0:00:00 > 0:00:05- Rural Wales offers some of the most - spectacular sights in Britain.
0:00:08 > 0:00:12- But the countryside - offers much more than just views.
0:00:12 > 0:00:15- It's home - to some our best-loved wildlife.
0:00:16 > 0:00:20- But one group of mammals - is living a secret life.
0:00:22 > 0:00:25- By burrowing - in tunnels miles underground...
0:00:26 > 0:00:30- ..the way - these animals live their lives...
0:00:30 > 0:00:35- ..has been a mystery until now.
0:00:35 > 0:00:39- We're going to do something - that's never been done before.
0:00:39 > 0:00:44- By uncovering some of these - burrowers' tunnels and chambers...
0:00:44 > 0:00:48- ..we're going to recreate - an artificial habitat.
0:00:48 > 0:00:51- For the first time ever...
0:00:51 > 0:00:55- ..we'll get an insight - into their secret lives underground.
0:00:55 > 0:01:01- We'll discover what water voles - do all day in their tunnels...
0:01:02 > 0:01:07- ..how rabbits cope with nurturing - dozens of offspring each year...
0:01:07 > 0:01:10- ..and how small badgers - learn to cope...
0:01:11 > 0:01:13- ..with the big world - beyond the sett.
0:01:13 > 0:01:17- Join me, Iolo Williams, - as we venture...
0:01:17 > 0:01:21- ..to the magical, hidden, - subterranean world of the burrowers.
0:01:45 > 0:01:47- Spring has sprung...
0:01:47 > 0:01:52- ..signifying a crucial time - for the new generation of burrowers.
0:01:52 > 0:01:56- It's turned into - the survival of the fittest.
0:01:56 > 0:01:59- Eventually, - each one of our animals....
0:01:59 > 0:02:02- ..must turn their backs - on their burrows...
0:02:02 > 0:02:04- ..and face the big, wide world.
0:02:05 > 0:02:08- In the forthcoming episodes, - we'll discover...
0:02:08 > 0:02:12- ..the importance - of these burrows to the mammals...
0:02:12 > 0:02:15- ..at this stage in their lives.
0:02:15 > 0:02:17- We're back with the rabbits...
0:02:18 > 0:02:21- ..in this - remarkable artificial warren.
0:02:21 > 0:02:25- Spring is here and - the rabbits have been very busy...
0:02:25 > 0:02:27- ..birthing their young.
0:02:27 > 0:02:29- Our warren in Devon...
0:02:30 > 0:02:32- ..is a hive of activity.
0:02:32 > 0:02:36- The first litter is the offspring - of the dominant female...
0:02:36 > 0:02:38- ..at the beginning of the year.
0:02:38 > 0:02:42- Since then, the dominant male - has been busy mating.
0:02:43 > 0:02:47- Each of the does - now has a nest of baby rabbits.
0:02:47 > 0:02:51- Soon they will be fully formed, - like these confident kits.
0:02:51 > 0:02:54- But they still require - the safety of their warren...
0:02:55 > 0:02:59- ..with its tunnels and chambers.
0:02:59 > 0:03:01- I'm down at the bottom.
0:03:01 > 0:03:06- This nest - has been here longer than the rest.
0:03:07 > 0:03:11- I can take a peek inside - and watch the young kits.
0:03:11 > 0:03:17- Judging by the amount of fur they - have, I'd say they're two weeks old.
0:03:17 > 0:03:21- They're dirty creatures, - to be honest.
0:03:21 > 0:03:25- If you could smell the aroma - in here, you'd know what I mean.
0:03:28 > 0:03:31- They regularly - race through the tunnels.
0:03:31 > 0:03:34- The two bucks constantly fight...
0:03:35 > 0:03:38- ..to establish - which of them is the dominant one...
0:03:38 > 0:03:41- ..that will mate - with all the females.
0:03:41 > 0:03:43- They lose their fur when they fight.
0:03:44 > 0:03:47- This litter - was born a couple of weeks ago.
0:03:48 > 0:03:50- They're confidently curious...
0:03:51 > 0:03:54- ..under - the watchful eye of the mother.
0:03:54 > 0:03:57- She knows - her young are safe underground...
0:03:57 > 0:04:00- ..and the warren - soon becomes a nursery.
0:04:00 > 0:04:05- To learn more about the warren and - the rabbits' lives underground...
