Binding tight and solid. The purpose of this book, as titled, is to exist as a photo reference guide. I have found it to be nearly perfectly sufficient. It covers the majority of species kept in captivity, including rarer birds, but there was a noticeable lack in some places, such as in regard to several species missing from the section "Parrotlets", which is peculiar because the guide is extensive yet the missing species of parrotlets have been kept in captivity since before the date of publication. The pictures themselves are acceptable, though some tones such as orange are washed out. For each species profile the book provides a color photograph with the following information: length, weight, origin, status, aviculture, accommodation, diet, clutch size, incubation, young in nest, sexual dimorphism, etc. , etc. , etc. Mrs Low has been a prolific author who has produced several species specific books for birds like macaws, caiques, lories and others. If the reader requires detailed information that would be the place to look rather than this text. It is important to note that this covers parrots in aviculture, not obscure birds that are kept wild like the kakapo--it is not a field guide. EB; 9.4 X 6.5 X 1.4 inches; 288 pages.
