Tiger Conservation: Story of Breeding Tigers and Territory Take Over

In all my years as a naturalist in India, I have realized that tigers are prolific breeders. Their life cycle is fine tuned to an extent reaching biological perfection only seen among the wild species and certainly not among humans and their livestock. 

Long time back in the forests of Kundam Range near Jabalpur in MP, I stayed awake listening to the mating cries of tiger pair from the Rest House at Kundwara. Aaaaaaaaaaoooooooooon!Aaaaaaaaaaaaooooooon!

Having seen them earlier it was a dream come true to hear this magical sound. The big cats were breeding in a badly denuded ecosystem outside a protected area.  

Working as a naturalist, I had learned to recognize some sounds emitted by the big cats few among a mind boggling repertoire. Sleep took over amidst feeling of extreme euphoria naturally!

I have not been to the forests of Kundam again and do not know the state of conservation of these big cats in an area not at all under strict protect and subject to poaching and pilferage. A visit will certainly enlighten you as regards the deprecation of forests on Central Indian Highlands.

The breeding pair would have certainly mated and given birth to young ones. Unfortunately no news percolates about the status of reserved forests outside the PA or the popular tiger reserves/National Parks.

This vast stretch of forests is home to a small prey base, few reptiles like the marsh crocodile and plenty of livestock. It does not form a perfect corridor anywhere since a large number of human settlements have creeped in since ages. Now the urbanization is taking a heavy toll and in few years perhaps only remnants would be found as evidence of once intact ecosystem.

The nightly incidence was an eyeopener how the big cats find each other for mating otherwise solitary. The other means of location is spraying of pheroharmone especially among dense populations like in some of our reserves. Sound is a greater facilitating factor among sparse populations. But these could be a giveaway to poachers.



Another meeting point among the cats separated by a large distance is search for water where they can congregate in summer. Unfortunately most of the water bodies are surrounded by human settlements and hence are completely out of reach or only accessible during the night. Hence all forests in India should comprise of an inviolate core however small out of reach of humans but this is wishful thinking. 

The big cats usually start breeding whence they become adults. Females are ready at the age of two and half years and the males whence nearing their fourth year. The males can breed easily by the time they reach their fourth year or earlier depending whence they have ousted the dominant male there. They are at their peak strength at four years and can manage to dislodge a ruling male. And this is usually a violent take over with the killing of cubs sired by the earlier male. This hence brings the cub survival rate down by fifty percent in the protected areas. 



In areas outside the PAs with few intruding males survival could be hundred percent but then we have to take into account lack of prey base, limited area and constant threats from humans as a limiting factor.  This can have a negative impact on breeding.

The worst threat for these predators in unprotected areas is due to man animal conflict whence the cattle killed by them is often poisoned. A livestock kill is also a giveaway as an evidence of presence of the big cats in the neighboring settlements. In modern times we have increased intolerance for the predators. The consternation leads to translocation or killing of the animal for example sometimes leopards are mauled by large gatherings out of fear. 

Mating is a noisy affair and rarely witnessed since the couple move into dense confines to avoid disturbance. The gestation period is of ninety days on the average.

The female during the estrous would mate with the dominant male but then she could be mating with intruders as well in order to achieve the best genes. Polygamy also insures greater safety for the progeny as other males take the cubs to be carrying their gene.

Even when the female is with growing cubs she can falsely lead the intruding male away or go in for false mating in forced circumstances where in conception does not take place.

But young cubs from a dominant male are usually killed on encounter with an intruder whence he manages to creep in. It is up to the capability of the mother to save as many as she can. Males are stronger and can overpower females on many occasions. They have been found to kill females not willing to mate or whence defending their cubs. The dead are consumed not because of being cannibals but due to the fact that in the wild no valuable protein is left to rot!

The litter size is of four cubs but two or more can also be the case but rarely. From three months onward the cubs start moving along with their mother as it is a learning phase. They have now started to eat meat and quickly learn the purpose of their existence at the top of the food chain.

Learning is in phases. They become familiar about the terrain as they move along and then the mock fighting begins eventually learning to hunt after one year as spectators. In very late stage they learn to kill a badly mauled fawn or a small wild boar etc. Following this they eventually learn to kill by the time they have to separate from their mother two year onwards.

After separation the cubs form a group as they have still not mastered the art of hunting hence kill together. They linger on in their mother's territory or adjacent forest protected by the male who has sired them. But as they become confident separation is evident.

