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
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 …
Phylogeography Of Scaled Quail, Damon L. Williford, Randall W. Deyoung, Leonard A. Brennan, Fidel Hernandez, Rodney L. Honeycutt
Phylogeography Of Scaled Quail, Damon L. Williford, Randall W. Deyoung, Leonard A. Brennan, Fidel Hernandez, Rodney L. Honeycutt
National Quail Symposium Proceedings
Scaled quail (Callipepla squamata) are distributed over much of the Chihuahuan Desert in the United States and south into central Mexico. Four subspecies have been described based on slight variations in coloration and body size, but the distinctiveness of the subspecies is unknown. We conducted a range-wide phylogeographic analysis of scaled quail based on the mitochondrial control region (D-loop). Our objectives were to: (1) ascertain the overall genetic diversity, (2) examine the phylogeographic structure of the scaled quail, and (3) examine the genetic distinctiveness of its 4 subspecies. We obtained D-loop sequences from 190 hunter-harvested wings and 38 museum specimens. …
The Forgotten Quail Decline: The Plight Of Scaled Quail In Texas, Fidel Hernandez, Chad J. Parent, Ian C. Trewella, Eric D. Grahmann
The Forgotten Quail Decline: The Plight Of Scaled Quail In Texas, Fidel Hernandez, Chad J. Parent, Ian C. Trewella, Eric D. Grahmann
National Quail Symposium Proceedings
Several quail species are experiencing range-wide declines in the United States. The northern bobwhite (Colinus virginianus) has garnered the most attention, both from a research and conservation perspective. The bobwhite decline in Texas, has resulted in considerable time and effort being devoted to research and management on the species due to its status as a highly popular and economically important game bird. This attention has been beneficial to bobwhite conservation and management but, an unfortunate consequence of this focus has been neglect of the scaled quail (Callipepla squamata) that has been declining at even a more alarming rate. Scaled quail, …
Scaled Quail Reproduction In The Trans-Pecos Region Of Texas, Robert J. Buntyn, Eddie K. Lyons, Dale Rollins, Kenneth A. Cearley
Scaled Quail Reproduction In The Trans-Pecos Region Of Texas, Robert J. Buntyn, Eddie K. Lyons, Dale Rollins, Kenneth A. Cearley
National Quail Symposium Proceedings
Scaled quail (Callipepla squamata) populations have declined markedly throughout their range. We monitored hatch rates and nest placement of radio-marked female scaled quail (n 1⁄4 210) in Pecos County, Texas relative to the availability and location of ‘spreader dams’ (i.e., shallow water catchments) through the nesting seasons of 1999 and 2000. Hatch rates were high both years (i.e., 67 and 84% for 1999 and 2000, respectively). The predominant nesting microhabitat was tobosa (Pleuraphis mutica), which accounted for 85% of the nests located. We failed to document any direct impacts of spreader dams on nesting ecology of scaled quail.
What’S A Quail Worth? A Longitudinal Assessment Of Quail Hunter Demographics, Attitudes, And Spending Habits In Texas, Jason L. Johnson, Dale Rollins, Kelly S. Reyna
What’S A Quail Worth? A Longitudinal Assessment Of Quail Hunter Demographics, Attitudes, And Spending Habits In Texas, Jason L. Johnson, Dale Rollins, Kelly S. Reyna
National Quail Symposium Proceedings
Funds generated and spent on the pursuit of quail (Colinus virginianus, Callipepla squamata) hunting in Texas are sizable. We surveyed a population of quail hunters in Texas in 2000 and 2011 to assess hunter demographics and spending habits. The population of hunters for the 2000 survey consisted of members of Quail Unlimited who lived in Texas while the 2011 population consisted of the former group’s successor in Texas—Quail Coalition. The initial (2000) survey was a mail questionnaire while the 2011 survey instrument was delivered electronically. We achieved response rates of 47% in 2000 but only 9% in 2011. The number …

Quail Response To Two Large-Scale Wildfires In The Texas Panhandle, Kenneth A. Cearley, Dale Rollins, Brandon Wilson
National Quail Symposium Proceedings
Rangeland wildfires burned 275,805 ha in 2 large blocks in the Texas Panhandle in March 2006. We assessed the impact on northern bobwhite (Colinus virginianus) and scaled quail (Callipepla squamata) populations through use of spring call-counts at 6 study sites during summer 2006–2008. Call-counts were higher in 2006 on non-burned (control) sites combined than on burned sites combined. Two years post-burn call-counts were higher on 3 of the burned sites and on 3 of the control sites. Between year comparisons revealed a difference only in the 2006/2007 pairing with 2006 having lower counts on burned than on control sites. Vegetation …

