My name is Steve Backshall. | 0:00:02 | 0:00:03 | |
People call me Steve. | 0:00:04 | 0:00:06 | |
I'm on a mission to find the Deadly 60. | 0:00:09 | 0:00:12 | |
'That's 60 deadly creatures from around the world. | 0:00:12 | 0:00:17 | |
'And you're coming with me every step of the way.' | 0:00:17 | 0:00:19 | |
Ow! | 0:00:20 | 0:00:22 | |
'Time to hit the trail and see what animals are worthy of making it | 0:00:29 | 0:00:32 | |
'onto my Deadly 60.' | 0:00:32 | 0:00:35 | |
We're here, in Arizona's Sonoran Desert. | 0:00:35 | 0:00:38 | |
'This is the hottest area of the USA, | 0:00:39 | 0:00:41 | |
'with temperatures getting to over 50 degrees. | 0:00:41 | 0:00:44 | |
'But deadly environments go hand in hand with deadly animals. | 0:00:44 | 0:00:48 | |
'We're in the right place.' | 0:00:48 | 0:00:50 | |
It may get ridiculously hot here, | 0:00:50 | 0:00:52 | |
but it's not as bleak or unforgiving as many deserts in the world, | 0:00:52 | 0:00:56 | |
and there's loads of wildlife here. | 0:00:56 | 0:00:58 | |
In amongst these plants are plenty of ground squirrels, rats, rabbits, | 0:00:58 | 0:01:03 | |
all sorts of potential prey for predators. | 0:01:03 | 0:01:06 | |
But they're very fast and very elusive. | 0:01:06 | 0:01:08 | |
That's not a problem, though, for the birds of prey, | 0:01:08 | 0:01:11 | |
masters of the sky here by day - and by night. | 0:01:11 | 0:01:15 | |
'And I'll need a bird of the night | 0:01:15 | 0:01:18 | |
'to call in my next deadly contender.' | 0:01:18 | 0:01:21 | |
This impossibly beautiful creature | 0:01:21 | 0:01:24 | |
is one of the fiercest predators found around here. | 0:01:24 | 0:01:28 | |
It's a Great Horned Owl. | 0:01:28 | 0:01:31 | |
And though she might just look very pretty, | 0:01:31 | 0:01:34 | |
if you're a small mammal running through these bushes, | 0:01:34 | 0:01:37 | |
this would be your living nightmare. | 0:01:37 | 0:01:40 | |
Those horns which give it its name aren't actually ears at all. | 0:01:40 | 0:01:45 | |
Those are just tufts of feathers. | 0:01:45 | 0:01:47 | |
The ears are actually located... | 0:01:47 | 0:01:49 | |
I'm a bit nervous about showing you this cos I might lose a finger, | 0:01:49 | 0:01:53 | |
but just round to the side of the eyes, | 0:01:53 | 0:01:56 | |
those dark shapes actually mark the ears. | 0:01:56 | 0:02:00 | |
One is slightly higher than the other on each side of the head. | 0:02:00 | 0:02:04 | |
So when you see an owl doing this - | 0:02:04 | 0:02:06 | |
that very distinctive movement - | 0:02:06 | 0:02:08 | |
it's figuring out what's happening around it | 0:02:08 | 0:02:11 | |
by the sounds that are coming in and their relationship to the ears. | 0:02:11 | 0:02:14 | |
SQUAWKS | 0:02:14 | 0:02:15 | |
'I'm hoping that this bird will act as a sort of a lure.' | 0:02:15 | 0:02:19 | |
There's another bird which flies mostly during the daytime | 0:02:19 | 0:02:23 | |
and is the sworn enemy of the Great Horned Owl, | 0:02:23 | 0:02:27 | |
and it's this bird I want to put on the Deadly 60. | 0:02:27 | 0:02:31 | |
Just from this owl calling, | 0:02:31 | 0:02:33 | |
one of them has come and landed over there. | 0:02:33 | 0:02:36 | |
And there's actually another one coming in to join it now. | 0:02:36 | 0:02:39 | |
It's a Harris Hawk. | 0:02:39 | 0:02:41 | |
They're one of the most common birds of prey here | 0:02:43 | 0:02:45 | |
and the absolute sworn enemy of the Great Horned Owl. | 0:02:45 | 0:02:49 | |
Look at this! | 0:02:49 | 0:02:51 | |
Look at our lady here. She's absolutely fixed on them. | 0:02:51 | 0:02:54 | |
This is one of the most profound hatreds you'll find | 0:02:56 | 0:03:01 | |
in the whole of the Sonoran Desert. | 0:03:01 | 0:03:03 | |
At night-time, the Great Horned Owl will take on, catch and kill a Harris Hawk. | 0:03:03 | 0:03:08 | |
