The San Diego Zoo’s director of reproductive physiology as been capturing thermal images of our adult female giant panda, Bai Yun, as we monitor a possible pregnancy. Here’s her latest report!
Here are the two latest thermal images from Bai Yun. In each image, two indistinct red 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.
