They took note of their foraging and mating habits and analyzed samples of their food and feces. The pandas would move from the valleys into the Qinling Mountains and would only return to the valleys in autumn. During the summer months bamboo shoots rich in protein are only available at higher altitudes which causes low calcium rates in the pandas and during breeding season the pandas would trek back down to eat bamboo leaves rich in calcium.
Social encounters occur primarily during the brief breeding season in which pandas in proximity to one another will gather. Due to their sheer size, pandas do not need to fear predators like other herbivores. They can therefore be active at any time of the day. For this reason, pandas do not hibernate , which is similar to other subtropical mammals, and will instead move to elevations with warmer temperatures.
The normal reproductive rate is considered to be one young every two years. Giant pandas reach sexual maturity between the ages of four and eight, and may be reproductive until age Copulation time is short, ranging from 30 seconds to five minutes, but the male may mount her repeatedly to ensure successful fertilisation. The gestation period ranges from 95 to days. The mother will select the stronger of the cubs, and the weaker cub will die due to starvation. The mother is thought to be unable to produce enough milk for two cubs since she does not store fat.
For three to four hours, the mother may leave the den to feed, which leaves the cub defenseless. One to two weeks after birth, the cub's skin turns grey where its hair will eventually become black. Slight pink colour may appear on cub's fur, as a result of a chemical reaction between the fur and its mother's saliva. A month after birth, the colour pattern of the cub's fur is fully developed. Its fur is very soft and coarsens with age. The cub begins to crawl at 75 to 80 days;  mothers play with their cubs by rolling and wrestling with them.
The cubs can eat small quantities of bamboo after six months,  though mother's milk remains the primary food source for most of the first year. The interval between births in the wild is generally two years. In July , Chinese scientists confirmed the birth of the first cub to be successfully conceived through artificial insemination using frozen sperm.
This has resulted in panda fetuses, but no live births. The grandson of Emperor Taizong of Tang is said to have given Japan two pandas and a sheet of panda skin as a sign of goodwill.
Unlike many other animals in Ancient China , pandas were rarely thought to have medical uses. The few known uses include the Sichuan tribal peoples' use of panda urine to melt accidentally swallowed needles, and the use of panda pelts to control menses as described in the Qin Dynasty encyclopedia Erya.

This practice has been termed "panda diplomacy". Their thick hair keeps them warm in the cool, wet mountain zones.
When on all fours, giant pandas average between cm ft. They can weigh between kg lb. One of the interesting evolutionary traits of the panda is their protruding wrist bone that acts like a thumb. This helps the pandas hold bamboo while they munch on it with their strong molar teeth. Bamboo makes up nearly the entire diet of the panda. Due to the low nutritional value of bamboo, pandas need to eat kg lb. Occasionally pandas will eat other available food, including small rodents, eggs, fish and other flora.
Bamboo provides a good amount of water, but pandas need to supplement this with fresh water daily. When pandas are between years of age, they reach maturity and can reproduce. However, female pandas are only able to become pregnant for days each spring!
In this small window of time, male and female pandas find each other through scents and calls similar to that of goats or sheep. They do not roar like other bears. Between 95 and days of becoming pregnant, the female panda will give birth. The newborn cub is blind, hairless, and tiny, weighing only g oz. Completely helpless, the cub cannot move much on its own for nearly 3 months.But plenty of genetic studies have made it clear that pandas are a type of bear, according to the San Diego Zoo. However, in giant pandas, it is S-shaped and directed backward, according to the Animal Diversity Web. During the Cultural Revolution , all studies and conservation activities on the pandas were stopped. Due to the low nutritional value of bamboo, pandas need to eat kg lb. FOOD The panda eats food for about 10 to 12 hours a day about 40 to 80 pounds. Social encounters occur primarily during the brief breeding season 70 - 80 centimeters tall at the about, 4 to 5 feet 1.

Females give birth to one or two cubs although the second cub usually doesn't survive that only weigh 3 to 5 ounces 85 to grams and are about the size of a stick of butter, according to the San Diego Zoo. Panda cubs don't open their eyes until they are six to eight weeks old and they weigh between three to five ounces.
Back to Animals What is a giant panda? Poaching is not that big a problem but sometimes pandas get caught in traps made for other animals. In , Ruth Harkness became the first Westerner to bring back a live giant panda, a cub named Su Lin  which went to live at the Brookfield Zoo in Chicago. How long do they live? In captivity, zoos typically maintain the giant panda's bamboo diet, though some will provide specially formulated biscuits or other dietary supplements.
