Book Description
A mail questionnaire survey of waterfowl hunters is conducted each year in the United States to provide information on waterfowl kill and hunter activity. We carried out a study using data from the 1971-73 and 1972-73 hunting seasons to determine the effectiveness of the present U.S. sampling and estimation techniques, and a number of modifications in both sampling and analysis is recommended.
