"''The Field Guide to the Birds of Australia'' was first published in 1980, after more than fifteen years in the making. While it has continued to evolve through numerous reprints and revised editions, taking in new information, taxonomic changes, and changes in the way information has been presented, the voice throughout has remained resolutely that of its author, Graham Pizzey.

"Following the death of Graham, our husband and father, in late 2001 it soon became clear that we were all keen to see the Guide continue. After all, the entire family was there at its inception and development: travelling to various corners of the continent as Graham took countless photographs and recorded observations in the field. An article in the ''Herald'' in July 1967 shows the three Pizzey children sprawled on the living-room floor, poring over a map as we traced the journey we were about to make up through the Centre and down the west coast. The ‘Big Trip’ was to form the basis of the research for the first edition of the Guide, and was to give us an indelible appreciation of the natural world. And we’ve been involved in various ways ever since: looking at proofs, being asked for an opinion on an illustration or cover, or listening to an attempt to capture the call of a bird on paper. Responsible for providing his own children with an extraordinary childhood, this Guide is now being enjoyed by Graham’s small grandchildren. Its continuing relevance underpins our desire to see it remains in print, updated and augmented regularly."〔Pizzey & Knight (2003), p.xiv.〕
