0:00:02 > 0:00:03Today on Roar, to save his life,
0:00:03 > 0:00:06Ujung the gibbon needs an injection every day,
0:00:06 > 0:00:10but how will the keepers get him to co-operate?
0:00:36 > 0:00:39Hello and welcome to Roar. I'm Rani.
0:00:39 > 0:00:41I'm Johny, and we're in the enclosure of the Asian wild dogs,
0:00:41 > 0:00:42also known as dhole.
0:00:42 > 0:00:46They normally hunt during the day and their prey includes rodents,
0:00:46 > 0:00:49sheep, lizards and even water buffaloes.
0:00:49 > 0:00:53In fact, they are capable of hunting down animals ten times their weight.
0:00:53 > 0:00:56That's like me trying to wrestle a saltwater crocodile.
0:00:56 > 0:00:58I don't fancy your chances!
0:00:58 > 0:01:00I think we should get on with the show.
0:01:00 > 0:01:02Let's make it snappy!
0:01:03 > 0:01:04Coming up on Roar -
0:01:04 > 0:01:10cats eat meat, so why is Melindi going bananas for our fruit treats?
0:01:10 > 0:01:13Oooh! She got the whole kebab!
0:01:15 > 0:01:19I'll be catching up with Etana, the biggest little baby in the park.
0:01:19 > 0:01:23And we'll meet the keeper who's learning to talk to the rhinos.
0:01:23 > 0:01:27But will they understand what he's got to say?
0:01:27 > 0:01:29HE GROWLS
0:01:29 > 0:01:30HE MOANS
0:01:30 > 0:01:32HE BURPS
0:01:35 > 0:01:39But first, we're going to the primate section,
0:01:39 > 0:01:43because Oojiang the moloch gibbon has a serious problem.
0:01:43 > 0:01:46These monkeys come from the Indonesian island of Java,
0:01:46 > 0:01:48where they're an endangered species.
0:01:48 > 0:01:52In fact, there's less than 2,500
0:01:52 > 0:01:57in the wild, and just over 100 in captivity.
0:01:57 > 0:02:01So, the collection of moloch is very important.
0:02:01 > 0:02:05Jo Marden is one of the keepers who looks after them.
0:02:05 > 0:02:08This is one of our many moloch gibbon cages and we've come up
0:02:08 > 0:02:12to see Oojiang. He is our dominant adult male in the group.
0:02:12 > 0:02:15He's currently with a mature adult female at the moment,
0:02:15 > 0:02:18and he's fathered lots of children.
0:02:19 > 0:02:22Moloch gibbons naturally live in small family groups,
0:02:22 > 0:02:26and in with Oojiang is his mate Koolon and two of their children.
0:02:28 > 0:02:31The family has always got on well but a few months ago,
0:02:31 > 0:02:34the keepers noticed that there was something wrong with Dad.
0:02:34 > 0:02:38Like with all our primates, we do a daily check
0:02:38 > 0:02:41on what they're eating and drinking.
0:02:41 > 0:02:44We started to noticed something, definitely unusual
0:02:44 > 0:02:46that we hadn't seen before.
0:02:46 > 0:02:51He was quite lethargic during the day and spent a lot of time sleeping.
0:02:51 > 0:02:56His appetite wasn't great and he was drinking a lot as well.
0:02:56 > 0:03:00With gibbons, they get most of their moisture out of their food,
0:03:00 > 0:03:02and it just wasn't really quite right.
0:03:02 > 0:03:06Another bad sign was that, for some reason, Oojiang's family
0:03:06 > 0:03:08began to keep away from him.
0:03:08 > 0:03:11This was strange because moloch gibbons
0:03:11 > 0:03:15normally spend a lot of time grooming each other.
0:03:15 > 0:03:20Our vet team decided to sedate him. He was given a full health check.
0:03:20 > 0:03:24And some blood samples were taken. We found out that he was diabetic.
0:03:24 > 0:03:29Diabetes is a medical condition. It is when the body is failing
0:03:29 > 0:03:34to make enough insulin, and insulin is the chemical the body needs
0:03:34 > 0:03:37to control how much sugar is in the blood.
0:03:39 > 0:03:42Diabetes can be a really serious condition which means
0:03:42 > 0:03:45we have to control the amount of sugar he gets daily.
0:03:45 > 0:03:48If we don't, he can become quite poorly.
0:03:48 > 0:03:50Gibbons eat fruit which contains a lot of sugar
0:03:50 > 0:03:54and one way to control how much sugar gets into Oojiang's blood
0:03:54 > 0:03:57is to control exactly what he eats.
