Queen Nan is the oldest polar bear in the USA

Nan (and friend) in the Toledo Zoo, 2014

 Nanuyaak is her official name, but we all just call her Nan. At age 30, Nan is the oldest polar bear in the US zoo system. She started off life in the wilds of Alaska, and was rescued as an orphan on May 1, 1995, spending a few days in the Alaska Zoo.

The little orphan girl Nan lived and grew up for six years in the Point Defiance Zoo in Tacoma Washington. In 1996 two more orphans, from Churchill in Canada, arrived in Tacoma. The boys Blizzard and Glacier were a year younger than Nan. I imagine that Nan, Blizzard and Glacier were playmates, since they were close in age.

Point Defiance has been home to a good number of polar bears over the years. Blizzard and Glacier remained at Point Defiance until they died, Glacier in 2015, and Blizzard in 2023. 

Nan moved in 2001 to Toledo to join young Crystal at the brand new Arctic Encounter. Crystal had arrived from Belgium the year before. A young male named Marty had arrived in Toledo from Brookfield Zoo in 1999. Marty was two years younger than Nan. This trio of young bears started a tradition of having polar bear cubs in Toledo.

In the fall of 2006, both lady bears gave birth to Marty's cubs. Nan had a son Nikita born November 21, and Crystal gave birth to twin daughters, Aurora and Anana, on November 25.

Things were fine while the moms were in their maternity dens, but when the cubs were old enough to make their debuts, things got crowded, with rotating the two young families, and also Marty, through the one public enclosure. They do have separate enclosures in the back, but it was thought best that Marty should leave for awhile, moving to Pittsburgh for over a year. Then in a swap at the end of 2008 Marty returned to Toledo, and twins Aurora and Anana moved to Pittsburgh, where they stayed for a year until their brand new home in Columbus was ready. 

Nikita stayed in Toledo until he was a little over three years old, then moved to the Kansas City Zoo. Later he moved to the North Carolina Zoo, and is now in Hogle Zoo in Salt Lake City with Crystal's granddaughter Neva.

While Marty and Crystal went on to have more cubs, Nikita was Nan's only offspring.

Nan stayed in Toledo until 2017, when she moved to Brookfield Zoo in Chicago, to be companion to Marty's brother Hudson. In 2021, Nan moved to Como Zoo in St. Paul, where old Neil was alone after the death of his twin brother Buzz in August of 2020.

Nan has settled in well at Como, and it has done Neil a world of good to have her as a companion.

In 2022, young Kulu arrived from Columbus. Kulu was two years old, the son of Crystal's daughter Aurora. It was likw the story of "The Three Bears," and everything was just right for Grandpa Neil, Grandma Nan and young Kulu.

In those days, Neil played with Kulu quite a bit then, but has slowed down in the past couple of years, and now Nan is the primary playmate for Kulu.

Kulu tries to boss Nan. It doesn't work. Nan is in charge.

This year the Como Zoo planted a field of wildflowers in one of the enclosures, to make a gorgeous natural habitat for the polar bears, and they love it. 

Again, Kulu tries to challenge Nan, in the wildflowers.
 She doesn't back down and Kulu runs away.

Currently, the oldest polar bear in a zoo worldwide is Antonia, who is a dwarf polar bear, something unique in all the world. Antonia is 35 years old and lives in Gelsenkirchen ZOOM in Germany. She was born in Karlsruhe of normal sized parents. 

Antonia of Gelsenkirchen ZOOM is 35 years of age.

Nan is quite active, and has no problem climbing up the polar bear shaped Pride Rock, chasing young Kulu when he gets out of line, and roaming in the meadow. Sometimes she swims with Kulu too.

Kulu and Nan have a swim.

And swim some more.

As for the other older bears in the US, Nan's companion Neil is the oldest male in the US and actually in the world, born December 9, 1995, in Louisville, and at 29 years old, is the same age as wildborn female Chinook in San Diego (birthday unknown). Female Snowflake of the Pittsburgh Zoo is a few weeks older than Neil at 29. Snowflake was born November 28, 1995, in Buffalo.

