I choose this guidebook by checking from books' update version and customer comments, that seem to mentioned it on a positive way. That's why I had highly expect for its quality, the picture in this book is large & clear, has identified arrow for each species that help a lot when using in the field, information about subspecies in Australia, detail of biomes, migration, breeding season is excellence, maps is o.k. But many necessarily details are overlooked;
-Firstly, this book doesn't focus on Australian islands such as, Load Howe, Christmas, has only species list in these areas, which no picture and identified information.
-Unacceptable weakness are, no picture for some new-discovered species that able to identified by your bare-eye and some distinctive subspecies (like, Cape York brush-turkey), not show for some important plumage pictures; like, male of southern cassowary, adult plumage of royal penguin
-There has some line drawing pictures on opposite of species plate as supplement part, but not much help because it's not painting picture.
Sadly, I ever seen other Australian bird guide before, although it is not latest information update but it has more cover information than this guide. Dear tourists who want to have a backpack traveling in Australia and its territories, and looking for a cover information bird guide, please thinking before you buy this book.
