-Rural Wales offers some of the most -spectacular sights in Britain. | 0:00:00 | 0:00:05 | |
-But the countryside -offers much more than just views. | 0:00:08 | 0:00:12 | |
-It's home -to some of our best-loved wildlife. | 0:00:12 | 0:00:15 | |
-But one group of mammals -is living a secret life. | 0:00:16 | 0:00:20 | |
-By burrowing -in tunnels miles underground... | 0:00:22 | 0:00:25 | |
-..the way -these animals live their lives... | 0:00:26 | 0:00:30 | |
-..has been a mystery until now. | 0:00:30 | 0:00:35 | |
-We're going to do something -that's never been done before. | 0:00:35 | 0:00:39 | |
-By uncovering some of these -burrowers' tunnels and chambers... | 0:00:39 | 0:00:44 | |
-..we're going to recreate -an artificial habitat. | 0:00:44 | 0:00:48 | |
-For the first time ever... | 0:00:48 | 0:00:51 | |
-..we'll get an insight -into their secret lives underground. | 0:00:51 | 0:00:55 | |
-We'll discover what water voles -do every day in their tunnels... | 0:00:55 | 0:01:01 | |
-..how rabbits cope with nurturing -dozens of offspring each year... | 0:01:02 | 0:01:07 | |
-..and how small badgers -learn to cope... | 0:01:07 | 0:01:10 | |
-..with the big world -beyond the sett. | 0:01:11 | 0:01:13 | |
-Join me, Iolo Williams, -as we venture... | 0:01:13 | 0:01:17 | |
-..to the magical, hidden, -subterranean world of the burrowers. | 0:01:17 | 0:01:21 | |
-Subtitles | 0:01:22 | 0:01:24 | |
-Midsummer, and our time -with the burrowers is almost over. | 0:01:45 | 0:01:49 | |
-The warren -is overrun with young rabbits. | 0:01:50 | 0:01:54 | |
-The water voles are more than ready -for their release into the wild. | 0:01:57 | 0:02:02 | |
-The badgers are also ready -to face the big, wide world. | 0:02:04 | 0:02:09 | |
-In line with this experiment... | 0:02:12 | 0:02:15 | |
-..we wanted to learn more about the -least familiar burrower of them all. | 0:02:15 | 0:02:20 | |
-The mole. | 0:02:20 | 0:02:23 | |
-This is an animal -that rarely surfaces above ground. | 0:02:30 | 0:02:35 | |
-After long spells of darkness... | 0:02:35 | 0:02:38 | |
-..the hidden cameras -captured the mole on film. | 0:02:38 | 0:02:41 | |
-It was living -in this collection of boxes... | 0:02:42 | 0:02:44 | |
-..using some of them to nest -and others to store food... | 0:02:45 | 0:02:49 | |
-..moving between the boxes -through inter-connecting tubes. | 0:02:49 | 0:02:54 | |
-This mole is special -because she was rescued. | 0:02:54 | 0:02:57 | |
-Moles are regarded as pests for -creating molehills on golf courses. | 0:02:57 | 0:03:03 | |
-This one was caught -by a professional mole catcher. | 0:03:03 | 0:03:07 | |
-Normally it would've been killed. | 0:03:07 | 0:03:10 | |
-This is one of the most -interesting animals in Britain. | 0:03:10 | 0:03:13 | |
-It spends -most of its life underground. | 0:03:14 | 0:03:18 | |
-It is the best burrower -out of all the burrowing mammals. | 0:03:19 | 0:03:22 | |
-They exist -in the safety of the tunnels. | 0:03:25 | 0:03:27 | |
-Unlike the other burrowers... | 0:03:28 | 0:03:30 | |
-..they have a lonely -and self-sufficient existence. | 0:03:30 | 0:03:34 | |
-In summer, they must find a mate -in order to breed... | 0:03:34 | 0:03:38 | |
-..deep underground. | 0:03:38 | 0:03:40 | |
-The chances of seeing newborn moles -are relatively slim. | 0:03:41 | 0:03:45 | |
-No-one had ever -filmed baby moles before... | 0:03:45 | 0:03:49 | |
-..until the 1970s, -when Peter Stafford's footage... | 0:03:49 | 0:03:54 | |
-..won him the Wildlife -Photographer of the Year award. | 0:03:54 | 0:03:58 | |
-The young burrowers -won't start burrowing... | 0:03:59 | 0:04:02 | |
