Note.--Coverage during the period was not comparable and 
the data were adjusted, using 1959 and 1955 as base years. 
It was assumed that areas where comparable surveys were 
conducted provided an accurate measure of the percentage 
change between 2 consecutive years. On this basis, popula- 
tion estimates were calculated backward and forward from 
the base years. The 1962 figures are based upon only ob- 
served birds and are not adjusted. 
* Includes 37,549 miscellaneous and unidentified birds.
