This volume, in the Traveller's Wildlife Guides series, successfully fills a gap in available literature on Thailand. Too heavy to be a pocket book, it conversely constitutes a midget encyclopaedia and ideal inflight or sunbed reading. I like the style; the authors start off with Ecotourism instead of slipping in a list of nature reserves at the very end, as though as an after-thought. To test the usefulness of this volume for identification purposes (although no biologist expects every species from so large an area to be packed into a popular guide of this kind), I looked up toads - and there it was, the mustard yellow male river toad (Rana macrotis) I had photographed in my wife's inlaws' kitchen ten days earlier in Eastern Thailand! Being a bit of a butterfly buff, I cast my eyes over the flutterby illustrations, noting that the book's authors used the same common names as I would if submitting a photo to a magazine (most biologists use the scientific names). There's a whole lot I have yet to read but all in all, I love this book and will take it with me along with my DSLR equipment on my frequent visits to Thailand. Just one very minor criticism - a few of the illustrations (including those of the toads!) have not printed out as clearly as one might have liked; doubtless that drawback will be rectified in future editions. By and large the book is a great buy at its price.
