The San Diego Zoo has released a new image of a thermal scan of Bai Yun NameBai Yun Chinese Names白云 Stud Number371 Date of Birth1991-Sep- SexFemale Current LocationSan Diego Zoo Born atWOLONG MotherDong Dong - #358 FatherPan Pan - #308 .

"Two indistinct heat structures can be seen, one on either side of her midline, toward the right side of the picture. The arrow-shaped red structure in the middle is her bladder. At this point we can only say these heat signatures are suggestive of two implantation sites."

"We’ll be doing another scan this week, and we’ll continue to watch these heat signatures through the month of July, when we may see them become more distinct, which would indicate growing cubs."
