Devi, Cover Girl

caption

Five-month-old Devi is a bundle of energy with a personality all her own!

Have you seen the August 2015 ZOONOOZ? Hippo calf Devi is the “cover girl”—complete with a model-like, pouty lip. Devi is now five months old and has been growing in both size and personality. It wasn’t that long ago we were straining to get a glimpse of the shy, skittish calf tucked under the chin of Funani, her almost 3,500-pound mom. Nowadays, Devi is doing underwater barrel rolls and cartwheels while Funani tries to keep up! Often, Funani rests her big head on her calf’s back to keep her still, if only for a minute. But if Devi isn’t ready to settle down, she wriggles free to go on to her next adventure.

Some of you might wonder: “When is this happening? Every time I go see them, they are sleeping.” Hippos are naturally nocturnal, meaning they are active at night. Here at the Zoo, the best time to see them active is after they’ve finished breakfast in the barn and go back out to the exhibit—usually right as the Zoo opens—and then later in the afternoon. But keep in mind that, depending on their mood and weather, they can be active anytime.

caption

Devi often likes to get right up to the window to watch the visitors.

If you witness one of their active times, you will see Devi’s personality shine. There is only one word to describe her: sassy. She often ventures up to the glass to gaze at the visitors while Funani gently nudges her to move along. Then, if they pause on a ramp or a rock, she might initiate a play session with mom. Devi will start with a quick head toss that turns into a nibble on her mother’s ear or mouth and then, ever so gently, Funani opens her large mouth (exposing those enormous teeth) and thus begins the session.

These sessions are teaching Devi valuable life lessons on how to maneuver if and when she has to fight, but for us onlookers these sessions are sweet and smile inducing. Their play sessions on land are something to see, too! Mostly, it’s Devi trying to check out everything around her as she head tosses, nose bumps, bounces, and pivots all at a pace much quicker than Funani who is trying to make sure her “little one” doesn’t get into trouble. It is common to see or hear Funani snort at Devi if she needs to reign in the sass. You can “see” the snort when they are in the water—it’s when a rush of large air bubbles suddenly come from Funani’s nostrils. If you watch closely, you’ll see Devi will change her tune after a snort from mom…usually.

Funani and Devi are scheduled to be in their habitat on Hippo Trail Tuesdays, Thursdays, and weekends. As always, the schedule is subject to change depending on their needs, but try to come by and see the sassy sweetie soon!

One Step Closer To Fledging

Antiki has moved out of the nest box, spending her time on the ledge outside where her parents groom and feed her.

Antiki has moved out of the nest box and is spending her days on the ledge outside where her parents groom and feed her.

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, Antiki, hatched, she weighed approximately 6.35 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! I, myself, have only increased my birth weight by 19 times.

On August 6, at 118 days of age, Antiki 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 later hopped back into her nest, but that’s OK. There’s no hurry to fledge, or leave the nest, just yet. Her feathers still need time to fill in all of the way. In the meantime, hopping up and down from the barrier will exercise her muscles, as well as improve her balance. On August 11, she hopped into the roost area on the other side of the barrier for the first time. Here, she can warm herself in the sun, if she so chooses. 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 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. Antiki 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 33 years of raising California condors here at the San Diego Zoo Safari Park, we have never seen a chick fall from its nest area prematurely.

The next step of Antiki’s development will be to fledge. When she is ready, she will jump off of the 8-foot-high 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.

The parents tend to be very vigilant at this phase of their chick’s development. It might appear over-protective 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 that it 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 they will 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 Antiki learns this from her parents, the better she will assimilate into a wild population after she is released. Don’t worry—Sisquoc and Shatash won’t let Antiki 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.

Depending on Antiki’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 and into the pen. 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 Sisquoc and Shatash 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 Antiki’s story will be far from over!

Summer Pandas

caption

Xiao Liwu got a swing for his birthday—the perfect gift for this active young bear!

