In 1998, the Cornell Lab of Ornithology and the National Audubon Society launched the Great Backyard Bird Count, the first online citizen project to collect data on wild birds and to display results in near real time. Canada joined the project in 2009, and in 2013 it became a global project — the world's largest biodiversity-related citizen science project.
Each February, for four days, the world comes together to spend time in their favorite places watching and counting as many birds as they can find and reporting their observations to help scientists better understand global bird populations before one of their annual migrations.
This year the Great Backyard Bird Count takes place February 18 to 21. If you would like to participate, click the button below for more information.
