0:00:00 > 0:00:01with Kate Humble and Ben Fogle.
0:00:11 > 0:00:14Now, call me old-fashioned but I thought monogamy meant
0:00:14 > 0:00:17being with just one person at a time in a relationship.
0:00:17 > 0:00:22But that is not what's been going on here with the supposedly monogamous
0:00:22 > 0:00:23Humboldt penguins.
0:00:23 > 0:00:28No, I mean, Penguin Island is now Scandal Island rocked
0:00:28 > 0:00:29by a shocking love triangle.
0:00:29 > 0:00:31On today's programme,
0:00:31 > 0:00:35we're going to bring you all the gossip on Rihanna and Peaches
0:00:35 > 0:00:38as they vie for the attention of the ravishing Redley.
0:00:38 > 0:00:41But who will p-p-p-p-pick who?
0:00:41 > 0:00:44And more importantly, who's going to come out on top?
0:00:48 > 0:00:49Also in today's show,
0:00:49 > 0:00:55keeper Polly earns her stripes in Africa amongst some very rare zebra.
0:00:55 > 0:00:58Seeing them out here in the wild is amazing.
0:00:58 > 0:00:59It's, yeah, overwhelming!
0:01:02 > 0:01:05The park's gorillas give their verdict on a new diet.
0:01:05 > 0:01:08Both going for the tomatoes.
0:01:08 > 0:01:10Well, save some for the others, Evindi!
0:01:11 > 0:01:14There he is, that's it!
0:01:14 > 0:01:18And we'll reveal how an emu cools off in summer.
0:01:18 > 0:01:20When they're that hot and they need to cool down...
0:01:20 > 0:01:23Yeah, he's just sat himself for it, yeah! This is the best way for it.
0:01:32 > 0:01:34Now, to Penguin Island.
0:01:34 > 0:01:39Here, the girls outnumber the boys and it's causing problems.
0:01:39 > 0:01:43Penguins don't like being single, and the colony's unsettled.
0:01:43 > 0:01:47But things are about to change as some new boys are due to arrive
0:01:47 > 0:01:50on the island. And they are looking for love.
0:01:50 > 0:01:55Head of Animal Adventure, Graeme, hopes they'll be a big hit with his single ladies.
0:01:55 > 0:01:57My aim for the penguin colony is to stabilise it.
0:01:57 > 0:02:00That's my first goal.
0:02:00 > 0:02:01So what we're actually going to do
0:02:01 > 0:02:04is bring in slightly more male penguins than female penguins.
0:02:04 > 0:02:06And that allows a little bit of competition.
0:02:06 > 0:02:10It's a little bit of a dating game, and we'll see where we go.
0:02:10 > 0:02:14Lucy will be watching out to see if any sparks fly.
0:02:14 > 0:02:17You can never guess which penguin will fancy which penguin.
0:02:17 > 0:02:19Here we have Rihanna and Peaches.
0:02:19 > 0:02:22They are in a proper love triangle at the moment with Redley
0:02:22 > 0:02:24who has sat there all nonchalantly,
0:02:24 > 0:02:26pretending he's not caused any sort of drama.
0:02:27 > 0:02:30With the lack of male competition,
0:02:30 > 0:02:33Redley is getting away with being a bit of a rogue.
0:02:36 > 0:02:37It is a bit of a soap opera.
0:02:37 > 0:02:40I mean, he will quite happily cheat on his partners
0:02:40 > 0:02:42and flirt with any available females.
0:02:42 > 0:02:45So, it looks as if he might stick with Rihanna now.
0:02:45 > 0:02:47But I can never tell with him.
0:02:47 > 0:02:49So I make no promises.
0:02:49 > 0:02:52He may well go back to Peaches at a later date.
0:02:52 > 0:02:55So, it's whoever he chooses, really. And hopefully the other one will
0:02:55 > 0:02:57attach herself to one of our new boys.
0:02:59 > 0:03:03There have been several new arrivals in recent months
0:03:03 > 0:03:05following last winter's tragedy.
0:03:05 > 0:03:07Penguin Island became a ghost town
0:03:07 > 0:03:11after a disease and subsequent infections devastated the colony.
0:03:11 > 0:03:13Georgia was heartbroken.
0:03:13 > 0:03:16I have spent the last four years with the penguins,
0:03:16 > 0:03:18and they're like my children.
0:03:18 > 0:03:21People do say don't get too attached to animals.
0:03:21 > 0:03:24But when you're working with them every single day of the year,
0:03:24 > 0:03:26it's very hard not to.
0:03:28 > 0:03:32The deadly disease claimed the lives of 28 penguins,
0:03:32 > 0:03:34leaving just six survivors.
0:03:38 > 0:03:39Hi, Matt! Hi, Matt!
0:03:40 > 0:03:44It's almost midnight by the time the new penguins arrive.
0:03:44 > 0:03:48Kat and Georgia are there to welcome them.
0:03:48 > 0:03:51They've come from a collection in the Czech Republic and are part of
0:03:51 > 0:03:54the international breeding programme for Humboldt penguins.
0:03:55 > 0:03:58We're just going to put them in our hospital unit tonight,
0:03:58 > 0:04:00and then tomorrow we'll let them out
0:04:00 > 0:04:02into the exhibit to meet the other penguins.
0:04:02 > 0:04:04It's exciting having new penguins
0:04:04 > 0:04:08and especially to have some boys as well to mix it up a little bit.
0:04:08 > 0:04:10After losing so many birds,
0:04:10 > 0:04:14the arrival of every new penguin is a joy.
0:04:15 > 0:04:17Oh, there we go!
0:04:17 > 0:04:19Well done, sweetie!
0:04:19 > 0:04:22After last year and everything that we went through,
0:04:22 > 0:04:25we didn't think we'd be able to come out the other end happy.
0:04:25 > 0:04:29But, being able to just have the ability to bring new penguins in
0:04:29 > 0:04:32and start again, it's going to be really exciting.
0:04:32 > 0:04:34Hopefully, introducing the boys
0:04:34 > 0:04:37and then...we'll see some action pretty soon.
0:04:37 > 0:04:41So we'll come back tomorrow and see how they've done overnight.
0:04:44 > 0:04:46It's the morning after the night before.
0:04:46 > 0:04:49Merlin, Hugo, Maverick and Clive
0:04:49 > 0:04:52are about to get a first glimpse of their new home.
0:04:52 > 0:04:54So, should we let them out?
0:04:54 > 0:04:56Yep. Yeah?
0:05:03 > 0:05:04Here you go! Come on, then!
0:05:04 > 0:05:07Hey, guys! A little bit more nervous?
0:05:07 > 0:05:10They've been in a car for almost 24 hours,
0:05:10 > 0:05:12which for anyone is going to be stressful,
0:05:12 > 0:05:15let alone when they don't know what's happening.
0:05:15 > 0:05:18Redley's noseying. He's like, "What's going on?"
0:05:18 > 0:05:20Yeah, you're about get some new boys, mate.
0:05:20 > 0:05:23Oh, we'll see how they get on today.
0:05:23 > 0:05:25It'll be quite interesting.
0:05:25 > 0:05:28Because if they want a girlfriend or the girl wants that boyfriend,
0:05:28 > 0:05:33you know, they're going get it, whether it's over fighting or love.
0:05:33 > 0:05:35Penguins! Come on!