0:04:05 > 0:04:08- ..I returned - to Bicton Park in Devon.
0:04:10 > 0:04:13- Earlier in the series...
0:04:13 > 0:04:16- ..we came across an empty warren.
0:04:16 > 0:04:21- It was fumigated - to reveal each of the entrances.
0:04:21 > 0:04:23- Its size was measured underground.
0:04:23 > 0:04:27- During winter, workmen - pumped concrete into the warren...
0:04:28 > 0:04:30- ..to form a mould.
0:04:31 > 0:04:35- A team of volunteers - has removed the mud...
0:04:35 > 0:04:39- ..to find out if - this experiment has been a success.
0:04:40 > 0:04:42- Let's find out.
0:04:44 > 0:04:47- The warren's structure - is plain to see.
0:04:47 > 0:04:51- Though I've walked over - numerous warrens in my time...
0:04:51 > 0:04:54- ..I had no idea - what existed beneath my feet.
0:04:56 > 0:04:59- Wow! Here we are.
0:04:59 > 0:05:02- The rabbit warren - has been uncovered...
0:05:02 > 0:05:04- ..for the first time ever.
0:05:04 > 0:05:06- Look how big it is.
0:05:07 > 0:05:10- I didn't expect it to be - as big as this, I have to admit.
0:05:11 > 0:05:13- There are flat pieces on top...
0:05:14 > 0:05:16- ..which are the entrances.
0:05:16 > 0:05:19- You can see the numerous tunnels.
0:05:19 > 0:05:23- They form a spider's web...
0:05:23 > 0:05:25- ..stretching far and wide.
0:05:25 > 0:05:31- There are also chambers - resembling large bulbs...
0:05:31 > 0:05:33- ..dotted all around.
0:05:34 > 0:05:39- The tunnels are interconnected - with numerous escape routes...
0:05:40 > 0:05:42- ..in every corner.
0:05:42 > 0:05:47- To give you some sort of idea - how much effort was involved here...
0:05:47 > 0:05:50- ..the earth the rabbits - have managed to dig up...
0:05:51 > 0:05:54- ..is the equivalent of a human...
0:05:54 > 0:05:58- ..extracting 40 tonnes of earth - by hand and foot...
0:05:59 > 0:06:01- ..which is quite remarkable.
0:06:01 > 0:06:05- There are other things - I'd like to show you.
0:06:05 > 0:06:08- Here's one of the holes - leading underground.
0:06:09 > 0:06:11- The tunnels are wide enough...
0:06:11 > 0:06:16- ..to allow two rabbits - to pass each other underground.
0:06:16 > 0:06:18- They have to be wide enough...
0:06:19 > 0:06:22- ..to accommodate - two rabbits side by side.
0:06:22 > 0:06:25- When animals live underground...
0:06:25 > 0:06:29- ..other creatures - either move in with them...
0:06:29 > 0:06:31- ..or kick them out.
0:06:31 > 0:06:34- If you look closely here...
0:06:35 > 0:06:39- ..you'll notice that tunnel - is very narrow and short...
0:06:39 > 0:06:41- ..approximately 1.5m long.
0:06:42 > 0:06:46- This isn't - a rabbit's tunnel but a rat's.
0:06:46 > 0:06:52- A family of rats has moved in - to live alongside the rabbits.
0:06:56 > 0:06:59- It's only when you stand back...
0:06:59 > 0:07:03- ..that you notice - its scale and complexity.
0:07:03 > 0:07:05- That one's a complete warren.
0:07:05 > 0:07:08- It's been there for around 20 years.
0:07:08 > 0:07:11- I doubt it would get much bigger.
0:07:11 > 0:07:15- What's the first stage? - This the beginning of the process.
0:07:15 > 0:07:18- One rabbit - would've started this warren.
0:07:18 > 0:07:22- It would've - either attracted other rabbits...
0:07:22 > 0:07:25- ..or have been used - as a nest to produce offspring.
0:07:26 > 0:07:29- It gradually extends - into new chambers and tunnels.
0:07:30 > 0:07:34- The question is, why is this - located so close to the old warren?
0:07:34 > 0:07:38- The reason is that - the dominant female rabbit...
0:07:39 > 0:07:42- ..the head - of the warren over there...
0:07:42 > 0:07:44- ..has kicked one of the rabbits out.
