The first point for Amazon.com customers is to note that this CD and book was produced with the British market in mind. Most of the species featured will be found in Britain, with a few that occur elsewhere in Europe included for comparison - or in the hope you can spot that rarity. (Incidentally, the CD does not include Black-headed Bunting used on the book cover.) For serious UK birders, this is a useful product that draws attention to features of calls that will improve your field skills. Less serious birders might think this is anorak territory. Many of the sound clips are short, deliberately so in order to aid comparisons. This is not a disk to compare with bird song recordings that folk will listen to just for pleasure, but for many birders the calls featured will be evocative of personal experiences in the field.
Many CD systematic bird guides now include recordings of calls, or they occur incidentally in video clips. This CD will help you make use of such resources and is excellent value. I give four stars for being different in a market saturated with potboiler field guides.
