0:00:02 > 0:00:04Today on Roar, you're in for a thriller
0:00:04 > 0:00:07when we go in search of the creatures of the night.
0:00:07 > 0:00:12But will we find them before they find us?
0:00:37 > 0:00:41- Hello, welcome to Roar. I'm Johny. - And I'm Rani. And these guys
0:00:41 > 0:00:43are the park's barasingha deer.
0:00:43 > 0:00:46Did you know the word "barasingha" is Hindi for "12 horns"
0:00:46 > 0:00:48referring to the 12 antler branches
0:00:48 > 0:00:50- coming out of their heads? - Impressive.
0:00:50 > 0:00:54Did you know their antlers can actually grow up to one metre long?
0:00:54 > 0:00:57Johny, that's like having your arms sticking out of my head.
0:00:57 > 0:01:00Imagine having an arm coming out of your head. Weird.
0:01:00 > 0:01:03What would you call these guys without any eyes?
0:01:03 > 0:01:07- No idea.- No-eye deer! Let's get on with today's show.
0:01:07 > 0:01:09Coming up on Roar...
0:01:09 > 0:01:13A very rare moloch gibbon is due to leave the park,
0:01:13 > 0:01:15but is she well enough to travel?
0:01:15 > 0:01:18Monty the python has taken a liking to Johny,
0:01:18 > 0:01:21but is he friendly...
0:01:21 > 0:01:22or hungry?
0:01:22 > 0:01:25And Jake the Roar Ranger is helping with the elephants,
0:01:25 > 0:01:28which could mean trouble for the film crew.
0:01:28 > 0:01:31LAUGHTER
0:01:34 > 0:01:39But first I'm rushing up to the moloch gibbon house,
0:01:39 > 0:01:42because Jane the vet is about to do a vital health check.
0:01:42 > 0:01:46Moloch gibbons are an endangered species.
0:01:46 > 0:01:50It's been estimated there's a 50/50 chance they'll become extinct
0:01:50 > 0:01:54in the next ten years.
0:01:54 > 0:01:58So it's important to try and breed them in captivity.
0:01:58 > 0:02:00To help, the park sometimes needs to send
0:02:00 > 0:02:05young adults away to start new families in other parks.
0:02:05 > 0:02:08Before an animal can be sent to another park,
0:02:08 > 0:02:10it has to be given a clean bill of health.
0:02:10 > 0:02:13I've come to the moloch gibbon enclosure
0:02:13 > 0:02:15- to catch up with Head of Primates, Matt. Hi, Matt.- Hello.
0:02:15 > 0:02:19- What's going on today?- Jane is currently sedating Simpang.
0:02:19 > 0:02:22- OK, Jane the vet.- Jane the vet.
0:02:22 > 0:02:24We need to wait out here until we've got the OK,
0:02:24 > 0:02:26then we'll go in and see what happens.
0:02:26 > 0:02:29It's quite a serious business to sedate an animal.
0:02:29 > 0:02:31- Is Simpang in any danger at the moment?- No.
0:02:31 > 0:02:34Simpang is completely healthy. This is all just routine.
0:02:34 > 0:02:38- So she's going to go and get a new home, is she?- Yeah, that's it.
0:02:38 > 0:02:41Do you think we can go in and see how Jane and Simpang are doing?
0:02:41 > 0:02:44- Yeah, I think it's fine. - Follow us inside
0:02:44 > 0:02:46and let's find out a little bit more.
0:02:46 > 0:02:51'Inside Simpang's bedroom, Jane has already given her a sedative drug
0:02:51 > 0:02:55'to send her to sleep, and checked her breathing and heartbeat.
0:02:55 > 0:02:58'But there's a lot more to do for the health check,
0:02:58 > 0:03:00'so she needs to work fast.'
0:03:00 > 0:03:04- Are you all right, Jane?- Yeah. - We'll let you do your job.
0:03:04 > 0:03:06How many tests do you have to do today?
0:03:06 > 0:03:09Basically, we just have to take some blood,
0:03:09 > 0:03:12but on that blood, we have to run eight or ten different tests.
0:03:12 > 0:03:15So quite a lot for her. But we don't need much blood,
0:03:15 > 0:03:19- so again, I don't think she'll notice.- Will you get results today
0:03:19 > 0:03:21- or do you send them off somewhere? - We send them off.
0:03:21 > 0:03:24It will take three weeks for them to come back
0:03:24 > 0:03:25so it's a slow, boring process.
0:03:25 > 0:03:31- Oh! Jane, they are some big teeth. - They're really big, aren't they?
