eBird and International Migratory Bird Day

eBird has revolutionized the way that birders report and access information about birds. Launched in 2002 by the Cornell Lab of Ornithology and National Audubon Society, eBird provides information on bird abundance and distribution at a variety of spatial and temporal scales.
eBird’s goal is to gather, archive and disseminate the vast numbers of bird observations made each year by bird watchers. It is amassing one of the largest and fastest growing biodiversity data resources in existence. For example, in 2006, participants reported more than 4.3 million bird observations across North America!
The observations of each participant join those of others in an international network of eBird users. eBird then shares these observations with a global community of educators, land managers, ornithologists, and conservation biologists. In time these data will become the foundation for a better understanding of bird distribution across the western hemisphere and beyond.
