Pandas Keep Cool

It’s been warm in San Diego lately, and some of you may be wondering how our giant pandas are kept comfy. Senior Keeper Kathy Hawk filled me in on the hot-weather protocol used in the San Diego Zoo’s Panda Trek.

There are thermometers in shaded areas of each panda enclosure, and if the temperature reaches 85 degrees Fahrenheit (29.4 degrees Celsius), the pandas are given access to their air-conditioned bedrooms. The panda station has its own ice-making machine, so keepers can fill tubs with ice to make ice beds for some cool lounging, or they can make an ice-cube pile for flopping on (the pandas, not the keepers!). Sometimes food treats are added to the ice to encourage use.

You may have seen the mist fans in each yard. These fans mix water and air to blow a cooling mist into the enclosure. Kathy said the pandas really seem to enjoy the shrouded mist the fans create. Ice treats or popsicles made with applesauce or other panda delights are offered as both enrichment and as another way to keep cool. And, of course, each enclosure has a pool to soak in.

Kathy emphasized that anytime there is high humidity, no matter the actual temperature, the pandas are pulled off exhibit. Keepers are pro-active about avoiding any signs of early heat stress with these precious bears, and all three are closely monitored.

Thank you, panda keepers, for always taking such good care of these black-and-white bears. Your work is much appreciated!
