This is the initial page in a guide that allows you to identify sounds made by European birds. As you step through the guide, you will be asked whether the sound was simple or complex, musical or harsh, etc. At each point, the choices include a set of choices of particular sound attributes. For each of these choices, a list of bird sounds that conform to this description is given. If you select one of these from the list, and click on the button labelled "Select bird" you will be presented with a page with a URL pointer to a sound file of that bird, and a text description of the sound you will hear. The sounds and songs that form the basis of this identification guide are Alberto Masi's European bird songs.
At each point in the key, select the choice that most nearly characterizes the sound or song you heard. If you change your mind, navigational choices at the top of the page allow you to backtrack to particular choices you made. There is also a more complete discussion of the guide available, with some discussion of the terms used to characterize the songs.
