The service from Cornell University's Lab of Ornithology provides descriptive information about bird species to support bird watchers and biological researchers. Along with related services Avian Knowledge Network and Neotropical Birds Online, it gives free access to authoritative information about individual species. Also available is information about bird populations for specific locations, including a mapping interface.
API methods support information retrieval by species or location. Applications can also log sightings of particular species and tracking of individual contributors' sightings. The provider invites birders to share their sightings across the eBird community for use by hobbyists, science research, and conservation efforts.
