When I saw this in BJs, I couldn't stop pressing the buttons and listening to all the different birds. I discovered so many bird calls that I'd known but never known who was saying them, and could finally connect the two. I also discovered that for the few birds I did know the calls to to begin with, this was a good match up (though I would have chosen differently for catbird and bluejay). It also works a bit as a bird book, with a large illustration of each bird and information. If you've got a feeder or birds around, I'd definitely recommend it. ( )