The end of the Zoo’s longer summer hours is in sight, and our animals are getting hit with another big heat wave. This year has been a more mild summer as a whole, but we have had some small sprints of heat. Many of you, visiting or watching, have noticed that Gao Gao has spent many of his summer days in the air conditioning. While this has been frustrating for our guests visiting, please know how much we appreciate your cooperation while we get Gao Gao bear through summer.

While Gao Gao has been relaxing most of the day, Xiao Liwu has been quite a character to watch! Throughout the day we have observed him having random energy bursts, and showing off to our guests. Remember this is normal for a panda as they go through their first hormone shift at three years of age! For those of us that have been watching him since birth, up close, it’s great to see him really exhibit these bear behaviors.

I have had the amazing opportunity to watch five of our panda cubs go through their first hormone shift, and it NEVER gets old. Right now I can honestly say that there is no perfect time to come visit the pandas for good activity levels; there are mornings where Mr. Wu is entirely on FOOD mode, there’s SLEEP mode, and then there’s DEMO mode! Right now, he has been eating for several hours a day, no specific time, and there is almost always a time where he is running, rolling around, and jumping on stuff in his enclosure.

Bai Yun is still in our behind-the scenes-area. As many of you know, our vets have come to the conclusion that she is not pregnant. While we are of course disappointed, we are glad that she is healthy and doing well. Our keepers will be working with her on a daily basis, and getting her out of her den and outside into her garden room. This is a process in itself. Making sure she’s comfortable is their number one priority and they are easing her back into her normal routine.

So thank you again for your understanding and helping us keep our animals comfortable—remember that in the heat of the day none of our bears are really going to want to be up and about! And this coming week, drink lots of water while you’re visiting us at the Zoo!

Ahoy! Let’s Celebrate Xiao Liwu’s Birthday!

caption

Flashback to Xiao Liwu’s first photo at about a month old. Oh, that face!

Xiao Liwu’s 3rd Birthday is July 29th  but we are going to have his big party on August 1st for him, beginning at 9 a.m. (US Pacific Daylight Time), so mark your calendars and set your alarm!  We are looking forward to seeing what his ice cake (crafted by our creative Forage Team) looks like this year. We as a team always enjoy this little surprise and the only hint we have had is that it is orange. (You can read about how an ice cake is made here.)

“X marks the spot” when the Forage Team delivers the cake at 8:45 a.m., while we keepers put out all his enrichment.  The birthday boy will be able to come aboard his exhibit at 9:15 a.m., right after the Zoo opens so all of his crew and friends can be there to watch him enjoy his cake and “presents.”  Mr. Wu  has commandeered the cave exhibit, so his fans will have a bigger space to view the celebration.  This is also the better exhibit for Panda Cam viewing so all the Panda Fans that cannot be there in person can celebrate with us, too!

Mr. Wu still is our “Little Gift” and amazes us everyday. He is now 149.6 pounds (68 kilograms) and is still small but mighty. He has been going through the destructive phase, testing the limits of every climbing branch and log in his exhibit.  So be ready for the fact that there may be times that he falls or gets a new scrape, just like any young boy would.  He has many playful bouts of running around and enjoying his enrichment, but he still remains patient during his training sessions.  We have taken a little break with his blood pressure readings, as Bai Yun has been having full access to the training crate.

As keepers we look forward to this time to give all our pandas extra enrichment in celebration of this milestone—another year closer to being an adult (which usually is around five years of age).  If you are able to come to the celebration in person, please also stop over at our Volunteer table to learn about giant pandas and look at our special artifacts.

We know one day that Mr. Wu will add to the genetic diversity of future giant pandas and maybe even one day his future cubs will be candidates for release into the wild. In this way and so many others he is a “Little Gift” that keeps on giving!

Condor Chick: Getting Big!

caption

There she grows! Antiki is feathering out nicely.

