Fishing Cats: It Takes Two

Fishing cats are native to southern Asia.

Fishing cats are native to southern Asia.

The San Diego Zoo has welcomed the birth of 34 fishing cats over the years, but we have not had a successfully breeding pair of endangered fishing cats since 1999. Our current fishing cat female, Parvati, gave birth to one kitten at the Columbus Zoo in Ohio. But our male, Bullet, is unproven and underrepresented, genetically speaking. It has been keeper Aimee Goldcamp’s sincere desire to see that Bullet has a chance to father some young. Bullet, on the other hand (or paw), isn’t quite as motivated.

You see, Bullet was hand raised at another facility before coming here, and, although he is larger, he is a bit intimidated by his potential mate, Parvati. I was surprised, therefore, when Aimee called me the other morning to say that Parvati was chittering, making the sound an adult female fishing cat makes when she is in estrous and wants the attentions of a male. I dashed over to record this unique sound to share with our blog readers. Yes, I’m always thinking of you!

When I arrived, Parvati was walking around the exhibit, emitting her call now and then. Rather than sounding inviting, the chitter seemed a little angry to me. Guests strolling by the exhibit thought she was telling her keeper it was time for food! But Aimee assured us all that Parvati only makes this sound when she is “in the mood,” and we all felt lucky to hear it. Unfortunately, our gibbon pair living nearby decided this was the time to make their morning territorial hoots and whoops, so it was difficult to record Parvati’s chitters without also getting some gibbon-speak!

Here’s an extremely short audio clip of Parvait’s chitter call:

Still, it was fascinating to watch Parvati pull out all the stops to entice Bullet to come out of the bedroom area and join her in the exhibit. In addition to calling and strolling by the bedroom door, Parvati rubbed her scent on rocks and logs and rolled around provocatively in the sand. Bullet did come to the door to watch her lolling beneath him, but he was unmoved to take action.

It is said that timing is everything, and that is true for cat courtship as well. I learned that the fishing cat exhibit had been closed for some remodeling, with new logs, vegetation, and fencing installed. Bullet had been surprised and a bit unnerved by the changes to his home of six years. Wouldn’t you know it? The day after the exhibit re-opened was the day Parvati felt her maternal calling!

Bullet may still come through for Parvati. After all, “romance” can happen in the off-exhibit bedroom areas as well. There are cameras mounted back there to record any happenings of interest. Who knows—we may yet hear the pitter-patter of little fishing cat paws again!

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.

Fossa: Madagascar’s King of the Jungle

Here is a fossa.

The fossa is Madagascar’s King of the Jungle.

When you typically think of animals at the top of the food chain, you envision large, dominating predators like the tiger, wolf, or polar bear. A new apex predator has moved in along the Big Cat Trail at the San Diego Zoo. It is only the size of a large house cat, but it still dominates the environment it is native to. The fossa is Madagascar’s top predator, but what it lacks in size, it makes up for in unusual and interesting adaptations.

Evolution often works in unusual ways in the confines of an island. With limited space and a limited cast of characters, island ecosystems tend to evolve very unusual and unique organisms. The fossa is a prime example of this. For years, scientists have struggled to classify the fossa; is it a cat, a civet, or something else? The best answer is that a fossa is a fossa, although science now tells us that their closest relative is the mongoose. The fossa specializes in hunting another animal indigenous to only Madagascar, the lemur. To catch highly agile and intelligent prey like lemurs, the fossa must excel in those exact same skills.

Gandalf and Miles are the fossa pair you will currently find on Big Cat Trail. The two usually solitary animals have proven to be very compatible, and we hope that they will breed and produce a litter of pups in the future. Although they eat and spend their time exploring their exhibit separately, they return to each other and cuddle up together to sleep. We have hung perches with rope that will sway so that they can put their super agility to work. They have extraordinarily long tails to balance, and they also have a “wrist” of sorts in their ankle that helps them grip with their rear legs just as well as they do with their front. I’ve observed a fossa who wanted to get a better look at something below it grab hold of a ledge with its rear legs and lower itself down in sort of a reverse chin up. Once its curiosity was satisfied, it simply raised itself back up to the ledge!

