Now on Sale!!! The most popular printed field guide to North American birds is now available in its entirety on the iPhone and iPad! We have taken the simplicity and ease-of-use that you have enjoyed on your iPhone/iPod Touch and expanded and redesigned the layout (not simply “stretching” it) to take full advantage of the larger screen area of the iPad while still being the same app that runs on the iPhone/iPod Touch. The Sibley Guide to Birds has become the most popular and fastest selling printed guide to birds as well as the most comprehensive and authoritative guide to North American Birds: Over 6600 images. Every species is shown perched and in flight from above and below. Shows every major seasonal, age, and male/female variation. Detailed coverage of subspecies and regional variations. Detailed maps showing not just winter and summer range but also migration and rare occurrence. Detailed descriptions of songs and calls, comparing similar species measurements of length, wingspan, and weight for every species. Now all of that information is available in an easy-to-navigate portable format on the iPhone/iPad. In addition, this version of the app also includes: ● Swipe to move to the next or previous species. ● One-tap enlargement of images and rotating the device expands images further. ● Over 2300 carefully-selected and edited sound recordings. Nearly all species are represented with multiple examples showing the range of vocalizations. ● The ability to compare any two images, maps, or sounds, side by side on the screen. ● The ability to filter by state/province, so that you see only the species likely to occur in your location, and to further reduce the possibilities to the most common birds in that area. ● The ability to search by distinguishing features such as size, prominent colors, habits, and group. ● A basic personal species list* that stores your sightings saved to the device with the ability to export the list using email or iTunes file sharing. *Uninstalling/reinstalling the program will result in the loss of your list, it is recommended that you keep your own backup (master list) separate from the application.