Antiki, our California condor chick featured on this year’s San Diego Zoo Safari Park’s Condor Cam, is now over 100 days old and starting to get her “big bird” feathers! As many of our regular viewers have noticed, her flight feathers are growing in. Some of the first feathers that start to grow are the wing feathers. It is easy to see the feathers growing through the chick’s down—the down feathers are gray, but the new flight feathers are black. The long feathers that grow from the tip of the wing are called “primary feathers” and the feathers from the wrist to the armpit are “secondary feathers.” Primary and secondary feathers are the giant feathers that make the California condor’s wing so large and impressive; an adult can have a wingspan of up to 9 ½ feet! We are estimating our chick’s wingspan to be around 5 feet right now—between the size of a red-tailed hawk’s and a bald eagle’s. Her tail feathers are also starting to grow. They’re a little harder to see on camera, but you should be able to spot them soon.

After the wing and tail feathers fill in, the feathers on the chick’s back will start to grow, as well as the small feathers on the top of the wing (called “coverts”). Even though many new, black feathers will be covering parts of her body, she will still have lots of gray down showing, making it easy to differentiate her from her parents. Eventually, her light-colored skin will turn dark grey or black and be covered with fine, fuzzy feathers, but this won’t happen until well after she leaves the nest. Her skin will stay dark until she reaches maturity at 6 years and it turns pink-orange, just like her parents’, Sisquoc and Shatash.

The chick had her second health exam on June 25 during which our veterinary staff were able to administer her second, and final, West Nile virus inoculation. A blood sample was obtained and she weighed in at 13 pounds, 7 ounces (6.1 kilograms), over half of her projected adult weight. Even though our little girl is getting big, she still has room to grow!

The adult condors normally are fed four days per week. The other three days of the week, they are fasted. They often will not eat every day in the wild, sometimes fasting for up to two weeks, so our nutritionists recommend not feeding them every day to prevent obesity and food waste. Their diet, depending on the day, can consist of rats, rabbits, trout, beef spleen, or ground meat. We offer two to three pounds of food per bird per feeding day. When the condors are raising a chick, in addition to their normal diet, we offer extra food every day: 1 rat, 1.5 pounds of beef spleen, 1 trout, and half a pound of ground meat. They don’t end up feeding all of this food to the chick, but we want to be sure that they have enough for the growing baby. It’s difficult to calculate exactly how much food the chick is eating each day, but we estimate that she could be eating 1.5-2.5 pounds of food per day.

Many Condor Cam viewers have seen some rough-looking interactions between the chick and her parents. What may have been happening was a form of discipline. As the chick has gotten bigger, her begging displays and efforts have gotten more vigorous. These efforts can sometimes be bothersome or problematic for parents that just want some peace and quiet. The parents have two ways to make sure that the chick does not cause too much trouble while begging. They can leave immediately after providing food, which is what we’ve seen a lot of on Condor Cam; or they can discipline the unruly chick. This discipline can come in the form of the parent sitting or standing on the chick, or the parent may nip or tug at it. Either of these behaviors results in the chick being put in its place by the dominant bird in the nest, thus ending the undesired behavior. Sometimes, this discipline may occur before the chick acts up. Be mindful that this is perfectly normal for condors to do, even though it would be cruel for us to treat our own babies like that! When condors fledge, or leave the nest, they need to know how to interact with dominant birds at a feeding or roost site. This seemingly rough behavior from the parents will benefit the chick later when it encounters a big, unrelated bird that might not be as gentle.

There have been many questions regarding the chick being able to jump up on the nest box barrier. She hasn’t jumped up yet, but she may soon. Stay tuned for our next blog that will discuss this next big milestone!

Malayan Tigers, A Family Tradition at the San Diego Zoo

Having one offspring of a legendary pair is special. Having THREE is something else altogether. Mek and Paka, a breeding pair of Malayan tigers, are heroes in the fight against extinction. The latest in their long line of offspring, Cinta and Berani, are a pair of 18 month old sub-adult males that just sauntered into the Lost Forest at the San Diego Zoo. Cinta and Berani, aka “the Boys,” were born January 4th 2014 in a four-cub litter that also included two girls.

