0:00:02 > 0:00:05An African wild dog called Dead Eye Dave
0:00:05 > 0:00:09has to be knocked out for a life-saving operation.
0:00:09 > 0:00:14But will his brother attack him when he comes back to the enclosure?
0:00:38 > 0:00:40Welcome to Roar. I'm Johny.
0:00:40 > 0:00:44I'm Rani. And this chilled-out fella is the red-footed tortoise.
0:00:44 > 0:00:48These guys are from South America and they draw their name
0:00:48 > 0:00:52from their red and orange scales on their head, feet and tails.
0:00:52 > 0:00:57All tortoises are slow, but the red-footed tortoise, on average,
0:00:57 > 0:01:00walks less than a kilometre an hour.
0:01:00 > 0:01:04We'd better leave him here because we've got an action-packed show,
0:01:04 > 0:01:06so come on!
0:01:11 > 0:01:13'Coming up on today's show...
0:01:13 > 0:01:17'Stand by for one of the longest and thinnest tongues in the world.
0:01:17 > 0:01:22- 'It's amazing.'- I'd believe anything about these creatures after today!
0:01:22 > 0:01:25'Are the lion-tailed macaques smart enough
0:01:25 > 0:01:28'and strong enough to break into coconuts?'
0:01:28 > 0:01:31They're all fighting for it now!
0:01:31 > 0:01:34'And how will the black-and-white ruffed lemurs keeper get on
0:01:34 > 0:01:39- 'when he faces...'- The killer question!- Oh, that's a good one.
0:01:39 > 0:01:44'But first, the extraordinary story of Dead Eye Dave.'
0:01:50 > 0:01:53African hunting dogs are some of the wildest
0:01:53 > 0:01:57and most endangered creatures in the world.
0:01:57 > 0:02:00In the wild, a pack of them are almost invincible,
0:02:00 > 0:02:04able to hunt and kill animals many times their own size.
0:02:04 > 0:02:08But like any puppies, they're helpless when they're born,
0:02:08 > 0:02:10especially when they're orphans.
0:02:10 > 0:02:14Two years ago, the keepers had to work round the clock
0:02:14 > 0:02:17to try and save this litter of 14 pups.
0:02:17 > 0:02:19Here we go then -
0:02:19 > 0:02:22a five-day-old, wriggly, hunting dog puppy.
0:02:22 > 0:02:27Believe it or not, this is actually probably about twice the size
0:02:27 > 0:02:30of what they were when they were first born.
0:02:30 > 0:02:35Chris and the team did everything their mother would have done.
0:02:35 > 0:02:37Well, almost everything.
0:02:37 > 0:02:41In the first stages of their lives, they don't wee and poo by themselves.
0:02:41 > 0:02:43Normally, Mum stimulates them.
0:02:43 > 0:02:48She'll lick their bits and pieces to stimulate them to wee and poo.
0:02:48 > 0:02:53I'm not going to do that, so instead I'm using a piece of cotton wool.
0:02:53 > 0:02:57But without their mother, their chances never looked good.
0:02:57 > 0:02:59Despite all the keepers' care,
0:02:59 > 0:03:02eight of them died over the next few weeks.
0:03:02 > 0:03:06Head of section Rich Barnes was left with six - four girls and two boys.
0:03:06 > 0:03:10But at least the survivors looked strong and healthy.
0:03:10 > 0:03:12They're proper wild little dogs
0:03:12 > 0:03:17and since about two weeks old, they've been pulling each other over
0:03:17 > 0:03:20and trying to tear each other's ears off and stuff,
0:03:20 > 0:03:22so they're already pretty cool.
0:03:22 > 0:03:27You can see how they can turn into these ferocious killing machines.
0:03:27 > 0:03:32From the day they were born, the two males were a dangerous double act.
0:03:34 > 0:03:37And look at them now, just two years on!
0:03:37 > 0:03:41They're called Chobe and Dead Eye Dave
0:03:41 > 0:03:45who, as the name suggests, always had a bit of a bad eye.
0:03:45 > 0:03:50But what was a nickname has now turned into a problem.
0:03:50 > 0:03:54Keeper Jess noticed something strange going on with Dave's eye
0:03:54 > 0:03:56and called in the vet.
