Punk Rock Polar Bears?


Polar bears are champion swimmers!

One of the most frequently asked questions during the summer months at Polar Bear Plunge is “Why are the bears green?” The answer may surprise you!

The outer guard hairs on a polar bear’s coat are clear and hollow (like a straw), which means they often take on the color of whatever they happened to roll in. Wild bears mostly have only snow and ice to lie on, so they usually maintain the bright white color that you imagine when you picture a polar bear. Here at the Zoo, we like to provide Kalluk, Tatqiq, and Chinook with as many different substrates in their habitat as we can so that they have options when they choose to rest or roll around. This gives them an opportunity to exhibit species-specific behavior. Throughout their habitat they have access to grass, sand, mulch, dirt, pine needles, hay, and a couple of hammocks made out of used fire hose. You may have seen Chinook masquerading as a brown bear after a prolonged roll in the mulch or dirt.

That brings me back to the original question of “Why are the polar bears green?” Remember those hollow hairs? That tiny space in each hair is a great place for algae to live. The bears’ main exhibit pool is fresh water and during the summer, when the weather is warmer than usual, algae begin to grow on the pool floor. When our bears swim and brush up along the bottom or sides of the pool, they pick up some of the algae, which continue to grow inside the individual hairs! It is not a concern for the bears as we have an elaborate filtration system and excellent water quality team. It is unlikely that they even notice it, but it does give them a bit of a punk rock look. In the winter, around Christmas time, they look downright festive!

The discoloration will last until the bears molt in the springtime. For about two weeks in March to April, our bears glisten with a brilliant white color. Once they start rolling around in all that substrate we provide, they begin to take on the color of their environment and the cycle begins again.

Polar Bears: Summer Update

Handsome Kalluk is back in a non-breeding state of mind, but there are still many things that capture his attention!

Handsome Kalluk is back in a non-breeding state of mind, but remains a curious, active fellow.

In response to recent blog comments regarding Kalluk, the Polar Team wants to assure everyone that he is doing very well. He is rebounding nicely out of breeding season but does occasionally fall back briefly into some breeding season habits. Kalluk has gained a significant amount of weight and some days he eats about 40 pounds of meat! He is once again acknowledging keepers—always a nice change from the height of breeding season when he can be very non-responsive to behavior cues and “hellos” because his focus is elsewhere. He was even was trying to initiate play with me the other day as well as greeting me with his hot, bear breath when I said “good morning”. He also really enjoys a good lip rub again—he pushes his lips past the mesh so keepers are able to make safe contact.

For those who have noticed Kalluk walking around by the waterfall and rockwork in the back of the exhibit, rest assured he is not revisiting his breeding season antics. Behind the rockwork and those doors are the bedrooms where all the bears get the majority of their diet. At various time during the day, keepers call the bears inside to eat their favorite items in private bedrooms. Also in these bedrooms are some comfortable materials they use to make themselves a bed each night. One speculation for Kalluk’s motivation is that he either wants to come inside for food (Yea Kalluk!) or he would like to make a bed by hauling rubber mats, burlap, and boxes to his favorite spot—all of which are behaviors that we are very happy to see. We try to provide opportunities for the bears to create beds on exhibit as well, but we strive to give the bears choices and where they make their bed at night is one important choice. Early in the afternoon, the bears outside get to choose between being on exhibit or going in the bedrooms.

Tatqiq and Chinook are also doing well. You may notice Chinook is looking beautifully plump these days. We purposefully increased her diet significantly this year at this time, to see if it would tip the scales (pun intended) in favor of her chances of having cubs. We really are trying everything we can to make this breeding season a success. Other ways in which we are trying to increase Chinook’s chances (as we have in past years) are allowing her to “choose” her situation (i.e. isolation or with the group), access to air conditioned bedrooms, eventually installing her den, and continuing to study her hormone levels via fecal samples.

