The progress of nesting is indicated by the proportion of drakes 
which are seen without hens, the latter presumably being hidden on their nests. 
Table VI shows this ratio from 1951 through 1955. The early season of 1955 
was reflected in a very high percentage of lone males, indicating that nesting 
was well underway.
