Knowledge of an animal's distribution is vital for any biologist who wishes to understand its habitat requirements or assess population changes with a view to management, either for control or conservation. In 1977 the Royal Australasian Ornithologists Union launched a five year scheme to map the distribution of all bird species in the country. This was a courageous act in a country the size of Australia, which has vast areas hundreds of miles from the nearest ornithologist. The large number of bird species to be identified would have provided a daunting task for all but the most competent ornithologist. Australia has 25 rap tors compared with our two, and more than 50 species of honeyeater where we have only three. The Atlas of Australian Birds presents the data gathered by over 3,000 contributors from the 812 one-degree squares on the Australian continent. The final product is an impressive tribute to these people and to the administrators, researchers and others who supported the scheme financially. This Atlas must rank as one of the major contributions to Australian ornithology.The lengthy introduction is essential to describe the background to the Atlas and the methods of recording, the vetting and processing of these records through to the computer storage and analyses of the data. Of particular interest to scientific organisations in New Zealand is the funding which the scheme obtained from federal and state government organisations. The RAOU was therefore able to retain its autonomy and use this financial assistance to employ its own staff. Details of what data were requested from observers and how they were to record it are relevant to the natural sciences in New Zealand. Comparisons may be drawn with the techniques applied to our own atlas of bird distribution, and I am sure lessons can be learnt that will benefit any future repeat of this exercise on either side of the Tasman. Other survey work which may be planned by our Biological Resources Centre would also benefit from a study of these methods. For example, I question the wisdom of allowing observers to submit their records already coded for punching. Errors will inevitably occur during this operation, and, because the original longhand records have not been retained, it has not been possible to assess the accuracy. Neither will researchers in the future be able to check on records that they may doubt. The Introduction also contains analyses of the data which assist the reader to interpret the distribution maps. As could be expected, a greater observer effort (record cards per square) was made in areas closer to civilisation; but, surprisingly, more squares were visited during the winter months than any other season.