0:03:57 > 0:04:01But that was impossible while the whole family was fed together.
0:04:01 > 0:04:05Before, we weren't able to monitor what he was eating.
0:04:05 > 0:04:07He was still being fed with the group,
0:04:07 > 0:04:11with other members of the family in the shed and outside the shed,
0:04:11 > 0:04:14so we couldn't control what he was getting.
0:04:14 > 0:04:16We decided to completely modify his diet.
0:04:16 > 0:04:20He was getting the amount he should be getting, the right amount,
0:04:20 > 0:04:23and foods that he wasn't allowed, that were high in sugar,
0:04:23 > 0:04:26were kept out of his diet completely.
0:04:26 > 0:04:28As well as a strictly controlled diet,
0:04:28 > 0:04:31Oojiang also needs an injection of insulin
0:04:31 > 0:04:33every single day.
0:04:33 > 0:04:36Trying to think of how you're going to inject a monkey dailly,
0:04:36 > 0:04:37with an injection,
0:04:37 > 0:04:41is pretty difficult and hard to think of, so we had a lot of problems
0:04:41 > 0:04:43to face from the beginning.
0:04:43 > 0:04:48Without insulin, Oojiang would become very ill,
0:04:48 > 0:04:50but how on earth do you get a wild animal
0:04:50 > 0:04:52to have an injection every day?
0:04:52 > 0:04:55We'll be back later to see
0:04:55 > 0:04:58the extraordinary plan the keepers came up with.
0:05:12 > 0:05:16I've popped down to the elephant paddock to meet keeper Tom King
0:05:16 > 0:05:19to have a catch up with this cute elephant right here -
0:05:19 > 0:05:20this is baby Etana.
0:05:20 > 0:05:21How old is she now, Tom?
0:05:21 > 0:05:26- Etana's just over six months old. - Wow. And how's she getting on?
0:05:26 > 0:05:27She's doing very well.
0:05:27 > 0:05:29She's doing everything a little elephant should be.
0:05:29 > 0:05:32Watching what the bigger elephants are doing and, you can see,
0:05:32 > 0:05:35she's got a bit of branch at the moment.
0:05:35 > 0:05:37She's not actually eating anything.
0:05:37 > 0:05:39She's kind of playing with the food.
0:05:39 > 0:05:43Because, obviously, she's still relying a lot on mother's milk.
0:05:43 > 0:05:46How's she getting on with the rest of the elephants?
0:05:46 > 0:05:50Is there any rivalry? There are a few other baby elephants
0:05:50 > 0:05:53that aren't too much older than Etana.
0:05:53 > 0:05:56We've got Uzuri, who's standing with Etana at the moment.
0:05:56 > 0:05:58Uzuri's 15 months old.
0:05:58 > 0:06:00They bond and interact very well.
0:06:00 > 0:06:03But that's all part of elephant life.
0:06:03 > 0:06:05Elephants can go to a ripe old age.
0:06:05 > 0:06:08How long does it take them to get to adolescence?
0:06:08 > 0:06:13To adolescence, you are looking at, for bulls, about eight or nine,
0:06:13 > 0:06:16and females, probably slightly younger.
0:06:17 > 0:06:21But the way an elephant grows, it grows up, then stops,
0:06:21 > 0:06:23then out, then stops, and so on.
0:06:23 > 0:06:29If you look at all the elephants, the highest point on the young calves
0:06:29 > 0:06:32are always going to be their backbone.
0:06:32 > 0:06:37If you look at the adults, the highest point is their shoulder,
0:06:37 > 0:06:43so a little calf like Uzuri, at nearly 16 months now,
0:06:43 > 0:06:46she's still very much going in this growth spurt stage.
0:06:46 > 0:06:50What does the future hold for Etana? Will she move on from this herd,
0:06:50 > 0:06:51or stick around?
0:06:51 > 0:06:58With female elephants, you can keep them in the group,
0:06:58 > 0:07:01because it's a matriarchal structure.
0:07:01 > 0:07:04So, in the wild, females will stay with the group all their life.
0:07:04 > 0:07:09They don't have to move off, whereas a male elephant is different.
0:07:09 > 0:07:12Naturally, they'll be pushed out of the group.
0:07:12 > 0:07:14Male elephants, we have to look at moving them on.
0:07:14 > 0:07:16Females can stay for the rest of their lives.
0:07:16 > 0:07:20I can't wait to see Etana grow throughout the series.
0:07:20 > 0:07:25- Thanks for letting us get so close to them.- That's all right, Johny.
