0:00:02 > 0:00:04It's yet another exclusive for Roar -
0:00:04 > 0:00:07we're bringing you the first ever pictures
0:00:07 > 0:00:09of a brand new baby gorilla.
0:00:09 > 0:00:12And they don't come any cuter than this.
0:00:36 > 0:00:40- Hello and welcome to Roar, I'm Johny...- And I'm Rani.
0:00:40 > 0:00:44Let us introduce you to the breathtaking gelada baboons.
0:00:44 > 0:00:46Now this species are the most peaceful
0:00:46 > 0:00:48and least aggressive of all baboons.
0:00:48 > 0:00:51They spend most of their time foraging for food.
0:00:51 > 0:00:54And when it comes to food, these guys definitely like their greens,
0:00:54 > 0:00:56they're partial to a blade of grass.
0:00:56 > 0:01:00That's right, during the wet season, when the grass is greener,
0:01:00 > 0:01:02it makes a whopping 93% of their diet!
0:01:02 > 0:01:03Euch!
0:01:03 > 0:01:04I said THEIR diet.
0:01:04 > 0:01:05Thanks, guys.
0:01:05 > 0:01:09While Johny tries out his new diet, here's what's coming up...
0:01:10 > 0:01:14There's a new tamarin in town, but will the other monkeys welcome her,
0:01:14 > 0:01:16or drive her out?
0:01:16 > 0:01:18Slightly nervous about the whole ordeal,
0:01:18 > 0:01:20we only have one group of tamarins,
0:01:20 > 0:01:24so we don't have an awful lot of experience with mixing groups.
0:01:24 > 0:01:27Tamarins, although they're small, they can be ferocious.
0:01:27 > 0:01:29We all know that lions are fierce,
0:01:29 > 0:01:33but we find out how incredibly strong they are too.
0:01:33 > 0:01:36- Oh, it's going. - It is going, isn't it?
0:01:36 > 0:01:39- The chord? - Yeah, she's destroying it.
0:01:39 > 0:01:43And the head keeper finds himself tied up in knots
0:01:43 > 0:01:45on Ask The Keeper.
0:01:45 > 0:01:46Do you know it's name...
0:01:46 > 0:01:47in Latin?
0:01:47 > 0:01:50Um... Ah!
0:01:53 > 0:01:54But first...
0:01:54 > 0:01:56it's a big day down at the tamarin house -
0:01:56 > 0:02:00a new breeding female has arrived from another collection,
0:02:00 > 0:02:02but how will the rest react?
0:02:02 > 0:02:06No-one can be sure whether they'll be nice to her,
0:02:06 > 0:02:08or very, VERY nasty.
0:02:09 > 0:02:11Red bellied tamarins are small primates
0:02:11 > 0:02:15who live high up in the canopy of the Western Amazon Rainforest
0:02:15 > 0:02:17in South America.
0:02:17 > 0:02:19The family here have had babies before,
0:02:19 > 0:02:21but head of section, Matt Ford,
0:02:21 > 0:02:25tells us that, sadly, the mum died during the winter.
0:02:25 > 0:02:30Currently, we have got the adult male left and his son and his daughter.
0:02:30 > 0:02:33The dad is seven years old, the boy is now three
0:02:33 > 0:02:38and the little girl's is only one. They clearly need an adult female,
0:02:38 > 0:02:41a new mum, if there are to be any more babies.
0:02:41 > 0:02:45But how will the family feel about the newcomer?
0:02:45 > 0:02:47The problem I can foresee is with the females.
0:02:47 > 0:02:51We're bringing in an adult female, completely unrelated to our group,
0:02:51 > 0:02:54and she'll want to be dominant, basically.
0:02:54 > 0:02:56Whilst the daughter is still quite young,
0:02:56 > 0:02:59she has been the only female in the group for a while now,
0:02:59 > 0:03:01and might want to keep it that way.
0:03:01 > 0:03:04But she'll be up against a new female
0:03:04 > 0:03:07who is older, bigger and stronger than her.
0:03:07 > 0:03:09Slightly nervous about the whole ordeal,
0:03:09 > 0:03:11we only have one group of tamarins,
0:03:11 > 0:03:14we don't have a lot of experience mixing groups.
0:03:14 > 0:03:16Our pair came established when we got them,
0:03:16 > 0:03:18this is a very new thing for us.
0:03:18 > 0:03:19I am hoping that it goes OK.
0:03:19 > 0:03:23Tamarins, although they're small, they can be ferocious
0:03:23 > 0:03:25and could do a lot of damage to each other.
0:03:25 > 0:03:27I don't want our resident female to be injured,
0:03:27 > 0:03:30so we'll have to see how far we can leave it
0:03:30 > 0:03:32before we might have to separate them off if it goes bad.