0:03:56 > 0:04:00Today, we're going to knock out one of the wild dogs
0:04:00 > 0:04:04from the hand-reared lot that were born here two years back
0:04:04 > 0:04:07to try and find out what's going on with his eye.
0:04:07 > 0:04:10It's changed colour a few times in the last few weeks,
0:04:10 > 0:04:15so Jane the vet will have a look to find out what's happening with it.
0:04:15 > 0:04:19Separating Dave from Chobe may cause them to fight later on,
0:04:19 > 0:04:22so Jane will sedate him and check out the eye
0:04:22 > 0:04:24as close as possible to his brother.
0:04:24 > 0:04:26- Is this him here?- Yeah.
0:04:26 > 0:04:30Kerry, Jane's assistant, is here with a medical kit.
0:04:30 > 0:04:34With luck, they'll be able to treat him quickly on the spot.
0:04:34 > 0:04:37Good boy!
0:04:38 > 0:04:40DOG WHIMPERS
0:04:40 > 0:04:42I went for a shoulder shot.
0:04:42 > 0:04:45As usual, Jane was bang on target
0:04:45 > 0:04:49and Dave should go safely to sleep in this part of the enclosure.
0:04:49 > 0:04:53Unless we find anything worrying, we'll do the whole sedation here.
0:04:53 > 0:04:58If we find anything worrying, we may transfer him to the vet hospital,
0:04:58 > 0:05:01but hopefully, it'll just be a quick procedure here.
0:05:01 > 0:05:05The drugs Jane uses are powerful, but Rich goes first.
0:05:05 > 0:05:09If Dave is still awake, he'll be very dangerous.
0:05:09 > 0:05:12- The towel is to keep light from his eyes.- Wait there a minute.
0:05:12 > 0:05:17We're just waiting to make sure that the sedation is fully applied,
0:05:17 > 0:05:20then Jane will start having a look at him.
0:05:20 > 0:05:24I think you're good to come in, Kerry. I think he's doing very well.
0:05:26 > 0:05:29Jane immediately checks out the problem eye
0:05:29 > 0:05:32and it doesn't look good.
0:05:32 > 0:05:34- Is that bad?- Yeah.
0:05:35 > 0:05:39- You see where it's beginning to erode in the surface?- Yeah.
0:05:39 > 0:05:42I think the whole thing needs to come out,
0:05:42 > 0:05:46- so it does need to be done in the vet hospital.- OK.
0:05:46 > 0:05:48We'll have to take him, do it
0:05:48 > 0:05:52- and bring him back as quickly as possible.- Yeah.
0:05:52 > 0:05:55If we've got to do that, we've got to do that.
0:05:55 > 0:05:58The problem is much worse than they thought.
0:05:58 > 0:06:01We're transferring the dog to the vet hospital.
0:06:01 > 0:06:06The eye is very badly infected and we need to remove the eye.
0:06:08 > 0:06:12It's bad news and the operation is risky, but if they don't do it,
0:06:12 > 0:06:16the infection could spread and kill him anyway.
0:06:28 > 0:06:32Oh, sorry, I'm just measuring my tongue
0:06:32 > 0:06:36because I've heard some information that's going to set tongues wagging.
0:06:36 > 0:06:40My tongue is only six centimetres long,
0:06:40 > 0:06:44but an anteater's tongue is an incredible 60 centimetres long.
0:06:44 > 0:06:48I'm here with Head of Hoofstock Joel Bunce. Joel, that can't be right.
0:06:48 > 0:06:52- I'm afraid it's true.- Can we measure that out on my tape measure here?
0:06:52 > 0:06:5560 centimetres is that long!
0:06:55 > 0:06:58Why does an anteater's tongue need to be that long?
0:06:58 > 0:07:01Because he feeds primarily on termites.
0:07:01 > 0:07:05So what he needs to do is raid a termite mound and they're huge.
0:07:05 > 0:07:08They build huge tunnels into them,
0:07:08 > 0:07:12so he needs to be able to get all the way down to get his food.
0:07:12 > 0:07:16Why isn't he called a termite-eater, rather than an anteater?