0:07:39 > 0:07:42It's Ask The Keeper time and I've crammed my truck full
0:07:42 > 0:07:45of bright young brain-boxes and brought them to
0:07:45 > 0:07:49the African Experience to test the knowledge of Bob Saville.
0:07:49 > 0:07:52and see if he knows all there is to know about his pesky peckers,
0:07:52 > 0:07:55and I'm talking about the ostriches right behind him now.
0:07:55 > 0:07:58- Bob, you're not getting pecked away? - No, not too bad.
0:07:58 > 0:08:03It's very windy up here so we'll start with the questions.
0:08:03 > 0:08:05All right, guys, fire them at Bob.
0:08:05 > 0:08:07How big are their eggs?
0:08:07 > 0:08:11Well, they're like a small watermelon.
0:08:11 > 0:08:15They're about that size. The same shape as an ordinary egg
0:08:15 > 0:08:17but about 15 chicken eggs in each one.
0:08:17 > 0:08:20So about that big.
0:08:20 > 0:08:21What do ostriches eat?
0:08:21 > 0:08:25Out in the wild they eat seeds and berries, grass.
0:08:25 > 0:08:27Basically, they do exactly the same thing here.
0:08:27 > 0:08:31We also give them a few nuts to keep them going as well.
0:08:31 > 0:08:33How many years has ostriches been living?
0:08:33 > 0:08:36They're probably one of the oldest sorts of animals.
0:08:36 > 0:08:38They haven't changed much. If you look at their feet,
0:08:38 > 0:08:41they're basically the same as dinosaurs' feet.
0:08:41 > 0:08:43Long big toes with a big claw on the end.
0:08:43 > 0:08:45Do they build nests?
0:08:45 > 0:08:48No, they basically... Loose ground.
0:08:48 > 0:08:51We normally give them a big pile of sand.
0:08:51 > 0:08:53They roll around and make a little depression.
0:08:53 > 0:08:55They don't build nests.
0:08:55 > 0:08:56How fast can they go?
0:08:56 > 0:08:58About 45 miles an hour.
0:08:58 > 0:09:01They don't look like they're running fast
0:09:01 > 0:09:03but their strides get longer and longer.
0:09:03 > 0:09:07They do travel remarkably fast when they want to.
0:09:07 > 0:09:09It's time for your Killer Question.
0:09:09 > 0:09:13We have to decide what it is. Give us a moment.
0:09:13 > 0:09:15What do you think, then?
0:09:19 > 0:09:20OK. That's too hard!
0:09:22 > 0:09:23Right, OK.
0:09:24 > 0:09:26Right, OK.
0:09:26 > 0:09:29Now, how long would it take for an ostrich to run
0:09:29 > 0:09:32from the two furthest points in the country -
0:09:32 > 0:09:34Land's End to John O'Groats?
0:09:34 > 0:09:39You know the distance, you know how fast they can run.
0:09:39 > 0:09:40So, how long would it take them?
0:09:42 > 0:09:45Shall I help you out a little bit at all?
0:09:45 > 0:09:47Yes, if you've got a calculator and a road map!
0:09:47 > 0:09:51The distance is 970 kilometres.
0:09:51 > 0:09:54970 kilometres?
0:09:54 > 0:09:55That's a great help(!)
0:09:55 > 0:09:59How many miles, cos I'm an old-fashioned person?
0:09:59 > 0:10:02You've got to move with the times, Bob Saville!
0:10:02 > 0:10:05- Shall we tell him the answer? - Yes, tell me the answer!
0:10:05 > 0:10:09The top speed an ostrich can run is 65 kilometres.
0:10:09 > 0:10:14If it was going to 970 kilometres that would take it 14 hours, Bob.
0:10:14 > 0:10:19- Wow!- I've got to say, ostriches, that is very impressive.
0:10:19 > 0:10:22Bob, it looks like maths isn't your strong point,
0:10:22 > 0:10:24but how did you do on the rest?
0:10:24 > 0:10:27Guys, what do you think? Thumbs up or thumbs down?
0:10:27 > 0:10:30Mr Saville, it's thumbs up all around.
0:10:30 > 0:10:32APPLAUSE
0:10:35 > 0:10:38What does an ant eat when it's ill?
0:10:38 > 0:10:39Antibiotics!
0:10:39 > 0:10:42Ooohh, ooh, ooh!
0:10:42 > 0:10:44# Bonkers! #
0:10:44 > 0:10:45Ooohh, ooh, ooh!
