AUTOMATED WATERFOWL CENSUS Dr. D. Bajzak Associate Professor of Engineering Memorial University of Newfoundland St. John’s, Newfoundland INTRODUCTION The most Important uses of photo interpretation in wildlife management are the censusing of animal popula tions and the mapping and evaluation of wildlife habitat. In some directions satisfactory photographic techniques have been deveoped, in others much remains to be done. Among the latter is the need to develop techniques in photographing large number of waterfowl and a rapid and reasonably accurate method for counting large numbers of individuals on the photographs taken. From 1967 serious attempts were made by the writer and personnel of the Eastern Region of the Canadian Wild life Service to develop aerial photographic techniques for the census of game birds. Large flocks of birds were photographed through the porthole of an aircraft. Then these photos were used to count the birds, if possible by classes. Visual observation of some photographic speci mens indicated that at least three, but possible four classes of Eider ducks, Somateria mollissima , can be distinguished. This suggested that with the use of a scanning microdensito meter the class distinction would be more objective. In addition to this, the counting procedure could be automated. While the development of the aerial photographic proce dure is relatively easy, the development of an automatic counting procedure is very difficult and time consuming task. The bird images first have to be digitized, then valid patterns have to be established, finally bird images have to be separated by comparing them to pre-established patterns. In 1971 research work was initiated by the author in the field of automated waterfowl census using aerial photo graphy and microdensitometry. From 1971 to 197^ this research was supported by the Canadian National Research Council which is acknowledged.
