The Fascinating Life of San Diego Zoo’s Polar Bears
SAN DIEGO (FOX 5/KUSI) — Recently, a video went viral on social media showing a polar bear at the San Diego Zoo looking lethargic, drooling, and panting in its enclosure. This footage caught the attention of animal lovers and experts alike, raising concerns about the well-being of these magnificent creatures. The San Diego Zoo responded to the speculation, elaborating on the behavior observed in its polar bears, particularly during the breeding season.
This year, spring coincides with the mating season for polar bears. According to zoo officials, their male polar bear, Kalluk, is currently experiencing heightened breeding interest towards his counterpart, Chinook. The zoo explained that during this period, polar bears tend to conserve energy, focusing more on mating behaviors than on hunting or feeding, which may explain Kalluk’s apparent lethargy.
Wildlife care experts have been closely monitoring Kalluk and Chinook during this critical time, which can stretch over several weeks. Their watchful eyes ensure that both bears remain healthy and active, despite the public’s concerns. Interestingly, polar bears at the zoo thrive in a climate reminiscent of an Arctic summer day, which is quite a contrast to their natural habitat.
Unlike their brown and black counterparts, polar bears do not hibernate; only pregnant females retreat to dens for the winter. When not hunting, these bears can rest for up to 20 hours a day—a behavior perfectly suited to their energy needs when mating. The San Diego Zoo has a rich history with polar bears, housing their first in 1917 and currently caring for these remarkable animals that are classified as threatened under the Endangered Species Act.
The diet of polar bears at the San Diego Zoo is just as fascinating as their behavioral patterns. They receive a fortified meat-based carnivore diet, accompanied by various treats such as trout, root vegetables, and lettuce. Staff ensure variety by occasionally adding cow femur bones and thawed rabbits to their diet, further enriching their experience at the zoo.
After mating, the female polar bear typically gives birth to one to three cubs, often twins, during December or January. Newborn cubs weigh about a pound and are hairless with closed eyes. By April, these cubs can grow to over 20 pounds and begin to explore the world around them with their mother. They usually reach independence by the age of two.
The polar bears at the San Diego Zoo provide a unique opportunity for the public to engage with these extraordinary animals. For a closer look at their daily activities and interactions, visitors can watch them at any time on the zoo’s polar bear live cam.
As we observe Kalluk and Chinook’s journey, it prompts a larger discussion about the importance of wildlife conservation and the role zoos play in protecting endangered species.
