Since I have never used the IBird or Bird Jam software on my Ipod I really don’t know the depth of these products. My impression is that they are really great tools. I have the Stoakes CDs on my Ipod. I have taken all the tracks and have edited them to remove the intro with CD Wave, it is really easy to do but a very time consuming process (a good winter project). I also have a complete photo library of every North American bird species (of course I downloaded most of these and don’t have permission to share them). I really have never used the photo library in the field but I do use the other recordings through a game call speaker. I think that the best feature of this system is that I am able to create a playlists of bird vocalizations and select shuffle for this playlist so that I can use it as a study tool to learn and practice vocal identification. It has been a wonderful learning device. Like I say I have never used the marketed software packages and they may have this same capability.
