From the News: Giant Panda Gives Birth to Twins at Zoo Atlanta

Giant Panda Gives Birth to Twins at Zoo Atlanta

At this time, three of the four US zoos to exhibit giant pandas have successfully bred them at least once (everyone's looking at you, Memphis).  That which was once considered impossible - the breeding of pandas in captivity outside of China - is now starting to become almost commonplace.  When I was a kid, there were only two pandas in the US, both at the National Zoo.  Now, we come increasingly close to the possibility of the US being a producer of pandas, a source instead of a sink.
I've got mixed feelings on pandas and the politics associated with them, but that's a subject for another day.  In the meantime, congratulations to Zoo Atlanta for their historic accomplishment.
