Influence Of Northern Bobwhite Nest Site Selection On Nest Survival In An Agricultural Landscape, Andy D. Richardson, Christopher E. Moorman, Craig Harper, Mark D. Jones, Benjy M. Strope
National Quail Symposium Proceedings
Working farms provide excellent potential for conserving northern bobwhite (Colinus virginianus) habitat in agricultural landscapes. Managing for areas of early successional vegetation can increase bobwhite abundance with little reduction in crop production on working farms, but the mechanisms behind the increase is not well known. Our objective was to determine nest site characteristics that may predict nest initiation and survival on agricultural lands to inform future management activities. We radio-collared 241 wild bobwhite on 1 farm with and 2 farms without bobwhite habitat management in southeastern North Carolina. Study sites consisted of a 1,740-ha farm with 9% of …
Response Of Grassland Birds To Agricultural Intensity At Different Spatial Scales In Texas, Anna Matthews, M. Clay Green, James Giocomo
Response Of Grassland Birds To Agricultural Intensity At Different Spatial Scales In Texas, Anna Matthews, M. Clay Green, James Giocomo
National Quail Symposium Proceedings
The decline in grassland birds is often associated with habitat loss due to intensity of conversion to agricultural lands and the alterations of natural disturbances. We sought to identify agricultural effects at differing scales that correlate to Texas grassland bird abundance, especially northern bobwhite (Colinus virginianus). Ninety-five roadside routes were surveyed in 20 Texas counties ranging from the Oklahoma border to the coastal plains. We conducted point counts in May and June from 2013 to 2016. To estimate the coarse effects of agriculture on bird abundance at a county level, we used number of cattle and area of …

Northern Bobwhite Demographic And Population Response Following An Intensive Habitat Modification To An Agricultural Landscape, Theron M. Terhune, D. Clay Sisson, Steven Mitchell, H. Lee Stribling
Northern Bobwhite Demographic And Population Response Following An Intensive Habitat Modification To An Agricultural Landscape, Theron M. Terhune, D. Clay Sisson, Steven Mitchell, H. Lee Stribling
National Quail Symposium Proceedings
Northern Bobwhite (Colinus virginianus) populations have been declining throughout most of their endemic range due to numerous factors (e.g., increased urbanization, predators); however, changing land-use practices have proved most detrimental to bobwhites. In parts of the southeastern USA, small-scale farming has been replaced by large-scale center-pivot irrigated fields and this has exacerbated habitat loss. Despite these trends, bobwhite populations in the Southeast have remained stable or increased on many areas employing intensive habitat management regimes, substantiating the importance of appropriate habitat management for long-term bobwhite persistence. In effort to reverse one such decline, we intensively modified a center-pivot, agriculture dominated …
Habitat Use And Survival Of Gray Partridge Pairs In Bavaria, Germany, Wolfgang Kaiser, Ilse Storch, John P. Carroll
Habitat Use And Survival Of Gray Partridge Pairs In Bavaria, Germany, Wolfgang Kaiser, Ilse Storch, John P. Carroll
National Quail Symposium Proceedings
Gray partridge (Perdix perdix) habitat studies have been undertaken in a number of countries but have generally focused on winter and brood rearing. We monitored survival of grey partridge pairs relative to habitat during the breeding season. Our study area was located near Feuchtwangen in north-west Bavaria, Germany. During 1991 to 1994, we used compositional analysis to assess habitat with survival and year as covariates for 38 radio-tagged partridge pairs. Comparing study area habitat to habitats within pair home ranges, we found overall habitat use was non-random with no year effect but a significant effect of survival status. Stubble habitat …
Characteristics Of Four Agricultural Crops Established As Northern Bobwhite Brood Habitat, Denise A. Maidens, John P. Carroll
Characteristics Of Four Agricultural Crops Established As Northern Bobwhite Brood Habitat, Denise A. Maidens, John P. Carroll
National Quail Symposium Proceedings
Small plots of agricultural crops are often planted in the Southeast for northern bobwhite (Colinus virginianus) management. Often these are viewed as primarily winter habitat, and assumed to provide summer habitat. We evaluated the macroinvertebrate and vegetative structure of millet, sorghum, wheat, and soybean plots on a cotton farm to assess their value as bobwhite brood habitat. During June and July 1999 and June, July, and August 2000, we studied 5 blocks, each planted with all 4 agricultural crops. We measured invertebrate abundance along a 15-meter transect in each plot using vacuum sampling and height/density of vegetation. Visual obstruction readings …

Arizona Quail: Species In Jeopardy?, Ron Engel-Wilson, William P. Kuvlesky Jr.
National Quail Symposium Proceedings
We begin the 21st century with the Midwestern northern bobwhite (Colinus virginianus) range reduced to a small portion of its historic distribution. This precipitous decline occurred largely during the last quarter of the 20th century, coincident with widespread intensive agricultural land use, unchecked natural plant succession, and frequent severe weather. Various bobwhite enthusiasts of the 1960s–1980s era including Klimstra, Dumke and Stanford had evaluated agricultural land use trends and predicted the near demise of bobwhites that we now lament. Alarmed upland bird hunters have repeatedly spurred policy makers and administrators into action. However, because bobwhites still are only an incidental …
Correlates Of Northern Bobwhite Distribution And Abundance With Land-Use Characteristics In Kansas, Stephen J. Brady, Curtis H. Flather, Kevin E. Church, Eric W. Schenck
Correlates Of Northern Bobwhite Distribution And Abundance With Land-Use Characteristics In Kansas, Stephen J. Brady, Curtis H. Flather, Kevin E. Church, Eric W. Schenck
National Quail Symposium Proceedings
County-level agricultural statistics were correlated with Rural Mail Carrier Survey reports and Breeding Bird Survey data for northern bobwhite (Colinus virginianus) in Kansas. Results indicate statewide analysis is feasible when temporally congruent data exist for both agricultural land-use characteristics and bobwhite distribution and abundance. Interpretations of these results can be useful in state or regional analysis and in the development of habitat management strategies for bobwhite. The Multiple Response Permutation Procedure identified 16 land-use variables, 3 soil variables, and 1 spatial variable that were significantly different in counties where bobwhite were present from counties where they were absent. Sixteen land-use …
Evaluation Of Foldable Tractor Roll-Over Protective Structures (Rops) Clearance, Luke Martin
Evaluation Of Foldable Tractor Roll-Over Protective Structures (Rops) Clearance, Luke Martin
Pursuit - The Journal of Undergraduate Research at The University of Tennessee
Tractor rollovers are a leading cause of death in the agricultural industry. While rollovers continue to happen, Roll-Over Protective Structures (ROPS) have shown great ability to prevent or reduce the casualties and injuries associated with rollover events. One authority on the subject even goes so far as to claim that “that fatality rates due to tractor overturns could be reduced by a minimum of 71% if all tractors in the U.S. were equipped with ROPS,” (NIOSH, 2009). The potential of this promising statistic has been devalued slightly due to the misapplication of foldable ROPS by leaving the ROPS in the …
