Breeding Season Space Use And Habitat Selection Of Adult Female Scaled And Gambel's Quail In West Texas, Richard A. Temple, Louis Harveson, Ryan S. Luna
National Quail Symposium Proceedings
We used radiotelemetry to investigate breeding-season (1 Apr–1 Sep, 2012 and 2013) home ranges and habitat selection of adult female scaled (Callipepla squamata) and Gambel’s quail (C. gambelii) in the eastern Chihuahuan Desert, Texas. Mean breeding-season home range (95% fixed kernel) for scaled quail was 145.02 ± 23.56 ha (range = 22.03–538.24 ha) and 156.32 ± 13.04 ha (range = 66.15– 270.74 ha) for Gambel’s quail. Mean core-use area (50% fixed kernel) for scaled quail was 31.38 ± 4.80 ha (range = 4.03–111.36 ha) and 32.87 ± 2.61 ha (range = 12.19–52.36 ha) for Gambel’s quail. …
Using First Passage Time Analysis To Identify Foraging Patterns Of The Northern Bobwhite, Diana J. Mcgrath, Theron M. Terhune Ii, James A. Martin
Using First Passage Time Analysis To Identify Foraging Patterns Of The Northern Bobwhite, Diana J. Mcgrath, Theron M. Terhune Ii, James A. Martin
National Quail Symposium Proceedings
Patterns in movement data can reveal important information relating environmental variables to behavioral mechanisms. First passage time analysis (hereafter; FPT) can be used to quantify the spatial and temporal variation in movements by identifying areas of restricted search behavior based on measuring residence time in an area. It is applicable in studies of foraging ecology and habitat selection because it can empirically quantify behavioral decisions without any a priori assumptions of habitat availability. Furthermore, FPT analysis is simple to implement and interpret; however, the technique has yet to be applied to the northern bobwhite (Colinus virginianus, hereafter bobwhite) …

Winter Survival And Habitat Selection By Translocated Northern Bobwhite In The New Jersey Pine Barrens: Preliminary Results, Kaili R. Stevens, Philip M. Coppola, Christopher K. Williams, Theron M. Terhune Ii, John P. Parke, John Cecil
National Quail Symposium Proceedings
Northern bobwhite (Colinus virginianus) populations have been experiencing precipitous range-wide declines for more than 50 years; some of the steepest declines occurring in the Mid-Atlantic states. These declines are largely attributed to habitat deterioration from urban sprawl, change in forest management, and intensive farming. This ongoing study aims to evaluate the efficacy of translocating wild bobwhites into the New Jersey Pine Barrens as a means to restore their historic populations. Translocation has proven relatively successful in augmenting bobwhite populations in other regions as well as restoring populations of gallinaceous species. This portion of the study aims to investigate …

Summer Survival Of Translocated Northern Bobwhite In The New Jersey Pine Barrens: Preliminary Results, Philip M. Coppola, Kaili R. Stevens, Christopher K. Williams, Theron M. Terhune Ii, John P. Parke, John Cecil
National Quail Symposium Proceedings
Northern bobwhite (Colinus virginianus) have declined precipitously since the 1960s, largely due to habitat deterioration and changes in land use; some of the highest declines have been observed in the Mid-Atlantic States. In other regions, attempts to augment bobwhite populations have been relatively successful using translocation. As part of a long-term restocking program, focal areas for translocation in the mid-Atlantic region were identified by biologists at a National Bobwhite Conservation Initiative (NBCI) workshop. The objective of this project is to evaluate translocation to restore bobwhite populations in the New Jersey Pine Barrens, a focal area designated with a …
Habitat Space Used By Northern Bobwhites And Texas Tortoises On South Texas Rangelands, Ross O. Couvillon, Leonard A. Brennan, Fidel Hernández, Bart M. Ballard, Thomas V. Dailey
Habitat Space Used By Northern Bobwhites And Texas Tortoises On South Texas Rangelands, Ross O. Couvillon, Leonard A. Brennan, Fidel Hernández, Bart M. Ballard, Thomas V. Dailey
National Quail Symposium Proceedings
South Texas rangelands are increasingly managed for recreational hunting, particularly northern bobwhite (Colinus virgianus). Effects of habitat management for game species on non-game species are largely unknown. Large private ranches used for recreational hunting could also provide habitat for the threatened Texas tortoise (Gopherus berlandieri). We studied habitat use of Texas tortoises and northern bobwhites on a private ranch in South Texas that undergoes active habitat management. In 2015, tortoises (n = 12) and bobwhite hens (n = 42) were tracked during their active and breeding seasons, respectively, with radio-telemetry. Satellite images were analyzed …
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 …

Northern Bobwhite Survival, Nest Success, And Habitat Use In Kentucky During The Breeding Season, Andrew S. West, Patrick D. Keyser, John J. Morgan
National Quail Symposium Proceedings
Northern bobwhite (Colinus virginianus) populations have experienced protracted declines over much of their range. There has been an annual decrease of 2.61% since the 1960s in Kentucky, an area representative of the Mid-South where there is a lack of data on basic population parameters. Much of the decline is attributed to prevailing land-use practices and associated habitat loss. We monitored northern bobwhite on a 515-ha farm in Oldham County, Kentucky to assess survival rates, nest success rates, and habitat use in the Mid- South. The farm consisted of row crops, cool-season pastures and hay (primarily tall fescue), fallow native warm-season …
Habitat Selection By Northern Bobwhite Broods In Pine Savanna Ecosystems, William E. Palmer, D. Clay Sisson, Shane D. Wellendorf, Allan M. Bostick Iii, Theron M. Terhune, Tyson L. Crouch
Habitat Selection By Northern Bobwhite Broods In Pine Savanna Ecosystems, William E. Palmer, D. Clay Sisson, Shane D. Wellendorf, Allan M. Bostick Iii, Theron M. Terhune, Tyson L. Crouch
National Quail Symposium Proceedings
Habitat for northern bobwhite (Colinus virginianus) broods is a critical component of bobwhite management. Research within pine (Pinus spp.) savannas has provided contradictory results regarding the value of macro-habitats with studies demonstrating selection for annually-disked fallow fields and others showing avoidance of fields and selection for burned pine savannas. Field establishment (up to 30% of a property) is a published management recommendation for bobwhites in pine savannas but there are significant annual costs with fallow-field management; information on factors that influence habitat selection by broods can improve management recommendations and facilitate weighing costs/benefits. We examined 2nd and 3rd order habitat …
How To Re-Introduce Gray Partridges - Conclusions From A Releasing Project In Switzerland, Francis Buner
How To Re-Introduce Gray Partridges - Conclusions From A Releasing Project In Switzerland, Francis Buner
National Quail Symposium Proceedings
Once a widespread farmland bird in Switzerland, the Gray Partridge (Perdix perdix) has declined drastically since the 1960’s as a result of agricultural intensification and changes in predator abundance. In 1991 the wild population had dropped to ≈ 17 pairs only. We initiated a reintroduction experiment of Gray Partridge to investigate its feasibility for conservation of the species in Switzerland. Between 1998 and 2001 we released 145 partridges in the Swiss Klettgau, an intensively cultivated area from which the species had become extinct in 1993, but had since been ecologically enhanced with wild-flower strips and hedges up to 5.8% 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
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 …
