Pandas On and Off

Changes are happening at the San Diego Zoo, and all for the better, of course! Ground was broken for our new Asian leopard habitat, to be located next to Panda Trek in our Panda Canyon (see NEWS blog dated October 9). With the preparation and construction of this wonderful new home for our snow leopards and Amur leopards comes noise. We try to keep noise to a minimum in our giant panda area.

Bai Yun seems to take almost all construction noise in stride—she’s had years of experience at the Zoo! Her son Xiao Liwu has been the least bothered by noise of all six cubs Bai Yun has raised. Still, as construction progresses, panda keepers may take “Mr. Wu” off exhibit from time to time or move him to the north yard if they find he is bothered by the noise. He could still be seen by our Panda Cam viewers but not by Zoo guests. Gao Gao will continue to remain off exhibit during this time.

Where there's 'boo, there's bliss!

Where there’s ‘boo, there’s bliss!

But the good news is that a television monitor tuned to Panda Cam has been installed in our main gift shop! If you come to the Zoo, you can check on Panda Cam to see who is visible before making your way down to Panda Trek. And our wonderful volunteer Panda Cam operators will always strive to give you the best possible view of one of our pandas.

Understanding Wildlife Trade In Asia

A sign outside a store in Luang Prabang, Laos, advertises ivory for sale.

Typing this from a café in Laos, I am thinking about and facing one of the greatest threats to biodiversity: the illegal trade in wildlife and wildlife parts. I’m looking at a sign in a shop across the road, advertising elephant ivory for sale. Recently, I walked through the local night markets, with wildlife parts such as muntjac horns, turtle shells, pangolin scales, bear teeth, leopard cat teeth, and wild pig tusks, among others, for sale. Earlier I passed a restaurant that had two macaques in tiny cages. Last week, I passed a house in an upscale neighborhood of Phnom Penh where a brave wild bear cub (its mother killed by a snare in the forest) escaped its tiny cage, scaled the wall, and landed in the pool of the boutique hotel next door. Thankfully, the cub was rescued and is now being rehabilitated in the Phnom Tamao Wildlife Rescue Centre.

Last week, I passed a house in an upscale neighborhood of Phnom Penh, where a brave wild bear cub (its mother killed by a snare in the forest) escaped its tiny cage, scaled the wall, and landed in the pool of the boutique hotel next door (see photo). Thankfully the cub was rescued and is now safe and being rehabilitated in the Phnom Tamao Wildlife Rescue Centre.

A three-week-old Asiatic black bear cub is one of a pair of cubs rescued from the wildlife trade and now being cared for at the Phnom Tamao Bear Rescue Centre in Cambodia. It is destined for a wonderful life in the forest.

Of all the species we work with at the San Diego Zoo Institute for Conservation Research, by far the most complex and dynamic are humans! Numbering over 7 billion, with countless cultures, motivations, and world views, humans are an extremely complex, yet central element in conservation initiatives. Successful conservation requires a multipronged approach, tackling the biochemical, ecological, and behavioral aspects of wildlife and the cultural and economic countenance of humans.Our Conservation Education Division focuses on the socio-ecological aspects of conservation across three main themes: conservation education, conservation social science, and community-based conservation. As a community-based conservation ecologist, I focus on the intersection of wildlife and humans, using both ecological and sociological research methods to inform our projects, which is why I am in Southeast Asia.

Three of the 20 Souphanouvong University students who, after participating in our training workshop, partnered with us to conduct wildlife surveys in Laos. They are conducting surveys at the Tat Kuang Si Reserve in Laos.

With its dense, tropical forests, rich biodiversity, and large human populations, Asia is a center of wildlife trade. Despite many countries having made capturing, poaching, killing, and exporting of wildlife illegal, poaching and consumption of wildlife still abounds. The history of wildlife use in Asia is a long and ingrained one, where for over 3,000 years wildlife has been used for food, traditional medicine, entertainment, and decoration. It’s embedded in many cultures here.

Couple that history to the rapidly developing economies and expanding middle class here, and it has meant a continued (and growing) demand for wildlife products, many of which are regarded as status symbols. Tackling such normative aspects of culture to try to curb this tide of wildlife use, and to eliminate demand, is a big challenge!

The Free the Bears team designs and refines the survey instrument for Cambodia.

