Effects Of Two Commercial Game Bird Feeds On Captive Northern Bobwhite Chick Growth Rates, Andrew N. Tri, Fidel Hernandez, David G. Hewitt, William P. Kuvlesky Jr. Jul 2017

Effects Of Two Commercial Game Bird Feeds On Captive Northern Bobwhite Chick Growth Rates, Andrew N. Tri, Fidel Hernandez, David G. Hewitt, William P. Kuvlesky Jr.

National Quail Symposium Proceedings

Supplemental feeding of northern bobwhites (Colinus virginianus) is a widespread management practice. Bobwhite chicks in the wild consume only arthropods for their first 30–60 days of life. Arthropods may become less abundant and managers have supplied bobwhites with supplemental feed during times of drought to mitigate the lack of arthropods. We compared growth rates of captive bobwhite chicks consuming a new, commercial 24% crude protein supplement to growth rates of bobwhites consuming a commercial 30% crude protein complete ration. There was no male/female bias related to chick growth. Chicks consuming the 24% protein diet grew slower and reached adult mass …

Fecundity Of Wild Northern Bobwhite Hens Under Hatchery Conditions, John T. Baccus, Kevin W. Dees, Michael F. Small, Thomas R. Simpson Jul 2017

Fecundity Of Wild Northern Bobwhite Hens Under Hatchery Conditions, John T. Baccus, Kevin W. Dees, Michael F. Small, Thomas R. Simpson

National Quail Symposium Proceedings

We describe egg production by 88 pairs of randomly selected, mature, wild-caught northern bobwhite (Colinus virginianus) hens housed under optimal conditions of food, water, climate, and a 17-hr photoperiod in a hatchery. We collected eggs daily using an 18-day period to differentiate between clutches. Hens continuously laid eggs until ceasing production. We evaluated number of eggs laid by each hen individually and hens collectively including total number, number/clutch, number/day, hatching success, and egg mass. Eighty-six hens produced 5,888 eggs. Number of eggs produced by individual hens ranged from 0 to 172 over ~ 200 days. Mean number of eggs laid/hen/day …

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 …

Survival And Reproduction Of Parent-Reared Northern Bobwhites, William E. Palmer, Randy D. Cass, Shane D. Wellendorf, Jerald F. Sholar, Theron M. Terhune, John P. Carroll Jul 2017

Survival And Reproduction Of Parent-Reared Northern Bobwhites, William E. Palmer, Randy D. Cass, Shane D. Wellendorf, Jerald F. Sholar, Theron M. Terhune, John P. Carroll

National Quail Symposium Proceedings

Captive-reared and released game birds typically have low reproductive success in the wild which limits their use for restoration of game bird populations. A fundamental problem with captive-rearing techniques is the absence of a mechanism for imprinting. We developed a parent-rearing technique that facilitates pre- and post-hatch imprinting using parent-reared wild strain northern bobwhite (Colinus virginianus) chicks in outdoor pens. Parent-reared chicks were marked with patagial wing tags and recaptured during October and the following March. We radiomarked juveniles captured in March to monitor survival and reproductive success in two separate studies, one in Georgia, and one in South Carolina, …

Nest-Site Characteristics Of Northern Bobwhites Translocated Into Weeping Lovegrass Crp, C. Wade Abbott, C. Brad Dabbert, Duane R. Lucia, Robert B. Mitchell, Alicia K. Andes Jul 2017

Nest-Site Characteristics Of Northern Bobwhites Translocated Into Weeping Lovegrass Crp, C. Wade Abbott, C. Brad Dabbert, Duane R. Lucia, Robert B. Mitchell, Alicia K. Andes

National Quail Symposium Proceedings

Habitat loss and fragmentation have been considered major causes for the decline of northern bobwhite (Colinus virginianus). There are . 400,000 ha of weeping lovegrass (Eragrostis curvula) Conservation Reserve Program (CRP) fields in the Southern High Plains of Texas some of which could be modified to provide usable habitat for northern bobwhites. Timely colonization of improved CRP habitat by northern bobwhite is unlikely without transplantation, because of distance from existing populations. We radio-marked and transplanted 94 northern bobwhite into weeping lovegrass CRP and monitored nest success. We recorded high nest success in 2002 (70%) and 2003 (71%) for northern bobwhite …

