I haven't been to the Philadelphia Zoo in a few years, but they are currently experiencing a baby boom. They have a baby penquin there that is soooooo cute!
Here is a link to see a kind of video/slide show of the baby animals.

Then you'll see a tab for "Television". Click on "Philadelphia Zoo Baby Boom".
You'll probably have to have high speed internet access. I don't know if you'll be able to view it with dial-up.
Enjoy,
