Columbus Zoo preparing to welcome Lee, an adult male polar bear

Local News

Columbus Zoo and Aquarium team members are looking forward to welcoming Lee, an 18 year old male polar bear, who will be arriving from Denver Zoo later this fall.

Currently, there are only 44 polar bears in North American zoos, and the species is facing increasing threats in their native range. After completing a mandatory quarantine period upon his arrival, Lee will be introduced to 11-year-old twin sisters, Aurora and Anana, for potential breeding.

According to the Columbus Zoo, it has been successful in its polar bear breeding program with four surviving cubs born since the Zoo’s Polar Frontier region opened in 2010.

One of those cubs, Nuniq, a male who now weighs over 650 pounds, was recently moved to the Henry Vilas Zoo in Madison, Wisconsin.

Two of the females successfully born at the Columbus Zoo, Amelia Gray and Neva are set to move to the Maryland Zoo in Baltimore soon.

The relocation of these bears allows for the opportunity for Lee to be introduced to two other bears who will remain at the Columbus Zoo, Anana and Aurora. 

These moves were recommended as part of the Association of Zoos and Aquariums’ (AZA) Species Survival Plan® (SSP), a cooperatively managed program designed to maximize the genetic diversity and increase the population sustainability of threatened and endangered species in human care.

Currently, there are only 44 polar bears in North American zoos, and the species is facing increasing threats in their native range.

This breeding plan is important to the survival of this species, which in 2008 became the first species to be listed under the Endangered Species Act as threatened primarily due to climate change.

“Not only is Lee sure to be beloved within our Central Ohio community, but we know and appreciate that he is an important ambassador for polar bears in their native range. We are proud to soon welcome Lee and continue working toward protecting the future of this threatened species,” said Columbus Zoo and Aquarium President and CEO Tom Stalf.

Polar bears are native to the circumpolar north, including the United States (Alaska), Canada, Russia, Norway, and Denmark (Greenland). They are at the top of the Arctic food chain and primarily eat seals. Polar bear populations are declining due to the disappearance of sea ice, and experts estimate that only 20,000-25,000 polar bears are left in their native range.

Some scientists believe if the warming trend continues, two-thirds of the polar bear population could disappear by the year 2050.

The Columbus Zoo and Aquarium is dedicated to conserving polar bear populations in their native range. Since 2008, the Zoo has contributed more than $250,000 to research benefiting polar bears in the Arctic. The Zoo is also designated as an Arctic Ambassador Center by Polar Bears International (PBI).

At the Columbus Zoo, visitors are encouraged to do their part to save this amazing species by turning off lights when leaving a room, minimizing their use of heating and cooling units, and other ways to reduce energy consumption.
