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 Nov 2017

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 Nov 2017

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 Nov 2017

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 Nov 2017

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 Nov 2017

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 Nov 2017

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 …