0:05:35 > 0:05:40Taking the first plunge in love, or indeed cold water, is never easy.
0:05:40 > 0:05:44So Lucy tries to tempt them towards the pool with some fish.
0:05:45 > 0:05:46Amazing.
0:05:46 > 0:05:47Clever boy!
0:05:49 > 0:05:52Maverick was born with a wing condition.
0:05:52 > 0:05:55It's quite noticeable as he's the one with only no bottom half
0:05:55 > 0:05:58of his wings. We're not going to discriminate, so we've taken him
0:05:58 > 0:06:01and hopefully he's a very friendly penguin.
0:06:01 > 0:06:04And also he's good at wooing the ladies.
0:06:04 > 0:06:07They've got very much a little pack mentality.
0:06:07 > 0:06:09So as soon as one jumps in the water,
0:06:09 > 0:06:11the others will follow straight away.
0:06:11 > 0:06:13All it will take is one to take the plunge
0:06:13 > 0:06:15and then all of them will follow.
0:06:19 > 0:06:21Yes!
0:06:21 > 0:06:23That's it, go on!
0:06:26 > 0:06:28Well done! Yes!
0:06:28 > 0:06:32Finally! Oh, they're in and that's all that matters.
0:06:32 > 0:06:35Our next hurdle will be introducing our original colony to them
0:06:35 > 0:06:37and seeing how they all get on with one another.
0:06:37 > 0:06:38So we just need to wait and see
0:06:38 > 0:06:41whether they take a liking to any of the girls, really.
0:06:41 > 0:06:46We'll be back later to find out if any of our penguins have found love.
0:06:54 > 0:06:59Caring for animals like giraffe and zebra is a year-round job
0:06:59 > 0:07:01every day, whatever the weather.
0:07:01 > 0:07:05And the keepers that look after their particular animals
0:07:05 > 0:07:08quickly become experts in those animals
0:07:08 > 0:07:10and what is best for their care.
0:07:10 > 0:07:13But of course the ultimate experience for these guys
0:07:13 > 0:07:17is seeing the animals they know so well here out in the wild.
0:07:19 > 0:07:22All of this week, we've been following five of the park's keepers
0:07:22 > 0:07:26visiting a project supported by British charity the Tusk Trust,
0:07:26 > 0:07:31as they carry out in-depth research to bring back to the park.
0:07:31 > 0:07:33Lewa Conservancy in northern Kenya
0:07:33 > 0:07:36leads the way in animal conservation,
0:07:36 > 0:07:38providing 250 square kilometres
0:07:38 > 0:07:42of protected land for endangered wildlife.
0:07:42 > 0:07:46Today, zebra keeper Polly will have the unique opportunity to compare
0:07:46 > 0:07:50the behaviour of the zebra there with those in her care.
0:07:50 > 0:07:52I'm looking forward to seeing giraffe and zebra
0:07:52 > 0:07:56and all the animals I look after. It'll be nice to see that, yeah,
0:07:56 > 0:07:58our animals are behaving as naturally as possible.
0:07:58 > 0:08:01It would be nice to see that out in the wild.
0:08:04 > 0:08:07Lewa is home not only to her zebra's wild cousins,
0:08:07 > 0:08:12but also to a rare and endangered species called the Grevy's zebra.
0:08:12 > 0:08:16The Grevy's plight is of major concern to Mike Watson,
0:08:16 > 0:08:19head of the Lewa Conservancy.
0:08:19 > 0:08:22We have 1,200 plains zebra,
0:08:22 > 0:08:26common zebra, 300 Grevy's zebra,
0:08:26 > 0:08:28Grevy's zebra being critically endangered
0:08:28 > 0:08:30and only really occurring in this part of Kenya.
0:08:30 > 0:08:32There's only 2,500 left in the world.
0:08:32 > 0:08:35And we've got 300 here on Lewa.
0:08:36 > 0:08:40The main reason Grevy's numbers have reduced so dramatically
0:08:40 > 0:08:42is because of habitat loss.
0:08:42 > 0:08:44The conflict between human settlement,
0:08:44 > 0:08:48between domestic livestock and wildlife competition for grazing,
0:08:48 > 0:08:53competition for water in particular, that loss has been a critical issue.
0:08:53 > 0:08:55And so what we've done is
0:08:55 > 0:08:58we've provided a habitat in which they can start to recover.
0:09:00 > 0:09:04Lewa is at the front line of wildlife conservation in Africa.
0:09:06 > 0:09:11Mary is one of the research officers dedicated to the daily welfare of
0:09:11 > 0:09:13the extremely rare Grevy's zebra.
0:09:13 > 0:09:18Every month, we go collecting images of all the animals that we see.
0:09:18 > 0:09:20Then we log it into the database.
0:09:20 > 0:09:23We are able to see the performance of every individual.
0:09:23 > 0:09:28The fine stripes of the Grevy's zebra are just like a fingerprint.
0:09:28 > 0:09:32With the Grevy's zebras, with the unique patterns each animal has,
0:09:32 > 0:09:36we are able to track through the database.
0:09:36 > 0:09:40Mary's job is to check the well-being of each of the 300 zebra
0:09:40 > 0:09:44by painstakingly cross-checking new photos
0:09:44 > 0:09:47with the ones she's taken the month before.
0:09:47 > 0:09:50You concentrate on the unique patterns.
0:09:50 > 0:09:53For example, you've got these three patterns here.
0:09:53 > 0:09:56These three. And then you check whether in the database
0:09:56 > 0:09:59the one that the system is imagining it is the one.
0:09:59 > 0:10:01But for this one, it is not.
0:10:01 > 0:10:04In this very difficult game of spot the difference,
0:10:04 > 0:10:08the computer doesn't always get it right.
0:10:08 > 0:10:10It is not a true match.
0:10:11 > 0:10:15No matter how much technology can aid conservation,
0:10:15 > 0:10:17the human touch remains vital.
0:10:17 > 0:10:22Park keepers Polly and James are joining Mary as she heads out
0:10:22 > 0:10:26into the wild to record this month's Grevy's population.
0:10:26 > 0:10:29So, we are preparing to start off our monthly patrol
0:10:29 > 0:10:31for the Grevy's zebras on Lewa.
0:10:31 > 0:10:36We've got GPS that we use to collect
0:10:36 > 0:10:38the location of that animal.
0:10:38 > 0:10:40So, is there... Are they radio-collared?
0:10:40 > 0:10:43Is that what that is for? No. No? It's not radio-collared.
0:10:43 > 0:10:45Just from where we have spotted the animal,
0:10:45 > 0:10:48you take the GPS location of that spot. Right.
0:10:51 > 0:10:55This is the first time James and Polly have done the challenging work
0:10:55 > 0:10:57of conservation out in the wild.
0:10:57 > 0:11:00It's hot and dusty and in rough terrain.
0:11:00 > 0:11:03But it will provide them with a wealth of information
0:11:03 > 0:11:04to take back to the park.
0:11:06 > 0:11:08Unlike the zebra Polly cares for,
0:11:08 > 0:11:13the animals here can be hunted and killed by lion, leopard or cheetah.
0:11:15 > 0:11:18At long last, Polly will finally get to observe
0:11:18 > 0:11:20zebra in their natural habitat.
0:11:22 > 0:11:24Seeing them out here in the wild is amazing.
0:11:24 > 0:11:27And seeing them, the plains mixed with the Grevy's is amazing.
