The last days of Koluk

 

Koluk two weeks ago

When visitors enter ABQ Biopark in Albuquerque, New Mexico, the first thing they see is a huge marquee photo of polar bear brothers Kiska and Koluk above the entrance gate.

Above the ticket taking booths at ABQ Zoo, the polar bears greet you.
Now news has come that one of those gorgeous bears, Koluk, has passed away.

When I visited ABQ Biopark in Albuquerque two weeks ago, I couldn't guess that one of the twin brother bears I had come to see would be gone so soon.

I had planned to wrote a piece on my visit to the bear brothers in the desert, and I still will do that, but sadly, I must write a farewell to Koluk, the most handsome of polar bears. 

Kiska is front, Koluk in back

Koluk and Kiska were born in Salt Lake City in November of 1996, so they were both getting up there in years, but both of them looked pretty hefty and healthy for male bears of 26 years. However, I could tell that something was up with Koluk, for his fur, usually green with algae from all his swimming, was white. He hadn't been in the water for quite awhile. His movements were slower. He kept to himself. He was just not his fun-loving self.


Koluk's fur was white, not its usual algae green.

 Koluk spent much more time behind the scenes than his twin brother. While Kiska was out and about and having fun, Koluk had hidden himself away much of the time. Even when the keeper threw the special daily treat of Rainbow Trout into the water, Koluk didn't want to wade in to retrieve it. But wade in he did, with a complaining look, and got the fish.


Koluk did wade in a bit to get the rainbow trout.

Koluk then retreated onto dry land to shake off and eat his prize.

Koluk, always the swimmer, would rather remain on shore during his final weeks. Kiska still dives right in.

I spent four days at the zoo, and on Monday, May 15, I waved goodbye to the the polar bear brothers, wondering if this would be the last time I would see Koluk, for I suspected he wasn't well.

I told the keeper, whom I had met last year, that I was worried about Koluk. He had slowed down so much, was staying out of sight mostly, and hadn't been in the water at all, which was not like him. She said that Koluk had shown some behavior changes for the past couple of weeks, but the changes were pretty recent and hopefully he should  get back to normal and be fine.

But on Friday, May 19, Koluk underwent an examination while under anesthesia, and the vets found that he had advanced liver and kidney failure. During the next week, they did what they could, but his health declined faster than expected, and he was released from this life on Friday, May 26.

He and his twin brother came from the Hogle Zoo in Salt Lake City to Albuquerque when they were just ten months old, so they have lived in the zoo in the desert for a quarter of a century.

Their mother was Chinook, descended from Bruno and Hilda of the Memphis Zoo, and as such they are related to a good number of European bears descended from CW, daughter of Bruno, her daughter Ilka, and Freedom, her granddaughter. Kiska and Koluk's father was Andy, descended from Becky and Herman Jr. of the Buffalo Zoo. 

 The ABQ Biopark Zoo (then the Rio Grande Zoo) enclosure was new when they came, has a lower pool and upper pool, as well as a waterfall and slide, which the bears would sometimes climb up.


Koluk in the water, as was his usual habit, last summer.

In their early days in ABQ, their young niece Anoki, daughter of their sister Aurora, came to live with them for awhile too. She is now living in Rochester NY, where she was born.

Koluk and Kiska were brothers of the late Anana of Buffalo, Brookfield, Cincinnati and Detroit, and half brothers of the late Aurora, and also Denali who lives in Japan and is father of eight cubs there. They were uncles of Luna of the Buffalo Zoo (daughter of Anana), and also Lee, Anoki, Peyton and Haley, children of Aurora.

Koluk was a handsome bear, with a magnificent head. He was chosen by Joel Sartore for his photographic Animal Ark, featured in National Geographic. 

He was playful all his life, and even sometimes threw balls and other toys over the fence to the visitors.

 He was always one to have fun with his toys.


In 2019 he was diagnosed with a heart murmur. After that, when it was fish throwing time, the keepers would invite Kiska to do his cliff dive, but Koluk was restricted to getting his fish at ground level.

 

The last photo I took of Koluk (in back) on May 15. Eleven days later he was gone. Right after the fish throw, Koluk retreated into the bedroom area, all worn out. That's Kiska in front, ready for more adventures.