The fossa also has an amazing variety of weird vocalizations. It can hiss, snarl, cluck, and make an extremely high-pitched squeal, just to name a few. It must seem like the woods are haunted if you happen to be camping in the woods of Madagascar with a chatty fossa nearby. Listen to the amazing sounds they made during a visual introduction:

Unfortunately, the fossa, like most of Madagascar’s wildlife, has rapidly declining populations. Deforestation in Madagascar is rampant as the human population grows. A balance between the humans and wildlife of Madagascar needs to be found for the fossa and the rest of Madagascar’s unique animals to continue to survive.

Don’t miss your chance to see one of the world’s most unique top-shelf predators. Stop by and visit Gandalf and Miles and see the amazing abilities of these one-of-a-kind animals.

Condor Chick Ready to Fledge

The Condor Cam caught Su'nan perched on the ledge.

Su’nan is perched on the barrier between the nest box and the roost area.

As many Condor Cam viewers have experienced, the rearing process for a California condor can be long and slow. It makes sense, though, for a condor to develop so slowly. She has lots of growing to do! When our chick, Su’nan, hatched on April 29, she weighed approximately 6.3 ounces (180 grams). When she reaches her fledge weight of 17 pounds (8 kilograms) or more, she will have increased her hatch weight by 44 times! In contrast, I have only increased my birth weight by 19 times.

On August 27, at 121 days of age, Su’nan took her most recent step toward leaving the nest: she jumped up onto the barrier between her nest box and the adjoining roost area. She quickly hopped back into her nest, but that’s okay. There’s no hurry to fledge, or leave the nest, just yet. Her feathers still need time to fill in. Hopping up and down from the barrier will exercise her muscles, as well as improve her balance. She has since started hopping into the roost area on the other side of the barrier. Here, she can warm herself in the sun, if she chooses.

Su'nan stretches out one of her fast-growing wings.

Su’nan stretches out one of her fast-growing wings.

While out in the roost, she can also rest or sleep in the shade, perch with her parents (if they are not perched out in the flight pen), or step out to the roost ledge to soak up the sun’s rays for the first time. The ledge is about 8 feet (2.4 meters) from the ground—high enough to make the parents feel comfortable and secure in their nest but not as high as a condor nest in the wild. Su’nan may get near the edge, but she will be cautious in doing so, so she doesn’t teeter off. It is natural for condor chicks to explore and exercise on the edge of their nest cavities. Rarely do they fall out; in 32 years of raising California condors here at the San Diego Zoo Safari Park, we have never seen a chick fall from its nest area.

The next step of Su’nan’s development will be to fledge. When she is ready, she will jump off of the nest ledge. She will either slow her fall to the ground below the ledge or fly to a nearby perch. We consider her fledged when she can get up on a perch by herself. The youngest we have seen a condor chick fledge here at the San Diego Zoo Safari Park is 123 days old. Sometimes chicks have waited until over 165 days. It all depends on the chick.

She's made it to the other side!

She’s made it to the other side!

The parents tend to be very vigilant during this phase of their chick’s development. It could appear overprotective to us, but keep in mind that they have invested an entire breeding season and lots of energy into this one chick. It benefits them greatly to make sure that their sole offspring is safe, healthy, and strong. They usually don’t coax or pressure their chick to leave the nest; on the contrary, we have seen parents make sure a chick doesn’t stray too far from the nest if it’s not ready yet. The parents will usually perch and/or roost near the fledgling.

They also will join her when she finally starts going to the feeding area of the flight pen. Most of the time, though, they will push her aside and eat first, feeding her when they are done. In condor culture, the bigger, more dominant birds usually eat first, while the subordinate birds wait their turn. The earlier Su’nan learns this from her parents, the better she will assimilate into a wild population after she is released. Don’t worry: Towich and Sulu won’t let Su’nan starve. They will continue to feed her even when she is out in the flight pen. Eventually, she will eat more and more on her own.

Her foster parents keep her company in the roost area.

Her foster parents keep her company in the roost area.

Depending on Su’nan’s development and activity levels, we will try to switch the Condor Cam view from the nest box/roost area to the flight pen. You’ll be able to see the roost area, most of the perches in the pen, the feeding area, shade areas created by plants, and the pool, where she can either drink on her own or bathe (one of my favorite condor activities to observe!). The view will be wide, so detail will be harder to discern. Also, we do minimal maintenance in the pen once the chick is large enough to look over the nest box barrier. So the pen has lots of plant growth and dried food (animal carcasses) in it. We limit our activities in/near chick pens so as not to expose the chick to humans, thus desensitizing her to our presence. We have found that chicks raised in isolation from humans tend to be more successful once they are released to the wild. The flight pen won’t look as nice as an exhibit you might see at the Zoo or the Safari Park, but Towich and Sulu prefer it that way, if it means we stay away from their precious chick!

