0:00:19 > 0:00:22This tiger is the chosen one.
0:00:24 > 0:00:27She will be taken from her home
0:00:27 > 0:00:30and released into unknown territory.
0:00:33 > 0:00:36She will face a struggle to survive
0:00:36 > 0:00:39in a world full of uncertainty.
0:00:45 > 0:00:48SHE GROWLS
0:00:53 > 0:00:58Her challenge is to begin a new dynasty of tigers,
0:00:58 > 0:01:01and help to save her species.
0:01:01 > 0:01:04SQUEALS AND BARKS ERUPT SUDDENLY
0:01:19 > 0:01:22Ranthambore National Park
0:01:22 > 0:01:25is one of India's most magical wild places.
0:01:29 > 0:01:33And home to a healthy population of Royal Bengal tigers.
0:01:38 > 0:01:42Including one very special young female.
0:01:45 > 0:01:48Relaxed and confident,
0:01:48 > 0:01:53four-year-old Baghani is completely at home in this forest.
0:01:58 > 0:02:00Baghani and I are old friends.
0:02:00 > 0:02:03'I've been filming her since she was a cub.
0:02:06 > 0:02:10'My name is Nalla and tigers are my passion.'
0:02:19 > 0:02:22SHE SPRAYS THE ROCK
0:02:22 > 0:02:25'What I know, and Baghani doesn't,
0:02:25 > 0:02:28'is that her life is about to change forever.'
0:02:30 > 0:02:34DISTANT HELICOPTER GETS LOUDER
0:02:44 > 0:02:50'Baghani has been chosen for a very special mission.'
0:02:52 > 0:02:54She'll be drugged, captured and transported
0:02:54 > 0:02:58far from her Ranthambore home to Sariska National Park.
0:03:05 > 0:03:09Sariska was one of India's top tiger reserves,
0:03:09 > 0:03:13until all its tigers were wiped out by poachers.
0:03:14 > 0:03:18'But with the poachers now behind bars,
0:03:18 > 0:03:23'Baghani will be key to an ambitious plan to reintroduce tigers
0:03:23 > 0:03:24'to Sariska.
0:03:27 > 0:03:29'This has never been attempted before.
0:03:29 > 0:03:31'If successful,
0:03:31 > 0:03:34'it will be a breakthrough for tiger conservation.
0:03:51 > 0:03:55'The great hope is that Baghani will begin a new dynasty of tigers
0:03:55 > 0:03:58'in Sariska.'
0:03:58 > 0:04:00But she can't do that alone.
0:04:01 > 0:04:05Joining her from Ranthambore will be a potential suitor.
0:04:05 > 0:04:09A hot-blooded male called Rajore.
0:04:14 > 0:04:17'I'll be part of a team following them
0:04:17 > 0:04:20'as they struggle to make a new life in their new home.
0:04:24 > 0:04:27'And when I can't film, remote cameras will help me
0:04:27 > 0:04:29'keep track of what's happening.'
0:04:36 > 0:04:38TIGER ROARS
0:04:38 > 0:04:43'Rajore is the first tiger to set foot in Sariska for four years.'
0:04:43 > 0:04:46ROARING CONTINUES
0:04:46 > 0:04:49Baghani follows after.
0:04:54 > 0:04:58All I can do now is watch and hope.
0:05:04 > 0:05:06The next day, I'm up early.
0:05:06 > 0:05:10Finding Baghani in Sariska's dense forest could take a while.
0:05:16 > 0:05:20GENTLE CRIES OF ANIMALS
0:05:24 > 0:05:28But before too long, I catch a glimpse of my young friend.
0:05:30 > 0:05:32TIGER PANTS
0:05:39 > 0:05:42You get to know a tiger's moods
0:05:42 > 0:05:45when you watch them for as long as I have.
0:05:48 > 0:05:50She seems dazed....
0:05:51 > 0:05:53..timid.
0:05:54 > 0:05:56A bit lost.
0:05:58 > 0:06:02The sights, sounds and smells are all unfamiliar.
0:06:03 > 0:06:05She must be so confused.
0:06:12 > 0:06:15At least some of the locals are friendly.
