I was recently recommended this website
by a keen local naturalist. It is run by the Open University and is a great place to upload photos of wildlife and have experts identify them for you. Not only that, but you gain 'social points' the more you use the site and
build up your reputation as a naturalist when you identify other people's sightings. Because of this, there is a real incentive to use the site and to be honest it is quite addictive. All plant and animal groups are well represented including invertebrates and birds, so give it a whirl!
