Impacts of Precipitation on Northern Bobwhite Production in South Texas

Despite a long history of research on northern bobwhites (Colinus virginianus; hereafter, bobwhites), there has not been a comprehensive assessment of how bobwhite productivity varies across a landscape in relation to environmental factors such as weather. Due to concerns of global climate change and range-wide decline of the bobwhite, further understanding the relationship between weather and bobwhite population dynamics is needed. The objectives of this study were to determine 1) how do among-year bobwhite masses, age ratios, and sex ratios change at the landscape scale, 2) can fall...

Supplemental Feed and Northern Bobwhites: Considerations and Costs

Northern bobwhite (Colinus virginianus) populations are continuing a 30-year downward population trend throughout their range. Managers use supplemental corn (Zea mays) and milo (Sorghum spp.), trying to reverse the decline of bobwhite populations; however, results are conflicting among the published literature. Supplemental feed can influence bobwhite survival, reproduction, and movements, but only in situations where nutrients are truly lacking. Vitamin A, phosphorus (P), calcium (Ca), carbohydrates, and protein can be important nutrients for captive bobwhite egg production; however,...
