Hundreds of thousands of people around the world contribute bird observations to the Cornell Lab of Ornithology each year, gathering data on a scale once unimaginable. Scientists use these data to reveal how birds are affected by habitat loss, pollution, disease, climate, and other environmental changes. Your participation will help us trace bird migration, nesting success, and changes in bird numbers through time. These insights inform conservation plans and key actions to protect birds and habitats. Find a project that’s right for you!
If you enjoy watching birds, contribute your passion to help science and conservation, whether by watching birds at your feeders, monitoring nests, or sharing your sightings any time, anywhere. We welcome your participation! Please join our community by getting started today.