As usual, Tatqiq is her “happy-go-lucky” self. She too has gained a little weight, as we intentionally increased her diet. Stay tuned for some exciting projects in the future with Tatqiq!

Other updates include a recent change to the exhibit. We added a new bridge in front of the waterfall. This simple renovation to the exhibit will enable us to make future changes easier to facilitate such as using a bobcat to add more substrate to the exhibit. New substrate is a great source of enrichment and gives the bears more opportunities to make a bed on exhibit.

As the heat increases in the summer months, we do ask for your patience! On those hot days, the bears are allowed access to those nice, cool bedrooms by 3 p.m. PST at the latest in order to give them more choice. Each bear can decide to stay on exhibit (therefore potentially on view for Polar Cam fans) or choose to make a bed inside their bedrooms. Thank you for understanding!

Collared Polar Bear at San Diego Zoo Participates in Energetics Research

She is wearing the collar as part of a U.S. Geological Survey (USGS) project studying energy needs of polar bears that live in the Arctic.

Over several months, polar bear keepers trained the 520-pound polar bear to wear a 2.5-pound collar that measures three types of movement—up and down, side to side and back to front—16 times per second.

The data recorded from the accelerometer will be compared with video taken by USGS researchers of her activity on exhibit. Joining these two types of data will give scientists the ability to read the wave-graphs created by the accelerometer data and understand the behavior they represent, including swimming, pouncing, walking or running. By looking at data from collared polar bears in the wild, researchers will then be able to determine what the bears were doing without needing to observe them directly.

The polar bear’s remote Arctic sea ice habitat makes it nearly impossible to collect these kinds of detailed, direct observations of polar bear behavior in the wild. The data gained from accelerometers on collared polar bears in the Arctic will provide USGS scientists with new insights into the bears’ daily behavior, movements and energy demands, which will be used to better understand the effects of climate change on polar bears.

The San Diego Zoo is home to three polar bears: Tatqiq, her brother Kalluk and another female, Chinook. Polar bears are a threatened species due to climate change-driven habitat loss.

Animals Who Totally Own Winter

With a lot of the US experiencing record cold, and all this talk of another “Polar Vortex,” I thought it would be fun to explore how certain animals deal with extreme cold. Nature has concocted some pretty awesome ways to thrive in cold weather, often involving stylish winter coats, cozy fat insulation, and other clever mechanisms to overcome extreme cold. Check out these animals who absolutely own winter.

Takins have some pretty cool adaptations that help them stay warm and dry during the bitter cold of winter in the rugged Himalayan Mountains. A thick, secondary coat is grown to keep out the chill, which they shed for the summer. Their nose also plays a role in keeping them warm. A takin’s large, moose-like snout has big sinus cavities to warm up the air inhaled before it gets to the lungs. Without this adaptation, takins would lose a large amount of body heat just by breathing.

Polar bears have an outer coat of long guard hairs that stick together when wet and protect a dense, thick undercoat of fur. On land, water rolls right off of the guard hairs. Even though polar bears look white, their hair is really made of clear, hollow tubes filled with air. Scarring or residue on the fur can cause the “white” fur to appear to human eyes as cream colored, yellow, or even pink in the Arctic light. Fat also plays a major role in a polar bear’s ability to survive cold. Fat acts as energy storage when food can’t be found and may provide the ability to generate heat to help insulate polar bears from the freezing air and cold water. This 2-4 inch think layer of fat may also help the bears float in water. Big is beautiful!

Native to the Arctic region of the Northern Hemisphere, the Arctic Fox has a dense, multi-layered coat that provides excellent insulation against the cold. It also has an impressive layer of fat that provides extra insulation, as well as a a specialized body shape that minimizes exposure to cold. This cleverly adapted canine also has fur on its feet to help it walk on snow and ice without issue.


Snow leopards move to different altitudes along with the summer and winter migrations of their prey animals, so their coats vary from fine in the summer to thick in the winter. Snow leopards have a relatively small head with a short, broad nose that has a large nasal cavity that passes cold air through and warms it. Their huge paws have fur on the bottom that protects and cushions their feet for walking, climbing, and jumping. The wide, furry paws also give the cat great traction on snow.


