00:00:12 On the edge of a lush forest
00:00:16 a hunter is on the prowl.
00:00:41 Terney,
00:00:46 This is no longer a place of exile,
00:00:48 but today's Siberians
00:00:52 trapping, fishing, and logging.
00:00:55 They live on
00:00:58 surrounded by a vast
00:01:04 And still, out there somewhere,
00:01:15 A creature of fearful power
00:01:23 It is the biggest cat on earth...
00:01:35 Today wildlife biologists
00:01:38 and perhaps to save it.
00:01:42 About three hundred Siberian tigers
00:01:47 And they are perilously
00:01:52 These Russian and American scientists
00:01:54 must get close to one of the most
00:02:23 But while some seek
00:02:30 one Russian scientist
00:02:34 mating and hunting.
00:02:38 Made for Siberia,
00:02:39 this splendid cat can sprint across
00:02:46 Magnificent. Mysterious.
00:02:50 Highly dangerous and
00:02:54 This is the great Siberian -
00:03:45 A vast stretch of forest
00:03:47 with a fourth of the world's
00:03:51 Until recently the Siberian Tiger
00:03:57 Under the strict dictates
00:04:00 the tiger was protected.
00:04:02 But today, enforcement is lax.
00:04:08 Rampant poaching
00:04:11 the population of tigers in the wild.
00:04:35 In the Asian medicine market,
00:04:37 everything from the eyes
00:04:40 for its legendary curative powers.
00:04:43 The magnificent coat alone
00:04:49 But poachers aren't the only threat.
00:04:56 The tiger's habitat,
00:04:57 part of the largest natural forest
00:05:00 is rapidly disappearing.
00:05:03 It's being cut at a rate of
00:05:12 When authorities confiscate a pelt
00:05:15 it must be destroyed so it will
00:05:20 Recalling a poet's famous words...
00:05:23 "Tiger, Tiger burning bright
00:05:36 The coast of Eastern Siberia.
00:05:40 The Siberian tiger once ranged
00:05:46 Once they numbered in the thousands.
00:05:50 Now, only some three hundred survive
00:05:53 in a narrow band of mountains
00:06:01 The Siberia of legend
00:06:05 In fact, parts of the forest
00:06:15 Here,
00:06:17 are seeking to study
00:06:20 in a last-ditch effort to save them.
00:06:23 Dr. Maurice Hornocker,
00:06:27 has brought desperately needed
00:06:33 "Yeah, that's good, too."
00:06:35 In the past, Russian scientists
00:06:39 when their tracks
00:06:43 Now, with radio tracking devices,
00:06:45 the elusive cats can be studied
00:07:00 "My first work with cats,
00:07:01 with the mountain lions
00:07:05 everyone said it couldn't be done -
00:07:09 We've used the tiger population
00:07:12 but we've studied the entire
00:07:15 Because of the immense area
00:07:19 defines entire watersheds,
00:07:23 that the prey must also utilize.
00:07:26 So you can literally define
00:07:29 by studying a big cat."
00:07:33 The scientists pick up
00:07:36 somewhere in the thick forest below.
00:07:44 In fact, it's a number of tigers.
00:07:47 And incredibly,
00:08:05 Siberian tigers are so rare and elusive
00:08:08 that even a fleeting glimpse
00:08:10 is a landmark event
00:08:13 "When we saw that female and
00:08:16 on its lakeshore - wide open view - first time
00:08:19 that a female Siberian tiger and
00:08:23 and photographed from the air -
00:08:24 it was one of the most thrilling
00:08:36 Hornocker's team has tracked
00:08:40 trying to determine such
00:08:41 as their range and distribution.
00:08:49 At the field lab of the Hornocker
00:08:52 Maurice is briefed by Dale Miquelle,
00:08:55 who's been coordinating the field
00:08:59 "...we've got five females
00:09:00 that we've got good information
00:09:02 Um, we've got Olga, the four,
00:09:04 first female we captured
00:09:07 that only includes a little piece
00:09:10 um, and then we've got..."
00:09:11 Together with their Russian colleagues,
00:09:13 they need to quickly establish
00:09:16 "The, one of the things that's interesting about all of this
00:09:18 is that all these animals travel
00:09:21 so, even though the reserve is vast,
00:09:23 it's not large enough
00:09:26 in their entire home range."
00:09:28 Time is running out.
00:09:31 Even now,
00:09:34 where only some twenty tigers
00:09:46 The researchers receive word
00:09:47 that a tiger has been caught
00:09:51 a chance to add a new animal
00:09:56 Bart Schleyer and Dr. Hornocker
00:10:04 "I don't see her."