0:03:32 > 0:03:36Matt's decided to mix the monkeys in three stages.
0:03:36 > 0:03:40First, the daughter is going to meet the new female all on her own,
0:03:40 > 0:03:44so the keepers only have two to deal with if the meeting goes badly.
0:03:44 > 0:03:48So, will they be friends or fight to the death?
0:03:48 > 0:03:50No-one knows.
0:03:50 > 0:03:54The new girl's in the outer enclosure,
0:03:54 > 0:03:56this is the big moment.
0:03:56 > 0:03:58How will they react?
0:03:58 > 0:04:02They open the slide and the daughter comes straight through.
0:04:10 > 0:04:14They don't go for one another and Matt's delighted.
0:04:14 > 0:04:18The behaviours that we've seen are very, sort of, subdued.
0:04:18 > 0:04:22The female from our existing group is scent marking, um...
0:04:22 > 0:04:25and the new female's going over and scent marking.
0:04:25 > 0:04:30That's basically saying that they're both happy with the territory,
0:04:30 > 0:04:34and they're not getting aggressive. HIGH-PITCHED SQUEAKING
0:04:34 > 0:04:37The high-pitched noise they're making is a friendly vocalization,
0:04:37 > 0:04:42nothing aggressive, and they're following each other around
0:04:42 > 0:04:43which is good.
0:04:44 > 0:04:47So, the first introduction has gone well
0:04:47 > 0:04:49and Matt can now move on to stage two -
0:04:49 > 0:04:51bringing in the boys.
0:04:51 > 0:04:55We'll come back shortly to see if that goes peacefully.
0:05:06 > 0:05:08Layla and Jabir, the park's Barbary lions,
0:05:08 > 0:05:10are used to getting their own way.
0:05:10 > 0:05:12But not today, folks, because keepers Chris and Jess
0:05:12 > 0:05:15have come up with a way of making these lairy lions
0:05:15 > 0:05:16work for their food.
0:05:16 > 0:05:18- Isn't that right, guys?- It is.
0:05:18 > 0:05:21How you doing? So, what is this contraption, then?
0:05:21 > 0:05:24This is a pulley feeding device, that's what we've called it.
0:05:24 > 0:05:28Um, but basically, inside this tube, here, is a garage-door spring,
0:05:28 > 0:05:30a very sturdy thing and...
0:05:30 > 0:05:33Well, we've both tried to pull it as hard as we can
0:05:33 > 0:05:35and we can't budge it at all.
0:05:35 > 0:05:38So these guys might pull this out to get the meat?
0:05:38 > 0:05:41Well hopefully not. What we're hoping is that they can pull it
0:05:41 > 0:05:43and get a little bit of give on the spring,
0:05:43 > 0:05:46but not so much that the spring ends up in a straight line.
0:05:46 > 0:05:49- OK.- OK? The idea is they pull on it and get resistance,
0:05:49 > 0:05:52so it feels like the food's fighting back as it would do
0:05:52 > 0:05:54if they were taking down prey in the wild.
0:06:02 > 0:06:03When lions go in for the kill,
0:06:03 > 0:06:07they sink they're claws and powerful jaws into their prey,
0:06:07 > 0:06:11then use their enormously strong neck muscles to pull it down.
0:06:15 > 0:06:19'The keepers here have never tried to simulate that tussle before
0:06:19 > 0:06:23'and I think their contraption may be a bit puny.'
0:06:23 > 0:06:26Now, guys, you two have had a go at it,
0:06:26 > 0:06:29but I've got to say, I'm pretty strong, so let me have a go.
0:06:29 > 0:06:31I'll show you how it's done.
0:06:31 > 0:06:32Here we go!
0:06:32 > 0:06:35Have you got it that side? Have you got a good grasp on it?
0:06:35 > 0:06:37I'm holding it tight.
0:06:39 > 0:06:40Let me just do that again.
0:06:47 > 0:06:49It's definitely not going anywhere! Wow!
0:06:49 > 0:06:52It looks good, but where do you want to hang this up?
0:06:52 > 0:06:56We've got a couple of places around the enclosure we can hang it,
0:06:56 > 0:06:58but as I'm sure you really want to see what's going on,
0:06:58 > 0:07:00we're going to hang it over here.
0:07:00 > 0:07:03So, if you wan to help us out, Johny, and grab the rear...
0:07:03 > 0:07:05That's a heavy piece of meat, wow!
0:07:06 > 0:07:08I mean, would they come across...
0:07:08 > 0:07:11I guess they'd hunt big animals out in the wild,
0:07:11 > 0:07:15- would they be able to tackle this? - They're not due to be fed today,
0:07:15 > 0:07:17this is actually just a snack for them.