-..until they're two months old. | 0:04:02 | 0:04:04 | |
-They will learn from -inspecting the mother's tunnels. | 0:04:05 | 0:04:09 | |
-They compete -with their mother for food... | 0:04:09 | 0:04:12 | |
-..which eventually -drives them out of their tunnels. | 0:04:12 | 0:04:16 | |
-They must establish their own -territories around the mother's. | 0:04:16 | 0:04:20 | |
-This is when the burrowers -venture above ground... | 0:04:20 | 0:04:24 | |
-..before burrowing new tunnels. | 0:04:24 | 0:04:26 | |
-They sometimes burrow -at the roadside or near buildings. | 0:04:26 | 0:04:30 | |
-They must then resurface -and try again. | 0:04:30 | 0:04:33 | |
-Moles are never happy above ground. | 0:04:33 | 0:04:35 | |
-Owls, like many other animals... | 0:04:43 | 0:04:46 | |
-..eat food -that is difficult to digest. | 0:04:46 | 0:04:49 | |
-They swallow food whole. | 0:04:49 | 0:04:51 | |
-The food -is broken down in the crop... | 0:04:51 | 0:04:54 | |
-..and the meat -is separated from the bone. | 0:04:54 | 0:04:57 | |
-The bones and fur -are compressed into a ball... | 0:04:57 | 0:05:00 | |
-..and vomited out of the beak. | 0:05:01 | 0:05:03 | |
-By collecting -and analysing these balls... | 0:05:05 | 0:05:08 | |
-..it's possible to tell -which small mammals... | 0:05:09 | 0:05:12 | |
-..inhabit -the same habitat as the owl. | 0:05:12 | 0:05:15 | |
-I know you've studied -the barn owl, Kelvin... | 0:05:19 | 0:05:22 | |
-..and collected their pellets... | 0:05:22 | 0:05:24 | |
-..which consist of fur and bones... | 0:05:24 | 0:05:27 | |
-..that they've vomited -from the mouth. | 0:05:28 | 0:05:30 | |
-What information have you gleaned? | 0:05:31 | 0:05:32 | |
-What information have you gleaned? - -I've two reasons for doing this. | 0:05:32 | 0:05:34 | |
-It's a great way -of engaging children. | 0:05:35 | 0:05:37 | |
-By studying what they eat... | 0:05:38 | 0:05:40 | |
-..you get a sample -of the territory they inhabit. | 0:05:40 | 0:05:43 | |
-Some of these -have come from Dinas Dinlle. | 0:05:44 | 0:05:47 | |
-I know the skull has come from -Dinas Dinlle, at least. | 0:05:47 | 0:05:51 | |
-But the skull of the water vole -has come from Lleyn. | 0:05:51 | 0:05:55 | |
-Of all the pellets I've collected, -that's the only one from Lleyn. | 0:05:55 | 0:05:59 | |
-That goes to show -how rare the water vole has become. | 0:06:00 | 0:06:03 | |
-We're old enough to remember them -but now they're preyed on by mink. | 0:06:03 | 0:06:09 | |
-That's not a very big skull because, -quite often, they can be big. | 0:06:09 | 0:06:15 | |
-They wouldn't eat -the large ones whole, would they? | 0:06:15 | 0:06:19 | |
-According to our research, yes. | 0:06:19 | 0:06:21 | |
-They must swallow them whole. | 0:06:21 | 0:06:23 | |
-They must swallow them whole. - -That's one heck of a mouthful! | 0:06:23 | 0:06:25 | |
-You also have an example -of the mole's remains. | 0:06:25 | 0:06:29 | |
-Do you often come across them? | 0:06:31 | 0:06:33 | |
-No, not very often. It's been -pulverised in the bird's gullet. | 0:06:34 | 0:06:38 | |
-It swallows the prey whole... | 0:06:38 | 0:06:41 | |
-..and then its stomach acid -digests what it can... | 0:06:41 | 0:06:45 | |
-..and leaves -the fur and bone for excretion. | 0:06:45 | 0:06:48 | |
-The mole's skull isn't very strong. | 0:06:48 | 0:06:51 | |
-What we have here are two chins... | 0:06:52 | 0:06:54 | |
-..and are they two hips? | 0:06:54 | 0:06:57 | |
-No, I'll tell you what they are. | 0:06:57 | 0:06:59 | |
-I've an example of these here. | 0:07:00 | 0:07:02 | |
-They're the main bones of the arm - -the humerus. | 0:07:02 | 0:07:06 | |
