0:00:02 > 0:00:06On Roar today - there's a baby rhino like this on the way,
0:00:06 > 0:00:10but the dad is being aggressive to the mum.
0:00:10 > 0:00:13If they were sparring and it got out of control,
0:00:13 > 0:00:15it could do a lot of damage.
0:00:15 > 0:00:18Will the keepers be able to separate them?
0:00:43 > 0:00:47- Hello and welcome to Roar. I'm Johny.- And I'm Rani.
0:00:47 > 0:00:49Johny, I have a challenge for you.
0:00:49 > 0:00:54In under 20 seconds, give me three facts about these Grant's zebras.
0:00:54 > 0:00:57- OK, Johny, your time starts now.- OK.
0:00:57 > 0:00:58They come from East Africa,
0:00:58 > 0:01:02out in the wild they're known to migrate in herds of up to 10,000,
0:01:02 > 0:01:07- and out of all species of zebra... - 10 seconds!- ..they're smallest. Yes!
0:01:07 > 0:01:09I've done it. What do I win?
0:01:09 > 0:01:13Um...oh! You win this magical wand.
0:01:13 > 0:01:15Rani, that's a stick.
0:01:15 > 0:01:18Rubbish. Let's get on with the rest of the show.
0:01:19 > 0:01:23Coming up - a beautiful baby tapir has a nasty infection,
0:01:23 > 0:01:26and the keepers are worried that he might die of it,
0:01:26 > 0:01:28just like his brother did.
0:01:28 > 0:01:32Our Roar ranger hits the heights of the gorilla house,
0:01:32 > 0:01:35but there are bigger dangers than falling off.
0:01:35 > 0:01:39Keep walking along. That noise she's making means she's getting annoyed,
0:01:39 > 0:01:41so we should stay out of her way.
0:01:41 > 0:01:45And what on earth is going on in the Diana monkey enclosure?
0:01:45 > 0:01:49Are they having a disco down there?
0:01:52 > 0:01:55But first, we're off to the hoof stock section
0:01:55 > 0:01:58to catch up with one of the park's cutest babies -
0:01:58 > 0:02:00a Brazilian tapir.
0:02:00 > 0:02:04Not long ago, our cameras captured these amazing shots
0:02:04 > 0:02:07just after Wilma gave birth to him,
0:02:07 > 0:02:11and we saw the little boy taking his first steps.
0:02:11 > 0:02:12That was a month ago
0:02:12 > 0:02:16and the little baby boy has got a lot bigger.
0:02:16 > 0:02:19But he has also got diarrhoea.
0:02:19 > 0:02:21That can just mean a runny tummy
0:02:21 > 0:02:23but it can also be a killer disease,
0:02:23 > 0:02:28and head of section Joel Bunce has good reason to be worried.
0:02:28 > 0:02:31Wilma had a calf - her last calf was 11 years ago -
0:02:31 > 0:02:34and unfortunately, it didn't form properly inside.
0:02:34 > 0:02:36It appeared healthy when it was born
0:02:36 > 0:02:40and for the first few weeks, it was great while it was suckling
0:02:40 > 0:02:44but when it started to adapt to solid food, it couldn't digest it
0:02:44 > 0:02:49and the food was staying in the stomach and, basically, going off,
0:02:49 > 0:02:52so the calf was getting diarrhoea
0:02:52 > 0:02:54and it lost a lot of weight and condition,
0:02:54 > 0:02:58and unfortunately passed away.
0:02:58 > 0:03:01So Joel's taking no chances with this calf
0:03:01 > 0:03:04and, luckily, the medicine he's got from the vet
0:03:04 > 0:03:06appears to be working.
0:03:06 > 0:03:11At the moment, we're giving him a syringe of probiotic powder
0:03:11 > 0:03:15mixed with water, and we syringe that straight into his mouth.
0:03:15 > 0:03:17There we go.
0:03:17 > 0:03:22That basically helps his gut bacteria adjust to all the things
0:03:22 > 0:03:26that they'll pick up naturally in the wild and in captivity,
0:03:26 > 0:03:31and also while his stomach's trying to adjust from milk to solids.
0:03:31 > 0:03:35Although he's very dependent, still, on Mum's milk,
0:03:35 > 0:03:39he is starting to eat a few solid bits now,
0:03:39 > 0:03:43so we have to balance that and make sure that he gets enough of each.
0:03:43 > 0:03:44His diarrhoea has slowed down.