0:07:16 > 0:07:19Termites and ants are basically the same thing.
0:07:19 > 0:07:21He eats a lot of them, 30,000,
0:07:21 > 0:07:25so the longer the tongue, the more food he's able to get.
0:07:25 > 0:07:27I noticed him in this enclosure.
0:07:27 > 0:07:31He's one of the strangest animals on the park. He looks so bizarre.
0:07:31 > 0:07:33Where do you find one in the wild?
0:07:33 > 0:07:36They're quite widespread in South America.
0:07:36 > 0:07:41There are other types of anteater, but these are the biggest.
0:07:41 > 0:07:45I still can't believe that his tongue really is 60 centimetres,
0:07:45 > 0:07:50so I've had a word with the Roar boffins to devise a contraption
0:07:50 > 0:07:52to see just how long his tongue is.
0:07:52 > 0:07:57So can we try and get him outside with our contraption?
0:07:57 > 0:08:01- Yeah, that's no problem.- Brilliant. Join us later to find out
0:08:01 > 0:08:06if an anteater's tongue really is as long as they say... No way!
0:08:08 > 0:08:12- What happened when the cat swallowed a ball of wool?- I don't know.
0:08:12 > 0:08:14He had mittens!
0:08:15 > 0:08:18Raargh! Raargh!
0:08:20 > 0:08:22Why was the mother glow-worm unhappy?
0:08:22 > 0:08:25Because her children weren't very bright.
0:08:25 > 0:08:27Cuh, cuh, cuh!
0:08:27 > 0:08:30How do you get an elephant into a matchbox?
0:08:30 > 0:08:33Take all the matches out first.
0:08:35 > 0:08:37Oh, rubbish!
0:08:40 > 0:08:44The lion-tailed macaques can make a meal out of anything.
0:08:44 > 0:08:47Today, we're going to be going nuts, literally, with coconuts.
0:08:47 > 0:08:51I'm here with keeper Liam. I've brought the coconuts down
0:08:51 > 0:08:55because we are going to be giving these to the lion-tailed macaques.
0:08:55 > 0:08:59OK, how are we going to crack these open to give it to them?
0:08:59 > 0:09:03We don't need to do that. They'll do it for us. Easy!
0:09:03 > 0:09:06Liam, Liam, Liam, listen to this.
0:09:06 > 0:09:10Hard! Look at those things. They're tiny! How are they going to do it?
0:09:10 > 0:09:14They are stronger than they look and they are very clever.
0:09:14 > 0:09:18They will get into them no problem, I reckon, within a few minutes.
0:09:18 > 0:09:22I'm placing one down here. They're all watching us.
0:09:22 > 0:09:26- Do they know this is a treat? Have they ever had coconuts before?- Yeah.
0:09:26 > 0:09:29But any time any activity goes on outside,
0:09:29 > 0:09:33it means something is going to change and they'll always investigate it.
0:09:33 > 0:09:38They've seen us walking around with coconuts, so they know what it is.
0:09:38 > 0:09:42- Are they curious? Shall I place one here?- Yeah, under the bush.
0:09:42 > 0:09:46If he or she doesn't find this, I'm going to blame you.
0:09:46 > 0:09:50- Let's pop another one over here on these branches.- It fits perfectly.
0:09:50 > 0:09:54You've given them coconuts before. How do they get into them?
0:09:54 > 0:09:58I'm pretty sure they'll stand up on their back two feet,
0:09:58 > 0:10:01then smash them on the ground, something hard.
0:10:01 > 0:10:05A lot of the youngsters will just use them as toys.
0:10:05 > 0:10:09Coconuts are quite rich. Will it be OK for their digestive system?
0:10:09 > 0:10:12- I've heard a rumour! - Yeah, that might go through.
0:10:12 > 0:10:17- We only give them a little amount because it is quite rich.- Right.
0:10:17 > 0:10:21- It can go through them if they eat lots of coconuts.- They get the poos.
0:10:21 > 0:10:25- Yeah.- It's a little bit of a treat, so they're all in position,
0:10:25 > 0:10:29the lion-tailed macaques, and they are a bit fierce when we're in here,
0:10:29 > 0:10:34- so the best place to watch them... - Is definitely outside the enclosure
0:10:34 > 0:10:38- because they don't like us being around their coconuts.- Fair enough!