0:06:27 > 0:06:31Getting used to living here is going to take time.
0:06:35 > 0:06:40It doesn't take much to spook her in this strange new world.
0:06:40 > 0:06:43CRIES FROM THE FOREST
0:06:46 > 0:06:49SHE GROWLS
0:06:50 > 0:06:55MONKEYS CHATTER
0:07:04 > 0:07:07The tigers' arrival has not gone unnoticed.
0:07:08 > 0:07:13Leopards are normally no match for a tiger.
0:07:13 > 0:07:16But their numbers have increased since poachers killed
0:07:16 > 0:07:18the last of Sariska's tigers.
0:07:19 > 0:07:23They will not welcome the return of the competition.
0:07:25 > 0:07:28And they could be a real threat to Baghani.
0:07:28 > 0:07:31BUSHES RUSTLE
0:07:35 > 0:07:39For now, though, something else has caught her eye.
0:07:46 > 0:07:50CHIRRUPS AND SQUEAKS FROM THE TREES
0:07:52 > 0:07:54She's hungry.
0:07:54 > 0:07:57And it's good to see her instincts take over,
0:07:57 > 0:07:59despite her new surroundings.
0:08:43 > 0:08:45But I don't think she's hunting.
0:08:47 > 0:08:50I think she's exploring, learning.
0:08:53 > 0:08:55She's been spotted by a langur.
0:08:58 > 0:09:01She must be tempted to make an attack.
0:09:03 > 0:09:06VARIOUS ANIMALS CHATTER
0:09:11 > 0:09:16But however hungry she is, Baghani doesn't know this place yet.
0:09:20 > 0:09:23ANIMALS CONTINUE CHATTERING
0:09:23 > 0:09:26She doesn't know the best spot for an ambush
0:09:26 > 0:09:29or which way her prey is likely to run.
0:09:33 > 0:09:36DEER BARKS
0:09:36 > 0:09:39The Sambar deer hasn't smelt a tiger for four years.
0:09:45 > 0:09:48But finally, it sounds the alarm.
0:09:50 > 0:09:53DEER BARKS
0:10:09 > 0:10:12It might seem like a failure.
0:10:14 > 0:10:16But I think Baghani's biding her time...
0:10:17 > 0:10:21..waiting for the Sambar deer to return.
0:10:23 > 0:10:26FLIES BUZZ

0:10:31 > 0:10:34HONKING
0:10:39 > 0:10:43It looks like she won't be allowed to rest in peace.
0:10:52 > 0:10:57I'm told there are more peacocks in Sariska than anywhere else in India.
0:11:00 > 0:11:04If this peacock spots Baghani, it'll sound the alarm,
0:11:04 > 0:11:07and the whole forest will be on alert again.
0:11:11 > 0:11:12Baghani could grab the peacock,
0:11:12 > 0:11:16but it's not worth it for such a small meal.
0:11:23 > 0:11:25Baghani's a clever tiger.
0:11:25 > 0:11:27She plays dead.
0:11:31 > 0:11:33And it works.
0:11:37 > 0:11:39The peacock never knew she was there.
0:11:45 > 0:11:48Soon Baghani hears something.
0:11:48 > 0:11:52CALLS FROM THE TREES
0:11:56 > 0:11:57ANOTHER CALL
0:11:58 > 0:12:01This time it really looks like she's hunting.

0:12:31 > 0:12:32Has she blown it?
0:12:38 > 0:12:42I don't think so. She's beginning to make her way downwind.
0:12:55 > 0:12:58I think she's going to try an ambush.

0:14:27 > 0:14:29DEER BARKS
0:14:41 > 0:14:43It's not a good start.
0:14:43 > 0:14:47The longer it takes to eat, the weaker she'll become,
0:14:47 > 0:14:50and the weaker she becomes, the harder it is to hunt.
0:14:55 > 0:14:57These first few days are critical.
0:15:08 > 0:15:12Food is not the only challenge the tigers will face.
0:15:12 > 0:15:15GENERAL HUBBUB
0:15:15 > 0:15:18Sariska is not a pristine wilderness.
