If you're looking for more science/nature cams, EarthCam for Kids has a bunch. See: http://www.earthcamforkids.com/ Of course, be careful. This is part of the Earthcam service which has many more sources. Make sure to review before linking. http://www.earthcam.com/ Not found in the EarthCam for Kids directory were several of the animalcams here in DC at the National Zoo.
