I just thought I'd share:
I am a volunteer at the Vancouver Aquarium and have been watching over the Aquarium's 21-year-old Aurora on the nightshift as Aurora was pregnant with her third calf.
She just had her baby today. Unfortunately I was not there to see it happen, but I will spend the night at the Aquarium tomorrow.
You can see Aurora and her calf swim live here: http://www.vanaqua.org/belugacam/ and there is a link on that page to a couple of videos of the birth itself.
There is not a whole lot known about belugas and they are difficult to study in the wild. This is a pretty unique opportunity to learn about them. And it's quiet in the Aquarium at night...