0:03:44 > 0:03:49Although it's still watery, he's not producing as much, which is good.
0:03:49 > 0:03:52So, hopefully, we're winning on that front.
0:03:52 > 0:03:55Once it slows down and the probiotic starts working,
0:03:55 > 0:03:59it should start to form up and he should be a lot better.
0:03:59 > 0:04:01But because the earlier calf died,
0:04:01 > 0:04:05Joel's had the diarrhoea checked by an expert anyway.
0:04:05 > 0:04:08We've taken a sample that the vets will check under a microscope
0:04:08 > 0:04:13to see that there's nothing horrible that may cause a bigger problem.
0:04:15 > 0:04:17We can only hope there isn't.
0:04:17 > 0:04:21Joel will be keeping a close eye on him
0:04:21 > 0:04:24and will let us know when he gets the results from the tests.
0:04:35 > 0:04:39It's disco time down here at the Diana monkey enclosure.
0:04:39 > 0:04:43Joining me is the man with all the moves - keeper Jamie Robertson.
0:04:43 > 0:04:46How you doing, Jamie? You've got your disco ball -
0:04:46 > 0:04:50give me your best move, then. Come on. Oh! I'm loving it.
0:04:50 > 0:04:54So why have we got this here in the middle of the park?
0:04:54 > 0:04:57The idea is that it's a visual enrichment.
0:04:57 > 0:05:00A lot of the enrichment we use is food based,
0:05:00 > 0:05:03so they get a reward of food for doing something,
0:05:03 > 0:05:07whereas this is visual, so they can almost make out their reflection,
0:05:07 > 0:05:11there's points of light that, as the wind moves, the ball moves,
0:05:11 > 0:05:15so they can follow them. It's also in the cage. So lots of things to do.
0:05:15 > 0:05:18How come we've put it out here and not in the enclosure?
0:05:18 > 0:05:21Although this is fairly durable,
0:05:21 > 0:05:23I'm not sure it'd stand up to them trashing it.
0:05:23 > 0:05:26They could pick off the mirrors, which isn't a good thing.
0:05:26 > 0:05:30Do you think it'd freak them out, seeing their own reflection?
0:05:30 > 0:05:34It depends. Most monkeys, if they see a large mirror,
0:05:34 > 0:05:38they seem to think that it is another monkey and do get stressed,
0:05:38 > 0:05:44but if it's lots of small mirrors, they can't make out their reflection,
0:05:44 > 0:05:46so they don't get stressed by it.
0:05:46 > 0:05:50- Right, James, shall we give it a bit of a spin?- Go for it.- OK.
0:05:50 > 0:05:51Disco on!
0:05:51 > 0:05:55- Right... Oh, who is this, here? - That's Icarus.
0:05:57 > 0:06:00Do you think it's a bit scary for them to see the light?
0:06:00 > 0:06:05It's something unknown, so they have to make sure they like it.
0:06:07 > 0:06:10Ha-ha! They're going for it now.
0:06:11 > 0:06:14See the little dance move there? Back flip.
0:06:14 > 0:06:16I like it. They seem fascinated by it.
0:06:16 > 0:06:19What do you think's going through their heads?
0:06:19 > 0:06:23Don't know. It's completely unknown so it's completely
0:06:23 > 0:06:24"What is that?"
0:06:24 > 0:06:28They may see their reflection in their water bowl
0:06:28 > 0:06:32- but that's as close as they've got to this.- Have they got good eyesight?
0:06:32 > 0:06:35Exceptional. They constantly need to look out for predators,
0:06:35 > 0:06:37search for food,
0:06:37 > 0:06:40so eyesight is one of their most important senses.
0:06:40 > 0:06:44Would you say they're naturally curious or because of the predators,
0:06:44 > 0:06:47they're a bit standoffish when they see things like this -
0:06:47 > 0:06:48they're not sure about it?
0:06:48 > 0:06:52they are very curious - that's why I thought I'd try this with them -
0:06:52 > 0:06:56they're constantly investigating. You put new toys or rotten logs in,
0:06:56 > 0:06:59they're looking through the logs, checking out the toys.
0:06:59 > 0:07:02They've very curious to see if there's food there
0:07:02 > 0:07:03or just play with it.
0:07:03 > 0:07:07It seems to have gone down well with them. No dance moves yet, though.
0:07:07 > 0:07:10- Shall we make up for that? - Go for it - I'll follow your lead.
0:07:10 > 0:07:14Oh, yeah! Oh, yeah!