00:10:07 There is no way of knowing
00:10:11 He could suddenly pull free
00:10:13 and then they would have only
00:10:59 A tranquilizer dart should quiet the tiger down.
00:11:02 Still, the dosage required
00:11:06 Too much endangers the tigers.
00:11:47 It's a three-year-old male.
00:11:50 When fully grown, at about age six,
00:11:52 he'll weigh six hundred pounds
00:11:56 But even now he's an armful.
00:11:58 "This is about all we can do, guys.
00:12:02 They carry the tiger
00:12:07 "Gonna lubricate his eyes."
00:12:10 His eyes must be
00:12:12 since the blink response is sedated.
00:12:17 "Let's get this snare off."
00:12:21 These massive jaws can crack
00:12:25 with a single bite.
00:12:26 "Young male tiger."
00:12:30 Its feet are like thickly padded
00:12:36 "Boy, he's a beautiful animal."
00:12:38 "Yeah, gorgeous."
00:12:42 The radio collar allows them
00:12:44 and help answer some
00:12:47 How much territory
00:12:50 How many elk and deer and boar?
00:12:53 How do they react
00:13:01 Suddenly, the tiger is having
00:13:08 They desperately try to revive him.
00:13:10 "I'm gonna give him something."
00:13:12 "And someone should keep..."
00:13:15 "His eyes are moving."
00:13:16 "Yeah, but his breaths are real low."
00:13:18 "Give it to him."
00:13:42 "That collar's cut, Maurice?
00:13:46 'Cause we might have a cat
00:13:50 The tiger must be given a stimulant.
00:13:59 Slowly he resumes
00:14:05 "Yeah, he's breathing.
00:14:08 "Yeah, he's breathing.
00:14:12 Whew, man, that was...
00:14:14 "Yeah."
00:14:15 The biologists must now
00:14:18 before the great beast fully awakens.
00:14:56 They're reluctant
00:14:58 before he's safely on his feet -
00:15:19 Now at a safe distance,
00:15:21 the team receives a signal
00:15:24 The tiger is up and about...
00:15:37 In another part of the reserve,
00:15:38 the team is concerned about the
00:15:42 She was the very first
00:15:46 Olga, it appears, has remained in
00:15:51 a sign that she may be dead -
00:15:53 or that she has found a den
00:16:11 Dr. Evgeny Smirnov,
00:16:14 determines that Olga is, in fact,
00:16:27 The researchers decide
00:16:29 they'll attempt to enter the den
00:16:32 They'll need to wait until night
00:16:34 when the tigress should be
00:16:36 Hopefully, far from home.
00:16:46 "I asked if he thought, uh, it would be dangerous
00:16:49 or we'd, we'd be in trouble if we went there and he said,
00:16:53 'Of course, it'd be dangerous,
00:16:57 to approach when she's not there,
00:16:58 because it's simply too dangerous
00:17:01 with the, the mother present."'
00:17:07 He said, "Thank God",
00:17:08 we have the telemetry equipment to
00:17:12 and so we know, exactly,
00:17:16 Without that it, it'd simply be a,
00:17:29 The fading radio signal indicates
00:17:35 But if she returns
00:17:41 They test flares
00:17:46 Protecting a den is one
00:17:49 when a Siberian will turn man-killer.
00:18:09 Night is the time when tigers
00:18:14 Their night vision is far superior
00:18:23 The signal from Olga - once faint -
00:18:26 is getting louder.
00:18:28 The team must quickly
00:18:51 "Yeah this is it. This is it, Bart."
00:18:54 "Yeah, yeah, we've got the spot.
00:18:56 "Do you see a cat?"
00:18:58 "Yeah."
00:19:00 Gloves soaked with tiger urine
00:19:02 so the mother will not detect
00:19:38 "Get away."
00:19:54 It's a healthy male.
00:19:56 Two months old, the cub already
00:20:02 "Dale, I'm still getting a signal
00:20:04 and it's really not that weak
00:20:07 we're probably going to
00:20:16 Unlike other cats, tiger kittens
00:20:26 An ear tag is inserted
00:20:30 They christen the cub Sasha.
00:20:34 "I'm getting a signal,
00:20:36 she's back,
00:20:48 Their daring has set a new precedent.
