The Oregon Zoo will soon say goodbye to Nora, a remarkable polar bear who enjoyed viral stardom as a cub and overcame all manner of ursine life obstacles as she grew.
Why it matters: Nora is a special bear — to her species, to Portlanders and to me personally.
Catch up quick: Nora was abandoned by her mother soon after she was born at the Columbus Zoo in Ohio in 2015, and zookeepers made the risky decision to raise her by hand.
- Only a handful of newborn polar bear cubs had been hand-raised, and the five-woman team of keepers knew there was no guarantee of success.
- Within a few months, Nora developed metabolic bone disease — suffering from twisted bones and small fractures in some of her limbs — and her keepers weren't sure she'd survive.
- But the underdog cub became a viral sensation at the same time, with millions viewing videos of her feeding and playing with her keepers.
Zoom in: A change in her formula proved effective, and Nora soon grew large enough to need a new home, moving to Portland for her first residency in 2016.

- At the Oregon Zoo, her keepers noticed signs that she was struggling to adjust — after so much time around humans, it was unclear if she knew how to be a polar bear — and she was put on a regimen of antianxiety medications and antidepressants.
- The meds worked, but Nora was alone and needed the company of another bear. So ahead of construction of a new habitat in Portland, she was moved to the Hogle Zoo in Salt Lake City.
- She returned to Portland in 2021 and, despite a hitch in her gait and ongoing skeletal issues, has seemingly lived the life of a happy and healthy bear.
Zoom out: As miraculous as Nora's early life was, how she came to be in a zoo is just as remarkable.
- That story begins in 1988 in Wales, Alaska, a tiny Native village on the Bering Strait.
- Gene Agnaboogok, a hunter in the village, was on the sea ice looking for game when he fell through the roof of a polar bear den, landing on top of the mother bear.
- She attacked and he shot her, but he rescued the two cubs who remained.
One of those cubs would later father Nora at the Columbus Zoo in Ohio.
💭 My thought bubble: I was able to write most of what you just read from memory after I reported extensively on Nora's early life for a five-part series I wrote for the Oregonian, which I later expanded into a book.
- Aside from my pets, I've never known an animal as well as I know Nora, and it's been a privilege to document what she has meant to so many people.
- I haven't visited her as much as maybe I should have, but it was nice knowing she was close by. I'll miss her.
What's next: Nora is slated to say goodbye to Portland this fall as she heads to the Henry Vilas Zoo in Wisconsin, where zookeepers hope she'll produce her own cubs.
- The Oregon Zoo's polar bear habitat won't be empty for long — 2-year-old Kallik is set to arrive after Nora departs.