Survival Of Female Scaled Quail During The Breeding Season At Three Sites In The Chihuahuan Desert, Dale Rollins, Ben D. Taylor, Troy D. Sparks, Robert J. Buntyn, Scott E. Lerich, Louis A. Harveson, Tom E. Wadell, Cody B. Scott
National Quail Symposium Proceedings
Scaled quail (Callipepla squamata) populations declined markedly across much of their range from 1988-2004, however little research has been conducted to investigate possible causes for the decline. As part of a larger study on scaled quail ecology and management, and in an attempt to determine whether breeding season survival could be implicated in this decline, we monitored survival of radiotagged female scaled quail during the breeding season at sites in Brewster and Pecos counties, Texas, and Sierra County, New Mexico, USA during 1999-2003. Survival rates were calculated using Kaplan Meier analysis for birds living >7 days post capture. Interval survival …
Species Visitation At Quail Feeders And Guzzlers In Southern New Mexico, Dale Rollins, Ben D. Taylor, Troy D. Sparks, Tom E. Wadell, George Richards
Species Visitation At Quail Feeders And Guzzlers In Southern New Mexico, Dale Rollins, Ben D. Taylor, Troy D. Sparks, Tom E. Wadell, George Richards
National Quail Symposium Proceedings
Providing supplemental feed and water are sometimes used to manage scaled quail (Callipepla squamata) in the Chihuahuan Desert even though their biological and economical efficacies are questionable. Seasonal visitation rates of scaled quail and various nontarget species are important parameters affecting the efficacy of feeding and watering practices. However, empirical data on visitation by scaled quail at feeders and guzzlers are lacking. We used video surveillance to assess species visitation at free-choice quail feeders and guzzlers in south-central New Mexico during 2002. Scaled quail accounted for 19.4 and 21.5% of visitations at feeders and guzzlers, respectively. Mourning doves (Zenaida macroura), …

A Comparison Of Two Quail Abundance Indices And Their Relationship To Quail Harvest In Texas, Stephen J. Demaso, Markus J. Peterson, Jon R. Purvis, Nova J. Silvy, Jerry L. Cooke
National Quail Symposium Proceedings
Surveys are used to monitor status and trends of animal populations. However, different surveys may give conflicting results for the same species and population being surveyed. Therefore, we compared results of the North American Breeding Bird Survey (BBS) and Texas Parks and Wildlife (TPW) roadside counts for scaled quail (Callipepla squamata) and northern bobwhite (Colinus virginianus) in Texas. Surveys were compared on both an ecoregion and statewide basis. The BBS and TPW surveys gave similar trends for bobwhites and scaled quail for 5 of 8, and 3 of 5 ecoregions, respectively. Survey trends differed at the statewide scale for both …
Landscape-Scale Land-Cover Change And Long-Term Abundance Of Scaled Quail And Northern Bobwhite In Texas, Andrew S. Bridges, Markus J. Peterson, Nova J. Silvy, Fred E. Smeins, X. Ben Wu
Landscape-Scale Land-Cover Change And Long-Term Abundance Of Scaled Quail And Northern Bobwhite In Texas, Andrew S. Bridges, Markus J. Peterson, Nova J. Silvy, Fred E. Smeins, X. Ben Wu
National Quail Symposium Proceedings
Between 1978 and 1998, scaled quail (Callipepla squamata) abundance in the Rolling Plains ecological region declined (r1 = -0.85, P < 0.001), while no trend (P = 0.74) was exhibited in the South Texas Plains. Northern bobwhites (Colinus virginianus) exhibited no trend (P > 0.10) in either ecological region. Changes in land-cover between 1976 and 1998 indicated a loss of Savannah and Shrubland and an increase in Parkland cover types in the Rolling Plains. In the South Texas Plains, Woodland and Brush/Shrubland decreased between 1976 and 1998, whereas Brush/Shrub Parkland and Parkland increased. We examined land-cover change as a possible component in the scaled quail decline in the Rolling Plains. Loss of the Shrubland cover type may explain the decline of scaled quail in …
Sustaining The 'Quail Wave' In The Southern Great Plains, Dale Rollins
Sustaining The 'Quail Wave' In The Southern Great Plains, Dale Rollins
National Quail Symposium Proceedings
The southern Great Plains (i.e., Texas and Oklahoma) historically affords some of the best, and currently most stable, northern bobwhite (Colinus virginianus) populations anywhere. However, bobwhite populations have declined in recent years over much of this area, especially east of the 98th meridian. Two subsets of the southern plains, the Rolling Plains (parts of northwestern Texas, western Oklahoma, and western Kansas) and the Rio Grande Plains (south Texas) offer the most expansive, contemporary northern bobwhite habitat throughout its range. Bobwhite habitat in the southern plains is affected primarily by rainfall and rangeland management for livestock. Range management practices (brush control, …
