a - Introduction

In 1977, 'Tiger! - The Story of the Indian Tiger' was published. I bought it a few years later. A good one, I think.

Sankhala was born in Jodhpur (Rajahstan), on the fringe of the desert. Rajahstan is derived from Registhan, which means 'land of sand'. About half of Rajahstan is part of the Thar desert. His father was a forest ranger. The area he worked in, the Aravali Hills, was famous for sloth bears and leopards. Many years later, he was appointed Director of the Jodhpur zoo.

Living in the forest in primitive conditions for extended periods of time and frequent moves from one area to another have disadvantages, especially for children. According to Sankhala, children of foresters never learn to compete in life. Poverty (forest officers do not earn a lot of money) also has consequences. Sankhala's parents had four children, of which only one could go to college. Sankhala was the lucky one.  

At college, he joined an expedition to cross the Thar Desert in the hottest month (May) as a botanist and photographer. Although the expedition didn't result in a lot of credit at college, it put him in head of the queue for selection to the Forest Service. This was quite something, as appointments in those days were given to the 'chosen few'. This was in the days Maharajahs still had quite a bit of influence.  

After college, Sankhala joined the Indian Forest College at Dehra Dun: 

" ... I have never regretted my time in the Forest Service, with it's fine century-old tradition of conservation. This training, augmented at intervals by short courses on ecology and park administration both in India and the USA, made me a purist. The unlimited opportunities of studying nature ... I only got as a forester. And above all I was able to live with tigers in the wild for days and nights on end, often in full presence of each other's presence but probably even more often in ignorance of it ... " (pp. 15).

His first posting (in April 1953) was in Bundi, a former princely State. Later, he took charge of Khaiwara, a small forest in the south-west of Udaipur. Four months later, he was in charge of a Bharatpur forest division. This posting in particular affected his outlook and career. Between 1965-1970, he was Director of the Delhi Zoo. In 1970, he was awarded the Jawarhalal Nehru Fellowship. This enabled him to increase his knowledge on Indian wildlife.

For a period of two years, Sariska and Ranthambore (in Rajahstan) were his study areas. He also studied tigers in Kanha National Park in Madhya Pradesh in 1971. This was the park selected by George Schaller in 1964-1965:

" ... I found that the information he had collected was mostly from one family of conditioned tigers, which had been provided with baits for more than one-and-a-half years. The group only included one male and was confined to a small area of 10-15 sq km. Vital aspects such as reproduction and the behaviour of a tigress and her infant cubs had not been studied in depth. Schaller's work was valuable in being the first ever to be fully recorded in the field, but it was insufficient to justify wider application. At that time the real facts about tigers' distribution, numbers and the conditions under which they were surviving in other parts of the country were not known ... " (pp. 18).

The first part of 'Tiger! - The Story of the Indian Tiger' is based on what he saw in Bundi, Khaiwara, Udaipur, Sariska, Ranthambore and Kanha in the period 1953-1972. In the second part, the focus is on the relation between tigers and humans. One chapter in this part is about the famous white tigers of Rewa. If you want to know a bit more about white tigers, I recommend Sankhala's book:

b - On tiger 'Jim'

In the fifties and sixties of the previous century, killing tigresses and collecting their cubs was a flourishing business in India. The cubs fetched $ 1.000,00 a piece in the foreign market. Sankhala proposed to introduce a system of providing a certificate of origin for the export of tiger cubs during the fifth session of the Indian Board for Wildlife in 1965. After his proposal had been accepted, the trade in tiger cubs collapsed. 

In spite of that, tigresses with cubs were still shot or poisoned quite often. One day, the Delhi Zoo, headed by Kailash Sankhala in the period 1965-1970, got a cub from Kanha National Park. Although suffering from gastro-enteritis, the cub made it. Jim, as he was named by the local politician who got the cub from villagers, was adopted by the Sankhala family. When he was about two years of age, he was moved to the Delhi Zoo.