0:07:17 > 0:07:20Um... And so, because they do eat such huge pieces of food,
0:07:20 > 0:07:23we don't feed them every day, but we want to see if this works
0:07:23 > 0:07:25and so they got a little treat today.
0:07:25 > 0:07:27So, that's in position.
0:07:27 > 0:07:31- Will they know it's here? Will they come up, do you think?- Definitely.
0:07:31 > 0:07:34They know we're here, Layla's always watching us,
0:07:34 > 0:07:35she knows where the food is.
0:07:35 > 0:07:38Jabir's not so clever, he's always pacing, going,
0:07:38 > 0:07:41"Oh! Where is it?" And he comes out and he's like, "Oh."
0:07:41 > 0:07:44And by that time, Layla's cleared off with it, so...
0:07:44 > 0:07:47- He's not the brightest, is he?- Do you think they could fight over this?
0:07:47 > 0:07:52Possibly. Although, in theory, the male should really take the food,
0:07:52 > 0:07:55but Layla... She's actually quite a large female lion,
0:07:55 > 0:07:58and so she does hold her own when it comes to the feed.
0:07:58 > 0:08:01So, Jess, are you sure that this will...
0:08:01 > 0:08:02definitely stay put,
0:08:02 > 0:08:05are you sure that the lions won't be able to take it straight off?
0:08:05 > 0:08:06Who knows?
0:08:06 > 0:08:09This is the first time we've tried, so we don't know,
0:08:09 > 0:08:12- but hopefully, it will.- I can see the lions pacing back and forth
0:08:12 > 0:08:16and before they get any ideas about US being their food
0:08:16 > 0:08:19- I think we should get out, what do you reckon?- Good idea.
0:08:19 > 0:08:22And while we do, why don't you watch the rest of the show
0:08:22 > 0:08:23and join us later on to find out
0:08:23 > 0:08:26what these two lions make of our contraption.
0:08:32 > 0:08:35Where does a reindeer go if it looses its tail?
0:08:35 > 0:08:36I dunno.
0:08:36 > 0:08:38The retail shop.
0:08:40 > 0:08:42Woof, woof! Woof, woof!
0:08:43 > 0:08:46What do you get if you cross a sheep and a kangaroo?
0:08:46 > 0:08:48- I don't know.- A woolly jumper.
0:08:50 > 0:08:52SHE CHATTERS LIKE A MONKEY
0:08:54 > 0:08:57What happens when two giraffes collide?
0:08:57 > 0:08:58I don't know.
0:08:58 > 0:08:59A giraffic jam!
0:09:11 > 0:09:15We have a particularly brave group of Roar fans here today.
0:09:15 > 0:09:16Which is lucky,
0:09:16 > 0:09:20because they're about to face a pretty scary creature.
0:09:26 > 0:09:30It's Ask The Keeper time now here on Roar, and the keeper in question is,
0:09:30 > 0:09:34- head keeper actually, Rich Barnes! Hiya, Rich.- Hello.
0:09:34 > 0:09:36Now this lot, they're very clever, they are,
0:09:36 > 0:09:39and they have got some great questions for you.
0:09:39 > 0:09:43- But the question from me is - are you feeling confident?- Always.
0:09:43 > 0:09:45What have you got in your hand, first of all?
0:09:45 > 0:09:47OK, this is an indigo snake.
0:09:47 > 0:09:49His name's Indy, nice and original.
0:09:49 > 0:09:50So, who wants to start us off?
0:09:50 > 0:09:52Go on then, Georgia.
0:09:52 > 0:09:53Does it live in trees?
0:09:53 > 0:09:56Good question. Well, because snakes don't have legs,
0:09:56 > 0:09:59lots of people would assume that this would be a hindrance,
0:09:59 > 0:10:02something that would stop them getting around,
0:10:02 > 0:10:03but it doesn't
0:10:03 > 0:10:06and snakes pretty much inhabit every single conceivable place -
0:10:06 > 0:10:09up in trees, on the ground, in water...
0:10:09 > 0:10:13But this particular one stays on the ground for most of its time.
0:10:13 > 0:10:15- Um, can I touch it? - You can touch it, yeah.
0:10:16 > 0:10:22- It's really soft.- Yeah, it feels quite nice, doesn't it? - It's really warm, as well.- Warm?
0:10:22 > 0:10:25- Why's it warm?- Well, she's come out of quite a warm enclosure.
0:10:25 > 0:10:29Although it's not particularly warm now the sun's gone behind the cloud,
0:10:29 > 0:10:34as long as he stays on me, he'll take in warmth from me.
0:10:34 > 0:10:36Technically, they are ectothermic,
0:10:36 > 0:10:38which means they take their heat from surroundings,
0:10:38 > 0:10:41so if they're on a surface that's warm,
0:10:41 > 0:10:42they'll take that heat in as well.
