The Toledo twins at one year

A little watermelon for the cubs


Kallu and Kallik clean up after the party


Kallik and Kallu, twin sons of Crystal and Nuka, were treated to a grand birthday party on November 11 in honor of their first birthday. Mom Crystal turned 25 the previous day, and she was included in the festivities of course.


The cakes before the bears came roaring in. 


Watermelon is the recent favorite treat.

Three bears and a play spool. 


The keepers had built three "birthday cakes" made of watermelon, lettuce, lard and a carrot on top for a candle, each sitting on a block that had been labeled for each bear. Kallik and Kallu's boxes included their nicknames, Lightning and Thunder.  

Some of the birthday cards made by the children.


A good crowd of fans turned out for the party, including many children, and many made cards for the birthday boys. Since the zoo has shown the growth of the cubs since birth on a public webcam, many have followed K and K since those early days, and they have many fans.

Crystal in back, and one of the cubs, probably Kallu,
 who likes to be near mom.

The bears cannot read, or at least did not bother to check the writings, so just went to the nearest cake, and after that, just traded off. 

The birthday party for Crystal and her cubs.

The keepers told me that once a year, they try out different produce for the bears to see if their tastes have changed. Even though these foods are not available in the wild where the bears live in nature, zoos have found that polar bears really love their fruits and vegetables when they can get them. Right now, the Toledo bears prefer watermelon. 

Crystal is also very fond of seaweed, so there were balls of seaweed for her.
Yummy seaweed for Crystal

Some fish were also given to the bears as part of the birthday feast.




Kallu with some of the fish treats.


Kallik was much smaller when he was born, maybe half the size of his brother, but he has caught up since then, and now his weight is reported at 320 to 340 pounds. Kallu, the bigger cub, weighs 340 to 360 pounds.

When they were younger, it was easier to tell Kallik from his bigger brother, but now they are nearly the same size. How to tell them apart? Kallu has a longer tail, and there is less fur on his tail so the black skin shows through. Kallu sometimes has a spot on his forehead too. 

Because Kallu has less fur on his tail,
 there seems to be a black streak. One way to tell them apart.

During their first year, Kallu has tended to stay near his mother, while the smaller Kallik has been more independent. But on Saturday, while the boys did play together in the water for a bit, and Kallu tended to check in with his mother quite often, mostly they were off on their own, each doing their own thing, after consuming most of the birthday treats, leaving Crystal to do as she wished, sometimes napping, sometimes just watching the boys play.

Kallu plays with the pickle lid, and Crystal check in.

Kallu and Kallik both love playing with the black plastic pickle lids, hiding them, flipping them around, tossing them in the air. 

Kallik plays with the floating iceberg, and Crystal observes.

Kallik played quite a bit with the "new" floating iceberg, which was brought out for their birthday. But he would incorporate his lid in the play. 

Kallik having a blast with the new iceberg.

Kallik and Kallu's father, Nuka, returned to the Detroit Zoo last spring, and now Suka, who is also Crystal's daughter, is said to be denned up and awaiting the birth of cubs again. Suka gave birth three years ago to twin girls, and one was raised by keepers. These girls now live in the Point Defiance Zoo in Tacoma, Washington.  

Most likely, Nuka will not return to Toledo, since Crystal is 25 years old and her genes are so well represented, Kallik and Kallu will most likely be her last cubs. She is already mother to nine bears, which includes three sets of twins.

As the birthday morning wore on, the cubs enjoyed playing together in the water.

Sort of Synchronized Swimming.

Playing together but not really together.

Maybe something fun over here?

Time to get up and check out the party leftovers.


Someone caught a fish!
It was part of the party treats laid out.
Kallu was carrying them about.

The black plastic lids were big hit. Great for tossing, and the perfect size to carry around.

Kallu is obsessed with the black plastic lids.
He hides them and then digs them out again.


Kallu balances, then flips it into the air.


Kallik likes the lids too.


Back to the party room to clean up. There are a few bits and pieces and the cubs rub their faces on the paint from the signs.

Kallu got a third eyebrow with the paint. Here he is with Crystal. 


Kallu's new fashion make-up.

Crystal and Kallu

Kallik with some fish.

Kallik got the most paint on his little face.
 A little yellow and lots of black.
 It all came off after he jumped into the pool a few minutes later.
 Cute while it lasted.

 
Kallik likes the spool.

Kallu with the spool. See the black stripe on his tail?

Happy First Birthday to our little Arctic cubs. This is Kallu.

And another surprise is coming this week, a belated birthday gift. They will surely adore playing with their new giant pickles, sent by their fans in Polar Pals.

Astra and Laerke - twins separated at birth

Laerke, the hand raised cub at the Detroit Zoo.
Her twin sister Astra was raised by their mother.

 
Astra plays with part of a spool and a bone joint in the Icepack region.


Laerke juggles the other part of the spool, in the Tundra area.

Twins Astra and Laerke will be two years old in two weeks. They share the same parents, and the same birthday. But these little girl cubs have lived separate and  parallel lives from almost the beginning.

Astra far away, and twin sister Laerke, closer. In October 2021.
They are separated by a moat.

They were born November 17, 2020, to parents Suka and Nuka in the Arctic Ring of Life of the Detroit Zoo. Suka had given birth during several previous seasons, but the cubs had been stillborn or short-lived. As the new mother was being watched via dencam, keepers could see that one of the cubs was struggling, and soon was nearly lifeless, so they intervened and took Laerke away for emergency medical help. 

So it happened that Astra was raised by her mother, and Laerke was bottle-fed and raised by humans. 

Astra and Laerke were the only cubs born in USA zoos in 2020, and no cubs have been born since, so they are the youngest polar bears in the USA.