Sankhala's first attempt to introduce 'Jim' to a tigress with a similar background from the Dehra Dun forests ('Rosy') failed. A fight erupted. Tigers raised by humans respond different than tigers raised by tigresses. They need more time to adapt to tiger society. 

Sankhala recorded lengths and weights of captive tigers in the Delhi Zoo. These records showed that white tigers often were longer, taller and heavier than others. A white male tiger at the Delhi Zoo ('Raja') was 100 cm. at the shoulder while standing. Male tiger 'Suraj', a normal-coloured tiger, was 90 cm. 

Compared to some of the tigers discussed in this thread, tiger 'Jim' was moderate in size. His standing height was 93 cm. at the shoulder and his total length (most probably measured 'over curves') was 282 cm. His weight was 426 pounds (192 kg.). 

The bond they had never was completely lost: " ... He and I do not meet as we used to do, though when I go to see him he will hold my hand in his mouth to remind me of the old days ... " (pp. 171). Here's a nice photograph of both:

c - On dholes

When studying tigers in Kanha National Park in 1971-1972, he noticed they were difficult to find when wild dogs were around. Sankhala thought the animosity created by wild dogs reduced the chances for leopards and tigers.

In Kanha, he saw a cheetal doe wounded by a pack of 18 wild dogs entering a compound. In the evergreen forests of the Western Ghats, Sankhala saw a pack of 21 wild dogs chase a sambar fawn into a deep channel, where she was killed.

In Sankhala's opinion, wild dogs do not fear other predators. At times, they will even chase a tiger from its kill or send it up a tree:

Some of us consider a lot of old stories about tigers and dholes as exaggerated interpretations of reports close to hearsay. There are no recent reports about tigers harrassed or wounded by dholes, they say. There are, however, reliable reports about dholes chased, killed and eaten by tigers.

True.

That, however, doesn't mean that all old stories about tigers and dholes are unreliable. It also doesn't mean that dholes can't be dangerous for cubs, youngsters and incapacitated individuals today:

d - Tigers and muggers

Sankhala saw a tiger crossing a river between Rajahstan and Madhya Pradesh. A mugger met the tiger halfway. Here's the rest of the story:

e - Tigers and pythons

In some time, I will discuss a few books that have reliable accounts of severe struggles between tigers and pythons. Here's two stories from Sankahla's book:

f - Conclusion

The natural world is quite something. Predators in particular as special to many. Not a few consider big cats as the culmination of evolution. Although an adult lion, tiger, jaguar or leopard is impressive no matter what, many forget that it takes time to get there undamaged. A lot of time. 

In the first months, cubs of solitary big cats often are on their own for many hours, even days. When discovered by other predators, they wouldn't stand a chance. This is without floods, thunder storms, heat waves, angry villagers and too many diseases to even start counting.

When they survive the first year, they learn what it means to be a predator eating meat only. Most of the animals they hunt, can be dangerous. This is why many of them are disabled by mom when they start hunting. When they, after a year or so, survive hunting school and graduate, they are kicked out.

The period between adolescence and adulthood is as dangerous as the first months, if not more so. Homeless and on the move all the time, they need to avoid mistakes of any kind. The reason is any mistake could be their last. Every hunt is concluded by a life and death struggle with an animal not seldom able to hurt or even kill a big cat. And they most definitely will given half a chance. 

Although some say that about half of all tiger cubs reach adulthood, others think that estimate is way too optimistic. Talking severe selection here.

Adult wild big cats, first of all and foremost, are survivors. They didn't get there by attacking animals able to kill them at every opportunity, but by thinking and learning. Trial and error. Male lions need to learn how to interact the hard way from the start, but solitary big cats often are selective and wary. As careful as it gets.  They just don't have another option, as an injury can result in starvation and death. Solitary cats need to be careful all the time all their life. Anyone who says a wild big cat is a 'coward', for this reason, is a total nitwit.