Male Kiska of ABQ Biopark, is 28 years old. He and his late twin brother Koluk were born November 19, 1996, in Hogle Zoo in Salt Lake City.  Anoki of the Seneca Park Zoo in Rochester NY was born November 20, 1996 so is 28 years old, one day younger than Kiska.

Como Zoo in St. Paul Minnesota is home to three polar bears, two of whom are age related record holders. While Nan is the oldest female polar bear in the US, Neil is the oldest male polar bear in human care.

Neil, named for astronaut Neil Armstrong, and his twin brother Buzz (the namesake of Buzz Aldrin), were born in the Louisville Zoo on December 9, 1995.  Their father was Irsinaki. Their mother Skeena was half sister of Arki (mother of Marty). Neil and Buzz had an older brother, Icee, who lived at the Cincinnati Zoo where he fathered twins Berlin (who later lived with Neil and Buzz) and Yukon (father of Lee and others). Neil and Buzz's older sister Ulu became the mother of Berit of the Cincinnati Zoo, now living in Henry Vilas. Irsinaki and Skeena were also the parents of triplets born in the Louisville Zoo in 1992, one of these triplets was Aquila.

Neil and Buzz moved to San Diego in 1997, and lived there for five years, before moving to Como Zoo in 2001.

Because of planned renovations at Como, the twins lived in Detroit for two years from 2008 to 2010, where they played with young Talini, Barle's cub. They then returned to Como, where they lived happily together at their Polar Bear Odyssey until Buzz died in 2020.

During that time, they played host to three grizzly bears in 2011 whose zoo home in Minot, North Dakota Zoo was flooded out, until their enclosure could be rebuilt.

Then they welcomed their older niece Berlin, whose enclosure at the Duluth Zoo was consumed by a river flood in 2012. She stayed for six months, and enjoyed bossing around her younger uncles before moving to the Kansas City Zoo, where she lived well into old age.

In 2014, those crazy two year old twins Suka and Sakari moved in from Toledo, waiting for their new home at Henry Vilas to be completed. The young twins stayed for seven months! Their father Marty was nephew of Neil and Buzz's mom Skeena.

Neil and Buzz - 2016

After that, Neil and Buzz closed their Bear B&B and it was just the brothers together until Buzz passed away in 2020. Neil struggled being alone, so older lady Nan came to Como Zoo in 2021. A few months later, two year old Kulu arrived from the Columbus Zoo. Kulu is the son of Crystal and Marty's daughter Aurora, and Yukon's son Lee.

Neil's food is ground up and put in a paper cup.

Neil is related to Kulu through both his mother and his father. Neil's brother Icee was father of Yukon, grandfather of Lee, and great grandfather of Kulu. Neil's mother Skeena was sister of Arki, who was mother of Marty, grandmother of Aurora, and great grandmother of Kulu.

Neil and Kulu playing in 2022, back when Neil felt better.

Nan, being wildborn, is not related to Kulu or Neil, but she did live for many years in Toledo with Crystal, who is Kulu's grandmother.

Polar Bear Odyssey has a great set up for polar bears. Since 2010, the bears have enjoyed two lovely enclosures of 13,140 square feet outdoor space with saltwater pools and grass and shrubbery, and a central training area. Their favorite side is the right, with the 16 foot deep diving pool, sometimes stocked with live fish. But the left side, with the shallower pool that Neil favors, is where the snacks are placed for the daily keeper talk, and this year, this enclosure has turned into a wildflower meadow, towered over by a polar bear shaped jutting rock. There is also a digging pit, so that's fun too.

Neil, at age 29, has lost most of his teeth, which is why his mouth seems to be foaming when he eats, and often drools. His keepers mash up his food to help him out. Neil weighs 1000 pounds, now, which is a little less than when he was in his prime, but the lighter weight is easier on his bones, so the keepers try to keep it about there. 

Neil in the wildflowers - July 2025

Nan weighs 650 pounds. Kulu weighs 1300 pounds.

Neil has arthritis, which makes it hard to get in and out of even the shallow pool, which is why he looks so dirty. Still, he does manage a bath every few weeks. I did see him wander out into the wildflowers, and he even attempted to climb the polar bear rock.

Neil by the shallow pool - July 2025

When Kulu first arrived in 2021, Neil would often play with the youngster. But Neil is slowing down. Kulu still wants him to play, but most of the time Neil just can't. So Kulu plays with grandma Nan, who is happy to spend time with the young bear. 