0:03:31 > 0:03:35Is there a purpose for them? Does she eat meat?
0:03:35 > 0:03:38No, she doesn't eat meat. They're mainly for display,
0:03:38 > 0:03:43so to show the other gibbons, and it's a form of communication.
0:03:43 > 0:03:45They look pretty harsh.
0:03:45 > 0:03:49- Oh! Can we have a look at her feet? - Yeah.- This is such an honour.
0:03:49 > 0:03:51Harder than I thought they were going to be.
0:03:51 > 0:03:55- She's got nice little toenails. - She has! Oh, hello, beautiful.
0:03:55 > 0:03:59She is unbelievable. She's got these long nails.
0:03:59 > 0:04:02- No-one files these, do they?- No. - They're not too sharp.
0:04:02 > 0:04:06- She looks after them.- The toes are very bendy for gripping onto things.
0:04:06 > 0:04:08When I look at these, I always think about the gibbons,
0:04:08 > 0:04:11their fur looks so thick and fluffy, and it really is.
0:04:11 > 0:04:16- Little bit coarse.- It's not soft. - It's not soft, but it's very fluffy.
0:04:16 > 0:04:22- Then, little hand.- Really long fingers.- Yeah.- Are you artistic?
0:04:22 > 0:04:25That's what my mum says if you've got long fingers.
0:04:25 > 0:04:28Actually, really big hands. Can I turn your hand over?
0:04:28 > 0:04:32If I put her hand next to my hand, it's actually the same size.
0:04:32 > 0:04:34- It is. That's amazing. - That's shocking!
0:04:34 > 0:04:36Now we will wake up her up.
0:04:36 > 0:04:38How are you going to wake her up?
0:04:38 > 0:04:42We going to give her an injection that counteracts the sedatives.
0:04:42 > 0:04:46And probably in about ten minutes, she'll be awake again.
0:04:46 > 0:04:48So the MOT is now complete,
0:04:48 > 0:04:50and Simpang has been given the reversal drug,
0:04:50 > 0:04:52so join us later in the show
0:04:52 > 0:04:54when hopefully she won't be wobbling around.
0:05:05 > 0:05:08Today's Roar Ranger is Jake from Barnsley.
0:05:09 > 0:05:13At 11-years-old, he's already got a black belt in taekwondo.
0:05:13 > 0:05:16What does he want to do when he's older?
0:05:16 > 0:05:19In the future, I would like to work with animals or be a keeper.
0:05:19 > 0:05:22I think this will be brilliant training.
0:05:22 > 0:05:26And Jake has started his training at home.
0:05:26 > 0:05:28He helps look after the family pet, Maggie.
0:05:28 > 0:05:31Now let's see if that's going to help him today.
0:05:31 > 0:05:32"Jake..."
0:05:38 > 0:05:39Oh, cool.
0:05:39 > 0:05:41Let's get to it.
0:05:42 > 0:05:44How do I get out of here?
0:05:45 > 0:05:47Ah!
0:05:47 > 0:05:49TRUMPETS
0:05:49 > 0:05:51The park has 14 African elephants,
0:05:51 > 0:05:53making this the biggest herd in Britain.
0:05:53 > 0:05:56Looking after them all is a massive job.
0:06:00 > 0:06:03And today is also going to be a very wet one.
0:06:03 > 0:06:05It's started chucking it down.
0:06:07 > 0:06:11But elephants are waterproof and they still need looking after,
0:06:11 > 0:06:13so the work still needs to be done. For the keepers,
0:06:13 > 0:06:16rain never stops play.
0:06:16 > 0:06:19Hello, I'm Liz, nice to meet you. You must be Jake.
0:06:19 > 0:06:21- Yeah, I am.- You looking forward to today?- Yeah.
0:06:21 > 0:06:24- We've got a huge task ahead of us today.- What is it?
0:06:24 > 0:06:27What you're going to be doing is helping us feed the elephants.
0:06:27 > 0:06:31- How does that sound?- Sounds great! - Because they're so big,
0:06:31 > 0:06:34- they need lots of food so we've got lots of helpers.- I can imagine that.
0:06:34 > 0:06:37We're really pleased you've come to help us.
0:06:37 > 0:06:40- Shall we go?- Yep. - Lovely.- You're the boss.
0:06:40 > 0:06:45Before they get started on fetching the food,
0:06:45 > 0:06:47Jake's getting a look at the herd,
0:06:47 > 0:06:51and the rain has made them do something unusual.
0:06:51 > 0:06:53Can you see them in the pool, Jake?
