This is the first time a Zoo in the United States has experienced a successful giant panda pregnancy and birth via artificial insemination using only frozen semen. Mei Xiang keeps her cub tucked under her arm, or under her chin much of the time. Panda cubs are unable to regulate their own body temperature, so Mei Xiang cradles the cub closely to her body to keep him or her warm.
She moves the cub by picking it up in her mouth. The cub squeals when it wants to nurse or be repositioned. Regular loud squeals are signs of a healthy cub. Sometimes it appears as though Mei Xiang is breathing heavily.
She is breathing on her cub to keep the cub in a warm and humid environment. Male pandas are not involved in the care of their cubs. Fathers and cubs may never encounter each other in the wild. No, in the wild giant pandas are solitary and separate from their mothers around the age of 18 months. Keepers strive to mimic those conditions at the Zoo. The panda team prepares for a panda cub birth based on behaviors they see, hormones they monitor and ultrasounds.
Smithsonian Conservation Biology Institute scientists look for a rise in Mei Xiang's urinary progesterone. A rise indicates that she would give birth to a cub or experience the end of a pseudopregnancy in days. The panda team then begins monitoring Mei Xiang 24 hours a day and attempts ultrasounds. When the panda team conducts a health check they have a list of things to accomplish. They will measure the cub's body weight, assess hydration, take a body measurement, check the oral cavity, check the umbilicus, check the genitalia and rectal area, palpate the abdominal cavity, take a fecal culture, take the rectal temperature, listen for a heartbeat and lung sounds, and collect any urine produced.
Mei Xiang's den was rearranged in to allow the panda team to get closer to her and a cub for health checks, or to retrieve the cub. There is a barrier in the den, which keeps members of the panda team safe when they enter the den with Mei Xiang and a cub. Mei Xiang and the keepers are never on the same side of the barrier. When the panda team removes a cub from the den for a health check, a minimum of two keepers are always present.
No more than three keepers enter the den at the same time. One keeper focuses on retrieving the cub, and another keeper monitors Mei Xiang. Keepers offer Mei Xiang bamboo, juice, sugarcane or honey water while they retrieve the cub during the first weeks of his life. When Mei Xiang begins leaving the cub more frequently for longer periods of time, keepers can retrieve the cub from the den while Mei Xiang is eating in the adjacent enclosure. Yes, Mei Xiang gave birth to two cubs Aug.
The first was born at p. Developed from the experience and success of Chinese partners and other zoos, the hand-rearing protocol provided the panda team with several strategies to manage twin cubs.
Swapping the cubs between mother and hand-rearing is a proven method that enables Zoo staff to best care for twins in the event that the mother cannot manage two cubs, which was the case with Mei Xiang. When swapping the cubs became difficult, the panda team had in their possession the smaller cub, which was losing weight, needed calories and energy, and was at risk if he remained away from Mei Xiang for a prolonged period of time.
The cub's best option for survival was to receive supplemental feedings via bottle and tube, but both techniques present risks. The team witnessed some regurgitation of food during one feeding, so the cub was started on antibiotics as a preventative measure. The smaller cub was with Mei Xiang from about 2 p.
When the panda team swapped the cubs, they assessed the cub and had concerns, because he had not increased in weight, appeared weaker and exhibited possible respiratory issues.
He died shortly after 2 p. Based on the necropsy's gross findings, Zoo pathologists and veterinarians determined the most likely cause of death to be complications associated with aspiration of food material into the cub's respiratory system resulting in the development of pneumonia. Mei Xiang cared for whichever cub was in the den with her. But female giant pandas struggle to care for more than one cub at once. That is why the panda team was swapping cubs, so Mei Xiang could take care of one at a time.
Several people who watch the panda cam have mentioned seeing a mouse that occasionally runs through Mei Xiang's den. The Giant Panda building is a secure, dry area protected from the elements, so it is inherently attractive to all sorts of opportunistic rodents.
The food that the giant pandas eat also attracts mice. The Zoo has a team of pest management specialists who work with keepers to reduce and control the visiting rodent population throughout the Zoo.
And although keepers diligently work to exclude them, rodents are amazingly smart animals something you can learn more about at the Zoo's Think Tank exhibit. The pest management team has even observed rodents outsmarting traps by flinging them against walls, and then making off with the bait. In addition, the Zop refuses to use pesticides in its panda exhibit, which makes the challenge of controlling the rodent population a little more difficult.
Of course, much as the Zoo's team admires rodents' cognitive abilities, they would still prefer them not to be in with the animals. Fortunately, Mei Xiang is a pound bear with strong instincts to protect her cub. No mouse --however clever or cunning-- poses a serious threat to her or her cub. Donate now. Skip to main content. Entry passes are required for all guests, including infants.
All visitors ages 2 and older are required to wear a mask in all indoor spaces at the Zoo, regardless of their vaccination status. Fully vaccinated visitors do not need to wear a mask in outdoor areas. Share this page:. Today, pandas have fewer predators than they did historically. Tigers are generally not found in what remains of panda habitat, and leopards are found in reduced numbers. But the drive to remain safe is still the same, and is seen even in pandas cared for in zoos and breeding centers.
The San Diego Zoo has had a love affair with giant pandas ever since two of the black-and-white bears came to visit in for days. After years of red tape and tons of application paperwork, the Zoo and China agreed on a year research loan of two giant pandas, Bai Yun and Shi Shi, who arrived at the Zoo in A brand-new habitat was built for our panda guests—and was later expanded and renovated—called the Giant Panda Research Station.