0:11:27 > 0:11:29It's, yeah, overwhelming!
0:11:40 > 0:11:42In the last 20 years,
0:11:42 > 0:11:46the total population of the Grevy's zebra has declined by 50%.
0:11:48 > 0:11:53It's just incredible just to see them in this vastness.
0:11:53 > 0:11:56Just, you know, going about their daily lives.
0:11:58 > 0:12:03It really is just incredibly powerful just to see them living.
0:12:03 > 0:12:05It's brilliant!
0:12:05 > 0:12:07Now classed as endangered,
0:12:07 > 0:12:12the Grevy's zebra is teetering on the brink of extinction.
0:12:12 > 0:12:15The World Wildlife Fund estimates that every single year,
0:12:15 > 0:12:19at least 10,000 species become extinct on our planet.
0:12:21 > 0:12:23This is just happening every day.
0:12:23 > 0:12:27But, to us, we don't realise it.
0:12:27 > 0:12:30Unless you come out here and see how powerful it is.
0:12:36 > 0:12:40Side-by-side, the difference between the Grevy's and the plains zebra
0:12:40 > 0:12:43is clear. Although James needs a little help.
0:12:43 > 0:12:47Not being like a zebra expert, that's all,
0:12:47 > 0:12:50what's the difference between the two?
0:12:50 > 0:12:53The plains have thicker black stripes
0:12:53 > 0:12:55and wider bands of the white.
0:12:55 > 0:12:57And then the Grevy's,
0:12:57 > 0:13:00their stripes are a lot closer together and thinner.
0:13:00 > 0:13:02And then they've got a more defined white tummy to them.
0:13:02 > 0:13:07Those ears are like plates. They're absolutely massive!
0:13:07 > 0:13:11Yeah. Oh, yeah, it's actually quite distinct when you really look at it.
0:13:11 > 0:13:16Although the 300 Grevy's zebra are doing well, unlike back at the park,
0:13:16 > 0:13:18survival in the wild is tough.
0:13:20 > 0:13:24Of the recent 51 newly born foals, only 12 have survived.
0:13:26 > 0:13:29So our survival rates are really low.
0:13:29 > 0:13:32I see we've got a few foals out here now.
0:13:32 > 0:13:35What are their kind of chances of surviving?
0:13:35 > 0:13:37Because obviously, we're out in the wild.
0:13:37 > 0:13:40We don't want to stop lions doing what they do.
0:13:40 > 0:13:43Exactly. But we don't want to stop the zebras from growing
0:13:43 > 0:13:45in their population numbers.
0:13:45 > 0:13:48So, with the few that are there, what are their chances?
0:13:48 > 0:13:51Because we have got carnivores,
0:13:51 > 0:13:55we've got lions, we've got cheetahs, hyenas.
0:13:55 > 0:14:01So, if they are killed by the predators, we accept it is nature.
0:14:01 > 0:14:04Do you get upset about them?
0:14:04 > 0:14:06Well, you don't get upset,
0:14:06 > 0:14:10you get emotional to see a dead Grevy's zebra. But it's nature.
0:14:11 > 0:14:14Polly can't help compare the difference
0:14:14 > 0:14:17between the zebra here and those from home.
0:14:17 > 0:14:20It's weird to think that our zebra, even though they obviously
0:14:20 > 0:14:24keep their instincts and they are alert all the time.
0:14:24 > 0:14:27But they don't have to worry about... Predators. No!
0:14:27 > 0:14:31Whereas I've got a zebra that's 23.
0:14:31 > 0:14:34If Stephanie was out here, yeah, I'm not sure she'd last.
0:14:34 > 0:14:36She would not? Not at all!
0:14:39 > 0:14:44Back at the lodge, Polly reflects on Mary's dedicated study of the zebra.
0:14:44 > 0:14:49I think Mary is a very inspiring person.
0:14:49 > 0:14:51She's so passionate about what she does
0:14:51 > 0:14:54that talking to her was wonderful.
0:14:54 > 0:14:57And the information she gave, it was just...it just opened my eyes.
0:14:59 > 0:15:03I didn't realise that Grevy's zebra were so endangered.
0:15:05 > 0:15:08Overall, it's been a very emotional,
0:15:08 > 0:15:11rather overwhelming experience for Polly.
0:15:11 > 0:15:14Being out here, it's more than just seeing the animals.
0:15:14 > 0:15:21It's about learning how they're conserving not just one species,
0:15:21 > 0:15:24they're conserving the whole ecosystem.
0:15:24 > 0:15:28And I felt overwhelmed by the animals we'd seen,
0:15:28 > 0:15:31the beauty of the landscape.
0:15:31 > 0:15:33It makes me feel inspired.
0:15:35 > 0:15:39And just pass it on to the rest of the keepers
0:15:39 > 0:15:42and on to our visitors as well.
0:15:56 > 0:16:00As the seasons change, making sure the park's animals get
0:16:00 > 0:16:03a varied diet as they would in the wild is essential.
0:16:03 > 0:16:07And the keepers do their best to keep the diners happy.
0:16:07 > 0:16:08It is a very exciting moment.
0:16:08 > 0:16:10Not only am I about to meet the park's
0:16:10 > 0:16:13three western lowland gorillas for the very first time,
0:16:13 > 0:16:16but I'm going to help keeper Lauren here
0:16:16 > 0:16:18with a feed that has a difference.
0:16:18 > 0:16:20Tell me a bit about this feed.
0:16:20 > 0:16:22So we've put three different types of food out today.
0:16:22 > 0:16:25We've got some kale, some celery and some tomatoes.
0:16:25 > 0:16:28And you've divided them up as part of an experiment? Is this right?
0:16:28 > 0:16:30Yeah, we just want to see what their favourite one is
0:16:30 > 0:16:32at this time of year.
0:16:32 > 0:16:34Are we letting them all out at the same time? Who'll come out first?
0:16:34 > 0:16:37What we should do is let the two young boys out first
0:16:37 > 0:16:39so they can have a look and see what their favourite is.
0:16:39 > 0:16:41And then we'll let our silverback out
0:16:41 > 0:16:44so he can come out and he can get his fair share.
0:16:44 > 0:16:46OK, I'm pretty excited about this. Should we let them out?
0:16:46 > 0:16:49Should we do it, then? Let's do it!
0:16:49 > 0:16:53Who's that? So this is Alfie and that's Evindi who's behind him.
0:16:53 > 0:16:55Oh, look, aren't they magnificent?
0:16:55 > 0:16:58Oh, straight for the kale. Straight for the kale, yeah.
0:16:58 > 0:17:00Seen it all and what's he running for? And now, look!
0:17:00 > 0:17:03They're both going for the tomato as well.
0:17:03 > 0:17:05Evindi definitely preferred the tomatoes, didn't he?
0:17:05 > 0:17:08Evindi. Hey, save some for the others, Evindi!
0:17:08 > 0:17:11This is kind of how gorillas feed. They're very opportunistic,
0:17:11 > 0:17:14so they will just grab and run if they need to.
0:17:14 > 0:17:17Now, why experiment with different diets?
0:17:17 > 0:17:19I can understand about seasonality and things.
0:17:19 > 0:17:22But is it quite important that you know what they like and what they dislike?
0:17:22 > 0:17:25Yeah, what we like to do in the house is whenever we move
0:17:25 > 0:17:28them round the house, we like to give them a little reward.
