Sibley Birds 2nd Edition is a comprehensive bird watching guide that provides detailed information on over 930 North American species. The app includes the artwork from David Sibley's Guide to Birds Second Edition, thorough descriptions, and distribution maps. With features like an easy-to-navigate menu system, a new grid view, and the ability to display species names in English, French, Spanish, and Latin, Sibley Birds 2nd Edition is a must-have for any bird enthusiast.

One of the most impressive aspects of the app is the search function, which allows you to quickly find a species by banding code, location, or other criteria. Additionally, the app includes over 2700 calls/songs covering most species, the ability to compare two species side by side, and a similar species feature that shows all related birds. You can also keep a personal list of species seen and build a custom, sharable species list using the new My Tags feature.