But in the day, Harris Hawks have something remarkable on their side. | 0:03:08 | 0:03:12 | |
-They work together as a team. -SCREECH | 0:03:12 | 0:03:14 | |
And there's two of them sat in the trees right behind me | 0:03:14 | 0:03:18 | |
watching this little lady. | 0:03:18 | 0:03:21 | |
They're probably thinking about ganging up on her. | 0:03:21 | 0:03:24 | |
'Harris Hawks may have the standard issue for birds of prey - | 0:03:24 | 0:03:27 | |
'they've got lethal talons, razor-sharp beaks | 0:03:27 | 0:03:30 | |
'and a fast, powerful strike. | 0:03:30 | 0:03:32 | |
'But weapons aren't everything. | 0:03:32 | 0:03:35 | |
'These guys have another trick up their sleeves | 0:03:36 | 0:03:39 | |
'which truly warrants them a place on my Deadly 60. | 0:03:39 | 0:03:44 | |
'Time to take a closer look at this incredible bird.' | 0:03:47 | 0:03:51 | |
Look at that! | 0:03:51 | 0:03:53 | |
Isn't that magnificent? | 0:03:53 | 0:03:55 | |
Obviously this isn't a wild Harris Hawk. | 0:03:55 | 0:03:58 | |
You'd never get one of those to fly onto your fist like this. | 0:03:58 | 0:04:01 | |
This is a falconry bird, | 0:04:01 | 0:04:03 | |
and this is the absolute classic hawk shape. | 0:04:03 | 0:04:05 | |
In fact, as she came in to land on my fist, what you'd have seen | 0:04:05 | 0:04:09 | |
is pretty much exactly the last thing a small mammal would see | 0:04:09 | 0:04:12 | |
before meeting its end. | 0:04:12 | 0:04:14 | |
The way she stopped, throwing her wings back, spreading her tail, | 0:04:14 | 0:04:18 | |
stopped her almost instantly from flight at probably 30, maybe 40mph. | 0:04:18 | 0:04:22 | |
But the most remarkable thing about this bird of prey | 0:04:22 | 0:04:25 | |
is that, while most birds of prey tend to be solitary, | 0:04:25 | 0:04:29 | |
Harris Hawks are very social animals. | 0:04:29 | 0:04:31 | |
In fact, they hunt with their friends. | 0:04:31 | 0:04:34 | |
'Like all good teams, each player has got a job to do. | 0:04:35 | 0:04:40 | |
'We've got a little experiment to show this deadly squad in action.' | 0:04:40 | 0:04:44 | |
So, we have... | 0:04:46 | 0:04:48 | |
one, two, three Harris Hawks, all primed and ready. | 0:04:48 | 0:04:55 | |
Now let's see if we can show you them hunting. | 0:04:55 | 0:04:58 | |
I've got this leather lure, which they're trained to chase, | 0:05:00 | 0:05:04 | |
and I'm gonna hide it in here. | 0:05:04 | 0:05:06 | |
They'll still see it. They have, after all, got "eyes like a hawk". | 0:05:06 | 0:05:11 | |
We'll see what happens. | 0:05:11 | 0:05:14 | |
I'm gonna get as far away as humanly possible. | 0:05:14 | 0:05:18 | |
OK. | 0:05:18 | 0:05:19 | |
There you go. | 0:05:27 | 0:05:29 | |
Agh! They're all going for me! | 0:05:29 | 0:05:31 | |
'Bird one is the frontrunner, | 0:05:31 | 0:05:34 | |
'flushing the prey from cover, | 0:05:34 | 0:05:35 | |
'setting up the kill for the next two.' | 0:05:35 | 0:05:39 | |
And bam! In they go together. | 0:05:39 | 0:05:41 | |
All three birds hit that lure within a couple of seconds. | 0:05:41 | 0:05:45 | |
Imagine if you were a rabbit being hit by not just one bird of death, but three! | 0:05:45 | 0:05:49 | |
You wouldn't stand a chance. | 0:05:49 | 0:05:52 | |
Now they should, | 0:05:52 | 0:05:54 | |
if things go to plan, | 0:05:54 | 0:05:56 | |
share the food a bit. | 0:05:58 | 0:06:00 | |
Come on, guys! Leave some for your friends. | 0:06:00 | 0:06:03 | |
SCREECHING | 0:06:03 | 0:06:05 | |
Scientists believe that when Harris Hawks work together as a group, | 0:06:05 | 0:06:09 | |
they're more than twice as effective at catching prey | 0:06:09 | 0:06:12 | |
than on their own. | 0:06:12 | 0:06:14 | |
For that reason alone, the Harris Hawk makes it onto the Deadly 60. | 0:06:14 | 0:06:18 | |