In , our panda loan was extended for another five years and was renewed in The panda loan agreement concluded in , and giant pandas Bai Yun and Xiao Liwu were repatriated to China in spring , in keeping with the terms of our agreement.
All six of the pandas born at our zoo have returned to their homeland in China, where they continue to make us proud! Giant pandas face big problems: Today, only over 1, giant pandas survive on Earth. They are currently listed as Vulnerable, thanks to numerous conservation efforts that have helped to increase their population. However they, still face many serious threats:.
The country has more than a billion people. Just as in the US, with more people have come more roads, homes, cities, and farms. They mine, harvest trees, and use other natural resources. In fact, panda-suitable habitat decreased by half between and Populations of pandas have become small and isolated, hemmed in by cultivation. In some pockets, very few pandas are found. They are isolated and cut off from other sources of bamboo—and from other pandas.
In some areas, forest clear-cutting has completely removed all large trees—and all appropriate tree and rock den sites. Without a protective den, panda cubs are more susceptible to cold, disease, and predators. Low reproductive rate: Pandas like to be by themselves most of the year, and they have a very short breeding season, when a male looks for a female to mate with. Females give birth to one or two cubs, which are very dependent on their mother during the first few years of life.
Mother pandas care for only one of the young. In panda facilities in China, wildlife care specialists help to hand raise any twin cubs; one baby is left with the mother and the wildlife care specialists switch the twins every few days so each one gets care and milk directly from the mother. Bamboo shortages: When bamboo plants reach maturity, they flower and produce seeds before the mature plant dies.
The seeds grow slowly into plants large enough for pandas to eat. Giant pandas can eat 25 different types of bamboo, but they usually eat only the 4 or 5 kinds that grow in their home range.
The unusual thing about bamboo is that all of the plants of one type growing in an area bloom and die at the same time. When those plants die, pandas must move to another area. This is why good panda habitat should have several different varieties of bamboo. Hunting: When hunters set snares for other wildlife, like musk deer, the traps can kill pandas instead.
Protecting pandas: Panda protection efforts in China began back in , and in , the Chinese Ministry of Forestry and the World Wildlife Fund formulated a management plan for the giant panda and its habitat. It called for reducing human activities in panda habitat, managing bamboo habitat, extending the panda reserve system, and maintaining populations of pandas in human care. China has set up 65 panda reserves that protect panda habitats from further development.
Some are off limits to people completely, while others are shared-use areas like our national forests. Natural corridors connect some reserves to help keep panda populations together. Today, China is currently gaining forestland. It takes an international effort: Back in the s, biologists didn't know if they could save pandas from extinction. Little was known of their behavior, and pandas did not reproduce well in zoos. Then, San Diego Zoo Wildlife Alliance partnered with Chinese colleagues at panda preserves to create a conservation strategy.
We developed early-detection pregnancy tests, as well as a milk formula for panda cubs that raised survival rates from zero to percent. We also began using GPS technology to track pandas and learn how far they range.
In , we reached the milestone number of pandas in zoos worldwide and breeding centers in China, which scientists believe will ensure a self-sustaining population. We are definitely boosting panda survival rates! There is still much that we don't know about pandas. By gathering more than 20 years' worth of data at the San Diego Zoo, where the pandas were easy to observe, we gained a better understanding of what they needed to thrive in their natural habitat.
Working together with Chinese panda experts may help increase the number of giant pandas and ensure the future survival of the giant panda population. A giant panda milk formula created by the Zoo's nutritionist, and a hand-rearing technique developed by the Chinese called "twin swapping," have transformed the survival rate of nursery-reared panda cubs in China from 0 to 95 percent. The giant panda breeding rate at the Wolong Breeding Center in China increased dramatically following multiyear collaborations with the San Diego Zoo.
Work by our scientists has advanced pregnancy diagnosis, and the population of pandas in human care has reached the milestone of bears, the minimum necessary to sustain genetic diversity for the next years.
What YOU can do to help pandas: People ask us every day how they can help save pandas. You can make a big impact by making some simple changes in your daily lifestyle, like knowing where the products you purchase come from, choosing accordingly, and buying fewer things or items with minimal packaging.
FSC-certified forest products are from responsibly harvested and verified sources. Look for the FSC certification on bamboo products, too. By supporting San Diego Zoo Wildlife Alliance, you are our ally in saving and protecting wildlife worldwide.
Gestation: Average "pregnancy" is about days, and documented range among zoo pandas is to days; however, true gestation of the fetus only takes about 50 days.
Weight: Females, to pounds 70 to kilograms ; males, to pounds 86 to kilograms. Pandas poop a lot—as much as 50 times a day. Giant pandas have unusually thick and heavy bones for their size, but they are also very flexible and like to do somersaults.
In zoos, they like to play with enrichment items like piles of ice or sawdust, puzzles made of bamboo with food inside, and different scents like spices. Sometimes a female can be pregnant with two cubs but only give birth to one—her body reabsorbs the other embryo. At only 3 to 5 ounces 85 to grams , a newborn panda is about times smaller than its mother. In contrast, an average human baby is about 18 times smaller than its mother.
The pandas simply peel off the hard outer bark with their teeth to get to the juicy part. Main menu. Search form Search. Ailuropoda melanoleuca. Sounds bonk. Panda cub.