0:06:53 > 0:06:56- Yeah.- It's really strange, they only really go in the pool
0:06:56 > 0:07:00- if it's really, really hot... - Or when it's raining.- Exactly.
0:07:00 > 0:07:02More so when it's raining. I don't know why.
0:07:02 > 0:07:06I suppose they think, "I'm wet enough, I might as well go swimming."
0:07:06 > 0:07:09Now they're more interested in getting breakfast,
0:07:09 > 0:07:13and here it is. 43 boxes of oranges, swedes,
0:07:13 > 0:07:16cabbages, apples and carrots.
0:07:16 > 0:07:19Elephants love their fruit and veg
0:07:19 > 0:07:22and they go through a lot more than just five a day.
0:07:22 > 0:07:24In fact, each of the adults
0:07:24 > 0:07:29chomps through six times Jake's weight in food every day.
0:07:30 > 0:07:33The last thing to load is the hay.
0:07:33 > 0:07:36Hey, Jake, why aren't you helping?
0:07:36 > 0:07:41I'm just watching. I don't want to have sticky, hairy fingers.
0:07:41 > 0:07:43Or hay fingers.
0:07:46 > 0:07:49He'll be getting "hay fingers" and worse before long,
0:07:49 > 0:07:53because next the food has got to be served, and that can be a mucky job
0:07:53 > 0:07:55when it's raining like this,
0:07:55 > 0:07:58especially if you're standing near Jake.
0:07:58 > 0:08:00LAUGHTER
0:08:00 > 0:08:03We'll be back out in the rain later on.
0:08:03 > 0:08:04- ALL LAUGH - On the camera!
0:08:04 > 0:08:05Whoops!
0:08:08 > 0:08:10- What do you get if you sit under a cow?- I don't know.
0:08:10 > 0:08:13A pat on the head. BOTH: Moo!
0:08:13 > 0:08:15BOTH: Woof, woof!
0:08:15 > 0:08:17BOTH PANT Woof, woof!
0:08:17 > 0:08:20- What's grey and goes round and round?- I don't know.
0:08:20 > 0:08:22An elephant in a washing machine.
0:08:22 > 0:08:24BOTH GIGGLE
0:08:24 > 0:08:25SHE QUACKS
0:08:25 > 0:08:28- What bone will a dog never eat? - I don't know.
0:08:28 > 0:08:32- A trombone. - BOTH LAUGH
0:08:32 > 0:08:33ALL LAUGH
0:08:40 > 0:08:43Back at the moloch gibbon enclosure, an hour has gone by
0:08:43 > 0:08:46since the vet finished doing a medical health check
0:08:46 > 0:08:47on the female named Simpang.
0:08:47 > 0:08:50She should have woken up from the sedative by now,
0:08:50 > 0:08:54so keeper Matt and I are waiting to see how she is.
0:08:54 > 0:08:58Oh, here she comes and there's those long arms,
0:08:58 > 0:09:01and those long fingers that I got so close to before.
0:09:01 > 0:09:03She seems steady, so the anaesthetic's worn off.
0:09:03 > 0:09:05That's excellent.
0:09:05 > 0:09:07Oh! Let's see, can she swing?
0:09:07 > 0:09:08A little bit slow,
0:09:08 > 0:09:12- cos these guys are fantastic at swinging, aren't they?- Yeah.
0:09:12 > 0:09:13Hi, darling!
0:09:13 > 0:09:15Should I step away a little bit?
0:09:15 > 0:09:16Just a little bit.
0:09:16 > 0:09:20She hasn't had her morning feed, so she's more hungry than anything.
0:09:20 > 0:09:22And look at that...
0:09:22 > 0:09:25She's gone for something nice and sweet.
0:09:25 > 0:09:28She looks perfectly fine which is brilliant news.
0:09:28 > 0:09:30Yeah, definitely.
0:09:30 > 0:09:33Now, you did a few tests, it's because you're sending her away!
0:09:33 > 0:09:34Yeah, unfortunately.
0:09:34 > 0:09:35Why would you do that?
0:09:35 > 0:09:38It's very important that they breed.
0:09:38 > 0:09:42Moloch gibbons, in the wild, are very few, there's not many at all.
0:09:42 > 0:09:46And in captivity, there's even fewer, there's only 40 in captivity.
0:09:46 > 0:09:48There's only 40!
0:09:48 > 0:09:51- And you've got quite a few here, though.- We've 19 at the moment,
0:09:51 > 0:09:54so we've kind of got half of the captive population.
0:09:54 > 0:09:56And, in the wild, where are they from?
0:09:56 > 0:09:57Java.