SCREECHING | 0:06:18 | 0:06:21 | |
'Speed, agility and lethal talons | 0:06:22 | 0:06:24 | |
'are always on hand with birds of prey. | 0:06:24 | 0:06:27 | |
'But it's their precision teamwork | 0:06:27 | 0:06:29 | |
'that gets the Harris Hawk onto the Deadly 60.' | 0:06:29 | 0:06:32 | |
'It's close to midday and temperatures are soaring, | 0:06:40 | 0:06:42 | |
'but we're on the road again | 0:06:42 | 0:06:44 | |
'on the search for our next deadly animal.' | 0:06:44 | 0:06:48 | |
This is the extreme south of the Sonoran Desert. | 0:06:50 | 0:06:53 | |
If I kept going in that direction for 10-15 miles, I'd be in Mexico. | 0:06:53 | 0:06:57 | |
It's a real, full-on, rocky wilderness. | 0:06:57 | 0:07:00 | |
Perfect habitat for the magnificent big cat we're hoping to find. | 0:07:00 | 0:07:04 | |
It's found throughout North and South America | 0:07:04 | 0:07:07 | |
and goes by many different names: | 0:07:07 | 0:07:09 | |
the puma, the cougar, | 0:07:09 | 0:07:11 | |
and here, the mountain lion. | 0:07:11 | 0:07:13 | |
'Mountain lions are such secretive creatures | 0:07:14 | 0:07:17 | |
'that to see one hunting is almost unheard of. | 0:07:17 | 0:07:20 | |
'Just catching a glimpse of one during the day is a privilege. | 0:07:20 | 0:07:23 | |
'So how do we know they're deadly? | 0:07:23 | 0:07:25 | |
'Well, firstly, by looking at their closest cousins. | 0:07:25 | 0:07:30 | |
'And secondly, by the evidence they leave from their deadly deeds, | 0:07:32 | 0:07:36 | |
'taking livestock, deer, | 0:07:36 | 0:07:38 | |
'even attacking the odd person. | 0:07:38 | 0:07:41 | |
'Their secretive ways certainly won't make them any easier to find. | 0:07:41 | 0:07:45 | |
'We're heading deep into one of the many canyons found here. | 0:07:50 | 0:07:53 | |
'My guide is Emil, who's an expert at tracking the mountain lion.' | 0:07:53 | 0:07:59 | |
These tight canyon walls really help focus the cat's movements | 0:07:59 | 0:08:04 | |
into a narrow and predictable spot. | 0:08:04 | 0:08:08 | |
And that's the kind of place we're looking for to set a trail camera, | 0:08:08 | 0:08:12 | |
where everything moving through this canyon has to pass. | 0:08:12 | 0:08:17 | |
This just could not be more classic mountain lion territory. | 0:08:17 | 0:08:22 | |
Just imagine seeing a cat wander out over those rocks. | 0:08:22 | 0:08:26 | |
Fingers crossed. | 0:08:26 | 0:08:28 | |
'Emil works on a project that records and studies the lions in this area. | 0:08:33 | 0:08:37 | |
'And they do this using some very clever camera technology. | 0:08:37 | 0:08:41 | |
'Cameras are hidden and take a picture of anything that moves in front of it. | 0:08:41 | 0:08:45 | |
'The question is: Has it captured an image of a mountain lion?' | 0:08:45 | 0:08:48 | |
Let's see what we got. | 0:08:48 | 0:08:50 | |
This is an infrared flash, | 0:08:52 | 0:08:55 | |
and it's actually taking a video clip | 0:08:55 | 0:08:58 | |
immediately after the photograph is taken. | 0:08:58 | 0:09:01 | |
-What is that? -Peccary. -No. | 0:09:01 | 0:09:04 | |
-It's not a razorback, is it? -It's a black bear. | 0:09:04 | 0:09:07 | |
No! | 0:09:07 | 0:09:09 | |
-A nice, big, beautiful black bear. -Wow! | 0:09:09 | 0:09:12 | |
What a great shot! | 0:09:12 | 0:09:14 | |
Oh, there's the Coues deer, the white-tailed deer. | 0:09:14 | 0:09:18 | |
-Argh! -There he is. | 0:09:21 | 0:09:23 | |
Fantastic! Look at that! | 0:09:23 | 0:09:26 | |
Look at that beautiful cat. | 0:09:26 | 0:09:28 | |
Oh, that is absolutely wonderful! | 0:09:28 | 0:09:31 | |
This animal ran through | 0:09:31 | 0:09:33 | |
-right where I'm sitting now. -Exactly where we're sitting, yeah. | 0:09:33 | 0:09:37 | |
EMIL CHUCKLES | 0:09:37 | 0:09:39 | |