0:10:45 > 0:10:48There's a policeman and a zookeeper chatting at the zoo.
0:10:48 > 0:10:50And the policeman said...
0:10:50 > 0:10:54"One of your elephants is chasing a man on a bike."
0:10:54 > 0:10:56And the zookeeper said...
0:10:56 > 0:11:00"Nonsense, none of my elephants can ride a bike!"
0:11:01 > 0:11:03Cluck, cluck, cluck!
0:11:03 > 0:11:05What's big and grey and red?
0:11:05 > 0:11:07I dunno.
0:11:07 > 0:11:09A sunburnt elephant.
0:11:09 > 0:11:11HE LAUGHS
0:11:12 > 0:11:14Boo!
0:11:25 > 0:11:29Rani tells me that whenever new babies are born at the park,
0:11:29 > 0:11:31she's the first to catch a glimpse.
0:11:31 > 0:11:33Today, I'm the lucky one.
0:11:33 > 0:11:37Keeper Helen Rose is going to introduce me to the capybara babies.
0:11:37 > 0:11:38Where are they?
0:11:38 > 0:11:41They're in the paddock here. They can me elusive and shy.
0:11:41 > 0:11:43Johny, if you can put that coat on,
0:11:43 > 0:11:46cos normally I go in with my colleagues.
0:11:46 > 0:11:48Hopefully they'll come over.
0:11:48 > 0:11:50A cunning disguise! Brilliant.
0:11:50 > 0:11:53Right, let's go for it! Bring it on.
0:11:53 > 0:11:57OK, Helen. The crew are over there. Can you see us, guys?
0:11:57 > 0:11:59Right, OK.
0:11:59 > 0:12:01Why are these guys so shy?
0:12:01 > 0:12:05Um, to be honest, it's probably because a natural instinct.
0:12:05 > 0:12:07Any animal should be aware of humans.
0:12:07 > 0:12:10And what kind of predators would they have in the wild?
0:12:10 > 0:12:15Yeah, any sort of cats, snakes. Stuff like that.
0:12:15 > 0:12:18If we just go over here...
0:12:18 > 0:12:21And just get to their level, Johny.
0:12:21 > 0:12:23All right, then, kids?
0:12:25 > 0:12:27I can't promise they'll come over.
0:12:27 > 0:12:29If I wasn't here, would they come over?
0:12:29 > 0:12:32I think yes.
0:12:32 > 0:12:35They do get to know us and trust us.
0:12:35 > 0:12:38Hopefully the coat might work, you never know.
0:12:38 > 0:12:40Um... Come on, then!
0:12:40 > 0:12:45- How old are the little ones? - They're about three weeks.
0:12:45 > 0:12:48Come on, then!
0:12:48 > 0:12:51- What have we got in the bucket? - There are the babies.
0:12:51 > 0:12:54- Aw, they're tiny! - Come on, then.
0:12:54 > 0:12:58- They're coming over.- If we're quiet, I think they'll walk past.
0:12:59 > 0:13:01So the little ones are going past here now.
0:13:01 > 0:13:03They do seem really shy.
0:13:03 > 0:13:07I'm sorry to say they're not going to come over today.
0:13:07 > 0:13:10So why don't we leave them the bucket and food.
0:13:10 > 0:13:12It's been great to see the babies, anyway.
0:13:12 > 0:13:15- At least I got to see them before Rani did!- Exactly.
0:13:24 > 0:13:27When Ujung the moloch gibbon was diagnosed with diabetes
0:13:27 > 0:13:31the biggest problem the keepers faced
0:13:31 > 0:13:34was how to inject insulin every day.
0:13:34 > 0:13:38Jane, the park's vet, was keeping a close eye on his health.
0:13:38 > 0:13:43Obviously, we couldn't inject Ujung right at the start when he needed it.
0:13:43 > 0:13:46He had to become used to having an injection.
0:13:46 > 0:13:50There were a couple of months where he was not receiving the injection
0:13:50 > 0:13:53so he lost a lot of weight and condition.
0:13:53 > 0:13:55We were quite concerned about him.
0:13:55 > 0:14:00Gibbons are rather shy so catching or shooting him with a blow dart
0:14:00 > 0:14:03every day would be very stressful.
0:14:03 > 0:14:08They needed to find a way to get Ujung to co-operate.
0:14:08 > 0:14:11Jo Marden helped work out a plan.
0:14:11 > 0:14:14I tried to get him used to being around keepers.
0:14:14 > 0:14:17We wanted Ujung to eventually present his arm to us
0:14:17 > 0:14:19where we'd be able to inject him.
