Book and two audio CDs for GBP29.95. Published by The Sound Approach
This innovative book and accompanying CDs will change the way you think abo=
ut bird song forever. Mark Constantine decrypts the sonogram into an intell=
igible aid for birders. Exactly how Scottish an accent does a Scottish Cros=
sbill have? Can you sex a Chiffchaff by call? Dave Gosney reviewed "The boo=
k is a terrific read and deserves to be bought by any birders who want to t=
ake their sound identification a whole leap further forward. I can't rememb=
er the last time I was so impressed, entertained and enlightened by a birdi=
ng product. Birders everywhere should get this." You can read Dave's full r=
