eBird

eBird offers innovative online tools for birders to keep track of their own lists and contribute their bird sightings for use in science and conservation. Birders, scientists, and conservationists can collect, manage, and store their observations in eBird’s globally accessible database—or use graphing, mapping, and analysis tools to better understand patterns of bird occurrence and the environmental and human factors that influence them. This real-time data resource produces millions of observations per year from across the hemisphere. eBird is a joint project of the Cornell Lab of Ornithology and National Audubon Society.
