7. To facilitate interpretation of the data from various 
banding stations the distribution of records is shown on outline maps. 
Where the records are not too voluminous, all recoveries from a par- 
ticular station are mapped; in other instances, where large numbers of 
recoveries are involved from bandings over a period of years, a rep- 
resentative series was selected. 
8. Following is a breakdown of the fall recoveries of 
black ducks which serves as a basis for this report. 
Total Shooting Recoveries - - -----+-- 15,481 
Total Direct Recoveries ---------+- (6,673 
Total Indireet Recoveries - - ----+-- - 8,808 
Total Direct and Indirect Reeoveries Used - 12 "410 
Total Direct Recoveries from Bandings - - - 3,071 
During the Shooting Season in the States 
(these used for supplemental data only) 
These records inelude the following from 
bandings in Canada. 
Total Shooting Recoveries - -----+-=+ = 1,405 
Total Direct Recoveries - - -------- 994 
Total Indirect Recoveries = - - - - = - - — 411 
A breakdown of other methods of recovery during the fall 
(not used in the report) is as follows: 
Direct Indirect 
Found dead 19 89 
Found injured 1 16 
No information 13 val 
Steel traps 67 129 
Duck traps 17 91 
Killed by animal 5 15 
Band found 2 13 
Other 2 20 
126 Ald 
Sex and Age Determination 
Unfortunately early records on age and sex data are not as 
accurate as the data from certain bandings of the last few years. Had 
it been possible to analyze the records used for this report for diff- 
erential movements, the value of the report would have been enhanced 
considerably.