When big cats reach adulthood and a territory, they graduated. With honour and then some. This means that every discussion on intelligence is a result of a total lack of understanding. And respect. Respect they perhaps deserve more than anyone. 

Adult tigers, on account of their size and power, do not fear wild dogs. But wild dogs are great hunters and they are truly wild. They can't be 'tamed' and are known for their determination and courage. Their nickname, mad dog, is a result of their courage and their behavior, which can be unpredictable at times. Every now and then, they do something that surprises all. In times of need, they have been known to chase even tigers. When a big cat runs, he will be attacked in the way they attack a deer. A single dog is unable to seriously injure a tiger, but a pack can hurt any tiger if they decide to go all out. A suicide mission, no?

I've been in the famous zoo in the eastern part of Berlin on a cloudy and gloomy day. After seeing the big cats, we visited the wild dogs. Apart from us, there were no visitors. We were circling the enclosure, but didn't see anything. Then one of the dogs was right behind us. One yard at most. When we turned, they came from all directions. Small, they were, but they were fully alert and it wasn't a game. Did it have an effect? We had seen an Amur tigress with quite large cubs known for her temper. Her demonstration was impressive, but she was behind bars wasn't she. A good show, it was. After the dogs had talked to us, however, my companions said it was time to go. They were intimidated. By animals known to avoid humans anywhere.   

Would these mad dogs consider a suicide attack in some conditions? No question, I concluded. But that's just an opinion.

Kailash Sankhala - a side note:
I also have his book, but I almoust never use it, why? well because his conclutions are incorrect most of the time.

It is really disturbing and even silly how Sankhala discredit the studies of the "westerns" like Schaller and Seidensticker, and is not only the small paragraph that you posted, there are several times when he critizice the methods and findings of the "westerns" (including the FACT that tigers use the olfactory sense for comunication, for God's sake!!!). In fact, I know that he is part of why the mentality on conservation of tigers by the authorities in India is still so slow and even atavic, after all he was the one that stoped the first aproach between the Smithsonian Institute and the Indian Goverment. At the end, we know that the Smithsonian experts went to Nepal and it took several years since 1960 and until 1990 to start a real scientific study of tigers in India using modern technology (Dr Karanth in Nagarahole).

Sankhala's book is confusing and even dangerous to use it, it sale very weird ideas about the tiger behavior and I can even say that those same ideas were the one's presented by the chiefs of the "Project Tiger" when the Sariska tiger dissapeared. In fact, the same stupid ideas that tigers are not territorial and that they "migrate to the mountains", that were used to justify the dissaperance of tigers in Panna and Sariska by the people of the Project Tiger, were first stablished by Shankala. The conclusions about the territoriality of tigers in Ranthambore are completelly different from those of the longer and more accurate observations of the great Valmik Thapar. IF you read Thapar, Schaller, Sunquist and Chundawat, and latter you read Sankhala, is like if they are talking of two completelly different animals!

For this, and other reasons I don't believe that Sankhala's book is a good source on tiger behaviour, altough some information about reproduction and feeding intake from his captive tigers was quoted by Dr Sunquist, but just that. In fact, his recalcitrant and highly burocratic point of view infected the Project Tiger so strongly that even in modern times they continue ignoring the modern results on tiger ecology based in scientific develpment. In fact Dr Karanth state that: "We both continue to strongly belive that the scientific process of per review and publication in high-quality journals should guide the choice of appropiate methods for monitoring tigers and their prey. Therefore, we are somewhat dismayed that, in spite of availability of superior methods, tiger conservation practitioners are sometimes slow to adopt them or even use demostrably flawed or obsolete methodologies. We believe this is largely because of intellectual inertia, rather than resource constraints, given the current levels of investments. Unfortunately, we can offer no methodological cure for this problem." (Karanth & Nichols, 2017 - Preface). If you ask me when this flawed metholodolgies started, I can tell you that part of that started with Sankhala, that is for sure.

