"''The Mallee-Fowl''" is an important work in Australian ornithology. It is the first book for public appraisal of a life history obtained by extensive and methodic research in field and laboratory. Its subject – an extraordinary bird species now moving towards rarity through man's indifference – requires such a public book in support of a major and urgent conservation task revealed. The research was done by Frith during 1951 to 1958, at first in private week-end activity, then as a project of the Wildlife Survey Section (now the Division of Wildlife Research, of which Frith is the Chief) of the Commonwealth Scientific and Industrial Research Organization, with assistance at times by colleagues."〔J.J. (1963).〕

"''The Mallee-Fowl''" is subtitled "''The Bird that Builds an Incubator''". Frith's research was centred on the incubating mound in methodic enquiry of cycle and control; and from that real dominance the enquiry circled out to obtain and collate the remaining substance of life history into relativity, including conservation problems in predation, grazing and clearing for farming. Development of census methods was a necessary corollary. The book bears the research accent by being concerned mainly with life-history detail and gaining of knowledge. It also includes adequate comparison with the other Megapode species, notably the Brush-Turkey and Jungle-Fowl; it speculates briefly on the origin and development of mound incubation in an arid climate; and concludes with a succinct chapter of emphatic appeal for conservation of the Mallee-Fowl."〔J.J.