0:17:28 > 0:17:30So if we ask them to come into a pen, we like to give them
0:17:30 > 0:17:33a positive reinforcement that they've done what we've asked.
0:17:33 > 0:17:34And it's a nice experience for them.
0:17:34 > 0:17:36So if we kind of know what they prefer,
0:17:36 > 0:17:39it's a lot easier to move them around the house.
0:17:39 > 0:17:42Where's our big silverback? Should we let him out as well? Yes!
0:17:42 > 0:17:44This is Kesho. Kesho.
0:17:44 > 0:17:46Yeah, 18-year-old silverback.
0:17:46 > 0:17:48He's big, isn't he? Big difference in size.
0:17:48 > 0:17:50Wow, he has a swagger.
0:17:50 > 0:17:53He does, yeah. Yes, definitely a typical silverback stance.
0:17:53 > 0:17:55Just make yourself look as big as possible,
0:17:55 > 0:17:57more threatening for the other males.
0:17:57 > 0:17:59That's why Alfie's grabbed as much as he can.
0:17:59 > 0:18:03He'll probably move off and keep that in a quiet corner somewhere.
0:18:03 > 0:18:05So, will Alfie hide it behind his back?
0:18:05 > 0:18:09Yep! Oh, look, so he's chasing, yeah! Isn't that amazing?
0:18:09 > 0:18:12So he is the dominant one and he gets his pick of the food.
0:18:12 > 0:18:14Yeah, it seems quite mean,
0:18:14 > 0:18:16but it is a totally natural gorilla behaviour.
0:18:16 > 0:18:19He is a lot bigger so he needs a lot more food.
0:18:19 > 0:18:21And now who have we got climbing up the tree?
0:18:21 > 0:18:23Very agile! Yeah, that's Alfie.
0:18:23 > 0:18:26Yes. Alfie's showing off. Why would he be going up there?
0:18:26 > 0:18:27Look, he's going to the highest point.
0:18:27 > 0:18:30Is that just to get a good view? Probably getting a good look at us,
0:18:30 > 0:18:33to see if we've got anything else for him. Is that what it is? Yeah.
0:18:33 > 0:18:36He wants to see if there's a bucket with more tomatoes in it? Yeah.
0:18:36 > 0:18:38The thumb is actually set back so it is more like a hand.
0:18:38 > 0:18:41And that is for climbing and also for grabbing as much food
0:18:41 > 0:18:44as they can in case the silverback comes over to take it.
0:18:44 > 0:18:46They'll run with it. And their absolute favourite
0:18:46 > 0:18:49if you really need them to do anything, what's the carrot?
0:18:49 > 0:18:52Definitely bananas. Bananas. So we try to limit how many they get.
0:18:52 > 0:18:54So they get one or two a day each.
0:18:54 > 0:18:57I mean, they are incredible to look at, aren't they?
0:18:57 > 0:18:59Do you ever tire of looking at these boys?
0:18:59 > 0:19:00No, never. No, I love them.
0:19:00 > 0:19:02I mean, we spend so much time with them
0:19:02 > 0:19:05that it's so hard not to fall in love with them.
0:19:05 > 0:19:07Lauren, thank you so much. Thank you, guys! There you go.
0:19:07 > 0:19:10The way to a gorilla's heart is with a tomato.
0:19:12 > 0:19:16The gorillas are just three of 1,000 different animals that all have
0:19:16 > 0:19:19specific dietary requirements.
0:19:19 > 0:19:22The need for menu reinvention never ends.
0:19:23 > 0:19:26Jean's now off to help keeper Nadia serve up
0:19:26 > 0:19:28a completely different tasting menu
0:19:28 > 0:19:32to the prickly customers over at the porcupine enclosure.
0:19:33 > 0:19:36What do you have here? Today, we are going to try them
0:19:36 > 0:19:37with some pears and sweet potato.
0:19:37 > 0:19:40It's something they don't have particularly often. OK.
0:19:40 > 0:19:41They never really have their food whole.
0:19:41 > 0:19:43So it'll be a little bit different for them.
0:19:43 > 0:19:47We've hid a few bits and pieces for them. So let's call them out.
0:19:47 > 0:19:49Brussels! Sprout!
0:19:49 > 0:19:51We've got some treats for you!
0:19:53 > 0:19:55I think he's found something.
0:19:55 > 0:19:58Oh, yeah! You can see his nose and his whiskers moving
0:19:58 > 0:20:00as he's having a good old sniff around.
0:20:00 > 0:20:04He's really working. Yeah. Here we go!
0:20:04 > 0:20:06He's right in there. He's absolutely loving it!
0:20:06 > 0:20:09Well done! He's pushing it all out of the way.
0:20:09 > 0:20:10No fear.
0:20:13 > 0:20:15So, what's he using, then?
0:20:15 > 0:20:17Is that...? Ah, he's grabbed it in his mouth.
0:20:17 > 0:20:20Yeah, these guys are rodents. So they've got really big front teeth.
0:20:20 > 0:20:24So those front teeth can come and grasp lots of big chunks of food.
0:20:24 > 0:20:25And they'll take them away.
0:20:25 > 0:20:28So, you'll see with Sprout he's just taking the peel off the potato.
0:20:28 > 0:20:31Yeah. Before he eats all the juicy good stuff inside.
0:20:31 > 0:20:35So that's quite nice. Fussy eaters? Yeah.
0:20:36 > 0:20:38So he managed it! The pear's down.
0:20:38 > 0:20:41Excellent work. She's just going to wander off.
0:20:42 > 0:20:45Take it off with her into the corner over there, I expect,
0:20:45 > 0:20:48away from Sprout before he finishes his potatoes.
0:20:48 > 0:20:50So we've seen a bit of both today,
0:20:50 > 0:20:53we've seen them picking some things up from the ground.
0:20:53 > 0:20:55Getting right inside the grass there.
0:20:55 > 0:20:57And going high up for that pear as well. Yeah.
0:20:57 > 0:21:01I think that was a really successful taste and sensory test.
0:21:01 > 0:21:02Yeah, I think so.
0:21:11 > 0:21:16Over on Penguin Island, the keepers are hoping for love.
0:21:16 > 0:21:18Since last year's malaria outbreak,
0:21:18 > 0:21:20there's been no pitter-patter of penguin feet.
0:21:22 > 0:21:26But now, four new boys have arrived to spice things up.
0:21:26 > 0:21:28To encourage the colony to start breeding,
0:21:28 > 0:21:31keeper Emma is preparing the nest boxes.
0:21:32 > 0:21:34We're trying to make it nice and comfortable
0:21:34 > 0:21:35so they actually come over themselves,
0:21:35 > 0:21:38and want to make it their own a little bit more.
0:21:38 > 0:21:39The males will bring in nest material.
0:21:39 > 0:21:42It's always the males that pick the nest boxes,
0:21:42 > 0:21:43so they'll pick the best ones.
0:21:43 > 0:21:46They'll pick various things, obviously this grassy stuff here.
0:21:46 > 0:21:49They'll bring twigs in, they'll bring stones in.
0:21:49 > 0:21:54Make it all really lovely, ready for the females to lay the eggs.
0:21:54 > 0:21:58It will be really exciting if we do have some more eggs,
0:21:58 > 0:22:00and we do get some more chicks.
0:22:00 > 0:22:05Merlin, Hugo, Maverick and Clive haven't paired up with anyone yet.