0:14:19 > 0:14:22We went through a few methods of trying to get him to do that.
0:14:22 > 0:14:24Eventually we found one method that worked
0:14:24 > 0:14:26and we've gone from there, really.
0:14:27 > 0:14:32For several months the keepers worked hard to win Ujung's trust.
0:14:32 > 0:14:35First they had to train him to come up close
0:14:35 > 0:14:38using a food treat as a reward.
0:14:38 > 0:14:41Then they got him to put his hand through a hole.
0:14:41 > 0:14:43Good boy!
0:14:43 > 0:14:46And gradually, little by little,
0:14:46 > 0:14:49they trained him to put not just his hand
0:14:49 > 0:14:53but his whole arm through the hole and right into a tube.
0:14:53 > 0:14:56We'd been training Ujung to present his arm.
0:14:56 > 0:15:00He puts his arm down a tube, a target which he has to hold on to.
0:15:00 > 0:15:04And that's when we inject him.
0:15:04 > 0:15:06Arm. Hold.
0:15:06 > 0:15:09The tube has a slot cut out at the top.
0:15:09 > 0:15:11Good boy!
0:15:11 > 0:15:12Good boy.
0:15:12 > 0:15:14When Ujung has his arm down the tube...
0:15:14 > 0:15:16Come on, then. Arm!
0:15:16 > 0:15:17Hold.
0:15:17 > 0:15:20- ..Jo can give that vital injection. - Good boy!
0:15:20 > 0:15:24When we train him, we don't use too sugary foods.
0:15:24 > 0:15:28At the moment we're using pears, something he's used to.
0:15:28 > 0:15:33When he's rewarded, he's rewarded with more things he likes.
0:15:36 > 0:15:38The primate section has done a fantastic job.
0:15:38 > 0:15:41I'm getting the insulin into Ujung's arm.
0:15:41 > 0:15:44I can diagnose but I can't inject every day.
0:15:44 > 0:15:45Really, that was down to them
0:15:45 > 0:15:48and I'm very pleased and they've done a great job.
0:15:50 > 0:15:54From being worried about what we were going to do
0:15:54 > 0:15:57about injecting him to now,
0:15:57 > 0:15:59he couldn't be any better with training
0:15:59 > 0:16:01and adapting to the way we wanted him to be.
0:16:01 > 0:16:04So yeah, it's really looking good.
0:16:04 > 0:16:07So, you see, patience pays off!
0:16:09 > 0:16:13As soon as he had three or four months of injections,
0:16:13 > 0:16:16you could notice the change. You could see that he felt better.
0:16:16 > 0:16:19He's putting his weight back on gradually which is good.
0:16:19 > 0:16:20His behaviour is picking up.
0:16:20 > 0:16:24We are able to get urine samples and measure the glucose,
0:16:24 > 0:16:26which shows how controlled his diabetes is.
0:16:26 > 0:16:29They are steadily getting better.
0:16:30 > 0:16:34Although Ujung is only nine years old, he's got a lot longer to live.
0:16:34 > 0:16:37Hopefully we've diagnosed it quite early
0:16:37 > 0:16:40so we can do something about that quite quickly
0:16:40 > 0:16:43and injecting him daily will prolong the time he's got.
0:16:43 > 0:16:48Hopefully he can continue being a successful breeding male.
0:16:48 > 0:16:51As Ujung recovered from the worst of his illness,
0:16:51 > 0:16:53his relationship with his family changed.
0:16:53 > 0:16:56Where once he was tired and uninterested,
0:16:56 > 0:16:58now he plays with his kids.
0:16:58 > 0:17:01He and his partner can often be seen grooming,
0:17:01 > 0:17:05and the keepers suspect she might even be pregnant,
0:17:05 > 0:17:09which is pretty good news for an endangered species.
0:17:15 > 0:17:19If you're a Roar gamer, you'll know what to do with this.
0:17:20 > 0:17:23That's today's cheat code.
0:17:23 > 0:17:26If you're not a Roar gamer, why not?
0:17:26 > 0:17:28It's easy to find on the CBBC website
0:17:28 > 0:17:30and it's great fun, so no excuses!
0:17:41 > 0:17:45Now, the majority of carnivores only eat meat,
0:17:45 > 0:17:46but there is one cat species
0:17:46 > 0:17:50that likes to eat a little bit of fruit and grass.
0:17:50 > 0:17:54So, Ben, tell me, is Melindi the serval trying to get a good balance
0:17:54 > 0:17:57of vitamins and nutrients by eating fruit as well?
