0:00:03 > 0:00:04My name's Steve Backshall...
0:00:05 > 0:00:09..and this is my search for the Deadly 60.
0:00:10 > 0:00:12Amazing!
0:00:12 > 0:00:15That's not just animals that are deadly to me...
0:00:15 > 0:00:17but that are deadly in their own world.
0:00:17 > 0:00:21My crew and I are travelling the planet, and you're coming with me
0:00:21 > 0:00:23every step of the way!
0:00:38 > 0:00:41This time on Deadly 60, we're doing things a little differently.
0:00:41 > 0:00:45We're dealing with one wondrous family of animals
0:00:45 > 0:00:48that comes in all different shapes and sizes.
0:00:48 > 0:00:51We're travelling all over Europe - from up here in the frozen north
0:00:51 > 0:00:55right down to where I live in the UK.
0:00:55 > 0:00:59And what is that one family of animals? I wonder if you can guess.
0:01:01 > 0:01:04That's right - it's the dogs.
0:01:04 > 0:01:08In fact, we're dealing with the whole canine family,
0:01:08 > 0:01:09including their wild ancestors.
0:01:10 > 0:01:13The African hunting dog...
0:01:13 > 0:01:16coyotes...
0:01:16 > 0:01:20and Ethiopian wolves are all superbly adapted for hunting.
0:01:21 > 0:01:25And we live right alongside many millions of these canine carnivores,
0:01:25 > 0:01:30in the shape of the domestic dogs that share our homes.
0:01:31 > 0:01:34There are over 150 different breeds of dog,
0:01:34 > 0:01:38but all descended from one formidable wild force -
0:01:38 > 0:01:39the wolf.
0:01:39 > 0:01:42I'm going to track down some wolves later in the show.
0:01:42 > 0:01:46Before I do, let's check out how some of their deadly attributes
0:01:46 > 0:01:49are mirrored in the dogs we see around us every day.
0:01:50 > 0:01:54I'm going to use dogs to display the uncanny canine capabilities
0:01:54 > 0:01:57I just wouldn't be able to show you with wild wolves.
0:01:59 > 0:02:01We have three sets of working dogs
0:02:01 > 0:02:04to show you their special skills up close.
0:02:04 > 0:02:06Alaskan Huskies,
0:02:06 > 0:02:09a Rottweiler rescue dog
0:02:09 > 0:02:11and a trained police hound.
0:02:15 > 0:02:19We're starting here in Norway, where it's a rather chilly minus 15.
0:02:21 > 0:02:24The breed I'm going to look at first are these huskies.
0:02:24 > 0:02:26They've been bred to work together.
0:02:26 > 0:02:30and just like wolves, they can run for miles.
0:02:30 > 0:02:33they're real specialists and they thrive in the cold.
0:02:36 > 0:02:39HUSKIES WHIMPER
0:02:41 > 0:02:44Amongst working dogs, there's probably nothing that comes closer
0:02:44 > 0:02:48to a pack of wolves than these guys. These are sled dogs -
0:02:48 > 0:02:50specifically Alaskan huskies.
0:02:50 > 0:02:54and look at those beautiful blue eyes.
0:02:54 > 0:02:56Very much like you'd expect to see on a puppy wolf.
0:02:56 > 0:03:03And those HUGE paws - great big, broad plates of meat
0:03:03 > 0:03:05for keeping it up above the snow
0:03:05 > 0:03:07and running at great speeds.
0:03:07 > 0:03:12A pack of wolves spends as much as a third of their time on the move.
0:03:12 > 0:03:13Come on, guys!
0:03:13 > 0:03:17These huskies aren't as big as wolves, but have the same long legs,
0:03:17 > 0:03:20enabling them to lope over vast distances using the minimum energy.
0:03:20 > 0:03:22Here they go!
0:03:22 > 0:03:25It's time to put them to the test.
0:03:27 > 0:03:30These husky dogs have been bred over generations
0:03:30 > 0:03:32for incredible endurance.
0:03:32 > 0:03:36They have big hearts and lungs that can drive them along
0:03:36 > 0:03:40at the same sort of pace as an Olympic sprinter - for hour on hour!
0:03:40 > 0:03:43They can cover as much as 100 miles in a day.
0:03:43 > 0:03:48Out here in the snow, that really is an incredible achievement.
