It's twins for the National Zoo's 6-year-old Andean bear, Billie Jean. It's not yet clear, however, when visitors might be able to see the cubs in person. For now, the public will have to log on to the [zoo's live webcam]( http://nationalzoo.si.edu/Animals/Amazonia/AndeanBears/andean-bear-cam.cfm) and hope they're in view.
Zoo staffers say mama bear will stay inside with her cubs for now, and come spring, if they're healthy, the three will head out to their yard.
Andean bears, also called spectacled bears, are one of the world's most endangered bear species. Scientists estimate there's only about 2,000 left in their natural habitat. These cubs are the only surviving Andean cubs in a North American zoo since Billie Jean's first cubs were born in 2010.
The cubs' father had to be euthanized in August after being treated for an aggressive type of cancer.
