Serum proteins from nine subspecies of Canada Geese (Brunta canadensis) were analyzed through the use of column and slab acrylamide electrophoresis. Variation was minimal within a subspecies, although all the subspecies were closely related. B. c. leucopareia appeared to be the most distinct subspecies, while maxima and moffitti were the most similar. Our preliminary findings suggest that the electrophoresis techniques are sensitive enough to identify some of the subspecies; however, baseline data from breeding ranges of all subspecies are required.