0:03:48 > 0:03:51they just function so well as a team together.
0:03:51 > 0:03:56Just like a pack of wolves, every one of them has their own job
0:03:56 > 0:03:58and they function beautifully as a unit.
0:03:58 > 0:04:01They're just got boundless energy.
0:04:02 > 0:04:05This is such a wonderful experience.
0:04:07 > 0:04:11So huskies have extraordinary stamina, like marathon runners.
0:04:13 > 0:04:16And, like wolves, if they WERE out hunting,
0:04:16 > 0:04:18they'd certainly be able to keep up the chase.
0:04:18 > 0:04:22But a wolf isn't deadly just because of its stamina.
0:04:22 > 0:04:26They're also armed with a sensational sense of smell -
0:04:26 > 0:04:29a trait that dogs have inherited.
0:04:31 > 0:04:34That's enough. Right, you've said hello. It's dead. It's dead.
0:04:34 > 0:04:36Throughout the dog family,
0:04:36 > 0:04:40whether we're talking about wild dogs or domestic dogs,
0:04:40 > 0:04:44there's one canine supersense that's more important than any other.
0:04:44 > 0:04:45It's this.
0:04:45 > 0:04:49The nose and that superb sense of smell.
0:04:49 > 0:04:51This is Sorrow. She's a Rottweiler
0:04:51 > 0:04:55and her sense of smell is thousands of times more effective
0:04:55 > 0:04:57than that of a human being.
0:04:57 > 0:05:01If she was a wolf, she'd use it in the wild to track and locate prey.
0:05:01 > 0:05:04But Sorrow has been trained to put her sense of smell
0:05:04 > 0:05:05to a totally different use.
0:05:05 > 0:05:08- She is a life-saver. - SORROW GROWLS
0:05:08 > 0:05:10HE LAUGHS
0:05:12 > 0:05:15Sorrow's nose is a finely tuned tool.
0:05:15 > 0:05:18She'll be using it to track me down underneath this thick snow.
0:05:22 > 0:05:26If you're walking, climbing or skiing in these mountains,
0:05:26 > 0:05:31by far the most frightening and dangerous thing is avalanches.
0:05:31 > 0:05:34You try and imagine tons of ice and snow
0:05:34 > 0:05:37coming plummeting down out of the hills.
0:05:37 > 0:05:40It's quite easy for a person to get buried alive.
0:05:40 > 0:05:43I can't imagine anything more frightening in the world.
0:05:43 > 0:05:45But I'm about to try it out first hand.
0:05:45 > 0:05:48This is a little Deadly 60 experiment
0:05:48 > 0:05:53and all I've got to save me is Sorrow's magical nose.
0:05:54 > 0:05:59- Hi. guys.- Hello.- Hello. OK. Shall I climb in?- Yep.
0:06:04 > 0:06:07OK, have a got a camera to take in with me?
0:06:09 > 0:06:10Thank you very much.
0:06:10 > 0:06:13OK, guys. This is all a bit scary.
0:06:17 > 0:06:21Let's just hope that that dog's nose is as good as they say.
0:06:21 > 0:06:23Right, bury me, guys!
0:06:31 > 0:06:33They've assured me that I'll be totally safe
0:06:33 > 0:06:35under here in my snow cave.
0:06:35 > 0:06:37But that doesn't make me feel any less nervous,
0:06:37 > 0:06:40as they shovel in the snow, block out the light
0:06:40 > 0:06:41and everything goes quiet.
0:07:00 > 0:07:03OK, so now I'm buried alive...
0:07:03 > 0:07:07which is all pretty spooky and very, very cold.
0:07:07 > 0:07:11Obviously, if this was a real avalanche,
0:07:11 > 0:07:16I wouldn't have any space at all and that would be VERY frightening.
0:07:16 > 0:07:18I hope that dog comes quick.
0:07:21 > 0:07:24Above ground, Sorrow and her handler are brought in,
0:07:24 > 0:07:26but the clock is ticking.
0:07:26 > 0:07:30As avalanches settle, the snow sets hard like concrete,
0:07:30 > 0:07:34so a real victim could be injured, crushed AND out of air.
0:07:34 > 0:07:39So it's down to dogs like Sorrow to save the day.
0:07:39 > 0:07:43Just dying for the sound of some scrabbling paws overhead.