Kiska and Koluk are much like that other pair of twin brothers, Neil and Buzz in Como Zoo in St. Paul Minnesota, about a year older than Kiska and Koluk, together all their lives. When Buzz died a few years ago, Neil was alone, but before too long, an older lady bear named Nan moved in, and then three year old Kulu came along, and Neil was not alone any longer. Maybe a companion can be found for Kiska. If not, Kiska will be just fine on his own.

During my four days at the zoo, I noticed that Kiska had, in a sense, already moved on and was behaving independently. He did take note of his brother, and they spent some time together, mostly in the front cave area in the morning, eating breakfast together, enjoying the polar bear chow spread out for them with extra fruits and vegetables.  But Kiska spent his days in fun activities, tossing and destroying a barrel, swimming in the deep pool, doing his seven step pacing dance on the ledge (although not as much as he used to). Koluk sometimes came out to watch, but mostly stayed inside.

The polar bear brothers have been a big part of the ABQ Biopark Zoo for a quarter century, and Koluk will surely be missed by his many fans and friends, and especially by his keepers, who loved him dearly. 

Rest in Peace, big guy.

Update: Anana's death was from natural causes

Anana in Brookfield Zoo, Chicago


The news of the tragic death of Anana at the Detroit Zoo on February 8, just a little over two months ago was all the more heartbreaking to think that another much loved bear, Nuka, had killed her during attempted breeding. Anana was adored by zoo visitors from the Brookfield Zoo, Buffalo Zoo, Cincinnati Zoo, and her final home at the Detroit Zoo.

It is a relief to know the truth now, with news of the results of the autopsy.

An independent commission of experts has studied what led to Anana's death, and their results were shared this week with Detroit Zoo members through an email. 


Anana in Cincinnati



The following was sent out in an email to the Detroit Zoo members this week from the Detroit Zoological Society.

DZS recently completed an in-depth review into Anana’s death and, working with veterinary pathologists at Michigan State University, discovered that she died from advanced heart disease. She was not killed by male polar bear Nuka, as was originally believed. The DZS’s Animal Health External Review Panel, a group of experts in veterinary and human health, endorsed this conclusion.
Analysis of Anana’s heart tissues showed that she experienced acute heart failure or a fatal arrhythmia before or during breeding attempts. It was impossible to know that she had a cardiac condition called multifocal myocardial fibrosis, as she showed no clinical signs and a 2020 medical examination noted no abnormalities in her heart function. Wounds on Anana likely resulted from Nuka holding her with his teeth, as is typical during polar bear breeding. He was also observed moving her around the habitat after she became unresponsive, possibly because he was confused by her behavior.
While DZS continues to mourn Anana’s loss, the polar bear staff is focused on caring for Nuka, as well as female Suka and her 6-month-old cubs. Laerke (the cub being reared by staff) is living in the polar bears’ building, but is separated from the other bears while she gets to know them from a distance. Suka and Astra (the cub she is raising in the maternity den) will soon be exploring the Arctic Ring of Life’s Tundra habitat.

Anana


From the start, Nuka was presumed guilty, but now has been found innocent of causing Anana's death. It sounds like the wounds were inflicted upon her face and neck by Nuka's efforts to wake Anana up after her heart failure.

Nuka is the father of the Suka's twins and we will be able to see these cubs, one raised by their mother Suka and the other by keepers, in the coming weeks at the Detroit Zoo.  A shadow over the happy events surrounding the new cubs has been lifted with the news that Anana's death was from natural causes. 

Anana was born at Hogle Zoo in Salt Lake City on December 12, 2000. The petite lady bear, weighing in at only 450 pounds, had one daughter, 8 year old Luna, now living in the Buffalo Zoo with Suka's brother Sakari. Anana died of heart failure in Detroit on February 8, 2021.

Tragedy in Detroit

 

Anana

Update on April 25, 2021: The cause of Anana's death has been announced. She died of heart failure. The wounds on her head were probably from Nuka trying to move her around the area, maybe nudge her back to life.


Today is a very sad day. Our beloved Anana, age 20, was killed today, Monday, February 8, 2021, by 16 year old Nuka in the Detroit Zoo.  They had lived together last year in peace, and had just been reunited last week when Anana emerged after denning up. 

The male, Nuka, has been with several females over the years, without incident. The other female polar bear at the zoo, Suka, gave birth to twins in November and is behind the scenes. 


