A 12-year-old near Vancouver, British Columbia, recently sighted an American robin and submitted his finding to eBird – becoming the 100 millionth observation.
Launched in 2002 by the Cornell Lab of Ornithology and Audubon, eBird is an online application for birders to record their checklists, and for scientists to collect a massive database of citizen-science observations about bird abundance and distribution. Over the past 10 years, more than 93,000 observers have submitted checklists with observations on about 9,500 of the planet’s 10,157 species of birds. Altogether, eBird’s 100 million observations equal 860 years of fieldwork.
So far, eBird has received 7.1 million checklists from 1 million locations.
The most reported species is the Mourning Dove with almost 2 million observations.