-Notice their shape. | 0:07:07 | 0:07:09 | |
-A human's humerus -looks like a proper bone... | 0:07:09 | 0:07:12 | |
-..the kind you'd find -in the mouth of a dog in a cartoon. | 0:07:12 | 0:07:16 | |
-But this humerus -looks almost like a hip. | 0:07:16 | 0:07:20 | |
-Because they're so strong, -they use them to burrow. | 0:07:21 | 0:07:24 | |
-They're very wide, with plenty of -room for the muscles to contract... | 0:07:24 | 0:07:30 | |
-..giving them strength and power. | 0:07:30 | 0:07:33 | |
-I've brought something else along... | 0:07:33 | 0:07:36 | |
-..that's been discarded in -an owl pellet - the skull of a mole. | 0:07:36 | 0:07:40 | |
-As you say, it looks very fragile. | 0:07:41 | 0:07:43 | |
-It's long and thin. | 0:07:43 | 0:07:45 | |
-Check out those teeth. | 0:07:45 | 0:07:47 | |
-They're very sharp. -The only thing it eats are worms. | 0:07:48 | 0:07:52 | |
-You need teeth like that -to catch them. | 0:07:52 | 0:07:55 | |
-And to kill them. -Nature has a reason for everything. | 0:07:55 | 0:07:59 | |
-This is a good way -of mapping an animal like this. | 0:07:59 | 0:08:03 | |
-There's no need to lay traps. | 0:08:03 | 0:08:05 | |
-You just have to collect -their remains. | 0:08:06 | 0:08:08 | |
-You can tell what species they are - -short-tailed voles or bank voles... | 0:08:09 | 0:08:14 | |
-..as well as those they aren't. | 0:08:14 | 0:08:16 | |
-It's interesting when you're -sitting at home at night... | 0:08:16 | 0:08:20 | |
-..and it's cold and wet outside -to have a hobby like this. | 0:08:21 | 0:08:24 | |
-The family might not be so happy -but is passes the time! | 0:08:25 | 0:08:28 | |
-The young badgers have left the sett -and are inspecting the enclosure. | 0:08:47 | 0:08:51 | |
-They must learn how to live -above ground as well as underground. | 0:08:52 | 0:08:56 | |
-So far, they've been fed by those -who are looking after them... | 0:08:56 | 0:09:01 | |
-..with all kinds of special foods. | 0:09:01 | 0:09:03 | |
-But now they have to learn -to fend for themselves... | 0:09:04 | 0:09:08 | |
-..by catching worms. | 0:09:09 | 0:09:10 | |
-Research has been carried out... | 0:09:11 | 0:09:13 | |
-..and within a two-hour period... | 0:09:14 | 0:09:16 | |
-..a person watched a badger -eat 1,803 worms. | 0:09:16 | 0:09:21 | |
-A worm weighs around three grams... | 0:09:21 | 0:09:26 | |
-..so that's the equivalent -to three kilograms of worms. | 0:09:26 | 0:09:30 | |
-Worms are vital to their survival. | 0:09:30 | 0:09:32 | |
-That's a hefty weight... | 0:09:33 | 0:09:35 | |
-..when you consider that badgers... | 0:09:35 | 0:09:38 | |
-..don't weigh -more than 10kg-11kg themselves. | 0:09:38 | 0:09:42 | |
-They're eating a third -of their bodyweight in one night. | 0:09:42 | 0:09:46 | |
-Worms are a vital food source. | 0:09:47 | 0:09:49 | |
-If it's a dry summer, -badgers find it difficult to forage. | 0:09:50 | 0:09:54 | |
-They're capable of finding other -foods but worms are their staple. | 0:09:54 | 0:09:59 | |
-On a wet night, when the worms -surface above ground... | 0:10:01 | 0:10:07 | |
-..badgers venture out early evening -to have their fill. | 0:10:07 | 0:10:10 | |
-Our badgers are obviously capable -of finding food. | 0:10:14 | 0:10:17 | |
-They sniff out the worms... | 0:10:18 | 0:10:20 | |
-..and eat them in the same way -as badgers do in the wild. | 0:10:20 | 0:10:23 | |
-It's a good sign they'll find their -main food supply once released. | 0:10:24 | 0:10:28 | |
-But life beyond the sett -is by no means easy. | 0:10:30 | 0:10:33 | |
-When they return underground, they -bring unwelcome guests with them. | 0:10:39 | 0:10:44 | |