The addition of the youthful teenagers has been both joyful and a bit nerve-wracking! One particularly heart pounding moment came in the first few weeks of the boys exploring the recently renovated exhibit. At the end of May, Cinta and Berani were wading in the large pool in the lower exhibit when one decided to try to jump up the wall. Easily clearing 10 feet in a single bound, he gently fell back on his feet in the pool and wandered off to explore something else. Even though there was never a chance he could get out of the exhibit, it was still surprising to see how easily he leapt up a sheer wall. This was a true testament to how athletic and powerful these majestic creatures really are.

The exhibit was not the biggest adjustment the boys had to make. Their brother Conner, twice their age and a quarter larger in size, is an imposing and dominant male. Connor made it his mission to scent mark the entire exhibit thoroughly. This marking can last for a month. While the boys are never in the same exhibit as Connor, they know he is around and they had to adjust to seeing and smelling a much larger male. This certainly put the boys in a nervous state, leading to some funny interactions and behaviors early on. Both Berani and Cinta were on high alert the first day they and Connor were out on their exhibits for the first time. They could see Connor through the double fence and never once turned their backs on him the entire day. All the while, Connor just sat on his rock, welcoming the new kids to the block.

Once things settled down and all the tigers were getting comfortable with their surroundings, we all moved on to the next phase, exhibit swapping. Both Connor and the boys have now had time in each of the two sections of the redesigned tiger exhibit and they are noticeably calmer as a result. Connor, still a relatively young male himself, continues to show his youthful attitude and exuberance for life. On the first night of Nighttime Zoo, Connor decided to put on a show. He managed to create his own version of The Bellagio water show by ripping up a water line to his drinker. Water sprayed everywhere and one happy tiger got to play in it. The repairs were made the next day and after a short test, Cinta and Berani were swapped into the previously flooded exhibit. They decided to team up and proceeded to tear the water line out of the drinker, just after it got repaired! I guess the boys think imitation is the best form of flattery.

Just two months in with our rambunctious family of brothers, Connor, Cinta and Berani are all adjusting. The family fun and adventure shall continue!

A Little Switch

caption

A change of scenery will be enriching for active, curious Xiao Liwu.

On Friday our keepers decided to switch it up a bit for our panda bears (and for a particular tree); Xiao Liwu was moved into the first enclosure and Gao Gao moved to the “Keebler” side. This change of environment is nothing new to our bears (we do this every few months), and is a chance for guests and Panda Cam viewers to see some interesting behavior as the pandas get reacquainted with their new spot. Giant pandas are very good at scenting their territory, and when we are able to play “musical bears” we give them the chance to re-mark territory and exhibit some of those behaviors: scent marking in a handstand position as well as rubbing on trees and even on the ground. Not only is this fun for our guests to observe, it is a good behavior for our bears to express. Changing locations is a novel enrichment experience for the pandas.

The switch last week also gave our staff a chance to check out the little elm tree that Mr. Wu was exposing. For those of you who haven’t seen that particular enclosure over the years, it has gone through a few trees in its day. The first tree in the exhibit was knocked over by Su Lin, born in 2005. Luckily, nothing was damaged and we were able to secure her and the tree so that she could continue to use it as a climbing structure. We were then gifted with a young elm tree that Yun Zi (born 2009) tore apart during one of his many energy bursts. Shortly after that, we acquired the elm currently in the exhibit. We did our best to secure it so that the tree might stand a chance against a young, rowdy bear. So yesterday when our keepers discovered that little Mr. Wu had torn the plastic covering off the elm, they moved Gao Gao into the exhibit knowing that he probably wouldn’t destroy the tree.

Over the past ten years, I’ve watched cubs go through the many stages of adolescence, and they can be very destructive. The cubs learn how strong they are and like to test boundaries. And never forget how smart bears are and how curious they can be. As keepers, our job is to make sure that these bears go through these stages safely. For our researchers, this is a busy time watching and noting the many changes going on with our bears. This can often be fun for the observers as they watch the bears be a little silly and try out their abilities.

