Baby Giant Panda! What a cutie!

WASHINGTON — A newborn panda at the National Zoo in the US capital is healthy and "very active, very vibrant and very pink," officials said Sunday.

The good news comes a day after the cub's twin was stillborn.

Keepers were able to briefly examine the surviving sibling -- born Friday -- just before 9am, then return it to its mother Mei Xiang.

The sex and paternity of the tiny offspring, conceived via artificial insemination, will remain a mystery for two to three weeks until results of genetic testing come in.