During the keeper talk, Keeper Allison pointed out that in the wild, a bear like Neil would be lucky to live to be 15.

Neil and the other bears are trained to take part in their own medical check ups, and a specially designed "sleeve" even allows blood to be drawn, a technique that Neil helped to test out and pioneer in its usage some years ago.

Kulu asks Neil to come play in the water. Neil is too tired.

Handsome Neil. Hang in there, big boy.

Kap leaves a legacy

Kap, always curious

 

Kap was a handsome bear

Kap was born in the Moscow Zoo on October 16, 2000. He had many relatives, including some half brothers. He leaves behind a daughter, Anouk now in France, and a son, young Mika, still living with his mother Nuka in Karlsruhe.

Kap's father was Uold, brother of the famous Uslada, mother of 16 cubs, and also of Maleishka, mother of new father Pim in Sao Paulo.

Kap's mother was Murma, who was also mother of  new father Gota of Japan (father of the late Milk and also 4 year old Fubuki),  Boris/Ivan of Skandinavisk Dyrepark in Denmark (father of Nuna's cubs), and  Rasputin of Aalborg (father of Hope and the triplets Tala, Indie and Yuma). 

Kap in his empire. My photos from 2017.

He lived in Karlsruhe three times, and Neumünster twice. He also live in Hannover for a short time. While in Hamburg, he became a father of daughter Anouk, born in 2022 to Viktoria. Then just last fall, his mate in Karlsruhe, Nuka, gave birth to twins, one of whom survived and is a boy named Mika. Kap spent many years alone in Neumünster, so I was glad when he was given the chance to live with another bear, and to father some cubs.  

In Karlsruhe, Kap had a nice big pool, with an underwater viewing area.

Kap - King of the Mountain.

Kap and the cave

Kap rather suddenly became ill about two months ago, and the vets examined him under anesthesia to find the cause, and it seems there were a number of illnesses. He would get a little better, then worse again. At the end, he could barely walk and had trouble lifting his head. He was confined to the mother-cub enclosure, which was a lot smaller and safer for him in his condition.

Smiling Kap

It became clear that his condition had deteriorated to the point when the kind thing was to put him to sleep. At age 24, he was the oldest male polar bear in a European zoo. Worldwide, the oldest in Neil in Como Zoo, who is 29 years old. In the wild, a polar bear would be lucky to live to be 15 years of age.

Sharing his lunch with the herons

Kap and feathered friend

Kap was a gentle bear, always curious. He was happy to share his food with the herons who liked to visit the polar bears in Karlsruhe. 

It's a sad time in Karlsruhe. Kap was well loved. 

Kap in his swimming days

The zoo published this on their facebook page, to announce the death of Kap.

At 24 years old, he was the oldest male polar bear in the European Conservation Breeding Program (EEP). However, after his health deteriorated further, Kap was euthanized today at the Karlsruhe Zoo. The two zootists and two external veterinarians had previously placed the polar bear in anesthesia for further examination.

Kap has been strangely worse in the past few days. Among the previous complaints, he had had trouble walking, and also kept his head very low in a kind of good posture. That's why the polar bear was put on pain medication. Zoo doctors Dr. Marco Roller and Dr. Lukas Reese opted for another examination in anesthesia.

During this, it was found that liver levels had deteriorated despite special medication. In addition, the study, conducted in collaboration with AniCura Karlsruhe, showed major changes in the gallbladder and liver in the ultrasound. Since there was no positive prognosis, it was decided to redeem Kap. The body of the animal will now be examined in pathology. "A section is generally made for such zooters, we hope for even more clarity from it. Unfortunately, on living large animals, the possibilities for examination are limited, so pathology always has a special importance for us," says Roller.

About eight weeks ago, it had begun that the general state of  Kap changed from one day to the next and the responsible concern was prepared. The polar bear's health has become increasingly critical. Subsequently, he was already examined under anesthesia. However, the investigation at that time did not bring a clear conclusion to the cause. Meanwhile, Kap was also getting better, which gave the zoo team hope. The situation had to be re-evaluated due to the problems that have now been added.

Farewell, handsome Kap.