0:09:57 > 0:09:58And how many are left out there?
0:09:58 > 0:10:02It's between 2,000 and 3,000, so there's not particularly many at all.
0:10:02 > 0:10:03Hardly any, then.
0:10:03 > 0:10:06So, it's vital for us to breed them.
0:10:06 > 0:10:10We're at capacity now, so we need to find somewhere else to breed them,
0:10:10 > 0:10:12and this is what's going to happen in America.
0:10:12 > 0:10:14High five me on that one.
0:10:14 > 0:10:16That is very, very good news.
0:10:16 > 0:10:19Well, Matt, that's great about the breeding programme,
0:10:19 > 0:10:21and to see Simpang up and about,
0:10:21 > 0:10:25stretching those long arms and enjoying a guava...
0:10:25 > 0:10:27Today has been a success.
0:10:34 > 0:10:38Back up in the elephant field, our Roar Ranger has a problem.
0:10:38 > 0:10:43The thing is, to people like Liz, getting mucky is a way of life.
0:10:43 > 0:10:45But Jake hasn't quite got used to it yet.
0:10:45 > 0:10:48So, why don't you want to put it out?
0:10:48 > 0:10:50Cos I don't want to get my fingers all messy.
0:10:50 > 0:10:53Oh! I'm sure the rain will wash it off.
0:10:53 > 0:10:56JAKE LAUGHS
0:10:56 > 0:10:59- Oh! Thank you very much! - That's all right, you're welcome!
0:10:59 > 0:11:01You're lucky it's not poo.
0:11:01 > 0:11:02This is clean stuff,
0:11:02 > 0:11:06you could be on the cats getting all blood and guts on you.
0:11:06 > 0:11:09Then Jake decides to have a go...
0:11:09 > 0:11:12- Oh, might as well. - JAKE LAUGHS
0:11:12 > 0:11:14Oh, there's a class bit.
0:11:14 > 0:11:16Lovely, thank you very much.
0:11:16 > 0:11:20..and discovers that soggy, messy hay isn't so bad...
0:11:23 > 0:11:25..and can be fun.
0:11:25 > 0:11:30But the fun's just starting, because now it's time to fling the food out.
0:11:30 > 0:11:33Just try not to hit anybody else in the process.
0:11:35 > 0:11:36Donk!
0:11:36 > 0:11:37Right, so get a shovel load...
0:11:42 > 0:11:45Watch out, Jake, carrots can be dangerous!
0:11:46 > 0:11:51This dumper-truck full is just one of the elephants' daily feeds.
0:11:51 > 0:11:54Later, they'll get a supper of more hay plus browse.
0:11:54 > 0:11:55Done!
0:11:55 > 0:11:57Want to chuck your shovel on there?
0:11:57 > 0:11:58Yeah.
0:11:58 > 0:11:59Chuck it on.
0:11:59 > 0:12:02And it's still raining.
0:12:02 > 0:12:04Now to let the elephants out,
0:12:04 > 0:12:07and Jake's ready to tackle the next keeper skill -
0:12:07 > 0:12:09giving orders on the walkie-talkie.
0:12:09 > 0:12:12Coming through, now.
0:12:12 > 0:12:16The first out to breakfast is the bull elephant, Jums.
0:12:16 > 0:12:20He's the biggest in the herd at five and a half tonnes,
0:12:20 > 0:12:22that's the weight of about five cars.
0:12:23 > 0:12:25- Ooh! - JAKE LAUGHS
0:12:25 > 0:12:28It'll take the herd less than an hour
0:12:28 > 0:12:30to scoff all that food they put out.
0:12:30 > 0:12:33I think you've done very well today as a Roar Ranger.
0:12:33 > 0:12:36Bit funny about hay, weren't you? At first, but...
0:12:36 > 0:12:39You got dirty in the end, that's the main thing.
0:12:39 > 0:12:41No, you've been very helpful, thank you.
0:12:41 > 0:12:43Shall we go and get dried off?
0:12:43 > 0:12:45Yeah, definitely.
0:12:45 > 0:12:47Brr!
0:12:47 > 0:12:51Today, Jake has experienced two sides of being a keeper -
0:12:51 > 0:12:52the good and the bad.
0:12:52 > 0:12:57I found being the elephant keeper a really cold job.
0:12:57 > 0:12:58And when it's in rain,
0:12:58 > 0:13:01it's a bit messy with all that hay sticking to you.
0:13:03 > 0:13:05It isn't a very nice day,
0:13:05 > 0:13:09but...zookeepers have to go, rain or shine.
