This incredible DVD includes 2,500 color photos, 700 range maps and songs for 653 species. 275 video clips showing bird behavior are also included. This DVD can help you identify unfamiliar birds. Simply select the color, size, habitat, location or sound of your bird and the Identification Wizard will show you everything that matches your description!

Also included are 700 quizzes arranged into "Birding Hot Spots", "Christmas Bird Counts", Favorite Birds" and more. Set the level at Easy or crank it all the way up to Difficult. Select Multiple Choice, Fill-in-the-blank, Flash Card or "Pick One" quizzes. This DVD also includes a listing and recordkeeping program to help you remember the birds you have seen.

With version 4, you can also share Custom Lists with your friends, download songs and photos to an iPod for your own personal use and add your own comments for each bird. New colorful icons make it very easy to use the DVD.

New features in version 4 include detailed range maps showing the Central and South American ranges, Banding Codes and an ID Wizard Photo galley that displays not just males in breeding plumage, but females or immatures as well.