0:15:18 > 0:15:20People live here.
0:15:22 > 0:15:24There's a bustling temple.
0:15:24 > 0:15:27And a road runs right through the park.
0:15:36 > 0:15:40This morning Rajore, the male tiger, is checking it out.
0:15:40 > 0:15:43He's exploring his new home.
0:15:47 > 0:15:50And announcing his presence by scent-marking.
0:15:51 > 0:15:53It's tiger posturing.
0:15:56 > 0:16:00It says, "I'm big, I'm the best and I'm here,"
0:16:00 > 0:16:03much to the alarm of the neighbours.
0:16:03 > 0:16:05ANIMALS BARKING AND HONKING
0:16:05 > 0:16:08Unfortunately, he's claiming an area near the local villages.
0:16:11 > 0:16:1515,000 people live within this tiger reserve.
0:16:18 > 0:16:22They have been offered money to leave but most have refused.
0:16:22 > 0:16:24They feel this is THEIR home.
0:16:27 > 0:16:32The poaching has stopped, but these villagers are still a threat.
0:16:32 > 0:16:35They will kill tigers who threaten them or their cattle.
0:16:36 > 0:16:41I hope Rajore and Baghani are smart enough to keep their distance.
0:16:47 > 0:16:51It's forbidden to film in the reserve at night.
0:16:52 > 0:16:56But the remote cameras keep watch for me.
0:17:04 > 0:17:07And tonight Rajore is on the prowl.
0:17:11 > 0:17:14He's being shadowed by a leopard.
0:17:16 > 0:17:19And another with a dog for dinner.
0:17:22 > 0:17:26I've never seen leopards and tigers this close before.
0:17:26 > 0:17:28This could mean trouble.
0:17:33 > 0:17:35Even with the radio collars,
0:17:35 > 0:17:39I can't follow Rajore or Baghani all the time.
0:17:41 > 0:17:45'They often disappear into areas I simply can't get to.'
0:17:48 > 0:17:51All I can do is keep watch and wait.
0:17:51 > 0:17:54And let life in the park pass me by.
0:17:54 > 0:17:57BIRDS SQUAWKING
0:18:08 > 0:18:10They always turn up sooner or later.
0:18:16 > 0:18:19Living alongside tigers for as long as I have,
0:18:19 > 0:18:22means you notice the smallest of detail.
0:18:25 > 0:18:28I have a theory that when a tiger licks its paws,
0:18:28 > 0:18:30it's preparing to hunt.
0:18:30 > 0:18:32This could be a good sign.
0:18:33 > 0:18:38It's been many days now, but I still haven't seen Baghani make a kill.
0:18:42 > 0:18:44With no tigers to hunt them,
0:18:44 > 0:18:48Sariska's deer herds have increased in size dramatically.
0:18:50 > 0:18:55But bigger herds mean more eyes to watch out for hunting tigers.
0:18:55 > 0:18:58And that makes them more difficult to catch.
0:19:06 > 0:19:08Yet another problem for Baghani.
0:19:21 > 0:19:24I'm desperate to see her catch something
0:19:24 > 0:19:27so I can be sure she's getting enough to eat.
0:19:39 > 0:19:43These are young deer and they've never seen a tiger.
0:19:44 > 0:19:46They might be easier to catch.
0:19:56 > 0:19:58She's perfectly placed.
0:21:05 > 0:21:08BIRDS CALL
0:21:08 > 0:21:11TWITTERING AND BARKING
0:21:20 > 0:21:22Has she got one?
0:21:25 > 0:21:30Yes! At last. I know for sure she is feeding.
0:21:35 > 0:21:37It's only a small meal,
0:21:37 > 0:21:41but it gives me great confidence for the future of Baghani and Rajore.
0:21:46 > 0:21:49The scientists and park wardens have also confirmed
0:21:49 > 0:21:53that both tigers are now hunting regularly.
0:21:55 > 0:21:58They've also discovered evidence that the park has changed
0:21:58 > 0:22:01since the tigers arrived.
