Panda
This peaceful creature with a distinctive black and white пальто is adored by the world and considered a national treasure in China. The медведь also has a special significance for WWF. The panda has been WWF's logo since our founding in 1961.

The rarest member of the медведь family, Панды live mainly in bamboo forests high in the mountains of western China, where they subsist almost entirely on bamboo. They must eat from 26 to 84 pounds of it every day, a formidable task for which they use their enlarged wrist Кости that function as opposable thumbs.

Newborn Панды are about the size of a stick of butter—about 1/900th the size of its mother—but can grow to up to 330 pounds as adults. These bears are excellent tree-climbers despite their bulk.

Tiger
The largest of all the Asian big cats, Тигры rely primarily on sight and sound rather than smell. They typically hunt alone and stalk prey. A tiger can consume up to 88 pounds of meat at one time. On average, Тигры give birth to 2-3 cubs every 2-2.5 years. If all the cubs in one litter die, a секунда litter may be produced within 5 months.

Тигры generally gain independence at two years of age and attain sexual maturity at 3-4 years for females and at 4-5 years for males. Juvenile mortality is high however—about half of all cubs do not survive еще than two years. Тигры have been known to reach the age of 26 years in the wild.

Males of the largest subspecies, the Amur (Siberian) tiger, may weigh up to 660 pounds. For males of the smallest subspecies—the Sumatran tiger—upper range is at around 310 pounds. Within each subspecies, males are heavier than females. Тигры are mostly solitary, apart from associations between mother and offspring. Individual Тигры have a large territory and the size is determined mostly by the availability of prey. Although individuals do not patrol their territories, they visit over a period of days или weeks and mark their territory with urine and feces.

Across their range, Тигры face unrelenting pressure from poaching, retaliatory killings and habitat loss. They are forced to compete for Космос with dense and often growing human populations.
