Comparing The Accuracy Of Egg Candling And Egg Flotation To Estimate The Hatching Date Of Northern Bobwhite Clutches, Byron R. Buckley, Alicia K. Andes, C. Brad Dabbert
National Quail Symposium Proceedings
Floating and candling avian eggs to assess hatch dates has been used successfully to estimate hatch dates for wild bird clutches for decades. However, there is a dearth of information assessing the accuracy of these techniques to estimate northern bobwhite (Colinus virginianus) hatch dates. We captured and fitted a hen bobwhites with very high frequency transmitters during January and February of 2011–2012. We monitored each bird twice weekly until nesting was initiated. We searched for the nest while the hen was away from the nest (i.e., feeding) to reduce potential abandonment. We used egg floatation and egg candling …

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) …

Effect Of Temperature And Wind On Metabolism Of Northern Bobwhite In Winter, L. Wes Burger Jr., Thomas V. Dailey, Mark R. Ryan, Eric Kurzejeski
National Quail Symposium Proceedings
Northern bobwhite (Colinus virginianus) are widely distributed across more than half of the United States, and extending into Canada and Mexico. Within this distribution they tolerate a wide range of climatic conditions and thermal stress. Annual variation in weather can produce dramatic short-term population fluctuations, particularly in the northern portion of the distribution. To better understand effects of thermal stress on energy requirements of bobwhite, we measured roosting metabolic response to cold stress and wind speed using open respirometry in a closed-circuit wind tunnel. Oxygen consumption was measured for 8 winter-acclimated captive bobwhites at each of 8 temperatures …

Genetic Diversity And Relatedness Within And Among Northern Bobwhite Coveys In South Texas, Katherine S. Miller, Leonard A. Brennan, Randy W. Deyoung, Fidel Hernández, X. Ben Wu
National Quail Symposium Proceedings
Although biologists have studied northern bobwhite (Colinus virginianus) genetic diversity and population structure, there is little known about the genetic diversity, structure, and relatedness of their winter coveys. Both flexible mating strategies and the fall shuffle may have implications for inbreeding and genetic diversity in northern bobwhite populations. Our goal was to determine genetic diversity and relatedness for coveys on a private ranch in Jim Hogg County in South Texas. During the 2010–2011 and 2011–2012 hunting seasons, 96 northern bobwhites were sampled from 29 coveys. We analyzed 11 northern bobwhite microsatellite DNA loci, measured genetic structure with an …

Effect Of Field Trials On Northern Bobwhite Survival And Hunt Quality On Dixie Plantation, D. Clay Sisson, Theron M. Terhune Ii
National Quail Symposium Proceedings
The potential negative effects of horseback field trials on survival and post trial hunting quality of northern bobwhites (Colinus virginianus) have long been debated. Recent acquisition of Dixie Plantation (3,650 ha) by Tall Timbers Research Station provided a unique opportunity to evaluate this interaction as Dixie has been home to the Continental Field Trial since 1937. We monitored radio-tagged bobwhites annually (n = 183; ~20 coveys during fall/winter) on a core study area (640 ha) upon which a portion of the field trial was conducted during January 2015 & 2016. We estimated Kaplan-Meier survival of radio-tagged bobwhites …

Evaluating The Impacts Of Hunting Paths On Northern Bobwhite Survival, Economic Costs, And Hunter Satisfaction, Seth Wood, Theron M. Terhune Ii, James A. Martin
National Quail Symposium Proceedings
The amount and spatial configuration of habitat is known to influence the abundance, movements, resource use, and persistence of many species. As such, land managers must be judicious in their application of management actions to minimize its impact on wildlife while concurrently providing recreational opportunities. Mowing or roller-chopping is a common management technique implemented on intensively managed northern bobwhite (Colinus virginianus) plantations to increase hunter accessibility, provide travel corridors for pointing dogs, manage vegetation succession, among other benefits. Managers typically create hunting paths in a grid pattern at 30 ft spacing resulting in approximately 35% of vegetation removed …

Refining The Hunting Zone Of Hunter-Covey Interface Models, James A. Martin, Diana J. Mcgrath, Seth Wood, Theron M. Terhune Ii
National Quail Symposium Proceedings
Regulating harvest is important to sustain northern bobwhite (Colinus virginianus) populations. Direct measures to control harvest such as setting fixed proportions (i.e., percent of fall population) are not typically feasible, thus, indirect measures (e.g., managing access, season length) are more commonly used. However, these measures are predicated on relationships between hunter effort and kill rate (K) which is a function of several parameters including: the probability of encountering a covey (p), where p is a function of the effective area hunted (a) divided by that available (A). Thus, a, …