0:10:42 > 0:10:45How do you know whether it's female or male?
0:10:45 > 0:10:47With some of the more primitive snakes,
0:10:47 > 0:10:50length of tail is a good indication,
0:10:50 > 0:10:52the number of scales on the tail.
0:10:52 > 0:10:55But also they have little vestigial legs on the back,
0:10:55 > 0:10:57which are the remains of prehistoric limbs.
0:10:57 > 0:11:00But on these ones, they don't have any of that,
0:11:00 > 0:11:01so the only way we can tell is that...
0:11:01 > 0:11:04You can see there's a slight difference
0:11:04 > 0:11:07in the way the scales go there? This is what we call the vent
0:11:07 > 0:11:10and down there is where the snake's sexual organs
0:11:10 > 0:11:12and where it goes to the toilet are.
0:11:12 > 0:11:16And basically, what we do is we get a probe, push it down here, and,
0:11:16 > 0:11:18depending on how deep it goes,
0:11:18 > 0:11:21determines whether it's a male or female.
0:11:21 > 0:11:24If it goes quite deep down, then it's a male.
0:11:24 > 0:11:26If it goes not so far down, it's a female. OK?
0:11:26 > 0:11:30Is it poisonous, and if it is, is it lethal enough to kill a man?
0:11:30 > 0:11:33I shouldn't be standing this close, then!
0:11:33 > 0:11:35There's a couple of points to that question.
0:11:35 > 0:11:38Firstly, there are no poisonous snakes in the world,
0:11:38 > 0:11:40they're all venomous, not poisonous.
0:11:40 > 0:11:42And the difference between a venom and a poison
0:11:42 > 0:11:44is that a venom has to go into your bloodstream,
0:11:44 > 0:11:46whereas a poison can be ingested,
0:11:46 > 0:11:49taken in through the mouth or the skin or a number of ways.
0:11:49 > 0:11:52So, firstly, no, he's non-venomous,
0:11:52 > 0:11:55but he does have a couple of tricks up his sleeve.
0:11:55 > 0:11:57That is, he's part of the King Snake family,
0:11:57 > 0:12:01which means that part of his diet consists of other snakes
0:12:01 > 0:12:05and he's able to consume and to have immunisation from the venom
0:12:05 > 0:12:08of rattlesnakes and water mocassins and things like that.
0:12:08 > 0:12:11So he's able to not only defend against them,
0:12:11 > 0:12:13but also eat them, if he feels like it.
0:12:13 > 0:12:16- Does he have good eyesight? - Their eyesight is quite poor.
0:12:16 > 0:12:19There are a few snakes that have better eyesight,
0:12:19 > 0:12:22but this particular one would rely on its other senses, which are what?
0:12:22 > 0:12:24What do you think its senses are?
0:12:24 > 0:12:27- Smell.- Yep, smell. You can see his nostrils there.
0:12:27 > 0:12:28He's got no ears.
0:12:28 > 0:12:30He's doing something now which is quite obvious.
0:12:30 > 0:12:33- Is it his tongue?- It's his tongue. That's his main sense,
0:12:33 > 0:12:35and he'll rely on that most of all
0:12:35 > 0:12:37and that will help him find all his food,
0:12:37 > 0:12:40find his way about, find other snakes.
0:12:40 > 0:12:42Rich, so far you're doing really well.
0:12:42 > 0:12:45In fact, you're doing extremely well.
0:12:45 > 0:12:48We need to catch you out. Guys, huddle up, shall we?
0:12:48 > 0:12:50Let's come up with a killer question for him.
0:12:50 > 0:12:52THEY CONFER
0:12:54 > 0:12:57Shall I ask that one? All right, brilliant.
0:12:57 > 0:13:03- You should look worried, Rich Barnes.- I am worried, yes.
0:13:03 > 0:13:05What have you conjured up?
0:13:05 > 0:13:07We've had a think and here is our question for you.
0:13:07 > 0:13:12The indigo snake, do you know its name...in Latin?
0:13:12 > 0:13:13Uhh...
0:13:13 > 0:13:17Ohh... I should know this!
0:13:17 > 0:13:20You SHOULD know this, head keeper Rich Barnes!
0:13:20 > 0:13:24I can't... It's not in my head at the moment, no. Go on, then.
0:13:24 > 0:13:27- Drymarchon Corais. - Drymarchon, that's it.
0:13:27 > 0:13:31Well done, us, we caught Rich Barnes out with a killer question!
0:13:31 > 0:13:36So, apart from not knowing the Latin name for the indigo snake...
0:13:36 > 0:13:38I just misplaced it in my brain today.