0:22:01 > 0:22:03Before the tigers' return,
0:22:03 > 0:22:07jackals, hyena, vultures and other scavengers,
0:22:07 > 0:22:10like wild boar, thrived.
0:22:22 > 0:22:25All thanks to the messy eating habits
0:22:25 > 0:22:28of the bold and booming population of leopards.
0:22:32 > 0:22:37With no tigers around, the leopards stopped hiding their kills up trees.
0:22:42 > 0:22:44And they began hunting in daylight.
0:22:45 > 0:22:48Very unusual for leopards.
0:22:53 > 0:22:55I've filmed leopards many times,
0:22:55 > 0:22:59and they've always avoided tigers by hunting at night
0:22:59 > 0:23:01or retreating to higher ground.
0:23:05 > 0:23:08But today, watching this one,
0:23:08 > 0:23:11it's almost as if it knows something has changed.
0:23:11 > 0:23:13It seems nervous.
0:23:20 > 0:23:25And that night, the remote cameras reveal a leopard hunting.
0:23:25 > 0:23:28Could the leopards be shifting back to their old ways
0:23:28 > 0:23:30to avoid the tigers?
0:23:47 > 0:23:51A hyena finds the leopard's kill unguarded
0:23:51 > 0:23:54and claims it by scent-marking.
0:24:01 > 0:24:03LEOPARD GROWLS
0:24:23 > 0:24:25The following morning,
0:24:25 > 0:24:29there's a reminder of how aggressive a leopard can be.
0:24:33 > 0:24:35The hyena is dead.
0:24:35 > 0:24:38FLIES BUZZ
0:24:43 > 0:24:46Not killed for food.
0:24:46 > 0:24:49The leopard has done this to show who's boss.
0:24:49 > 0:24:51A dangerous enemy.
0:25:01 > 0:25:03It's October.
0:25:03 > 0:25:07As the cool weather arrives, I'm keen to see if Rajore
0:25:07 > 0:25:10and Baghani have paired up.
0:25:16 > 0:25:19Love seems to be in the air for many of Sariska's animals.
0:25:21 > 0:25:25Winter is the breeding season here.
0:25:40 > 0:25:43Rajore wanders further in the cooler temperatures,
0:25:43 > 0:25:47so I'm hoping he'll have a chance encounter with Baghani.
0:25:48 > 0:25:52Unless these two tigers meet up this project will fail.
0:25:54 > 0:25:58But this morning, the gods are with me.
0:25:58 > 0:26:00I find Rajore following Baghani's trail.
0:26:08 > 0:26:10And I can't believe my luck,
0:26:10 > 0:26:14when I see Baghani has also picked up his scent.
0:26:18 > 0:26:20Baghani pulls this funny face
0:26:20 > 0:26:24because she uses her mouth as well as her nose to smell.
0:26:30 > 0:26:32And then she scent marks.
0:26:32 > 0:26:36It's a tiger equivalent of texting to say, "Let's meet up."
0:26:59 > 0:27:03Could I be close to getting my first shots of the young couple?
0:27:11 > 0:27:15But my heart sinks, as Baghani gives up the trail.
0:27:19 > 0:27:22Perhaps she's not yet ready for a relationship.
0:27:25 > 0:27:27My suspicion is that she doesn't feel safe
0:27:27 > 0:27:30and secure enough to think of cubs.
0:27:32 > 0:27:34She's still settling into her new home.
0:27:41 > 0:27:43Over the next few months,
0:27:43 > 0:27:46I follow the tigers as they continue to grow in confidence.
0:27:46 > 0:27:49ANIMALS CALL
0:27:49 > 0:27:52The forest alarm system often gives them away.
0:28:09 > 0:28:14Today, Baghani is near the abandoned village water tanks.
0:28:18 > 0:28:21Tigers like to cool off after they've eaten
0:28:21 > 0:28:25and this seems to be Baghani's favourite place to take a dip.
0:28:35 > 0:28:37She has another favourite spot,
0:28:37 > 0:28:41an area of dense undergrowth where she goes to eat grass.
0:28:44 > 0:28:47It helps digest all that meat.
0:28:47 > 0:28:50Even tiger's need fibre.
