Polar bears at Louisville Zoo show promising signs of compatibility with hopes of welcoming cubs

LOUISVILLE, Ky. (WDRB) -- Polar bears at the Louisville Zoo are now interacting with each other just in time for breeding season.

It's been a long process to get to this point, and there is still more work to do, but, so far, zoo official have said the two are doing great together.

"It's some of the best stuff we've experienced here at the Louisville Zoo, I would say, in its existence, watching these two together," said Ron Evans, the zoo's general curator.

Tuesday marked a full week the bears have been interacting with one another, Evans said. They were eating, playing and swimming together.

"Certainly, the bear gods are smiling on us, because we got the giant snowfall, and there's nothing polar bears like better than each other than maybe a big pile of snow," Evans said.

Qannik, the female polar bear, is one of the zoo's most famous residents. The Louisville Zoo has been her home for years after she was found abandoned as a cub in Alaska.

Bo, the male polar bear, has been at the Louisville Zoo for about a year, brought in from another zoo as a potential mate for Qannik. The two have been able to see each other and smell one another but, until this past week, they hadn't been officially introduced.

"Finally, we started seeing some of the behavior signs we look for from female polar bears that lets us know she would be OK if we opened the door," Evans said.

He said it's rare to breed an animal brought in from the wild, but polar bears like Qannik can be extremely helpful for research.

"You don't want to create any sort of market for bringing animals in and reproducing them, so Qannik kind of fell under those U.S. Fish and Wildlife rules," Evans said. "So it stayed that way for many years. However, we know polar bears are critically important for research related to wild bear conservation. It's really tough to study wild polar bears."

Evans said through various partnerships, "they kind of finally came together and said, 'Hey, it's all right. Go ahead and see if we can't get some cubs from Qannik.'"

That's where Bo comes into the story. He's half Qannik's age and twice her size at a whopping 1,000 pounds. But so far, they're seeming to be a great match.

"Fortunately, things have been going fantastic," Evans said.

Because she was found in the wild, he said Qannik's genetics are extremely valuable.

"Oh, I think it's wonderful. It's exciting," said Marilyn Sadler, who visited the zoo Tuesday specifically to see the polar bears. "I'm thrilled to see them."

Evans said for polar bears, "courtship" begins in January and if all goes as planned, there's a chance for a cub birth sometime in November or December of this year. He said polar bears typically give birth to one to three cubs at a time, but admitted, breeding these bears is tricky.

As the polar bears get introduced to one another, zoo staff remain on hand with safety protocols in place, ready to intervene if necessary to ensure the well-being of both bears.