Thanks so much to all of our faithful and dedicated Condor Cam viewers. Soon, your support and devotion will be rewarded when our “little big girl” spreads her wings and takes that next step. Rest assured, though, that Su’nan’s story will be far from over!

Frank enjoys one of his birthday popsicles.

Frank, the biggest gorilla brother at the San Diego Zoo Safari Park, turned 6 years old on September 4, 2014! Keepers threw a birthday party for Frank and the entire troop, complete with paper streamers, decorated cardboard box presents, popcorn, sugar-free popsicles, and a big birthday banner.

With so much to explore out on the exhibit that morning, the members of the troop all quickly spread out and selected their own treats. Frank’s grandmother, 36-year-old Kamilah, claimed the largest decorated box and the popcorn forage pile inside it, while the Birthday Boy preferred the colorful popsicles. Lately, Frank has been trying to demonstrate how grown up he is by carrying his 6-month-old “sister” Joanne around the exhibit. (Joanne’s mother, Imani, had cared for Frank as a baby when his own mother was not able to do so.) Frank enjoys this responsibility so much that he is sometimes reluctant to give Joanne back when her mother thinks it’s time!

Before we know it, Joanne will be big enough to enjoy running around the exhibit on her own and keeping up with her big brother Frank and 3-year-old half-brother Monroe!

He found goodies in each box.

Swazi encourages Qinisa to explore her birthday cake.

There was a lot of anticipation before little Qinisa’s second birthday on August 28. The keepers had prepared a five-layer cake made of ice infused with an alfalfa pellet and soaked beet-pulp mixture. What a treat for an elephant girl on a hot day!

Oooh! It's nice and cool!

Oooh! It’s nice and cool!

The cake was set up in the San Diego Zoo Safari Park’s Tembo Stadium during the 1:30 Keeper Talk, so that Park guests could celebrate with her. Qinisa’s mother, Swazi, was brought into the arena with her. At first, they didn’t seem to notice the cake because they were concentrating on their keepers, who had them run through some husbandry behaviors. When Qinisa had finished her training session, everyone in the audience loudly sang “Happy Birthday.”

Ice cakes are tasty!

Ice cakes are tasty!

Qinisa then explored the arena and investigated her birthday cake. She wasn’t sure what to make of the cake, so she waited until her mom joined her and knocked it over. Satisfied that it was okay, Qinisa then took her time eating little bits of her cake.

The keepers eventually moved all of the elephants back into the main yard and shared the rest of Qinisa’s birthday cake with the herd. What a fun day for everyone!

Two Little Pigs

Warthog youngsters are all legs.

Warthog youngsters are all legs.

Most people would consider the warthog as having a face only a mother could love. On June 7 at the San Diego Zoo, we celebrated the birth of two oinking bundles of joy that definitely disprove this theory!
Our warthogs reside in the spacious exhibit that is located along the speed ramp that runs from the Asian Passage up to Elephant Odyssey. The exhibit is equipped with a large faux termite mound that the warthogs can utilize as a burrow. On the morning of June 7, I knew something was afoot as our male, Kubwa, was resting in an alternate location alone. Kubwa and Lulu are normally side by side, especially when sleeping. Knowing that warthog mothers prefer to isolate themselves when giving birth, I suspected that was what had happened.

For almost three whole days we saw neither hide nor hair of Lulu, but we allowed her privacy as an experienced mom who had successfully raised a litter of three in 2011. Finally, on the afternoon of June 9, I noticed Lulu was out of the termite mound for a bite to eat and a quick, refreshing wallow. Shortly thereafter, a tiny piglet came to the mouth of the burrow. It hopped around a few times, nosed a small clod of dirt, and then quickly retreated back to the safety of the burrow and the comfort of mom. A few days later, I observed two piglets at the same time, confirming that our warthog family had grown by two.

For the next two months we would only catch fleeting glimpses of our piglet pair. Lulu was a dutiful mom, mostly keeping her youngsters in the safe confines of the termite mound. Both the keeper staff and Kubwa gave Lulu a wide birth as she jealously guarded her newborns. Eventually, the piglets became more independent, and Mom allowed them to wander farther from the burrow. They have even become brave enough to grab treats from my hand, after Lulu gets her fair share, of course!