Female make their territory with the mother's space on in nearby confines. The males move further and are constantly in process of creating their own space in areas with sparse population of their brethren. Using chemical signals they carve out a space with very little presence of a foreign intruder.

In Kanha empty spaces are filled by young males using chemical signals till they are about four years and at the peak of their strength. They rarely challenge their father and the conflict is usually with a male in the area they have been pushed into. 

Territory take over is a constant process but rarely based on impulse. An impulsive move usually leads to death at the hands of the dominant and experienced male. In order to avoid bloodshed, detrimental to healthy population, often males are seen in the same area avoiding conflict using their spacing instincts. Presence of many males in a given area assures conception perhaps with the best gene.

A new territory takeover is announced by extensive vocalization. A hold on territory is usually for four years or more but by this time sidelining of dominant aging males is evident.

An exceptional hold on territories was held by legendary Munna male who successfully moved to takeover adjoining areas whence dominated in erstwhile territory. He ruled over parts of Kanha core for perhaps sixteen years before being finally relegated to the buffer. He is now in Bhopal Zoo. He is perhaps the oldest living Bengal tiger in the wild in India.

Conflict is not deadly on the first instance but usually begins with a roaring match if that does not settle the matter a push and pull plus sparing has been observed. This will usually mark out who the boss is and if not the fight to death occurs usually by serious injuries or sometimes a straight kill.  A young male tiger was killed by a dominant upon intrusion. The fight was supposed to have raged over night and the young male was eventually killed and eaten.

Breeding Tigers!

Guests Colin & Lynn & Family : Angela UK
Courtyard House Kanha

Banno Cubs!
Tiger - Uday Patel 

Reaching the spot where we missed seeing two tiger cubs a day before was again a disappointment. But I had decided to keep the spot under the scanner. So as always happens we began exploring the nearby area for the tiger frequents. The male tiger was nowhere and we moved back again there was no sign of the cubs....disappointment. Have they moved away as predators always do...   

Tracking tigers is a game of patience and logical thinking, and it tests your skills using the sensory apparatus. We were waiting at the nearest crossroad since all the jeeps had exhausted their search for the cubs at that spot and there was no hope. The waiting made me think. Yesterday whence we had missed the cubs there was no sign of the mother. Today also she was untraceable...that meant she was probably out hunting as six months old tigers could have a voracious appetite. So I began speaking to the guide explaining to him that since the mother was not around for two days the cubs would probably be there hidden in the bushes at the same spot.  A questioning look on his countenance made me speak further. 

"The cubs would not move without their mother or until unless she calls them," I said.

This was unlikely to have happened. So I decided to station our jeep near the spot and not at the crossroad planning for a search elsewhere. As we were reversing...on the rock sitting silently was a tiger cub staring curiously right at me the jeeps having gone it felt reassured to savor the warmth of the rock heated by the emerging sun. It had rained the previous night and hovering clouds made the matter worse. 

"Back," I shouted." 

The cub kept on looking at us curiously and a bit surprised. He changed his stance and angle to have a good look at us. Oh! "Mother never told of this weird animal!"  

My guests could photograph it well before the arrival of the second jeep pushed it back into the rocky bush never to emerge.        

This tigress had two cubs aged six months. Banno is one of the shyest animals in the park, and I have been spotting her paw prints for the last two years but could never see her.   

Breeding Tigers 



Kanha National Park has provided an excellent breeding ground for the big cats...but in my years of searching for tigers, I have always found the cubs within the periphery of the core zone. A core zone in the protected area of the tiger reserve is devoid of human settlements, agrarian activities, and trespass. 

In this area, only the staff are allowed to reside while tourists maneuver in twenty percent of the area and exit whence the time is over. This means there is little disturbance to breeding tigers from the activities of people. Surprisingly they have immense tolerance for jeeps...probably they consider it as another animal, and in time to come after frequent encounters...harmless.     

While rearing cubs the mother has to move the family frequently albeit in the territory controlled by the male whom she has mated with. Though her territory is usually small there is ample space for moving cubs from time to time to keep them safe.

In the core zone the prey base is very high and within reach. The growing cubs have to be fed frequently and the mother has to eat too frequently too. A low prey base would definitely affect the breeding.  In fact, tigers breed corresponding to the available prey base. 

Discounting internal mortality between the specie due to conflicts, predation of cubs, and breeding prerogative amongst the strongest, the survival rate is very high and at times it can be a hundred percent. This has been seen in the tourism area since the rest of the core is out of bounds for the public.   