Reindeer originally inhabited the tundra and forests of Scandinavia and northern Russia and were then introduced into Iceland, Greenland, Alaska, and Canada. They are covered in hair from their nose to the bottom of their feet, and have two coat layers: an undercoat of fine, soft wool that stays right next to their skin, and a top layer of long, hollow guard hairs. The air trapped inside the guard hairs holds in body heat to keep the animal warm against wind and cold. The hollow hairs also help the reindeer float, allowing it to swim across a river, if needed.


Sea lions have a thick, slick, waterproof coat that allows them to glide through cold water with ease and comfort. Their flippers also serve to regulate the sea lion’s body temperature. When it’s cold, specially designed blood vessel in the thin-skinned flippers constrict to prevent heat loss, but when it’s hot, blood flow is increased to these surface areas to be cooled more quickly.

Sea Lion

Incredibly adaptable, wolves have inhabited, at one point, virtually all of North America, northern Europe, eastern Africa, and Asia. Employing a wide range of adaptations, wolves tolerate a massive range of temperatures, from -70 to 120 degrees Fahrenheit (-50 to 48.8 degrees Celsius). All of their senses are keen, and they can run, climb, lope, and swim incredibly well.


Lastly, here’s an animal that not only doesn’t wear a winter coat, but is a natural nudist. Yeah, naked mole-rats wouldn’t do so well in extreme cold. Be glad you’re not one of these guys this season. Happy winter everyone!

What to Eat When There’s Nothing to Eat?

Bear ambassador Mi Ton Teiow finds relatively shallow snow, but no food, as the northern winter begins.

Bear ambassador Mi Ton Teiow finds relatively shallow snow, but no food, as the northern winter begins.

The answer? Nothing.

Most of us are familiar with the idea that some bears spend long periods of time in dens, inactive and not consuming significant amounts of food or water. Some bears in some locations survive eating nothing by doing almost nothing. They become inactive, which is sometimes called winter sleep or hibernation. Although you may be familiar with this aspect of bear ecology, have you thought about how incredible it is? These big mammals can go without eating or drinking for months, sometimes while birthing and nursing cubs, yet wake up without bedsores or weakened muscles! This is why the physiology of bears, including that of giant pandas and polar bears, has been a hot field of research.

The only way for a wild American black bear to survive for months without food in the northern U.S. is to save energy by hibernating in a safe, insulated den. The hole to the right of the tree trunk is the only obvious indication that there is an American black bear below the snow.

Although all female bears seclude themselves in dens to give birth to cubs, not all bears enter dens for long periods of time. There’s even variation within species in whether or not individual bears remain in dens or for how long. Researchers have found that in general, bears spend long periods in dens not to avoid cold temperatures, but to reduce their metabolic requirements when there is not enough food to survive environmental conditions. So, in the southern part of their range where their energy balance can remain positive, individual brown bears, Asiatic black bears, and American black bears may not den except to give birth. At last year’s meeting of the International Association for Bear Research and Management (see post, A Whimsical Bear Ambassador Arrives), Lorraine Scotson and Dave Garshelis reported that some sun bears might den for periods of time in the most northern parts of their range, meaning that non-reproductive denning may occur among at least half of the world’s bear species.

The holes melted in the snow are made by the black bear’s respiration.

The giant panda is one bear species that has not been known to den in response to a relative lack of food, and perhaps it cannot do so. During the rare times when all the bamboo plants in an area have flowered and then died, the giant pandas have left the area in search of food; they have not entered dens. Perhaps this is because a bamboo die-off is unpredictable from the giant panda’s point of view, or perhaps this is because a giant panda eating bamboo cannot build up sufficient energy reserves to be able to wait out the lean time in a den, or maybe both factors play a role.

