[H2] Participatory Science
Our participatory-science projects engage hundreds of thousands of people in recording bird observations – whether in backyards, city streets, or remote forests. Scientists analyze data submitted through our projects to understand how birds are affected by environmental changes. Whatever captures your fancy, there’s a participatory-science project that can make it more meaningful.
