eBird is the world's largest birding community, offering birdwatchers a platform to keep track of their bird lists, photos, and sounds, as well as to explore the latest sightings from around the world. With a goal to gather and share unique knowledge and experiences of every birdwatcher, eBird compiles checklists of birds to support data-driven approaches to science, conservation, and education. eBird also provides tools that make birding more rewarding, such as managing lists, photos, and audio recordings, real-time maps of species distribution, and alerts for species sightings.

With over 100 million bird sightings contributed annually, eBird is one of the world’s largest biodiversity-related science projects, managed by the Cornell Lab of Ornithology. The platform collaborates with hundreds of partner organizations, regional experts, and users worldwide to document bird distribution, abundance, habitat use, and trends. eBird data is freely accessible and has been used in numerous conservation decisions, student projects, and bird research worldwide