Adult polar bears also do not enter dens solely to avoid food shortages. Pregnant polar bears do spend prolonged periods of time in dens, but biologists think other adult polar bears don’t do so. However, polar bears in some populations regularly fast for extended periods when sea ice conditions don’t allow them to hunt. As for other bears, anything that causes a polar bear to expend more energy, whether inside or outside of a den, or to fast for a longer period of time, makes it less likely that the bear will survive. Climate change is doing just that by reducing the amount of sea ice available to polar bears: the bears expend more energy and go without eating for a longer period of time, creating a great challenge for the conservation of this species (see Polar Bears, Climate Change, and Mi Ton Teiow).

Hibernating bears often line their den with leaves, twigs, and grasses, insulating themselves from the cold ground and conserving additional energy.

The Bear Specialist Group’s Ambassador Mi Ton Teiow recently made a visit to the northern US, where he found plenty of snow but little food for bears. After a short stay in this area, which receives an average of 45 inches of snow per year, the ambassador returned (fled?) back to sunny San Diego, where the last measurable snow fell on the city in 1967. The odds are good that Ambassador Mi will not be snow camping in San Diego any time soon.

Science for Kids: Observing

Do you remember watching panda Su Lin when she was born in 2005?

We are coming up on bear pregnancy-watch season at the San Diego Zoo! Both our giant panda Bai Yun and polar bear Chinook have bred this year, and we are anxiously awaiting signs that they are pregnant. Our fingers are crossed, and all the tools we use to monitor their status are just about ready to go. Of course, we are all excited by the prospect of bear cubs in 2012, and I think it’s safe to say that we will all enjoy the opportunity we have to look into the bears’ dens and observe these ursid moms and their cubs.

An important aspect of our conservation research is the study of animal behavior, which tells us much about the biology of the animals we love and provides us with tools to assess how the animals are doing and what a “typical” animal should be doing during important phases of its life. The study of animal behavior can provide tremendous insights into a species’ biology and gives us tools we can use to help conserve them. While the behavioral data we collect fits into a scientifically devised systematic framework, there is much to be gained from simple observation as well.

I have tried to share the joy of observing animals with my kids in hopes that it will also provide a connection with science and what it means to be a scientist. Often, when we are out and about in our neighborhood or at the park near our home, we stop to watch what the various animals we see are doing. It is amazing how exciting and exotic a squirrel can seem if you really stop and take a few minutes to watch the way it interacts with its environment, the way it responds to your presence, and the various ways it vocalizes and flags its tail to send signals to other animals around it. One of our other favorite animal-watching activities is going on a “bug safari,” which simply entails going into our backyard and turning over a rock. This simple excursion provides a window into the fascinating world of potato bugs, ants, and worms. Very cool!

Panda Cam viewers watched Mei Sheng grow to roly-poly cuteness in the birthing den in 2003.

Another readily accessible way for most kids to experience being an animal behaviorist is to watch our own exotic bears through Panda Cam and Polar Cam. While giant panda and polar bear cubs are undeniably cute, they are also fascinating to watch, and the care and patience the mother bear shows while tending to her offspring is fascinating. After each of Bai Yun’s cubs, our scientific and animal care staff watches the activity in the den in great detail and with unflagging fascination. I love that this very same view into the den will be available to anyone who visits our website.

We are all counting the days to the (hoped for) panda and polar bear births. As part of that, we are making sure that all of our camera systems and microphones are ready in the dens so that we can continue our studies of maternal care behavior in bears. This time around, I hope some young scientists out there will study the bears along with us.

Polar Bears: Breeding Season!

Kalluk and the rest of us eagerly await a polar bear cub or two!

We are all on pins and needles to see if the San Diego Zoo’s polar bears, Kalluk and Chinook, will breed this year. They have always been early birds by breeding in March and even as early as February! But normal breeding time for polar bears is April through May and sometimes as late as June, something we won’t even contemplate! From the looks of how flirtatious Chinook has been and how attentive Kalluk seems, our patience should be rewarded.

