Tigers of Ranthambore & Western India Landscape

Clicked in mid-2018, this tiger family is T59 female (Alcmene), probably the shyest female of the park, T62 male, very rarely seen himself (Ladla, son of Ladli) and their two 10 month old cubs in Zone 9 of Ranthambore and are the least photographed family of the park.

T-62 is the son of T-34, Kumbha and brother of T-43, Surzan. He fled to Bundi Forest in 2013 when he was 2.5 years old due to the threat from his brother and father and another dominating tiger in the area, T-42, Fateh. However, he returned in 2016 and claimed his territory from Fateh.

One of the cubs in the picture is T115. As continuation of the post #344, this is the same cub who has migrated to Bundi and he is 3 years old. JUST LIKE HIS FATHER. 

That is such a fascinating behaviour. Maybe he too has migrated in order to build up himself before he returns to claim a territory when he is in his prime.

Rajasthan has more inbred tigers than any other state in India: Research
The National Centre for Biological Sciences team has been using hair, blood, tissue and muscle samples from the big cats to create their genetic database and pedigree in Rajasthan.

Rajasthan has more inbred tigers than any other state in the country, ongoing research by the National Centre for Biological Sciences (NCBS) has found.

Anubhab Khan, one of the researchers who is a part of the NCBS team, said the reason behind the inbreeding—producing offspring from mating or breeding of individuals or organisms that are closely related genetically—in Rajasthan because of their isolation.

“Tigers from here have dispersed up to 150-200 km towards Madhya Pradesh, but there aren’t any reports of any coming to Rajasthan from other states,” Khan said. “We have sequenced tiger genome across Rajasthan. Here, mostly the tigers have dispersed or shifted from the Ranthambore Tiger Reserve (RTR) to Sarika Tiger Reserve (STR) in Alwar and Mukundra Hills Tiger Reserve (MHTR) in Kota. This shows that all the Rajasthan tigers are related.”

The NCBS team has been using hair, blood, tissue and muscle samples from the big cats to create their genetic database and pedigree in Rajasthan.
“In the six-year-long study, we have collected blood samples (besides tissue and muscle samples) from 18 dead or tranquilised tigers, and hair sheds of 34 tigers,” he added.

Khan said the study of tiger genome through its hair is a faster and reliable method. “Earlier, we had to wait for a tiger to get tranquilised, but now we just need to follow the tiger and wait for him to sit,” he said.

The researchers, so far have studied 60 tigers from eight states of Rajasthan, Tamil Nadu, Kerala, Karnataka, Assam, Madhya Pradesh and Maharashtra. Khan said the study was useful in numerous ways. For example, he said, that if a tiger is to be shifted from Ranthambore to Mukundra, the sequencing of its genome will help identify the RTR big cat—not related to any other such animal in MHTR—that can be sent there for better reproduction.
“Mitochondrial (related to cell) lineage can also be studied. During the study, we found that T-47 (a tiger) whose parents were not known is from the family of Machli, the longest surviving tigress,” he said. Emphasising on the need for outbreeding, RTR field director Manoj Parashar said it has been seen everywhere as the tiger population is isolated. It’s the tigers from RTR, which have gone to Sariska and Mukundra. There are zero possibilities that any tiger from outside comes in contact.

“Inbreeding is an issue, but it has not affected the population figure of tiger,” he said. Parashar said the research is ongoing and the report is yet to be submitted.

A senior forest official, who did not want to be named, said in order to avoid inbreeding and create a fresh gene pool of tigers, the forest department in Rajasthan is mulling bringing 2-4 big cats from Madhya Pradesh under the tiger reintroduction programme to the Sariska Tiger Reserve. Sariska has 20 big cats—11 females, 5 males and 4 cubs.
The officer also pointed to the need for a fresh gene pool of tigers. “In the case of the death of tiger ST-16, cancer was suspected. The disease is indicative of inbreeding, which also could be a cause of infertility,” the officer said.

Behzad J. Larry: " T-104. Ranthambhore, India.

I’ve posted a bit about this tiger before. Once a tiger is identified in India’s national park systems, it is given a number within that national park. This is Tiger 104 in Ranthambhore. He’s a controversial figure, having killed three people, in search for territory outside the constrains of the national park. Now he’s in an enclosure away from the public eye while the powers that be decide his fate.
He’s not roaring or showing aggression, but rather the flehmen response, which facilitates the transfer of pheromones and other scents into the vomeronasal organ (VNO, or Jacobson's organ) located above the roof of the mouth via a duct which exits just behind the front teeth of the animal. "

Sachin Rai: " Argument! These siblings had reached a stage where they were growing short of patience to tolerate each other. Made this in Ranthambhore 5 years ago. Ironically, the girl who’s snarling is ruling this area now.

Btw, the light on her face is natural and not added in photoshop ?. "

At mukundara hills tiger reserve day trade in new method of relocation, by sensing of 84 square kilometre of forest as 100% inviolate zone for the pair to settle in... Ranth's T-91 (MT-1) was released inside that, but T-98 (late MT-3) came by himself & lived outside the enclosed area.

In this video by Dharmendra Khandal, you can see them in both sides of that fence.

The total tiger population in MHTR rose to 6 including the newborns of MT-2. That's back to 5 after death of MT-3.

There were indications that tigress MT-4 and tiger MT-3, who are outside the enclosure mated, but so far it has not resulted in any cubs, yet... Let's hope MT-4 Lightening is pregnant right now & will have cubs in near future. A tiger who was 240kg at age of 4 years, don't deserve to die without his genes passed on.

The tiger's head seems to be small. But the neck too, very short in size. Perhaps because the strength of the forelimb "overflows" the body.

David Yarrow: " The Queen Of Ranthambore⁣


Today we celebrate #InternationalTigerDay. The tiger has long been an animal associated with fantasy and fable and it is no surprise that they are many people's favourite animal.⁣

On our 1am drive back to Delhi after I took this photograph back in 2018 we did some maths. We calculated that in total we had spent 35 hours in a jeep looking for tigers and in that time, we were with tigers on our own for about 30 minutes. That equates to being employed for about 1.5% of the time and places this assignment right at the low end of what we do, along with polar bears in Svalbard.⁣

This mother of three, is well known to the guides and because tigers feel the heat just as much as we do, watering holes in the middle of the day offered the best chance of meeting her in her territory. There is a great amount of luck involved in this approach as I need to be low as well as safe and many watering holes do not allow for this. I needed the right waterhole and to be there at the right time. She also needed to face me - and that in itself was against the odds.⁣

On this occasion, I was able to get very low and she confronted me head on. The shadowed ripples of water fuse with her stripes in a manner I could never have preconceived. The 98.5% of gruelling torture was made totally worthwhile by this special encounter. "

Ok, one good news is that MT-3 managed to pass on his genes. MT-4 (aka Lightening) had given birth to cubs several weeks ago.
