We now have 20 zoos holding 40 polar bears - 21 females and 19 males (updated).Sad losses
33 year old Berlin, the oldest US zoo polar bear at the time of her death, died January 11, 2023 in the Kansas City Zoo. She and her twin brother the late Yukon were born in 1989 in the Cincinnati Zoo. She lived much of her life in the Lake Superior Zoo in Duluth Minnesota until it was flooded in 2012. She escaped but was recovered and spent some time in the Como Zoo before going to Kansas City.

15 year old Anana, daughter of Crystal and the late Marty, and twin sister of Aurora, died in the Columbus Zoo October 12, 2022. She had been born in Toledo, and was the mother of Amelia Gray. |

Blizzard, a wildborn rescued cub, died at age 26 in May of 2022, at the Point Defiance Zoo in Tacoma Washington, after a battle with cancer. He shared much of his life with Boris, the rescued circus bear. |
Marty of the Toledo Zoo |
Marty, father and grandfather of almost all the younger generation of bears, died in the Toledo Zoo on November 4, 2021, just short of his 25th birthday. He had been born in the Brookfield Zoo.

Snow Lily in 2013 at the Milwaukee County Zoo. |
37 year old Snow Lily died September 24, 2021, at the Milwaukee County Zoo. She was the oldest of our bears at the time. The Milwaukee County Zoo now has no polar bears.
 |
Anana, front, died in February of 2021 at the Detroit Zoo. Little One, behind Anana, died a month later in Cincinnati. |
Anana, born in Salt Lake City, died February 8, 2021, in another tragic loss. Luna's mother Anana had moved from Cincinnati to Detroit in early 2020, and on February 8, 2021, was found dead of heart failure. She was so young at just 20 years. At first it was thought that gentle Nuka was responsible, for Anana had some bloody wounds around her head and neck, but an autopsy confirmed that the wounds were superficial, and Nuka was just trying to awaken his dead princess.
Little One died March 21, 2021, at age 31 the oldest male polar bear at the time. The Cincinnati Zoo now has no polar bears. The area is being rebuilt as a North American habitat with black bears expected to be in residence.

Buzz in Como Zoo, 2016. |
Buzz, twin brother of Neil, died at the age of 24 in August of 2020 at Como Zoo in St. Paul Minnesota. Brother Neil still lives at Como, now with two other bears. The twin brothers were born in the Louisville Zoo December 9, 1995.

