eBird is a citizen science project created by the Cornell Lab of Ornithology that allows birdwatchers to record and share their bird observations online. Users can submit data about the species they see, the number of individuals, and the location of their sightings. This information helps researchers track bird populations and migration patterns. The platform is accessible to everyone, from casual birdwatchers to professional ornithologists. By contributing to eBird, participants help build a global database that supports conservation efforts and enhances our understanding of avian ecology.
