The Warbler Guide funktioniert nicht

The Warbler Guide App is the perfect companion to Princeton’s revolutionary and widely acclaimed book The Warbler Guide, by Tom Stephenson and Scott Whittle.  Whether for study or field use, this innovative app delivers the full power of The Warbler Guide in your pocket—plus unique new app-only features.  Tom Stephenson’s articles and photos have appeared in Birding and Bird Watcher’s Digest, at Surf-birds. com, and in the Handbook of the Birds of the World.  Scott Whittle lives in Cape May, New Jersey, and has twenty years of experience as a professional photographer and educator.  Exciting new 3D graphics enable you to view a bird from the exact angle you see it in the field.  And the whole range of warbler songs is easily played, compared, and filtered.  A musician, he has had several Grammy and Academy Award winners as clients, and was director of technology at Roland Corporation.  The app allows you to identify birds by view or song, quickly and intuitively.  He has guided groups across the United States and Asia.  He holds an MFA in photography from the School of Visual Arts in New York, is a fellow of the MacDowell Colony, and is a onetime New York State Big Year record holder.
