Experiences In Northern Bobwhite Propagation And Translocation In Ohio, 1978-2012, Mark J. Wiley, Nathan J. Stricker
Experiences In Northern Bobwhite Propagation And Translocation In Ohio, 1978-2012, Mark J. Wiley, Nathan J. Stricker
National Quail Symposium Proceedings
Ohio once boasted a population of 7 million northern bobwhites (Colinus virginianus). Catastrophic blizzards during 1976–1977 and 1977–1978 brought winter quail mortalities of 85% and 80%, respectively. Ohio’s bobwhite population was 430,000 in 1978, a 90% reduction from 1976. Remnant quail populations were small, isolated, and incapable of rapid recovery. The Ohio Department of Natural Resources (ODNR) initiated a statewide stocking effort to expedite population growth. The ODNR chose to propagate wild quail in captivity and release first-generation progeny (F1). Throughout 1980–1986, the ODNR released 65,000 F1 quail statewide. The ODNR monitored population response with North American Breeding …
Temporal And Spatial Assessment Of Usable Space And Cover Type Interspersion For Northern Bobwhites On Private Farmlands In Southwestern Ohio, Robert J. Gates, Mark J. Wiley, Adam K. Janke, Marjorie R. Liberati
Temporal And Spatial Assessment Of Usable Space And Cover Type Interspersion For Northern Bobwhites On Private Farmlands In Southwestern Ohio, Robert J. Gates, Mark J. Wiley, Adam K. Janke, Marjorie R. Liberati
National Quail Symposium Proceedings
Contemporary landscape change driven by socio-economic forces and advances in agricultural technology do not favor northern bobwhites (Colinus virginianus) in the Midwestern United States. The challenge of bobwhite conservation is to provide sufficient quantities of habitat with optimal configurations in proportions that satisfy needs throughout the year on private-owned working lands. We radio-tracked 58 coveys and 98 individual birds throughout the year in 2009-10 and 2010-11 on privately owned farmland in southwestern Ohio. We investigated temporal changes in usable space from use-availability data. Estimated proportions of usable space based on analyses of habitat selection across four study sites …
Efficacy Of Targeted Mist-Netting To Capture Northern Bobwhites During The Non-Breeding Season In Ohio, Mark J. Wiley, Adam K. Janke, Robert J. Gates
Efficacy Of Targeted Mist-Netting To Capture Northern Bobwhites During The Non-Breeding Season In Ohio, Mark J. Wiley, Adam K. Janke, Robert J. Gates
National Quail Symposium Proceedings
Baited funnel traps and nightlighting are well established northern bobwhite (Colinus virginianus) capture techniques, but their use is not always appropriate, particularly on private land where cooperating landowners may place constraints on research activities. Alternative capture techniques may be more effective under conditions considered to be unfavorable for established techniques (e.g., periods with abundant natural food). Targeted mist-netting, where mist nets are erected near the known location of specific individuals, has been used to capture gallinaceous species and may be an effective alternative to established bobwhite capture techniques. We evaluated the effectiveness of using targeted mist-netting to capture bobwhites during …
Spring Dispersal Of Northern Bobwhites In Southwestern Ohio, Marjorie R. Liberati, Robert J. Gates
Spring Dispersal Of Northern Bobwhites In Southwestern Ohio, Marjorie R. Liberati, Robert J. Gates
National Quail Symposium Proceedings
Northern bobwhites (Colinus virginianus) historically occurred throughout Ohio but their core range has contracted to 18 southwestern counties. The Ohio Division of Wildlife has used trapping and transplanting to reintroduce wild bobwhites to unoccupied habitats within the species’ historic range. Bobwhite dispersal information is necessary to understand population dynamics and the species’ capacity to recolonize unoccupied habitats. Bobwhites were captured and radiomarked on 4 private-land study sites in southwestern Ohio. Radio-marked bobwhites (n 1⁄4 66) were tracked by homing or triangulation during spring 2010 and 2011 to ascertain dispersal distances between winter and breeding ranges. The spring dispersal period was …
Temporal Variability In Survival Of Non-Breeding Northern Bobwhites In Ohio, Adam K. Janke, Robert J. Gates
Temporal Variability In Survival Of Non-Breeding Northern Bobwhites In Ohio, Adam K. Janke, Robert J. Gates
National Quail Symposium Proceedings
Non-breeding season survival is an important determinant of population growth rates of northern bobwhites (Colinus virginianus) and is primarily influenced by hunter harvest, predation, and weather. The collective influence of these factors varies within and among years and across the bobwhite range. Understanding factors that influence variation in survival is important to inform regionally-specific management strategies for declining bobwhite populations. We radiomarked 311 bobwhites from 73 coveys to investigate temporal variation in non-breeding season (Oct-Mar) survival of a declining bobwhite population on private land in southwestern Ohio during 2008–2011. We used the data bootstrapping feature in Program MARK to adjust …
Demographic Analysis Of A Declining Northern Bobwhite Population In Southwestern Ohio, Robert J. Gates, Adam K. Janke, Marjorie R. Liberati, Mark J. Wiley
Demographic Analysis Of A Declining Northern Bobwhite Population In Southwestern Ohio, Robert J. Gates, Adam K. Janke, Marjorie R. Liberati, Mark J. Wiley
National Quail Symposium Proceedings
Northern bobwhite (Colinus virginianus) populations continue to decline throughout much of their range, especially in the Midwestern United States. Land use and habitat changes are understood to be the primary cause of decline, and it is unclear how vital rates affect growth of regional populations. We estimated relative abundance and population vital rates of bobwhites on 8 private land sites in southwestern Ohio during 2008–2011. Life stage simulation analyses were used to model the influence of 9 demographic parameters on population growth rates (k). All but one vital rate, chick survival, were modeled with empirical data randomly selected from normal …

In the fall of 1859, John Brown launched a raid on the federal arsenal at Harpers Ferry, Virginia, and in so doing arguably fired the first salvo of the Civil War. That his raid occurred in the border area between North and South should come as no surprise because it was in that area where Americans were the most divided. Citizens across the border state region–that area that comprised the lower North and upper South–soon found themselves caught between two hostile sections. Based on an analysis of letters, journals, newspapers, and public documents, this dissertation is a study of one …