0:13:38 > 0:13:39Yeah, we believe you(!)
0:13:39 > 0:13:43I've had a very hard intellectual day, I'll have you know, so...
0:13:43 > 0:13:46Yes, OK. What do you think, then, for Rich - thumbs up or thumbs down?
0:13:47 > 0:13:50Oh, Cain's giving you grief over there!
0:13:50 > 0:13:53One thumb sideways! You know what, Rich? I think you did all right.
0:13:53 > 0:13:56- Just work on your Latin. - Yeah, all right.
0:13:56 > 0:13:59OK, Make sure you join us next time on Roar for more Ask The Keeper.
0:14:05 > 0:14:07Earlier on, the new adult female tamarin,
0:14:07 > 0:14:10who's been brought in to help start a new family,
0:14:10 > 0:14:15was introduced to the young female here. Fortunately, it didn't fight.
0:14:17 > 0:14:20Now it's time for stage two, bringing in the two males,
0:14:20 > 0:14:22who might be much fiercer.
0:14:22 > 0:14:24They show no sign of leaving the back room though,
0:14:24 > 0:14:26so the little girl goes in to get them.
0:14:30 > 0:14:34Suddenly, the enclosure's full of monkeys rushing all over the place.
0:14:43 > 0:14:46The good news is that none of them are fighting with the new female,
0:14:46 > 0:14:50and Matt think's that we may have something to do with that.
0:14:50 > 0:14:53Having yourselves here and me and my fellow keeper in the shed
0:14:53 > 0:14:56has actually helped because it's distracted them a bit
0:14:56 > 0:15:00from the actual situation. We'll just have to hope that when we leave,
0:15:00 > 0:15:03it won't go into fights and things like that.
0:15:04 > 0:15:06Just in case it does,
0:15:06 > 0:15:09we have a camera rigged up to record stage three.
0:15:09 > 0:15:11What happens when we've all left?
0:15:11 > 0:15:15We'll come back later to find out whether the new female
0:15:15 > 0:15:17has been accepted by the other tamarins.
0:15:17 > 0:15:19Or not.
0:15:25 > 0:15:28Earlier, we set up a feeding contraption
0:15:28 > 0:15:31to test out the Barbary lion's strength.
0:15:31 > 0:15:34I'm here with keeper Jess and keeper Chris, who's just over there,
0:15:34 > 0:15:36and he's ready to release the lions on your word.
0:15:36 > 0:15:38I'm ready when you are.
0:15:38 > 0:15:41Chris, come on then!
0:15:41 > 0:15:43Let them out! Release the beasts!
0:15:47 > 0:15:49Out they come. Who's come out first?
0:15:49 > 0:15:52This is Layla, the one we thought would be first on the meat.
0:15:52 > 0:15:54Right, Layla's the female.
0:15:54 > 0:15:55Oh, she's tried to take it away.
0:15:55 > 0:15:59Do you think they'll get angry at not being able to grab the meat
0:15:59 > 0:16:00and take it where they want?
0:16:00 > 0:16:02No, I think it'll just make them work for it,
0:16:02 > 0:16:04that's what we want them to do.
0:16:04 > 0:16:06Layla would usually grab the meat and run
0:16:06 > 0:16:09because she doesn't want Jabir to get it.
0:16:09 > 0:16:10Obviously now she can't.
0:16:10 > 0:16:13So she's doing what we thought she'd do and eat it there.
0:16:13 > 0:16:15That meat is just there waiting
0:16:15 > 0:16:18and I'm surprised Jabir hasn't challenged her for it. Why's that?
0:16:18 > 0:16:22Generally, when we feed these guys, you put a couple of pieces out.
0:16:22 > 0:16:24She is always the first to the food
0:16:24 > 0:16:27and he spends ages trying to find the other piece.
0:16:27 > 0:16:30He probably thinks there's another piece out here.
0:16:30 > 0:16:32Look at this, we've seen her strength now.
0:16:32 > 0:16:35She's given it a right old tug. It's holding up so far.
0:16:35 > 0:16:38She's not really doing what we were hoping, though.
0:16:38 > 0:16:40What were you hoping?
0:16:40 > 0:16:42We were hoping she would be...
0:16:42 > 0:16:43Doing that!
0:16:45 > 0:16:48You can see, actually, it's going.
0:16:48 > 0:16:50That is amazing, look at the strength!
0:16:50 > 0:16:52We've all had a go at that. Look at this!
0:16:52 > 0:16:54She's actually pulling it away!
0:16:54 > 0:16:55Don't destroy...
0:16:55 > 0:16:57That's amazing!
0:16:57 > 0:16:59I cannot believe what I'm seeing.
0:17:01 > 0:17:02- It's going.- It is going, isn't it?