0:07:45 > 0:07:49- It might've grown too large - or they might've fallen out.
0:07:49 > 0:07:51- It's obvious that the rabbit...
0:07:51 > 0:07:55- ..has started - building a new warren here.
0:07:55 > 0:07:57- If it hadn't been disturbed...
0:07:57 > 0:08:01- ..perhaps both warrens - would've eventually linked up.
0:08:12 > 0:08:16- Rabbits aren't the only mammals - to burrow at speed.
0:08:16 > 0:08:20- The badgers are busy inspecting - and using their new burrow.
0:08:22 > 0:08:25- Life wasn't always - this easy for them.
0:08:25 > 0:08:29- Each of them has been rescued - after being found orphaned...
0:08:30 > 0:08:33- ..in fields and woods.
0:08:33 > 0:08:37- Staff at Secret World rescue centre - have reared them.
0:08:37 > 0:08:41- Individually, - these badgers would not survive.
0:08:41 > 0:08:44- As a group, - they've a better chance of survival.
0:08:45 > 0:08:49- One of the badgers arrived - at the centre later than the rest.
0:08:49 > 0:08:53- It's a challenge for her to fit - into the already-established group.
0:08:54 > 0:08:56- She will have to earn her place...
0:08:56 > 0:08:59- ..and deal with - the most dominant badger.
0:09:00 > 0:09:05- The first thing they do upon - entering the sett is make a bed...
0:09:05 > 0:09:08- ..so that they - can all sleep together.
0:09:08 > 0:09:10- If you remember previously...
0:09:11 > 0:09:13- ..they were very small creatures.
0:09:14 > 0:09:18- It's surprising how quickly - they've grown and developed.
0:09:18 > 0:09:21- They're almost four months old now.
0:09:21 > 0:09:24- It's nice to see - the way they've bonded.
0:09:25 > 0:09:27- They resemble a close-knit family.
0:09:28 > 0:09:33- You'd never think they'd all come - from different parts of the country.
0:09:33 > 0:09:35- They've settled well.
0:09:36 > 0:09:39- There are two above me - - one is lying on top of the other.
0:09:40 > 0:09:44- There are a couple beneath me too. - The chambers are divided.
0:09:45 > 0:09:48- There's a sleeping chamber, - a sewage chamber...
0:09:48 > 0:09:51- ..and a chamber in which to play.
0:09:51 > 0:09:56- It's surprising the way things have - changed in a short space of time.
0:09:56 > 0:09:58- But it's a crucial step...
0:09:58 > 0:10:03- ..because eventually, they will be - reintroduced into the wild.
0:10:03 > 0:10:08- They must co-operate as a family, - and at the moment, that's happening.
0:10:10 > 0:10:15- Having seen the badgers begin to - co-operate in our artificial sett...
0:10:15 > 0:10:18- ..Owen Bidder and I - headed into the woods...
0:10:18 > 0:10:21- ..to see - how badgers co-exist in the wild.
0:10:21 > 0:10:25- Are these three female?
0:10:25 > 0:10:26- Yes, I think so.
0:10:26 > 0:10:29- Yes, I think so.- - They're small, aren't they?
0:10:29 > 0:10:32- Yes, they are small, - but the male is larger.
0:10:32 > 0:10:37- The females have narrower heads.
0:10:37 > 0:10:41- What strikes you when you - see badgers up close like this...
0:10:42 > 0:10:45- ..is their prominent - black and white faces.
0:10:45 > 0:10:48- Why do they have that pattern?
0:10:48 > 0:10:51- We believe - it's a way of communicating...
0:10:52 > 0:10:55- ..how ferocious they can be.
0:10:55 > 0:11:00- They're saying, "I can fight, - so don't try and eat me."
0:11:00 > 0:11:05- The head and the mouth - are very prominent.
0:11:05 > 0:11:08- They have sharp teeth - to defend themselves.
0:11:08 > 0:11:10- Something's frightened them.
0:11:11 > 0:11:14- I think it's the wind.
0:11:15 > 0:11:18- There's a strong wind today - and they don't like it...
0:11:19 > 0:11:22- ..because they can't hear - animals approaching.
0:11:22 > 0:11:25- But they like a gentle wind...
0:11:25 > 0:11:31- ..because it allows them - to smell the habitat.
0:11:31 > 0:11:36- A wind allows them - to sniff out the territory.
