Pandas Play Peek-a-boo

Yun Zi

Many of our blog readers have commented in recent weeks that they are concerned that they haven’t seen giant panda Yun Zi on Panda Cam or in person. Some have expressed concern about his apparent disappearance. I thought I would take a moment to explain some of the factors contributing to his absence and to reassure you that Yun Zi is just fine.

As you know, the San Diego Zoo has new HD cameras that have vastly improved your Panda Cam viewing experience. No more grainy, foggy, or blurry images online. Instead, we have clear, enlarged images that help you get a better feel for the pandas and their enclosures. However, not every one of our facility’s 30-odd cameras was replaced with the HD system. Several of our areas are still serviced by our old, standard cameras. However, the old system is not compatible with our new HD service. That means that when a bear is in an area with an old camera, he or she will not be visible on the Panda Cam.

So why not simply rotate a bear outside where he is accessible both to the visiting public and the Panda Cam? We would do that, under typical circumstances. However, we have a few other factors at play that are influencing our decisions about panda placement. For one, the panda gift shop is being rebuilt. During the construction, we are watching the bears very closely to document their response to this disturbance and ensure the welfare of our animals throughout the process. We are in a current holding pattern of minimizing all other transitions for the bears to further reduce any potential stressors. That means we are keeping animal rotations to an absolute minimum so long as the bears seem comfortable.

We are also creeping close to the breeding season for our adults. The main viewing exhibits are the home base for Bai Yun and Gao Gao once estrus begins, and the place where any breeding would occur if the two were inclined to copulate. Bai Yun has been doing a little scent marking lately, although she is likely weeks away from beginning her estrus. Even so, this is just another factor in play when we make determinations about which bear will be in any given spot on any given day.

Currently, Yun Zi is being housed in an area with the old cameras, which is why you haven’t seen him. He spends his days with access to behind-the-scenes bedrooms and off-exhibit outdoor areas, including our “classroom” exhibits. If he is high in one of his trees, a Zoo guest can catch a glimpse of him when strolling past the facility or riding the moving walkway to the landing near Owens Aviary. If Yun Zi is on the ground or in his bedroom, all areas fitted with older cameras, he is not visible to the public.

But even when he is out of sight, he is clearly not out of mind for our readers. You’ll have to be content to know that we are taking great care of our young male, and he is happy and healthy and content. Soon enough, when the time is right, he’ll be back in view in the exhibits. And if Bai Yun mates again this spring, she will eventually be pulled off exhibit for an extended period as we watch her for signs of pregnancy. Yun Zi and Gao Gao will be our panda ambassadors, but many will ask: when is Bai Yun coming back on exhibit?
