Ting for birdcalls

I have the Ting-pen along with the book "What flies there?" bought. The Ting-pen is the ideal partner to the book, because you can select the birdsong directly. Who have liked on the CD player, puts a CD, looks the booklet on which track sings the blackbird and selects this track on it? This cumbersome procedure shortens the Ting-pen. The scope of the audio files is very good. It's not just songs but also contain warning and station calls of birds.
For technical aspect would be to say that the download and the pen works very well. Since I want to use the stylus for this book only, I can to a more universal use (such as MP3 players, two books on the Ting etc.) do not say anything. I give 5 points, especially for the concept that is the ideal complement in the case of bird calls.