0:22:05 > 0:22:09But their arrival does seem to have had an effect
0:22:09 > 0:22:11on commitment-shy Redley.
0:22:11 > 0:22:14This two-timer has become a one-bird guy.
0:22:14 > 0:22:18But I'm afraid it's an all too predictable tale.
0:22:18 > 0:22:23He's traded in his ex, Peaches, for a younger model - Rihanna.
0:22:23 > 0:22:25Emma has a theory.
0:22:25 > 0:22:28Peaches and Redley have been together
0:22:28 > 0:22:30for a good two or three years now.
0:22:30 > 0:22:33They have also had eggs together as well.
0:22:33 > 0:22:36And they've always seemed to have got bored.
0:22:36 > 0:22:38And then they've left the eggs,
0:22:38 > 0:22:41and then of course the eggs have got cold and chicks have never emerged.
0:22:41 > 0:22:44So they're not particularly good parents.
0:22:44 > 0:22:48So that could be one of the reasons why he has decided to maybe find
0:22:48 > 0:22:49a different female penguin.
0:22:49 > 0:22:53If Redley and Rihanna successfully rear chicks together,
0:22:53 > 0:22:55that will bond their relationship
0:22:55 > 0:22:58and they should then stay together for life.
0:22:58 > 0:23:01A few days later, great news.
0:23:01 > 0:23:06Redley and Rihanna have taken up residence in one of the nest boxes.
0:23:06 > 0:23:08PENGUINS BRAY
0:23:08 > 0:23:11And the couple that bray together, stay together.
0:23:15 > 0:23:17This display strengthens their bond
0:23:17 > 0:23:21as well as advertising the fact that they're a happy couple.
0:23:21 > 0:23:24PENGUIN BRAYS
0:23:24 > 0:23:28But Redley's ex, Peaches, is left on the shelf.
0:23:28 > 0:23:36# I've heard that you're settled down
0:23:36 > 0:23:39# That you found a girl
0:23:39 > 0:23:43# And you're married now... #
0:23:43 > 0:23:45Peaches has spent basically
0:23:45 > 0:23:48the whole morning following Redley around.
0:23:48 > 0:23:50She still hasn't quite come to terms with the fact
0:23:50 > 0:23:52that he's clearly gone off with another female
0:23:52 > 0:23:54and doesn't want her around any more.
0:23:54 > 0:23:57She's followed him up to their nest, but if she gets too close,
0:23:57 > 0:24:00it doesn't matter that they used to be partners, he will attack her.
0:24:00 > 0:24:02And if Rihanna is at the front, then she really needs
0:24:02 > 0:24:04to move pretty sharpish because Rihanna won't...
0:24:04 > 0:24:06There'll be no holds barred when it comes to a nest.
0:24:06 > 0:24:09They will attack each other and try and get anyone away from their nest.
0:24:09 > 0:24:11PENGUIN BRAYS
0:24:13 > 0:24:16Redley's sticking with Rihanna.
0:24:16 > 0:24:21A reluctant Peaches takes the lonely path towards a new single life.
0:24:23 > 0:24:26# I hate to turn up out of the blue uninvited
0:24:26 > 0:24:30# But I couldn't stay away I couldn't fight it... #
0:24:30 > 0:24:33It is a little bit heartbreaking, because they do mourn.
0:24:33 > 0:24:35They do notice the loss of another.
0:24:35 > 0:24:39Peaches hasn't been herself for a while, she gets quite quiet.
0:24:39 > 0:24:41Won't run around with the other penguins,
0:24:41 > 0:24:43doesn't really want much attention from us,
0:24:43 > 0:24:45she just wants to sit in the corner by herself.
0:24:45 > 0:24:51# Sometimes it lasts in love but sometimes it hurts instead. #
0:25:01 > 0:25:05Redley and Rihanna spend the next few days in domestic bliss -
0:25:05 > 0:25:09preparing the nest, getting every twig just so.
0:25:09 > 0:25:14Then, keeper Georgia spots that they've produced not just one egg,
0:25:14 > 0:25:15but two!
0:25:15 > 0:25:18I'm really excited they're on the nest.
0:25:18 > 0:25:19If they're incubating properly,
0:25:19 > 0:25:22it shows signs that they're probably going to be good parents as well.
0:25:22 > 0:25:24So, fingers crossed they're doing a good job.
0:25:24 > 0:25:26Incubation takes around 40 days.
0:25:26 > 0:25:30Both parents should share the nesting duties 50/50,
0:25:30 > 0:25:33with one looking after the eggs, while the other goes to feed.
0:25:36 > 0:25:40Redley and Rihanna seem to be doing well at taking it in turns.
0:25:42 > 0:25:44The eggs are due to hatch any day now.
0:25:52 > 0:25:54Over at Animal Adventure,
0:25:54 > 0:25:58Senior keeper Kim has some new arrivals to introduce to Jean.
0:25:58 > 0:26:02Who have we got here? These are one of my brand-new favourites.
0:26:02 > 0:26:04These guys are called horsehead grasshoppers.
0:26:04 > 0:26:06Horsehead grasshoppers, right.
0:26:06 > 0:26:08I've not seen one of them before. Can we get one out...
0:26:08 > 0:26:10Yeah, of course we can. ..to get a closer look?
0:26:10 > 0:26:13So, these guys are from Peru, Ecuador, Brazil,
0:26:13 > 0:26:15those sort of areas.
0:26:15 > 0:26:18And they look a bit like stick insects.
0:26:18 > 0:26:20But they are... They look a bit like a twig, actually.
0:26:20 > 0:26:23They do. Very camouflaged in there. That's the idea.
0:26:23 > 0:26:27So they'll hang around on the edges of the rainforest eating just leaves.
0:26:27 > 0:26:29So we've got our special cameraman Geoff here.
0:26:29 > 0:26:31Wonderful. He's in charge of our special lens,
0:26:31 > 0:26:34and this is going to let you see the horsehead grasshopper
0:26:34 > 0:26:37really close-up. Oh Kim! It looks like we've got one feeding.
0:26:37 > 0:26:39Oh, yeah! Wow! Look at that!
0:26:39 > 0:26:42They are such a comedy-looking insect, they're so funny.
0:26:42 > 0:26:44Look at them! It's almost alien-like!
0:26:44 > 0:26:46What a strange little face.
0:26:46 > 0:26:49Horsehead grasshoppers, obviously because they've got a long face.
0:26:49 > 0:26:51I see where that comes from. Yeah, very long face.
0:26:51 > 0:26:55And what is going on down here? This is the mouth area, what, is there a lip there?
0:26:55 > 0:26:58Not overly, they've got mandibles. So their mouths sort of open up
0:26:58 > 0:27:01sideways as opposed to just sort of up and down like us. Hello!
0:27:01 > 0:27:05And they'll sort of munch sideways along the leaf.
0:27:05 > 0:27:07That is just so cool. You can see,
0:27:07 > 0:27:10obviously, where her eyes are quite high up on her head.
0:27:10 > 0:27:13So, parts of the mandible obviously let her know where the food is,
0:27:13 > 0:27:15do you see it? Yeah, I can see little feelers.
0:27:15 > 0:27:17It's just feeling along with the side of it.
0:27:17 > 0:27:19So she's not using her eyes to see that food at all,
0:27:19 > 0:27:21so it's those feelers that show her where the leaf is?