0:10:38 > 0:10:41We'll make our way outside. Join us later on
0:10:41 > 0:10:45when the lion-tailed macaques can be in here enjoying their coconuts.
0:10:47 > 0:10:51Down at the vet centre, Dead Eye Dave is on the operating table.
0:10:51 > 0:10:56The two-year-old African hunting dog has a bad eye,
0:10:56 > 0:11:00which vet Jane Hopper needs to remove as quickly as possible
0:11:00 > 0:11:03because otherwise, Dave may well die.
0:11:03 > 0:11:05The eye is very, very ulcerated
0:11:05 > 0:11:08and it's so ulcerated, the eye is actually dying.
0:11:08 > 0:11:12If we leave it, the eye may burst, which is horrible,
0:11:12 > 0:11:16so we need to remove the eye before anything really awful happens.
0:11:16 > 0:11:19Jane has had to sedate Dave to operate,
0:11:19 > 0:11:23but he can't pant which is how dogs control their temperature.
0:11:23 > 0:11:27Vet assistant Kerry has noticed that he's getting hot,
0:11:27 > 0:11:31which could be dangerous, so she's covering him with a cold, wet towel.
0:11:35 > 0:11:40Dead Eye Dave is a favourite of Head of Section Rich Barnes
0:11:40 > 0:11:42because he helped to hand-rear him.
0:11:42 > 0:11:46This is one of the hand-raised ones from 2007.
0:11:46 > 0:11:48All the animals are quite special,
0:11:48 > 0:11:52but we have a bit more of a connection with these guys,
0:11:52 > 0:11:56so we want to do everything right by them and we're a bit worried.
0:11:56 > 0:12:00Hopefully, he'll get through the operation and everything will be OK.
0:12:02 > 0:12:04So the sooner it's done, the better,
0:12:04 > 0:12:07but at least Kerry has good news.
0:12:07 > 0:12:09His temperature's back to normal.
0:12:09 > 0:12:13The cold towel and the ice packs have reduced his temperature slowly,
0:12:13 > 0:12:16so that's all good now.
0:12:16 > 0:12:20We won't show you what Jane's doing because it's pretty gruesome.
0:12:22 > 0:12:24But at last, she's finished.
0:12:24 > 0:12:29Good work, yeah. If I ever want an eye removed, I'll get Jane to do it.
0:12:29 > 0:12:31With the operation a success,
0:12:31 > 0:12:35the priority is now to get Dave back to his enclosure
0:12:35 > 0:12:38as quickly as possible.
0:12:38 > 0:12:41But will his brother accept him or attack him?
0:12:41 > 0:12:45The other boy's a bit nervous because we're all here.
0:12:45 > 0:12:49When we go, they'll sit next to each other either side of the fence.
0:12:49 > 0:12:51We'll give it a few hours,
0:12:51 > 0:12:54try not to leave it too long, then mix them back together.
0:12:54 > 0:12:58There's always a danger that they could attack each other.
0:12:58 > 0:13:03We have to do what we have to do, so we'll just have to see what happens.
0:13:03 > 0:13:05Everyone is very nervous.
0:13:05 > 0:13:08Dave's weak and his life could be in the balance.
0:13:19 > 0:13:23Great anteaters must be amongst the weirdest looking creatures on Earth.
0:13:25 > 0:13:29But there's a good reason why they have that super-long snout
0:13:29 > 0:13:32with a little mouth and savage front claws.
0:13:32 > 0:13:36They get their food by breaking into rock-hard termite mounds,
0:13:36 > 0:13:41sticking their noses in and scoffing all the ant-like termites inside.
0:13:42 > 0:13:45I'm still outside the anteater enclosure.
0:13:45 > 0:13:49An anteater's got a tongue that's around 60 centimetres long,
0:13:49 > 0:13:53so we've devised a contraption that will show us just how long it is.
0:13:53 > 0:13:56Joel, what do you think will happen?
0:13:56 > 0:13:58I think he will stick his tongue
0:13:58 > 0:14:02into those clear plastic tunnels with the mealworms in and eat them all.
