When it comes to polar bears (Ursus maritimus), providing effective environmental enrichment is essential for their overall health and happiness.
In this blog post, we will investigate the latest findings in environmental enrichment for polar bears and explore creative strategies to enhance their lives.
Understanding Polar Bears
Zoo staff are well-versed in the fundamentals of environmental enrichment, recognizing that it is not just about keeping polar bears fed and healthy, but also about stimulating their minds and encouraging natural behaviors. Polar bears, with their vast natural habitats in the Arctic, demand unique attention to detail in creating environments that mimic their wild homes. Without adequate enrichment, captive polar bears exhibit stereotypic behaviors.
The Case of Gus the Polar Bear
At the Central Park Zoo, Gus was one of the most popular animals in the 1990s. Unfortunately, it was his constant swimming (sterotypies) that attracted attention. You can see him in this video. Gus swam laps in his pool for hours, every day. Keepers experimented with polar bear-specific enrichment practices, which dramatically helped Guy adapt to his environment. Here is what has proven to be effective enrichment practices for polar bears in captivity.
Physical Enrichment
Physical stimulation is crucial for polar bears, known for their playful and curious nature. Laurie J. Gage USDA APHIS Animal Care, presented an interesting paper on designing polar bear enclosures and exhibits. Laurie said, “Providing adequate space for polar bears not only gives them more incentive to exercise but may help to prevent stereotypies.” The Australian Society of Zookeepers has provided their guidelines to polar bear enrichment and is a handy reference.
Water Features
Polar bears are exceptional swimmers, spending a significant amount of their time in the water. Creating expansive water features within their enclosures not only provides opportunities for exercise but also mimics their natural aquatic environment. Adding items like our Iceberg Float or the Ice Flow provide for interesting water activities. Both are polar bear favorites in and out of the water. A recuring enrichment item used by zoos are floating balls such as the Otto Aqua Ball. Polar Bears will play with the balls on land and in the water. Aqua Balls are manufactured specifically for rough play by big bears.



Sensory Enrichment
The Arctic is a sensory-rich environment, and replicating these sensory experiences is crucial for polar bears’ well-being. The bears have an excellent sense of smell. Scent trails made with animal scents or aromatic herbs can engage their keen sense of smell. Polar bears enjoy foraging, especially for food. Research shows that providing forage challenges keep the animals engaged and avoids stereotypic behavior. The Stump Feeder can be packed with fish, meat, and vegetables. Bears roll, carry, and explore the feeder to obtain a snack.

Cognitive Enrichment
Engaging the bears in activities that require problem-solving and cognitive skills is essential. Puzzle feeders, where bears need to manipulate objects, can be both mentally and physically stimulating. The Cap Feeder is tough enough for bears and provides a simple to load feeding puzzle. A non-food cognitive device is the Bear Bell. We have discovered bears like to nudge and nose the stainless-steel bell, just for fun! Pings Pearls is another unique device that bears simply love. See for yourself!

Conclusion
One of the key takeaways from zoos and researchers is that polar bears benefit from routine enrichment sessions with caregivers and they like to have variety within the routines. Changing up the enrichment toys seems to keep the bears interested and engaged. The Calgary Zoo has a great video explaining all the techniques they use with their polar bears. By integrating diverse forms of enrichment, you ensure that these Arctic ambassadors thrive in captivity while fostering a deeper understanding and appreciation among visitors. Through dedicated efforts, we can contribute to the well-being of polar bears, not just as residents of our zoos, but as ambassadors for their wild counterparts facing challenges in the changing Arctic landscape.
