eBird is one of the world’s leading citizen science platforms, developed by the Cornell Lab of Ornithology. Its use actively contributes to global bird knowledge through the participation of thousands of observers who upload checklists, photographs, audio recordings, and videos. All of this material becomes part of the Macaulay Library, one of the largest multimedia biodiversity collections in the world, whose data are used by specialists to generate scientific models and analyze patterns of abundance, distribution, and migration.
In Cuba, Nils serves as an eBird editor and reviewer, a fully volunteer role focused on ensuring the quality and reliability of the information incorporated into the platform. Among his main responsibilities are updating species and regional filters, reviewing and editing “Hot Spots,” and annually updating the list of common bird names used in the country.
His day-to-day work is centered on record validation. eBird operates with a filtering system that detects unusual observations or rare species, automatically generating alerts. These reports are then reviewed, and at that stage contact is established with users to request additional information that helps confirm the validity of the records.
Through this work, Nils has made a significant contribution to strengthening the birdwatching community in Cuba. By generating educational content, providing ongoing guidance, and actively supporting the movement, he has helped increase the number of users on the island and, consequently, improve both the quantity and quality of information available on Cuban avifauna.
