Dear Waterfowl Hunter: 
Your response to the waterfowl mail questionnaire sent you 
last year is appreciated. The information you provided was of 
material assistance in measuring the size of the hunting kill and 
providing other important information. Since you have evidenced 
an interest in waterfowl management we would like your assistance 
and cooperation in a further study to be undertaken during the 
1959-60 waterfowl hunting season. This year we would like to 
have one wing from each duck that you shoot throughout the entire 
season. From these wings, we can determine the percentage of 
young birds among those bagged and thus obtain a measure of 
hatching success. This information is being collected as a 
cooperative study by the Bureau of Sport Fisheries and Wildlife 
and the Mississippi Flyway Council, of which your State is a member. 
Your help will provide information required for better management 
of our waterfowl resources. 
Please follow these instructions: 
1. Cut off wing (see back of enclosed envelope). 
2. To avoid confusion, please place the wing in envelope 
before removing wing from next bird. Use one envelope 
for each bird. We need only one wing from each bird. 
3. Fill in blanks on envelope. If the bird was banded, 
please send the band. We will return it if you wish. 
4, Mail as soon as possible (no postage required). Prompt 
‘mailing will reduce spoilage. 
5, Please continue to send wings as birds are taken. We 
must receive wings taken at all times during the hunting 
season in order to understand differences in migration 
among species and between young and old birds. Do not 
wait until end of season to send in wings.

6. If more envelopes are needed, send us a post card. 
Good Hunting! 
Sincerely yours,