Since the beginning of September, I’ve been in the field collaborating with our partners at Free the Bears. They are dedicated to conserving Southeast Asian bears, specifically the Asiatic black bear Ursus thibetanus and the sun bear Helarctos malayanus. These species are poached from the forest and killed for their gall bladders. The cubs are captured and placed in bile-harvesting farms where, confined in small cages, bile is periodically withdrawn from their gall bladder using a large needle over the next 10 years or so. Both species are also killed for their paws, which are used in bear paw soup and bear paw rice wine, and for their claws and teeth, which are used for decoration. Lastly, cubs of the killed parents are taken for the pet trade.

A recently rescued sun bear is in quarantine before being released to the forest enclosures in the Phnom Tamao Bear Rescue Centre in Cambodia

Free the Bears staff patrol for and remove snares from the forest and actively rescue bears from confinement. We are supporting this work by developing and conducting human dimension surveys about wildlife in Cambodia and Laos. Our collaborative project employs a novel approach to understand people’s knowledge, attitudes, and beliefs toward wildlife and to learn about their usage of bears for parts and pets. Understanding how people think about and view wildlife is vital for developing conservation interventions, especially when tackling wildlife consumption. It will also form the foundation of future communication and education efforts about wildlife. People’s attitudes often drive their behaviors; by better understanding attitudes, we can more effectively affect behaviors.

A sun bear does what it does best: living a free life in its native habitat.

In Cambodia, we are conducting face-to-face interviews with people about their knowledge and attitudes toward wildlife. We are using a randomized response technique (RRT) to ask about wildlife usage. Why? When you ask people about illegal activities (such as drug-use, DUI, etc.), they may not answer truthfully, so data may be biased or unreliable. RRT uses a randomizing device (such as dice or coin flip) that allows the respondent to answer truthfully while maintaining anonymity. Even the interviewer does not know their response! For Cambodia, we are basing our RRT around a local dice game called khla-kluk.

Students at Souphanouvong University in Laos are excited to help out conservation after our workshop.

In Laos, we’re using a different approach. We’re asking people to complete a self-administered questionnaire, which we have translated into several languages (see images). We partnered with the Women’s Union and Souphanouvong University students, whom we trained to conduct surveys. With this wonderful team of 30 citizen scientists, we have collected over 700 surveys. By the end, we will have over 1,000. This is a fantastic response and the first of this scale in Laos.

We are grateful to the governments of Cambodia and Laos for their bold action around making wildlife trade illegal and for allowing us to conduct these surveys. We are also grateful to our many local partners, who are doing the hard work of administering the surveys in the coming months. It is hoped that we can adapt this survey for use across Southeast Asia and India in a comprehensive assessment of wildlife usage.

David gives a lecture (via a translator) about conservation in Laos.

It is through efforts like this, and the incredible work of the Institute, San Diego Zoo Global, Free the Bears, and others that I can stay hopeful, even as I look at wildlife products for sale. Why? Because we’ve not given up, and we are working in smart, complementary, and sustainable ways to tackle these threats so that humans and wildlife can co-exist.

Thanks to you for your continued support, which makes this work possible.

7 Animal Facts You Didn’t Learn In School

You don’t have to be an animal expert to appreciate the natural world. In fact, simple short cuts like the fun facts listed below, can be very conducive to gaining a better understanding of the Animal Kingdom. Enjoy!

Monkeys have tails and apes don't.

1. Monkeys have tails and apes don’t.
Since we have more in common with our great ape cousins than we do with monkeys, a good way to remember this fact is to simply look at your rear end.

There’s no such thing as a poisonous snake.

2. There’s no such thing as a poisonous snake.
Contrary to pop culture and older versions of Encyclopedia Britannica, snakes are venomous, not poisonous. If they were poisonous, touching or licking a serpent would be the more appropriate fear than death by snakebite. And that’s even debatable, since statistics show that out of 7,000 to 8,000 snakebites per year in the U.S., only 5 or 6 are fatal. Call it semantics, but the truth is only 10 percent of the 3,000 species of snake are venomous, meaning they inject toxins into their prey (biting or stinging). The difference is skin deep.

Well, Chinook?

I snapped a photo of this bear from the Polar Cam. Any guesses as to who looks so relaxed?

I snapped a photo of this bear from the Polar Cam today. Any guesses as to who looks so relaxed?

Polar bears have, what seems to us, a long gestation period. A fertilized polar bear egg doesn’t implant or develop right away. Instead, it implants when triggered by the female’s body condition and environmental factors, most often between September and November. This is known as delayed implantation, an adaptation that ensures cubs are born to healthy mothers at a time of year when their chances for survival are greatest. We are in the middle of that time zone right now with our female bear, Chinook. If a fertilized egg were to implant, the actual fetal gestation would be about 60 days.