00:20:51 For the first time ever,
00:20:52 scientists have examined and
00:21:04 In towns and villages throughout
00:21:08 people have learned to live
00:21:12 But attacks have happened
00:21:17 In the village of Guyvaron,
00:21:18 however, one man is happy to
00:21:23 Maurice Hornocker and Howard Quigley
00:21:25 are working with a Russian biologist
00:21:27 who has two orphaned cubs
00:21:32 "That's a big male tiger."
00:21:35 Victor Yudin has raised the cubs
00:21:45 Victor is the author of a definitive
00:21:50 But he soon learned that Kuchur, the tiger...
00:21:53 ...and Niurka, the tigress,
00:22:09 "To study tigers in captivity
00:22:12 because many of their biological
00:22:19 Comparing the results
00:22:21 that were done in captivity
00:22:24 helps us to develop the methods
00:22:28 as a species in reserves
00:22:33 The young tigers have
00:22:35 and so, with the support of the
00:22:39 an enclosure is built
00:22:44 Though a far cry from the hundreds
00:22:47 a tiger in the wild would roam,
00:22:49 these six acres will provide
00:22:52 with the opportunity to run
00:22:55 - and hopefully -
00:23:01 But there are neighbors
00:23:04 Victor knows the importance
00:23:08 Especially now,
00:23:09 when the tigers will soon be turned
00:23:14 So he brings local school children
00:23:21 "Villagers often come to see
00:23:25 They often ask me:
00:23:29 since it's so different
00:23:45 "I explain to them
00:23:47 to what we can and cannot learn
00:23:49 from observing tigers the way we do
00:23:52 by simply following tracks
00:24:04 Afterwards, when people realize
00:24:08 that it's serious work
00:24:11 as if I were a superman, I guess."
00:24:25 The day has come
00:24:28 the tigers will step into the natural
00:24:35 No one knows how they will react
00:24:42 For Victor, it's an especially
00:24:46 for he hopes the enclosure
00:24:49 for the rest of their lives.
00:25:11 The male, Kuchur, steps boldly out.
00:25:17 For the first time...
00:25:21 the smell of grass and leaf,
00:25:29 Niurka, the female,
00:25:32 and even tries to close the gate.
00:25:35 But soon,
00:25:58 To Yudin's surprise,
00:26:00 Kuchur begins to feel a little frisky
00:26:04 But Niurka will have no part of it.
00:26:06 For her, the time has not yet come.
00:26:10 Exhilarated by their freedom,
00:26:12 they soon vanish into
00:26:22 To feed his feline charges,
00:26:27 Victor feels he knows the mood
00:26:31 he can risk entering the enclosure.
00:26:49 In the wild, most attacks
00:26:52 when they invade a tiger's territory
00:26:57 Unlike Bengal tigers, Siberians
00:27:13 As the tigers settle into
00:27:16 Dr. Yudin begins his observations
00:27:21 He hopes to learn
00:27:24 and which would need to be taught
00:27:27 before they could be released
00:27:31 Tigers live in a world of feast
00:27:35 Still, Kuchur must wait his turn.
00:27:38 Dr. Yudin notices it's the female
00:27:53 With the coming of fall,
00:27:54 the first brisk winds blow in
00:28:03 As if designed
00:28:05 the tigers blend with the landscape.
00:28:08 In the wild,
00:28:11 as winter approaches,
00:28:29 Dr. Yudin confronts one more problem
00:28:31 that makes the study
00:28:36 The tiger is largely
00:28:50 With their extraordinary
00:28:52 Kuchur and Niurka come fully alive
00:29:00 Recently, they've begun to roam
00:29:04 Victor wonders if night has
00:29:11 When he releases a small rabbit
00:29:13 he quickly learns the answer.
00:29:52 After several weeks,
00:29:53 the tigers have established
00:29:57 How would they react to another
00:30:02 Yudin and Hornocker set up
00:30:04 involving a full-sized model tiger.
00:30:07 "Okay. A little more."
00:30:10 "I'm interested to see
00:30:13 Is that as big as Kuchur?"
00:30:15 "Yes..."
00:30:18 "These will match right up
00:30:21 You got that back there?"
00:30:25 "Yeah, it's good."
00:30:28 "Yeah, that's a good fit.
00:30:30 Okay, let's see what it looks like
00:30:42 Victor's dogs are convinced.
00:30:45 They immediately recognize
00:31:03 Tigers in the wild are solitary
00:31:08 Is this behavior innate or learned?
00:31:11 And, if innate,
00:31:15 The reaction to an intruder
00:31:19 may help provide an answer.
00:31:25 The scale model is covered
00:31:28 the scent that establishes territory.
00:31:39 Recordings of tiger calls will be
00:31:45 The stage is set.
