摘要

A landscape-scale assessment of how bobwhite productivity varies in relation to weather does not exist for northern bobwhite (Colinus virginianus). We collected age and sex ratio and body mass data from hunter-harvested bobwhites in 16 counties of South Texas (n=72,797 bobwhites) during 20012009 hunting seasons. We evaluated annual bobwhite production (juvenile:adult age ratios) as a function of cumulative AprilAugust rainfall using National Oceanic and Atmospheric Administration (NOAA) weather station data from Falfurrias and Hebbronville, Texas. We observed minimal among-year change in percent males harvested (51.054.5% male) and mean mass (156160g) of bobwhites across South Texas. We found no relationship between percent male or body mass and weather. We documented a positive, linear relationship between cumulative AprilAugust rainfall and bobwhite age ratios (r2=0.94); we also documented a negative, linear relationship between summer (JunAug) mean maximum daily temperature and bobwhite age ratios (r2=0.38). Our results suggest that rainfall is a landscape-scale indicator of annual bobwhite production in South Texas and can thus be used to manage annual expectations of quail hunters prior to the hunting season