We are still participating in reproductive studies looking at hormones excreted in the bears’ urine and feces, but for the most part we still rely on behavior observations. One of the very interesting behaviors we see is with Chinook. Typically, a week before actual breeding and continuing right up to actual, we see her have seizure-like spasms followed by weakness in her back legs. The spasms last only seconds and the weakness only a few minutes. If you don’t know what these are, they can be very scary to see!

But there is no need to worry: Chinook is not alone with these. Most of the other breeding female polar bears show the same behavior. I have asked polar bear biologists who have spent many years observing bears in the Arctic and have sent them video of the process, and they are mystified as to its purpose. Perhaps it plays some role in preparing a female’s legs to hold the male during breeding, since males are usually twice the size, and she may bear his weight for long moments. In the last week we have seen Chinook have these spasms, and over the last few days they have increased both in frequency and intensity. This should be a sign that we are almost there!

We all know what follows: waiting to see if Chinook becomes pregnant and gives birth. I have been getting lots of experience working with polar bear cubs over the last few years since Kalluk and Tatqiq joined us as cubs in 2001. I have just returned from a second visit with Siku, the polar bear cub born at the Scandinavian Wildlife Park in Denmark. My first visit was to share what we learned in preparing our polar bear youngsters for life in San Diego. Siku still was not yet walking then and was not quite 13 weeks old. On my recent trip, Siku was now 21 weeks and was walking, running, swimming, and being overall an adorable monster!

Since Siku’s mom did not produce milk, the decision was made to hand raise him, which meant having close contact with him (not a problem when his fastest speed was a quick crawl!). He is now rambunctious and, as polar bears need to do, he is jumping, grabbing, and mouthing everything and everyone in sight. Mom polar bears are well equipped to handle this; human caregivers, not so much!

This trip was to help the team in Denmark move ahead with management that increases Siku’s independence and encourages his natural instincts as a polar bear. He did extremely well with every challenge of independence. You can imagine how difficult it is, though, for the team who has been caring for him all these months to see that maybe he didn’t need them as much anymore, or at least not in the same ways. I must say how proud I was to assure them and show them the close ties we have with our three polar bears and how much that strengthens when you’re not worried about when the next play jump comes from a now 60-pound and often wet white ball of teeth and claws! All meant in fun, but still dangerous for fragile humans!

Siku has lots of toys to encourage his natural learning behavior and is getting plenty of opportunities to learn with his training sessions. At 21 weeks, he has already learned several important behaviors from his keepers such as “sit,” “stand,” “down,” “shift,” “come,” and how to sit on a scale.

In choosing his name, thought was given to the chance to represent wild polar bears and the people who share the Arctic. Siku is from the Inuit language for sea ice. Siku will remind everyone that we are losing our arctic ice due to warming trends in our climate.  Science has proven this warming is caused by the increase of carbon emissions in our atmosphere. Siku and our three polar bears, Chinook, Kalluk, and Tatqiq, are ambassadors who remind all of us of their wild cousins and that we must make changes to help save their arctic home.

As you enjoy watching and hearing about these great ice bears, please keep in mind everything you can do to help. Then do it!

UPDATE: Two days after this was written, Kalluk and Chinook began breeding. November 2 is the first possible day of birth if Chinook is pregnant! The waiting begins. . .


Polar Bears: No Easy Answers

Ah, Chinook!

November 16 has come and gone and still no news with Chinook. The estimated gestation for polar bears is 195 to 265 days; since Kalluk and Chinook bred in mid-February, we certainly expected to know by now if Chinook is or isn’t pregnant.  All we know for certain is that she has not had any cubs . . .yet.

Her hormone analysis shows similar profiles to other polar bears that have given birth in late November or December. It is also a profile that has not produced cubs. Every year we get a bit better information, but it is still not the perfect test. Chinook’s ultrasound exams also showed promise of her uterus developing as we’d not seen in past years. We also had two exams scheduled where Chinook let us know she did not want to join in. However, this week she enthusiastically participated. We easily could see her uterus but no cubs were to be seen.