In the spring of 2021, visitors to the zoo could see little cub Astra romping around the meadow with her mother Suka, while Laerke remained behind the scenes, a mysterious hidden cub. Later in the summer, Astra was introduced to the big saltwater pool, during which time father Nuka was rotated through whichever half of the habitat Suka and Astra were not occupying. 

Suka swimming with her cub Astra last year.

The Detroit Zoo has an amazing saltwater pool, with a viewing tunnel for visitors. Here are Suka and Astra last year.

Mother Suka has taught her daughter Astra through swimming and playing with her.  Laerke has had to learn on her own.

Mother Suka and daughter Astra play underwater games last year.

The underwater viewing tunnel is an astounding way
to experience the bears. Here are Astra and Suka.



Visitors get a unique close up view of the polar bears from the underwater tunnel.


Suka and Astra chasing underwater last year.

During those months, Laerke came out to play only after the zoo closed, and the public never saw her, except in a few tantalizing photos. 

Astra gained weight at a proper rate, but Laerke always lagged behind. As they approached their first birthday, Astra weighed 200 pounds, double that of her little sister. 

During those spring and  summer months, Astra was playing with her mom, learning social skills, swimming skills and more, learning how to be a bear. 


A scene from about a year ago, Astra, across the dividing moat, watches grizzly cub Jebbie and her sister Laerke,
maybe wanting to join in the fun.

Laerke on the left, her mother Suka on the right. While they are curious about each other, Suka does not realize that Laerke is her cub, and would feel that she had to defend Astra from the strange cub.

Laerke was doing well with her human caretakers, but needed a bear companion so she could learn the social skills of how to be a bear.  The zoo searched for such a cub, and a little grizzly bear boy named Jebbie, who had been found abandoned in Alaska, was brought to the Detroit Zoo as a companion for Laerke. This way both bears, Laerke and Jebbie the grizzly cub, could benefit by playing and interacting with another bear.

Jebbie and Laerke, last year.

The arrangement worked out very well, and the cubs played together for many months of important development, first behind the scenes, and then in October, the public could see Jebbie and Laerke play together in the tundra area for short periods, for Laerke had her limits, and would tire after an hour of hard play. Both cubs delighted in having a playmate, and benefited greatly from the friendship.

Laerke and Jebbie, in October of 2021.

Jebbie, being a grizzly and a land animal, would tend to stay on shore, and Laerke spent more time in the water, but these two were never far from each other.

To give Suka, her cubs and Jebbie more time to play outside, father Nuka moved to the Toledo Zoo, where he remains at this time, living with Suka's mother Crystal.

Laerke and Jebbie racing around in October of 2021.

The pairing of the polar and grizzly cubs worked well for most of a year, but Jebbie grew much faster than Laerke, and he also has some very long claws. Late this past summer, the keepers saw that Jebbie had outgrown the friendship. For safety reasons, the two cubs were separated, although they were still near each other in the bedroom area. In the fall, Jebbie was moved across the road to the grizzly bear area, where he had a small enclosure all to himself, while he awaited his big move. Jebbie is now in a huge wildlife sanctuary in Colorado, where has plenty of natural space, and he is reported to be doing very well there.

Looking like she's playing a musical instrument, this is Laerke.

She is playing alone these days,  but Laerke is still having lots of fun. 


Showing her strength, Laerke plays.

Fluffy Laerke. The cubs had picked up lots of burrs in the Tundra area, so gardeners came in and cut those plants down.

So now Laerke is an "only child" again, but she is very good at entertaining herself with swimming in the big pool and tossing around toys.

Laerke with Keeper Rick. She keeps her eyes on him.

 in the Ice Pack region of the Arctic Ring of Life.

Laerke has a real bond with her keepers, and likes to be near them, even when she is out in the enclosure. She needs this emotional support, just as Astra gets attention from her mother.

Laerke is drawn to the youngsters at the viewing window.

Laerke also loves the attention from the visitors, especially the children.


Laerke swimming to and fro.


Laerke still weighs a lot less than her sister. Astra now weighs about 500 pounds, and her little sister Laerke weighs 297. Their mom Suka weighs in at about 750 pounds. 

Laerke plays through the glass with a young visitor.

Astra is stronger than her sister and has better coordination. Laerke got off to a rocky start, and she is still playing catch up. She has a strong spirit and plenty of determination, though.

Astra on the bottom, plays with a ring,
 as mother Suka tries to steal it.


Astra is strong and can lift the ring every which way.

Look Mom! Astra shows off for her mother Suka.



Laerke, the weaker twin playing by herself,
struggles to lift the ring, but still has fun with it.

Laerke frames herself with a fun toy,
 one that Jebbie liked to play with too.


The girls are approaching their second birthday, to be celebrated on November 17. The plan, as I understand it, is that when Astra is weaned and separated from Suka, the girls may very well be reunited, and Laerke will again have a playmate.

Astra and Suka, sometimes together, often apart these days.

Mother Suka is gradually distancing herself from Astra, preparing for weaning, but right now, there is still some nursing going on.

It is the way of polar bear world that cubs leave to start life on their own at about the age of two in the wild. Then father Nuka can return from Toledo, and be reunited with Suka. 

Astra swimming in the viewing tunnel area.
 She can swim and play all day.


Laerke swims well enough, but she doesn't have the stamina of her sister, and she wants to go back inside after swimming for an hour.

Laerke is still a lot smaller than her sister, so reuniting the two may be put off for awhile.

This is pure speculation, but I hear that Point Defiance Zoo in Tacoma Washington, after the death of elderly bears Boris and Blizzard, is redoing its polar bear habitat, and will be home to some polar bears in 2023. Maybe that is where the twins will end up.