0:07:46 > 0:07:49The dogs are trained to zigzag back and forth,
0:07:49 > 0:07:51trying to pick up the scent of a buried person.
0:07:51 > 0:07:54But Sorrow's got to search this entire hillside.
0:07:59 > 0:08:02A well-trained sniffer dog's nose can distinguish between
0:08:02 > 0:08:04the smell of people who've walked over the snow
0:08:04 > 0:08:09and the faintest trace of a person hidden even ten metres beneath it,
0:08:09 > 0:08:12by searching for human scent drifting up through the snow,
0:08:12 > 0:08:15and then digging down towards the source.
0:08:19 > 0:08:20SORROW BARKS
0:08:25 > 0:08:27SCRATCHING
0:08:27 > 0:08:29I hear something.
0:08:29 > 0:08:31I think I might have been found.
0:08:35 > 0:08:37Dogs use powerful sniffs to draw in smells,
0:08:37 > 0:08:39and the part of their brain that deals with smell
0:08:39 > 0:08:42is much more developed than ours.
0:08:42 > 0:08:44Hey!
0:08:44 > 0:08:50- SORROW BARKS - My saviour! Hello! Look at that!
0:08:51 > 0:08:53Come on, then!
0:08:53 > 0:08:55HE LAUGHS
0:08:55 > 0:08:56Oh, hello!
0:08:58 > 0:08:59Rescue!
0:08:59 > 0:09:00Let's get out.
0:09:07 > 0:09:10Where's my saviour? Come on, then. Come on, then!
0:09:10 > 0:09:12- Come on.- Sit, sit, sit.
0:09:12 > 0:09:15That remarkable nose that's just sniffed me out under the snow
0:09:15 > 0:09:17is exactly the same kind of nose
0:09:17 > 0:09:20as you'll find throughout the dog family.
0:09:20 > 0:09:23On a wolf, it'd be used to track down its prey.
0:09:25 > 0:09:27So imagine not just one nose, but a whole pack
0:09:27 > 0:09:31constantly testing the air for the first whiff of dinner.
0:09:31 > 0:09:38The wolf uses all 220 million of its smell receptors to deadly use.
0:09:38 > 0:09:42So that sensitive canine nose can sniff out its prey,
0:09:42 > 0:09:43but how does it actually catch it?
0:09:43 > 0:09:45THEY LAUGH
0:09:47 > 0:09:51Well, I'm travelling back to the UK to meet a special type of dog that,
0:09:51 > 0:09:55just like its wolf cousin, can unleash a savage bite.
0:09:56 > 0:10:00Avon and Somerset's police force use German shepherds to hunt down
0:10:00 > 0:10:01and catch their criminals.
0:10:01 > 0:10:04I don't want to get bitten by one of these German shepherds -
0:10:04 > 0:10:06they have an incredible bite force.
0:10:06 > 0:10:09So what I'm going to do is cover my arm using this -
0:10:09 > 0:10:11the magic sleeve.
0:10:11 > 0:10:16Up here it's hard, solid plastic and down here it's very heavily padded.
0:10:16 > 0:10:20Hopefully, the dog will head for this, and I won't get bitten.
0:10:20 > 0:10:26I can't pretend for a second that I'm not a little bit scared.
0:10:27 > 0:10:29STEVE LAUGHS
0:10:29 > 0:10:31They love it when I get frightened.
0:10:31 > 0:10:33DOG BARKS
0:10:35 > 0:10:39Right. Now, I have to say that I'm going to be making a lot of noise
0:10:39 > 0:10:42and probably looking like I'm in a lot of pain.
0:10:42 > 0:10:44Don't worry. This is all part of the act.
0:10:44 > 0:10:46I'm pretending that I'm a criminal -
0:10:46 > 0:10:48I have to play that role right through,
0:10:48 > 0:10:50otherwise the dog won't do his job.
0:10:50 > 0:10:54OK. Nerves are rising a little bit, as is my heartbeat.
0:10:54 > 0:10:55Let's get started.
0:10:55 > 0:10:57OK, Justin! Let's go.
0:10:57 > 0:10:59Justin is a police dog handler
0:10:59 > 0:11:02and has been training his dog, Nero, for several years.
0:11:02 > 0:11:05'I've got a mini camera in my left hand,
0:11:05 > 0:11:07'so I hope he goes for the padded arm.'
