The phrase "tracking" usually conjures up images of biologists hacking through the bush, using footprints or radio collars to find animals. But a team of Smithsonian scientist tracks animals another way: using an army of volunteer citizen scientists and camera-traps in a revolutionary program called...

This panda update was written by keeper Nicole MacCorkle. We still don't know if Mei Xiang is pregnant or pseudopregnant.