0:17:57 > 0:18:01Well, in the wild she would, but we've never tried it here,
0:18:01 > 0:18:02so this will be the first time.
0:18:02 > 0:18:05I actually thought this was a crazy idea,
0:18:05 > 0:18:07so in the wild she'd actually eat fruit?
0:18:07 > 0:18:10I thought these were great hunters and that's what they do,
0:18:10 > 0:18:13go and catch their animals, meat and maybe a bit of fish.
0:18:13 > 0:18:15Well, I'm sure if times are hard,
0:18:15 > 0:18:18you know, meat's a bit scarce and they come across some fruit,
0:18:18 > 0:18:22I'm sure they'll give it a good old nibble, just to see them through.
0:18:22 > 0:18:25OK, then, so you've got a little fruit kebab thing going on here
0:18:25 > 0:18:26on a string, and some veg as well.
0:18:26 > 0:18:29There's carrot there, banana, apple and a bit of peach.
0:18:29 > 0:18:32But Melindi's disappeared at the moment.
0:18:32 > 0:18:35Tell me, where is Melindi from, in the wild?
0:18:35 > 0:18:36- She's from Africa.- Africa?
0:18:36 > 0:18:40So which kind of area is she living in that she would find fruit?
0:18:40 > 0:18:43They mainly come from the grass regions, the savannah areas.
0:18:43 > 0:18:47But in Africa, there's lots of plantations that grow fruit
0:18:47 > 0:18:51and things like that, so she'll come across fruit fairly easily.
0:18:51 > 0:18:54She seems to be going for this. I don't know whether it's because
0:18:54 > 0:18:57she just likes to play. She is really playful.
0:18:57 > 0:19:00Yeah, she's hand raised, so obviously she's very playful.
0:19:00 > 0:19:04Let's just see - is she interested in taking a little sniff?
0:19:04 > 0:19:07Sniff of carrot, banana? Not too interested!
0:19:07 > 0:19:10- Doesn't seem that way.- But you said this is the first time.
0:19:10 > 0:19:12Yeah, it's one of those things.
0:19:12 > 0:19:14To start with, I think she just thinks it's a toy.
0:19:14 > 0:19:16She doesn't think it's food.
0:19:16 > 0:19:18Obviously it's the first time she's come across it,
0:19:18 > 0:19:21so it's one of these things that we'll have to keep trying
0:19:21 > 0:19:23until one day she might have a nibble.
0:19:24 > 0:19:28Ooh-hoo! She's got the whole kebab!
0:19:28 > 0:19:31- She was good there, Ben, wasn't she? - Very good.
0:19:31 > 0:19:34- Great bit of paw action! - Yeah. Very agile.
0:19:34 > 0:19:38In the wild, what kind of food would she hunt? What prey?
0:19:38 > 0:19:43Birds, rodents, reptiles, insects - slugs and things like that.
0:19:43 > 0:19:45They eat pretty much anything.
0:19:45 > 0:19:48- Slugs?- Yeah, anything they can find, they'll eat.
0:19:48 > 0:19:50She seems to enjoy playing with her fruit kebab,
0:19:50 > 0:19:53but at the moment she's not too interested in eating it.
0:19:53 > 0:19:57Shall we leave it here and maybe she can have a little nibble later?
0:19:57 > 0:20:00Yeah, it might attract slugs and things like that for her to eat!
0:20:00 > 0:20:03- Well, if it attracts slugs, she can eat them!- Exactly!
0:20:03 > 0:20:05All right, thanks very much, Ben.
0:20:09 > 0:20:13Over at the gorilla house, something sad has happened.
0:20:13 > 0:20:17Kijo, the big male silverback, has died unexpectedly.
0:20:17 > 0:20:22He was leader, father and grandfather to a large family
0:20:22 > 0:20:24and just 34 years old.
0:20:24 > 0:20:27In captivity, gorillas often live well into their 40s,
0:20:27 > 0:20:29so it was a big shock for all the keepers,
0:20:29 > 0:20:32amongst them head of section Lorna Walness.
0:20:35 > 0:20:37Unfortunately, we've had some bad news.
0:20:37 > 0:20:41We lost Kijo who was the silverback in this group.
0:20:41 > 0:20:43He died quite suddenly of a heart attack.
0:20:43 > 0:20:45It's left us quite devastated.
0:20:45 > 0:20:50Kijo was much loved by all his keepers, particularly Laura Bentley.