0:11:07 > 0:11:09- NERO SNARLS - Come on! Come on!
0:11:09 > 0:11:11I won't tell you again - stay there and calm down!
0:11:11 > 0:11:14Come on! Come on! Come on! Ahhhh!
0:11:14 > 0:11:17Ahhh! Ahhh! Ahh!
0:11:17 > 0:11:19Ooh!
0:11:19 > 0:11:21NERO GROWLS AND SNARLS
0:11:26 > 0:11:27Whoa!
0:11:27 > 0:11:30- Good boy, Nero!- That was amazing!
0:11:30 > 0:11:33Ah! Come on, then! Oh.
0:11:33 > 0:11:36He's SO strong!
0:11:36 > 0:11:38you can see, despite the fact that he's half my weight,
0:11:38 > 0:11:42he uses it so effectively by bracing back with his legs
0:11:42 > 0:11:46and using his whole body to clamp down and drag with those jaws.
0:11:46 > 0:11:51- OK, Justin, I think he can come off now.- Right. Criminal stand still!
0:11:51 > 0:11:52Nero, right!
0:11:52 > 0:11:55He-he-hey! Good boy!
0:11:55 > 0:11:56Good lad!
0:11:56 > 0:11:59- Good boy!- How's about that?
0:11:59 > 0:12:04From a raging morass of teeth
0:12:04 > 0:12:10just completely quietened down by one single word from his trainer.
0:12:10 > 0:12:12THAT is incredible intelligence.
0:12:12 > 0:12:15When he's off duty, Nero is the family pet at home.
0:12:15 > 0:12:20Justin's training secret is to have Nero's favourite toy with him,
0:12:20 > 0:12:24so as soon as he calls, Nero will stop his attack and run off to play.
0:12:24 > 0:12:28These bite experiments are crucial for keeping the dogs fit
0:12:28 > 0:12:30and well practised for their police work.
0:12:30 > 0:12:32But you can tell Nero loves it.
0:12:32 > 0:12:33Wow!
0:12:33 > 0:12:37you certainly wouldn't want to get on the wrong side of one of those!
0:12:39 > 0:12:40Ooh!
0:12:40 > 0:12:42NERO GROWLS
0:12:44 > 0:12:47The raw aggression shown by police dogs
0:12:47 > 0:12:49stems from the hunting instincts of wolves,
0:12:49 > 0:12:53whose interlocking teeth can grip and hang onto struggling prey.
0:12:53 > 0:12:56So, now we've seen the skills of our working dogs,
0:12:56 > 0:12:58all experts at running,
0:12:58 > 0:13:00sniffing
0:13:00 > 0:13:03or biting...
0:13:03 > 0:13:07but the wolf is a pro at all three.
0:13:07 > 0:13:10And now it's time to try and find one in the wild.
0:13:10 > 0:13:11We're heading to Romania.
0:13:14 > 0:13:18Travelling in style, we're heading to a beautiful wildlife reserve
0:13:18 > 0:13:20in the Carpathian Mountains.
0:13:20 > 0:13:24- Comfy there, mate?- Yeah, I'm all right. Are you?- Yeah, perfect.
0:13:26 > 0:13:30Romania's home to Europe's largest population of grey wolves.
0:13:30 > 0:13:34Local researchers have several hides set up in secret locations
0:13:34 > 0:13:35throughout the forests.
0:13:35 > 0:13:41This gives us our best chance for a real wild encounter.
0:13:42 > 0:13:47Our mission to see a wild wolf is, well, a real mission.
0:13:47 > 0:13:51In fact, there's probably nothing we've ever done on the Deadly 60
0:13:51 > 0:13:55that's required more patience and more attention to detail.
0:13:55 > 0:13:57Come with me.
0:14:03 > 0:14:05- You all right?- Yep.
0:14:11 > 0:14:15And there's evidence here that these woods are home to other carnivores,
0:14:15 > 0:14:16as well as wolves.
0:14:16 > 0:14:20This here is where a bear has come in the night,
0:14:20 > 0:14:25smelt food inside and scraped down here with its claws.
0:14:25 > 0:14:28But that's nothing. Wait till you see inside.
0:14:33 > 0:14:34Look at that!
