Pandas in Winter

Cold temperatures? Extra bamboo? Works for Bai Yun!

Cold temperatures? Extra bamboo? Works for Bai Yun!

For the first time in a long time, our pandas are actually getting some truly winter weather. We’ve had some rain recently, and temperatures in the first week of the new year were really low for our region. And the geography of the Zoo means some parts of the grounds feel the chill more than others; Panda Canyon is usually 10 to 15 degrees cooler than the main entrance (where temperatures were in the mid-50s). Although the staff is feeling a bit chilly, the bears are loving this weather!

Giant pandas have a very thick, dense fur coat and like most bears they will try to gain as much weight as possible for winter, but they do not go into torpor (commonly called hibernation). Unlike their counterparts in China and zoos in colder parts of the world, our pandas don’t usually have much of a winter to deal with, but rest assured they are all doing just fine with this cold snap!

We always offer more food than what the bears will actually eat. This allows them to have variety in their diet but also giving them access to extra calories should they so desire. Our pandas do not weigh as much as other pandas that go through more severe winters, because they don’t need the extra insulating fat layer here in San Diego.

As someone who has worked both directly and indirectly (as a Panda Narrator) with the bears, I can honestly say that I love watching them in cold weather. You get to see them eat more and the younger pandas get a little more hop to their step. Yun Zi was one of my favorites to watch in winter. He was always an active fellow, but when it was cold or raining he’d roll in the mud and really tear his exhibit apart. Not always fun to clean up after, but a blast to observe!

No matter what the weather, Bai Yun tends to do her normal thing—eat till she’s tired, then take a nap. I often joke that she’s been here in San Diego for so long nothing much can surprise her anymore. Gao Gao will remain off exhibit in the North Exhibit, with regular access to his bedroom. The perk about having the back area to himself is that he can pretty much run his day however he wants. Inside or out he’s got full reign of the area in the back. Mr. Wu will be on exhibit, and I’m looking forward to watching him and see how he reacts to this cold snap. I know it’s not cold compared to where a lot of you are from, but for these bears, and us, it’s definitely a change!

Happy New Year and hope you are all well! Come see us soon in 2015!

Dealing with Noise in Panda Canyon

Bai Yun is a pro at dealing with activity around Panda Trek.

New noises catch Bai Yun’s attention, then it’s back to “business as usual.”

As many of you have seen on Panda Cam and in person, young Mr. Wu is off exhibit at times and only Bai Yun is present. Rest assured there is nothing wrong with him and he is perfectly fine. Our Zoo is coming up on its 100th birthday soon, so we are improving areas and updating where we can. With that comes a certain amount of noise that we really cannot get away from, so we closely monitor our animals for any signs of stress.

Xiao Liwu, being younger and not as experienced with new sounds, is more likely to react to the construction noise. Bai Yun is typically a pro at changes and has been managing extremely well. One of the benefits of having a panda narrator keeping an eye on the bears is that the narrator is familiar with each animal and can tell the Panda Team when there is a change in behavior. Our Web Team will always do its best to notify you when there may be a change in who is out for viewing, but the fact of the matter is that things can change quickly here, and we often need to make judgment calls quickly, too.

When the bears are off exhibit, they still have an outside yard they can go into if they so choose. Both of the north exhibits are close to bedrooms and, if needed, the keepers can give the pandas access to the bedrooms. The bedrooms offer a dry and cozy area for the pandas. Keepers often fill a giant tub full of hay or shavings for the bears to rest in, and there is a garden room for them to go into as well. Having a building between them and the extra noise often makes a huge difference in a panda’s comfort level and helps diminish any stress behavior.

Bai Yun is an expert at dealing with noise. When we were building the rest of Panda Trek, she was still able to be out in the main viewing area, right next to the noise. There were, of course, days where we noticed that she was a little annoyed with the activity level and so gave her access to her bedroom. There are several cameras in the area, and the panda narrator and guest ambassador all keep an eye—and ear—out for her to make sure that she is comfortable. In many situations, just giving her 10 to 15 minutes in her bedroom to get a little break will often set her right. In addition, we always do our best to make sure that she has extra bamboo that she is fond of and to try and keep her busy with enrichment.

