If you're an amateur naturalist (or just like taking pictures of animals), check out this new site called noah . It's a citizen science project that allows anyone with the noah iPhone app to upload images and locations of animals they see. The result, they hope, is a robust species list that works both as a field guide and a useful tool for science. They're in "beta" mode now and the data thin and a little messy, but it'll be an interesting project to watch.There are some similar projects out there already. If you're exclusively into birds, check out eBird , a bird-only site run by Audubon and the Cornell Lab of Ornithology. There's also Edward O. Wilson's Encyclopedia of Life , which also aims to be an exhaustive online catalog of life on earth but is less "citizen science" and more "scientist science" than noah.