Anana in Cincinnati

Anana was born December 12, 2000 in Hogle Zoo in Salt Lake City to Chinook and Andy. She went to the Buffalo Zoo when she was two, and lived there until 2013, shortly after she gave birth to Luna, who still lives in Buffalo. Luna's father was the late wildborn Nanuq. Anana took no interest in the cub, so Luna was raised by keepers. Anana moved almost immediately to Chicago. 

Anana in Brookfield Zoo

Anana stayed for several years in Brookfield Zoo in Chicago, where she lived with old Aussie, and with his son Hudson. Then she returned to Buffalo for a year after the Buffalo Zoo completed construction of a beautiful new and spacious polar bear habitat, to replace the antiquated bear pits Anana knew before.

Anana was a very pretty, round fluffy bear

She spent several years in the Cincinnati Zoo, where she initially rejected Little One, but then changed her mind and they got along well, although no cubs resulted. 


Anana, right after she arrived in Cincinnati

While she was in Cincinnati, I went to see her quite a bit, and she was a real favorite with zoo visitors. She was petite, just about 450 pounds, and very round and fluffy, with a cute pouty lower lip. She was playful and fun, and loved to pose for the visitors.


Anana, eating, while Little One adores

She brought out the best in Little One. He was active and playful again, in spite of his advanced years. They seemed to really enjoy each others' company, once Anana got over her original reluctance.


Anana at Halloween. There's that cute lower lip.

Anana would take awhile to warm up to a new male companion. In Buffalo, she didn't want Nanuq at first, but after a year, she decided she liked him after all, and the result was Luna. The same thing happened in Cincinnati. She and Little One would huff and puff at each other, and avoid getting close for the longest time, and then all of a sudden, she couldn't get enough of him.  

Maybe that is what happened in Detroit, but Nuka was impatient and didn't want to play her games. We don't know what happened and maybe never will.


A year ago she moved from Cincinnati to Detroit, and it was hoped that she might have another cub with Nuka.

It is rare for polar bear mating to to lead to a death, but it does sometimes happen with these predators. A similar tragedy happened in Russia last spring, A polar bear named Aurora moved from the Royev Ruchey Zoo in Krasnoyarsk to Izhevsk Zoo in March. She was introduced to the male Baloo, all seemed to be going well. Then Baloo attacked suddenly and killed Aurora, on April 29, 2020.

Anana's sudden tragic death comes as a great shock to me. I knew her so well, and she had a big personality in such a tiny bear body. And now she is gone. I was hoping to see her again this spring when I go to Detroit to see Suka's cubs. I miss her already.

Besides her daughter Luna, she also had twin brothers, Kiska and Koluk, who live in Arizona, and a brother, Denali, who lives in Sapporo Japan.





Rest in Peace, beautiful girl.

Auntie Hope and her niece Nora

Hope is up, Nora is down, headed to the pool.


As we bid adieu to 2018, my last little story of the year is the tale of my visit to two little cubs I knew separately when they were small, but are now living together, growing up as playmates.

Hope and Nora at play in Salt Lake City

I visited polar bear cubs Hope and Nora in Salt Lake City in October to check up on these girls that I had known as young cubs and were now almost three years old. I am so glad these girls are together. Neither one had another cub to play with when she was younger. Now they have been together for over a year, and the keepers say they have become good friends.

Hope and her mother Crystal
Hope was born in Toledo to Crystal and Marty on December 3, 2015 in Toledo Ohio.


Nora in Columbus
Nora was born to Crystal and Marty's daughter Aurora about a month previous in nearby Columbus Ohio.

 Nora's father was wildborn Nanuq, who has since died, but not before he fathered three more cubs in Columbus. The name Nora is a combination of parents' names, Aur0ra and Nanuq.


Hope in Toledo
These two cubs, Hope and Nora, were the only cubs born in the U.S. zoos in 2015. There were three cubs born in 2016, to Aurora and her sister Anana, with Nanuq as the father, in Columbus, but there have been no surviving cubs in 2017 or 2018 born in US zoos. 


Nora in Columbus
While Hope was raised in Toledo by her mother, just a few hours away in Columbus Ohio, Aurora took care of Nora for the first few days, but then spent longer and longer periods away from the newborn, so the keepers took over and raised Nora by hand, sharing many photos and videos of the wee one as she was growing up behind the scenes. Nora became an internet phenomenon.


