Giant panda Bei Bei celebrated his third birthday Aug. 22 with a special ice cake.

Bei Bei turned 3 years old today! In celebration of his big day, Bei Bei enjoyed an ice-cake, participated in an enrichment painting session and received a new panda-friendly enrichment toy.

A team of reproductive scientists, veterinarians and animal keepers at the Smithsonian’s National Zoo and Conservation Biology Institute have determined that giant panda Mei Xiang (may-SHONG) will not give birth this year.

The exhibits team built the hammocks from sturdy firehose and installed them. There has been a hammock in Bei Bei’s enclosure for several years, but it was starting to show some wear-and-tear as it’s been a favorite resting spot for him and Bao Bao when she lived there.

Beginning today, June 24, the David M. Rubenstein Family Giant Panda Habitat will be closed to keep a quiet area around female giant panda Mei Xiang’s den.

The panda team has started seeing more pronounced behavioral changes in Mei Xiang, which is normal and expected for a pregnant or pseudopregnant giant panda. Overall, she is spending more time sleeping and is less responsive to the keepers.

It’s been almost three months since Mei Xiang was artificially inseminated. Keepers, veterinarians and Smithsonian Conservation Biology Institute scientists have been monitoring her carefully ever since.

The beginning of March was a whirlwind at the Giant Panda Habitat. Mei Xiang finally went into peak estrus March 1 after the panda team had been monitoring her and Tian Tian 24-hours-a-day for nearly a week. There is always a lot of activity around the panda house when Mei Xiang is approaching peak...

A team of reproductive scientists, veterinarians and panda keepers at the Smithsonian’s National Zoo and Conservation Biology Institute performed an artificial insemination on giant panda Mei Xiang.

Keepers have noticed some dramatic changes in Mei Xiang and Tian Tian’s behavior during the past several days. On Saturday, Feb. 17, Mei Xiang started showing behavioral changes that indicate she may be going into estrus within the next few weeks.

As the days get shorter and the weather gets cooler, the pandas are spending more time in their yards. Panda keepers sometimes get asked by the visitors why we place the bamboo and enrichment items in the places that we do when we set up the yards.

Bei Bei started showing signs of abdominal discomfort overnight Saturday, Nov. 25. As a result, the panda team began monitoring him closely. He passed a mucous stool on Sunday, Nov. 26, and began eating and defecating normally again. As of Wednesday, Nov. 29, Bei Bei is bright, alert and fully...

Tian Tian had a preventative health exam yesterday. He was taken to the veterinary hospital, which allowed our veterinarians to get an up-close and in-depth look at him while he was under anesthesia.

The giant panda team at the Smithsonian’s National Zoo and Conservation Biology Institute has determined that Mei Xiang (may-SHONG) will not give birth this year.

The panda team is still waiting to find out if Mei Xiang will give birth or if she is experiencing a pseudopregnancy. Giant pandas’ hormones and behavior mimic a pregnancy even if they are experiencing a pseudopregnancy.

The panda house is closed to the public beginning today, Sept. 1 to provide quiet for Mei Xiang as she enters the final stages of a pregnancy or pseudopregnancy.

Mei Xiang has started exhibiting more behaviors consistent with the secondary hormone phase of a pregnancy or a pseudopregnancy. That means that she has been spending the majority of her time sleeping. Simultaneously, she is starting to build a nest in her den and to eat less. Keepers have also seen...

Beginning Aug. 18, the David M. Rubenstein Family Giant Panda Habitat will be partially closed to keep a quiet area around panda Mei Xiang’s den. Although we are not able to confirm if she is pregnant, Mei Xiang is exhibiting expected, normal behaviors following a secondary hormone rise that are in...

The Giant Panda Habitat will be partially closed to keep a quiet area around female giant panda Mei Xiang’s den. Although keepers are not able to confirm if she is pregnant, Mei Xiang is exhibiting expected, normal behaviors after the secondary hormone rise that are in line with both a pregnancy and...

Veterinarians are giving Mei Xiang weekly ultrasounds to track changes in her uterus. Though it's too early to see a possible cub on an ultrasound, SCBI scientists detected a rise in hormones, indicating Mei Xiang will either give birth or experience the end of a pseudopregnancy in 30 to 50 days.

Behavior can tell the giant panda team quite a bit about the pandas, but the behaviors they exhibit are only half the story. When it comes to predicting when Mei Xiang will give birth, or when she is in the final stages of a pseudopregnancy, scientists rely on a few different factors. They monitor...

Activity at the giant panda habitat has slowed since the flurry of breeding season in May. Keepers, Smithsonian Conservation Biology Institute scientists and veterinarians were monitoring Mei Xiang very closely to determine when she would ovulate. Her chance to conceive a cub arrived May 25. Now...