-Wow! -Do you know what that is? | 0:09:39 | 0:09:41 | |
It looks like... I'm not gonna say. It looks like a cat | 0:09:41 | 0:09:44 | |
-just coming right down towards the front of the lens. -Absolutely. | 0:09:44 | 0:09:48 | |
Unfortunately the face is just out of the frame. | 0:09:48 | 0:09:51 | |
-But it'll be on the video. -We'll have a video of this one. | 0:09:51 | 0:09:56 | |
Oh! Look at that! | 0:09:56 | 0:09:59 | |
-Wonderful! -All right. | 0:09:59 | 0:10:02 | |
EMIL CHUCKLES | 0:10:02 | 0:10:04 | |
And she was here at 3:20 in the afternoon. | 0:10:04 | 0:10:09 | |
-Broad daylight. -It's quarter to three right now. | 0:10:09 | 0:10:12 | |
Well, if we sit here long enough, you never know. | 0:10:12 | 0:10:16 | |
If we sit here long enough, one will walk by. | 0:10:16 | 0:10:18 | |
-Well, we saw a couple of lions. -Great stuff! | 0:10:18 | 0:10:21 | |
That's absolutely fantastic! | 0:10:21 | 0:10:23 | |
Can you believe they were walking here in the middle of the day? | 0:10:23 | 0:10:26 | |
Yeah, now that I'd like to see. | 0:10:26 | 0:10:28 | |
PURRING | 0:10:30 | 0:10:32 | |
Our mission to find a mountain lion has taken a really exciting twist. | 0:10:33 | 0:10:37 | |
Local biologists have tracked one particular mountain lion | 0:10:37 | 0:10:40 | |
that's been ranging through hundreds of miles of mountains. | 0:10:40 | 0:10:43 | |
But today they've got to try and capture it. | 0:10:43 | 0:10:46 | |
This could be our perfect opportunity to get right up close to a mountain lion. | 0:10:46 | 0:10:51 | |
'The scientists want to catch the lion to remove a tracking collar | 0:10:51 | 0:10:55 | |
'holding information about its movements for the last six months.' | 0:10:55 | 0:11:01 | |
All this modern technology, and our best chance of finding a lion | 0:11:01 | 0:11:05 | |
is old-fashioned tracking. | 0:11:05 | 0:11:07 | |
These dogs have been trained to pick up the scent of a mountain lion. | 0:11:07 | 0:11:11 | |
They're wearing GPS collars so we know exactly where they go. | 0:11:11 | 0:11:15 | |
With a bit of luck, they'll lead us straight to the lion. | 0:11:15 | 0:11:19 | |
They're looking very excited. | 0:11:19 | 0:11:22 | |
Good luck, guys! | 0:11:22 | 0:11:23 | |
'These sniffer dogs will follow the scent of the lion, | 0:11:23 | 0:11:26 | |
'and, like a domestic cat avoiding a dog, | 0:11:26 | 0:11:29 | |
'the lion will climb a tree when they get close. | 0:11:29 | 0:11:33 | |
'The dogs will then wait at the base of the tree | 0:11:33 | 0:11:35 | |
'until the scientists arrive to capture the animal. | 0:11:35 | 0:11:38 | |
'Without the dogs, the lion would just keep running | 0:11:38 | 0:11:41 | |
'and the team wouldn't stand a chance of getting near it. | 0:11:41 | 0:11:45 | |
'A mountain lion could cover a huge area in search of food - | 0:11:50 | 0:11:53 | |
'up to 100 square miles. | 0:11:53 | 0:11:56 | |
'And in this kind of habitat, | 0:11:56 | 0:11:58 | |
'that's a whole lot of holes to hide in.' | 0:11:58 | 0:12:01 | |
VOICES OVER RADIO | 0:12:04 | 0:12:06 | |
Just had the most amazing call on the radio. | 0:12:06 | 0:12:08 | |
The guys with the hounds have located the lion. | 0:12:08 | 0:12:11 | |
They think it's coming down the dry river bed we're on now, right towards us. | 0:12:11 | 0:12:15 | |
VOICES OVER RADIO | 0:12:15 | 0:12:18 | |
It's all going off on the rocks ahead of us. | 0:12:21 | 0:12:23 | |
-DOGS BARKING -The dogs are going mad. | 0:12:23 | 0:12:26 | |
It looks like the lion's gone into a hole somewhere in these rocks. | 0:12:26 | 0:12:30 | |
VOICES OVER RADIO | 0:12:32 | 0:12:35 | |
DOGS HOWL | 0:12:45 | 0:12:46 | |
Where do we think the lion is? | 0:12:46 | 0:12:49 | |
-This hole right here. -We can't get up. | 0:12:49 | 0:12:51 | |
We're trying to get up in there and look in. | 0:12:51 | 0:12:54 | |