Keeper Samantha Marino explained that Chinook is starting to be come interested in using bedding materials and desires more “alone time” from Tatqiq and Kalluk on a more regular basis. Keepers are offering Chinook denning/nesting materials, such as Bermuda grass, burlap, and palm fronds, and allowing her to spend the afternoon away from the other bears. They will continue to monitor this behavior and give Chinook what she needs for a possible pregnancy.

Chinook’s urine and feces are collected and sent to our Endocrinology Lab several times a week to determine if there are any changes in her hormone levels that might indicate that hoped-for cubs are on the way. And currently, Chinook is just on exhibit in the morning; in the afternoon and evening, she gets to enjoy the privacy of the off-exhibit polar bear yard, which includes access to the bedroom area.

We will certainly let polar bear fans know if anything changes, but for now it’s just a waiting game. Paws crossed!

Watch the bears daily on Polar Cam…

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!

Panda Bai Yun’s Tooth

 

Dr. Sutherland-Smith used a light to seal a dental composite during a restorative dental procedure on Bai Yun.

Dr. Sutherland-Smith used a light to seal a dental composite during a restorative dental procedure on Bai Yun.

Yesterday morning, September 10, a dental procedure on giant panda Bai Yun was performed by a team of veterinary service staff. I was fortunate enough to attend and watch! The whole experience was fascinating to observe, and I was impressed at how diligently the San Diego Zoo’s veterinary team cared for and treated our beloved Bai Yun.

The reason for the procedure was that keepers had noticed there was a chip in one of Bai Yun’s lower canines. As most of you know, giant pandas use their teeth to chew and break apart bamboo, tearing apart the stalks to look for the culm (soft, inner tissue of the bamboo). A chip such as the one in Bai Yun’s canine isn’t uncommon, especially for a panda of her age. Remember: she just turned 23!

In order for the veterinary team to get a close look and perform a dental exam, Bai Yun needed to be taken to the San Diego Zoo’s Jennings Center for Zoological Medicine. Once Bai Yun was anesthetized at the Giant Panda Research Station, she was carefully transported to the on-grounds veterinary hospital so staff there could get a closer look at the canine in question. They performed a dental exam and took some X-rays of the chipped canine tooth, after which they concluded that a restorative procedure could be done to fix the tooth. A warming blanket kept Bai Yun’s body temperature at a comfortable level. Surrounded by all of the vet team members and their equipment, I was surprised that she seemed smaller to me than when I see her in her exhibit. Crazy, huh?

Dr. Meg Sutherland-Smith, who is our associate director of veterinary services,  filled in the chipped part of the tooth with a dental composite and then used a special light to cure the composite. Dr. Sutherland-Smith noted that originally they had some concerns that the pulp canal of Bai Yun’s chipped canine had been compromised, but she was happy to report that it wasn’t compromised after all, and she noted that the restorative procedure should help prevent any further chipping or deterioration.

After the dental procedure was completed, a veterinary technician performed a dental cleaning on all of Bai Yun’s teeth and then assisted as Dr. Sutherland-Smith took a few images inside Bai Yun’s mouth with a specialized dental camera. Bai Yun was then transferred into a panda transport cage, which allowed her to wake from the anesthesia while still being in the veterinary hospital’s treatment room. Veterinary staff closely watched as Bai Yun woke up, monitoring her breathing and vital signs throughout the process. I checked in with our panda team a few hours later to get an update on Bai Yun. The team reported that Bai Yun was doing great and was comfortably resting back in her own bedroom suite.

Watching this dental procedure was such an incredible experience. It showed me firsthand how hard our animal care teams work to care for our animals at the San Diego Zoo.

Scents for Polar Bears

Kalluk thinks snow is the PERFECT enrichment for polar bears!

Kalluk thinks snow is the PERFECT enrichment for polar bears!

Lions and tigers love perfume and giant pandas enjoy the smell of cinnamon, but do the San Diego Zoo’s polar bears get a kick out of scent enrichment, too? Keeper Matt Price explained to me that although our Arctic bruins have impressive sniffers, they don’t go all crazy rubbing around in smelly things like some critters do!

Keepers do have an impressive arsenal of scents on hand for the animals in their care. Various perfumes, essential oils, spices, and even synthetic urine from other species are used from time to time to give our Zoo animals something different to experience, investigate, or delight in. The big cats and pandas roll around in the scent, seemingly trying to spread it all over their body. But the polar bears’ reaction is different: they give the new smell a good sniff and then go on with whatever activity they were doing—no big deal! So instead, Matt or his fellow keepers make a scent trail that leads the bear to a big payoff—an extra-special food treat or new toy. The bear follows the smell to the prize!

