There is a world somewhere between reality and fiction. Although ignored by many, it is very real and so are those living in it. This forum is about the natural world. Here, wild animals will be heard and respected. The forum offers a glimpse into an unknown world as well as a room with a view on the present and the future. Anyone able to speak on behalf of those living in the emerald forest and the deep blue sea is invited to join.

Tiger was evolved as an ultimate solo predator.
There are only two scientific records of tigers killing adult female Indian rhinos I have come across:
1- Kaziranga in the book " Tigers Forever" a female rhino was killed by tigers ( a courting pair?) while giving birth
2-Chitwan a female rhino was killed by ( a pride of tigers? a tigress and her three grown almost independent cubs) , the rhino had a calf that is cared for by WWF
All scientifically documented attacks by lone tigers on rhinos are on calves below three years of age ( no horns yet) where tigers are the chief predator of rhino calves taking 15% of new born Kaziranga calves and 10% of Chitwan calves.
Anecdotal reports of lone tiger predation on adult rhinos are extremely rare and not accepted by scientists , forest guards,travellers, hunters, shikaris, adventure writers, observers including myself on safari trips can notice rare behaviour but before it can be recorded scientifically and peer reviewed it will not have any value.
The Cape Buffalo is the third most commonly killed prey animal in Africa after blue wildebeest and plains zebra and possibly contributes the most biomass eaten by lions all over the continent , Africa s 35,000 lions kill close to two million prey animals a year so possibly 300,000-400,000 Buffaloes so even if lone lions kill 1% of these that is still thousands a year versus certainly zero adult rhinos killed by lone tigers, so we cannot agree with you there.
Tigers are superb successful hunters whose lifestyle and environment make them chose medium sized prey for a 2-3 day feast ( adult chital, wild boar , sub-adult sambar) or a large prey for a week long feast ( adult sambar, barasingha, and nilgai or subadult gaur Buffalo banteng ) larger prey ( over 300kg of live weight or 180 kg of edible meat ) will turn to maggot soup in the tropical heat or scavenged by others before the tiger can finish it.
A lion pride on the other hand targets large animals like wildebeest, zebra, kudu, gemsbok, or waterbuck every 3-4 days, snacks of warthog , Impala, or gazelles for one meal, or very large animals like Buffalo,giraffe, elands, and subadult mega fauna when easier prey are not available.
Solo carnivores kill animals less than half of their mass ( Carbon et al.) as we see in Jaguars , leopards, cheetah, and tropical puma....temperate areas puma ( Canada and Patagonia ) , snow leopards, and tigers readily kill prey heavier than them.
Amazing predators!
LUCKNOW: Have Dudhwa tigers shunned their preferred prey - the cheetals and sambhars - to hunt the mighty rhinos? The killing of a 35-year-old female rhino by a tiger in Dudhwa national park and the subsequent eating of the carcass has raised a doubt if the behaviour of Dudhwa tigers is changing. The experts are not ready to buy the argument that the declining prey base is the reason why tigers are hunting and eating rhinos.
"If tiger population in the park is increasing, prey base can not decline," said Tito Joseph from the wildlife protection society of India ( WPSI). The tiger sneaked into the rhino rehabilitation area to kill the 35-year-old female rhino Pavitri, brought to Dudhwa in 1984 under the rhino rehabilitation programme. This was the fifth attack since November last year on rhinos by tigers in Dudhwa. In the past one year, two rhinos have been killed by tigers and one has rescued by the park administration in Dudhwa. The feline attacks on rhinos aren't rare. But, in most of the incidents, it's the cubs which are killed.
Contrary to this, it was an adult female rhino killed this time. Is it the same tiger which is killing rhinos? Is the attacking feline old? Bibhav Taluqdar, who chairs International Union for Conservation of Nature Asian rhino specialist group, said Dudhwa authorities should try to find answers to such questions in case the attacks are rampant. "It's not rare that tigers kill and eat rhino. Rhino comes as an easy hunt for a tiger who can not chase a deer," he said. http://timesofindia.indiatimes.com/city/...282354.cms
They also certainly do not only prey on "sub adult guar"
You can take a look through the tiger predation thread if you'd like and see Adult Bull guar and Adult female guar fall prey to Tigers, time and time again. I have confirmation of a female taking down a adult bull guar which i didn't believe. I even had to go to the actual photographer to get the proof because I thought it was a cow.