0:17:02 > 0:17:05- DO you think it's going to go? - Yeah, she's destroying it.
0:17:05 > 0:17:07Could the string bounce and hurt her?
0:17:07 > 0:17:10Other places have had this kind of issue
0:17:10 > 0:17:13and all that's happened is that the string has ended up
0:17:13 > 0:17:15as a straight piece of metal.
0:17:15 > 0:17:19That was an amazing display of strength.
0:17:19 > 0:17:23Jabir is very clever. Is he trying bite the top of it to release it?
0:17:23 > 0:17:25Actually, he's not very clever!
0:17:25 > 0:17:27(THEY LAUGH)
0:17:27 > 0:17:29You're right, he is trying to bite the top of it,
0:17:29 > 0:17:31but we're not entirely sure why. It's not food.
0:17:31 > 0:17:35Probably because he doesn't want to go near Layla and still wants food!
0:17:35 > 0:17:39What would happen if he went over and tried to get the meat from her?
0:17:39 > 0:17:42We've had situations in the past where he's tried to do that
0:17:42 > 0:17:44and he hasn't tried again since.
0:17:44 > 0:17:47He's got a few scars on his nose and they're all from her.
0:17:47 > 0:17:51We've been testing out their strenth today and they are very powerful,
0:17:51 > 0:17:53but why do they need to be so strong?
0:17:53 > 0:17:54They are naturally strong.
0:17:54 > 0:17:57In the wild, they'd use their muscles to pull down their prey,
0:17:57 > 0:17:58pull it to the floor.
0:17:58 > 0:18:00Being here, they don't get that.
0:18:00 > 0:18:03That's why we try and think of as many ways as possible
0:18:03 > 0:18:06to stimulate them like they would be in the wild.
0:18:06 > 0:18:08If we hang that higher up, she'll have to pull it
0:18:08 > 0:18:11and she'll be using the same muscles she would
0:18:11 > 0:18:13to pull down natural prey in the wild.
0:18:13 > 0:18:15Look at this, this is hilarious.
0:18:15 > 0:18:16Jabir has just laid down
0:18:16 > 0:18:21and is he waiting for Layla to finish and then he'll have his food?
0:18:21 > 0:18:22They've actually swapped roles.
0:18:22 > 0:18:26Normally the male would eat the food and the female would be next door.
0:18:26 > 0:18:27Complete role reversal.
0:18:27 > 0:18:30That's funny! Do you think Layla will know to save him some?
0:18:30 > 0:18:33Definitely not. Layla will eat as much as she can get.
0:18:33 > 0:18:37They're both quite big at the moment because they eat as much as they can.
0:18:37 > 0:18:39She won't save any for Jabir if she can help it.
0:18:39 > 0:18:41Will you use this again, Chris?
0:18:41 > 0:18:42Yeah, definitely.
0:18:42 > 0:18:44We put it down lower this time
0:18:44 > 0:18:47just because it's the first time we've used it.
0:18:47 > 0:18:50But we'll put it up higher next time so the entire meat's hanging down,
0:18:50 > 0:18:54in which case she will be pulling on it to get it onto the ground.
0:18:54 > 0:18:57Next time you should put two in because poor Jabir, look at him!
0:18:57 > 0:19:00He's just waiting for his feed.
0:19:00 > 0:19:03I tell you what, while she enjoys her food,
0:19:03 > 0:19:06I think I'm going to get out of here and leave you two guys
0:19:06 > 0:19:09to go in there afterwards and get your device back.
0:19:09 > 0:19:10Good luck.
0:19:16 > 0:19:20It's always fun to see the young gorillas playing around,
0:19:20 > 0:19:23because, well, they're just adorable.
0:19:23 > 0:19:27And there are more of them than ever at the moment,
0:19:27 > 0:19:29because four have been born here this year alone.
0:19:31 > 0:19:35In the last Roar, we met a delightful youngster
0:19:35 > 0:19:37who was just two months old.
0:19:40 > 0:19:43But today we're going to meet an even younger one,
0:19:43 > 0:19:47who's barely two weeks old, for the very first time.
0:19:49 > 0:19:52This is the largest gorilla enclosure in the world,
0:19:52 > 0:19:56which is just as well, as there's a family of 15 living here.
0:19:56 > 0:19:58No, sorry - make that 16 now,
0:19:58 > 0:20:03because of Daddy and Mummy's latest pride and joy.
0:20:03 > 0:20:08Head of section Phil has invited us to meet the new arrival.
0:20:08 > 0:20:10So far, mum and baby are doing really well,
0:20:10 > 0:20:11healthy and happy.
0:20:11 > 0:20:15Just like a human mum, she was pregnant for nine months
0:20:15 > 0:20:19before having the baby in the small hours of the morning.