Come see us soon, and please know that we are always thinking of how to make this an easy time for our animals!

Lazy Gao Day

Panda Cam caught Bai Yun enjoying some treats on her "plate."

Panda Cam caught Bai Yun enjoying some treats on her “plate.”

We don’t get to see much of our senior panda, Gao Gao, on Panda Cam. But rest assured he is looking good, eating well, and, in the words of San Diego Zoo keeper Karen Scott, he seems “happy.” Gao is even at his ideal weight: 170 pounds (77.2 kilograms).

So why can’t guests view Gao Gao these days? Well, as Karen explained, Gao Gao and his son, Xiao Liwu, are “like peas in a pod,” personality-wise. “Mr. Wu” doesn’t like the construction noise as we build our new Asian leopard habitat, and neither does his dad! They are much more comfortable farther away from the intermittent noise. Xiao Liwu is currently in the off-exhibit north yard, where he can sometimes be seen on Panda Cam, and Gao Gao has access to another off-exhibit yard. Bai Yun, our matriarch, remains in her normal exhibit, where guests can admire her munching contentedly on bamboo. Nothing fazes this panda mama!

Although Gao Gao can go in his outside yard whenever he wants to, he sometimes prefers to have what Karen calls a “lazy Gao day.” He has a large rubber tub that he uses as a comfy bed. Keepers fill the tub with a flake of excelsior hay, and Gao likes to stretch out in it, resting on his back, his legs straight out and his forelimbs dangling over the edge. The other day, Karen put FOUR flakes of hay in the tub and fluffed up some of it to make a pillow for Gao. Panda heaven! With his pile of bamboo nearby, Karen says all he really needed was a TV to watch a football game or two.

Pandas Keep Cool

It’s been warm in San Diego lately, and some of you may be wondering how our giant pandas are kept comfy. Senior Keeper Kathy Hawk filled me in on the hot-weather protocol used in the San Diego Zoo’s Panda Trek.

There are thermometers in shaded areas of each panda enclosure, and if the temperature reaches 85 degrees Fahrenheit (29.4 degrees Celsius), the pandas are given access to their air-conditioned bedrooms. The panda station has its own ice-making machine, so keepers can fill tubs with ice to make ice beds for some cool lounging, or they can make an ice-cube pile for flopping on (the pandas, not the keepers!). Sometimes food treats are added to the ice to encourage use.

Bai Yun knows how to relax on a warm day!

You may have seen the mist fans in each yard. These fans mix water and air to blow a cooling mist into the enclosure. Kathy said the pandas really seem to enjoy the shrouded mist the fans create. Ice treats or popsicles made with applesauce or other panda delights are offered as both enrichment and as another way to keep cool. And, of course, each enclosure has a pool to soak in.

Xiao Liwu rests after a big meal, the mist fan blowing on his sweet face.

Kathy emphasized that anytime there is high humidity, no matter the actual temperature, the pandas are pulled off exhibit. Keepers are pro-active about avoiding any signs of early heat stress with these precious bears, and all three are closely monitored.

Thank you, panda keepers, for always taking such good care of these black-and-white bears. Your work is much appreciated!

Pandas: Back in Main View

Bai Yun and Xiao Liwu, caught on camera this week

Bai Yun and Xiao Liwu, caught on Panda Cam this week

Pandas are officially back in the main viewing area of Panda Canyon at the San Diego Zoo. I think the cub, Xiao Liwu, is thrilled to have his favorite branch back, and Bai Yun is still trying to fit on that little hammock to take her naps. Yun Zi has plenty to keep him busy with his climbing structures and, of course, scent marking the exhibit. In fact, that was the first thing I noticed them doing when they were put back into the area; Bai Yun spent most of the day marking her territory again, mainly on the ground, and Yun Zi was even getting some handstands in there on the wall.

I’ve had a lot of questions from guests coming into the area about why we needed to close the main viewing exhibit for a while. The primary reason for closing the exhibit was to re-roof the building; after removing the old roof, additional structural repairs were completed. We also had a new cool zone pump installed. Whenever we close the exhibit, we try to get as many projects done as possible!

