Yesterday was the first day of spring. In celebration of all the new life and growth that comes with the season, use this community-sharing site which lets all the world's sharp-eyed naturalists, including school-age students, record their observations of the outdoor world. When entering observations, users can search the site's taxonomy list for a species name, submit data such as place and time observed, and contribute photos through Flickr or Picassa. In addition, users can search the site by drilling through taxonomies, filtering by color and/or place, or by searching by the name of a species.