0:14:02 > 0:14:07- His tongue can stretch that far into the tube?- Yeah, it certainly will.
0:14:07 > 0:14:10- What have we got in there? - We have mealworms.
0:14:10 > 0:14:14- Gross! Are these one of his favourite foods?- Yes, he loves them.
0:14:14 > 0:14:19He's coming out now. He's going straight over to our contraption.
0:14:19 > 0:14:23Has he got a good sense of smell? He's got a long nose. Look at this.
0:14:23 > 0:14:27- I saw something coming through there.- Yeah, it is now.
0:14:27 > 0:14:30- No way!- That's the shorter tunnel.
0:14:30 > 0:14:34- That will be no problem for him.- It's unreal. It's like a little whip.
0:14:34 > 0:14:39- Yes, exactly.- It seems like the worms are just sticking to the tongue.
0:14:39 > 0:14:43Has he got a sticky tongue or any special adaptations?
0:14:43 > 0:14:45Yeah, the tongue is quite sticky,
0:14:45 > 0:14:49so that helps keep a grip on the termites or insects he's eating,
0:14:49 > 0:14:52just long enough to get it back into his mouth.
0:14:52 > 0:14:57I never realised how slim it would be. It's not like a regular tongue.
0:14:57 > 0:14:59No, it's very small and string-like.
0:14:59 > 0:15:03He's got this long snout. Is that a mouth or a nose? What is it?
0:15:03 > 0:15:05It's a combination of the two.
0:15:05 > 0:15:10It's mostly nose, but he's got a very small mouth right at the end.
0:15:10 > 0:15:14- It's only small because he's eating small insects.- Has he got any teeth?
0:15:14 > 0:15:16No real teeth as such.
0:15:16 > 0:15:19Right at the back of the snout or the mouth,
0:15:19 > 0:15:24he's got a little plate which is used for crushing termites or insects
0:15:24 > 0:15:27just small enough to swallow them into his stomach.
0:15:27 > 0:15:31Look at that! We've got an amazing shot. He's going for worms.
0:15:31 > 0:15:35But that tongue looks like a worm itself. Look at that giant worm!
0:15:35 > 0:15:39- Oh, my gosh! That's easily 60 centimetres.- Yeah.
0:15:39 > 0:15:44Wow! Do these guys eat a lot? Are they constantly foraging for food?
0:15:44 > 0:15:49Well, they have to really eat about 30,000 termites a day to survive,
0:15:49 > 0:15:51which is a huge amount.
0:15:51 > 0:15:55Why do you think they love the termites so much?
0:15:55 > 0:15:58Is it just something that's naturally found where they are?
0:15:58 > 0:16:00It's just how they've evolved.
0:16:00 > 0:16:04They've become very specialised in what they do.
0:16:04 > 0:16:08There's no competition for termites. Nothing else eats them in their area.
0:16:08 > 0:16:11Their sole focus is on doing that.
0:16:11 > 0:16:14That's how they've lasted all this time
0:16:14 > 0:16:17because they've just specialised in one thing.
0:16:17 > 0:16:21That tongue is making short work of those mealworms. It moves so fast.
0:16:21 > 0:16:25Yeah, it's very quick, reputedly 150 times a minute.
0:16:25 > 0:16:29I've not counted myself, but I can quite believe it, yeah.
0:16:29 > 0:16:32I'd believe anything about these creatures after today.
0:16:32 > 0:16:35Before this, I thought you were maybe lying.
0:16:35 > 0:16:3960 centimetres is a lot, but after seeing this, I believe you.
0:16:39 > 0:16:43Thanks for letting us get so close to the amazing anteater.
0:16:45 > 0:16:49Now it's time to pick up a pen or fire up your computer.
0:16:49 > 0:16:53That's right because here is today's cheat code.
0:16:53 > 0:16:55It's "coral762".
0:16:55 > 0:16:59Type it in carefully because only this exact code
0:16:59 > 0:17:01will unlock today's food and treats
0:17:01 > 0:17:05for the animals in your wildlife park.
0:17:16 > 0:17:20Earlier in the show, myself and keeper Liam placed some coconuts
0:17:20 > 0:17:23in the lion-tailed macaques' enclosure. They've all got one.