'There's only one thing to do: | 0:12:54 | 0:12:56 | |
'in order to see if there's a lion up there, | 0:12:56 | 0:12:58 | |
'I'll have to climb up very carefully | 0:12:58 | 0:13:01 | |
'and have a closer look.' | 0:13:01 | 0:13:03 | |
-Can you see the end of it? -Well... | 0:13:10 | 0:13:13 | |
There definitely has been a cat in here very recently. | 0:13:13 | 0:13:18 | |
Steve, does that thing go on back up in there or not? | 0:13:18 | 0:13:22 | |
No. Doesn't seem to. | 0:13:22 | 0:13:25 | |
It stops here. | 0:13:26 | 0:13:27 | |
All of a sudden, with everything going crazy | 0:13:32 | 0:13:34 | |
and us being certain that we had our mountain lion, | 0:13:34 | 0:13:39 | |
total silence. | 0:13:39 | 0:13:41 | |
The trail's gone cold. | 0:13:41 | 0:13:43 | |
It seems like the cat's managed to get out of the canyon and head off into the distance, | 0:13:43 | 0:13:48 | |
so our chances of finding it now are slim to none. | 0:13:48 | 0:13:52 | |
But we came this close. | 0:13:52 | 0:13:54 | |
Anyway, despite the fact that we didn't quite make it, | 0:13:55 | 0:13:58 | |
there has to be no doubt that a cat this beautiful that manages to range throughout the Americas | 0:13:58 | 0:14:04 | |
so strong, so powerful, | 0:14:04 | 0:14:06 | |
it's got to be on the Deadly 60. | 0:14:06 | 0:14:07 | |
'Whether we've seen one in the flesh or not, | 0:14:09 | 0:14:12 | |
'this awesome predator, | 0:14:12 | 0:14:13 | |
'capable of avoiding dogs, horses, trackers, and this camera crew, | 0:14:13 | 0:14:19 | |
'has certainly got to go on the Deadly 60.' | 0:14:19 | 0:14:23 | |
Despite what many people think about deserts being alive with snakes, | 0:14:28 | 0:14:33 | |
they can be quite shy of people and often very hard to find. | 0:14:33 | 0:14:39 | |
Luckily, though, we've got some Deadly 60 technology on our side. | 0:14:39 | 0:14:43 | |
Matt, talk us through how this works. | 0:14:45 | 0:14:47 | |
This antenna's directional, | 0:14:47 | 0:14:49 | |
so it'll tell you the strongest signals where the snake is. | 0:14:49 | 0:14:53 | |
-So if you listen, you can... -BLEEPS | 0:14:53 | 0:14:56 | |
-It's a little louder that way. -It does seem stronger in that direction. | 0:15:03 | 0:15:07 | |
Perfect. I'm following you. | 0:15:07 | 0:15:09 | |
I should point out that this isn't just a magic snake-finding device. | 0:15:09 | 0:15:14 | |
All the animals we'll be looking for have been caught | 0:15:14 | 0:15:17 | |
and implanted with a radio transmitter | 0:15:17 | 0:15:19 | |
about the size of my little finger. | 0:15:19 | 0:15:22 | |
That's the signal we're trying to pick up now. | 0:15:22 | 0:15:24 | |
'So this is what we're looking for. | 0:15:25 | 0:15:28 | |
'Rattlesnakes are the classic desert predator, | 0:15:28 | 0:15:32 | |
'arguably the most sophisticated snake on the planet, | 0:15:32 | 0:15:35 | |
'with hinged fangs, a superfast strike | 0:15:35 | 0:15:39 | |
'and an amazing sense of smell. | 0:15:39 | 0:15:42 | |
'This is the animal most people try and avoid. | 0:15:43 | 0:15:47 | |
'Even with this technology, it won't be easy finding a rattler, | 0:15:51 | 0:15:55 | |
'and with the temperature soaring to over 35 degrees, | 0:15:55 | 0:15:59 | |
'the crew are really having to work hard. | 0:15:59 | 0:16:02 | |
'Matt's picked up a signal, | 0:16:04 | 0:16:06 | |
'but it isn't coming from a rattlesnake.' | 0:16:06 | 0:16:08 | |
-Sounds pretty strong. -Yeah. Here and a bit further. | 0:16:08 | 0:16:11 | |
It sounds like it's right under my feet in some way. | 0:16:11 | 0:16:14 | |
Yeah, we're very close. | 0:16:14 | 0:16:16 | |
'It's a Gila monster, an animal I've never seen up close before. | 0:16:16 | 0:16:20 | |
'If we can catch it, it'll be a real bonus | 0:16:20 | 0:16:23 | |
