This was posted on a birding loop I'm a member of so thought I would share in case there are any folks who are wanting to work on their bird identification by song skills.
Bird Song Defined Decoded Describedby Ernie Jardine
No superficial re-telling of a bird's song! This is a thorough, "teaching-oriented" guide to learning bird song. The author organizes the songs of over 200 birds according to a practical "system", which allows a birder to "access" and identify a mystery song, often right in the field while the bird is singing. More importantly each song is described in detail by its overall make-up and quality, and the nuances and progress of the notes within each is clearly explained as well as illustrated. Songs are also defined and organized according to specific habitats, as well as according to groupings with similar-sounding deliveries. Hundreds of original recordings (available on the author's website) complement and amplify what is being explained in each section of the book. Alternate songs, flight songs, and calls are included, as well as information on habitat, nesting, and summer and winter ranges. This book will be welcomed by the birder and the non-birder alike, by anyone trying to learn and understand more about bird song. (source Amazon.com)