0:28:56 > 0:29:00Baghani's becoming as confident and settled as she was in Ranthambore.
0:29:04 > 0:29:08Over the next few weeks, I find that I am returning again
0:29:08 > 0:29:10and again to the same area of the park.
0:29:27 > 0:29:31Baghani seems to be making this patch of grassland her home...
0:29:32 > 0:29:34PEACOCKS CALL
0:29:34 > 0:29:36..in spite of the peacocks.
0:29:36 > 0:29:39I guess she's used to them now.
0:29:46 > 0:29:50It's a good sign, there's plenty of food and water here
0:29:50 > 0:29:53and places for hunting tigers to hide.
0:30:01 > 0:30:03There are many wild boar too.
0:30:11 > 0:30:15Personally, I'm more frightened of boar than of tigers.
0:30:22 > 0:30:25They can inflict vicious wounds with those teeth.
0:30:29 > 0:30:32A few months ago I think Baghani would have been too nervous
0:30:32 > 0:30:34to tackle such dangerous prey.
0:30:57 > 0:31:00To see a tiger hunting boar is extremely rare.
0:31:02 > 0:31:06To capture it on camera is virtually impossible.
0:31:22 > 0:31:24But Baghani takes me by surprise.
0:31:40 > 0:31:44I'm worried, she's taking a terrible risk.
0:31:50 > 0:31:56But as I watch, I see a new Baghani, a changed tiger.
0:31:56 > 0:32:00This one is the master hunter I knew at Ranthambore.
0:32:05 > 0:32:09She carefully moves her tail round the grass stems to ensure
0:32:09 > 0:32:10she makes no noise.
0:33:56 > 0:34:00Surely nothing can stop her now.
0:34:12 > 0:34:16The fact that Baghani leaves her kill shows her confidence.
0:34:18 > 0:34:21There is no-one who would dare take it.
0:34:21 > 0:34:24This really is her territory now.
0:34:31 > 0:34:34I think she's ready to be a mother.
0:34:43 > 0:34:47With the arrival of the rains, the park changes once more.
0:34:49 > 0:34:53I'm starting to feel as at home here as Baghani and Rajore.
0:34:53 > 0:34:57I'm really getting to know Sariska's wildlife.
0:35:02 > 0:35:06Today, the villagers' cattle are being moved out.
0:35:09 > 0:35:11Rajore has been seen hunting them.
0:35:12 > 0:35:15If the tigers kill the villager's precious cattle,
0:35:15 > 0:35:17the villagers might kill the tigers.
0:35:30 > 0:35:35I find Rajore a little later, blissfully unaware of the trouble
0:35:35 > 0:35:39he's caused and the danger he could face from angry villagers.
0:35:45 > 0:35:47Like Baghani he's now confident enough
0:35:47 > 0:35:50to leave his meal here until tomorrow.
0:35:55 > 0:35:58After all, who would dare steal his dinner?
0:36:09 > 0:36:13I return to Rajore's uneaten kill the following day,
0:36:13 > 0:36:15to find it has been claimed...
0:36:18 > 0:36:20..not by the crocodiles...
0:36:25 > 0:36:27..but by Baghani.
0:36:29 > 0:36:32And now she's got it, she wants to keep it.
0:36:51 > 0:36:56Burying the entrails will help keep scavengers away.
0:37:07 > 0:37:11A tiger would usually cool off in the water after eating.
0:37:15 > 0:37:17But not here.
0:37:26 > 0:37:29She'll just have to sleep it off instead.
0:37:48 > 0:37:51But the noisy langurs won't let her rest.
0:38:10 > 0:38:13And the crocodiles have their eyes on her lunch.
0:38:49 > 0:38:53So she decides to move the carcass out of reach.
0:39:03 > 0:39:06Finding her with Rajore's kill is a good sign.
0:39:12 > 0:39:15Tigers don't usually share their meals.
0:39:15 > 0:39:17This might mean something's up.
0:39:29 > 0:39:34Soon there are calls echoing round Sariska that confirm my suspicions.
0:39:34 > 0:39:39TIGERS CALL
0:39:43 > 0:39:45This is a tiger love song.