0:17:23 > 0:17:26Even the little ones grabbed them.
0:17:26 > 0:17:29I thought Spock the big male would come along,
0:17:29 > 0:17:31but Bootsman is the obvious one.
0:17:31 > 0:17:34Look at that! You said they'd walk on two legs.
0:17:34 > 0:17:39You see them running away, grabbing what they can and off they go.
0:17:39 > 0:17:42Wow! It's great to see them on two legs.
0:17:42 > 0:17:47- Would they have a need to do that in the wild?- Yeah, they will do that.
0:17:47 > 0:17:52They do it to gain a higher vantage point when searching for food.
0:17:52 > 0:17:55We scatter all the food around, so they forage.
0:17:55 > 0:17:58They'll stand up on two legs to get a higher vantage point.
0:17:58 > 0:18:03They do it in the wild for the same thing and to look out for predators.
0:18:03 > 0:18:06- Do they know they're edible products?- Yeah.
0:18:06 > 0:18:10When they first had them, they probably would've investigated them,
0:18:10 > 0:18:13destroyed them, then realised these were quite tasty.
0:18:13 > 0:18:15They know they're nice now,
0:18:15 > 0:18:19so you can see them all desperately trying to get into them.
0:18:19 > 0:18:24It's amazing to see their balance when they're holding something.
0:18:24 > 0:18:28- They're just jumping around. - Really agile.- Look at that.
0:18:28 > 0:18:32He's definitely built to move around like that. He does that quite often.
0:18:32 > 0:18:35He's trying to bite this one.
0:18:35 > 0:18:38Are their teeth sharp enough to get into the coconut?
0:18:38 > 0:18:42Not at that size, but they can work their way into it.
0:18:42 > 0:18:45A big adult male like Spock can start cracking it,
0:18:45 > 0:18:49but not strong enough to bite through it and crack it open.
0:18:49 > 0:18:52- Where are these guys from?- India.
0:18:52 > 0:18:56And what about the tails? What is that used for? Balancing?
0:18:56 > 0:18:58They don't use them as much
0:18:58 > 0:19:02as you see a lot of the primates that live high up in the canopies do.
0:19:02 > 0:19:05But they still use them for balance.
0:19:05 > 0:19:09You can see him running along there. He's got into that one.
0:19:09 > 0:19:12Now he's charging around the enclosure with it.
0:19:12 > 0:19:16Is the idea to eat it high up to keep away from everyone else?
0:19:16 > 0:19:20He'll move around. They're following him because he's got into it.
0:19:20 > 0:19:24- "How have you done it, Boots?" - You can see them all doing that now.
0:19:24 > 0:19:28He's got right into that and he's probably eaten most of that coconut.
0:19:28 > 0:19:32Well done, Boots. He's the first one to crack the coconut.
0:19:32 > 0:19:35- He's the champion. - Liam, thank you so much.- No problem.
0:19:35 > 0:19:38They're all fighting for it now!
0:19:41 > 0:19:43# Boo boo ba ba boo...
0:19:44 > 0:19:48# Ba ba boo boo boo Ba ba boo... #
0:19:48 > 0:19:51It's Ask The Keeper time once again
0:19:51 > 0:19:55and today, we'll be learning all about those lovely lemurs.
0:19:55 > 0:19:58To help me out, I've got four inquisitive young minds.
0:19:58 > 0:20:03The keeper is Adam May who is a bit of a pro when it comes to primates.
0:20:03 > 0:20:06- Are you enjoying the weather? - Yeah, it's beautiful.
0:20:06 > 0:20:11Get ready for a storm of questions. Girls, bring on the thunder.
0:20:11 > 0:20:15- Are they born with black and white tails?- That's a very good question.
0:20:15 > 0:20:19We haven't bred the lemurs since I've been working here,
0:20:19 > 0:20:21so I've never actually seen a baby.
0:20:21 > 0:20:24But I presume they do because we've got a few here
0:20:24 > 0:20:28that have banding on their tails and there's some that don't.
0:20:28 > 0:20:32I presume some of them will be born with it and some without,
0:20:32 > 0:20:34but I'm not entirely sure about it.