Despite his good intentions and the fact that tigers are still in decent numbres in India because of the initial efforst when he was included, Sankhala point of view on tigers affected its conservation at future level, as India have many small pockets of not interconnected tiger habitat, that altough is good to save it for the short term, it is very problematic for the survival of the tiger in the future. I think that if some one should have called "The Tiger Man of India", that should be the great Valmik Thapar, which not only made good personal investigations with national naturalists, but also blended succesfully the studies of those "westerns" scientists which methodologies, at the end, are the ones that are also saving tigers in Nepal, Russia and Thailand, despite its smallest territory or lower prey base.

On the Dhole issue:
About the tiger and dhole interactions, it is interesting to see that he don't saw any fight or type of conflict. In fact he concluded that the tigers leave the area because the dogs put all the prey in the area in alert status, which is exactly what the tiger don't want (tigers prey by ambush, and when a serial of unsuccesfull attempts but the prey on alert, the tiger move from the area). Also is interestingly that when he says that tigers can killed and eated by dholes, he relay in the "early-twentieth-century paintings" (are he serious?) and by "recent" observations (which?).

Again, Sankhala do not present direct evidence of dhole predation on tiger, nor even conflict, just a logical avoidance based in the fact tigers been ambush predators can hunt with high alarmed prey.

Valmik Thapar in his great book "Tiger the ultimate guide" also quote four events of tiger and dholes (page 136 - 137), one of them is the report of Kenneth Anderson, the second is one of W. Connell (JBNHS IN 1944) where he said that a tiger (no sex or age) was attacked by a pack of 22 dholes, at the end the tiger was killed and eat but he killed 12 of them (half of the pack for one meal?). The third event is reported by Colonel Kesri Singh which in the book "The Tiger of Rajasthan" (1959) describes an evening when a tiger feed on a sambar for nearly 30 minutes but when he listened the cries of the dholes, the tiger started been anxious and uncomfortable but state in its ground. At the end the dholes arrived and surronded him, the tiger growled and the dogs whimpered, the tiger striked a couple of the dogs but at the end decided to flee, the dogs stay there and eat the sambar, they did not followed the tiger, again no age or sex was described and this sounds more like a young tiger, but is my speculation. The forth event is quoted from the BBC television series "Land of the Tiger" and includes a footage shot in Kanha National Park in 1997 when a tigress chase away a pack of dholes and appopriate the kill. These four events are the only thing that Thapar mention about the tiger-dhole conflict.

I want to make clear that Dr Karanth, nor I, are saying that the report of Kenneth Anderson is fake, he only says that maybe somewhat exagerated and the fact that there is no case of dholes attacking (actually attacking) adult tigers during more than 50 years of scientific study, put some doubts to the reputation that the dhole have in India. It seems that, following Mazák, an adult healty tiger is out of the predation range of any dhole pack, but a young and unexperiance tiger, or a week, injured or very ill one can be killed by a large dhole group, not without heavy losses. But this is a thing of the past now.

Guate, forgive me but I think you have not authority do judge such a remarkable scientist as Dr Kailash Shankala, an icon of "Project Tiger". While you no doubt are good poster, your background has nothing to do with biology, but more to do with business or computer sciences. If businessmen start teaching biologists and dentists start to teach nuclear physisists this is the sure way of collapse of the civillisation.

Nevertheless, I like and respect you because you sincerely love tigers and in general our views in all other topics are 99% similar if not identical.
Ok, nobody rejects the fact that in last 50 years a carcass of killed by dholes was not found. I think a topic "tiger VS dhole" should be temporary frozen by mods until more new and fresh information comes, as pointed Rishi. Otherwise wildfact will slip to civil war and finally collapse. Topic "tiger VS lions" was  frozen as too dangerous, I think same have be done with "Bear VS tiger" and "Tiger VS dholes".