Distance-Based Habitat Associations Of Northern Bobwhites In A Fescue-Dominated Landscape In Kansas, Brian E. Flock, Philip S. Gipson, Roger D. Applegate, Warren B. Ballard

National Quail Symposium Proceedings

Northern bobwhites (Colinus virginianus) have a wide distribution across North America which influences its’ associations with habitats in a variety of landscapes. We used radio-marked bobwhites and Euclidean distance to characterize land cover associations of bobwhites at generalized level 1 and specific level 2 land cover classifications during the reproductive (15 Apr-14 Oct) and covey (15 Oct-14 Apr) periods in southeastern Kansas from 2003 to 2005. Habitat associations occurred during the reproductive (Wilkes’ k 1⁄4 0.04, F6,36 1⁄4 143.682, P , 0.001) and covey (Wilkes’ k 1⁄4 0.056, F6, 29 1⁄4 81.99, P , 0.001) periods.

Quail Response To Two Large-Scale Wildfires In The Texas Panhandle, Kenneth A. Cearley, Dale Rollins, Brandon Wilson Jul 2017

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 …

Impacts Of Invasive, Exotic Grasses On Quail Of Southwestern Rangelands: A Decade Of Progress?, William P. Kuvlesky Jr., Leonard A. Brennan, Timothy E. Fulbright, Fidel Hernandez, Steven J. Demaso, Joseph P. Sands, Robert M. Perez, Jason B. Hardin Jul 2017

Impacts Of Invasive, Exotic Grasses On Quail Of Southwestern Rangelands: A Decade Of Progress?, William P. Kuvlesky Jr., Leonard A. Brennan, Timothy E. Fulbright, Fidel Hernandez, Steven J. Demaso, Joseph P. Sands, Robert M. Perez, Jason B. Hardin

National Quail Symposium Proceedings

Exotic grass invasions are a serious concern for State and Federal agencies, non-government organizations, and private landowners engaged in quail conservation and management. Quail biologists recognized the potential negative impacts of exotic grass invasion on North American quail populations 2 decades ago. This issue was addressed in a review paper published in the Proceedings of the 5th National Quail Symposium in 2002. That paper reported the state of our knowledge on impacts of exotic grass invasions on 5 quail species inhabiting southwestern rangelands. Our objective is to update the progress of exotic grass-quail research on southwestern rangelands during the past …

On Some Founding Ideas Of Quailology And Their Propounders, Fred S. Guthery Jul 2017

On Some Founding Ideas Of Quailology And Their Propounders, Fred S. Guthery

National Quail Symposium Proceedings

Powerful ideas in quailology affect thinking over generations, even if the ideas are wrong. I discuss great ideas put forth by Aldo Leopold, Herbert Lee Stoddard, and Paul Lester Errington and comment on aspects of their personalities. Leopold, an extraordinarily good father, posited the Law of Dispersion (Interspersion), which became known as the Principle of Edge. The Law is a tautology that can be paraphrased ‘edge-obligate animals require edge.’ Leopold observed the ‘law’ held ‘within ordinary limits,’ which he did not define but which could mean ‘within compositionally simple landscapes.’ As a child, Stoddard, who dropped out of high school …

Additional Evidence Against Radio-Handicapping Of Northern Bobwhites, D. Clay Sisson, Theron M. Terhune, H. Lee Stribling Jul 2017

Additional Evidence Against Radio-Handicapping Of Northern Bobwhites, D. Clay Sisson, Theron M. Terhune, H. Lee Stribling

National Quail Symposium Proceedings

The validity of radio-telemetry to produce reliable information (e.g., survival estimates) has recently been challenged. Radio-telemetry is a widely used technique in studies of numerous species, therefore, concerns regarding potential bias in these estimates warrant further investigation. As such, and as part of a larger study, we investigated 3 aspects of potential radio-bias: 1) variation in survival distributions among treatment (newly radio-tagged) and control (previously radio-tagged) groups; 2) proportion of trapped animals censored during the traditional 7-day censor period; and 3) ramifications to cause-specific mortality through estimation of harvest rate. Kaplan-Meier survival, based on 30-day post trapping, was similar between …

