The Smithsonian’s National Zoo released photos today of a pair of Andean bear cubs born last December.

Watchers of the National Zoo’s Andean Bear Cub Cam have caught fleeting glimpses of the two new bear cubs born to Billie Jean last week.

Billie Jean, the National Zoo’s Andean bear, gave birth to twins overnight.

Guess what, ursine fans? An ultrasound examination conducted on Billie Jean, the National Zoo’s six-year-old Andean bear, revealed that she is pregnant with a couple of cubs.
