For most of the last week, panda mother Bai Yun has been given access to her garden room at the San Diego Zoo’s Giant Panda Research Station throughout the day. She hasn’t really been out there much, though we have noticed her sitting in her sunroom and looking out to the grassy garden floor. It’s as if she is toying with the idea of exploring, but not yet sure if she should indulge herself.
We offer garden room access because it is the natural progression for a postpartum panda to need more time away from her cub, not because she tires of caring for her youngster, but because nature requires this of her. A wild panda isn’t provided with high calorie, nutrient-dense biscuits, yams, and carrots each day. Instead, she must rely on the nutrition provided by bamboo, which is comparatively nutrient and calorie poor. As her appetite comes back online from her postpartum fast, and the energy drain of lactating for an increasingly hungry youngster take its toll, mother panda must spend more and more time out of the den meeting her dietary needs.
Of course, Bai Yun is not a wild panda, and she does benefit from regular feedings by her keepers. She can count on twice daily provisioning of the best bamboo we have to offer, and a nice pile of supplemental foods to boot. She doesn’t have to wander far or be gone long to meet her needs. But she still seems to have that drive to be out of the den, away from the cub, for periods of the day. Surely those among us with children of our own can relate to the need for a little “me time”?
And so we have offered Bai Yun her garden room. In the past, once she determines that it is time, she will move outside during the day and rest atop her platform. She seems to enjoy the breeze, the sunshine, and the opportunity to interact with her keepers. Bai Yun is still very close to the den and can easily hear the cub should it vocalize a need. But there is something about emerging from the darkness of the den into the light of a warm fall afternoon that seems to be of value to Bai Yun.
At the moment, she’s taking that emergence slowly. Today, after the morning cub exam, she chose to lie down in the bedroom, a few feet from the den. She was actually napping with her head hanging out into the sunroom. This absence wasn’t driven by hunger; she just wanted to be out of the den for a bit. She is beginning to seek that “me time” at her own pace. We expect that over the coming week or two we will see her explore that garden room and settle in atop her favorite platform in the corner.
Speaking of the cub exam, our staff managed to get their hands on the little guy in the den this morning. With an abdominal girth of 12 inches (30.5 centimeters), and a length of 16 inches (41.5 centimeters), you can understand why he reminds me of a sausage: he’s nearly as big around as he is long! Historically, however, he is not our heaviest cub thus far at 4 pounds (1.8 kilograms). So he’s a petite sausage, I suppose.
Mei Sheng started out a little lighter than his sisters but became one of our larger cubs after several months. Whether or not our newest panda cub will follow in his eldest brother’s footsteps remains to be seen.
