The Canvasback, Common Goldeneye, and Bufflehead in Arctic Alaska

Abstract

surface water (Bartholomew and Cade, op. cit.) it would not be surprising if its salt tolerance and its ability to discriminate between salt solutions of different concentrations actually function in promoting the biological success of the species. Whether this is actually the case will have to be shown by the results of future field studies. Thanks are extended to R. T. Sanders for suggestions during the course of the study, and to James L. Woodson for care and weighing of the birds in my absence, and to both the above, but especially to K. L. Dixon, for criticism of the manuscript.