Age Determination Of Pheasants (Phasianus Colchicus) Using Discriminant Analysis, Maureen I.A. Woodburn, John P. Carroll, Peter A. Robertson, Andrew N. Hoodless Jul 2017

Age Determination Of Pheasants (Phasianus Colchicus) Using Discriminant Analysis, Maureen I.A. Woodburn, John P. Carroll, Peter A. Robertson, Andrew N. Hoodless

National Quail Symposium Proceedings

Most gallinaceous birds can be identified as juveniles or adults using the outermost primaries (P9 and P10) which are retained until after the first breeding season and are often identifiable by colour and wear. The pheasant Phasianus colchicus, however, moults all ten primary feathers during its post-juvenile moult so alternative techniques are required. To date the method most widely used on live birds is measurement of the shaft diameter of the proximal primary feather, P1, which is replaced first before the bird is fully-grown. Using a known-age sample of 752 free-living pheasants, this study presents a discriminant function analysis using …

A Method For Determining Asymptotes Of Home-Range Area Curves, Aaron M. Haines, Fidel Hernandez, Scott E. Henke, Ralph L. Bingham Jul 2017

A Method For Determining Asymptotes Of Home-Range Area Curves, Aaron M. Haines, Fidel Hernandez, Scott E. Henke, Ralph L. Bingham

National Quail Symposium Proceedings

Home-range area curves are used to estimate the number of locations needed to accurately estimate home range size based on the asymptote of the curve. However, the current methodology used to identify asymptotes for home-range area curves is largely subjective and varies between studies. Our objective was to evaluate the use of exponential, Gompertz, logistic, and reciprocal function models as a means for identifying asymptotes of home-range area curves. We radio monitored northern bobwhite (Colinus virginianus) coveys during mid-September through November 2001-2002 in Jim Hogg County, Texas. We calculated home-range size of radiomarked coveys using the 95% fixed kernel with …

Survival And Causes Of Mortality For Northern Bobwhites In The Southeastern Usa, D. Clay Sisson, Theron M. Terhune, H. Lee Stribling, Jerald F. Sholar, Steven D. Mitchell

National Quail Symposium Proceedings

Long-term studies are imperative to increase our knowledge of northern bobwhite (Colinus virginianus; hereafter bobwhite) demographics. During 1992-2005, we determined survival and cause-specific mortality of bobwhites on 10 study areas in southern Georgia and eastern Alabama, USA.We radio-tagged 7,105 bobwhites and determined 49 annual (Oct-Sep) and 110 seasonal survival estimates to examine spatial and temporal variation in survival. Annual survival for all sites and years combined averaged 0.196 (SE = 0.011) and ranged from 0.08 to 0.40. Over-winter (Oct - Mar) seasonal survival estimates (n = 51) averaged 0.541 (SE = 0.019) and ranged between 0.25 and 0.82, while breeding …

An Evaluation Of Short-Term Mesocarnivore Control For Increasing Hatch Rate In Northern Bobwhites, Eddie K. Lyons, Jason Frost, Dale Rollins, Cody Scott Jul 2017

An Evaluation Of Short-Term Mesocarnivore Control For Increasing Hatch Rate In Northern Bobwhites, Eddie K. Lyons, Jason Frost, Dale Rollins, Cody Scott

National Quail Symposium Proceedings

We evaluated the efficacy of short-term trapping on scent-station visitation rates for some nest predators and survival of artificial nests with chicken eggs at 4 sites in west Texas from 1998-2001. Trapping of predators was conducted with cage traps for 30 days just prior to nest initiation (mid-May through mid-June) at a trap density of 1 trap/20 ha. Each site included a treatment (trapped) and control (non-trapped) area that comprised approximately 250 ha. Scent stations were employed before and after trapping to assess impacts of trapping on predator activity/abundance. Simulated nests (using 3 chicken eggs) were established 1-2 days after …

Over-Winter Survival Of Northern Bobwhite In Relation To Landscape Composition And Structure, R. Douglass Holt, Loren W. Burger Jr., Bruce D. Leopold, Dave Godwin Jul 2017

Over-Winter Survival Of Northern Bobwhite In Relation To Landscape Composition And Structure, R. Douglass Holt, Loren W. Burger Jr., Bruce D. Leopold, Dave Godwin