The first thing I noticed was how cut back many of the branches were, and they were able to cut quite a bit of the bamboo behind and around the exhibits. Cutting the branches is important for everyone’s peace of mind; although the pandas don’t jump from branches, we want to make sure that our perimeter is secure and that each bear stays inside. The bamboo trimming is also important for the health of the bamboo, to provide sunlight and ventilation. Several guests have noted that it is much easier to see the cub when he is at the top of the pine tree now that there aren’t as many branches blocking the view. Also, cutting down bamboo makes it easier for keepers to look into exhibits and possibly work with the bears along the back fence line.

Keepers were also able to put fresh soil and mulch down around the enclosure, and the bears are having a blast in it. Bai Yun and the cub have been rolling in the mulch and playing quite a bit in it. Yun Zi has also been rolling around in it, so much so that guests are asking if the pandas are unusually dirty these days. We always like to see the bears being this active, and I know that our Panda Cam viewers and guests love to have these moments on camera.

Mom and cub have been quite entertaining these days, especially when Bai Yun is trying to eat her lunch. One thing I definitely notice with this cub is how patient she is with him. I actually saw Xiao Liwu take a piece of bamboo that she was eating right out of her mouth and sit in her lap while he ate it. I’ve seen previous cubs TRY this with Bai Yun, and they were usually sent rolling down the hill! Stealing her food was something Bai Yun didn’t normally put up with. This cub, in my book, has gotten away with more than any other cub I’ve seen before.

I hope you all have a wonderful holiday season and keep an eye on the Panda Cam!

Long Time, No See Bears

Bai Yun seems to like the spotlight!

Bai Yun seems to like the spotlight!

Working at the San Diego Zoo for nine years now, I’ve been able to have some amazing experiences and opportunities. One of my most recent was to go on a three-month loan to work on the Elephants Odyssey team taking care of dromedary camels, Baja pronghorn, wild burros, and a very sweet Mustang named Mo. As my loan came to an end, I was sad to leave the animals I had come to love but was curious to see how the pandas were doing, especially our little boy, Xiao Liwu!

On my first day back as a panda narrator, Bai Yun was, of course, her charming self, seeming to pose while she slept and giving her admirers good views of her while she ate. I was also lucky enough to see little Xiao Liwu roughhousing with his mother and eating thinner pieces of bamboo with great enthusiasm. When I had left on my loan, he was still just nursing, so this was awesome to see.

Mr. Yun Zi was also climbing up his trees in the neighboring enclosure and putting on a show for guests. One of the trees always sheds a lot of leaves, and it was so fun to watch him shake the tree and see how many leaves he could knock off. When I first put him on exhibit as a new little cub, his favorite “toy” we used to lure him out of his bedroom was a dried leaf. Seeing him play brought back those memories of him jumping in piles of leaves and chewing on crunchy, dried-up leaves.

As we get into the cooler months of the year, it’s always fun to watch the different activity levels of the bears and the fun enrichment that comes with it. Come see us soon!

A Mister for Every Panda

Xiao Liwu gets comfy in the tree.

How can he rest like that?

As we move into warmer days, I know a few people watching Panda Cam have commented about seeing some “smoke” in the exhibit. Do not be alarmed! What you see are water misters we have for each panda exhibit. In the wild, these bears do deal with extreme cold in the winter and in the summer experience extreme humidity, but here in San Diego they have been a little spoiled with the nice weather that they so often enjoy.

As we head into summer, keepers have some tools to ensure that our animals are comfortable and can relax to get a break from the heat. The number one enrichment item for the summer is ice. On those hot days, keepers like to go raid the food stands for their ice to give “their” animals something cool to flop down on or sit in. We also make popsicles for them; pandas get applesauce, honey, and chunks of fruit in water that is frozen overnight. For a lot of the Zoo’s carnivores, we make “bloodsicles,” using the juice from the meat they are given, as a cool treat.

Another tool at our disposal is the mister, and it can do multiple things for the exhibit and animal. A mister can keep the dust down in the enclosure and make it easier for the keepers to clean. It also creates a cool place for the animal to sleep in so they can stay out on exhibit for our guests to see. If the area gets too warm, the pandas do have air-conditioned bedrooms as well. I always like to remind everyone that our animals’ well being does come first.