So while our staff does their best to restore the tree’s protective covering, enjoy watching the bears in a new—yet familiar—environment. Also keep an eye out for some smelling behaviors; after every storm I think we get some of the most fascinating behaviors from all of our animals as they investigate all the new smells kicked into the air.

Thunder and Lightning

The Zoo's newest giraffe calf, born May 5, seemed to get a real kick out of the thunder and rain last week.

The Zoo’s newest giraffe calf, born May 19, seemed to get a real kick out of the thunder and rain last week.

Here at the San Diego Zoo, our animals’ welfare is number one! If an animal appears to be having a difficult time, we will do out best to make sure that we can make them comfortable and figure out what may be the cause of any uneasiness. So with that being said, the storms that came through San Diego last week gave a few of our animals something new to say the least. On Tuesday, when the thunder began to move in, little Mr. Xiao Liwu decided that not only did he not like it, but that he wanted to seek shelter…inside!

Of course, animals in the wild are going to deal with this without the luxury of having a nice, climate controlled bedroom to run into. Since giant pandas are naturally found anywhere from 5,000 to 10,000 feet in elevation, they deal with a whole multitude of weather conditions including snow and extreme humidity. But our Mr. Wu has had a different life experience.

The day of the storm, I was also giving a tour around the Zoo and animals everywhere had their own responses to smelling the rain and hearing the thunder. A particularly special treat was watching our baby giraffe running around and kicking her legs out playing in the falling drops. I’ve always told guests that the best time to go to the Zoo or even the Safari Park is right before or after a storm. All the animals can smell the change in the air and it’s always fun to watch them.

Over the 10 years I’ve been working around the pandas, I’ve had the opportunity to witness interesting behavior and great moments with the bears. One of those is panda cubs in the rain, and the aftermath. All of our animals have shelter in their enclosure so that if it begins to rain hard, they can get out of the rain and still be visible to the public. Panda cubs have really never disappointed in their playtime in the mud. Just as human kids like to jump in puddles and make a mess, panda cubs love to slide, roll, and jump in puddles and mud. One of my favorite memories of Yun Zi (born 2009) was a morning I had put him in the “garden room” of Bai Yun’s indoor area so that I could clean the bedroom. It had rained a little and as I was finishing up, here came Yun Zi, dripping with mud. Total “boy” move; he had rolled in the mud and had clearly had a blast.

So, keep your eye peeled for those awesome moments, and again try a visit just before or after a storm. You’ll be amazed at what you see the animals doing!

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!

Gorilla Bachelors: A Day in the Life

Maka is the leader of the Zoo's gorilla bachelor troop.

Maka is the leader of the Zoo’s gorilla bachelor troop.

A typical day in the life of the San Diego Zoo’s bachelor brothers, 20-year-old Maka, 13-year-old Mandazzi, and 9-year-old Ekuba includes both some outdoor exhibit time and indoor bedroom time. On this sample day, they are scheduled to go outside in the morning, and our breeding troop will go out in the afternoon. After an early morning wake up to check on how everyone is feeling, a heart-healthy breakfast of low-starch biscuits and their favorite banana leaf browse, it’s time for keepers to head out to clean and set up the exhibit for the day. Keeping the boys active and engaged is a top priority; it’s one of the highlights of my day and most certainly theirs, too!

We have a wonderful and creative team of enrichment volunteers that keep our gorillas well-stocked with fun items like painted gourds, boxes, papier-maché and burlap bags, perfume-scented pine cones, bamboo cups for gelatin or peanut butter, palm husk baskets and comfy hay beds to sleep on (they even take special requests for birthday parties or upcoming holiday themes!)In addition to the enrichment, we also set out plenty of fresh cut browse. The boys get a total of 12 branches of a variety of browse delivered daily by our hard-working forage team. Willow, mulberry, and rusty-leaf fig are always a huge hit!  After we top off the exhibit with a liberal sprinkling of cereal to increase foraging, it’s time for the boys to head outside.