0:07:31 > 0:07:32Rahh!
0:07:32 > 0:07:36Today's Roar ranger is nine-year-old Lucy from Essex.
0:07:36 > 0:07:37Oo-oo-oo!
0:07:37 > 0:07:38This budding gymnast
0:07:38 > 0:07:41is used to looking after her pet hamster, Gingernut.
0:07:41 > 0:07:45But is she up for the hard work of being a Roar ranger?
0:07:45 > 0:07:50I'm up for it, all right. I don't care if I have to clean out poo.
0:07:51 > 0:07:57But being a Roar ranger doesn't always mean cleaning up poo.
0:07:57 > 0:08:00Well, now I think about it, it usually does!
0:08:00 > 0:08:04Let's find out which animal Lucy'll be looking after.
0:08:07 > 0:08:11Oh, yay! Yay! Yay! I really love the gorillas.
0:08:11 > 0:08:14They're one of the best animals in the world!
0:08:16 > 0:08:20Lucy will be helping to look after the park's Western Lowland gorillas.
0:08:20 > 0:08:24Originally from West Africa, they live in family groups - troops.
0:08:24 > 0:08:30Sadly, they are critically endangered in the wild
0:08:30 > 0:08:32but the park has the largest number
0:08:32 > 0:08:34of captive gorillas in Europe - over 50.
0:08:34 > 0:08:39So deputy head keeper Brian could do with a hand.
0:08:39 > 0:08:40Hi, Lucy, I'm Brian.
0:08:40 > 0:08:42Have you figured out what you're doing today?
0:08:42 > 0:08:44I think I've got an idea.
0:08:44 > 0:08:47You're going to pick up all their poo with your hands.
0:08:47 > 0:08:51Not really. You're going to give them some food off the roof.
0:08:51 > 0:08:52That sounds really fun.
0:08:54 > 0:08:56The gorillas are vegetarians
0:08:56 > 0:08:59and munch their way through 30 different types of fruit
0:08:59 > 0:09:02and 20 kinds of vegetables every week.
0:09:05 > 0:09:09We're going to feed the gorillas some grapes. And maybe a bit of lettuce.
0:09:09 > 0:09:13But the grapes have to be prepared for these gourmet gorillas.
0:09:15 > 0:09:17OK, Lucy, what we need to do with these,
0:09:17 > 0:09:19just break them up into smaller bundles
0:09:19 > 0:09:22so some greedy gorilla doesn't eat them all in one go.
0:09:22 > 0:09:26While we're doing that, if you see any bad ones, throw them in the bin.
0:09:30 > 0:09:34- I can't break that one. That's really hard.- You're sacked.
0:09:34 > 0:09:36Brian's only joking.
0:09:36 > 0:09:38Ooh, that's definitely a bad one.
0:09:38 > 0:09:40Eurgh!
0:09:41 > 0:09:43Grape juice!
0:09:50 > 0:09:52The snacks will be served on the roof,
0:09:52 > 0:09:55but it's quite safe. The keepers come up all the time.
0:09:55 > 0:09:59And, of course, Brian will make sure she stays away from the mesh
0:09:59 > 0:10:01because the gorillas can reach through.
0:10:01 > 0:10:03So she's in no danger.
0:10:03 > 0:10:06I can see the gorillas coming out.
0:10:06 > 0:10:10Stick to the middle and keep walking till we get to the top.
0:10:10 > 0:10:11That's it.
0:10:11 > 0:10:15We need to get the food out over a big area quite quickly
0:10:15 > 0:10:17so that they don't fight about it.
0:10:20 > 0:10:23- Right, do you want to give them their grapes?- Yeah.
0:10:25 > 0:10:28The roof-feed gives the gorillas some great exercise.
0:10:29 > 0:10:32To get to the lettuce leaves, they have to climb high.
0:10:32 > 0:10:34But with arms longer than their legs,
0:10:34 > 0:10:37and many times stronger than a human,
0:10:37 > 0:10:39swinging up to get them is no problem.
0:10:39 > 0:10:42And to get the grapes that fall to the ground,
0:10:42 > 0:10:45they have to forage through the deep straw -
0:10:45 > 0:10:48just as they would in the wild.
0:10:48 > 0:10:50- Who's that one?- She's called Shumba.
0:10:52 > 0:10:56Gorillas can make 25 different grunts, growls, whines and chuckles.
0:10:56 > 0:11:00But the coughing sound is the one to watch out for.