'and a true contender for a place on the Deadly 60. | 0:16:23 | 0:16:26 | |
'Now I've got to be extra careful here | 0:16:30 | 0:16:32 | |
'as one bite could put me in hospital.' | 0:16:32 | 0:16:34 | |
Oh, yeah, here it is, right here. | 0:16:38 | 0:16:40 | |
-Got it, got it, got it. -Well done! | 0:16:40 | 0:16:43 | |
-Oh, wow! -She's right there, right? | 0:16:45 | 0:16:48 | |
OK. | 0:16:48 | 0:16:51 | |
This is gonna be awkward. | 0:16:51 | 0:16:52 | |
-I might go up there. -Go around. | 0:16:52 | 0:16:55 | |
She will try to get away real quick if you're not careful. | 0:16:55 | 0:16:59 | |
Just don't get your hands anywhere near that mouth. | 0:16:59 | 0:17:03 | |
Got her by the tail. | 0:17:04 | 0:17:06 | |
-Bring her out gently. -OK. | 0:17:06 | 0:17:09 | |
Oh, wow! | 0:17:10 | 0:17:12 | |
Now if you can get behind the neck. | 0:17:12 | 0:17:15 | |
STEVE GRUNTS | 0:17:15 | 0:17:18 | |
-There you go. -Fabulous! | 0:17:23 | 0:17:25 | |
Absolutely fabulous! | 0:17:25 | 0:17:27 | |
Well, this wasn't what we came out here looking for, | 0:17:27 | 0:17:31 | |
but this is a creature which is definitely worthy of the Deadly 60. | 0:17:31 | 0:17:35 | |
Matt, this is the first Gila monster I've ever seen! | 0:17:35 | 0:17:39 | |
-Right on. -Great job! Absolutely wonderful! | 0:17:39 | 0:17:41 | |
-Incredible, aren't they? -Yeah. | 0:17:41 | 0:17:43 | |
That is an absolutely beautiful creature. | 0:17:43 | 0:17:48 | |
'Unlike rattlesnakes, Gila monster venom attacks the nervous system | 0:17:49 | 0:17:53 | |
'and stops their prey breathing. | 0:17:53 | 0:17:55 | |
'Luckily, it isn't usually fatal to humans, but it's famously painful. | 0:17:55 | 0:18:00 | |
'Gila monsters eat small birds, mammals and lizards. | 0:18:03 | 0:18:06 | |
'But their favourite food are bird and reptile eggs. | 0:18:06 | 0:18:09 | |
'Its fantastic sense of smell helps it locate its prey. | 0:18:09 | 0:18:13 | |
'It's said that a Gila can follow the trail of an egg | 0:18:13 | 0:18:16 | |
'rolled along the ground.' | 0:18:16 | 0:18:18 | |
They're almost preposterous-looking creatures. | 0:18:20 | 0:18:22 | |
The head looks like a dinosaur. | 0:18:22 | 0:18:25 | |
This thick tail is full of fat. | 0:18:25 | 0:18:29 | |
These are sort of storage of energy | 0:18:29 | 0:18:32 | |
which they can use, I guess, when hibernating in winter. | 0:18:32 | 0:18:35 | |
Look at these claws, almost like a bird of prey's talons, | 0:18:35 | 0:18:39 | |
perfect for digging and scrabbling around in the dirt. | 0:18:39 | 0:18:42 | |
But the head really is the business part of the Gila monster. | 0:18:42 | 0:18:46 | |
You can see it's fat and blocky, really sturdy, | 0:18:46 | 0:18:49 | |
got really positive muscles for driving heavy jaws. | 0:18:49 | 0:18:53 | |
And it's set up a bit like a pit bull terrier. | 0:18:53 | 0:18:56 | |
When they get ahold of you, they don't let go. | 0:18:56 | 0:18:58 | |
What they're actually doing with that bite | 0:18:58 | 0:19:01 | |
is allowing saliva to drip down onto their teeth | 0:19:01 | 0:19:03 | |
and actually get chewed into the wound, | 0:19:03 | 0:19:06 | |
and that venom is pretty potent. | 0:19:06 | 0:19:08 | |
It would certainly give me a nasty shock. | 0:19:08 | 0:19:10 | |
They're one of the only venomous lizards in the world. | 0:19:10 | 0:19:13 | |
That alone should give the Gila monster a place on the Deadly 60. | 0:19:13 | 0:19:17 | |
'Squat, slow and... well, a bit strange, | 0:19:19 | 0:19:22 | |
'it's not a typical Deadly 60 candidate. | 0:19:22 | 0:19:25 | |
'But being one of the only lizards in the world with a venomous bite | 0:19:25 | 0:19:28 | |
'gets the Gila monster on the Deadly 60. | 0:19:28 | 0:19:32 | |
'While we sweat it out on the search, | 0:19:37 | 0:19:39 | |
