From the reviews: The cryptic coloration and secretive lifestyle of owls (Strigiformes) have made their taxonomy problematic for many years. ! Two unique features of this book are the lists of museums holding specimens and the lists of references to illustrations and photographs. ! I was surprised to find an account of an entirely new species of owl in this book. ! In short, Weick's Checklist has many features of a scholarly work and will be useful to specialists and bird illustrators ! . (George Sangster, IBIS, Issue 149, 2007) This is a global list of owl taxa in systematic order by subspecies. Weick is a professional wildlife artist, and amateur ornithologist (with a professional approach). This list is that of a classical museum taxonomist, though selectively talking into account some recent DNA data. ! it makes an invaluable contribution to knowledge of owls and is indispensable to owl biologists, particularly those dealing with taxonomy.
