eBird

eBird is an online database sharing knowledge about observations, distribution and abundance of birds among recreational and professional birders around the globe. When launched by the Cornell Lab of Ornithology and the National Audubon Society in 2002, the platform was restricted to sightings in the Western Hemisphere. In 2008, the database expanded to include observations from New Zealand and again extended their scope to a global coverage in 2010, evolving into a collective enterprise. Today, eBird is the worldwide largest citizen science project on biodiversity research with more than 100 million registered bird sightings each year, collaborating with hundreds of partner groups for regional data entry portals, data review, engagement, and local impact on the conservation of birds and their habitats (Sullivan et al., 2014).
