 eBird:
A joint project of ZEISS, the Cornell Lab of Ornithology and National Audubon, eBird provides on-line listing for birders. Sightings entered become part of a world-wide data base of bird numbers and distribution that is available to researchers and birders alike. One of the most important Citizen Science projects of our time!