Buffer Zone 

All this is not possible within the buffer zone of a protected area as human settlements, agriculture and commercial activities abound. Though tigers live here too, but they are there because of territorial implications. Breeding if any is surely limited.      

Big males frequent the area as some of them prefer livestock that offers more meat per kill. Females frequent areas adjoining the core but their presence is very weak as I have noted. Creating a buffer zone for tourism is a good step as it will accord additional area for the big cat movement in time to come. Unfortunately, livestock still plunders the buffer tourism areas and there is a distinct shortage of water. For the fear of poisoning by habitual poachers water holes or saucers are not created. Hence the prey base is extremely thin because of the dry terrain, water shortage, livestock grazing, and frequent human movement on foot and vehicles. 

Ironically in order to sustain tourism in the buffer zone they will have to be turned practically like the core zone. Only then the big cats will move and breed in the buffer favoring tourism as well. Till then the core will sustain breeding populations, but the extra space required for the increasing population in the protected areas is a dim possibility with the buffer being just a namesake.

Intruding Male Tigers Killing Cubs

With the sad demise of Budbudi female, her cubs would have perished as well or perhaps eaten by the intruding male tiger. An impressive number of cubs are born every year, but few survive to repopulate the reserves in India.

The males that sire the cubs do not kill them but rather protect them from attacks and often meet and share meals with the family as a matter of assurance. It is the duty of not only the female but the male as well to see the cubs through the two plus years of vulnerability.   

The territorial hold of dominant males is porous and is often intruded on by transgressing rivals. This is bound to be as male tigers are peripatetic, busy patrolling their territory leaving females and cubs vulnerable to an attack by an intruding male. It is difficult to manage large territories that the dominant cats hold. They may have mated with other females in their area in order to ensure a healthy population of their species. Darwin's survival of the fittest is very much evident in tiger landscapes where the battle for space and food is intense.    

The killing of young ones is a natural phenomenon and insures the transfer of better genes. Well, this can not be often as many times the intruding male is sent packing or is unable to kill all the cubs. Death of all the cubs could mean females coming back into oestrus. This is what the intruding males seek. By killing all the cubs they are able to transfer their genes. 

The big cats are possessive mothers and go out of their way to protect young ones. Not only protection but also impart skills for survival in the wilderness. In order to remain safe they keep on shifting their territories but the shifting process may make them more vulnerable to attacks by rival males.  

Whence the tigress is able to resist takeover it could ensue into an internecine battle often resulting in the death of the female. The male is hurt too but being stronger and larger is able to fend off death. This is what happened in the case of Budbudi tigress in Kanha National Park. The male eventually consumed the female which again is not surprising.     

Tigresses do mate with more than one male to ensure fertilization as well as avoid conflict with a rival. This often happens whence the males are siblings and hence allowed to stay in the vicinity. The big cats show greater tolerance towards their siblings than towards strangers.     

Within a spate of a couple of months about ten cubs have been killed at Kanha National Park. This is a regular occurrence and those that have lost young cubs may soon give birth to another litter. These events certainly do not call for human intervention since is nature doing its bit.  

The loss of young ones is certainly sad since we are losing tigers fast due to other factors chiefly lack of habitat, electrocution, and poaching. But many times hundred percent survival rate is experienced in well-managed parks, and this is what maintains a population balance in the ecosystem.

The cubs are vulnerable for two years but take more time than that to learn and gather experience. This is essential to fend off dominant males hence they have to find uncharted territory. In case of space restriction, they have to face humans which are more dangerous than rival males.      

Tigers are prolific breeders and swiftly replenish their stock if adequate protection and space are provided.  Winters are preferred for mating albeit it goes on throughout the year as and when the opportunity arises. This is the period whence conflicts are accentuated including territorial fights among the males. 

Generally, the core undisturbed area is sought after by dominant males. The high prey base, water, and adequate shelter make the core inviolate area preferable to the buffer which is littered with settlements and farms.

Mating Time Kanha



The male and female tigers kept calling each other in broad daylight. We sat in our jeep waiting in expectation as the ethereal sound waves collided in our ears. The effect was magical in those serene surroundings of dense jungles of Kanha National Park.   

We were listening the mating calls of the pair hidden in the deep confines of the jungles. The pair did not emerge from the bush but nevertheless we enjoyed understanding the mating behavior of tigers. The call ceased after some time and the pair moved uphill away from us in to undisturbed area to mate in complete privacy.    

