Bai Yun and her cub are doing well, and their relationship has been evolving in predictable panda ways. As the cub grows, he can get bigger bellyfuls of milk with each feeding, which is followed by longer periods of sound rest. This means Bai Yun has more and more free time. What has she been doing with that free time?
Bai Yun continues to increase her time spent feeding outside of the den. She is taking in large quantities of leaf eater biscuits and produce. She is feeding on increasingly more bamboo as well, although she is not quite back to pre-pregnancy consumption levels. Bamboo feeding is a process, and it takes time, so as her intake continues to increase, we can expect her to be out of the den for longer periods. As the cub grows, the demands of lactation will also increase, so she will need every calorie she can get her paws on to ensure an abundant milk supply. Luckily, our keepers stand ready to assist.
Sometimes Bai Yun comes out of the den to rest on her own. She can most commonly be found only a few feet away from the den door, in her bedroom. This allows her a little extra space, some cub-free time, and some fresh air. The air in the bedroom is also a little cooler than the den, as our AC unit feeds directly to that room. Perhaps this has been a factor for her during some of our recent heat waves.
She has been utilizing the garden room, too. Those long-time viewers of Panda Cam will recall her favorite platform in that area. She’s taken several recent naps there. Sometimes Bai Yun takes the cub out with her. She’ll head out to the bedroom to feed or rest and plunk her youngster down beside her. Often the cub is asleep during these forays.
Occasionally, he is awake and squirming on the floor next to his mother. Once, Bai Yun even placed the cub on the scale in the bedroom, and keepers were able to use that opportunity to record a weight for him (thank you, Bai Yun!). So far, she has only introduced the cub to the bedroom; the garden room remains a destination for some future date of Bai Yun’s choosing.
Sometimes, Bai Yun can be observed wrestling with her offspring. She’ll turn the youngster around in her paws, nibbling at him playfully. At this stage, the cub is not able to return the play with much vigor, but watch closely—that will change soon. We’ve already seen the cub mouthing his mother’s paws, gnawing on digits. One element missing from your play-bout experience is the audio that staff can hear. Throughout most of Bai Yun’s play sessions, the cub is silent. Obviously, Bai Yun’s play activity is not bothersome to him. It may even be good for him in some way. Certainly it seems important for Bai Yun in some way we don’t yet understand.
None of what we have seen with Bai Yun since the birth of this cub is unusual or unexpected. She’s been the excellent mother we anticipated she would be. The cub continues to grow and develop in a way that pleases us. Mother and cub appear perfectly panda, both physically and behaviorally.
And we wouldn’t have it any other way.