0:13:11 > 0:13:13I still want to be a keeper...
0:13:13 > 0:13:16in the sun, where it's a bit warmer.
0:13:17 > 0:13:19Don't really know about rain yet.
0:13:19 > 0:13:24Um, there will be a nice warm cup of tea in the house,
0:13:24 > 0:13:26so I'll be warm in no time.
0:13:33 > 0:13:37Being a real-life keeper can be wet and cold.
0:13:37 > 0:13:41But don't forget, you can look after a whole range of virtual animals
0:13:41 > 0:13:43from the comfort of your own home.
0:13:43 > 0:13:47Just go to the Roar game on the CBBC website.
0:13:47 > 0:13:50Today's cheat code is "grass3".
0:13:50 > 0:13:52Make a note of that now, you'll need it later
0:13:52 > 0:13:57to get food, treats or extra features. Happy gaming.
0:14:02 > 0:14:07In the wild, there are many animals that spend all day just snoozing,
0:14:07 > 0:14:09because they're active at night.
0:14:09 > 0:14:13Lions, for example, often make their kills after dark.
0:14:13 > 0:14:18Others, like the red panda, are naturally more active
0:14:18 > 0:14:20at dawn and twilight.
0:14:20 > 0:14:24So, what goes on at the park after it closes for the evening?
0:14:24 > 0:14:28The person to ask is Jim Vassey. He's the head of the big cats,
0:14:28 > 0:14:31and the last to leave every night.
0:14:31 > 0:14:37It's his job to make sure the place is safely closed down.
0:14:37 > 0:14:40Yeah, I'm just locking up, waiting for the last customers to go.
0:14:40 > 0:14:42In fact, here they come now.
0:14:43 > 0:14:45Cheers, all the best.
0:14:48 > 0:14:51Almost done. Just a few more little things to do.
0:14:51 > 0:14:55I do a drive-by, make sure the zoo's empty.
0:14:55 > 0:14:59I also like to go and see a few animals you wouldn't normally see.
0:14:59 > 0:15:03This evening, we're coming out with Jim on his rounds.
0:15:03 > 0:15:07It's a great chance to find out what the animals do when no-one's there.
0:15:10 > 0:15:13But first, Jim needs to check up on a cat
0:15:13 > 0:15:15who's recovering from an operation -
0:15:15 > 0:15:18Scabby, the Indian tiger.
0:15:18 > 0:15:21This is the best time to see tigers.
0:15:21 > 0:15:25Especially Scabs, here, because of her age.
0:15:25 > 0:15:29And the heat, she spends a lot of time in the shade or in her shed.
0:15:29 > 0:15:33This is always a good opportunity because there's no-one here
0:15:33 > 0:15:34and it's nice and quiet.
0:15:37 > 0:15:39Hiya, sweetheart. How are you?
0:15:39 > 0:15:43At 20 years of age, Scabby is very old for a tiger.
0:15:43 > 0:15:46Her general health is quite good
0:15:46 > 0:15:48but Jim needs to keep a close eye on her,
0:15:48 > 0:15:50especially this evening.
0:15:50 > 0:15:53One of the reasons I've come up tonight,
0:15:53 > 0:15:57though I come up quite often, is she had a minor operation this morning.
0:15:57 > 0:16:04She had an ingrowing claw, which we've had removed by the vet.
0:16:04 > 0:16:07And I basically just wanted to check on her. She's still limping,
0:16:07 > 0:16:10but here she comes. Hiya, sweetheart.
0:16:10 > 0:16:12How's your paw?
0:16:12 > 0:16:15You're not happy with us, are you? Eh?
0:16:15 > 0:16:19I can see from here, her paw is still quite swollen.
0:16:19 > 0:16:23But all things considered, her age, it looks pretty good.
0:16:23 > 0:16:26But, with big cats, it's one of these things.
0:16:26 > 0:16:28As they get older, they get lazier.
0:16:28 > 0:16:31They don't keep their claws sharp enough or short enough.
0:16:31 > 0:16:34Hence you get ingrowing claws.
0:16:34 > 0:16:37But she's none the worse for it.
0:16:37 > 0:16:40You're a good girl.
0:16:40 > 0:16:44Checking up on animals that have had problems, like Scabby,
0:16:44 > 0:16:48is just one of the things Jim has to do on his twilight rounds.
0:16:49 > 0:16:52The place is just mine tonight.
0:16:52 > 0:16:55I always drive through the park anyway, to check on stuff.
0:16:55 > 0:16:59But you always get the urge to stop and say "hello" to something.