0:20:34 > 0:20:36Why are their eyes so big?
0:20:36 > 0:20:40Their eyes are quite large, they're bright and very big
0:20:40 > 0:20:44because these guys are classed as cathemeral,
0:20:44 > 0:20:47so they're active during the day and night.
0:20:47 > 0:20:50Because they're active when there's low light levels,
0:20:50 > 0:20:54they need to have big eyes, so they can see well, much like cats' eyes.
0:20:54 > 0:20:58When you see a cat's eyes in the dark, they glow bright.
0:20:58 > 0:21:02It's one of the reasons why they're called lemurs. It means "ghost".
0:21:02 > 0:21:05Because people see the eyes and hear the loud shrieks,
0:21:05 > 0:21:09when it's dark, they said they were like ghosts.
0:21:09 > 0:21:13- Do you have to cut their fingernails? - No, with these guys, we don't.
0:21:13 > 0:21:17I don't know if we can see. It's a bit difficult.
0:21:17 > 0:21:20They have what's called a grooming claw on their toe
0:21:20 > 0:21:22which is next to the thumb.
0:21:22 > 0:21:25Next to the big toe. That's a bit longer.
0:21:25 > 0:21:29That's the grooming claw used for cleaning themselves and each other.
0:21:29 > 0:21:32But they have fingernails like us.
0:21:32 > 0:21:35They tend to wear them down as they run around,
0:21:35 > 0:21:37so we don't worry about their nails.
0:21:37 > 0:21:42- Any other questions?- How can they communicate with other animals?
0:21:42 > 0:21:46Yeah, communication with these guys is mainly vocal,
0:21:46 > 0:21:50so they do a lot of different calls like we would speak.
0:21:50 > 0:21:54They do a very loud alarm call. It's like a barking, like a dog.
0:21:54 > 0:21:59It sounds like they're aggressive, but they're not angry or anything.
0:21:59 > 0:22:04Can you communicate with these guys? Have you learnt any of their sounds?
0:22:04 > 0:22:08I can tell what they mean, but there's a lot we're not too sure of.
0:22:08 > 0:22:12Sometimes it's difficult to understand why they do it.
0:22:12 > 0:22:16- Adam, I am pretty impressed with your knowledge so far.- Thank you.
0:22:16 > 0:22:21Will your lemur luck run out now as it's time for the killer question?
0:22:21 > 0:22:23WHISPERING
0:22:23 > 0:22:28OK, of the questions so far, he's answered every single one right.
0:22:28 > 0:22:33- That's a good one. OK, Adam, I think we've got you.- OK.- Are you ready?
0:22:33 > 0:22:35Yeah, go ahead.
0:22:35 > 0:22:39How many teeth in total does a lemur have?
0:22:39 > 0:22:41Oh, that's a good one.
0:22:41 > 0:22:45That's a very good question. I'm not sure about that one.
0:22:45 > 0:22:48They have incisors like we do
0:22:48 > 0:22:51and canines and a few molars at the back.
0:22:51 > 0:22:54I think it's about 26 that they have,
0:22:54 > 0:22:59but I'm not too sure about that one, so I think you've got me that time.
0:22:59 > 0:23:03- It's quite a good guess, but you're ten off.- Ten off?- Yeah.
0:23:03 > 0:23:07Lemurs actually have 36 teeth, so we got you on that one.
0:23:07 > 0:23:11- You got me on that one, yeah. - You did pretty well.
0:23:11 > 0:23:15Girls, overall, how do you reckon Adam did? Thumbs up or thumbs down?
0:23:15 > 0:23:17Thumbs up all round.
0:23:17 > 0:23:21You didn't get the killer question right, but you did pretty well.
0:23:21 > 0:23:25Find out how our next keeper gets on in Ask The Keeper.
0:23:31 > 0:23:35Over at the hunting dog enclosure, the keepers are preparing
0:23:35 > 0:23:39to let brothers Dead Eye Dave and Chobe back in together.
0:23:40 > 0:23:43Dave has recovered well from his operation,
0:23:43 > 0:23:46but his biggest hurdle may still lie ahead
0:23:46 > 0:23:50because African hunting dogs are very aggressive.