Everyone stay cool out there!

Mr. Wu on View

T13_0244_019It has been about a month since giant pandas Bai Yun and Xiao Liwu have moved to the main viewing exhibit, and what a fun time it has been for San Diego Zoo guests and for our little panda boy! Mr. Wu has adjusted to the new exhibit very well, spending his days exploring every inch of his new habitat, from the ground to the trees. And when he explores the trees, he goes way up high!

Panda cubs are great climbers, and in the wild, high in the trees is the best place for cubs to stay safe. Mr. Wu can be seen lounging 20 to 30 feet (6 to 9 meters) up in the pine tree throughout the day. He is a strong climber and gets up and down with ease. Keepers have also recently installed grass sod in the exhibit, and Mr. Wu is having a great time ripping up the sod and playing with sod chunks.

Xiao Liwu continues to grow like a weed and weighs about 30 pounds (13.6 kilograms). He turned nine months old today! Although he is not yet eating a lot of solid food, he does like to chew on bamboo and really enjoys applesauce. Mr. Wu is still a mellow guy with a sweet personality, and we are all enjoying seeing him grow up and become a “big bear.”

Yun Zi and Hammock Update

Here's another view of the new artificial tree.

Here’s another view of the new artificial tree.

It’s been great to see giant panda Yun Zi’s exhibit go through so many changes in such a short time, and we are not done yet! He will get a hammock. His old one is badly torn up—they don’t last forever with all the use they get. Our Exhibits Team is on the job making a new one, but we have to be patient. They are extremely busy with projects all around the San Diego Zoo. Also, as keepers, we need to find the perfect place to hang the hammock so he will both use it and remain visible for visitors.

It’s been an experience to see Yun Zi sleep at the top of his 15-foot tree—now he can see his mom and baby brother. He is also enjoying the new location of his “lounge chair,” and the guests can now see him up close. Tomorrow, our Horticulture Team is going to help us add new plants and sod to both exhibits. Yun Zi is also continuing his blood-draw training, so we will be able to get a blood sample without using anesthesia. He is excelling with all his training.

Living Life in Front

Xiao Liwu at 6 months old. He has truly mastered tree climbing these days!

For a couple of weeks now pandas Xiao Liwu and Bai Yun have been in the front/main viewing area of the San Diego Zoo’s Panda Trek. The cub is extremely good at climbing up to the top of the pine tree and has even found a spot that previous cubs would frequent to take a nap. I think moving to the new exhibit was definitely an adjustment for the cub. He now seems to have a good handle on being out all day in front of his adoring public.

I know for our visitors it can be a little disappointing coming through the line to only see a distant little fur ball, but as we always say, “The bears run the show.” As a panda narrator at the exhibit, I am often asked when the cub will come down or at what time is he more active, but I can guarantee you that there is no schedule for little Wu and mother Bai Yun! Please be patient and realize that this is normal for him to spend the majority of his time at this age in the trees, just like our previous cubs.

Bai Yun has adjusted beautifully living back in the front. I always remind people that she hasn’t been in the front since July. She has found those favorite spots of hers again and has discovered a couple of new positions to sleep in them. One of her favorites is sleeping in Yun Zi’s old hammock with her head hanging over the side. Bai Yun is staying steady weight at about 230 pounds (Xiao Liwu is 27.8 pounds) and is doing a great job with the cub. He comes down from the pine tree on his own to nurse from her, and occasionally I’ve heard her call to the cub to come down.

I want to assure everyone that Bai Yun is doing everything a panda mother should. She is a fantastic mother, not neglectful or overly aggressive. Something I joke about with staff is that this cub doesn’t get her roughhousing nearly as much as Yun Zi did; Yun Zi liked to poke Mom a lot! Our staff watches Bai Yun on Panda Cam as well, and while the Zoo is open, there is always someone out in the queue watching. In the 14 years that Bai Yun has had a cub with her, we have never had to intervene or raise a cub for her, and we are constantly amazed at what she has shown us through the years here at the San Diego Zoo.