0:20:19 > 0:20:21We didn't see the birth - day she didn't have the baby,
0:20:21 > 0:20:23and the following morning she did.
0:20:23 > 0:20:25She gave birth during the night, no-one saw it.
0:20:25 > 0:20:29The new-born baby only weighed two kilos,
0:20:29 > 0:20:31that's about five cans of baked beans.
0:20:31 > 0:20:33But just two weeks later,
0:20:33 > 0:20:37the tiny gorilla is already beginning to blossom.
0:20:37 > 0:20:39We can see that the baby is gripping on well,
0:20:39 > 0:20:42and that's mum's coping OK with the added responsibility
0:20:42 > 0:20:44of holding baby and moving around.
0:20:44 > 0:20:49But is mum cuddling a little son or a daughter?
0:20:49 > 0:20:54Mum is keeping that a secret because she's very camera-shy.
0:20:54 > 0:20:56We don't know what sex it is yet,
0:20:56 > 0:21:00we haven't been able to see the relevant parts of its anatomy,
0:21:00 > 0:21:03cos mum's been holding the baby in so tight and close.
0:21:03 > 0:21:05She's been very protective.
0:21:05 > 0:21:08The baby will need to be quite a lot bigger
0:21:08 > 0:21:10before mum will let it go and play
0:21:10 > 0:21:12with its boisterous brothers and sisters,
0:21:12 > 0:21:14as sometimes they can go too far.
0:21:14 > 0:21:18Growing up as a gorilla can be a pretty hard life,
0:21:18 > 0:21:21they have to learn pretty quick how to duck and weave.
0:21:21 > 0:21:23They get the odd knock and bite.
0:21:23 > 0:21:26That's all in the future, but for the moment,
0:21:26 > 0:21:30this little baby is just happy, healthy and simply adorable.
0:21:30 > 0:21:34Exciting times ahead, and hopefully it will all go well.
0:21:34 > 0:21:39We'll be sure to bring you more news on the Gorilla House
0:21:39 > 0:21:41as the baby grows up.
0:21:42 > 0:21:47Stand by, Roar gamers, because it's time to give you today's cheat code.
0:21:47 > 0:21:52grass2 is all you need to type in to your online game
0:21:52 > 0:21:55to get treats and food for your animals.
0:21:55 > 0:21:58And don't forget to check out our exciting new enclosure,
0:21:58 > 0:22:02where you can look after animals from the british countryside.
0:22:09 > 0:22:10Back in the tamarind enclosure,
0:22:10 > 0:22:13our secret camera has been running for a couple of hours now,
0:22:13 > 0:22:17to see how the family would get on with the new adult female.
0:22:17 > 0:22:21Keeper Matt was worried that a fight might break out.
0:22:21 > 0:22:25Because we were around while the introduction was taking place,
0:22:25 > 0:22:30we put a camera in to shoot footage of the group when we had left.
0:22:30 > 0:22:35We've now watched the footage and it's very interesting to watch.
0:22:41 > 0:22:44The tamarind here is the daughter,
0:22:44 > 0:22:46the female in the doorway is the new girl.
0:22:46 > 0:22:51Right about now they nearly get into a bit of a scrap.
0:22:51 > 0:22:54The existing female chases her about
0:22:54 > 0:22:56and then goes back to the rest of the group.
0:22:56 > 0:22:59This is a stressful situation for the new one.
0:22:59 > 0:23:02It's the young female that's doing all the chasing,
0:23:02 > 0:23:04which we expected.
0:23:04 > 0:23:07She's protecting the group, basically,
0:23:07 > 0:23:10cos the females are quite aggressive.
0:23:10 > 0:23:12She's just chasing her around saying,
0:23:12 > 0:23:16"I'm the female here, you're not meant to be here."
0:23:16 > 0:23:19So, the young daughter is winning the battle for dominance,
0:23:19 > 0:23:22But the whole point of introducing the adult female
0:23:22 > 0:23:25was to establish a new breeding group.
0:23:25 > 0:23:27The adult male has bred well in the past,
0:23:27 > 0:23:29but if he's going to have any more children
0:23:29 > 0:23:32he needs the new female to come out on top.
0:23:32 > 0:23:35For the moment, though, he's keeping out of it.
0:23:35 > 0:23:41From the footage, the two males don't seem to want to be involved in it.
0:23:41 > 0:23:43They seem to be staying in the back rooms
0:23:43 > 0:23:46and the young female keeps coming out
0:23:46 > 0:23:48and being quite aggressive.
0:23:48 > 0:23:52But the two males are kind of being wooses.
0:23:54 > 0:23:56Eventually the dad does come out
0:23:56 > 0:23:59and asserts his position as the dominant male.
