After a great introduction to the iPhone version of Sibley's ENTIRE field guide by Craig Caldwell, I found that it has also been ported over to Droid phones as well. For $19.95, you get the entire Sibley North American Birds, all the text, all the artwork, plus the songs and calls (with regional variations). An amazing app, and very useful !