'take a look at the demo me and the crew did | 0:19:39 | 0:19:41 | |
'to show you how the rattlesnake is such an effective killer. | 0:19:41 | 0:19:46 | |
'But to do this, we need to turn the lights out.' | 0:19:46 | 0:19:50 | |
This is a thermal imaging camera. | 0:19:51 | 0:19:53 | |
It actually picks up the heat generated by objects around you. | 0:19:53 | 0:19:58 | |
So things like... | 0:19:58 | 0:20:01 | |
this cactus here. | 0:20:01 | 0:20:04 | |
Obviously cactus have an awful lot of water in them, | 0:20:04 | 0:20:07 | |
and all that water is still quite warm, | 0:20:07 | 0:20:09 | |
so the cactus stands out beautifully | 0:20:09 | 0:20:12 | |
against the black of the sky. | 0:20:12 | 0:20:14 | |
And if I turn this onto the camera crew... | 0:20:14 | 0:20:17 | |
And Johnny, the cameraman, | 0:20:17 | 0:20:20 | |
the camera's dark, | 0:20:20 | 0:20:22 | |
and his head is almost white. | 0:20:22 | 0:20:25 | |
So, got a foxy bit of kit. Let's go see what we can find. | 0:20:25 | 0:20:28 | |
'This detection of heat is exactly how a rattlesnake | 0:20:33 | 0:20:36 | |
'is able to see its prey in the dark. | 0:20:36 | 0:20:39 | |
'It has supersensitive heat sensors | 0:20:39 | 0:20:41 | |
'on its face that pick up the heat given off from its prey's body, | 0:20:41 | 0:20:45 | |
'allowing the snake to catch its supper | 0:20:45 | 0:20:48 | |
'in the pitch black of night.' | 0:20:48 | 0:20:50 | |
A good-sized rat is eyeing me up from the rocks in front of me. | 0:20:52 | 0:20:57 | |
You can see the warmth generated by his body heat. | 0:20:57 | 0:21:00 | |
His eyes, particularly, seem to be very hot. | 0:21:00 | 0:21:03 | |
I'm being watched very intently | 0:21:12 | 0:21:16 | |
from no more than about ten feet away, | 0:21:16 | 0:21:18 | |
by a very bright pair of yellow eyes. | 0:21:18 | 0:21:22 | |
This is an Elf Owl. | 0:21:23 | 0:21:26 | |
He's probably... | 0:21:26 | 0:21:28 | |
no more than about that high, I'm guessing. | 0:21:28 | 0:21:32 | |
He is beautiful. | 0:21:32 | 0:21:35 | |
'This is exactly what a rattlesnake would see | 0:21:35 | 0:21:38 | |
'if it was looking at this owl. | 0:21:38 | 0:21:39 | |
'Now let's turn the lights back on and see if we can find one.' | 0:21:43 | 0:21:49 | |
Ow! | 0:21:54 | 0:21:56 | |
Some of these cactus could be well over 100 years old. | 0:22:01 | 0:22:05 | |
Even older than Nick, our sound man. | 0:22:05 | 0:22:08 | |
STEVE LAUGHS | 0:22:09 | 0:22:12 | |
There's a lot of reasons why reptiles do so well in dry desert environments like this. | 0:22:15 | 0:22:20 | |
Firstly, being so-called cold-blooded, | 0:22:20 | 0:22:22 | |
they get their energy from the sun, and there's plenty of that here. | 0:22:22 | 0:22:26 | |
Also, they have remarkable watertight skin, | 0:22:26 | 0:22:29 | |
so they don't sweat or use any water from the outside environment. | 0:22:29 | 0:22:33 | |
They have the ability, in times when there's not much food around, | 0:22:33 | 0:22:36 | |
to just lie around and do nothing, | 0:22:36 | 0:22:39 | |
and, in extreme cases, even hibernate. | 0:22:39 | 0:22:41 | |
Oh! Look what you just stepped over. | 0:22:43 | 0:22:46 | |
-Oh, my goodness. -Johnny, look at this. | 0:22:46 | 0:22:48 | |
Well! We're out looking for reptiles... | 0:22:48 | 0:22:53 | |
but this one wasn't on our minds. | 0:22:53 | 0:22:55 | |
It's a deadly tortoise. | 0:22:55 | 0:22:58 | |
-Matt, what species is this? -That'd be the Desert Tortoise. | 0:22:58 | 0:23:02 | |
-I guess it's called that because it lives in the desert. -Yeah. | 0:23:02 | 0:23:06 | |
THEY LAUGH | 0:23:06 | 0:23:08 | |
-Those things do a good impression of a rock. -They certainly do. | 0:23:08 | 0:23:13 | |
The Desert Tortoise has a way of dealing with heat and predators. | 0:23:13 | 0:23:17 | |