0:23:59 > 0:24:03The existing male actually comes head to head with the new female,
0:24:03 > 0:24:06they actually freak out a little bit, scream at each other.
0:24:06 > 0:24:08Although he is the dominant male of the group,
0:24:08 > 0:24:10he is nervous of the new arrival.
0:24:15 > 0:24:19Right, we've just gone on a few more minutes and this bit's interesting.
0:24:19 > 0:24:23The new female chases some of the group members away.
0:24:23 > 0:24:27So she's obviously getting a bit more confident with the situation.
0:24:27 > 0:24:30She's suddenly realising, "Hey, I'm the bigger animal.
0:24:30 > 0:24:32"I'm not going to be pushed around by this young female."
0:24:32 > 0:24:35So it really shows that she's a strong female.
0:24:35 > 0:24:40She'll be a good breeding female, she will be able to control the group.
0:24:40 > 0:24:42We're very positive of the outcome now
0:24:42 > 0:24:45and hopefully we will breed them again
0:24:45 > 0:24:49and the group will become as a family group should be.
0:24:49 > 0:24:52We'll come back later in the series
0:24:52 > 0:24:55to see if the red-bellied tamarinds do all settle down
0:24:55 > 0:24:58into one, big, happy family.
0:25:07 > 0:25:10Now we've nearly come to the end of the show
0:25:10 > 0:25:13but we've just got time to pop up to the safari area.
0:25:13 > 0:25:16If you've been watching in the last few days,
0:25:16 > 0:25:20you'll know that a new giraffe called Harris has joined the herd.
0:25:20 > 0:25:24So we've come out with Nick to see how Harris is getting on.
0:25:24 > 0:25:27He's doing really well. He was a bit nervous to begin with,
0:25:27 > 0:25:31nervous of the big space and all the other animals,
0:25:31 > 0:25:35- but he's settled in nicely. - You've got a rhino here as well,
0:25:35 > 0:25:38so, not nervous about the rhino at all?
0:25:38 > 0:25:41No, he's not. And the rhino's behaving himself, which is all good!
0:25:41 > 0:25:44I think the rhino wants some food as well.
0:25:44 > 0:25:47- Have the rest of the herd accepted him?- Yes, almost straight away
0:25:47 > 0:25:51- they were trying to get in with each other...- Oooh!- Ooops!
0:25:51 > 0:25:54Ooh, dear! Is he all right, Nick? Did he hurt his head?
0:25:54 > 0:25:58No, he's all right, he's OK. He'll come straight back for some food now.
0:25:58 > 0:26:03That's good. It's always expect the unexpected out here with the rhinos.
0:26:03 > 0:26:06- Yeah!- Harris is back, straight into the food.
0:26:06 > 0:26:10I'm presuming that he's got those horns to protect himself
0:26:10 > 0:26:12when things like that happen!
0:26:12 > 0:26:15Well, they are obviously for, sort of...
0:26:15 > 0:26:19fighting. When they're big adult males, they whack each other
0:26:19 > 0:26:23with those to try and sort of, you know,
0:26:23 > 0:26:25defend each other.
0:26:25 > 0:26:28Or possibly to fight over food!
0:26:28 > 0:26:31No, that's there for sort of defence against adult males
0:26:31 > 0:26:34when they're sparring each other.
0:26:34 > 0:26:38I can see they're all down for their food here. How is Harris coping
0:26:38 > 0:26:41with the rest of the group? Is he able to fight his corner
0:26:41 > 0:26:44to get enough food? Cos he is a bit smaller.
0:26:44 > 0:26:47He's been doing OK, yeah.
0:26:47 > 0:26:51The rhino's back again. Yeah, he's been doing OK.
0:26:51 > 0:26:53He gets his fair share.
0:26:53 > 0:26:57When we come out here in the tractor, we put an extra bucket of food out
0:26:57 > 0:27:01so that it spreads it out, the fight for food, a little bit more.
0:27:01 > 0:27:04He's certainly looking healthy, so is it all right if we stick around
0:27:04 > 0:27:08- and get to know him a bit better? - Yeah, no worries, no problem.
0:27:08 > 0:27:11And you can check out what's coming up on the next episode of Roar.
0:27:11 > 0:27:13Now, you watch your head!
0:27:15 > 0:27:21Brown hyenas are lean, mean and very rarely seen, even in the wild.
0:27:21 > 0:27:23The only ones in Britain are here in the park.
0:27:23 > 0:27:28And the keeper has to go in with them, despite the danger.
0:27:28 > 0:27:32And the biggest tigers in the world are hungry for red meat
0:27:32 > 0:27:33so we lay a trail for them.
0:27:33 > 0:27:36But will they be able to hunt down their dinner?
0:27:36 > 0:27:38Don't miss it!