Finally able to get a close look, we were able to determine that we had a boy and a girl. We decided to name them Groot and Mizizi. Groot’s name pays homage to his father, as groot is Afrikaans for large while kubwa has the same meaning in Swahili. Mizizi’s name means rooting, a common warthog activity as they search for food or dig a cooling wallow.

Warthogs are a vital cog to the African savanna ecosystems. Unfortunately for the warthog, they are an important prey for nearly every predator they might encounter. Lions, leopards, hyenas, crocodiles—you name it, and it will gladly eat a warthog. Some larger eagles are even known to prey upon warthog piglets. I’ve watched some very impressive film footage of a female leopard that “specialized” in hunting warthogs. There was even video of her teaching her cubs how to raid a warthog burrow full of piglets while mama warthog was out foraging. This is not to say that warthogs are helpless pushovers. They have long, razor-sharp tusks that they will readily use to defend themselves and, especially, their offspring.

Even though warthogs are considered common, they deserve our conservation attention because of the role they play in Africa’s food chain. Warthogs are often persecuted by humans because of their habit of raiding croplands. They are also unwanted guests because they attract the predators that prey upon them.
Our warthog piglets are growing by leap and bounds each day. Make sure to stop by and get a glimpse of their adorable porcine antics.

World Orangutan Day

Today is World Orangutan Day! On this day, organizations around the globe are highlighting the plight of one of our closest living relatives, the tree-dwelling “person of the forest.” These special creatures are not important just because they are large mammals, or because they remind us of ourselves, but also because they are so integrally connected to the forests they inhabit. With more than 500 known plant species encompassed by their diet, this red ape is a significant factor in seed dispersal in the ancient forests of Indonesia and Borneo.

But the forests, and the orangutans that depend on them, are dwindling. Habitat loss is occurring in Southeast Asia at an alarmingly rapid rate, with Indonesia and Malaysia losing more than 6.5 million hectares (more than 25,000 square miles) in the last few decades. As a result of this habitat loss, the two orangutan subspecies are experiencing a steep decline. The Sumatran Orangutan is critically endangered; the IUCN estimates that no more than 7,300 remain in fragmented patches of forest, primarily in Aceh, Indonesia.

Forest loss in orangutan habitat has a number of causal factors: mining operations and tree harvesting for the pulp and paper industry are two of the usual suspects. But one of the most significant reasons for deforestation over the last twenty years was the rampant growth of the palm oil industry. Production of oil palm, an agricultural commodity that grows only in tropical regions, has skyrocketed: between 1990-2010, Indonesia experienced a 600% increase in land dedicated to the crop. To protect and preserve orangutans, and other species dependent on these forests, conservation biologists have been searching for a way to stem the tide of deforestation due to palm oil expansion.

San Diego Zoo Global has joined the Roundtable on Sustainable Palm Oil (RSPO), and has been working with other North American zoos and RSPO stakeholders to strengthen and improve its efforts to move the palm oil industry toward sustainability. Along with other members of the Association of Zoos and Aquariums (AZA), the accrediting body for North American zoological institutions, we are exploring ways to ensure the preservation of biodiversity in areas impacted by oil palm.

Today, on World Orangutan Day, the AZA has announced its support for the development of a sustainable palm oil marketplace.  AZA member zoos, including San Diego Zoo Global, collectively educate and entertain 180 million guests each year. That is a significant audience that can help push for change that will “break the link between palm oil and deforestation,” a move necessary to preserve orangutans and other wildlife into the future. As RSPO members, SDZG stands alongside the AZA in recommending that North American consumers help to increase the uptake of Certified Sustainable Palm Oil (CSPO) in our supermarkets. Currently, there is more CSPO produced each year than is purchased for consumer goods. Since CSPO is produced in accordance with sustainable principals and criteria as set forth by the RSPO, orangutans would benefit if demand for CSPO were to rise. You can learn more about CSPO, and the product lines containing it, here.

We have a long way to go to ensure that the beautiful, long-haired “person of the forest” remains in wild places in the future. On World Orangutan Day, we ask you to consider how you might actively participate in efforts to preserve our red-haired cousins by beginning your own journey to sustainability. A good first step? Find ways to modify your habits to include more CSPO in your purchases. Together, we can help secure the forest home for the orangutan, and all its jungle brethren.
