Guide to North American Bird Songs and Sounds
Remarkable in that it allows you to search by how the bird song sounds -- single note, double note, or complex song -- and then listen to the audio files.
This guide will help you identify songs and sounds of North American birds. As you step through the guide, you will be asked whether the sound was simple or complex, musical or harsh, etc, a set of choices of sound attributes. For each choice, a list of birds whose sounds conform to this description is given. If you select one of these and click the "Go" button, you will see a pointer to a sound file of that bird, a text description of the sound you will hear, and a sonogram of the sound.
