Temporal Patterns in Cause-specific Mortality of Northern Bobwhite in Northern Missouri

Wildlife Outstanding Technical Paper

Northern bobwhite populations have been declining throughout most of their range. Population declines imply that mortality consistently exceeds production and therefore a thorough understanding of the causes and temporal distribution of mortality is important. We present Heisey-Fuller estimates of monthly survival and cause-specific mortality rates of 1,001 radio-marked bobwhite on private lands in northern Missouri during 1989-1992. Monthly survival rate was lowest during the hunting season (November-January)(jc = 0.639), intermediate during the breeding season (May-September) (x = 0.815...