0:11:00 > 0:11:03Just keep walking - that noise she's making
0:11:03 > 0:11:07means she's getting a bit annoyed, so we should stay out of her way.
0:11:10 > 0:11:13- They're all fighting now. - There is a hierarchy in the group,
0:11:13 > 0:11:18so the more dominant animals think they should eat all the food.
0:11:18 > 0:11:20Fortunately, most of the time it's just noise.
0:11:22 > 0:11:24- Who's this?- He's called Popper.
0:11:24 > 0:11:26Aw. He's hungry.
0:11:26 > 0:11:29He's always hungry. LUCY CHUCKLES
0:11:29 > 0:11:32With all the gorillas happily chomping away,
0:11:32 > 0:11:34our Roar ranger's work is done.
0:11:36 > 0:11:39So what does Brian think of his helper?
0:11:39 > 0:11:42She's done well. She's still got all her fingers and toes,
0:11:42 > 0:11:45so everyone's happy. She's welcome back any time.
0:11:45 > 0:11:48And did Lucy enjoy her day as a gorilla keeper?
0:11:48 > 0:11:51It was so good, cos I love monkeys
0:11:51 > 0:11:54and I love gorillas. They're just so cute.
0:11:54 > 0:11:57It's been one of the best days ever.
0:11:57 > 0:11:58# Bonkers. #
0:11:59 > 0:12:02What did the frog say when it read the paper?
0:12:02 > 0:12:03I don't know.
0:12:03 > 0:12:04"Read it".
0:12:07 > 0:12:10- BOTH:- Miaow! Miaow!
0:12:10 > 0:12:14- What does a burglar dog carry around with it?- I don't know.
0:12:14 > 0:12:15A wag bag.
0:12:20 > 0:12:21Woof, woof, woof.
0:12:21 > 0:12:23Quack, quack.
0:12:23 > 0:12:24Woof, woof, woof.
0:12:24 > 0:12:25Quack, quack, quack.
0:12:27 > 0:12:29How do you get a pig to the hospital?
0:12:30 > 0:12:32By ham-bulance.
0:12:38 > 0:12:41Now, there's some amazing news from the kudu paddock.
0:12:41 > 0:12:46Quite by chance, we spotted this baby just minutes after he was born.
0:12:46 > 0:12:49And you can see, he's already up on his feet
0:12:49 > 0:12:51and taking his first steps.
0:12:51 > 0:12:53Even if he is a bit wobbly.
0:12:55 > 0:12:59Greater Kudu are the second-biggest kind of African antelope.
0:12:59 > 0:13:02You can find them all the way from Ethiopia
0:13:02 > 0:13:04right down to South Africa.
0:13:06 > 0:13:09Just three weeks after the new baby was born here,
0:13:09 > 0:13:12head of section Joel Bunce, who we saw earlier with the tapir baby,
0:13:12 > 0:13:14has invited me to come and see him,
0:13:14 > 0:13:18as well as help hang up some browse for the adults.
0:13:18 > 0:13:21Stick it up there to keep it as high as we can.
0:13:21 > 0:13:23Yeah, got that.
0:13:23 > 0:13:24- So you got a little boy.- Yep.
0:13:24 > 0:13:27Is he out and about these days?
0:13:27 > 0:13:31He is out and about. Mum puts him in this little roundel here.
0:13:31 > 0:13:33- It's nice and overgrown.- Over here?
0:13:33 > 0:13:35Oh, in there, right.
0:13:35 > 0:13:37Obviously he's camouflaged.
0:13:37 > 0:13:41She likes to put him where there's undergrowth and places to hide.
0:13:41 > 0:13:44So he sits in there all day. We have to be very quiet.
0:13:46 > 0:13:48He's up and about in the roundel,
0:13:48 > 0:13:51so he's probably just waiting for Mum to come out.
0:13:51 > 0:13:53Hopefully, when she does, he'll join her,
0:13:53 > 0:13:56maybe have a suckle or maybe nibble on some browse.
0:13:56 > 0:13:59It's quite hard to see him. He really is well camouflaged.
0:13:59 > 0:14:01Yeah, his colour really blends in.
0:14:01 > 0:14:03He's a sort of dull, browny-grey colour,
0:14:03 > 0:14:06and that's perfect to fit in with the vegetation in there.
0:14:06 > 0:14:08So the browse is in position.
0:14:08 > 0:14:10Obviously, he'll want his breakfast,
0:14:10 > 0:14:13- so shall we get out of here, so Mum can come over?- Yep.
