find yourself in the wild
0:24:13 > 0:24:16being chased by a gorilla, find some water and you'll escape.
0:24:16 > 0:24:19They can paddle, they can even wade. You'd have to make sure that
0:24:19 > 0:24:22it was deep enough that they wouldn't want to risk it.
0:24:22 > 0:24:24How big can gorillas grow to?
0:24:24 > 0:24:25Nico, over there,
0:24:25 > 0:24:29he is about as a big as a western lowland would probably get.
0:24:29 > 0:24:31He's just under two metres tall.
0:24:31 > 0:24:36And he probably weighs something just under 30 stone, which is about 320kg.
0:24:36 > 0:24:39What do you reckon? He's done really well, hasn't he?
0:24:39 > 0:24:42He's answered all our questions. But we have got one more question left.
0:24:42 > 0:24:45And that one is the killer question!
0:24:45 > 0:24:47Come on, guys. Gather around.
0:24:47 > 0:24:50Right, we need to ask a question.
0:24:50 > 0:24:54We're going to get him with this one. Ha-ha-ha!
0:24:54 > 0:24:55So, I'm thinking...
0:24:55 > 0:24:58- So, is that a good killer question? - Yeah.- Yeah.
0:24:58 > 0:25:04The killer question, we've got it? Put it there, guys. Oh, yeah!
0:25:04 > 0:25:07- Right, we're ready, John. But are you?- I'm ready.
0:25:07 > 0:25:09OK, well, here it is.
0:25:11 > 0:25:15How many visitors came on this boat during the whole of last year?
0:25:15 > 0:25:19- How many people came on the boat over the whole of last year?- Yes.
0:25:19 > 0:25:23- It was 427,000. - You're saying 427,000.
0:25:23 > 0:25:28- Was that just a wild guess? - That was a rough average, I'd say.
0:25:28 > 0:25:33Ha-ha! That is incredible, because the answer is actually 433,000.
0:25:33 > 0:25:37You were 6,000 out, that's absolutely incredible!
0:25:37 > 0:25:40I'm suspecting that you're a bit of a genius. That's incredible.
0:25:40 > 0:25:44What do you reckon, guys, a thumbs up or a thumbs down for John?
0:25:44 > 0:25:48Got to be thumbs up, all round. You did amazing.
0:25:54 > 0:25:56Elands are Africa's
0:25:56 > 0:25:58biggest antelope.
0:25:58 > 0:25:59A large bull can weigh
0:25:59 > 0:26:00nearly 1,000 kilos
0:26:00 > 0:26:03and stand 1.8m tall at the shoulder.
0:26:03 > 0:26:07But it's not the grown-ups we've come to see today,
0:26:07 > 0:26:10it's the five babies that have been born this year.
0:26:10 > 0:26:14- We're here with their keeper Dan. How they getting on?- Very good.
0:26:14 > 0:26:16They've been out for quite a while now,
0:26:16 > 0:26:19but we're really happy with how they're getting on.
0:26:19 > 0:26:22- Are they there with Mum? - They are, yeah. All our group is out.
0:26:22 > 0:26:26There's mums, babies, dads, and they're all there together.
0:26:26 > 0:26:30Are little ones still dependant on Mum, are they still suckling?
0:26:30 > 0:26:33They are still suckling, but they're also grazing and stuff.
0:26:33 > 0:26:36- So, they're fairly independent. - You can see them all there.
0:26:36 > 0:26:38They're in the middle, why is that then,
0:26:38 > 0:26:41that the little ones are in the middle?
0:26:41 > 0:26:43They tend to hang around in the middle cos
0:26:43 > 0:26:45they've got the bigger ones around them
0:26:45 > 0:26:47so it's a bit of protection, really.
0:26:47 > 0:26:50Protection against predators. Have we got any names yet?
0:26:50 > 0:26:53They've all got names. We're on the letter L this year.
0:26:53 > 0:26:56We have a different letter for every year, cos it's easy to remember
0:26:56 > 0:26:57when they were born.
0:26:57 > 0:27:01And we've got Lance, Lionel, Lorenzo, Louis G and Lamara.
0:27:01 > 0:27:04Congratulations. Looks like they've settled in nicely
0:27:04 > 0:27:06and they're off to go and play happy families.
0:27:06 > 0:27:09Great stuff. Alas, it's time for us to go.
0:27:09 > 0:27:10Before you leave us,
0:27:10 > 0:27:14- why don't you check out what's on the next episode of Roar?- Bye.
0:27:14 > 0:27:18Next time on Roar, there's trouble up in Wolf Wood.
0:27:18 > 0:27:21Frieda the she-wolf is dangerously ill.
0:27:21 > 0:27:24The keepers and the vet will do everything they can to help her.
0:27:24 > 0:27:26But will it be enough?
0:27:28 > 0:27:31Whippet, the tiny boobok owl, is learning how to fly.
0:27:31 > 0:27:34And I'll be there for his very first attempt.
0:27:34 > 0:27:37And Roar ranger Ethan is a keen magician,
0:27:37 > 0:27:40so the sea lions show him a trick or two.
0:27:40 > 0:27:42How to make fish disappear.
