Officials at the National Zoo in Washington, DC are mourning the death of a panda cub born just a over a week ago.
The four ounce cub was found dead in its den Sunday. Zoo officials immediately performed a necropsy and have some preliminary results, including the finding that the cub was likely a female.
Meanwhile, zoo officials are keeping an eye on the the cub's mother Mei Xiang using the web cam.
"Sadly we witnessed her cradling an object for most of the night. This is the same behavior she demonstrated right before the cub was born so we think this is her natural mothering instinct," said Dennis Kelly, director of the National Zoo.
A full report on the cause of death is expected in about two weeks.