-One of the disadvantages -of living in an underground sett... | 0:10:46 | 0:10:50 | |
-..is that mites co-habit with you. | 0:10:50 | 0:10:53 | |
-Fleas are -the scourge of animals everywhere. | 0:10:54 | 0:10:58 | |
-Fleas burrow in the fur -and feed on the poor animal's blood. | 0:11:01 | 0:11:06 | |
-In spite of all the scratching, -the fleas' legs cling to the fur... | 0:11:11 | 0:11:16 | |
-..making it very difficult -to get rid of them. | 0:11:16 | 0:11:19 | |
-In spite of the fleas, badgers -are incredibly clean animals. | 0:11:24 | 0:11:29 | |
-Even our orphaned badgers have -learnt to keep their nests clean... | 0:11:29 | 0:11:33 | |
-..by dragging the straw outside -for it to dry in the sun and wind. | 0:11:33 | 0:11:38 | |
-What materials -do they use for their nests? | 0:11:45 | 0:11:48 | |
-Predominantly straw, but whatever -they can find in their surroundings. | 0:11:48 | 0:11:53 | |
-Fern, moss and vegetation -that dries quite easily. | 0:11:53 | 0:11:58 | |
-I've seen them drag their nests -outside for them to dry... | 0:11:58 | 0:12:02 | |
-..before dragging them -back in again. | 0:12:02 | 0:12:06 | |
-Yes, they do that. | 0:12:07 | 0:12:08 | |
-In warm weather, -they pull out the straw to air it. | 0:12:09 | 0:12:12 | |
-That must get rid of the fleas and -whatever else is living in it... | 0:12:13 | 0:12:17 | |
-..before taking it -back below ground. | 0:12:17 | 0:12:20 | |
-So it's true -that they're clean creatures? | 0:12:21 | 0:12:24 | |
-Most definitely. | 0:12:24 | 0:12:26 | |
-As summer passes, -our experiment comes to an end. | 0:12:33 | 0:12:37 | |
-But the young burrowers aren't ready -to leave their homes just yet. | 0:12:38 | 0:12:42 | |
-These final steps towards -independence are the most important. | 0:12:43 | 0:12:47 | |
-Each of our burrowers has developed -a very different strategy... | 0:12:51 | 0:12:55 | |
-..to prepare them -for the big, wide world. | 0:12:56 | 0:12:58 | |
-The badgers have created -a close-knit social unit... | 0:12:59 | 0:13:04 | |
-..which gives the group stability... | 0:13:04 | 0:13:07 | |
-..and will be useful -when they come to raise their young. | 0:13:07 | 0:13:12 | |
-The rabbits, on the other hand, -are completely different. | 0:13:12 | 0:13:16 | |
-Their strategy is to breed non-stop. | 0:13:17 | 0:13:19 | |
-High numbers of rabbits to -replace those killed by predators. | 0:13:20 | 0:13:24 | |
-The water vole -has a far more orderly strategy. | 0:13:24 | 0:13:28 | |
-. | 0:13:34 | 0:13:34 | |
-Subtitles | 0:13:38 | 0:13:38 | |

-The female water vole -is nurturing her second litter. | 0:13:58 | 0:14:03 | |
-The mother's milk helps them -gain a gram of weight every day. | 0:14:03 | 0:14:08 | |
-But there's no sign -of the first litter. | 0:14:08 | 0:14:11 | |
-The mother has driven them out of -the burrow to live on the riverbank. | 0:14:14 | 0:14:19 | |
-Three of them -are now fending for themselves. | 0:14:19 | 0:14:22 | |
-They must be careful. | 0:14:23 | 0:14:25 | |
-In the wild, a young water vole -is a tasty snack... | 0:14:25 | 0:14:28 | |
-..for its arch-rival, the mink. | 0:14:29 | 0:14:31 | |
-How will they be able to defend -themselves once they're released? | 0:14:35 | 0:14:40 | |
-Luckily, their father is burrowing -tunnels whilst foraging for food. | 0:14:40 | 0:14:46 | |
-The young water voles -need a new home. | 0:14:46 | 0:14:49 | |
-By observing -the actions of their father... | 0:14:49 | 0:14:52 | |
-..they learn to do the same. | 0:14:53 | 0:14:55 | |
-Soon they'll have small shelters -in which to hide when necessary. | 0:14:56 | 0:15:00 | |