In protected areas like Kanha only the dominant male is able to mate with tigress in estrous. The competition is fierce and weaklings are pushed into subjugation. The dominance ensures transfer of best genetic trait much required for survival in wild terrain that the preserve is.   

In our tiger safari we found lot of evidence of tigers mating, some lucky one's may have witnessed this solemn event. Field biologists have understood much about breeding biology of big cats and more has to be discovered. This is required for tiger conservation in India for mating ensures arrival of new generation of big cats and hence augment numbers.      

Kanha National Park is situated in the Central Indian State of Madhya Pradesh in India. It is habitat of long lit of mammals, birds, reptiles and insects. The floral diversity is bewildering and requires training in advance botany to understand.  

Understanding our wilderness is not reserved for researchers alone, each and everyone can make a valuable contribution to save the tiger and its home. The mating increases in Kanha during the winters to some extent since the predators breed throughout the year.   

We were lucky to witness a young tigress searching for male tiger near the Kanha Meadow. The chemical communication is highly developed in big cats and they find others from scent in the urine sprayed on the trees. They also use scat and sprays on bushes to communicate. Using a process called flehmen they discover tigress in estrous or scent of the male nearby.   

The tigress sucked the effervescence of fresh urine on a Salai tree and grimaced with her tongue hanging out. The flehmen enables air to be sent to the vomeronasal or Jackobsons' organ situated in the roof of the mouth. The processing lets the big cats to discover other tigers especially females in estrous. 

My group was able to photograph this event from close. There were more tigers to be seen later besides the enchanting wildlife and avian species. 

People come from far and wide to experience this magical mystical land called Kanha. Tourism benefits wildlife and local communities in a positive manner. The preserve is the best managed in India and tourism is controlled such that it remains friendly to the ecosystem and its wild denizens. Large scale employment is generated by the hotels in Kanha which follow responsible tourism guide lines. The resorts depend upon the tourists to survive which arrive here in plenty every year.    

Best time to visit is anytime whence the park is open (16th Oct.- 31st June). Depending upon weather preference you can organize your trip. It is cold till the month of February and the heat increases after words. Avoid holidays and weekends. The park is closed for evening safaris on all Wednesdays.

Bandhavgarh: Breeding tigers

The last nights telltale event was clearly etched on the soft jungle road. The sordid saga of survival in the tortured terrain of Bandhavgarh National Park. We followed the drag marks for a long distance till they crossed over into the dense forest.  

The predator had killed a chital doe and dragged it to the spot where her cubs were located. The struggle was evident, the drag marks formed a narrow strip of depression on the road turning and twisting in a bizarre fashion. The tigress had put it all in to take the dead prey all the way along to her cubs. 

Ignoring the bitter cold of early morning we waited at a spot at Churbohera Road in expectation. The kill was probably consumed and she was likely to emerge near the rivulet or her favorite perch next to it. After some time we decided to check the large slab of igneous rock which was her favored retiring place.     

We could see nothing till two cubs decided to play. The mother had carefully placed herself behind a clump of bamboo and the cubs stayed alongside her as she lay asleep. We could see the three little tigers about 3/4 months old but it was not possible to photograph them. Kankati had at last brought her cubs out of hiding, The challenging race for survival in the wilds had begun for the cubs, the tigress will mentor and tutor them for two years before making them independent.  This is necessary since this predator is a solitary animal and does not live in pair or a pride.

It was heartening to see the cubs as they loitered around close to their mother. I had seen small cubs before but after a gap of ten years perhaps. The spectacle is a memorable event, the cubs threw a cautious inquisitive glance at us and quickly retracted behind the bamboo. The hide and seek game went along for some time before they vanished out of sight alongside their mother. They where probably seeing humans and their bizarre contraption for first time since birth.

We were on tiger safari at Bandhavgarh National Park - me and my French group.  We saw more than the tigers - birds and mammals - a successful nature photography tour. Bandhavgarh is a prime tiger habitat in Central India with high rate of success in breeding. I could find evidence of about sixteen cubs in the park during my visit from 20th November to 23rd November. A new generation of tigers was emerging in this nature preserve auguring hope for the survival of its race. Sound policies, effective protection and positive conservation may fetch this species from jaws of extinction in the country.   

There was a mother with four cubs at Tala Zone on a kill. We could hear the squealing and mock fights but failed to see them. A just delivered litter of four was discovered in Magdhi Range besides sighting of tigress with three cubs probably 6/7 month old. Three cubs were seen on Mahaman Road by the guards. 

