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.

Bald eagles (Haliaeetus leucocephalus) associate with wintering waterfowl concentrations throughout the United States, but little detailed information is available on eagle-waterfowl relations. This report concerns the ecology of bald eagles wintering in the vicinity of Swan Lake National Wildlife Referenc in north-central Missouri and, more specifically, examines the association of the eagles with waterfowl during the winters of 1975-76, 1976-77, and 1977-78
