e. Remarks: On this important area breeding Canada geese showed an 
increase of 32 percent, while the total fall population increased 
43 percent over 1953. Pairs of breeding ducks increased 44 per- 
cent and the total fall population increased 36 percent over 1953. 
The breeding coot population was down 13 percent, but the fall 
population showed a 12 percent increase over 1953. 
8. Statewide Trend. 
A comparative summary of nesting pairs of waterfowl for the past four 
seasons together with final fall population including young plus resident 
aduits is shown in the following table. These figures for each year have 
been derived from the preceding tables. In almost all cases the figures 
shown for "nesting pairs" are more accurate than those indicating 
"total fall population." The 1952 and 1953 figures are not directly 
comparable with the 1951 figures since basic changes were made in the 
methods of obtaining data from Tule Lake and Lower Klamath refuges 
in 1952,