0:14:13 > 0:14:16Hopefully, we'll get a closer look as well.
0:14:22 > 0:14:25OK, the kudu are out and enjoying their browse
0:14:25 > 0:14:29and we've gone to the area where the little baby was,
0:14:29 > 0:14:31and as soon as we approached, he's bounced out
0:14:31 > 0:14:33and gone off to Mum.
0:14:33 > 0:14:35Is that him just over there?
0:14:35 > 0:14:38Yeah, he's just going over to the herd now.
0:14:38 > 0:14:40I'm actually really surprised at how big he is.
0:14:40 > 0:14:42You said he was three weeks old.
0:14:42 > 0:14:45Yeah, he was a particularly big calf.
0:14:45 > 0:14:48We haven't had one that big for a while.
0:14:48 > 0:14:51So... That's not bad for three weeks, is it?
0:14:51 > 0:14:53We were really surprised before
0:14:53 > 0:14:56when you led us over there and said, "The baby's in there."
0:14:56 > 0:14:59Is this what they'd do in the wild,
0:14:59 > 0:15:02just leave them somewhere, hiding? And how long for?
0:15:02 > 0:15:06That's right, they'd leave them somewhere with plenty of undergrowth,
0:15:06 > 0:15:08where their camouflage blends in,
0:15:08 > 0:15:10and they hopefully wouldn't be found by predators.
0:15:10 > 0:15:13It's the only way. If they were up with the herd
0:15:13 > 0:15:16and had to run from something, hyenas or lions,
0:15:16 > 0:15:18the calf wouldn't keep up and would be easy prey.
0:15:18 > 0:15:21Well, it's great to see the little fella,
0:15:21 > 0:15:23and I think at his size, it's probably not long
0:15:23 > 0:15:25before he gets massive horns like his dad.
0:15:25 > 0:15:29His dad is probably about seven or eight years old now,
0:15:29 > 0:15:31so he's got a bit of growing to do,
0:15:31 > 0:15:35but, yeah, hopefully he'll take after his dad and be that big.
0:15:35 > 0:15:37I've got nothing else to do today,
0:15:37 > 0:15:41so I'm just going to sit around here and watch his horns grow.
0:15:50 > 0:15:52Down at the black rhino paddock,
0:15:52 > 0:15:55there could be another little one on the way.
0:15:55 > 0:15:58They've never had a baby rhino born here before,
0:15:58 > 0:16:02but now keeper Helen Rhodes says that Rufiji is pregnant.
0:16:02 > 0:16:05Rufiji will be a first-time mum. It's a learning curve for us,
0:16:05 > 0:16:08and it should be great to have rhino babies for the first time.
0:16:08 > 0:16:12Helen won't have far to go for advice, though.
0:16:12 > 0:16:15Their sister park down the road has been very successful
0:16:15 > 0:16:17at breeding black rhinos,
0:16:17 > 0:16:19with a whopping 29 births over the years.
0:16:22 > 0:16:25They've even returned some of them to Africa,
0:16:25 > 0:16:30which is fantastic, because there are only 3,600 left in the wild,
0:16:30 > 0:16:33so every baby born in captivity is very precious.
0:16:35 > 0:16:38To make the news even more exciting,
0:16:38 > 0:16:42Helen suspects their other female, Salome, may be pregnant too.
0:16:42 > 0:16:45But there's only one way to find out for sure - collect her poo.
0:16:45 > 0:16:47This isn't particularly nice,
0:16:47 > 0:16:50but it is essential to find out if a rhino's pregnant.
0:16:50 > 0:16:54The poo samples Helen is collecting will be sent away to a laboratory,
0:16:54 > 0:16:58where the scientists will be able to tell from them if she is pregnant.
0:16:59 > 0:17:01Ah, I love this job(!)
0:17:01 > 0:17:05Helen had to do the same thing for Rufiji last year,
0:17:05 > 0:17:09but she's now nearly halfway through her 15-month pregnancy.
0:17:10 > 0:17:14It's been going well, but something very worrying has happened.
0:17:15 > 0:17:18Vungu, the male, has started to threaten Rujiji.
0:17:19 > 0:17:22We've found that at feed times, he's been quite aggressive
0:17:22 > 0:17:24and she's been backing away from him,
0:17:24 > 0:17:26so we think she's trying to separate herself.
0:17:28 > 0:17:32In the wild, Vungu would have gone off to live on his own after mating.