0:16:59 > 0:17:04Which is what I'll be doing later. A sneaky peeky at someone else!
0:17:07 > 0:17:09The sun's going down but Jim still needs to check
0:17:09 > 0:17:12on a creature that kills in the dark,
0:17:12 > 0:17:15and pay a visit to the spirits of the night. So, don't go away
0:17:15 > 0:17:18cos things are getting spooky around here!
0:17:20 > 0:17:24SPOOKY LAUGHTER
0:17:36 > 0:17:38Now, there are many things the keepers do
0:17:38 > 0:17:41to keep their animals occupied throughout the day.
0:17:41 > 0:17:44But when I heard that the rhino section were going bowling
0:17:44 > 0:17:47with their rhinos, I thought, "This is taking it too far."
0:17:47 > 0:17:49How are the rhinos going to be able
0:17:49 > 0:17:51to get their bowling shoes on in the first place?
0:17:51 > 0:17:54So we've got a rhino here, I see the bowling balls
0:17:54 > 0:17:56and I see keeper, Shelley Kettle.
0:17:56 > 0:17:58Shelley, tell me this isn't true.
0:17:58 > 0:18:00I'm afraid it is, yes.
0:18:00 > 0:18:03One of our weird ways of enriching our rhinos.
0:18:03 > 0:18:05We thought we'd give bowling balls a try.
0:18:05 > 0:18:08We've heard about other places doing it and thought,
0:18:08 > 0:18:10"Let's see what Arusha makes of them."
0:18:10 > 0:18:13You're not actually going bowling with the rhinos?
0:18:13 > 0:18:15No, we're not!
0:18:15 > 0:18:16- Thank you!- Definitely not.
0:18:16 > 0:18:20We're just going to stuff little bits of fruit into the holes
0:18:20 > 0:18:23and smear them with banana as well, make it all smell nice.
0:18:23 > 0:18:27And put it in the paddock for her and see what she makes of it.
0:18:27 > 0:18:30Hopefully she'll knock it around and get a few treats out of it.
0:18:30 > 0:18:33Just give her a bit of enrichment, really.
0:18:33 > 0:18:35How do I go about feeding a rhino by hand?
0:18:35 > 0:18:37- Basically, let them sniff it.- Yeah.
0:18:37 > 0:18:39They decide if they want it and open wide.
0:18:39 > 0:18:40- Wow.- And they pull it in.
0:18:40 > 0:18:43Has she got big teeth in there, that I have to worry about?
0:18:43 > 0:18:46They have, but they're set really far back.
0:18:46 > 0:18:48So she can't bite you very easily.
0:18:48 > 0:18:52- So you can put your hand right in there.- Squash!
0:18:54 > 0:18:56But don't try this yourself, kids.
0:18:56 > 0:18:59I can only feed this rhino because I'm with a trained keeper.
0:18:59 > 0:19:02Otherwise it would be dangerous to even get this close.
0:19:02 > 0:19:04She's definitely intrigued. Look at this.
0:19:04 > 0:19:07- Shall we get one on the go?- Yeah. - Go on, then.
0:19:07 > 0:19:10- What have we got? - Some raspberry, there.
0:19:10 > 0:19:13- And is this grape?- Yeah.
0:19:13 > 0:19:16Does she usually have things like this?
0:19:16 > 0:19:20It's not anything she usually gets, which hopefully will be nice for her,
0:19:20 > 0:19:23make a change. And raspberries smell quite strong as well.
0:19:23 > 0:19:25That's it, good girl.
0:19:25 > 0:19:26Right, so she's liking the banana.
0:19:26 > 0:19:30- She is.- Right, let's smear this all over the ball, then.
0:19:30 > 0:19:31How will she know it's there?
0:19:31 > 0:19:34Do you think it's a smell thing or a sight thing?
0:19:34 > 0:19:37It'll be quite close to her, so she will be able to see the ball.
0:19:37 > 0:19:40But also, it's the smell that she's going to pick up,
0:19:40 > 0:19:42that there's food on that ball.
0:19:42 > 0:19:45I think you want the rest of my mushy banana! Go on, then.
0:19:45 > 0:19:47Let's give her the banana so she's got a taste for it.
0:19:47 > 0:19:50- What do you reckon, shall we put the ball in now?- Yeah.
0:19:50 > 0:19:53- Shall we bowl it in?- You can go first cos you're the expert.
0:19:53 > 0:19:56I'm going to get really sticky fingers in these holes.
0:19:56 > 0:19:59There's a flaw in the plan! I can't fit in the holes anymore.
0:20:01 > 0:20:03Come on, what's this, darling?