0:20:50 > 0:20:54Us keepers say that you shouldn't really have favourites,
0:20:54 > 0:20:58but it is hard not to and, um, yeah, Kijo had a big place in my heart.
0:20:58 > 0:21:00He was definitely one of my favourites,
0:21:00 > 0:21:02if definitely my favourite gorilla.
0:21:02 > 0:21:06He was a good silverback, he looked after his group.
0:21:06 > 0:21:10He was very well respected in the group. He had lots of offspring,
0:21:10 > 0:21:12he was one of our most important silverbacks,
0:21:12 > 0:21:16as far as the collection today. He had a big part in playing in that.
0:21:17 > 0:21:21And there's a surprising twist to this story.
0:21:21 > 0:21:26It's sad that Kijo's gone, but he has left something hopeful behind.
0:21:26 > 0:21:29We have got one bit of good news, which is nice for this group.
0:21:29 > 0:21:33Dihi, one of Kijo's females, is pregnant.
0:21:33 > 0:21:37So that's really good and it will also be Kijo's last,
0:21:37 > 0:21:40so all in all, it'll be a very special gorilla,
0:21:40 > 0:21:42just like their dad.
0:21:42 > 0:21:45It is a terrible thing that's happened.
0:21:45 > 0:21:49Obviously, we're all still really sad about losing Kijo.
0:21:49 > 0:21:51But life does go on.
0:21:51 > 0:21:56The group that he's left behind still needs to move on, and they will.
0:21:56 > 0:22:00Another silverback eventually will come in and, um, you know,
0:22:00 > 0:22:03they'll move on like the rest of us.
0:22:03 > 0:22:08But, um, hopefully Dihi's baby will be a nice reminder of Kijo
0:22:08 > 0:22:10and, um, you know, things will be all right.
0:22:12 > 0:22:15We'll be keeping our fingers crossed for Dihi,
0:22:15 > 0:22:17and when that baby arrives,
0:22:17 > 0:22:20we'll be there to show you what happens to Kijo's last child.
0:22:31 > 0:22:34The keepers at the park do everything in their power
0:22:34 > 0:22:37to make sure the animals they look after have whatever they need
0:22:37 > 0:22:41to keep them happy and healthy. But, imagine how much easier their jobs
0:22:41 > 0:22:45would be if they could just ask the animals what they want.
0:22:45 > 0:22:48Well, one keeper has been working on just that.
0:22:49 > 0:22:52Hi, I'm Nick and I can talk to the rhinos.
0:22:52 > 0:22:56In the past, we've seen that Nick will stop at nothing
0:22:56 > 0:22:59to learn more about his black rhinos.
0:22:59 > 0:23:04He's even tried out their mud wallow. But do they really talk?
0:23:04 > 0:23:08Communication is really important to rhinos. They do it in various ways,
0:23:08 > 0:23:11through squeaks, squeals, roars and snorts.
0:23:11 > 0:23:14So they make different sounds,
0:23:14 > 0:23:17but can we tell what those noises really mean?
0:23:17 > 0:23:19One of the commonest noises you'll hear,
0:23:19 > 0:23:23certainly when you've got mums and calves together,
0:23:23 > 0:23:26is like a little squeal sound. Sort of a Mmmh, mmhm.
0:23:26 > 0:23:28RHINOS SQUEAL
0:23:28 > 0:23:32It's generally there for the calf to tell the mum everything's OK, really.
0:23:32 > 0:23:34And what other noise do they make?
0:23:34 > 0:23:35HE BURPS
0:23:35 > 0:23:36Charming!
0:23:36 > 0:23:39Sometimes when rhinos are content,
0:23:39 > 0:23:42they may make a gurgling, burping noise.
0:23:42 > 0:23:44BOTH BURP
0:23:46 > 0:23:48What about when they're being aggressive?
0:23:51 > 0:23:55While they're fighting, it'd be a sort of roaring sort of sound.
0:23:55 > 0:23:58A rrr-rrrargh sort of noise. Almost like a lion.
0:23:58 > 0:23:59IT ROARS
0:23:59 > 0:24:03A bit more guttural and burbly than that, but I can't really do that.
0:24:03 > 0:24:05That aggressive roar...
0:24:05 > 0:24:07Raaaaarrr!
0:24:07 > 0:24:11..is hardly ever heard here in the park, luckily for everyone's ears.
0:24:11 > 0:24:14The rhino's scream is incredibly loud, really.
0:24:14 > 0:24:17They could hear it for over a mile away.
0:24:17 > 0:24:19I mean, we can hear it from across the park.