0:17:33 > 0:17:35They have a big paddock here,
0:17:35 > 0:17:39but if he does decide to pick a fight with Rufiji,
0:17:39 > 0:17:41he's equipped with an awesome horn.
0:17:41 > 0:17:43If they were sparring and it got out of control,
0:17:43 > 0:17:46it could do a lot of damage. That's the last thing we want.
0:17:46 > 0:17:49It could be a disaster.
0:17:49 > 0:17:52Rufiji might lose her baby, or even be killed.
0:17:52 > 0:17:55So Helen needs to quickly get the pregnant cow away from Vungu
0:17:55 > 0:17:57and safely into a separate paddock.
0:17:59 > 0:18:01Rufiji, come in.
0:18:01 > 0:18:03Good girl, come on then.
0:18:03 > 0:18:07But Rufiji doesn't want to move, even if it is for her own good.
0:18:07 > 0:18:09Helen's got a big problem -
0:18:09 > 0:18:12a one-ton problem, in fact.
0:18:14 > 0:18:16They can be extremely stubborn,
0:18:16 > 0:18:19especially if we try to get them out of a paddock they're happy in.
0:18:19 > 0:18:20Fij! Come on, then.
0:18:20 > 0:18:24We'll come back to see if Helen can get Rufiji safely away
0:18:24 > 0:18:26before a fight breaks out.
0:18:30 > 0:18:34Pay attention out there, all you online gamers.
0:18:34 > 0:18:36This is the moment you've been waiting for.
0:18:36 > 0:18:39Today's very valuable cheat code is:
0:18:41 > 0:18:43It really is valuable,
0:18:43 > 0:18:46because it will unlock food and treats
0:18:46 > 0:18:50for the animals in your online wildlife park.
0:19:05 > 0:19:07Ah, the great outdoors.
0:19:07 > 0:19:09The smell of fresh, clean air
0:19:09 > 0:19:12and doing things like roasting marshmallows on an open fire.
0:19:12 > 0:19:14We're not really in the great outdoors.
0:19:14 > 0:19:16We're at the elly paddock
0:19:16 > 0:19:19and that fire there is made out of elephant poo.
0:19:20 > 0:19:24Which is not quite as gross as it might sound. Isn't that right, Sam?
0:19:24 > 0:19:25That's right.
0:19:25 > 0:19:29Tell us why we're cooking these marshmallows on some elephant poo.
0:19:29 > 0:19:32We really wanted to see how well it burns.
0:19:32 > 0:19:36Out in Africa, the local people use it to make their fires.
0:19:36 > 0:19:40It's a better way, rather than to go and cut down trees and stuff.
0:19:40 > 0:19:43So we just wanted to see how quickly it burned.
0:19:43 > 0:19:47Wow, so it burns really well. Why does elephant poo burn?
0:19:47 > 0:19:53If you think about it, elephants eat a lot of wood products, hay,
0:19:53 > 0:19:55and most of what they eat comes out in their poo.
0:19:55 > 0:19:58They have a fairly inefficient digestive system,
0:19:58 > 0:20:01so when their poo's dried out, it will burn quite happily.
0:20:01 > 0:20:03That's amazing. So as well as anything else,
0:20:03 > 0:20:06elephant poo is quite good for the environment?
0:20:06 > 0:20:08Definitely. It's got all the nutrients in it,
0:20:08 > 0:20:12all the nutrients go back into the ground, so other things grow.
0:20:12 > 0:20:14They transfer seeds everywhere.
0:20:14 > 0:20:16So how many elephants are in the paddock?
0:20:16 > 0:20:18We've got a herd of 14.
0:20:18 > 0:20:23So when we pick up, we get roughly two dumper-fulls a day.
0:20:23 > 0:20:25- That is a lot of poo.- Yep.
0:20:25 > 0:20:28Have you got a whole separate "poo team"?
0:20:28 > 0:20:30Unfortunately not, no. We have to pick it up,
0:20:30 > 0:20:33feed them, move them around. It's all us.
0:20:35 > 0:20:38So if we opened up this dung pile here,
0:20:38 > 0:20:39what would we find in it?
0:20:39 > 0:20:44You would find bits of hay, orange, apple, beetroot,
0:20:44 > 0:20:48anything that hasn't been digested. They could be whole pieces of fruit.
0:20:48 > 0:20:52They pretty much poo out 40% of what they eat.
0:20:52 > 0:20:53So what happens to the 60%?
0:20:53 > 0:20:57- That goes as nutrients that keep the elephant going?- That's right.