It doesn't need to hide in the rocks. | 0:23:17 | 0:23:19 | |
It takes its own home and protection along with it. | 0:23:19 | 0:23:23 | |
Great stuff. | 0:23:23 | 0:23:25 | |
That one is a snake. | 0:23:36 | 0:23:38 | |
'Matt's locked on to a signal from a rattlesnake. | 0:23:38 | 0:23:41 | |
'We're getting close and we need to be really careful where we tread.' | 0:23:41 | 0:23:46 | |
-Where? -You see him? | 0:23:50 | 0:23:52 | |
OK, he's right there? Good. | 0:23:52 | 0:23:55 | |
Perfect. | 0:24:00 | 0:24:01 | |
If you can get him on the first shot, that's good. | 0:24:03 | 0:24:06 | |
One fell swoop. | 0:24:06 | 0:24:09 | |
Come around the other side now. | 0:24:11 | 0:24:13 | |
RATTLING | 0:24:13 | 0:24:16 | |
Listen to that! | 0:24:16 | 0:24:18 | |
That is THE sound of the Sonoran Desert. | 0:24:18 | 0:24:24 | |
RATTLING | 0:24:25 | 0:24:27 | |
Let's get him out in the open where we can look at him. | 0:24:32 | 0:24:35 | |
RATTLING | 0:24:37 | 0:24:39 | |
Listen to that rattle! | 0:24:40 | 0:24:42 | |
LOUD RATTLING | 0:24:45 | 0:24:47 | |
That wonderful sound is really the signature sound of the desert. | 0:24:47 | 0:24:52 | |
You hear it in all the Western movies. | 0:24:52 | 0:24:54 | |
Interlocking segments of keratin, | 0:24:56 | 0:24:59 | |
the same substance that's in our fingernails, | 0:24:59 | 0:25:02 | |
rattle together and create that incredible buzzing sound. | 0:25:02 | 0:25:06 | |
'Matt's marked the wild snakes he's studying with some paint | 0:25:07 | 0:25:11 | |
so he can identify them.' | 0:25:11 | 0:25:13 | |
This is a tiger rattlesnake. | 0:25:14 | 0:25:18 | |
The dark and light bands running across the body | 0:25:18 | 0:25:21 | |
are for camouflage and are what give it its name. | 0:25:21 | 0:25:24 | |
These tongs look like they're squashing the snake, but it's a resilient creature. | 0:25:25 | 0:25:30 | |
They're not doing it any harm at all. | 0:25:30 | 0:25:33 | |
It's not a particularly big snake, but it does have very potent venom. | 0:25:33 | 0:25:38 | |
Certainly enough to mean I have to be very wary of it. | 0:25:38 | 0:25:41 | |
What a beauty! | 0:25:41 | 0:25:43 | |
Actually, what this is is an incredible predator. | 0:25:43 | 0:25:47 | |
The reason for that is a supersense. | 0:25:47 | 0:25:49 | |
Looking at the front of the head, | 0:25:49 | 0:25:51 | |
the snake almost appears to have two sets of nostrils. | 0:25:51 | 0:25:55 | |
The lower ones are what's called a loreal pit, | 0:25:55 | 0:25:59 | |
which picks up the warmth generated by the moving muscles of its prey. | 0:25:59 | 0:26:03 | |
It can literally see animals moving in the dark. | 0:26:03 | 0:26:07 | |
'Exactly as we saw earlier with our thermal camera.' | 0:26:08 | 0:26:12 | |
So all it has to do is to sit and wait | 0:26:14 | 0:26:17 | |
for a small mouse or other warm-blooded mammal to walk too close by, | 0:26:17 | 0:26:21 | |
and then it'll strike with its potent venom. | 0:26:21 | 0:26:24 | |
First of all, it instantly starts to slow the prey down. | 0:26:24 | 0:26:28 | |
But the prey also starts to bleed internally | 0:26:32 | 0:26:35 | |
and to urinate as it runs away, | 0:26:35 | 0:26:37 | |
leaving a scent trail which the rattlesnake can follow. | 0:26:37 | 0:26:41 | |
'So, dangerous to us they may be, | 0:26:42 | 0:26:45 | |
'but the rattlesnake is going on the Deadly 60 | 0:26:45 | 0:26:47 | |
'because of its ability to track, ambush and immobilise its prey. | 0:26:47 | 0:26:53 | |
'Venom, speed, supersenses, camouflage, | 0:26:57 | 0:27:00 | |
'and... did I mention venom? | 0:27:00 | 0:27:03 | |
'Well, there you go. The rattlesnake. | 0:27:03 | 0:27:06 | |
'Coming up next time on the Deadly 60: | 0:27:10 | 0:27:12 | |
Look at that! | 0:27:23 | 0:27:25 | |