-Thrown out of their home at three -weeks of age might seem cruel... | 0:15:01 | 0:15:05 | |
-..but it's essential -to ensure the water voles' survival. | 0:15:05 | 0:15:11 | |
-Since they're -so ferociously territorial... | 0:15:13 | 0:15:17 | |
-..it's remarkable to think -that the female in particular... | 0:15:17 | 0:15:21 | |
-..allows her firstborn -to stay relatively close. | 0:15:22 | 0:15:27 | |
-Once the second litter is born... | 0:15:27 | 0:15:31 | |
-..the population -continues to rise... | 0:15:31 | 0:15:34 | |
-..so there must be enough room -for them to spread out. | 0:15:35 | 0:15:38 | |
-The first litter stays close... | 0:15:39 | 0:15:41 | |
-..whereas the second litter -is pushed further away... | 0:15:41 | 0:15:45 | |
-..from the mother's territory... | 0:15:46 | 0:15:48 | |
-..and forced to find new habitats. | 0:15:48 | 0:15:51 | |
-There might be another female 50 -metres away with the same structure. | 0:15:51 | 0:15:56 | |
-The young -are pushed further and further away. | 0:15:57 | 0:16:03 | |
-One of the main -conservational problems... | 0:16:03 | 0:16:06 | |
-..is tracking the young that are -consistently pushed further away. | 0:16:06 | 0:16:11 | |
-That's a difficult strategy... | 0:16:11 | 0:16:14 | |
-..because you're -pushing the young further away... | 0:16:14 | 0:16:18 | |
-..knowing they are the prey -of buzzards, otters and so on. | 0:16:18 | 0:16:23 | |
-Yes, -it is a very difficult strategy. | 0:16:24 | 0:16:28 | |
-But it's important in order -for that strategy to work... | 0:16:28 | 0:16:33 | |
-..and for the population -to be self-sufficient. | 0:16:34 | 0:16:38 | |
-The connection -between the populations is vital. | 0:16:38 | 0:16:41 | |
-Those ties must be formed -in an ideal habitat... | 0:16:42 | 0:16:46 | |
-..where there's enough room -for them to burrow. | 0:16:46 | 0:16:50 | |
-The males, for example... | 0:16:50 | 0:16:53 | |
-..or the young boys, as it were, -that are kicked out... | 0:16:54 | 0:16:58 | |
-..must be able to travel -and find other females... | 0:16:58 | 0:17:02 | |
-..so that -the genetic diversity is varied. | 0:17:02 | 0:17:09 | |
-These connections are crucial... | 0:17:09 | 0:17:12 | |
-..as are the habitats which -connect these metapopulations... | 0:17:13 | 0:17:18 | |
-..over a sprawling landscape. | 0:17:19 | 0:17:23 | |
-There's -a large population in Wales... | 0:17:23 | 0:17:26 | |
-..especially in the upland areas. | 0:17:26 | 0:17:29 | |
-The habitat is widespread... | 0:17:30 | 0:17:33 | |
-..encompassing numerous dykes... | 0:17:33 | 0:17:36 | |
-..and pools. | 0:17:36 | 0:17:38 | |
-Within those small pools -are different populations. | 0:17:39 | 0:17:43 | |
-It's those important connections -that make the strategy work. | 0:17:44 | 0:17:48 | |
-Rabbit numbers continue to multiply -in the warren... | 0:18:02 | 0:18:07 | |
-..with the dominant female -holding her own. | 0:18:07 | 0:18:10 | |
-She keeps other rabbits at bay. | 0:18:10 | 0:18:13 | |
-She and the dominant male... | 0:18:13 | 0:18:15 | |
-..rule the roost. | 0:18:15 | 0:18:17 | |
-There are now 40 kits -in the rabbit warren. | 0:18:17 | 0:18:21 | |
-But as numbers increase, -one pair of subservient rabbits... | 0:18:22 | 0:18:26 | |
-..must live in the chambers -at the bottom of the warren. | 0:18:26 | 0:18:30 | |
-Though the doe -has recently given birth... | 0:18:30 | 0:18:33 | |
-..the dominant male -prepares to mate with her. | 0:18:33 | 0:18:36 | |
-But the subservient male challenges -him and it leads to a fight... | 0:18:36 | 0:18:41 | |
-..in and out of the tunnels. | 0:18:42 | 0:18:44 | |
