Efficacy Of A Soft Release Strategy For Translocating Scaled Quail In The Rolling Plains Of Texas, Rebekah E. Ruzicka, Kara B. Campbell, Michelle C. Downey, Dale Rollins, Bradley Kubečka, Matthew Poole, Donald C. Ruthven

National Quail Symposium Proceedings

Scaled Quail (Callipepla squamata) populations have become locally extinct and spatially fragmented in the Rolling Plains ecoregion of Texas. Translocating Scaled Quail from core to declining populations could augment populations or re-establishing extinct populations. Although translocations of scaled quail have been attempted in Texas, none have been documented and none have attempted to identify best practices. Release strategy (i.e., hard or soft release) is a factor that can influence the success of a translocation. Our objective was to compare daily apparent survival of scaled quail translocated to the Rolling Plains between 2 release treatment groups: hard- and soft-release. …


Effects Of Source Population And Release Strategy On Survival And Dispersal Of Translocated Scaled Quail In The Rolling Plains Of Texas—A Preliminary Report, Rebekah E. Ruzicka, Dale Rollins Nov 2017

Effects Of Source Population And Release Strategy On Survival And Dispersal Of Translocated Scaled Quail In The Rolling Plains Of Texas—A Preliminary Report, Rebekah E. Ruzicka, Dale Rollins

National Quail Symposium Proceedings

Scaled quail (Callipepla squamata) have declined 3.5% annually in Texas from 1966-2013, but declines have not been uniform across the state. The Rolling Plains Ecoregion has experienced a 6.8% decrease during this period, while the western Edwards Plateau has remained stable. Habitat loss that has contributed to scaled quail decline also inhibits recolonization. Translocation has become an increasingly popular tool to reestablish populations for recreational or conservational purposes. Overall success rate of translocations is low and has prompted research into factors that contribute to the establishment of a self-sustaining population. Source population and release strategy are two translocation …


Application Of Metapopulation Theory To Northern Bobwhite Conservation, Joseph P. Sands, Stephen J. Demaso, Leonard A. Brennan, Damon L. Williford, Randall W. Deyoung, Erin M. Wehland, Fidel Hernandez, Katherine S. Miller Jul 2017

Application Of Metapopulation Theory To Northern Bobwhite Conservation, Joseph P. Sands, Stephen J. Demaso, Leonard A. Brennan, Damon L. Williford, Randall W. Deyoung, Erin M. Wehland, Fidel Hernandez, Katherine S. Miller

National Quail Symposium Proceedings

Northern bobwhite (Colinus virginianus) populations have declined throughout the majority of the species’ range, and have experienced the largest declines in fragmented habitats, suggesting landscape scale processes may be responsible for this decline. We used the results from a stochastic population dynamics model of South Texas bobwhites as conceptual justification for use of metapopulation theory in bobwhite management. Annual quasi-extinction probabilities for isolated bobwhite populations were 0.003 (95% CI: 0.001 0.006), 0.105 (95% CI: 0.083 0.126), and 0.773 (95% CI: 0.750 0.796) for simulated populations harvested at 20, 30, and 40% annually. The probability of regional persistence at 30% harvest …


Genetic Structure And Diversity In South Texas Bobwhites: Implications For Conservation, Randall W. Deyoung, Erin M. Wehland, Damon L. Williford, Angeline Zamorano, Joseph P. Sands, Leonard A. Brennan, Fidel Hernandez, Stephen J. Demaso, Robert M. Perez Jul 2017

Genetic Structure And Diversity In South Texas Bobwhites: Implications For Conservation, Randall W. Deyoung, Erin M. Wehland, Damon L. Williford, Angeline Zamorano, Joseph P. Sands, Leonard A. Brennan, Fidel Hernandez, Stephen J. Demaso, Robert M. Perez

National Quail Symposium Proceedings

The northern bobwhite (Colinus virginianus) has experienced range-wide declines in population size and reductions in geographic range during the last century. Declines in northern bobwhite population size and geographic distribution continue to occur despite vigorous conservation and research efforts directed at sustaining and enhancing populations. Viable populations of northern bobwhite have persisted only in areas with large expanses of relatively contiguous habitat, such as southern Texas, parts of Oklahoma, Kansas, and areas in southern Georgia and northern Florida. The decline of northern bobwhite populations is often associated with changes in land- use practices, including proliferation of intensive agriculture and fire …


Spring Dispersal Of Northern Bobwhites In Southwestern Ohio, Marjorie R. Liberati, Robert J. Gates Jul 2017

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 …


Propagation Effectiveness Of The Surrogator For Northern Bobwhites In Southern Texas, John C. Kinsey, Michael F. Small, Thomas R. Simpson, Robert M. Perez, John T. Baccus Jul 2017

Propagation Effectiveness Of The Surrogator For Northern Bobwhites In Southern Texas, John C. Kinsey, Michael F. Small, Thomas R. Simpson, Robert M. Perez, John T. Baccus

National Quail Symposium Proceedings

Attempts to restore populations of northern bobwhites (Colinus virginianus) using pen-raised quail have been documented since the early 1900s. Low restoration success, based on low post-release survival rates and long distance dispersal from release sites, have proven the ineffectiveness of pen-raised quail in restoration of wild populations. The Surrogatort, a recent quail propagation tool using pen-raised quail, has been publicized as a method for increasing success rates in restoration of northern bobwhite populations by producing higher post-release survival and minimal dispersal. We tested the hypothesis that the Surrogatort is an effective means of supplementing populations of northern bobwhites in southern …


Effects Of Sex, Age, And Habitat On Northern Bobwhite Spring Dispersal Patterns, M. Patrick Cook, Richard G. Hamrick, John P. Carroll Jul 2017

Effects Of Sex, Age, And Habitat On Northern Bobwhite Spring Dispersal Patterns, M. Patrick Cook, Richard G. Hamrick, John P. Carroll

National Quail Symposium Proceedings

Information on northern bobwhite (Colinus virginianus) dispersal patterns is crucial for implementing effective management strategies. Researchers have examined bobwhite dispersal, but information on how habitat affects dispersal patterns is lacking. We examined the effects of habitat, sex, and age on bobwhite spring dispersal patterns in a southern Georgia agricultural landscape during 2002-2003. Of 101 birds used in our analyses, 29.7% (4.6 SE) dispersed an average of 1,835m (194 SE). We fit 9 logistic regression models to predict bobwhite dispersal probability. The selected best model (Akaike weight [ω] = 0.58) included age, proportions of closed-canopy pine within winter home ranges (CCPN), …


Breeding Season Movements And Dispersal Of Northern Bobwhites In Fragmented Habitats Of Virginia, Michael L. Fies, K. Marc Puckett, Bonnie Larson-Brogdon Jul 2017

Breeding Season Movements And Dispersal Of Northern Bobwhites In Fragmented Habitats Of Virginia, Michael L. Fies, K. Marc Puckett, Bonnie Larson-Brogdon

National Quail Symposium Proceedings

To better understand dispersal patterns of northern bobwhites (Colinus virginianus) in fragmented habitats, we measured breeding season movements of 198 radiomarked bobwhites in central and eastern Virginia during 1994–1996. Mean distance between arithmetic centers of winter (1 Feb–15 Apr) and early breeding season (16 Apr–30 Jun) activity areas was 1,194 +- 137 m. Distance between centers of winter and late breeding season (1 Jul–15 Sep) activity areas averaged 1,644 +- 209 m and was greater for juveniles than adults (P = 0.04). Maximum distances moved between winter and breeding season locations (early, late, and combined) was also greater for juveniles …