0:39:50 > 0:39:53Male tigers roar to call to females.
0:40:00 > 0:40:03And females roar to announce that they are ready to mate.
0:40:12 > 0:40:15Rajore has wandered into Baghani's territory.
0:40:20 > 0:40:23He must know she's close by.
0:40:39 > 0:40:42Acting this laid-back, tells Baghani he's not a threat.
0:40:52 > 0:40:54She seems impressed.
0:40:54 > 0:40:58This is the first time in seven months I've seen them together.
0:41:25 > 0:41:29A quick peck on the cheek from Baghani.
0:41:36 > 0:41:38But Rajore still plays hard to get,
0:41:38 > 0:41:41after all this is a first date.
0:41:45 > 0:41:49Rajore and Baghani stay together for three days
0:41:49 > 0:41:53and showing Baghani around is an important part
0:41:53 > 0:41:55of Rajore's courting technique.
0:42:04 > 0:42:07This is his favourite waterhole.
0:42:09 > 0:42:13And a dip in the pool is guaranteed to impress.
0:42:21 > 0:42:23Followed by a romantic walk in the park.
0:42:38 > 0:42:42Tigers form a close bond for the few days they are together.
0:42:52 > 0:42:57It's not just about sex. I think tigers get lonely.
0:43:14 > 0:43:17I can only hope that this might be the moment
0:43:17 > 0:43:20when a new dynasty begins.
0:43:35 > 0:43:38But there are still threats in Sariska.
0:43:41 > 0:43:47In the last few months, I've seen fewer leopards hunting in the day.
0:43:47 > 0:43:49But they're still here at night.
0:44:12 > 0:44:15This mother leopard could still be a danger
0:44:15 > 0:44:17to any cubs Baghani might have.
0:44:29 > 0:44:32Later she's caught again on the remote camera.
0:44:38 > 0:44:41She's killed a deer for her own cubs.
0:44:48 > 0:44:52After feeding herself, she drags the body clear of the entrails.
0:44:54 > 0:44:57And then carefully covers them.
0:45:03 > 0:45:06She's stealing prey from Baghani's territory.
0:45:17 > 0:45:22The following morning the mother leopard is out in daylight.
0:45:26 > 0:45:29And I catch Baghani heading up to her den.
0:45:38 > 0:45:40She scent marks.
0:45:46 > 0:45:50It's a tiger challenge to her big cat rival.
0:46:01 > 0:46:06The leopard is cornered - at least she's the better climber.
0:46:16 > 0:46:19I can just see Baghani at the foot of the tree.
0:46:33 > 0:46:37Baghani and the leopard remain in this stale-mate the whole day.
0:46:39 > 0:46:42I don't know what's going to happen.
0:46:42 > 0:46:45I've never seen anything like it.
0:47:01 > 0:47:06As night falls I have to stop filming and leave them to it.
0:47:15 > 0:47:18Perhaps the remote cameras will reveal something.
0:47:27 > 0:47:29A brief glimpse of the leopard.
0:47:33 > 0:47:36And Baghani following her.
0:47:40 > 0:47:43Park officials are on the leopard's trail too.
0:47:43 > 0:47:46- This here is a foot mark.- OK.
0:47:48 > 0:47:51Following her footprints and Baghani's.
0:47:55 > 0:47:58This is the leopard print here.
0:47:59 > 0:48:03I pray that Baghani is all right.
0:48:06 > 0:48:09And then they make a grizzly discovery.
0:48:11 > 0:48:14The leopard is dead - killed by Baghani.
0:48:16 > 0:48:19There's no longer any doubt.
0:48:19 > 0:48:21She's top cat in Sariska now.
0:48:34 > 0:48:37There's still no sign that Baghani is pregnant.
0:48:47 > 0:48:50We're all desperate for her to produce cubs...
0:48:53 > 0:48:57..but her first mating was unsuccessful.
0:48:58 > 0:49:01She'll be coming back into season soon
0:49:01 > 0:49:05and I've seen Rajore close by for several days.
0:49:22 > 0:49:24He's spending a lot of time at the waterhole.