0:23:50 > 0:23:54Chobe may not want his brother back and could go in for the kill,
0:23:54 > 0:23:57so we were asked to keep well back
0:23:57 > 0:24:01and the keepers let them meet again through a fence.
0:24:01 > 0:24:06When they didn't snarl, Rich took the chance of opening the slide.
0:24:07 > 0:24:10Good boy. Go on then. Good lad.
0:24:14 > 0:24:16Good boys.
0:24:17 > 0:24:19You be nice to him.
0:24:19 > 0:24:24To everyone's relief, they greeted each other like...well, brothers.
0:24:24 > 0:24:27We left them overnight to settle down.
0:24:27 > 0:24:32- Now Chris Hales has come to bring them a treat.- Come on, you two.
0:24:36 > 0:24:40Obviously, yesterday, poor old Dead Eye Dave had his eye taken out.
0:24:40 > 0:24:43If any human being had had that done to them,
0:24:43 > 0:24:49I'm sure we'd still be laying in a hospital complaining of lots of pain,
0:24:49 > 0:24:52whereas he's running around with his brother there.
0:24:52 > 0:24:56He's acting as if nothing's happened whatsoever.
0:24:56 > 0:25:00It's fantastic. It goes to show just how tough African wild dogs are.
0:25:09 > 0:25:13Well, unfortunately, it's nearly time for the end of the show.
0:25:13 > 0:25:17It is, but how could we leave you without a bit of "fowl" play first?
0:25:17 > 0:25:21I'm not talking about the way Johny plays footie, but guinea fowl.
0:25:21 > 0:25:25- We're here with keeper Barry. How are you?- Fine, Johny.
0:25:25 > 0:25:29- Nice to see you, Barry.- Ten guinea fowl chicks. They are adorable.
0:25:29 > 0:25:32- What's this?- This is their food. They eat chick mash.
0:25:32 > 0:25:35What's in there? Seeds and things like that?
0:25:35 > 0:25:39- Yeah, it's all mashed up nice and small.- That's a lot.
0:25:39 > 0:25:42There are ten of them and they do go through it.
0:25:42 > 0:25:46- Let's place it down.- They won't come straight over because we're in here.
0:25:46 > 0:25:50They keep together as a gang. We'll be as calm and gentle as possible.
0:25:50 > 0:25:53- Will they always stick together? - We hope so.
0:25:53 > 0:25:58We've got five in the main paddock and they're fully-grown adults.
0:25:58 > 0:26:01They hang about together. It's quite cute.
0:26:01 > 0:26:05- Are they all healthy and well? - Yeah, we are delighted with them.
0:26:05 > 0:26:10When you come to a park like this, we see the ellies, lions and tigers.
0:26:10 > 0:26:13What do the guinea fowl add to the deer park?
0:26:13 > 0:26:16It's interesting. People come to the deer park
0:26:16 > 0:26:19and when they see a flock of guinea fowl,
0:26:19 > 0:26:21they go, "What on earth are they?"
0:26:21 > 0:26:25They're quite funny and they're obviously quite noisy.
0:26:25 > 0:26:28They're just fun to have around.
0:26:28 > 0:26:32We don't want to stress them out. It's been fantastic to get so close.
0:26:32 > 0:26:34I think we should fly the nest.
0:26:34 > 0:26:38Yeah, and while we do, check out what's on the next episode of Roar.
0:26:38 > 0:26:42- You didn't laugh. I said "fly the nest".- Ah!
0:26:44 > 0:26:49'There's been a very rare sighting out in the safari area -
0:26:49 > 0:26:52'a new-born baby antelope and it's pure white,
0:26:52 > 0:26:55'but could its colour be the death of it?
0:26:56 > 0:27:01'The fishing cat gets crabby, but who's got the sharpest claws?
0:27:01 > 0:27:05'And I try to make friends with the silverbacks...
0:27:05 > 0:27:07'without much success.'
0:27:07 > 0:27:10Was that telling us off or telling Boo Boo off?
0:27:10 > 0:27:14- I think it's telling you guys off. - Right, OK.
0:27:14 > 0:27:17'Make sure you're watching.'
