Madison, Wisconsin: Wisconsin Department of Natural Resources
Summary
The objective of this investigation from 1968-1971 was to identify specific causes of hen pheasant mortality and to assess their relative importance on a seasonal and annual basis. Previous research in Wisconsin has provided a comprehensive evaluation of seasonal and annual mortality rates but only a glimpse of the importance of the individual mortality factors. Radio telemetry allowed the observer to maintain daily contact with individual birds and to get to the scene of death with a minimum of delay.
