About
The Cornell Lab of Ornithology is a globally recognized center for the study, appreciation, and conservation of birds. Powered by science, technology, and a community of millions of contributors worldwide, it bridges professional research and everyday birding through a suite of AI-enhanced digital tools and platforms. Merlin Bird ID uses machine learning and computer vision to help users identify birds by photo or sound in seconds. eBird is the world's largest citizen science database, collecting hundreds of millions of bird observations that fuel real-time Status and Trend Maps used by scientists and conservationists. The Macaulay Library is the world's largest archive of wildlife audio, video, and photo recordings, freely accessible for research and education. Bird Academy offers online courses for birders of all levels, transforming how people understand avian biology and behavior. Additional participatory science projects—including NestWatch, Project FeederWatch, and Celebrate Urban Birds—let anyone contribute valuable data from their own backyard. The Lab's work spans education (K–12 curricula, college resources, Young Birders Network), media (Bird Cams streaming live wildlife footage globally), and conservation advocacy. Its research informs policy and on-the-ground efforts to protect endangered species and habitats worldwide. Whether you're a casual backyard birder, a student, a researcher, or a conservation professional, the Cornell Lab provides free, science-backed resources and AI tools to deepen engagement with the natural world.
