Features include: • A new easy to navigate menu system on iPhone. • A new grid view with larger thumbnails. • Display species names in English, French, Spanish and Latin (Scientific). • Search on banding code to quickly find a species. • Over 2700 calls/songs covering most species. • Compare 2 species side by side. • Apply a location (US State or Canadian Province) to narrow down the list of birds. • When a location has been selected, a status icon will appear next to each species in that location indicating whether it is Common, Uncommon, Scarce, Rare or Vagrant. • Detailed information in the species description including location status by month. • A similar species feature which shows all related birds. • A vastly improved Smart Search with refined search criteria: Status and by month (when a location is selected), Bird habits, Bird Type, Bird Size, Body Shape, Color and Pattern. • Keep a personal list (My List) of species seen and backup to iCloud/other cloud service. • Build a custom sharable (as csv) and searchable (in Smart Search) species list using the new My Tags feature. • Sort My List taxonomically.