Blizzard and Boris at Point Defiance Zoo in 2018 |
Boris, the rescued circus bear and last survivor of the Suarez Six, died in September of 2020 in the Point Defiance Zoo in Tacoma Washington. Boris had been born in Rostock, Germany. Despite his many years of suffering in the Mexican circus, he lived to the ripe old age of 34.
Moving around
Maryland has sent its two young girls to other zoos, and the grizzly bears have taken over the polar bear habitat at the Maryland Zoo. They no longer have polar bears. Amelia Gray has moved to Portland where she now lives with her sister/cousin Nora, previously of Salt Lake City. Neva moved from the Maryland Zoo to Salt Lake City, where she now lives with Nikita.
Hope, who lived in Salt Lake City with niece Nora, was moved to Brookfield Zoo in Chicago, where she now lives with Hudson.
Nikita moved from the North Carolina Zoo to the Hogle Zoo in Salt Lake City. Payton moved from the Memphis Zoo to take his place in North Carolina.
Nuniq moved from the Henry Vilas Zoo to the Kansas City Zoo. Bo, growing up, moved from the Toledo Zoo to the Henry Vilas Zoo to be with Berit.
Kulu left his mom Aurora in Columbus and moved to the Como Zoo in St. Paul Minnesota, where he lives with the two oldest bears, Nan and Neil.
Fewer zoos with polar bears
The Henry Doorly Zoo in Omaha, Nebraska gave up its great history of polar bear keeping several years ago, sending elderly Bam Bam to Kansas City, where she later died. There are now no polar bears in Omaha.
The Maryland Zoo has given up polar bear keeping, with the departure of Amelia Gray and Neva.
With the death of Little One, there are no more polar bears at the Cincinnati Zoo. The Bear Hill area is being remade into a North American Habitat.
With the death of Snow Lily, the Milwaukee County Zoo has no polar bears.
Not that many years ago, there were polar bears in San Francisco, Denver, Cleveland, Indianapolis, Philadelphia, SeaWorld San Diego, Tucson, Providence RI, Worcester MA, Bronx Zoo and more. Now habitats are greatly improved, but there are fewer of them. Some zoos in the past might have had eight or more polar bears; now a zoo is lucky to have just one.
New habitats
In positive news, the Oregon Zoo in Portland has reopened its newly refurbished polar bear area, and Amelia Gray of the Maryland Zoo has joined her sister/cousin Nora there. Both girls were born in Columbus.
The Point Defiance Zoo in Tacoma Washington, lost old Boris and then Blizzard, and the polar bear area was empty, but the news is that they are rebuilding a better polar bear habitat and plan to welcome new residents this year.
Some Statistics
Of the 19 living males, only two have fathered cubs: Lee is father of Kulu, and has just rejoined Aurora in Columbus in time for breeding season. Nuka is father of Astra and Laerke in Detroit, and spent the last year in Toledo, where he fathered another set of twins with Crystal. He has just left Toledo, and although his destination was not announced, the plan always was to bring Nuka back to Detroit.
Three males, Kiska, Koluk and Neil, had been neutered many years ago.
Of the 21 living females, four have given birth: Nan (who is too old now), Crystal, and Crystal's daughters Aurora and Suka.
Eight polar bear cubs have been raised by keepers to some degree: Luna of the Buffalo Zoo (rejected by her mother Anana), Kali of the St. Louis Zoo (orphaned cub rescued in Alaska), Qannik of the Louisville Zoo (rescued cub in Alaska), Nora of the Portland Zoo (mother Aurora neglected her), and Laerke of the Detroit Zoo (mother Suka raised one cub, but smaller cub was failing, needed medical help). Twins Tatqiq and Kalluk, and Chinook, all three of San Diego, were rescued in the wilds of Canada as cubs.
In addition, the newly arrived unnamed male yearling at the Alaska Zoo is being raised by keepers.
Seven of our US zoo bears were born in the wilds of Canada or Alaska: Nan of Como, the three bears in San Diego (Chinook, Tatqiq and Kalluk), Qannik of Louisville, Kali of St. Louis, and the new unnamed rescued cub at the Alaska Zoo. Qannik, Kali and the new cub, as property of the Department of Fish and Wildlife, cannot be part of the breeding program.
Supermom Crystal is the only polar bear we have who was born overseas, specifically Belgium. Currently, it is not permitted to import polar bears from other countries. Crystal's sister Blanche still lives in Monde Sauvage in Aywaille, Belgium, and Crystal has nieces and nephews in Belgium, Denmark and France.
The Oldest...
Nan and friend in 2014 in Toledo
28 year old Nan, short for Nanuyaak, was born in the Alaskan wilderness in late 1994. She lived in Toledo for many years, is the mother of Nikita, and now lives in the Como Zoo in St. Paul, Minnesota.
27 year old Chinook was born in the wild in Manitoba Canada in 1995. She came to the San Diego Zoo when she was about a year old.
27 year old Snowflake was born November 28, 1995 in the Buffalo Zoo. She had spent most of her life at SeaWorld San Diego with her late German friend Szenja, with several periods in the Pittsburgh Zoo with male Koda, and now lives alone in Pittsburgh.
26 year old Anoki lives in Seneca Park Zoo in Rochester NY, where she was born after living for some time in the Maryland Zoo in Baltimore.
 |
Neil in 2014 in Como Zoo
|
As for the males, 27 year old Neil of Como Zoo is the oldest. He and his twin brother Buzz were born in Louisville December 9, 1995. Sadly, his beloved twin brother Buzz died in August of 2020. 26 year old Kiska and Koluk were born November 19, 1996 in Salt Lake City. Since 1997, they have lived in ABQ Biopark in Albuquerque NM.
The Youngest...
Births in the past seven years, 7 girls and 3 boys (if my guess about Crystal's cubs is correct), are all children or grandchildren of Marty and Crystal in Columbus:
Nora in Columbus, daughter of Aurora and the late Nanuq in 2015.
Hope in Toledo, daughter of Crystal and Marty in 2015.
Amelia Gray in Columbus, daughter of Anana and the late Nanuq in 2016.
Nuniq and Neva in Columbus, son and daughter of Aurora and the late Nanuq in 2016.
Kulu in Columbus, son of Aurora and Lee in 2019.
Astra and Laerke in Detroit, daughters of Suka and Nuka in 2020.
Boy Cub? and Girl Cub? in Toledo, with mother Crystal and father Nuka. No names yet, and the gender of Crystal's twins has not been announced, so I am just going with my best guess for the purpose of this survey, based on the shapes of their faces, sometimes a good indicator, sometimes not, that they are a boy and a girl. Update: It is TWO BOYS!
And then there is the rescued orphan in the Alaska Zoo, a boy, no name yet, but he is about a year old.