As is the case with all of our primates, the gorillas are part of an extensive training program that allows us to give them excellent medical care. On their way outside, each one of the boys stop in a chute and are asked for a variety of behaviors that allow us to get a good look at them one-on-one and address any issues. For example, we might notice Mandazzi has a hang nail and dry heels, so we file the nail and apply lotion to his feet; Ekuba needs a quick tooth brushing; and Maka has a minor cut on his arm that we will irrigate to promote faster healing. These are a just a few of the over 20 behaviors the gorillas know. This individual time keeps them in top form and develops an invaluable relationship of trust between gorilla and keeper. And it doesn’t hurt that they get yummy fruit and nut pieces hand fed to them during these daily check-ups!

Once outside, the boys enjoy their enrichment and foraging time, check in with a few devoted friends on the other side of the glass (our guests!) and settle in for a mid-morning nap next to the rushing sound of the waterfalls. Like all primates, gorillas like to eat throughout the day, so every couple of hours more food and treats are distributed by a keeper from the roof of the building. The boys each have their favorite “spot” to be in while the food is delivered. Maka usually prefers to hang back either on the “point” or along the side near the waterfalls to keep an eye on things. Ekuba takes the requisite spot between his big brothers, and Mandazzi, ever the foodie, likes to be front and center catching all of his food like a pro center fielder. In addition to fresh produce like yams, broccoli, snap peas, jicama. and green peppers, the boys get treats like peanut butter covered pine cones or Crystal Light-flavored ice treats. This enrichment requires a lot of time to enjoy, so they are occupied until their early afternoon naptime rolls around.

Keepers describe Mandazzi as a "foodie".

Keepers describe Mandazzi as a “foodie”; he’s also usually the first one into the bedrooms at the end of the day.

By mid-afternoon, when the bedrooms have been cleaned and the bedding re-fluffed, it’s time for the boys to come in so that our other troop can head outside. Mandazzi is almost always the first one in. His eager attitude has made him our star patient in training for voluntary cardiac ultrasounds. He has an appointment this afternoon and our veterinarian is already staging the scene. Heart disease is a major concern for adult male gorillas. To help with early identification and treatment of this disease, all four adult male gorillas at the Zoo are trained to allow us to “see” how their hearts are functioning.

Mandazzi comes up to the front of his room where the veterinarian and keeper are set up, positions himself with his chest flush against the mesh separating his space from ours, and an ultrasound probe is placed against his chest to capture images while a keeper gives him treats. Depending on the position and length of time we need him to hold the position, keepers offer the gorilla juice from a squirt bottle, applesauce from a spoon, or hand feed pieces of fruit and nuts. Mandazzi did great and three different angles of his heart were recorded today. He gets a few more treats from a happy veterinarian and then it’s time for second lunch and more fun enrichment!

While inside, the gorillas often get very messy enrichment. There are piles of shredded paper or pine shaving with raisins to dig through. Magazines are sprinkled with seeds and spices and ready to be torn up. Often, their produce and hay is fed out in puzzle feeders that take time to manipulate. With a nature DVD playing on their wall-mounted flat screen TVs and a pile of cardboard boxes to dig through, the boys are busy right up until late afternoon nap time. After a power nap, the boys get another round of browse to strip and eat while the day keeper finishes her/his tasks and updates the evening keeper that takes over the area. As the sun sets, the boys get ready for their evening routine— and more food!

Each of the boys has their own room at night. They are fed in their separate rooms to make sure everyone gets their fair share. Afterwards, the doors between rooms are opened wide enough for little, peacekeeping Ekuba to mingle. This allows for some socializing but still gives both of the big boys a peaceful night’s sleep without worrying about the other sneaking into “their” room while they are relaxing. Maka is the troop leader, being the oldest brother, but Mandazzi already outweighs him and we are always aware of the possibility of a coup. No such drama tonight, however. All is quiet as bedding is adjusted and sleepy boys are ready to settle in for the night. After all, tomorrow starts with an early morning keeper wake up call, and big bowl of heart healthy biscuits.