00:32:08 Kuchur, the male, is curious.
00:32:11 He spends hours observing
00:32:21 But by light of day,
00:32:29 It's only overnight
00:32:31 the tigers' real attitude
00:32:35 Every shred of color has been ripped
00:32:40 Only when the model
00:32:43 did Kuchur leave it alone.
00:32:46 The defense of his territory
00:33:05 It was the long Siberian winter
00:33:11 demanding robust size,
00:33:16 But it is also winter
00:33:19 when they are most easily seen...
00:33:24 "We've had to develop and
00:33:29 No one had ever worked
00:33:31 So, we utilized foot-snaring
00:33:35 and it's worked very successfully.
00:33:37 But, some of them are becoming
00:33:39 some of them have become very,
00:33:43 So in order to maintain the
00:33:47 in order to keep track
00:33:50 we've had to utilize helicopters."
00:33:55 The hunt begins to re-collar
00:33:58 The information the collars provide
00:34:01 to understanding the boundaries
00:34:08 Their territories are extensive.
00:34:11 Females may range up to
00:34:14 males perhaps five hundred.
00:34:18 Losing contact with a study animal
00:34:22 Each one is precious
00:34:25 "The collars we put on animals last
00:34:30 and then the batteries,
00:34:32 so they simply need to be replaced.
00:34:34 Once we've invested two years in
00:34:39 that animal becomes very valuable
00:34:42 And the longer we can maintain
00:34:45 the more we learn about
00:34:48 how often it has young,
00:34:51 its whole life history."
00:34:58 The pilot spots something below.
00:35:02 It's a wild boar
00:35:07 And in pursuit a tiger.
00:35:20 Tigers miss most of their prey.
00:35:23 This time the helicopter provides
00:35:28 The tiger is not amused.
00:35:43 Eventually they pick up the strong
00:35:56 It is Olga, mother of the cub
00:36:01 The helicopter quickly searches the
00:36:11 And Sasha is there - no longer
00:36:20 The young are raised
00:36:23 Sasha will stay with her
00:36:26 until it's time to establish
00:36:34 The search continues for Kouza
00:36:36 a young male who has outgrown
00:36:40 Kouza is just beginning
00:36:43 and it's difficult to know
00:36:48 Tranquilizing a Siberian tiger
00:36:53 The size of the tiger, its mood -
00:36:56 and the placement of the dart can
00:37:00 Always, out of concern for the tiger,
00:37:02 the team tries to inject
00:37:20 After long hours
00:37:24 the tiger is spotted.
00:37:26 In pursuit, the helicopter must fly
00:37:30 a dangerous maneuver.
00:37:37 It's a far cry from hunting
00:37:41 "There's usually just a real
00:37:44 and sometimes there's a limb
00:37:47 and there's been a number of times
00:37:49 when I probably could have gotten
00:37:53 but I'm too worried about
00:37:56 and having the, the dart deflect into
00:38:01 which would injure it,
00:38:04 So, I'm real, real stressed by trying
00:38:22 As the tiger moves deeper
00:38:24 the helicopter follows so closely
00:38:29 "The pilots we're using,
00:38:33 because you are operating
00:38:36 and you just hope that the pilots
00:38:40 around behind them particularly
00:38:44 and particularly the other day when
00:38:48 there was a conifer tree
00:38:49 that was actually almost butted
00:38:57 The first shot is a clean hit.
00:39:02 They hover patiently waiting for
00:39:07 But they can't wait too long -
00:39:34 Bart fires another dart
00:39:37 Most big cats need two doses.
00:39:40 And the second one appears to
00:39:45 Bart and Rybin Nikolai
00:39:49 This too is a dangerous maneuver.
00:39:51 But they can't leave the tiger
00:40:08 The pilot is very concerned now.
00:40:10 They must refuel.
00:40:12 He radios Bart to abort the mission.
00:40:15 But Bart insists -
00:40:18 they must remain below
00:40:22 The helicopter races back to refuel.
00:40:30 As they slowly approach the tiger,
00:40:36 The tiger is up and moving.
00:40:38 The dosage was insufficient.