My survey this time is by zoos, from west coast to east.
Western:
San Diego Zoo
The San Diego Zoo still has its three wildborn bears, 27 year old Chinook and 22 year old twins brother Kalluk and sister Tatqiq.
Chinook was born in the wild in Manitoba Canada in 1995. She came to the San Diego Zoo when she was about a year old. Two years later, cubs Neil and Buzz from Louisville joined her in San Diego. In 2001, wildborn brother and sister twins Kalluk and Tatqiq joined the group, and at the end of 2001, Neil and Buzz left. Since then, Chinook, Kalluk and Tatqiq have formed a stable trio at the San Diego Zoo. Chinook has never had cubs.
Twins Tatqiq and her brother Kalluk were born in the wilds of Canada in the winter of 2000. They came to the San Diego Zoo as young cubs. It was decided that Chinook would be mate to Kalluk, and Tatqiq would stay with her brother as a playmate. The three bears all get along well. Tatqiq has been on birth control, and thus is unable to have cubs now.

In the Oregon Zoo in Portland, following several years of construction to improve the habitat, two young bears have arrived. Seven year old Nora, daughter of Aurora, was raised by keepers in Columbus and lived for several years in Portland, before moving to Salt Lake City, where she was companion to her Aunt Hope, who is the same age. Hope has now moved to Brookfield. Nora has returned to Portland, and was joined last year by her six year old sister/cousin Amelia Gray, also born in Columbus, and who has lived in the Maryland Zoo for the past few years. Amelia Gray is the daughter of Aurora's twin sister the late Anana. The late Nanuq is the father of both Amelia Gray and Nora.

Alaska Zoo
21 year old Cranbearry lives on her own in the Alaska Zoo. She has never had cubs. Cranbearry is the older sister of twins Nuka and Koda, so she is the aunt of two year old cubs Astra and Laerke in Detroit, as well as the new cubs in Toledo. She was born in November 21, 2001 in Denver.
In November, a one year old orphaned cub was found alone in Prudhoe Bay, and brought to the Alaska Zoo, where he was quarantined and is being cared for. He has not been given a name yet. Since the Alaska Zoo only has Cranbearry, an older bear, I expect that they will want to keep the youngster as a permanent resident.
Hogle Zoo
The Hogle Zoo in Salt Lake City sent away young Nora and Hope, and welcomed 16 year old Nikita, who came from the North Carolina Zoo. Nora went to Portland and Hope went to Brookfield in Chicago. Nikita is the son of the late Marty and wildborn Nan. He was born November 21, 2006, in Toledo.
Newly arrived in Salt Lake City is six year old Neva, twin sister of Nuniq, who was born in Columbus Ohio on November 14, 2016. Neva and Nuniq were the offspring of Aurora and the late Nanuq.
Nikita is the son of the late Marty, who was Neva's grandfather, which shows how limited the breeding pairings are in the U.S.
ABQ Biopark
In the ABQ Biopark (formely the Rio Grande Zoo) in Albuquerque, New Mexico, we find the 26 year old Kiska and Koluk, twin brothers who have lived together all their lives. Kiska and Koluk were born November 19, 1996 in Salt Lake City. Since 1997 they have lived in the zoo in Albuquerque. Kiska and Koluk are brothers of the late Anana (of Buffalo, Cincinnati and Detroit), and half brothers of the late Aurora (mother of four) of Rochester, and of Denali (father of 8) of Sapporo Japan.