There is one type of scent enrichment that DOES get more of a reaction from our polar bears: camel and llama hair. Keepers collect the shed hair and place it in small piles for the bears, who roll around in it with great gusto!

Gao Gao: Class Clown

Gao Gao was busy munching on his leafy bamboo this morning. Image taken from Panda Cam.

Although our senior panda, Gao Gao, is still off exhibit, he is much improved after his May surgery (see post Surgery for Gao Gao). I spoke with Gaylene Thomas, animal care supervisor, to get the latest scoop on Papa Gao. She said he had additional dental work performed on a damaged/worn molar in June, and that procedure seemed to help guide him down Recovery Road—his appetite and energy have returned!

Being a born bamboo-eating machine, Gao Gao had always preferred to eat the thick bamboo culm, which was so hard on his teeth, rather than the much-gentler leafy bamboo. And that was just at the feedings when he was even interested in food; leading up to his May surgery, Gao Gao frequently exhibited lethargy and loss of appetite. But these days, our senior panda has taken to eating the leafy bamboo with renewed gusto, so there is no need to provide the thicker stuff for him. He is more active and animated, often exploring his yard and playfully seeking his keepers’ attention. Sometimes he does his playful antics to elicit tactile interaction: back or head scratches, provided by the keepers with the use of a wooden back scratcher. But sometimes he just does them to make his keepers smile! Who knew Gao could be such a clown?

So why do we continue to keep him in the off-exhibit north yard? Plain and simple: the Panda Team still wants to keep a close eye on him, and that side of the Giant Panda Research Station has a larger air-conditioned bedroom for him and much easier access to the area where his blood pressure is monitored. Gao Gao is eager to participate in these sessions once again, with apple slices and honey (or perhaps just that extra attention?) as his reward. Whatever the reason, Gaylene shared that she is “really happy he’s doing so well.” Me, too!

Panda Xiao Liwu is Two

Xiao Liwu's birthday cake was a thing of beauty!

Xiao Liwu’s birthday cake had a beach theme, complete with tiki torches!

Our birthday boy picked an especially warm day for his party, and who knows how long his ice cake will last, but it was a thing of beauty! The two-year-old panda’s party had a beach theme, so his exhibit was decorated with cardboard beach balls, jellyfish, and seahorses dangling here and there, cardboard gift boxes, and a pile of wood shavings to represent beach sand.

The birthday cake was topped with a large blue “2,” which didn’t stay upright for long, and an orange “tiki torch” on each side. Mr. Wu seemed delighted with his surprise, climbing up on it to get every last bit of apple. When, most likely, his tongue and bottom got too cold, he retired to the log bridge to nap in the warm sun.

_A3P4966

Our cake team spent several weeks preparing this special treat for Xiao Liwu. It was about 4 feet (1.2 meters) tall, weighed over 100 pounds (45 kilograms), and had layers supported by bamboo poles. It was so colorful, too! Bright blues and oranges. Knowing that apples are “Mr. Wu’s” favorite snack, the team filled the cake with apple slices frozen in the ice blocks. Slices of carrots, yams, bamboo, and more apples were arranged in a depression on the top of the cake, which was drizzled with a yam paste “frosting.”

If he gets too warm today, he’ll still have that beautiful ice cake to sit on! Video of Xiao Liwu enjoying his morning when it becomes available, so be sure to check back. (Update: video has been added. Enjoy!)

Xiao Liwu and Water

Come to Mr. Wu, bamboo!

Come to Mr. Wu, bamboo!

What is it about water and Mr. Wu? San Diego Zoo Keeper Jennifer Becerra reports that our precocious panda boy enjoys playing with tubs of ice cubs—and has even fallen asleep atop the ice in the tub. But once that ice has melted, out he comes! To encourage foraging behavior, keepers gave him the opportunity to bob for apples—but once he got his paw wet, the game was over.

Other attempts to get Xiao Liwu, who is almost two (sounds like a line from How the Grinch Stole Christmas, doesn’t it?), to forage for his food have failed. Wu does NOT like to work for his food. As Jennifer admitted, he is definitely Gao Gao’s son in that regard!

Thankfully, other forms of enrichment have been appreciated by the mini Gao Gao. You may have observed him resting on a “pillow,” a burlap coffee-bean bag filled with hay. And he has a new favorite scent: gingseng root. His blood pressure/blood draw training is progressing nicely, and he now rolls onto his side when asked—another training milestone.

Don’t tell Wu yet, but a birthday ice cake has been ordered for his big day on July 29. He should enjoy it, as long as it doesn’t melt!