0:14:34 > 0:14:37A brown bear actually got in through there,
0:14:37 > 0:14:41just bit away at the floorboards, climbed up. Scary stuff.
0:14:41 > 0:14:44I hope that doesn't happen tonight.
0:14:45 > 0:14:46OK...
0:14:46 > 0:14:49This bed here, that's where someone can grab some shut-eye
0:14:49 > 0:14:51when they're not on nightwatch duty.
0:14:51 > 0:14:54That's my seat and this here...
0:14:54 > 0:14:58is the infra-red camera which means that Johnny can film even in total darkness.
0:14:58 > 0:15:05And out there is the clearing where we are hoping to see our wolves.
0:15:05 > 0:15:09We've put down some old, rotting, smelly meat
0:15:09 > 0:15:14and the wolves should pick up the scent from miles away. I can smell it from here.
0:15:14 > 0:15:17There's also a small camera but I'm not going to go out there now
0:15:17 > 0:15:20because my scent could drive the wolves away.
0:15:21 > 0:15:24From here on in, it's just a waiting game.
0:15:26 > 0:15:28WOLVES HOWL
0:15:28 > 0:15:31So with all of our night-vision camera gear in place,
0:15:31 > 0:15:34we get settled into the hide and start the long wait.
0:15:36 > 0:15:40Once the sun goes down, the temperature plummets.
0:15:40 > 0:15:46It's pretty dark outside now. All you can see with the naked eye, are shapes and shadows.
0:15:46 > 0:15:53But we've got Johnny's infra-red camera here and I've a little monitor
0:15:53 > 0:15:56so I should be able to see everything that he can see through the camera,
0:15:56 > 0:16:01now it's just a question of sitting tight, keeping quiet,
0:16:01 > 0:16:05and waiting for some sign of our wolves.
0:16:09 > 0:16:12But it wasn't a wolf that first emerged from the shadows.
0:16:14 > 0:16:16There's something moving there.
0:16:16 > 0:16:18There! There, there, there!
0:16:18 > 0:16:20It's a bear.
0:16:20 > 0:16:22Can you see that, Johnny?
0:16:24 > 0:16:26It's a brown bear.
0:16:29 > 0:16:30Wow!
0:16:30 > 0:16:36This is a young male. He's not fully grown yet but you can still see
0:16:36 > 0:16:41the large hump at the shoulder, much bigger in males.
0:16:44 > 0:16:49This is wonderful for us, the brown bear is an old favourite of the Deadly 60.
0:16:49 > 0:16:52But it's not great news in our search for wolves.
0:16:52 > 0:16:57Wolves and bears don't tend to tolerate each other at food.
0:16:57 > 0:17:03So while he's here the chances of wolves turning up are very slight.
0:17:06 > 0:17:09The bear's been attracted to our rotten meat.
0:17:09 > 0:17:12He steals a chunk and heads off.
0:17:12 > 0:17:16With the bear gone, there's still a chance a wolf may appear.
0:17:25 > 0:17:30But after the early excitement of the bear's visit, the night grows longer and colder.
0:17:32 > 0:17:35Several hours later, I spot something on the monitor.
0:17:38 > 0:17:40Oh, hang on!
0:17:40 > 0:17:42There's something moving in the trees.
0:17:42 > 0:17:47Can you see that? It's a wolf.
0:17:47 > 0:17:50It's definitely a wolf.
0:17:50 > 0:17:51Can you see him?
0:17:51 > 0:17:53There, yes, yes, yes.
0:17:58 > 0:18:03Oh, no! He's carrying his front left foot.
0:18:03 > 0:18:05Can you see that? He's lame.
0:18:10 > 0:18:17It's a little after midnight, our first wolf has come in to investigate the food.
0:18:18 > 0:18:23Unfortunately he's got a bad left foot...
0:18:24 > 0:18:28The front left paw is damaged, he's carrying it quite badly.
0:18:31 > 0:18:35He's just nosing around... in the food.
0:18:37 > 0:18:41He's always on the lookout for potential threats around him.
0:18:41 > 0:18:43It may seem unusual that he's on his own,
0:18:43 > 0:18:48but actually wolves can be solitary for large periods of their lives.
0:18:48 > 0:18:51They don't spend all their time in packs.
0:18:54 > 0:18:58Just have to hope that paw's going to get better.
0:18:58 > 0:19:02Cos he's really going to struggle to hunt like that.