Evaluating Hunting Success Of Pen-Reared And Wild Northern Bobwhite In A Reclaimed Kentucky Mineland, Jeremy P. Orange, John M. Yeiser, Danna L. Baxley, John J. Morgan, Ben A. Robinson
National Quail Symposium Proceedings
Northern bobwhites (Colinus virginianus) have experienced severe population declines across their distribution. In order to address population declines and to continue providing hunting opportunities, multi-state efforts have been undertaken to stabilize and restore bobwhite populations. Ongoing efforts using the National Bobwhite Conservation Initiative’s quail focus area approach have so far demonstrated success throughout Kentucky. However, population increases in the Peabody Bobwhite Focal Area, in western Kentucky, have not been correlated to increases in perceived hunter success. Consequently, some sportsmen question the effectiveness of focal area conservation. In response to hunter concerns, we tested dog hunting ability with wild …

Hunter success is a critical measure of northern bobwhite (Colinus virginianus) restoration. Understanding the factors influencing hunter success can guide wildlife agencies in efforts to improve success and satisfaction and sustain hunter support of conservation initiatives. We compared use of vegetation types by radiomarked bobwhite (n = 30 coveys) and hunting dogs (n = 241) equipped with Global Positioning System collars during the 2014–2015 quail hunting season on Peabody Wildlife Management Area in western Kentucky. We surveyed hunting parties (n = 252) immediately after their hunt to determine success (flushed bobwhite) and gather hunt-party characteristics. …

Hunter-Covey Interactions Using Pointing Bird Dogs, Theron M. Terhune Ii, Diana J. Mcgrath, Seth Wood, James A. Martin
National Quail Symposium Proceedings
Hunting northern bobwhites (Colinus virginianus) with pointing dogs is a long-standing tradition in the Southeastern United States. Despite this rich hunting legacy, a paucity of empirical, behavioral information exists on the interaction between bobwhite coveys, pointing dogs and humans. As such, the efficiency of using pointing dogs to locate bobwhite coveys or an individual covey’s behavioral response to hunting is poorly understood. During 2013 – 2015, we conducted hunts (n = 192) by mode of foot on Tall Timbers Research Station (TTRS, ~1,570 ha) in Leon County, Florida and horseback on a private property (2,023 ha) in …

Distance Sampling To Assess Post-Grazing Northern Bobwhite Recovery In South Texas, Rachel A. Smith, Leonard A. Brennan, Fidel Hernández, Humberto L. Perotto-Baldivieso
National Quail Symposium Proceedings
Northern bobwhite (Colinus virginianus) require habitat structure with substantial grass cover for nesting, predator avoidance, and thermal refuge. During the past 2 decades, many land managers have reduced or completely eliminated livestock across South Texas rangelands with the goal of improving bobwhite habitat. How bobwhites respond to post-grazing habitat recovery is unknown. Our objective is to investigate how bobwhites respond to the vegetative changes following removal of grazing. Our study is being conducted on a private ranch in Jim Hogg County, Texas and involves 3 different areas of post-grazing habitat recovery: a 1,246 ha area rested from grazing …

The Efficacy Of Gopro Cameras To Account For Northern Bobwhites Flushed, But Undetected During Aerial Surveys, Andrea Bruno, Leonard A. Brennan, Andrew N. Tri, Habin Su
National Quail Symposium Proceedings
Estimating density and abundance is central to wildlife conservation for planning and decision-making purposes. Development of model-based techniques, such as distance sampling, allows researchers to estimate density with the inclusion of detection probabilities. However, the reliability of estimates obtained through this method are dependent upon the satisfaction of underlying assumptions, the most critical being that objects at zero distance from the observer be detected with 100% certainty. Conventional distance sampling, where line transects are traversed from an aerial platform, is a commonly used method to estimate northern bobwhite (Colinus virginianus) density over large, open areas. The restricted observer …

Comparison Of Dog Surveys And Fall Covey Surveys In Estimating Fall Population Trends Of Northern Bobwhite, Evan P. Tanner, R. Dwayne Elmore, David K. Dahlgren, Craig A. Davis, Samuel D. Fuhlendorf
National Quail Symposium Proceedings
The use of fall covey surveys to monitor population trends for northern bobwhite (Colinus virginianus; hereafter bobwhite) have been widely used in bobwhite research. Estimates of relative abundance from this monitoring technique are often important in assessing population responses to management practices or annual variation. However, conducting covey call surveys is labor intensive and typically can only be conducted during a narrow time frame. The use of dogs as a research tool may offer an efficient alternative to monitor bobwhite population trends. While dogs have been used in research for many other gallinaceous species, their application for bobwhite …