0:20:03 > 0:20:07So, are you going to put it far away or just leave it nearby?
0:20:07 > 0:20:10- I'll just leave it nearby, roll it in and see what happens, shall we?- OK.
0:20:10 > 0:20:14She can smell the banana on my hands, so hopefully she'll go...
0:20:14 > 0:20:15Oh, she's seen it.
0:20:15 > 0:20:17- What is it, Arusha-roo?- Wow.
0:20:17 > 0:20:20- What is it?- Look at that.
0:20:20 > 0:20:21Oh, banana!
0:20:21 > 0:20:25Shelley, out of all the things that you could use for a toy,
0:20:25 > 0:20:27why a bowling ball?
0:20:27 > 0:20:29Basically, cos they're very strong.
0:20:29 > 0:20:32Rhinos are quite capable of breaking most things
0:20:32 > 0:20:34and bowling balls are very hard and durable.
0:20:34 > 0:20:37The idea is that she can play with it without breaking it.
0:20:38 > 0:20:41Well, this has been an interesting experiment.
0:20:41 > 0:20:44And although Arusha can't break the bowling ball,
0:20:44 > 0:20:46she's not too sure what to do with it either.
0:20:46 > 0:20:49Lick it or kick it!
0:20:53 > 0:20:57As daylight fades, everything changes.
0:20:57 > 0:21:01Now the nocturnal animals, who are active at night,
0:21:01 > 0:21:04begin to stir. And Jim Vassey needs to check on them.
0:21:08 > 0:21:11Now that the sun's gone down, the park takes on a new meaning.
0:21:11 > 0:21:16Now, animals that are nocturnal will start to come to life.
0:21:16 > 0:21:19We're now inside the enclosure of a creature whose name,
0:21:19 > 0:21:22where they come from, means "spirit of the night".
0:21:22 > 0:21:24They can be seen during the day
0:21:24 > 0:21:27but they really get active after dusk.
0:21:31 > 0:21:33Can't see a thing at the moment.
0:21:33 > 0:21:36But I can assure you, they're in here somewhere.
0:21:36 > 0:21:39There are seven of them out there in the darkness.
0:21:39 > 0:21:40While we can't see them,
0:21:40 > 0:21:44they're certainly watching every move Jim makes.
0:21:44 > 0:21:47At this time of night, they're not used to people.
0:21:47 > 0:21:51That's why I've brought some strawberries, to make friends.
0:21:51 > 0:21:55And if you want to make friends with a black and white ruffed lemur,
0:21:55 > 0:21:58strawberries are powerful magic.
0:21:59 > 0:22:02In fact, these animals are crepuscular,
0:22:02 > 0:22:07which means they are most active at dawn and dusk.
0:22:07 > 0:22:10I'll give you one more, you've had plenty. Let's find someone else.
0:22:10 > 0:22:13Lemurs are a type of primate and, like monkeys,
0:22:13 > 0:22:16they've evolved to live mainly in the tree tops.
0:22:16 > 0:22:21They've got long limbs and toes that grip like hands.
0:22:21 > 0:22:23Take your time.
0:22:25 > 0:22:26That's it.
0:22:26 > 0:22:31You see? Look at the posture of that. Amazing.
0:22:31 > 0:22:33They do this all the time in the wild, but...
0:22:33 > 0:22:36Oh! Unfortunately, somebody wanted all of them.
0:22:38 > 0:22:40It's amazing that they can just...
0:22:41 > 0:22:44Oh, help yourself!
0:22:44 > 0:22:46HE LAUGHS
0:22:46 > 0:22:49I think that's the last I'm going to see of them... Oh!
0:22:49 > 0:22:53That's it, kids. Sorry, all the strawberries are gone.
0:22:53 > 0:22:55Although the lemurs are crepuscular,
0:22:55 > 0:22:57they are also seen in daytime.
0:22:57 > 0:23:01But there are animals here that rarely come out until night.
0:23:01 > 0:23:04And now Jim needs to check on them.
0:23:08 > 0:23:11I just want to pop up to see these clouded leopards.
0:23:11 > 0:23:14These are always active at night.
0:23:15 > 0:23:17Hello, Ben.
0:23:17 > 0:23:21Beautiful cat. They are true nocturnal cats.
0:23:21 > 0:23:26And you quite often find food the next day that we didn't give them.
0:23:26 > 0:23:28So they do hunt their own food.
0:23:28 > 0:23:31Birds and things like that get in there.
0:23:31 > 0:23:33Once they're in there, they're fair game.
