New Software: Thayer's Guide to Birds of North America

Back in the old days, Peterson and Golden printed field guides were the top choice for helping identify birds, and they are still the best companions for on-the-trail use. But software is fast surpassing what print can do, especially when it comes to video and audio match-ups. Thayer's Guide to Birds of North America is pretty dazzling in its depth, giving users the ability to identify birds based on color, markings, size, habitat, location or song description. Videos and song sound files can help confirm your ID as you attempt to narrow the choice from among 925 birds seen in the continental U.S. or Canada.  And you can even use the software to keep your bird notes and start a life list. Check out their sample page for the Rose-breasted Grosbeak for a taste of the depth of information.
