This is an excellent book for anyone, age regardless, who hasn't a clue about which bird song they are listening to.The illustrations are lovely, the bird song clear and distinct, the information useful. I bought it for my 2 year old grandson. The pages are made of thick material so won't get ruined easily at all. I liked the book so much I bought another for my friend (65 year old who confessed she couldn't tell one bird song from another), and another for a 5 year old. I am about to order a fourth one, for me, and no doubt I will buy more. I just hope the authors will provide a second volume because this is such an easy and pleasing way to learn bird song and there are a great number of other common garden birds which should be included: the magpie, the sparrow, the cuckoo, to name but a few.