0:11:36 > 0:11:40- They commonly use - a fallen branch of a tree...
0:11:40 > 0:11:44- ..to start - burrowing a hole underneath.
0:11:45 > 0:11:47- It provides shelter for them.
0:11:47 > 0:11:52- Exactly. - It also helps conceal the burrow.
0:11:59 > 0:11:59- .
0:12:01 > 0:12:01- Subtitles
0:12:01 > 0:12:03- Subtitles- - Subtitles
0:12:06 > 0:12:12- Our young burrowers are growing and - developing successfully by now...
0:12:12 > 0:12:17- ..but one pair of mammals - has been very slow to breed.
0:12:31 > 0:12:36- The relationship between the water - voles was difficult at first...
0:12:36 > 0:12:38- ..with the pair at loggerheads.
0:12:38 > 0:12:41- But the female - has since formed a nest.
0:12:41 > 0:12:45- It's impossible to tell - how many offspring she's produced.
0:12:50 > 0:12:53- When water voles - are as tiny as this...
0:12:53 > 0:12:56- ..they're very sensitive - to any disturbance.
0:12:56 > 0:13:00- But we can finally see - that there are three offspring...
0:13:00 > 0:13:03- ..which are - the size of my little finger.
0:13:03 > 0:13:07- They are deaf, blind - and dependent on their mother.
0:13:07 > 0:13:10- But soon, their eyes open, - they gain weight...
0:13:10 > 0:13:13- ..and are ready to leave the nest.
0:13:13 > 0:13:15- They're only a fortnight old...
0:13:15 > 0:13:19- ..and remarkably, they're already - half the size of the mother.
0:13:20 > 0:13:22- They grow incredibly quickly.
0:13:22 > 0:13:25- It's characteristic of water voles.
0:13:25 > 0:13:28- Like many small mammals...
0:13:28 > 0:13:32- ..they must learn - to develop quickly.
0:13:32 > 0:13:36- While they are still suckling, - they are weaned very quickly...
0:13:37 > 0:13:40- ..and begin eating solid food, - as it were.
0:13:40 > 0:13:43- This combination - of rapid development...
0:13:44 > 0:13:47- ..and constant feeding - in order to grow...
0:13:48 > 0:13:51- ..enables them - to gain necessary weight.
0:13:51 > 0:13:54- So many of them perish - due to malnutrition...
0:13:55 > 0:13:58- ..and inbreeding - among the water vole population.
0:13:59 > 0:14:02- They must gain substantial weight...
0:14:02 > 0:14:06- ..in order for them - to survive in the wild.
0:14:06 > 0:14:10- Call it natural selection, - if you wish.
0:14:10 > 0:14:15- Those that thrive will breed - and ensure the species' continues.
0:14:15 > 0:14:18- Water voles - need to consume enough...
0:14:18 > 0:14:21- ..to gain an extra one gram - in weight every single day.
0:14:22 > 0:14:25- That's equivalent to - a woman giving birth to a baby...
0:14:25 > 0:14:28- ..who'd weigh - five stone in a few weeks.
0:14:28 > 0:14:33- Feeding is crucial. The mother keeps - a watchful eye on her smallest.
0:14:33 > 0:14:35- If he doesn't gain weight...
0:14:36 > 0:14:41- ..he'll find it hard to survive when - the time comes to leave the burrow.
0:14:41 > 0:14:44- Her family of three - could become a family of two.
0:14:53 > 0:14:57- We've created artificial habitats - for each of our burrowers.
0:14:57 > 0:15:02- But there's another burrower - that's different from the rest.
0:15:02 > 0:15:06- This mammal is reluctant - to leave the safety of the tunnels.
0:15:08 > 0:15:14- It was necessary to create a special - framework of boxes and tunnels...
0:15:14 > 0:15:18- ..to film this next burrower - - the mole.
0:15:18 > 0:15:22- Moles live - a solitary, underground existence...
0:15:22 > 0:15:27- ..and rarely see daylight, - making them hard to film.
0:15:27 > 0:15:30- Very little footage - of moles exists..
0:15:30 > 0:15:33- ..but after a long wait, - we've captured them on film.
0:15:34 > 0:15:40- Idris Jones has been catching moles - for farmers and gardeners for years.
0:15:40 > 0:15:45- He's accustomed to the molehills - which anger so many gardeners.
