Last night, a little after 9, Bai Yun made her first den departure. She stepped out briefly to get a drink of water. Although female pandas generally fast for several days after the birth of their cub, it’s not unusual for them to need a drink of water a day or two postpartum.
We are happy to see that Bai Yun is looking after her own needs; it will be critical to her success in rearing this cub past the first few crucial days of life. Bai Yun is no newbie to the process of cub rearing, and with her most recent cubs she showed us how she has been able to walk the line between providing excellent care to herself while maintaining excellent care of her cub.
Although Bai Yun was out of the den for only about a minute, her absence from the den afforded us the first good look at her youngster. What we saw is very encouraging. The cub was extremely vocal, registering its complaint over Mother’s absence. To us, that indicates good vigor and a proper behavioral response to the cool air and loss of contact with Mom. The cub was wiggling all over the floor, indicating good strength and energy. And the cub had a nice, round belly, indicating that Bai Yun is providing plenty of milk.
We are not out of the woods yet, but thus far everything looks great in the den.