National Quail Symposium Proceedings

The conceptualization of security of bobwhite during winter has been predicated on the assumption that winter ranges differ in quality, based on habitat structure, composition, or interspersion. Although some studies have qualitatively related habitat composition to survival, no studies have quantitatively linked habitat or landscape characteristics to winter survival and the specific structural or compositional characteristics that influence quality are unknown. To quantify winter habitat quality, we modeled hazards as a function of habitat characteristics in relation to winter survival of radio-marked bobwhite (2000, n = 118 in 16 coveys; 2001, n = 49 in 7 coveys) in a managed …

A Review Of Crippling Loss For Northern Bobwhites, Aaron M. Haines, Fidel Hernandez, Scott E. Henke, Ralph L. Bingham Jul 2017

A Review Of Crippling Loss For Northern Bobwhites, Aaron M. Haines, Fidel Hernandez, Scott E. Henke, Ralph L. Bingham

National Quail Symposium Proceedings

Many studies have reported estimates of crippling loss (i.e., birds shot, noticeably or not, and not retrieved) for northern bobwhites (Colinus virginianus); however, comparisons among studies have been difficult because of a lack of standardized definitions and methods of calculation. The purpose of this paper was to: 1) provide a review of crippling loss of bobwhites across their geographic range, and 2) develop terminology that allowed for explicit discussion of crippling loss and facilitated comparison among studies. We also obtained an estimate of crippling loss for bobwhites in southern Texas using data from a larger study investigating the effects of …

Survival And Habitat Use Of Wild Pheasant Broods On Farmland In Lower Austria, Thomas H. Bliss, Brandon C. Anderson, Roger A.H. Draycott, John P. Carroll Jul 2017

Survival And Habitat Use Of Wild Pheasant Broods On Farmland In Lower Austria, Thomas H. Bliss, Brandon C. Anderson, Roger A.H. Draycott, John P. Carroll

National Quail Symposium Proceedings

Wild pheasants (Phasianus colchicus) have declined throughoutmuch of their European distribution. The influence of habitat composition on survival and habitat use of wild pheasant broods is not well understood, but is important for population management. We studied the brood-rearing ecology of pheasants using radio-tagged hens on a 2,400 ha farming estate in Lower Austria during 2001-2003. Brood survival , ≥ 1 chick surviving to 3 weeks, (n = 36) were: 74.4% (15.6 SE), 91.9% (7.8 SE), and 65.7% (13.8 SE), during 2001-2003, respectively. Complete brood loss (n = 7) occurred between 2 -17 days after hatching with predation (n = …

How To Re-Introduce Gray Partridges - Conclusions From A Releasing Project In Switzerland, Francis Buner Jul 2017

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 …

A Review Of Gray Partridge Restocking In The Uk And Its Implications For The Uk Biodiversity Action Plan, Stephen J. Browne, Francis Buner, Nicholas J. Aebischer Jul 2017

A Review Of Gray Partridge Restocking In The Uk And Its Implications For The Uk Biodiversity Action Plan, Stephen J. Browne, Francis Buner, Nicholas J. Aebischer

National Quail Symposium Proceedings

The gray partridge Perdix perdix has been the subject of many re-introduction projects throughout the world. In earlier attempts many releases simply aimed to increase the number of individuals for harvesting. This is very different from a conservation project aiming to establish a self-sustaining population. In recent decades, the gray partridge has declined severely in abundance and it is a species of conservation concern throughout Western Europe. Until now, gray partridge releasing projects have mainly focused on releasing large numbers of captive-reared individuals, of which few survive because of heavy predation and low breeding success. We reviewed the scientific and …

Summary Of Georgia's Bobwhite Quail Initiative 2000-2005., Reggie E. Thackston, Chris D. Baumann, Bobby T. Bond, Mark D. Whitney

National Quail Symposium Proceedings

Georgia’s Bobwhite Quail Initiative (BQI) has been a proactive effort to restore and improve habitat for northern bobwhite (Colinus virginianus; hereafter bobwhite) on private lands across a 15 county area of Georgia’s Upper Coastal Plain. Secondary objectives included improving habitat for certain songbirds, quail hunting and wildlife viewing. The BQI provided landowners/managers (Cooperators) with technical assistance, and through a competitive process, financial incentives for bobwhite habitat management. The Georgia General Assembly and Department of Natural Resources (DNR) Board initiated BQI in 1998 in response to hunter/constituent concern over declining bobwhite populations; and the Georgia DNR Wildlife Resources Division began implementation …