Retention And Efficacy Of Citizen Scientist Volunteers Of The Texas Quail Index, Kelly S. Reyna, Dale Rollins
National Quail Symposium Proceedings
The Texas Quail Index (TQI) was a 5-year, science-based project that utilized citizen scientists to collect data in the field, including 5 indices of bobwhite abundance in the spring, and 3 indices of bobwhite abundance in the fall. Over the course of the study, 84% of all volunteers dropped out of the program and <8% of all data sets were complete. Accordingly, we surveyed the volunteers by mail to determine the rate and cause of participation decline and to identify characteristics of a reliable volunteer. Results indicated that annual volunteer participation rate declined more rapidly as time and labor requirements increased. Similarly, 74.3% of survey respondents who dropped out of the study reported leaving because the project required too much time and work. Motives may have contributed to the volunteer attrition as 72% of volunteers joined the program to learn more about quail management; however 71% of those that left the program reported not gaining knowledge in that area. We recommend that project designs, for citizen-science projects, should incorporate the motives of volunteers and recruit those whose motives best align with project goals. We also recommend that citizen-science coordinators keep volunteer tasks short and within the interest of the volunteer, to increase retention. Finally, we recommend stipends for volunteers on large-scale, laborious projects.

Use Of Spring Whistle Counts To Predict Northern Bobwhite Relative Abundance, D. Clay Sisson, Theron M. Terhune Ii
National Quail Symposium Proceedings
Spring whistle counts are commonly used to index northern bobwhite (Colinus virginianus) breeding populations and make inference about relative autumn abundance. They are relatively cheap and easy to implement and provide the advantage of surveying bobwhite populations from multiple points daily and early in the year. This could prove useful on properties available for potential lease, purchase, or as translocation sites; as well as to monitor population trends. Our objective was to determine whether spring whistle counts reliably forecast autumn covey numbers on a wide range of sites, years, and densities on 6 properties in southwestern Georgia from …

Statistical Population Reconstruction Using Wings From Harvested Northern Bobwhites Can Inform Management, Theron M. Terhune Ii, Kristen M. Malone, D. Clay Sisson, James A. Martin
National Quail Symposium Proceedings
Despite the widespread collection wings from harvested northern bobwhite (Colinus virginianus) by state wildlife agencies and private entities, age-at-harvest information has been largely underutilized for guiding management decisions for this species. Statistical population reconstruction (SPR) techniques can use age-at-harvest information and provide a valuable tool for monitoring trends and the status of bobwhite (and other game bird) populations. However, SPR has not been applied to bobwhite. We evaluated the utility of statistical population reconstruction models, which have been applied successfully to other species (e.g., elk, Cervus elaphus; blacktailed deer, Odocoilues hemonius; and greater sage-grouse, Centrocercus urophasianus …

The decades long decline in grassland avian populations is ultimately attributed to changing land use throughout the United States. Due to their economic importance and status as a healthy grassland indicator species, attention focused towards land management for northern bobwhite (Colinus virginianus) benefits other grassland vertebrate and invertebrate species. Land restoration practices offer opportunities to mitigate the declines in northern bobwhite populations. While several studies focus on restoring land for northern bobwhite, this study addressed the effectiveness of such restoration practices. We radio-marked female bobwhite from April to July 2016 and located the birds every three to five …

Triple Brood Production By Northern Bobwhites, D. Clay Sisson
National Quail Symposium Proceedings
Most aspects of northern bobwhite (Colinus virginianus) life history are well understood and well documented, including their ability to ‘‘double brood’’ (defined as the same hen successfully hatching 2 broods during a single nesting season). Less understood are the ability and/or prevalence of ‘‘triple broods’’ in the life history of bobwhites. Occasional citing in the literature of triple brooding is often unclear as to whether reference is being made to the attempt at hatching 3 broods in a season or actually doing so. This confusion stems from the interchanging use of the words brood and clutch. While Webster …

Influence Of Northern Bobwhite Nest Site Selection On Nest Survival In An Agricultural Landscape, Andy D. Richardson, Christopher E. Moorman, Craig Harper, Mark D. Jones, Benjy M. Strope
National Quail Symposium Proceedings
Working farms provide excellent potential for conserving northern bobwhite (Colinus virginianus) habitat in agricultural landscapes. Managing for areas of early successional vegetation can increase bobwhite abundance with little reduction in crop production on working farms, but the mechanisms behind the increase is not well known. Our objective was to determine nest site characteristics that may predict nest initiation and survival on agricultural lands to inform future management activities. We radio-collared 241 wild bobwhite on 1 farm with and 2 farms without bobwhite habitat management in southeastern North Carolina. Study sites consisted of a 1,740-ha farm with 9% of …
