Tiger Predation

I have always read that Southeast Asian gaur being the largest, superficially if only looking at the photo this could be deceiving because South Indian gaur has the largest dewlap so it looks gigantic compared to others, for sometime i have come to distinguish gaurs from different regions:
South-east Asian gaurs: 1, very dark coat almost jet black, including cows and calves are much darker 2, darker muzzle or nose 3, have relatively yellow legs and sharply contrasting black tipped horns  *This image is copyright of its original author South-Indian gaur: 1, dark brown hide/coat for males, female and calves brown 2, largest dewlaps i have ever seen 3, definitely has paler or grey muzzle  *This image is copyright of its original author Northern Indian or Nepalese gaur doesnot normally has a large dewlap like South-Indian ones  *This image is copyright of its original author these are what i see, sometimes these features can overlap but for the most part it is pretty clear  (09-14-2018, 05:38 AM)Roflcopters Wrote: @Pckts He was speaking about Southeast Asia " Indonesia, Thailand, Vietnam, Singapore, Malaysia, MORE" Which I have also read as being larger than their Indian Cousins, but I haven't seen weights to support that but I did find one from Vietnam "Dung said they found three small wounds in the shoulder and belly of the male gaur, which was aged around 10 and weighed 800kg. “The gaur’s body parts were intact.” Park rangers are working with the local police and animal health agency to identify the cause of death. On February 28 rangers had found the head and skeleton of a female gaur weighing around 200 kg, also in Ma Da Forest." http://www.thanhniennews.com/society/another-endangered-gaur-found-dead-in-protected-southern-vietnam-forest-60199.html In regards to Southern Indian Gaur being larger than Central, I'm not so sure about that. From my experience it is the terrain that determines the size, Places like Kanha with year round green foliage, large watering holes and lower temperatures will generate healthier specimens. If we look at these forest types for instance  *This image is copyright of its original author I would guess that the Tropical Moist forests would contribute to larger herbivores, having been to Thailand, it certainly has areas that are extremely dense with green plant life and it definitely is wet, so I would assume that quite a few places around that area would have large herbivores as well. But there must be a common ground, if the foliage is too dense than it would be hard for a large herbivore to move. 
I have found few reports regarding the weights of southeast asian gaur.it doesn't concludes all southeasian gaurs are massive by looking only at these news reports.but one can believe the gaurs from these regions on an average bigger than their indian counterparts.by examining their most prefered habitat(semi evergreen to moist decidous)which is abundunt their range.
2 of the weight records i found:
The abundance of such suitable habitat might produced the bigger and more diverse wildlife. In regards to Southern Indian Gaur being larger than Central, I'm pretty sure about that,from the kind of habiat that found in south india. these are my opinions only.it may not be true at all (09-15-2018, 12:40 AM)Suhail Wrote: I have found few reports regarding the weights of southeast asian gaur.it doesn't concludes all southeasian gaurs are massive by looking only at these news reports.but one can believe the gaurs from these regions on an average bigger than their indian counterparts.by examining their most prefered habitat(semi evergreen to moist decidous)which is abundunt their range. Valid opinion, if those Gaur were actually weighed then those are massive individuals, I would have serious doubts that I ever saw a Gaur that was close to 2800lbs in the reserves I went to in C. India.

Almost all bovines are killed with bite to the neck region. Bite to the top portion of neck seems to be the most effective in this killing the prey in a few minutes. I am unable to figure out how it is so effective, does it break the wall of blood vessels or breaks the bone or vertebrae like in case of jaguar? If the second one is right, then bite force of tiger will be somewhere around or more than jaguars'. After the probability of breaking vertebrae, spinal cord is the next most sensitive target. Could this be the reason? Or a bite to the chief nerves or blood vessels eases the way? Does anyone know what is the answer?

Could this be the reason? Or a bite to the chief nerves or blood vessels eases the way? Does anyone know what is the answer? Normally a bovine is killed by biting the top of the neck and severing the spinal cord or biting the bottom or side of the neck to suffocate the animal or to severe the carotid artery. With a throat hold the Windpipe is either crushed or blocked mostly. The trachea, colloquially called the windpipe, is a cartilaginous tube that connects the pharynx and larynx to the lungs, allowing the passage of air and so is present in almost all land animals.
@Jeffrey Then the tiger is able to break the vertebrae of the bovines to be able to reach spinal cord if the bite is at top of their neck. The bite force of tiger is surely much more than the studies present. Jaguar too breaks the bone of cranium of caiman and other prey. The bite force of tiger as per my estimate is slightly higher than jaguar but not on pound for pound basis.

It depending on the neck bite and how large the bovine is the larger the more "difficult" it get. Pound for pound the sumatran tiger could maybe rival the jaguar's bite force.

Rajarshi Banerji ADULT RHINO KILL BY TIGER Tigers in Kaziranga often feed on rhino calves, but direct attacks on adult rhinos is not common. In this image, a male tiger killed an adult rhino that was foraging in a shallow water body by jumping on its back from the higher bank and by breaking its neck. It then intermittently fed on its very rare and huge kill. Location: Kaziranga National Park, Assam  *This image is copyright of its original author Convo that followed: Sudharsan Sathyam Superb capture! May be it's feeding on a dead rhino! Coz it's highly impossible to penetrate it's skin Deep Shubhra Biswas Sudharsan Sathyam Tigers are known to attack and hunt down adult rhinos at Dudhwa... So it's not that impossible Del Hanson Amazing record shot!!! Which zone is this? Rajarshi Banerji Del Hanson Thank you. I don't disclose location of wildlife. Vishal Shah Already dead, there has not been a tiger taking down a grown Rhino this far. It is hard to trust this claim without video. Rajarshi Banerji You would be amazed if you interact with the field staff of the various beats of Kaziranga Core Area :) :) Siddharth SinghSiddharth At Dudhwa a Male called Rhino Hitter has taken down more than 5 Rhinos so far .. Deep Shubhra Biswas Vishal ShahTigers are known to hunt down adult rhinos at Dudhwa for long... And those claims at Dudhwa were properly investigated and then claimed tiger kills... So this one is nothing new... Siddharth Singh Deep Shubhra Biswas yes it was camera trapped by Ganesh Bhatt sir .. 5 Tigers on a carcass.. always between Nov to Feb .. and it was a Male and Female working together Ryan Lunney Did you see the Tiger make the kill? Siddharth SinghSiddharth and 77 others are consistently creating meaningful discussions with their posts. Ryan Lunney I have seen the stalking.. it's like a game .. once the Tiger learns to kill .. nothing can stop them .. in Dudhwa they damaged the hind legs of the Rhino and started eating it while it was alive .. Blood Pressure is a major tool the Tiger uses.. of the Rhino and the elephants Rajarshi Banerji Ryan Lunney I have over 100 shots of this sequence. And another 200+ of the feeding, which was later shared by a monitor lizard, an Adjutant Stork and Crows. :)Can't share any more information right now. Siddharth Singh Brilliant shots! I have one of a tiger stalking the rhino in the dark. (Spotlit by the park staff and photo not of a very good quality) |
