The text is probably a direct translation from German. Has some funny expressions, rarely used in English. The information on classification of macaws is out of date. The same goes for the other information in the book. Too often some irrelevant and not so important historical notes are given, like dates of hatching in some zoos from the last century, or first pairing, etc. There is lack of consistence in dealing with the species description. The book is good for its superb photos. It is also maybe the only one to have drawings of the extinct macaw species. Otherwise, ... nay!
