2017 will mark the 15 year anniversary of eBird. In just a decade-and-a-half, the bird checklists that you have shared have helped make eBird the largest citizen science biodiversity project in the world. More than 1/3 million eBirders have submitted 370 million bird sightings, representing 10,313 species from every country in the world. We are continually humbled by the amazing power and passion of the birding community, and have nothing but excitement as we look to the future of what we can do together. As we compile this list of eBird’s achievements in 2016, we are reminded that these are all truly your achievements. It is your contributions that power this knowledge engine. Every time you go out and keep a list of birds you see, you’re making a real contribution to our understanding of the world’s ever-changing avian biodiversity.