0:19:02 > 0:19:06'But the fact he's feeding tonight means he's got a much better chance of recovery.'
0:19:08 > 0:19:12To see a wild wolf in the forests of Transylvania,
0:19:12 > 0:19:15I just cannot tell you enough
0:19:15 > 0:19:19what a privilege this experience is.
0:19:19 > 0:19:21Absolutely remarkable.
0:19:21 > 0:19:24It's such a shame that he's injured.
0:19:24 > 0:19:29'After snuffling around the food, our wolf vanishes as quietly as he arrived,
0:19:29 > 0:19:35'giving us just the briefest, fleeting glimpse of a truly wild predator.'
0:19:41 > 0:19:46From Romania, we travel much farther north to a rather snowy Norway.
0:19:47 > 0:19:50The wolves here at Polar Zoo give us an incredible opportunity to get
0:19:50 > 0:19:51a much closer look.
0:19:51 > 0:19:57So wolves are one of the hardest animals in the whole world to encounter in the wild.
0:19:57 > 0:19:59But I do have a trick up my sleeve.
0:19:59 > 0:20:02We're actually now in the Arctic Circle in Norway,
0:20:02 > 0:20:07and behind this fence is a group of wolves that's kind of used to people.
0:20:07 > 0:20:11I've also got Tess here who's going to watch my back.
0:20:11 > 0:20:13She's going to be my bodyguard. Hi, Tess.
0:20:13 > 0:20:15- Hello.- Hi!- Are you ready?
0:20:15 > 0:20:17Absolutely, I think so!
0:20:17 > 0:20:18Let's go on in.
0:20:21 > 0:20:22Come in.
0:20:22 > 0:20:27I have to say now, these are not tame animals.
0:20:27 > 0:20:31They're still wolves so we need to watch our back at all times
0:20:31 > 0:20:34and just keep an eye on them.
0:20:34 > 0:20:38Beyond that fence...look at that!
0:20:42 > 0:20:44It's like coming into Jurassic Park.
0:20:44 > 0:20:49Absolutely huge fences and gates but these are such canny animals,
0:20:49 > 0:20:51they would escape if there was anything less.
0:20:54 > 0:20:56Here they come!
0:20:57 > 0:20:58Here we go.
0:20:58 > 0:21:00All right... Come on, puppies!
0:21:04 > 0:21:07Tess has been interacting with them since they were puppies,
0:21:07 > 0:21:11but it's not going to be the same with us, particularly with the camera equipment.
0:21:11 > 0:21:13WOLVES WHINE
0:21:13 > 0:21:17By studying these socialised wolves up close, Tess and her team
0:21:17 > 0:21:21are learning all about their body language and how they communicate.
0:21:21 > 0:21:22< Now, if we sit down...
0:21:27 > 0:21:32OK, I think this is typical.
0:21:32 > 0:21:37Why wolves are so misunderstood and difficult to encounter in the wild.
0:21:37 > 0:21:42They're obviously really inquisitive, they want to check out this new thing in their environment,
0:21:42 > 0:21:46but at the same time they are very careful and cautious.
0:21:46 > 0:21:49They don't want to come close to anything that could be dangerous.
0:21:49 > 0:21:53Things are very different when there's prey around.
0:21:55 > 0:21:59Wolves hunt large animals like deer that can be up to five times their body size,
0:21:59 > 0:22:03and well-armed with sharp hooves and antlers.
0:22:03 > 0:22:09The incredible stamina of wolves, to run for miles and miles when chasing down prey
0:22:09 > 0:22:13means that when they've locked onto a target, they mean business.
0:22:14 > 0:22:19Wolves have keen hunting instincts and will pick off any animal that breaks away from the herd,
0:22:19 > 0:22:21bringing it down with powerful jaws,
0:22:21 > 0:22:25aggressive bites and co-ordinated teamwork.
0:22:28 > 0:22:33But it's when the wolves have made a kill that the pecking order in the pack lets you see who's boss.
0:22:35 > 0:22:38The top dog gets the pick of the best bits
0:22:38 > 0:22:41and makes sure everyone knows who's boss.
0:22:43 > 0:22:49'But without the lure of food, these wolves are taking their time to get used to the crew and me.'
0:22:49 > 0:22:52This is really interesting.