-This behaviour -endangers the newborns. | 0:18:45 | 0:18:48 | |
-When the mother returns to the nest, -she finds blood. | 0:18:48 | 0:18:52 | |
-It appears -that most of the kits are alive... | 0:18:52 | 0:18:56 | |
-..but the fight between the two -bucks has left at least one dead. | 0:18:57 | 0:19:01 | |
-This is one of the females that's -been thrown out of the warren. | 0:19:04 | 0:19:09 | |
-She has started burrowing a new -tunnel as a nest for her offspring. | 0:19:10 | 0:19:14 | |
-This is how a new warren begins. | 0:19:14 | 0:19:17 | |
-In the winter -we studied an empty warren. | 0:19:26 | 0:19:29 | |
-In a unique experiment, -we filled the warren with concrete. | 0:19:30 | 0:19:34 | |
-Once it had set, -we dug up the earth... | 0:19:34 | 0:19:37 | |
-..to uncover an elaborate warren. | 0:19:37 | 0:19:39 | |
-This is the first time -such a task has been undertaken. | 0:19:40 | 0:19:43 | |
-The warren we built has shown us -many new and exciting things. | 0:19:44 | 0:19:49 | |
-But there's one thing -it cannot show us. | 0:19:50 | 0:19:53 | |
-For the first time, we're about to -find out how a wild warren grows... | 0:19:57 | 0:20:01 | |
-..to accommodate -a rising number of rabbits. | 0:20:01 | 0:20:04 | |
-Experts in mapping technology -collate data... | 0:20:05 | 0:20:08 | |
-..that will enable us -to create a 3D scan of the warren. | 0:20:08 | 0:20:12 | |
-The warren -has developed in three stages... | 0:20:13 | 0:20:17 | |
-..with each part corresponding -to a new generation of rabbits. | 0:20:17 | 0:20:22 | |
-This is the first part, with -short tunnels, large chambers... | 0:20:25 | 0:20:29 | |
-..and numerous entrances. | 0:20:29 | 0:20:31 | |
-The second part -seems larger than the first... | 0:20:31 | 0:20:35 | |
-..with fewer slants and -more tunnels between every chamber. | 0:20:35 | 0:20:40 | |
-The third part, the most recent, -looks longer than the other two. | 0:20:43 | 0:20:47 | |
-But looking -at the design mathematically... | 0:20:49 | 0:20:52 | |
-..the tunnels are almost -the same size and length... | 0:20:53 | 0:20:57 | |
-..even in the most recent section... | 0:20:57 | 0:21:00 | |
-..where the chambers -look further apart. | 0:21:01 | 0:21:04 | |
-It's interesting to think animals -adhere to mathematical rules. | 0:21:04 | 0:21:08 | |
-They can't afford -to do things in a haphazard way. | 0:21:09 | 0:21:12 | |
-There's a chance for -the subservient rabbits to escape... | 0:21:15 | 0:21:19 | |
-..and create a new warren -that would thrive in the future. | 0:21:19 | 0:21:24 | |
-The badgers have shown they are -capable of surviving in the wild. | 0:21:40 | 0:21:45 | |
-But one test remains. | 0:21:48 | 0:21:50 | |
-They must prove -they can build their own sett. | 0:21:50 | 0:21:53 | |
-The young badgers know instinctively -what to do. It's inherent in them. | 0:21:53 | 0:21:59 | |
-They have already -been burrowing their own sett. | 0:22:01 | 0:22:06 | |
-These animals -have given us an insight... | 0:22:20 | 0:22:23 | |
-..into -their secret lives underground. | 0:22:23 | 0:22:26 | |
-We've learnt so many new things. | 0:22:26 | 0:22:28 | |
-We now know the shape and form -of a rabbit warren in the wild... | 0:22:31 | 0:22:35 | |
-..and the individual role the -water vole plays in its survival. | 0:22:38 | 0:22:43 | |
-We know that moles can exist -underground in total darkness... | 0:22:46 | 0:22:51 | |
-..and how a group -of orphaned badgers... | 0:22:55 | 0:22:58 | |
-..can form a lifelong relationship. | 0:22:59 | 0:23:02 | |
-Our journey underground... | 0:23:02 | 0:23:04 | |
-..has been an incredible adventure. | 0:23:04 | 0:23:07 | |
