Tigers are the largest species of big cat in Asia. Relying primarily on sight and sound rather than smell, they are solitary hunters who tend to stalk their prey at night. Large ungulates---hoofed mammals such as wild boar, deer, elk, and water buffalo---make up the majority of their diet and a tiger can consume up to 88 pounds of meat at one time. On average, tigers give birth to two or three cubs every two years. If all the cubs in one litter die, a second litter can be produced in as little as five months. Tigers face unrelenting pressures from poaching and habitat loss and are forced to compete for space with dense and often growing human populations. More money has been spent on tiger conservation than on preserving any other species in the world, yet wildlife biologists have been seemingly unable to stop the decline of the iconic big cat in the face of poaching and habitat loss. Researchers now use "camera traps"—cameras linked to a triggering mechanism—to estimate tiger populations. This is effective for counting tigers because every tiger has a unique pattern of stripes, which allows individuals to be identified. #tiger #amnh #biodiversity #bigcat #tigers #tigers #tigercub #feline #predator #naturalhistory #tiger? #tigercubs
