Mei Xiang, our local panda here in Washington, DC, is experiencing elevated hormone levels that may indicate pregnancy. Here's hoping. Young Tai Shan is scheduled to be handed back to the Red Chinese soon, so we could use a new baby panda. I'm a bit puzzled that the zoo can't determine this with a greater degree of certainty. "There's no reliable pregnancy test for pandas," says the article, which backs up other news accounts I've read. But why can't they use a panda ultrasound and look around?

Photo by me and, no, I'm not sure whether that's Mei Xiang or Tian Tian.
