Giant Panda Habitat
SINZPV_190607_037.JPG: Didn't I Just See a Panda?
You passed several animals from Asia on your way here. You may have seen sloth bears, clouded leopards, Asian small-clawed otters, and fishing cats. You also passed red pandas. But even though red pandas and giant pandas are both "pandas," they aren't at all closely related.

SINZPV_190607_042.JPG: What is a Panda?
Language experts think "panda" comes from the Nepalese nigalya ponya, which translates to "bamboo footed" or "bamboo eater." Red pandas and giant pandas share a diet, habitat, and name, and they both have pseudo-thumbs for grasping bamboo. But red pandas and giant pandas are in different families.
Red pandas are distantly related to raccoons. Giant pandas are bears.

SINZPV_190607_130.JPG: Timeline
First Pandas in America
Giant pandas appeared in American museum collections as early as 1919. But the public had never seen a live panda until 1936 when traveler Ruth Harkness arrived home with a cub taken from the wild. In 1937 she sold the cub, named Su-Lin, to Chicago's Brookfield Zoo, where it was visited by enormous crowds.
1930s-1950s
Zoos begin to display giant pandas.
The arrival of Su-Lin sparked American interest and the Brookfield, Bronx, and Saint Louis zoos all acquired pandas for exhibit. By the 1950s, however, these animals had passed away. Due to changing Chinese policies, American zoos could not acquire new pandas.

SINZPV_190607_137.JPG: 1970s
Panda Diplomacy
China and the United States began a new diplomatic era. In a goodwill exchange the U.S. sent two musk oxen to China, which send two giant pandas in return. Ling-Ling and Hsing-Hsing arrived at the National Zoo on April 16, 1972. They were the first pandas in the U.S. in nearly 20 years.
SINZPV_190607_141.JPG: Trying for Cubs
Early breeding attempts by Ling-Ling and Hsing-Hsing were unsuccessful, so in 1982 the Zoo tried to artificially inseminate Ling-Ling. Although this did not result in a pregnancy, our scientists gained important panda breeding knowledge.
SINZPV_190607_144.JPG: 1980s
Learning about Breeding
In March 1983, Ling-Ling and Hsing-Hsing mated successfully. Ling-Ling gave birth to a cub in July, but it died within a few hours. Over the next decade, although Ling-Ling had four more cubs, none survived. Zoo scientists worked hard to learn as much as they could about panda reproduction and health.
SINZPV_190607_149.JPG: We bid farewell to our first pandas.
The Zoo's beloved first panda pair lived here for many years. Staff gained valuable knowledge from working with and observing them. In 1992, Ling-Ling died. Seven years later Hsing-Hsing passed away. They left behind a critical scientific legacy and countless panda fans.
SINZPV_190607_151.JPG: We share our knowledge.
In 1987, Zoo scientists began teaching wildlife conservation and management courses in China. To this day, we train scientists, conservationists, wildlife managers, and educators. This partnership has grown over the years to include mentorships, fellowships, work exchanges, and conferences.
SINZPV_190607_153.JPG: Panda cubs make the news.
San Diego Zoo made history in 1999 when panda Bai Yun gave birth to the first surviving cub at an American zoo. Zoo Atlanta welcomed the first set of surviving panda twins in the U.S. in 2013.
SINZPV_190607_156.JPG: 1990s
Zoo staff organized the first international giant panda conference in 1991. Since then, we have partnered with Chinese scientists to create health and breeding plans for pandas in human care. We have led training courses for Chinese veterinarians and worked with wildlife biologists in giant panda reserves.
SINZPV_190607_160.JPG: Our First Cub
In 2000, Mei Xiang and Tian Tian arrived and our staff eagerly awaited the time when they could breed. In 2005, Mei Xiang gave birth to a healthy male -- our first surviving cub. He was named Tai Shan, which means "Peaceful Mountain."
SINZPV_190607_161.JPG: Rare Opportunities
The breeding season is only a very short window of time when Mei Xiang can get pregnant. If Mei Xiang and Tian Tian show interest in mating, they are given the opportunity. Their attempts to breed naturally, however, have not been successful.
SINZPV_190607_164.JPG: Mei Xiang experiences pseudo-pregnancies.
During breeding seasons, female pandas display certain behaviors that could indicate a pregnancy. These same behaviors are seen even in a false pregnancy, which is common in giant pandas. Mei Xiang had several pseudo-pregancies between 2005 and 2013.
SINZPV_190607_167.JPG: More Cubs for Mei Xiang
In 2013 and 2015, Mei delivered twins. With pandas, a smaller twin often does not survive. Even with intensive care by Zoo staff, only the larger, healthier cubs thrived. Bao Bao and her younger brother Bei Bei both have names that mean "Precious Treasure."
SINZPV_190607_170.JPG: Making a Difference
Panda lovers and conservationists worldwide rejoiced when the conservation status of giant pandas improved from "endangered" to "vulnerable" in 2016. Decades of hard word resulted in an increased number of pandas in the wild.
SINZPV_190607_176.JPG: Giant Pandas are Bears
SINZPV_190607_181.JPG: Panda Post:
Why are Pandas Black and White?
No one really knows, but researchers have a few ideas. Their coloring is good camouflage in the sunlight and shadow of the forest. Unique "eye masks" may help pandas recognize each other, while the black ears could signal aggression or ferocity to other animals.

SINZPV_190607_186.JPG: Newborn
A newborn panda is blind, weak, and tiny. It depends on its mother for warmth and milk. Newborn cubs squeal very loudly when they are hungry or uncomfortable.
SINZPV_190607_189.JPG: Three Months
At three months, panda cubs open their eyes and prepare to take their first steps. Their teeth start to come in, but they are still nursing and not yet eating bamboo. They can make other sounds now.
SINZPV_190607_192.JPG: One Year
Cubs are eating bamboo and may weigh as much as 75 pounds. Young pandas use different sounds to get attention or indicate distress.
SINZPV_190607_195.JPG: Fully Grown
Adult pandas can bleat, honk, chirp, roar, or squeal to communicate. Some sounds indicate an interest in mating, while others might be warnings to retreat. How many different calls do you hear?

Giant pandas, especially cubs, seem extremely playful.