0:15:45 > 0:15:48- But he's - never seen moles underground.
0:15:49 > 0:15:52- You say this is a feeding run?
0:15:52 > 0:15:54- Yes. They live in that hedge.
0:15:55 > 0:15:59- They're woodland creatures and - like living in a safe environment.
0:15:59 > 0:16:01- There's no risk of flooding here.
0:16:02 > 0:16:05- So they live over there - and just venture out to feed?
0:16:06 > 0:16:08- Yes, just to feed.
0:16:09 > 0:16:12- I always thought - they were field animals...
0:16:12 > 0:16:17- ..that foraged in the woods, - but it's the other way around.
0:16:17 > 0:16:20- So the feeding run - is essentially just a tunnel?
0:16:21 > 0:16:23- Yes, a network of small tunnels.
0:16:24 > 0:16:27- They're three dimensional - rather than flat.
0:16:27 > 0:16:30- Worms and so on - fall into the runs...
0:16:30 > 0:16:35- ..and they eat them - and sometimes store them.
0:16:35 > 0:16:39- They bite the heads off - - their saliva contains anaesthetic...
0:16:40 > 0:16:45- ..and they bury them in the earth - and keep them for the winter.
0:16:45 > 0:16:46- They're incredible, aren't they?
0:16:46 > 0:16:49- They're incredible, aren't they?- - Yes, they're clever creatures.
0:16:49 > 0:16:56- This mole is a rare example of - the breed because it's been rescued.
0:16:56 > 0:16:59- Moles rarely leave - their underground tunnels.
0:17:00 > 0:17:04- When they do, they're often killed - by the gardener or farmer.
0:17:04 > 0:17:08- This female was caught by a hunter - who handed her over...
0:17:08 > 0:17:10- ..for the purpose of the experiment.
0:17:14 > 0:17:18- Remarkably, there's - a similarity between the mole...
0:17:18 > 0:17:22- ..and a mammal from a completely - different habitat - the seal.
0:17:23 > 0:17:26- They both have smooth bodies...
0:17:26 > 0:17:31- ..allowing them to move freely - through the water and the earth.
0:17:32 > 0:17:35- Unlike most mammals, - their legs aren't beneath the body.
0:17:35 > 0:17:39- The seal's and mole's front legs - are at the side of the body.
0:17:40 > 0:17:42- In effect, they are both swimming.
0:17:42 > 0:17:46- The mole swims through earth - and the seal through water.
0:17:56 > 0:17:59- Two of the young water voles - are doing well...
0:18:00 > 0:18:02- ..and are daily gaining weight.
0:18:02 > 0:18:04- They are very playful.
0:18:05 > 0:18:08- With only a few days to go - until they leave the burrow...
0:18:08 > 0:18:11- ..the third sibling - is very underweight.
0:18:11 > 0:18:14- He must learn - to eat like his parents.
0:18:14 > 0:18:16- Lots and lots all the time!
0:18:19 > 0:18:24- They are voracious eaters, consuming - 8% of their bodyweight every day.
0:18:26 > 0:18:30- They eat - 227 different species of plants.
0:18:30 > 0:18:34- There's one food - they're particularly fond of.
0:18:35 > 0:18:40- For most of the year, water voles - eat grass, reeds and rushes...
0:18:41 > 0:18:43- ..similar to this vegetation here.
0:18:43 > 0:18:47- But it's very coarse to consume...
0:18:47 > 0:18:49- ..and detrimental to teeth.
0:18:49 > 0:18:53- Dyfrig Jones, - our water vole expert...
0:18:53 > 0:18:57- ..has been studying these mammals - for many years.
0:18:57 > 0:19:00- This is - the skull of a water vole, Dyfrig.
0:19:01 > 0:19:05- The way it's had to adapt - to the wild is plain to see.
0:19:05 > 0:19:09- Look at its front teeth. - They're very yellow.
0:19:10 > 0:19:14- The enamel is incredibly strong - and they grow continuously.
0:19:14 > 0:19:19- The way the top front teeth work - in conjunction with the bottom...
0:19:19 > 0:19:23- ..allows them - to tear different textures.
0:19:23 > 0:19:25- Think about a willow tree.
0:19:25 > 0:19:29- They can tear the branches - with their teeth...
0:19:29 > 0:19:32- ..to get at the nutrients inside.
