Ornithological citizen science

eBird is an online database of bird observations providing scientists, researchers and amateur naturalists with real-time data about bird distribution and abundance. Originally restricted to sightings from the Western Hemisphere, the project expanded to include New Zealand in 2008, and to cover the whole world in June 2010. eBird has been described as an ambitious example of enlisting amateurs to gather data on biodiversity for use in science.

Avibase is an online taxonomic database that organizes bird taxonomic and distribution data globally. The database relies on the notion of taxonomic concepts rather than taxonomic names. Avibase incorporates and organizes taxonomic data from the main avian taxonomic publishers (The Clements Checklist of Birds of the World, Handbook of the Birds of the World, BirdLife International, IOC Checklist and the Howard and Moore Complete Checklist of the Birds of the World) and other regional sources (e.g. all editions of the American Ornithological Society Checklist of North American Birds since 1886)