0:23:33 > 0:23:36This time of night, you wouldn't risk going in there,
0:23:36 > 0:23:39because, one, they can see ten times better than us.
0:23:39 > 0:23:41They're much quicker, but very dangerous.
0:23:41 > 0:23:45Clouded leopards have fantastic night vision and live in the trees.
0:23:45 > 0:23:48They hunt in the dark and drop silently for the kill.
0:23:48 > 0:23:52The prey never knows a thing until it's all over.
0:23:53 > 0:23:56There's a kitten up there, look.
0:23:56 > 0:23:58Hi, sweetheart. Hello.
0:24:01 > 0:24:05Mum's in there, look. Hiding in the undergrowth, there.
0:24:05 > 0:24:07Excellent parents.
0:24:07 > 0:24:10Waah-waah.
0:24:10 > 0:24:13Yeah, I won't invade their territory tonight.
0:24:13 > 0:24:15But it's nice to see them out and about.
0:24:17 > 0:24:19But some of the night-time killers
0:24:19 > 0:24:22are more likely to be heard than seen.
0:24:24 > 0:24:26Can you hear the wolves in the background?
0:24:26 > 0:24:30WOLVES HOWL
0:24:30 > 0:24:35I can hear an aeroplane but they're howling above the aeroplane.
0:24:37 > 0:24:39LOUD HOWLING
0:24:39 > 0:24:41That's great.
0:24:43 > 0:24:45It's eerie, listening to it in the dark.
0:24:45 > 0:24:47But it's still a very good...
0:24:47 > 0:24:52Good sign that they're happy, that's the male and the female calling.
0:24:52 > 0:24:55There, that was the male, the second one.
0:25:02 > 0:25:07And there's one last thing I want to do, as I'm by myself.
0:25:07 > 0:25:10Hang on, that's the elephant keeper's shed.
0:25:10 > 0:25:13Surely there's nothing nocturnal in there?
0:25:14 > 0:25:16What is he up to?
0:25:16 > 0:25:18Ah-ha-ha!
0:25:22 > 0:25:25My favourite. And Dave's - Jaffa Cakes.
0:25:25 > 0:25:28Sorry, Dave, they're mine!
0:25:29 > 0:25:33And that shows precisely why some animals are nocturnal -
0:25:33 > 0:25:35when the daytime creatures are in bed,
0:25:35 > 0:25:39the night dwellers can get away with all sorts of mischief.
0:25:39 > 0:25:43SPOOKY LAUGHING
0:26:00 > 0:26:02Now, we were about to leave you today,
0:26:02 > 0:26:05but then we heard there was a new arrival at the Discovery Zone.
0:26:05 > 0:26:08So we popped up to check out head keeper Rich and his new necklace!
0:26:08 > 0:26:11Rich, who is this?
0:26:11 > 0:26:14This is one of our latest arrivals, this is a carpet python.
0:26:14 > 0:26:18And no, we didn't name him this, but he's called Monty Python.
0:26:18 > 0:26:20- Wa-hey!- I like it!
0:26:20 > 0:26:25Now, he's got himself wrapped around my wrist here. Are we safe?
0:26:25 > 0:26:29Yeah, we're pretty safe. He's pretty harmless to us at this size.
0:26:29 > 0:26:31He's quite strong but he's not a threat to us in any way.
0:26:31 > 0:26:35He's anchoring himself there, he thinks you're a branch.
0:26:35 > 0:26:38He's quite chatty, isn't he? Shh, we're on telly!
0:26:38 > 0:26:42He's very beautiful, Rich, but before he gets too friendly with me,
0:26:42 > 0:26:45I think we should get out of here. What do you reckon, Rani?
0:26:45 > 0:26:47I think that's a good plan!
0:26:47 > 0:26:51OK, whilst Johny releases himself from Monty the carpet python,
0:26:51 > 0:26:54check out what's on the next episode of Roar. I think he likes you!
0:26:54 > 0:26:57I think he does.
0:26:57 > 0:26:58Next time...
0:26:58 > 0:27:01Yoda the red panda is injured
0:27:01 > 0:27:04and must be rushed to the vet for an emergency operation.
0:27:04 > 0:27:06But will he survive?
0:27:06 > 0:27:10Gorillas are one of our closest relatives in the animal world.
0:27:10 > 0:27:12But do we share the same tastes?
0:27:12 > 0:27:14That is really hard.
0:27:14 > 0:27:17And there are highs...
0:27:17 > 0:27:19and lows...
0:27:19 > 0:27:24when the gang try to discover why the ocelots pong a lot.
0:27:24 > 0:27:25So don't miss it.