0:20:57 > 0:21:01Whole industries, in the olden days, were built on things like coal.
0:21:01 > 0:21:06If elephant poo is the new coal, I guess this is very valuable stuff?
0:21:06 > 0:21:08Oh, definitely.
0:21:08 > 0:21:13Probably each elephant will produce 40 to 50 kilos a day.
0:21:13 > 0:21:1840 to 50 kilos per day... How much do you weigh?
0:21:18 > 0:21:20I weigh about 57 kilos.
0:21:20 > 0:21:24Wow, so almost as much as you in poo per day.
0:21:24 > 0:21:27- Thank you. - Sorry, not very flattering, is it?
0:21:27 > 0:21:30Sam, thanks, I've learned something.
0:21:30 > 0:21:33Who would have thought elephant poo could be so useful?
0:21:33 > 0:21:35Come on, guys, another log on the fire.
0:21:44 > 0:21:46Back down at the black rhino paddock,
0:21:46 > 0:21:50Helen's come up with a plan to separate the pregnant female Rufiji
0:21:50 > 0:21:55from Vungu, the male who's been threatening her and her unborn baby.
0:21:55 > 0:21:59It's breakfast time, so I'm hoping that if I put the food out,
0:21:59 > 0:22:02they'll come down and Rufiji will come first.
0:22:02 > 0:22:04Fingers crossed, we'll see what happens.
0:22:04 > 0:22:06Fij, you coming?
0:22:07 > 0:22:12This is Vungu. Might cause a bit of a problem if he comes through first.
0:22:12 > 0:22:13Fij, come on, then.
0:22:15 > 0:22:17But Rufiji doesn't come on.
0:22:17 > 0:22:19And as Helen feared,
0:22:19 > 0:22:22it's the troublesome bull Vungu who comes through first.
0:22:22 > 0:22:26And there's no way she can keep him in the smaller enclosure.
0:22:26 > 0:22:29The problem now is because Vungu's in the paddock,
0:22:29 > 0:22:31Fij won't actually come through the gates,
0:22:31 > 0:22:34cos there's a big chance that he could actually go for her.
0:22:36 > 0:22:37SNORTS
0:22:37 > 0:22:40He's showing signs of aggression already.
0:22:41 > 0:22:44That shows Helen a way to get him away from the gate
0:22:44 > 0:22:45so the girls can come in.
0:22:45 > 0:22:48Do you guys just want to walk down with me?
0:22:49 > 0:22:51Come on, Vungu.
0:22:53 > 0:22:55Fij, come on!
0:22:56 > 0:22:57It works.
0:22:57 > 0:23:00He's moved far enough for the girls to feel safe
0:23:00 > 0:23:03about coming into the paddock as well.
0:23:03 > 0:23:05So now Helen has got Rufiji in here,
0:23:05 > 0:23:10all she has to do is get Vungu and the other female, Salome, out again.
0:23:11 > 0:23:14He's definitely not in the mood to come when he's called,
0:23:14 > 0:23:19but she knows one thing that he won't be able to resist.
0:23:19 > 0:23:22A pile of bananas.
0:23:26 > 0:23:27Vungu, come on!
0:23:27 > 0:23:29Good lad.
0:23:29 > 0:23:33Rhinos have very poor eyesight, but a fantastic sense of smell.
0:23:34 > 0:23:36So they definitely know what's out there.
0:23:36 > 0:23:38Salome, come on.
0:23:38 > 0:23:41Hopefully, this time Rufiji will be last
0:23:41 > 0:23:43and Helen can shut her in.
0:23:43 > 0:23:44That's Vungu through.
0:23:46 > 0:23:48This is Salome coming up behind him now.
0:23:48 > 0:23:51Helen's plan's working.
0:23:51 > 0:23:53Good girl, Salome.
0:23:53 > 0:23:56At long last, all the rhinos are where Helen wants them.
0:23:58 > 0:24:02Until the poo samples come back to confirm whether Salome is pregnant,
0:24:02 > 0:24:04she'll stay with Vungu the bull,
0:24:04 > 0:24:07because there's no chance SHE'LL get bullied.
0:24:07 > 0:24:10Salome takes absolutely no rubbish off Vungu.
0:24:10 > 0:24:13If that was Fij, he'd have chased her, roared at her,
0:24:13 > 0:24:15but Salome doesn't care, she's really cool.
