The 1956~57 series data includes a correctipn for differences 
in the percent of active hunters in the different response and final non- 
response groups within the sample contacts made. Analysis of the respon- 
dent groups revealed that small differences occurred in the proportion of 
non-active hunters reported from first versus second response groups. 
The largest discrepancy (Pacific Flyway) resulted in reducing the mean 
seasoral kill by approximately 1.7 percent; the lowest being approximately 
0.1 percent. These corrections were not applied to the 1955-56 data 
tabulated. 
The mean seasonal and daily kill reported for 1954-55 and 
1955-56 in the 1956 Status Report of Waterfowl, Special Scientific Report 
No. 33, related to mean kill per hunter among all active duck hunters, 
goose hunters and active coot hunters respectively rather than to mean 
kill of ducks, geese and coots among all active waterfowl hunters. While 
we believe the mean of a specific universe of hunters, that is, duck, geese, 
or coots, to be a more meaningful statistic of hunter success, it may be 
misinterpreted unless the corresponding universe is also tabulated. Space 
limitations prevent tabulation of these data, therefore, means tabulated 
in this report relate to the mean kill of ducks, geese and coots among all 
active waterfowl hunters and relate to the total number shown each season. 
The use of this mean also facilitates preparation of this report within the 
time limitation under which it is prepared. . 
The final change in presentation as compared to earlier 
Status Reports includes the species totals. The 1956-57 and 1955-56 
totals herein include retrieved totals, whereas species totals in the 1954 
to 1956 Status Reports of Waterfqwl included both retrieved and unretrieved 
totals.