Long-Term Climate Trends And Northern Bobwhite Populations In South Texas, Jeffrey J. Lusk, Fred S. Guthery, Markus J. Peterson, Stephen J. Demaso Jul 2017

Long-Term Climate Trends And Northern Bobwhite Populations In South Texas, Jeffrey J. Lusk, Fred S. Guthery, Markus J. Peterson, Stephen J. Demaso

National Quail Symposium Proceedings

Because climate change and its associated weather changes may influence population trends of birds, we analyzed northern bobwhite (Colinus virginianus; bobwhite hereafter) age ratios and abundance in relation to climate trends during 1908-1997 in south Texas. Weather variables included regional mean temperature maxima for June, July, and August, and precipitation totals for autumn (Sep-Nov), winter (Dec-Feb), spring (Mar-May), and summer (Jun-Aug). Long-term temporal trends for these weather variables were estimated with a linear regression. Yearly weather data were used to predict bobwhite age ratios (juv/ad in autumn and winter) and abundance between 1908 and 1997 using neural network models. We …

Management Of Montezuma Quail In Texas: Barriers To Establishing A Hunting Season, Louis A. Harveson Jul 2017

Management Of Montezuma Quail In Texas: Barriers To Establishing A Hunting Season, Louis A. Harveson

National Quail Symposium Proceedings

Montezuma quail (Cyrtonyx montezumae) occur throughout the desert southwest, ranging from Vera Cruz, Mexico to southern Arizona, New Mexico, and western Texas. In Mexico, Montezuma quail are a protected species and in New Mexico and Arizona they are a harvested gamebird. The distribution of Montezuma quail has changed significantly during the past century. Currently Montezuma quail are limited in Texas to the Trans-Pecos with remnant populations in the Edwards Plateau. Although Montezuma quail are classified as a gamebird in Texas, seasons are currently closed. Recently, Texas Parks and Wildlife Department has expressed interest in opening the season on Montezuma Quail. …

Conservation Reserve Program Grasslands And Ring-Necked Pheasant Abundance In Minnesota, James F. Drake, Richard O. Kimmel, J. David Smith, Gary Oehlert

National Quail Symposium Proceedings

Ring-necked pheasant (Phasianus colchicus) abundance was measured on 15 study areas using roadside counts during the summers of 1990-1994 to examine possible relationships to permanent grasslands and 9 other cover types. The majority of permanent grasslands was enrolled in the Conservation Reserve Program (CRP) and likely would have been actively used for agriculture if not for the CRP. Roads were divided into 300 m segments and the proportion of each cover type was determined within 200 m and 800 m of each segment. A non-parametric procedure was used to determine the most significant predictors of number of pheasants observed on …

The Gwct Grey Partridge Recovery Programme: A Species Action Plan In Action, Nicholas J. Aebischer

National Quail Symposium Proceedings

In 1994, the UK government launched its Biodiversity Action Plan (BAP). Its list of BAP species included the grey partridge Perdix perdix, whose UK numbers had declined by 91% since 1962. The government set numerical targets in its grey partridge Species Action Plan, then nominated the Game & Wildlife Conservation Trust (GWCT) as lead partner to take the Plan forward. To this end, the GWCT has sought to raise awareness of the issues among the farming and shooting communities with promotional material. It has encouraged land and shoot managers to join its Partridge Count Scheme and established local Partridge Groups …

Impact Of Game Crops Intensification And Hunting Management On Red-Legged Partridge, Fancoise Ponce-Boutin, Jean-Francois Mathon, Tanguy Le Brun

National Quail Symposium Proceedings

In the French Mediterranean region, large cultivated areas have been abandoned. Matorrals (shrublands) then woodland successional stages replace the mosaic of habitats, favourable to the red-legged Partridge Alectoris rufa. An agro-environmental operation, consisting of development of areas devoted to game crops, allowed the reopening of these landscapes on the studied site. This we followed by the development of a hunting plan and operation. We tested the impact of these managements on the dynamics of the red-legged partridge abundance. Our research showed that the limitation of hunting bag has a strong impact on the densities of partridge in spring, whereas habitat …
