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
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. …
Survival And Nesting Ecology Of Scaled Quail In The Trans-Pecos, Texas, Carlos E. Gonzalez Gonzalez, Louis A. Harveson, Ryan S. Luna
Survival And Nesting Ecology Of Scaled Quail In The Trans-Pecos, Texas, Carlos E. Gonzalez Gonzalez, Louis A. Harveson, Ryan S. Luna
National Quail Symposium Proceedings
Scaled quail (Callipepla squamata) are one of the most ecologically and economically important wildlife species in the Trans-Pecos, because they are the primary upland game bird in the Chihuahuan Desert. Using radiotelemetry, we evaluated survival (Kaplan–Meier) and nesting success of quail on 3 study sites in the Trans-Pecos, Texas: one (Santiago Mountain Ranch, central Brewster Co.) was supplemented with milo (Sorghum bicolor) year-round, the second (Lado Ranch, south Culberson Co.) never used supplements, and the third (Apache Ranch, central Culberson Co.) was supplemented with quail blocks. We trapped and radiocollared 164 female quail collectively across all …
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
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
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 …
Evaluation Of Population Indices And Estimators For Scaled Quail In The Rolling Plains Of Texas, Bradley Kubečka, John T. Edwards, Fidel Hernández, Dale Rollins
Evaluation Of Population Indices And Estimators For Scaled Quail In The Rolling Plains Of Texas, Bradley Kubečka, John T. Edwards, Fidel Hernández, Dale Rollins
National Quail Symposium Proceedings
Accurate and precise population indices and estimators are important to gain reliable knowledge and make appropriate management decisions. Indices and estimators for scaled quail (Callipepla squamata), however, have not been evaluated thoroughly. Our objectives are to compare relationships among 8 years of roadside counts, spring call counts, and mark-recapture data obtained from the Rolling Plains Quail Research Ranch in Fisher County, TX, USA. Furthermore, we assess the efficacy of distance-based helicopter surveys as a method for scaled quail density estimates as compared to mark-recapture estimates for 2016–2017.
Population Response Of Three Quail Species To Habitat Restoration In South Texas, Eric D. Grahmann, Fidel Hernández, Leonard A. Brennan, Timothy E. Fulbright, Carter Crouch, Michael W. Hehman, David Heft, Robert Perez, Fred C. Bryant
Population Response Of Three Quail Species To Habitat Restoration In South Texas, Eric D. Grahmann, Fidel Hernández, Leonard A. Brennan, Timothy E. Fulbright, Carter Crouch, Michael W. Hehman, David Heft, Robert Perez, Fred C. Bryant
National Quail Symposium Proceedings
Maintaining and increasing usable space is paramount for maintaining and increasing wild quail. Aside from weather and other factors that can temporarily reduce densities, range-wide, no factor has as much influence on quail populations as the amount of habitat present across the landscape. In the field of quail management, ‘‘bad news’’ is the norm, as many articles begin by explaining how a select species has declined. Here we provide good news and use 4 empirical examples of population increases for 3 quail species following creation of usable space and restoration of patch connectivity. From 2008–2014, a suite of independent projects …