0:49:24 > 0:49:27and the remote cameras reveal who he's sharing it with.
0:49:39 > 0:49:42But they also reveal a worrying sign.
0:49:43 > 0:49:46The villagers and their cattle are back.
0:49:48 > 0:49:50I hope Rajore will not be tempted.
0:50:02 > 0:50:05Baghani's ready to mate again.
0:50:05 > 0:50:09She's spent all morning calling for Rajore.
0:50:21 > 0:50:24But so far there's no reply.
0:50:29 > 0:50:33When he doesn't appear for three days, we all join the search.
0:50:36 > 0:50:39Picking up his trail,
0:50:39 > 0:50:42following his footprints.
0:50:48 > 0:50:51We're all worried.
0:50:58 > 0:51:01And then we find him...
0:51:01 > 0:51:03dead.
0:51:14 > 0:51:16Not killed by poachers...
0:51:18 > 0:51:21..but poisoned by a villager, protecting his cattle.
0:51:33 > 0:51:36But Baghani doesn't know her mate is dead.
0:51:40 > 0:51:42She's still searching for him.
0:51:55 > 0:51:58She can smell him but he's gone.
0:52:06 > 0:52:09She cries for three days after his death.
0:52:18 > 0:52:21We are both heartbroken.
0:52:26 > 0:52:29With only 1,700 tigers left in India,
0:52:29 > 0:52:32even the death of one is a tragedy.
0:52:32 > 0:52:34THUNDER CLAPS
0:52:41 > 0:52:44Rajore's remains are burnt.
0:52:49 > 0:52:52It's an Indian custom and a mark of respect.
0:52:56 > 0:53:01Without a male tiger, Sariska's future looks bleak.
0:53:21 > 0:53:23The monsoon arrives again.
0:53:25 > 0:53:27My mood is reflected in the weather.
0:53:38 > 0:53:42The rains make the forest inaccessible and dangerous.
0:53:55 > 0:53:59In these conditions it's impossible to follow Baghani.
0:54:01 > 0:54:05This is my last opportunity to see her for three months.
0:54:12 > 0:54:16It's been two years since I began filming Baghani here
0:54:16 > 0:54:19and it feels like Sariska's tiger project is over.
0:54:25 > 0:54:28But the scientists and the park wardens
0:54:28 > 0:54:31really want to make this project work.
0:54:31 > 0:54:34No-one is going to stand back and let this fail.
0:54:43 > 0:54:46A new male tiger is flown in from Ranthambore.
0:54:52 > 0:54:55This tiger has already fathered cubs.
0:54:55 > 0:54:57He will be Baghani's new mate.
0:55:10 > 0:55:15And as the dry weather returns some of the villagers pack up,
0:55:15 > 0:55:18paid by the government to leave.
0:55:22 > 0:55:27This could give the tigers the space they need.
0:55:36 > 0:55:40With the roads open once more, I set out to find Baghani.
0:55:40 > 0:55:43I'm desperate to see her again.
0:55:43 > 0:55:46I just hope she's survived.
0:55:56 > 0:55:59We soon find her footprints.
0:56:02 > 0:56:06And next to them, those of the new male tiger.
0:56:08 > 0:56:11BIRDS AND ANIMALS CALL
0:56:11 > 0:56:15This is a hopeful sign.
0:56:19 > 0:56:21And finally, after eight days searching,
0:56:21 > 0:56:24the forest alarm system guides me to a tiger.
0:56:26 > 0:56:28It's Baghani.
0:56:36 > 0:56:39She seems healthy and strong.
0:56:49 > 0:56:52And over the next few days, I follow her.
0:56:52 > 0:56:55It's clear that she has overcome all the obstacles here.
0:57:01 > 0:57:06She looks well-fed, confident and safe in her territory.
0:57:15 > 0:57:19A tiger who is ready to be a mother.
0:57:22 > 0:57:26Sariska's tiger conservation project depends on her.
0:57:27 > 0:57:31And I feel sure that Baghani will soon provide the park
0:57:31 > 0:57:36with its first cubs and begin a new dynasty of tigers.