0:27:21 > 0:27:23Yeah. And she takes her time as well,
0:27:23 > 0:27:26just nibbling from one side to the other.
0:27:26 > 0:27:28Yeah. That is amazing, look at that.
0:27:28 > 0:27:33And then the back legs, they are absolutely enormous.
0:27:33 > 0:27:37And that's just the immense power, that they can jump sort of
0:27:37 > 0:27:4120 times the length of their body. So you enjoyed seeing those.
0:27:41 > 0:27:43That is so cool, that is so cool.
0:27:43 > 0:27:46There are lots of weird and wonderful animals here on the park,
0:27:46 > 0:27:48but this is one of my favourites.
0:27:48 > 0:27:50Definitely.
0:27:54 > 0:27:57The park is home to over 25 varieties of bird,
0:27:57 > 0:28:01many of which mix freely just as they would in the wild.
0:28:04 > 0:28:07And over in Africa, head of animal operations Darren
0:28:07 > 0:28:11is able to observe some of their wild counterparts
0:28:11 > 0:28:13at the local watering hole.
0:28:13 > 0:28:16It's a nice, quiet little oasis, and here,
0:28:16 > 0:28:19there are some lovely birds here. We have some sacred ibis.
0:28:19 > 0:28:23I'd be interested to see how many different species we can see
0:28:23 > 0:28:26because it's always great to get some ideas and add to ours.
0:28:31 > 0:28:34Egyptian geese, we won't be getting any of those.
0:28:34 > 0:28:39One of the quieter birds the park is already home to is the spoonbill.
0:28:39 > 0:28:43And here, just like there, a good wash is essential.
0:28:43 > 0:28:45The spoonbill is taking a nice bath.
0:28:45 > 0:28:47It sounds really daft, you think -
0:28:47 > 0:28:50why on earth do they need to have a bath because they live in water?
0:28:50 > 0:28:53But they have at least three layers of feathers.
0:28:53 > 0:28:55And what happens is they put
0:28:55 > 0:28:58a waterproof coating on those, and a dust...
0:28:58 > 0:29:00And, so you do get dirty.
0:29:00 > 0:29:02If you're a bird, you get dirty,
0:29:02 > 0:29:05and you need to make sure you get water down there,
0:29:05 > 0:29:07and clean up that grime and that dirt.
0:29:07 > 0:29:11Because your feathers are what are going to save your life one day.
0:29:11 > 0:29:13You're going to have to fly away from a predator.
0:29:13 > 0:29:15So the spoonbill's having a really good splash.
0:29:15 > 0:29:19Spoonbills get their name from their unusually shaped,
0:29:19 > 0:29:21but very practical beaks.
0:29:21 > 0:29:26It's a bit like a duck's bill for filtering.
0:29:26 > 0:29:30Now, they eat, obviously, small crustaceans and bugs and things.
0:29:30 > 0:29:33So, you'll see what they'll do is they'll put it down into the mud.
0:29:33 > 0:29:36He uses his paddle end of his beak
0:29:36 > 0:29:39to sort of sift his way through the...
0:29:39 > 0:29:41all the juicy grubs and things.
0:29:41 > 0:29:44Great design, you know, adaptations to the environment.
0:29:44 > 0:29:47Nature's got it. It's got it.
0:29:47 > 0:29:51Back at the park, the same birds enjoy a very similar environment
0:29:51 > 0:29:53which they share with the flamingos.
0:29:53 > 0:29:56Over in here is spoonbills. They're just coming over now, yeah,
0:29:56 > 0:30:00I think they've just spotted the food we put out for them.
0:30:00 > 0:30:01Now, the ibis,
0:30:01 > 0:30:03Is there a hierarchy between them?
0:30:03 > 0:30:07Do you notice whether, the spoonbill being slightly bigger...
0:30:07 > 0:30:10Not so much. Or... No, I'd say the ibis because there's more of them.
0:30:10 > 0:30:12They're a bit of a mob.
0:30:12 > 0:30:14Right. And the spoonbill are kind of a bit more sneaky with it.
0:30:14 > 0:30:17They'll just sneak in and they grab the bit
0:30:17 > 0:30:19and they run off to the water's edge.
0:30:19 > 0:30:21These birds, are they omnivorous
0:30:21 > 0:30:23or are they quite fussy about what they eat?
0:30:23 > 0:30:26They mainly eat fish, crustaceans, and insects.
0:30:26 > 0:30:28Yeah. So, yeah, they're very opportunistic.
0:30:28 > 0:30:31Whatever they kind of find in the waters, they'll have a go at it.
0:30:31 > 0:30:32They're not going to be fussy. Yeah.
0:30:32 > 0:30:34They're such elegant birds, aren't they?
0:30:34 > 0:30:38They are pretty, aren't they? Especially when they get into breeding season as well,
0:30:38 > 0:30:40they get a really nice red head and red knees.
0:30:40 > 0:30:42So, yeah, they look really smart.
0:30:42 > 0:30:45Can you get attached to birds in the same way that...
0:30:45 > 0:30:48Yeah. Definitely. ..other keepers get attached to mammals?
0:30:48 > 0:30:51Yeah, I came here to work with the gorillas,
0:30:51 > 0:30:52but I love the birds so much.
0:30:52 > 0:30:55The best thing about my job is helping the birds breed
0:30:55 > 0:30:57and watching them have babies.
0:30:57 > 0:30:59It's one of the best parts of the job, really.
0:30:59 > 0:31:01They are the best parents, some of them. Are they?
0:31:01 > 0:31:04Yeah, and it's so amazing just watching all the effort they put in.
0:31:04 > 0:31:06Making the nest, and looking after the eggs.
0:31:06 > 0:31:08And sometimes you'll see mammals and they just,
0:31:08 > 0:31:09they just don't look that bothered.
0:31:09 > 0:31:12But birds, they just... they really care.
0:31:12 > 0:31:13Now the spoonbills...
0:31:13 > 0:31:16Here they are! ..have come back round to see us.
0:31:16 > 0:31:19Seeing what the flamingos have got instead, I think.
0:31:19 > 0:31:20I think, because we've only got a few,
0:31:20 > 0:31:23they like to hang out in the big group of flamingos as well.
0:31:23 > 0:31:25Right, so safety in numbers.
0:31:25 > 0:31:28Yeah. Yeah. Yeah, hang out with their pink mates.
0:31:28 > 0:31:31We get a lot of questions whether the spoonbill are actually baby flamingos,
0:31:31 > 0:31:34so we have to explain that. No, they're completely different birds.
0:31:34 > 0:31:36The best way to tell them apart is by the beaks.
0:31:36 > 0:31:40By the beaks, yeah. It's always a joy to be here and to see them.
0:31:40 > 0:31:43And I know breeding season is kind of about to start, isn't it?
0:31:43 > 0:31:47Yeah, it's best time of the year. Yeah, so I hope it goes really well.
0:31:47 > 0:31:49Thank you. Thank you very much.
0:31:51 > 0:31:55Caring for an animal's needs in captivity can really be informed by
0:31:55 > 0:31:57observing those in the wild.
0:31:58 > 0:32:02Back in Kenya, the research project continues.
0:32:02 > 0:32:05Inspired by the work at Lewa Conservancy,
0:32:05 > 0:32:09keeper Polly has arranged to carry out a unique test of her own
0:32:09 > 0:32:14in order to get a vital indication as to how similar her zebra are
0:32:14 > 0:32:15to those in the wild.
