The anticipation had been mounting on Saturday at the San Diego Zoo’s Giant Panda Research Station, because Bai Yun had not made an excursion from the den since Thursday evening. We knew she was due for a trip out soon. And we were anxious for a good look at her youngster, hoping to see progress in its development over the last 36 hours.
Then, at about 2:37 p.m., Bai Yun indulged us. She first hydrated with a long drink. Then she headed out to her sunroom for a quick snack of bamboo. She only had time for a few bites, but since this was the first time she had eaten since before the birth, we wouldn’t have expected her to settle in for a lengthy feast. Finally she finished up with defecation and urination, pulling extra bamboo about her to make her “bamboo skirt.”We aren’t totally certain what the significance of the bamboo skirt might be. It’s probably a way to hide the site of her waste and mute the scent of it as well. We might imagine that could be important for a wild panda mother that is taking pains to hide her den and her cub from the outside world. At this stage of the game, even when she leaves the den she would not be traveling far, so anything she can do to hide evidence of her presence might be advantageous.
We did get that long look at the cub we were hoping for. And boy, does this cub look good. The belly is rounder, and the limbs look stockier. The neck looks a little thicker. And the body is covered by a coat of white fur that is obviously more dense than before. The physical markers of healthy development are all over this cub.
What’s more, the cub was more tolerant of Bai Yun’s departure from the den. Sure, it squawked its disapproval from time to time, but for most of Momma’s absence the little one bobbed its head and appeared to be rather patiently waiting for her return. As the moment wore on, it appeared to be tiring a bit and put its head down on the floor for a breath or two to rest.
After an absence of nearly six minutes, Bai Yun returned to the den. She immediately scooped up her cub, placed it near her teats and began licking the youngster in a soothing manner. In a flash the cub was thoroughly contented.
We’d expect nothing less from Bai Yun!