Midwest:Kansas City Zoo
The Kansas City Zoo was home to Berlin, who just passed away at age 33. She leaves behind young Nuniq, six year old son of Aurora and the late Nanuq. Along with his twin sister Neva, Nuniq was born in the Columbus Zoo on November 14, 2016, to Crystal and Marty's daughter Aurora and the wildborn Nanuq, who was also father of Luna in Buffalo, as well as father of Aurora's first cub Nora, and Aurora's twin sister Anana's daughter Amelia Gray.

St. Louis Zoo
Ten year old Kali was born in the Alaskan wilderness in late 2012. His mother was shot by a hunter, who realized there was a cub and tracked him down in his den. He was taken to the Alaska Zoo, kept there for a few months, and then flown to the Buffalo Zoo to be a companion for young Luna, who was being raised by hand. Kali now lives alone in a wonderful new habitat in the St. Louis Zoo. As a property of the Department of Fish and Wildlife, he cannot be part of the breeding program.

Como Zoo
The Como Zoo in St. Paul Minnesota is still mourning the loss of Buzz, but his 27 year old twin brother Neil is being comforted by his new companion 28 year old Nan. Young Kulu is a new arrival there too. Como Zoo is home to the oldest female and the oldest male polar bears in the US, and also one of the youngest polar bears, Kulu.
 |
Neil, Nan and Kulu in Como Zoo in 2022 |
28 years old Nan, short for Nanuyaak, was born in the Alaskan wilderness in late 1994. The cub was taken to the Alaska Zoo in Anchorage, where she stayed for five months. She lived in the Point Defiance Zoo in Tacoma until she was six years old. Nan moved to the Toledo Zoo in 2001, where she gave birth to Nikita in 2006, with Marty as father, the same year Crystal gave birth to twins Aurora and Anana with Marty also as the father. Nan moved to Brookfield Zoo in Chicago in 2017, where she lived with Marty's younger brother Hudson. Now she is in the Como Zoo in St. Paul Minnesota as companion to Neil, and now holds the honor of being the oldest polar bear in a US zoo.
 |
Neil |
Neil and Buzz were named after the first two humans to walk on the moon. They were born December 9, 1995 in the Louisville Zoo, then lived at the San Diego Zoo from 1997 to 2001. They have lived at Como Zoo in St. Paul Minnesota since then, except for a two year span in 2008-10 when they enjoyed living in Detroit while the Como Zoo polar bear habitat was being expanded and renovated. While they lived in Detroit, the boys loved playing with young cub Talini, daughter of rescued circus bear Bärle.
At Como Zoo, Neil and Buzz have played host to three grizzly bears from a flooded out Minot ND zoo. Later, they welcomed their niece Berlin, who also had escaped from a flooded zoo in Duluth. They shared their habitat with young twins Suka and Sakari while the cubs waited for their new exhibit at Henry Vilas to open.
Neil and Buzz come from the Louisville family of bears. Their older brother Icee was the father of twins Berlin and Yukon at the Cincinnati Zoo. Their older sister Ulu was the mother of Berit, longtime resident of the Cincinnati Zoo and current resident of Henry Vilas. Their parents also famously had rare triplets in Louisville in 1992, which included the late and much loved Aquila. Neil and Buzz were neutered so they could stay together and not fight. At the time, it was thought their genes were well represented and there were plenty of polar bears.
This lovely senior couple has recently been joined by youngster Kulu from the Columbus Zoo, now three years old. They all play together and have great fun. Kulu wears the oldsters out.
Kulu was born November 28, 2019 in the Columbus Zoo, a fourth cub for Aurora and a first for father Lee. Kulu's older half siblings are Nora, Neva and Nuniq, and Amelia Gray is his cousin.
Brookfield Zoo
Hudson and Hope are living together in the Brookfield Zoo in Chicago. Because of the limited gene pool. Hope, daughter of Marty and Crystal in Toledo, is paired with Marty's brother Hudson. That's right, Hudson is Hope's uncle.
Seven year old Hope was born in Toledo on December 3, 2015, to Marty and Crystal. She lived in the Hogle Zoo in Salt Lake City with her niece Nora of the same age for a few years and now is in Brookfield. She is sister to Aurora and Anana, Siku, Suka and Sakari, Bo, and is half sister to the new Toledo cubs and also to Nikita.

