Merlin Bird ID by Cornell Lab

Merlin Bird ID helps users identify birds by answering simple questions, uploading photos, recording bird songs, or exploring birds in a specific region. It benefits bird watchers by providing accurate identifications and enhancing birding knowledge.

The app uses machine learning models trained on millions of photos and sounds from eBird to deliver photo and sound-based identifications. It also offers expert ID tips, range maps, and personalized bird lists based on location.

Merlin is used by bird watchers, educators, and citizen scientists worldwide to identify birds across continents, track sightings, and contribute data to global bird monitoring efforts.
