Raptor ID is a comprehensive identification app developed by HawkWatch International in partnership with the Cornell Lab of Ornithology. It is the first raptor identification app designed for mobile devices and covers North America's 34 species of diurnal raptors. The app features nearly 1000 annotated photos, cutting-edge identification videos, and range maps with links to interactive seasonal eBird maps.

The app's identification content was created by Jerry Liguori and Brian Sullivan, two experts in the field of raptor identification. The content covers plumage, age/sex, and geographic variation of each species, making it an excellent resource for both beginners and seasoned birders. The ID-focused videos show each species in flight from multiple angles and behaviors, including voice-over ID tips from Jerry Liguori. Additionally, the app includes vocalizations for each species and an 'Ask the authors' raptor ID question forum.
