National Geographic has a lot of cool webcams.
Pete's Pond in Africa is my favorite. (previously
) It's up and running again for its third season till mid-December, the end of the dry season. Best viewing times are 4-8 PM EST and
12-4 AM EST. Lots of highlights
can be found at youtube, of course.
NG also provides the Seal Cam
from Año Nuevo, California,
Bald Eagle Cam
from Maine, the Kakadu Cam
from Australia and and the Polar Bear Cam
from Canada. There are a lot of grizzly bears fishing right now on the Bear Cam
from Alaska, but the Crane Cam
from Nebraska is down right now. To view these cams you have to sit through a short commercial at first, but after that it's all live wildlife goodness.
There are also very active forums
where people share their screencaps and vicarious adventures.