Hope in the Toledo Zoo in 2016 |
Crystal was born in November 10, 1998, in Monde Sauvage in Belgium. Her older sister Blanche was born in 1993, and is still there, never having left the zoo. Blanche is mother to son Nanook, now in Denmark, and daughter Qannik, who still lives with her mother, so these two are first cousins of all Crystal's cubs. Nanook is father to Danish Siku and Nuno in Denmark and Nanu in France, so Crystal has a niece and two nephews in Europe. Crystal's twins can be seen on a dencam set up by the Toledo Zoo.
The father of the twins, 18 year old Nuka, has just left the Toledo Zoo for another AZA zoo, although it has not been announced to where. But since the plan was always for Nuka to return to Detroit when Suka had weaned Astra, I expect that this is where he is. Also, there are only three proven fertile females in the US zoos. Crystal is busy with the twins, and Lee has just returned to Aurora in Columbus, so that just leaves Suka in Detroit.
Detroit Zoo
The Detroit Zoo is home to 10 year old Suka and probably 18 year old Nuka, and their twin daughters Astra and Laerke, 2020's only cubs in the USA, and none were born in 2021. Astra was raised by her mother, and twin sister Laerke was raised by keepers. For a time, a Grizzly cub named Jebbie came to Detroit as a playmate for Laerke, but he has grown too large and is now relocated to a sanctuary in Colorado.

Nuka and his twin brother Koda were born November 25, 2004 in Denver, to parents Voda and Kavek. They both moved to Pittsburgh when they were two years old. In 2011, Nuka moved to Detroit as a mate for Talini. Then Talini moved to Lincoln Park, and Suka moved in. In 2020 Suka and Nuka welcomed twin daughters, Astra and Laerke.
In January of 2022, Nuka moved to Toledo to live with Suka's mother Crystal, whose longtime mate Marty had died. This would give more room Suka and her young cubs in Detroit. Now it seems that Nuka is ready to return.
Suka and her twin brother Sakari were born November 21, 2012 in the Toledo Zoo to Marty and Crystal. The twins moved to Como Zoo in St. Paul, then to the new habitat at Henry Vilas Zoo in Madison Wisconsin. Suka now lives at the Detroit Zoo. Before Astra and Laerke were born, Suka had given birth to cubs for the previous two seasons, but they did not survive.
Columbus Zoo
Twin sisters 16 year old Aurora and Anana lived together all their lives, from the time they were born in Toledo, for several years in Pittsburgh and then their many years together at the Columbus Zoo. Tragically, Anana died last October. The zoo's most recent male polar bear Lee had spent the past several years in Louisville, but now he has returned, so Aurora will not be alone.
Aurora and Anana were born in the Toledo Zoo November 25, 2006, four days after Nan gave birth to Nikita in the den next door. The father was the same, Marty. The twins' mother was Crystal, who was born in Belgium.
The Toledo Zoo was a busy place during those years, with Nan raising Nikita, and Crystal raising the twin girls.
Twins Aurora and Anana moved to Pittsburgh in 2008, and to the new polar bear habitat at the Columbus Zoo in 2010.
Aurora gave birth to Nora in 2015, who was raised by keepers.
In 2016, both sisters gave birth. Aurora had twins, Nuniq and Neva. Anana had Amelia Grey. The father of all four cubs was the late Nanuq, who had previously fathered Luna in the Buffalo Zoo with the late Anana. Three years ago, Aurora gave birth again to a boy named Kulu with Lee as the father. Kulu moved to Como Zoo in St. Paul, Minnesota in late 2021.

23 year old Lee and his twin sister (North Carolina) Anana were born November 27, 1999, in Seneca Park Zoo in Rochester NY to Aurora and Yukon.
Lee has lived in Lincoln Park Zoo in Chicago several times, in Milwaukee, in Detroit, and then in Denver with Cranbearry. He moved to the Columbus Zoo in late 2018, and in 2019, Aurora gave birth to Kulu, a little boy cub, Lee's first.