0:22:53 > 0:22:56As they're approaching, they're kind of chatting to each other.
0:22:56 > 0:23:03Just figuring out who's going to be the first to be allowed to come in and talk to Tess, not to me.
0:23:11 > 0:23:13Hello! Hello!
0:23:13 > 0:23:15Wow!
0:23:17 > 0:23:21OK. Now they're starting to build up their confidence.
0:23:22 > 0:23:27They're still playing around with each other, still definitely some nerves going on.
0:23:28 > 0:23:32The fighting and nipping and scratching and biting, it all has a real function
0:23:32 > 0:23:36of keeping the team together and everyone in their right positions.
0:23:36 > 0:23:39It also gives you a really good look at those teeth.
0:23:43 > 0:23:45The canines are huge.
0:23:46 > 0:23:48Utterly ferocious!
0:23:49 > 0:23:53'Wolves have a bite twice as strong as our German Shepherd police dog.
0:23:55 > 0:24:00'Tess knows each wolf from their different personalities. As they come closer,
0:24:00 > 0:24:02'they greet her by licking her face.
0:24:03 > 0:24:07'Although they might seem very much like domestic dogs,
0:24:07 > 0:24:11'these wolves are still wild animals and our movements must be slow and cautious.'
0:24:15 > 0:24:21As they approach, they're very much being led by that canine supersense,
0:24:21 > 0:24:23smell.
0:24:23 > 0:24:25Let's see what comes in first.
0:24:26 > 0:24:29Always the nose, always sussing things out
0:24:29 > 0:24:32with that incredible sense of smell first.
0:24:32 > 0:24:352,000 times more powerful than ours.
0:24:38 > 0:24:43'That phenomenal sense of smell is used to track prey from over a mile away in the wild.'
0:24:45 > 0:24:51They're gradually starting to get more and more confident, checking out Nick, the soundman,
0:24:51 > 0:24:52and Johnny, the cameraman,
0:24:52 > 0:24:55getting closer and closer.
0:24:57 > 0:25:01But as they approach, I mustn't let myself forget how deadly these animals are.
0:25:01 > 0:25:04And the wolves are quick to remind me who's in charge.
0:25:04 > 0:25:06Go on, look...
0:25:07 > 0:25:08Ow!
0:25:08 > 0:25:12I think I might have moved a little bit too fast there,
0:25:12 > 0:25:14and just got snapped at.
0:25:19 > 0:25:22Just to show that there's nothing in my hands.
0:25:28 > 0:25:34Wow. Just a nibble...but even so.
0:25:34 > 0:25:37As individuals, wolves are awesome predators,
0:25:37 > 0:25:41but it's when they come together as a pack that they are really deadly.
0:25:41 > 0:25:46The way they bring themselves together, particularly before a hunt, is using a howl,
0:25:46 > 0:25:50and we're going to try that now and see if we can get these guys to join in.
0:25:51 > 0:25:53- Shall we give it a go?- Give it a go.
0:25:53 > 0:25:56THEY HOWL
0:26:04 > 0:26:07WOLVES HOWL
0:26:07 > 0:26:08It's working!
0:26:17 > 0:26:21'The howl can be heard by other wolves over six miles away
0:26:21 > 0:26:25'and also acts as a warning signal to rival packs to stay away.'
0:26:28 > 0:26:34And what a wonderful, eerie, chilling stunning sound!
0:26:34 > 0:26:37CHORUS OF HOWLS
0:26:37 > 0:26:43The wolf. The voice of the wilderness and the ultimate team hunter.
0:26:43 > 0:26:47Definitely on the Deadly 60.
0:26:49 > 0:26:53Wolves use their phenomenal sense of smell to sniff out their prey,
0:26:53 > 0:26:57then run it down with extraordinary stamina,
0:26:57 > 0:27:00before using raw aggression to go in for the kill.
0:27:02 > 0:27:06Wolves have secured a place on the Deadly 60.
0:27:11 > 0:27:14This is the most work my crew have done in ages!
0:27:14 > 0:27:18'Join me next time as we look for more deadly animals up in the snowy north.'
0:27:18 > 0:27:21BEAST SNORTS
0:27:19 > 0:27:21That's pretty scary stuff!
0:27:21 > 0:27:23Are we going to see it...?
0:27:23 > 0:27:24Wow!