0:32:15 > 0:32:18I'm just about to do an ethogram
0:32:18 > 0:32:21on one of the plains zebra that are out here.
0:32:21 > 0:32:23Someone back at the park
0:32:23 > 0:32:28is doing and ethogram on one of our plains zebras at home.
0:32:28 > 0:32:33An ethogram is the timed observation of the behaviour of one animal.
0:32:33 > 0:32:36The reason we want to do this
0:32:36 > 0:32:42is so we can compare the wild zebra behaviour with our captive zebra
0:32:42 > 0:32:47behaviour, to see if there's any differences and similarities.
0:32:47 > 0:32:50This study is incredibly important for the keepers.
0:32:50 > 0:32:54It will reveal where the park is going right with their care of
0:32:54 > 0:32:56the zebras, and crucially, where they could improve.
0:32:58 > 0:33:00Every minute, we're going to record the exact behaviour
0:33:00 > 0:33:05that the one zebra that I'm picking to focus on,
0:33:05 > 0:33:07what that zebra is doing at that time.
0:33:07 > 0:33:09Every minute, for the next hour,
0:33:09 > 0:33:12Polly will note the behaviour of a chosen zebra.
0:33:12 > 0:33:16And it's fellow-keeper Kat's job to keep time.
0:33:16 > 0:33:21So I need to pick a zebra that I can tell apart really from the others.
0:33:21 > 0:33:24I think I was going to go for the female that's got that little foal.
0:33:24 > 0:33:27Polly will be on the lookout for a range of behaviours,
0:33:27 > 0:33:30such as fighting or biting or being startled.
0:33:31 > 0:33:34And...she's grazing.
0:33:34 > 0:33:39I think we're going to have a fair bit of grazing, to be honest.
0:33:39 > 0:33:43But Polly has noticed more than just grazing.
0:33:43 > 0:33:47There's a few times where she's looked up and she's been alert.
0:33:47 > 0:33:49Just looking out for any predators,
0:33:49 > 0:33:52just having a look at what's going on.
0:33:52 > 0:33:56This is a ground-breaking study for the keepers.
0:33:57 > 0:33:59But for it to work, back at the park,
0:33:59 > 0:34:03keeper Tina must carry out the same observational ethogram
0:34:03 > 0:34:05with a zebra there.
0:34:05 > 0:34:08I'm hoping to get similar behaviours,
0:34:08 > 0:34:12because it means us, as keepers, are doing a good job,
0:34:12 > 0:34:15which isn't just about giving them food or providing them water.
0:34:15 > 0:34:17It's about providing them with an environment
0:34:17 > 0:34:20that encourages them to do natural behaviours,
0:34:20 > 0:34:23like grazing, running around, living in a herd.
0:34:23 > 0:34:26One of the problems of captive animal management,
0:34:26 > 0:34:27can be with fighting males.
0:34:27 > 0:34:30Sometimes you might have to move them on, because too many males,
0:34:30 > 0:34:32they will fight and that's what they do.
0:34:32 > 0:34:34They grow up, they want to become stallions.
0:34:34 > 0:34:36They want to become breeding males.
0:34:36 > 0:34:40Tina wants to focus on the stallion in the herd.
0:34:40 > 0:34:42We're looking for Martin, our stallion.
0:34:42 > 0:34:45And I believe he's just at the back over there.
0:34:47 > 0:34:50As Tina begins her timed observation,
0:34:50 > 0:34:52what will their joint research reveal?
0:34:52 > 0:34:55It would be brilliant to find out from Polly
0:34:55 > 0:34:59what exactly the zebras out there in Africa are currently doing.
0:34:59 > 0:35:03And my hope is that we will see exactly the same behaviours
0:35:03 > 0:35:05in our herd here.
0:35:08 > 0:35:12But back in Kenya, halfway through her timed study,
0:35:12 > 0:35:13Polly's got problems.
0:35:13 > 0:35:15The one that I picked,
0:35:15 > 0:35:17with the stripe that I thought I'd be able to pick out,
0:35:17 > 0:35:19is really hard to see now.
0:35:19 > 0:35:21All the zebras have started to move away.
0:35:21 > 0:35:23You've got them all mingling together,
0:35:23 > 0:35:26so the stripes are all blending.
0:35:26 > 0:35:27OK, that's you.
0:35:27 > 0:35:29Time's up.
0:35:29 > 0:35:31Polly must hear back from the park
0:35:31 > 0:35:35before she'll know just what the test reveals.
0:35:36 > 0:35:38While she waits, she has the opportunity
0:35:38 > 0:35:41to fully appreciate where she is.
0:35:42 > 0:35:46It definitely is just a moment where we can just sit
0:35:46 > 0:35:49and feel peaceful and just take it all in
0:35:49 > 0:35:51and watch the animals for a little while.
0:35:51 > 0:35:52It's really nice, as well.
0:35:52 > 0:35:56This is lovely to actually have that bit of tranquillity
0:35:56 > 0:35:58and that bit of downtime.
0:35:58 > 0:36:01It's been an incredible experience. It's...
0:36:01 > 0:36:03Yeah. It's really...
0:36:05 > 0:36:06It's really lovely.
0:36:06 > 0:36:08It's really nice.
0:36:16 > 0:36:18Back at the park, in the emu enclosure,
0:36:18 > 0:36:22Jean has arranged to help keeper Gemma with bath time.
0:36:24 > 0:36:25Hi, Gemma!
0:36:25 > 0:36:27Hi, Jean! Hi, are you preparing this for the emus?
0:36:27 > 0:36:30I sure am, yeah. It's a lovely day today.
0:36:30 > 0:36:31Yeah, perfect.
0:36:31 > 0:36:33I've never met them before. What's their names?
0:36:33 > 0:36:36So we have Biscuit, Bounty and Buttons.
0:36:36 > 0:36:38Good names. Yes. And I have to say, looking at them,
0:36:38 > 0:36:40they really remind me of the ostrich.
0:36:40 > 0:36:42Well, the neck's not as long, obviously.
0:36:42 > 0:36:44No, they are very closely related to the ostrich.
0:36:44 > 0:36:46Just the ostrich is a lot taller.
0:36:47 > 0:36:49It's bath time, right? It is bath time, yeah.
0:36:49 > 0:36:52And I hear that they love water. They do, they do love water.
0:36:52 > 0:36:54Naturally, they would swim. They can swim.
0:36:54 > 0:36:56Really? They're very, very good swimmers.
0:36:56 > 0:36:59That surprises me, I thought they were known for being fast runners.
0:36:59 > 0:37:02That as well. They've got everything, but, sadly,
0:37:02 > 0:37:04we don't have a swimming pool here for them.
0:37:04 > 0:37:06So it's their pond. Yeah, this is bath time for them.
0:37:06 > 0:37:07So let's get them over.
0:37:07 > 0:37:09One of my favourite things about being in the park
0:37:09 > 0:37:11is the calls you've got for all the animals.
0:37:11 > 0:37:12So let's hear this one.
0:37:12 > 0:37:15OK, so, if I do the first one, you can then call them in, as well.
0:37:15 > 0:37:18OK, I'll give it a go. OK, so here comes Buttons now.
0:37:18 > 0:37:20But it's...emu!
0:37:20 > 0:37:22Emu! Emu! Emu! There he is!
