Tiger cub killed by wild dogs in Chanda

A pack of wild dogs reportedly killed a tiger cub in Dhaba range in Gondpipri tehsil in the afternoon. Forests in Chandrapur district have lost in all seven tigers this year now.

The patrolling squad discovered the partially eaten carcass of the tiger cub in compartment no. 561, near village Vejgaon in Dhaba range under Central Chanda forest division, during routine patrolling in the afternoon. It appears that a pack of wild dogs brought down the tiger cub and eat the rear portion of its body.


"Forest watchers recruited for patrolling saw the pack of wild dogs eating the carcass. The dogs fled when the watchers approached the dead body. They also discovered a large number of wild dog pug marks in the area," said ACF Pradeep Kottewar.

Sources claimed that the cub is aged around eight months and measured around 80cm in length. Sex of the cub however could not be learnt as its genitals had been eaten by the dogs. Forest officers have ruled out poaching, claiming that its body parts like teeth and nails are intact, while skin has been damaged as carcass was eaten by wild dogs. The dead body of the cub was fresh and forest officials suspect that the cub was killed not long before it was detected by the patrolling squad.

DCF, Central Chanda division, Madan Kulkarni and his subordinates rushed to the spot on getting information. Veterinary doctor PM Kadukar was summoned for post mortem at the spot. Wildlife activist Bandu Dhotre was present as representative of PCCF and honorary wildlife warden of Gadchiroli Mahendra Singh Chavan was summoned as representative of NTCA to witness the post mortem.

So far six tigers, one each in every month, have died in Chandrapur district this year. First tiger was poached through electrocution in Jharan range of FDCM and its partially decomposed carcass sans all four paws was discovered on January 23. Second tiger was found dead in suspicious condition in Lohara teak research centre on February 18. Forest officers claimed it was a hit and run case, but possibility of electrocution was not ruled out. Third tiger was found dead near village Kitadi in Moharli Forest Range (Territorial) on March 1. Its body was decomposed and forest officers termed it as natural death.

Fourth tiger was killed in steel jaw trap laid by poachers in Palasgaon range on April 26, while one more was maimed for life in another trap at the same spot. Fifth tiger was poached and its body sans head and paws and chopped into 11 pieces was thrown near Borda village in Chandrapur range on May 18. This killing of tiger cub allegedly by wild dogs has taken the tiger death toll in Chandrapur to six this year. Last year four tigers had died in the district.

Abstract
Interactions between carnivores during the defence of kills may be one reason why certain carnivores live in groups. This is especially true of lions, hyaenas and the African wild dog. The dhole or the Asiatic wild dog, primarily a pack living animal, has been observed to regularly interact with both tigers and leopards. Such interactions have taken place over kills and otherwise. In this report, five such interactions are described. It was found that the pack's behaviour of surrounding bushes and trees on which the cat was confined precluded immediate escape. The presence of sentinels, while the pack was resting, warned the pack of the presence of a big cat and the pack grouped when a big cat appeared. Costs to both individuals within the dhole packs and the cats involved in the encounters were found to be slight. The reasons for such potentially costly encounters could be competition for finite food resources or thwarting predation. Dholes have a significant diet overlap with both leopards and tigers and aggressively encounter with leopards but not with tigers. Differences between diet overlaps may not be the basis behind the differences in aggression. It is more likely that, the small size of leopards and the fact that they predate more often on dholes, cause dhole packs to be more aggressive to leopards than to tigers. The size of carnivore groups may thus pose an advantage during competitive interactions among carnivore species.

Abstract
Species within a guild vary their use of time, space and resources, thereby enabling sympatry. As intra-guild competition intensifies, such behavioural adaptations may become prominent. We assessed mechanisms of facilitating sympatry among dhole (Cuon alpinus), leopard (Panthera pardus) and tiger (Panthera tigris) in tropical forests of India using camera-trap surveys. We examined population-level temporal, spatial and spatio-temporal segregation among them across four reserves representing a gradient of carnivore and prey densities. Temporal and spatial overlaps were higher at lower prey densities. Combined spatio-temporal overlap was minimal, possibly due to chance. We found fine-scale avoidance behaviours at one high-density reserve. Our results suggest that: (i) patterns of spatial, temporal and spatio-temporal segregation in sympatric carnivores do not necessarily mirror each other; (ii) carnivores are likely to adopt temporal, spatial, and spatio-temporal segregation as alternative mechanisms to facilitate sympatry; and (iii) carnivores show adaptability across a gradient of resource availability, a driver of inter-species competition. We discuss behavioural mechanisms that permit carnivores to co-occupy rather than dominate functional niches, and adaptations to varying intensities of competition that are likely to shape structure and dynamics of carnivore guilds.


In addition to the behavioural adaptations that we studied, antagonistic interactions among these species have been reported; tigers and leopards kill and prey on dholes [6,18], dholes, leopards and tigers steal kills from each other, and leopards can escape from tigers and dholes by climbing trees but are sometimes killed [18,20]. Such rare antagonistic interactions studied using radio-telemetry may reveal complex interplay of behaviour and ecology among these predators.

No mention of Dholes killing Tigers.





"Comment (French version below) / A few dholes were playing together. It was a family including two adults and five juveniles. Then, one of the two adults raised the head and rushed in the bush. It was then joined by others and we heard groans during a few minutes. We saw nothing because of the very dense vegetation. We thought that they were bickering or playing between them. One of the dholes went out on the other hand hastily of the bush and ran away far off. Then we saw the tiger going out of the bush in front of us and we understood that it had killed one of the two adults. The second dhole adult continued to follow the tiger as it can be seen below where I grouped two photos taken successively."
