Certificate arrived!

A link to a YouTube clip purportedly showing "the birth" of the first cub has been posted. The 4.5 minute clip shows the same black fur, with snowflakes, as before, but moving around some. Most of the "action" seems to be just off the field of view of the camera.

For the clip, turning sound up would be recommended, as the noises made by the cub are for the most part more informative than what can be seen.

The "title" at the movie does confirm the birth occured on 22 Jan.