0:37:22 > 0:37:24That's it, there you go!
0:37:24 > 0:37:26And on a hot day like this, there's nothing better
0:37:26 > 0:37:29than having a dip in a nice bath, is there? Exactly!
0:37:29 > 0:37:30And it's just the same for these guys.
0:37:30 > 0:37:33When they're that hot, they need to cool down.
0:37:33 > 0:37:34And this is the best way for them.
0:37:34 > 0:37:35There you go, Buttons.
0:37:38 > 0:37:41And what about these beautiful feathers, is it OK to get them wet?
0:37:41 > 0:37:44It's absolutely fine to get them wet, yeah.
0:37:44 > 0:37:46I mean, they're designed for all weathers.
0:37:46 > 0:37:48So they dry off very, very quickly.
0:37:48 > 0:37:50So the wetter, the better.
0:37:50 > 0:37:54Under all those feathers, they've got some very, very hot skin.
0:37:54 > 0:37:56And they originate from Australia,
0:37:56 > 0:37:58so they'd be used to pretty high temperatures, wouldn't they?
0:37:58 > 0:38:00Oh, yes. Yeah, definitely.
0:38:00 > 0:38:02But they do tend to stay quite near water
0:38:02 > 0:38:04in case of predators and things like that.
0:38:04 > 0:38:06So if they do need to get away, then they can swim.
0:38:06 > 0:38:09Oh, she's having a little swim there! A little roll around, yeah.
0:38:09 > 0:38:12A little splash in the pool, she's really enjoying that. She loves it.
0:38:12 > 0:38:15Can I have a go? Of course you can, yeah.
0:38:32 > 0:38:35They're loving this. And I'm really enjoying it, too!
0:38:35 > 0:38:38Almost as much fun as bath time at home.
0:38:45 > 0:38:50In Africa, Polly has been conducting a study of wild zebra.
0:38:50 > 0:38:51While back at the park,
0:38:51 > 0:38:55Tina has been doing the same thing with their captive zebra,
0:38:55 > 0:38:58hoping to see if their behaviours match.
0:39:01 > 0:39:05I'm really interested to hear what Tina's found from her study.
0:39:05 > 0:39:09It'd be nice to know that our zebra are comfortable displaying
0:39:09 > 0:39:13the same behaviour as their wild counterparts do.
0:39:14 > 0:39:16Tina's finally ready to phone through with her results.
0:39:18 > 0:39:19Hello? Hi, Tina!
0:39:19 > 0:39:23Which zebra did you decide to do for your ethogram?
0:39:23 > 0:39:26I went for Marti, our stallion. OK.
0:39:26 > 0:39:30Admittedly, I did lose track of the female towards the end.
0:39:30 > 0:39:33I got a little confused when they all got a bit mixed up.
0:39:33 > 0:39:36What were your kind of results? I had a lot of grazing.
0:39:36 > 0:39:38Yeah, there's quite a lot of grazing.
0:39:38 > 0:39:41So he's just doing his usual pottering about,
0:39:41 > 0:39:44grazing, and just relaxing in the sunshine.
0:39:44 > 0:39:47I only had a couple of times where the female I was looking at
0:39:47 > 0:39:49was looking up and being alert.
0:39:49 > 0:39:51But generally, they're all really relaxed.
0:39:51 > 0:39:53Yeah, it was quite relaxed here.
0:39:53 > 0:39:57So, the tests confirm the park is getting things right.
0:39:57 > 0:39:59It's nice that they seem to be doing the same
0:39:59 > 0:40:02as what I saw in our wild zebras out here.
0:40:02 > 0:40:05I was surprised that the ones out here were so relaxed,
0:40:05 > 0:40:09because I'd assumed that there'd be a lot more head up, looking round,
0:40:09 > 0:40:11making sure everything was safe.
0:40:11 > 0:40:15But they just seemed really, really chilled out, which was nice to see.
0:40:15 > 0:40:18I always think, you know, our guys,
0:40:18 > 0:40:20you know, we always just think they are just quite relaxed
0:40:20 > 0:40:22because they know they're safe,
0:40:22 > 0:40:24they know we're here to look after them.
0:40:24 > 0:40:27But the fact that, out there in Africa,
0:40:27 > 0:40:30they're doing exactly the same, really, which is brilliant.
0:40:30 > 0:40:32Generally, good result, really.
0:40:32 > 0:40:34All right, Polly, I'll let you get on.
0:40:34 > 0:40:36Thanks, Tina. Bye!
0:40:36 > 0:40:39That was good that we kind of got
0:40:39 > 0:40:42the same behaviours as their wild cousins.
0:40:42 > 0:40:45That's fantastic to kind of know that.
0:40:45 > 0:40:47It did make me miss our zebras.
0:40:49 > 0:40:52And every zebra I'm seeing, I'm comparing them to our zebras.
0:40:52 > 0:40:54I'm seeing marks in their stripes, so I think,
0:40:54 > 0:40:55"Oh, that looks like Kabebe!"
0:40:55 > 0:40:57Or, "Oh, that one looks like Marti!"
0:40:57 > 0:41:00So I do love it here,
0:41:00 > 0:41:02but it will be nice to see our zebras when I get home.
0:41:11 > 0:41:13It's nearly the end of the show, but before we left,
0:41:13 > 0:41:15Kate and I could not resist
0:41:15 > 0:41:18coming back to Scandal Island with keeper George.
0:41:18 > 0:41:21Rihanna and Redley, are they still together?
0:41:21 > 0:41:24They are together now. So Peaches has lost out, I'm afraid.
0:41:24 > 0:41:25Oh, no!
0:41:25 > 0:41:31So, I mean, is Redley proving a reasonably monogamous partner,
0:41:31 > 0:41:35or is he still behaving badly on the side?
0:41:35 > 0:41:36If he's not on the nest,
0:41:36 > 0:41:39he does go and see Peaches for a little chat and a catch up.
0:41:39 > 0:41:41Shocking! Yeah. Really?
0:41:41 > 0:41:44But Peaches has been having some luck, as well.
0:41:44 > 0:41:47Well, I was going to ask, because Peaches, she does deserve love.
0:41:47 > 0:41:49Doesn't she? Yeah. And so, has she found somebody?
0:41:49 > 0:41:51Merlin, one of our new penguins,
0:41:51 > 0:41:54he's going up and making himself known to Peaches. Oh, yeah?
0:41:54 > 0:41:56So, fingers and toes crossed.
0:41:56 > 0:42:00And how's she responding to Merlin's sort of, you know, courtship?
0:42:00 > 0:42:03It does depend on what mood she's in on the day, yeah.
0:42:03 > 0:42:05Georgia, I love this idea that you and all the staff here,
0:42:05 > 0:42:09all the keepers sitting there in the staff room with your cups of tea,
0:42:09 > 0:42:11just talking about the penguin gossip.
0:42:11 > 0:42:13It is. It's like a soap, watching the soap every day.
0:42:13 > 0:42:16It's something new. Lucky you. Yeah.
0:42:16 > 0:42:20Well, let's hope there's the pitter-patter of tiny flippers...
0:42:20 > 0:42:22Yes! ..sometime soon. Very exciting, hopefully.
0:42:22 > 0:42:23George, thank you very much.

0:43:35 > 0:43:37SHE SINGS
0:43:37 > 0:43:40But how will they manage on MasterChef?