0:19:32 > 0:19:37- There's an obvious gap between - the front teeth and the back teeth.
0:19:37 > 0:19:40- They call it the diastema gap.
0:19:40 > 0:19:46- Yes, it's characteristic - of the way they chew their food...
0:19:46 > 0:19:49- ..and the nature - of the food they eat.
0:19:49 > 0:19:54- They use the front teeth to tear and - the back teeth to grind their food.
0:19:54 > 0:20:01- The droppings of the water vole - are a source of interest.
0:20:01 > 0:20:05- They're - completely and utterly smooth...
0:20:06 > 0:20:10- ..irrespective - of what they've eaten and digested.
0:20:11 > 0:20:13- They're completely smooth...
0:20:13 > 0:20:18- ..and that's due to the structure - of the skull and those back teeth.
0:20:18 > 0:20:22- But there's another reason why - the water voles need strong teeth.
0:20:22 > 0:20:28- Unlike any of our other burrowers, - they burrow with their teeth.
0:20:28 > 0:20:32- Their feet are tiny, - so they burrow with their teeth...
0:20:32 > 0:20:35- ..and kick the earth - that has been displaced...
0:20:35 > 0:20:38- ..out of the tunnel - with their back feet.
0:20:38 > 0:20:42- They're able to dig tunnels - of up to 70 metres or more...
0:20:42 > 0:20:48- ..and cut through underground roots, - occasionally causing trees to fall.
0:20:49 > 0:20:53- Soon, the young water voles - will have to dig their own holes.
0:20:53 > 0:20:58- This is true of all the burrowers, - including the badgers.
0:20:58 > 0:21:01- It's inherent in them to burrow.
0:21:02 > 0:21:04- The face is long, - with a thin snout...
0:21:04 > 0:21:09- ..which gradually thickens as it - reaches the neck and then the body.
0:21:09 > 0:21:13- The legs are short but the paws - are incredibly powerful.
0:21:14 > 0:21:17- Bear in mind - that these are orphaned badgers.
0:21:17 > 0:21:23- Will they know how to burrow without - the guidance of their parents?
0:21:26 > 0:21:29- Sometimes, when badgers - live in a sett in the wild...
0:21:30 > 0:21:35- ..parts of the tunnels collapse - and badgers must dig their way out.
0:21:35 > 0:21:41- We've deposited earth in one of the - tunnels to see what the badgers do.
0:21:41 > 0:21:45- They instinctively know - how to dig their way out.
0:21:45 > 0:21:49- Though they have never seen - another badger do this...
0:21:49 > 0:21:52- ..they know exactly what to do...
0:21:52 > 0:21:55- ..and dig their way out right away.
0:21:55 > 0:22:01- Years ago, badgers - were the prey of wolves and bears.
0:22:01 > 0:22:04- Since those animals - have disappeared...
0:22:04 > 0:22:07- ..the badgers are now - at the top of the food chain.
0:22:08 > 0:22:12- These days, they are - the most common predator in Wales.
0:22:13 > 0:22:15- They eat anything and everything.
0:22:15 > 0:22:21- They eat roots, fruit, worms, - beetles, mice and rabbits.
0:22:21 > 0:22:27- They are the most voracious animal - of all the burrowers.
0:22:27 > 0:22:32- But there is one thing - that the badger cannot escape...
0:22:32 > 0:22:34- ..and that's TB.
0:22:34 > 0:22:38- These are about to embark - on their final experiment.
0:22:38 > 0:22:43- If they pass the test, they - will be reintroduced into the wild.
0:22:43 > 0:22:46- But if they fail, - they will be culled.
0:22:54 > 0:22:57- So we've seen - our young burrowers...
0:22:57 > 0:23:02- ..grow, learn and adapt to their - lives underground and above ground.
0:23:02 > 0:23:06- We've seen the way our burrowers - have adapted perfectly...
0:23:07 > 0:23:09- ..to their underground lives...
0:23:09 > 0:23:12- ..and we've also met the mole...
0:23:12 > 0:23:15- ..with its - remarkable burrowing skills.
0:23:15 > 0:23:18- Next week, - some of the young animals...
0:23:19 > 0:23:22- ..are ready - to venture into the big, wide world.
0:23:22 > 0:23:25- And we'll see - another family of badgers...
0:23:26 > 0:23:29- ..preparing - for their release into the wild.