0:24:15 > 0:24:19Mum-to-be Rufiji may have missed out on the bananas for now,
0:24:19 > 0:24:22but at least she's safely in her own paddock.
0:24:23 > 0:24:25Hopefully, she'll be happy. We'll observe her,
0:24:25 > 0:24:27make sure she's not stressed.
0:24:27 > 0:24:30In the wild, black rhinos live alone,
0:24:30 > 0:24:33so it's perfectly natural for her to be by herself.
0:24:33 > 0:24:35But with Helen on hand,
0:24:35 > 0:24:39she'll be getting lots of attention throughout her pregnancy.
0:24:39 > 0:24:42If you get her on her own, and she's not got the others bothering her,
0:24:42 > 0:24:46she loves a good scratch. She's very friendly, really.
0:24:46 > 0:24:49We'll catch up with the pregnant Rufiji's progress
0:24:49 > 0:24:51later in the series,
0:24:51 > 0:24:55and with luck, there'll soon be another cute little baby,
0:24:55 > 0:24:57just like this one, playing in the park.
0:25:09 > 0:25:12Before we leave, we thought we'd pop to the Discovery Zone
0:25:12 > 0:25:14and meet keeper Chris
0:25:14 > 0:25:17and one of the most endangered reptiles on the planet.
0:25:17 > 0:25:19Hiya, Chris, you all right?
0:25:19 > 0:25:22He's amazing, looks like something out of Jurassic Park.
0:25:22 > 0:25:24What have we got here?
0:25:24 > 0:25:28This is Brig. That's not the type of animal, that's his name.
0:25:28 > 0:25:30He is a rhino iguana.
0:25:30 > 0:25:33You've got to tell us, why's he called a rhino iguana?
0:25:33 > 0:25:37It's quite obvious. I bet if you look at him, you can work it out.
0:25:37 > 0:25:38Cos he's big and grey?
0:25:38 > 0:25:40THEY LAUGH
0:25:40 > 0:25:43- It's the horns, innit, right? - All to do with this.
0:25:43 > 0:25:47Where is from in the wild? I don't know anything about these guys.
0:25:47 > 0:25:50He's a type of Island Iguana.
0:25:50 > 0:25:52Comes from the Dominican Republic.
0:25:52 > 0:25:54But there's plenty of different types
0:25:54 > 0:25:57of Island Iguanas around the same area.
0:25:57 > 0:26:00I can't believe how soft he is.
0:26:00 > 0:26:02- Look at his eyes, he's really enjoying it.- He is!
0:26:02 > 0:26:05That's what rhinos do as well.
0:26:05 > 0:26:08When he first came, he had a little bit of an attitude,
0:26:08 > 0:26:10but over time, he's calmed down
0:26:10 > 0:26:13and you can do that and he doesn't care at all.
0:26:13 > 0:26:17We mentioned he's one of the most endangered reptiles on the planet.
0:26:17 > 0:26:19- Is that actually true? - It certainly is.
0:26:19 > 0:26:23The Island Iguanas, as a group, are incredibly endangered.
0:26:23 > 0:26:25Why is that?
0:26:25 > 0:26:29It's completely down to introduced species.
0:26:29 > 0:26:32People have introduced pigs and dogs onto the islands,
0:26:32 > 0:26:34and these animals hunt the iguanas,
0:26:34 > 0:26:37and they're direct competition for food as well.
0:26:37 > 0:26:42- What's the future for Brigs now? - Brigs is getting an old man now.
0:26:42 > 0:26:46But we were hoping that we might be able to get a female for him.
0:26:46 > 0:26:48If we do, that'd be fantastic,
0:26:48 > 0:26:51but if not, he's quite happy here.
0:26:51 > 0:26:55He's got his food and he has a bit of a scratch now and then.
0:26:55 > 0:26:57What an amazing animal.
0:26:57 > 0:26:59He is. Chris, thanks so much.
0:26:59 > 0:27:01We're going to hang around with Brigs
0:27:01 > 0:27:04while you guys check out what's on the next episode.
0:27:06 > 0:27:08There's an emergency in the parks,
0:27:08 > 0:27:13where a one-ton rhino's got his head stuck after being darted.
0:27:13 > 0:27:17The only possible way to free him is to push from one end
0:27:17 > 0:27:20and pull from the other. But can they do it before he passes out?
0:27:21 > 0:27:25And the keepers are hoping that two pancake tortoises will mate,
0:27:25 > 0:27:27but he seems a bit snappy.
0:27:28 > 0:27:31That's all in the next Roar.