0:24:20 > 0:24:22So rhinos do make sounds
0:24:22 > 0:24:25that must mean something to other rhinos. But...
0:24:25 > 0:24:29- SQUEAK!- ..what will they think if it's Nick who's doing the talking?
0:24:29 > 0:24:32Mmmh! Mmmh.
0:24:32 > 0:24:35Mmmh.
0:24:35 > 0:24:36Mmmh.
0:24:36 > 0:24:38She doesn't seem too talkative today.
0:24:38 > 0:24:41Clearly, that's not going to work.
0:24:41 > 0:24:44But then rhinos have another way to communicate.
0:24:45 > 0:24:50They leave each other messages in the form of dung.
0:24:50 > 0:24:52Scent-marking round their territories.
0:24:52 > 0:24:55They have several of these around their ranges,
0:24:55 > 0:24:56so they just do their business
0:24:56 > 0:25:00and then they know who's in their area at any one point.
0:25:01 > 0:25:04So, rhinos aren't the chattiest animal around,
0:25:04 > 0:25:07and we can hardly tell what they're saying, anyway.
0:25:07 > 0:25:11But, on the other hand, they seem to understand each other.
0:25:26 > 0:25:27He's tough!
0:25:27 > 0:25:31It's almost the end of the show, but we've found just enough time
0:25:31 > 0:25:33to come and have a tug-o-war with a Siberian lynx, Bill
0:25:33 > 0:25:36and his keeper Rich Langston. Rich, how you doing?
0:25:36 > 0:25:37I'm fine.
0:25:37 > 0:25:41Look at you just chilling out! Rich, we've heard of soap on a rope,
0:25:41 > 0:25:43but meat on a rope? Is this how you normally feed Bill?
0:25:43 > 0:25:46We've done it quite a lot. It means he has to work for it
0:25:46 > 0:25:50and use his strength and paws and teeth and it's just more natural,
0:25:50 > 0:25:51rather than give it to him.
0:25:51 > 0:25:54It's quite tight, cos you can tell he's got strength behind him.
0:25:54 > 0:25:57He's very strong. Is this the kind of food
0:25:57 > 0:25:59that you'd feed him out in the wild? He's loving this!
0:25:59 > 0:26:03Yeah, give him anything and he'll like it, but this is actually
0:26:03 > 0:26:06a bit of venison, which would make a big part of their diet in the wild.
0:26:06 > 0:26:10I've got to admit we're absolutely struggling here and Bill is just
0:26:10 > 0:26:12lying in the sunshine and going,
0:26:12 > 0:26:14"This is a doddle! I'm just chewing..."
0:26:14 > 0:26:16He's not even spending any energy.
0:26:16 > 0:26:18This is half of what he could do.
0:26:18 > 0:26:21But talk about these guys hunting out in the wild.
0:26:21 > 0:26:24Do they have any special adaptations to help them?
0:26:24 > 0:26:25Oh!
0:26:25 > 0:26:27He heard me!
0:26:29 > 0:26:32Basically, the lynx and their hunting, their main one
0:26:32 > 0:26:34is all about the stealth and the power.
0:26:34 > 0:26:37Hide, hide, and at last minute, go for their prey,
0:26:37 > 0:26:41and they use the great strength you're feeling now to overpower it.
0:26:41 > 0:26:44As well as being strong, are they really fast as well?
0:26:44 > 0:26:46They are for their size, but it is the strength.
0:26:46 > 0:26:48They have to be fast to catch deer
0:26:48 > 0:26:50or anything they'd be aiming to kill,
0:26:50 > 0:26:52but it's the strength that's the impressive bit.
0:26:52 > 0:26:56Once they've caught it, generally nothing gets out that grip.
0:26:56 > 0:26:59I'm impressed by his nails. I keep seeing those claws and thinking,
0:26:59 > 0:27:01"I just want to let go of the rope!"
0:27:01 > 0:27:05Johny, I think we should let go and say goodbye to you guys for now,
0:27:05 > 0:27:08and why don't you check out what's on the next episode of Roar?
0:27:10 > 0:27:11Next time on Roar:
0:27:11 > 0:27:13The baby tapir is out and about
0:27:13 > 0:27:17and we're going to find out how he's getting on.
0:27:17 > 0:27:19There's trouble with the cheetahs...
0:27:21 > 0:27:24..as the boys work out who's boss.
0:27:25 > 0:27:29And the Roar Ranger is facing his worst nightmare
0:27:29 > 0:27:32when he has to tackle one of the biggest pooers in the park.
0:27:32 > 0:27:34Ohh!