00:40:46 Still, they must get a closer look
00:41:00 They proceed with caution
00:41:01 knowing they are intruding
00:41:03 in a fierce young tiger's newly
00:41:09 Kouza appears groggy
00:41:13 But he's much too dangerous
00:41:18 Now they can only await
00:41:21 And hope the young tiger has seen
00:41:38 For now, the tiger has eluded them,
00:41:40 but at least they know
00:41:43 Eventually, he'll be located
00:41:49 At last, they are brought aboard -
00:41:51 to the relative safety of a
00:42:02 Not long after, they spot a tigress
00:42:06 She is very aggressive -
00:42:08 and even climbs a tree
00:42:14 She only provides a better target
00:42:26 Unlike the larger male, a single dose
00:42:34 "Let's take blood
00:42:40 The old collar is measured
00:42:42 which is given an extra notch
00:42:57 They carefully monitor
00:43:02 "Where's that? 10?"
00:43:03 "That's right..."
00:43:07 Mission accomplished.
00:43:09 The new collar will provide crucial
00:43:22 Not far from the cold,
00:43:25 the success of the venture
00:43:29 It's also Bart Schleyer's birthday.
00:43:33 For American and Russian alike
00:43:34 it's a camaraderie born of years of
00:43:59 At Victor Yudin's compound winter
00:44:07 The Siberian winter seems to
00:44:12 This is truly the season of
00:44:36 As Victor Yudin observes,
00:44:38 Kuchur, the male, continues to
00:44:42 spraying the trees with his scent.
00:44:45 In what is called a 'flehmen' the
00:44:51 Then it's Kuchur's turn to
00:44:57 And she is.
00:44:59 Niurka, the female,
00:45:02 And so the mating period begins.
00:45:12 "If we succeed in getting young cubs
00:45:15 because then we can develop
00:45:18 for returning the young tigers
00:45:24 We'll try to bring them up
00:45:26 so they will more easily adapt to
00:45:31 here in the reserve."
00:45:38 As for a successful mating,
00:45:40 all Dr. Yudin can do
00:45:58 Victor's wife, Lena, has a special
00:46:02 She's nurtured them
00:46:05 When they must be brought in
00:46:06 because of the dangers of poaching,
00:46:08 only their Babushka
00:46:52 Over the next few days,
00:46:56 Sometimes dozens of times a day.
00:46:59 At last, the breeding ends,
00:47:05 She should give birth
00:47:19 Springtime in Siberia.
00:47:22 Dr. Hornocker receives word from
00:47:25 that Niurka has given birth.
00:47:29 But something's wrong.
00:47:39 Victor's observed that the mother
00:47:45 This is not uncommon when
00:47:54 "Does Victor think
00:48:01 "Probably not."
00:48:03 "Then we better go in and look, Victor."
00:48:07 They isolate the mother, Niurka,
00:48:27 One of the cubs is up and about
00:48:32 The other cub is barely moving and
00:48:42 "How is he?"
00:48:46 "Yeah, oh yeah, the poor little guy."
00:49:04 Suddenly, the cub stops breathing.
00:49:09 Victor rushes it inside
00:49:28 It appears the mother has neither
00:49:33 and this one is near death.
00:49:39 With infinite patience,
00:49:43 Hoping - against all odds -
00:50:16 The mortality rate of Siberian tiger
00:50:23 With so few born in the wild,
00:50:25 the survival of captive cub
00:50:39 One cub is lost,
00:50:41 but her brother - under Victor's
00:50:46 He's named the cub Globus -
00:50:48 for a world that cares about him,
00:50:51 even if his own mother
00:51:15 Eventually Globus will be brought
00:51:18 as part of a captive
00:51:26 When he is, he'll be following
00:51:28 orphaned in Siberia and
00:51:31 to the snows of Omaha, Nebraska.
00:51:35 They're now part of the world's most
00:51:38 for large predators.
00:51:40 The tigers are bred here
00:51:41 with the goal of returning the cubs
00:51:47 But what kind of environment
00:51:55 Back in Russia,
00:51:56 Dr. Hornocker strives to educate
00:52:02 "If we're to save these big carnivores
00:52:06 we must convince
00:52:09 that it's worthwhile
00:52:11 It's always so rewarding to me
00:52:13 and gratifying to see how
00:52:17 They really love these big animals.
00:52:19 They want to save them.
00:52:21 And if we can convince them
00:52:22 that it's in their best interest then
00:52:29 Soon, much of this magnificent
00:52:32 the Siberian tiger's last domain -
00:52:35 may be cut down for a world
00:52:41 But the years of difficult and
00:52:44 to a plan to save the forest...
00:52:50 Selecting the tiger as the
00:52:54 means that the forest surrounding
00:52:59 But in a land of political
00:53:02 there are no guarantees.
00:53:06 Poised on the edge of extinction,
00:53:09 the tiger of the snow evokes
00:53:14 Hope is the last to die.