There may be more breeding tigresses in this little paradise. This augurs hope for the tiger's survival in India - thanks to good conservation measures. The topography of this park provides excellent security and privacy to the tigers besides a good pray base. Most of the hillocks in the preserve are inaccessible and provide safe breeding grounds for the pregnant females. Unfortunately there is disturbance in the buffer and the periphery of the core due to number of villages and livestock.     

Inbreeding threat exists in all the tiger reserves of Madhya Pradesh since they are no more interconnected with each other. A viable corridor is a must for gene transfer, this relates to all reserves in India.

It is Now or Never

Tigress & Cub Mr. Navneet Maheshwari
Chimta Camp Kanha National Park MP India

This tigress with cub was captured in camera by Mr. Navneet Maheshwari the owner of Kanha Village Eco Resort. The property is luxurious, built using guide lines of responsible tourism. The lens man is committed to nature conservation, and is an acclaimed wildlife photographer.     

The subject matter though elates is also a grim reminder of the fate of this extremely majestic animal that sits at the top of the food chain and is an indicator species. The terminology denotes a vital element, and does indicate the impact of constructive or destructive activities in an ecosystem. The tiger's absence from tropical forests in India is suggestive of a badly fragment ecosystem with no beneficial effect on our environment.  No rivers, no food, no water ...mother Earth without a womb. 

We have to come to understand the correlation between natural lands their vital elements and myriad life forms that play major roles to preserve our environment. This complex web of linked elements as whole are crucial to our environmental stability. When we understand this, the tiger's role on Earth becomes evident. 

Nature conservation is not an elite prerogative as many people believe, nor is love for mega fauna a fad. Nature conservation is a serious dedicated effort in order to leave a beautiful healthy and stable environment for our generations to come. Unfortunately short term goals and pecuniary greed negates all positive steps and  sacrifices humanity  has to make in order preserve whatever is left. Making amends for the continuous destruction the human society is causing today, seems an impossibility almost chimerical. But we can preserve the fragments of natural lands which are still alive, which means saving this apex creature.      

The image of mother and cub accords human touch and sensitivity. The tigress rears her cubs just as humans do with kindness and caring love. The growth is signified with intuitive development augured by the  dedicated instinctive learning process at the behest of the mother. By examples and trials. Yes just like we do for our children to survive in this rat race. The natural world is more disciplined with very little instance of aberration, yet survival instincts are ingrained and impregnated for the cubs to survive in a terrain full of natural enemies.  The limiting factors that justify the survival of the fittest.     

Will the posterity capture such images there is a big question? Only the voice for voiceless will help those beleaguered but with the right to own the Earth as much as we do.  Live and Let Live.

Tiger Cubs

This year has been good for Ranthambhore tiger reserve in Rajasthan and Pench tiger reserve (Seoni Hills)in Madhya Pradesh. Tigers are prolific breeders but the extent to which their population has been decimated in last hundred years that this fecundity is hardly noticeable.

The reckless poaching has resulted in extermination of population all over India and has even resulted into skewed sex ratio at places. Combined with stress of human interference and continued threat of live stock and prey base depletion tigers survived in reserves and bred well. There was a marked rise in population of tigers in some National Parks. But when places which are disturbed and suspected of being under attack by the poachers - as Ranthambhore - report fourteen tiger cubs being born in the park, it is indeed heartening news. This also shows that the sex ratio among male and female tigers there is in balance and mating is taking place regularly.

Similarly at Pench nine tiger cubs where born recently. Pench is an upcoming tiger reserve in terms of sighting and successful breeding of tigers has resulted in good tiger sighting in the wild in recent times.

Another benefit of larger number of tiger reserves reporting good tiger sighting is that the tourism pressure will spread even and let off some air from Kanha and Bandhavgarh. The lodges and resorts at Pench and Ranthambhore tiger reserve will also see greater number of visitors if this trend continues.

------------------------------------------------------------------------------------------------








Tiger on a kill in this case a spotted deer fawn which it had killed couple of hours ago. Tigers hunt mostly in the night but no rule hunger is hunger and it will hunt its prey any time of the day if required. Tigers ignore human beings when they are involved in an activity including rest. This is really surprising as they can be very shy and elusive at times..they are afraid of human beings.
-----------------------------------------------------------------------------------------------







Tiger are thirsty animals and drink often in a day especially after a meal as in the case of this young tiger. Tigers love water as they are incapable of standing the heat of Indian summers. They move deep into the forest and lie in a shade or dip in a water to cool themselves ...this is known as thermo regulation.