So for now we have no easy answer to the question “Is she or isn’t she?” We will continue to care for her as she needs until the time that she shows us she is ready to be out with Kalluk and Tatqiq, and then we’ll have our terrific trio together again or until our beautiful girl has those precious white fur bundles, and we can all know our finger crossing and wishes worked!

Little Polar Bear: Lessons

Qannik demonstrates the paw to hand behavior. What a smart cub! Photo by Andrew Fore.

JoAnne was at the Louisville Zoo in Kentucky to help staff with their newest arrival, an orphaned polar bear cub named Qannik. Read her previous post, Little Polar Bear Orphan.

For polar bear cubs, life is all about learning to survive in the Arctic from the moment they are born until Momma kicks them out. Momma bear has all the right stuff for teaching: intelligence, nourishment, and communication. For Qannik, communication with her keepers would be the first lesson. Luckily, Qannik is very intelligent, and, dare I say, so are keepers! Training using positive reinforcement is how we communicate with our bears.

The sloping false bottom made for Qannik's pool.

We taught Qannik to slurp her formula out of a large syringe that is easy to use from outside the mesh. Qannik is a large girl now and will soon be reaching over 400 pounds (180 kilograms), so it’s important we teach her just as we would when she is an adult polar bear. This beginning relationship is so important: we look for nice, relaxed eye-to-eye moments. Next are a few simple behaviors like shifting rooms, sitting, or presenting a paw when asked to do so.

While the Louisville Zoo keepers were flying to Alaska to pick up Qannik, one of my tasks was to build a false bottom in her new pool to help her learn how to swim. In the Arctic, Momma bear offers her back for the young cubs to hold on to until they learn to swim well. With the help of Steve Goodwin, Louisville Zoo’s all-round-can-do-it-all guy (he makes incredible pottery, too!), we built, netted, tied, and lashed a false bottom into the pool. The design allowed for sloped access into the deep end, strength enough to hold a pouncing 60-pound (27 kilograms) bear, and be easy to take apart once Qannik could swim and get out of the pool on her own.

Qannik keeps everyone in suspense as she contemplates a swim.

The day after Qannik arrived, we watched her make her first plunge into the pool.  Miss Qannik knows how to hold her audience! She spent the majority of the day on the first steps holding on by her toes, stretching ever so far that we all knew she had to go in! She would turn and look at us as if to say “Gotcha!” Finally she rewarded our patience by a not-so-graceful dive into the pool after a white bucket toy.

After the first excitement we held our breaths: would she be able to get out of the pool? Well, of course—she’s a polar bear! At that moment we decided we could take the false bottom out of the pool, as it had done its job! The slope helped her with gradual ease into the pool, it was strong enough to hold her, and was easy to take apart. Did you know little polar bears are also helpful? Qannik hopped right back into the pool and began to dismantle the false bottom to the floor. Louisville Zoo keepers report she now throws all her toys into the pool and is officially a swimming maniac.

Qannik helps dismantle the pool's false bottom, as it's no longer needed.

When the time came to say goodbye to little Qannik, it was not without a lump in my throat. In just a week she had grabbed my heart for all she has been through in her short life. What a spirit—so tenacious, so tough, so intelligent, so irresistible, a connection to the wild. All polar bears are like Qannik. It’s hard to think that there will be more Qanniks to rescue and some that we won’t find.

My time with Qannik was also about the wonderful folks who all came together to rescue and care for this little bear and the great team that will be there when the next bear needs help. We can make the changes as individuals joining together into communities to collaborate on conservation to save our arctic ice and the beautiful spirited creatures that live there.

Be sure to share some time with the San Diego Zoo’s fabulous trio on Wednesday, July 13.  We hear we are in for a summertime snow fall!
