Tigers Hunting A Bird

Tigers may kill such formidable predators as leopards, pythons and even crocodiles on occasion, although predators typically avoid one another. When seized by a crocodile, a tiger will strike at the reptile's eyes with its paws. Eighteenth century Physician Oliver Goldsmith described the frequent conflicts between mugger crocodiles and tigers that occurred during that time. When the tigers impelled by thirst, frequently descended to the rivers to drink and, on these occasions tigers were seized and killed by the muggers, though more often the tiger escaped and the reptile was disabled. Leopards dodge competition from tigers by hunting in different times of the day and hunting different prey. With relatively abundant prey, tigers and leopards were seen to successfully coexist without competitive exclusion or inter-species dominance hierarchies that may be more common to the savanna. Tigers have been known to suppress wolf populations in areas where the two species coexist. Dhole packs have been observed to attack and kill tigers in disputes over food, though not usually without heavy losses. Lone golden jackals expelled from their pack have been known to form commensal relationships with tigers. These solitary jackals, known as kol-bahl, will attach themselves to a particular tiger, trailing it at a safe distance in order to feed on the big cat's kills. A kol-bahl will even alert a tiger to a kill with a loud pheal. Tigers have been known to tolerate these jackals: one report describes how a jackal confidently walked in and out between three tigers walking together a few feet away from each other. Siberian tigers and brown bears can be competitors and usually avoid confrontation; however, tigers will kill bear cubs and even some adults on occasion. Bears (Asiatic black bears and brown bears) make up 5–8% of the tiger's diet in the Russian Far East. There are also a few records of brown bears killing tigers, either in self defense or in disputes over kills. Some bears emerging from hibernation will try to steal tigers' kills, although the tiger will sometimes defend its kill. Sloth bears are quite aggressive and will sometimes drive young tigers away from their kills, although it is more common for Bengal tigers to prey on sloth bears.
Conservation efforts
Poaching for fur and destruction of habitat have greatly reduced tiger populations in the wild. At the start of the 20th century, it is estimated there were over 100,000 tigers in the world but the population has dwindled to between 1,500 and 3,500 in the wild. Some estimates suggest that there are less than 2,500 mature breeding individuals, with no subpopulation containing more than 250 mature breeding individuals.