Baby Nora
Back in the Spring of 2016, when Nora was introduced to the public at the Columbus Zoo, she was only on view in the big enclosure for an hour every morning, starting at 9:30 a.m. There were long lines of Nora fans every morning, waiting for the chance to see her run and jump and swim and chase the fish for that precious hour, with docents on hand to hurry people along to make room for others.  Then at 10:30 a.m., Nora went behind the scenes for the rest of the day and the big bears came out. Her fans could shop for special Nora t-shirts and other merchandise, but Nora was hidden for the rest of the day. Nora was a big hit with the public, but hard to see because of the short timeframe.


Nora after her debut in Columbus
The public wasn't told, and this may explain why her mother wasn't taking proper care of her, but when Nora was about seven weeks old, she was diagnosed with metabolic bone disease cause by an imbalance of calcium, Vitamin D and other nutrients. The young cub received supplements right away, and seemed to be doing well, but she does have joint disorders which make her have a different gait, and maybe a limp or waddle. It may cause arthritis in later life. She will continue to get special care because of this.


The late Nanuq, in the center, with twin sisters Aurora and Anana
Because Nora was only in public view for an hour every day, that meant her mother Aurora and Aunt Anana could spend the rest of the day in the big enclosure with big handsome old guy Nanuq. More cubs could be expected in the 'Winter of 2016-2017, so Nora was sent to the Portland Zoo to live with old lady bear Tasul. Sadly, Tasul died a few months after Nora arrived, so once again, she was alone with her toys. Fortunately, Nora was always very good at entertaining herself.

Nora in Columbus
Nora lived in Portland about a year, and was doing well, but to provide her with company, she was moved to Utah's Hogle Zoo in Salt Lake City in September of 2017.  About the same time, two year old Hope moved from Toledo to join her niece in Salt Lake City. The two cubs hit it off very well, and each has enjoyed having a playmate of the same age.

Nora in her favorite spot in the Hogle Zoo pool


Because the pool in Hogle Zoo is filled with salt water, and the cubs splash a lot, the windows by the pool are always dreadfully spotty, making it hard to get good clear photos. And almost all of the windows are over water.

When the girls arrived in Salt Lake City, Hope was 100 pounds heavier than Nora. Now, a year later, their weights have evened out. In November, the time of Nora's party, Hope weighed in at 593 pounds, and Nora was up to 571 pounds.


Hope charges after Nora, wanting to play

How do you tell the girls apart? They are about the same size now, but they have differently shaped bodies. Nora is rounder, and Hope is more streamlined. Nora has a square snout, and Hope has a longer pointed snout.


Hope has the pointy nose

Keepers say that Nora is more people oriented, which is only natural because she was raised by her keepers, and looks to humans. 

Nora

The best way to tell them apart is by their activities and where they choose to spend their time.

Nora

Nora is very interested in the fish given to her neighbors, the seals and sea lions. Maybe she got a taste for the live fish in her pool in Columbus. Maybe her joints feel better when she is floating in the water.

There is also a window in the divider between the bears and the seals, above the water level, and Nora will sometimes jump up and put her paws on the ledge so she can peek over for a second into the Sea Lions' home.

Nora pulls herself up to get a better view

Hope has rolled in the mulch and gotten dirty,
 walking along the top of the wall. Nora is in the water.
Sometimes Nora gets out of the water to go up and play with Hope. Soon, however, she is back in the water, stalking the seals.
Hope on the wall, Nora on the ground
Hope, on the other hand, is a land lover. She traverses along the top ridge of the enclosure, back and forth, then jumps into the water to play for a minute or two with Nora, then back out again, often rolling in the mulch to become a brown bear. When she is in the water, she tries to go through the underwater tunnels.
Hope and Nora together in the water, for a minute or two. It doesn't last long.


 The zoo put on a birthday party for Nora with the theme Rainbows and Unicorns on November 6. It is on the zoo's facebook page so you can watch the girls party. The link is posted below. Of course Hope got some treats too. Then in December, there was another party for Hope as she turned three years old.

Hope


Nora is a water baby, which is great because water therapy helps with her bone and joint development. She spends a lot of her time floating in a particular spot, where she can keep her eye on the underwater window between the polar bear pool and the Sea Lions and Seals. Occasionally she will attack.

The Hogle Zoo threw a little birthday bash for Nora with special treats. Here are a few photos I took from my computer. To see the entire party, click on this link for the video of Nora's birthday party:
