Effects Of Growing Season Fire On Northern Bobwhite Nest Site Selection And Survival, Sarah B. Rosche, Christopher E. Moorman, Christopher S. Deperno, Jeffrey G. Jones
National Quail Symposium Proceedings
Restoration and management of longleaf pine (Pinus palustris) communities necessitates frequent prescribed fire. Prior to human colonization of the southeastern United States thousands of years ago, longleaf pine forests burned primarily during the growing-season as a result of lightning-ignited fires. Growing-season prescribed fire may suppress woody vegetation and promote herbaceous groundcover better than dormant-season fire. Despite the potential ecological benefits of growing-season fire, many land managers use only dormant-season prescribed fire to avoid destruction of ground nests, including those from northern bobwhite (Colinus virginianus). Our objective was to determine bobwhite nest survival and nest-site selection in …

Patch Size And Nest Density Influence Nest Survival, Victoria L. Simonsen, Joseph J. Fontaine
National Quail Symposium Proceedings
Nest predation is the primary cause of avian nest failure and therefore an important driver of avian population growth. Studies indicate that landscape context plays an important role in nest success, and although this is widely attributed to changes in nest predator communities, landscape context also influences nest density which affects predator search area and effort. Much debate remains as to whether specifically the size of a habitat patch or the density of nests has the greatest effect on nest predation rates. We explored the interactions between landscape context, predator efficiency, and nest survival. Northern bobwhite quail (Colinus virginianus …

Estimates Of Northern Bobwhite Neonate Survival, Theron M. Terhune Ii, Richard B. Chandler, James A. Martin
National Quail Symposium Proceedings
Neonate survival is an important but poorly understood component of northern bobwhite (Colinus virginianus) population dynamics. We used a combination of thermal imagery (forward-looking infrared [FLIR]) and radio-telemetry to estimate survival from time of hatch to fall recruitment. During 2013 – 2015, we tracked bobwhites and captured broods at ~11 days of age using the corral technique. In addition to patagial tagging each neonate captured, we sutured radio-tags (0.76 g) on a subset of neonates (n = 56), and located them 3-4 times daily using radio-telemetry to determine fate and cause of mortality. We modified the Dail-Madsen …

Evaluating Two Trap-And-Release Methods For Bobwhites, Theron M. Terhune Ii
National Quail Symposium Proceedings
Numerous methods exist for capturing northern bobwhite (Colinus virginianus) including various net configurations and baited, wire-funnel traps. The latter represents the most commonly used technique whereby more than 97% of the studies in the current body of literature report using Stoddard’s (1931) standard quail trap for capturing bobwhites. Some researchers, however, employed multiple methods of capture for the same study. Regardless of the technique used, birds are either worked up directly in the field or held overnight and released the next day. Each of these approaches has their distinct advantages and limitations, and may vary with respect to …

Breeding Season Survival And Nesting Of Northern Bobwhite On Native Prairie Versus Traditionally Managed Conservation Areas In Southwestern Missouri, Thomas R. Thompson, Frank L. Loncarich, R. Kyle Hedges
National Quail Symposium Proceedings
Northern bobwhite (Colinus virginianus) management on Missouri Conservation Area lands has traditionally focused on providing an interspersion of grass, crop, old field and woody cover to enhance edge habitat often juxtaposed with disked idle areas and food plots. This traditional approach, or the Intensive Management Model (IMM), is often implemented with the goal of providing all essential habitat components within a 40-acre area. While this model can produce useable quail habitat in agriculture-dominated landscapes it may not be the most effective or efficient approach to producing quail in grassland-dominated landscapes found in southwest Missouri. Conservation area mangers for …

Northern Bobwhite Nest Site Selection In Field Borders, Danielle J. Berger, Jessica N. Piispanen, Tim F. Ginnett, Jason D. Riddle
National Quail Symposium Proceedings
Field borders are used to supplement early successional habitat critical for northern bobwhite (Colinus virginianus) nesting that is lost to modern intensive agricultural practices. The suitability of field border habitat for nesting may be affected by microhabitat characteristics at the site and patch scale and placement relative to various land-cover types at the landscape scale. We sought to determine whether bobwhite select nest locations at site, patch, and landscape scales. We collected microhabitat data (stem density, percent cover, and ground composition) and distance to land-cover type data (woody edge, crop, ditch, and road) from 26 bobwhite nests and …

Northern Bobwhite Home Range Sizes And Movements In South Texas, Katherine S. Miller, Fidel Hernández, Leonard A. Brennan, Randy W. Deyoung, X. Ben Wu
National Quail Symposium Proceedings
Northern bobwhites (Colinus virginianus) often have relatively small home ranges (1-km radius); however, occasional long-distance movements also have been recorded, which may help maintain connectivity and genetic diversity within and among populations. We quantified movements of radiocollared northern bobwhites on the King Ranch in South Texas, USA. For each bird we determined core area, home range (fixed kernel), mean movement rate, and maximum distance moved. We compared movements across age, gender, precipitation trends, and plant communities using Mann–Whitney U and Kruskal–Wallis tests. Almost half (44.7%) of the birds moved >400 m (max. distance moved) and 46 (16%) moved …

Foraging Behavior Of Northern Bobwhites In Relation To Resource Availability, Ryan S. Miller, William E. Palmer, Shane D. Wellendorf, L. Wes Burger Jr.
National Quail Symposium Proceedings
Distribution of food resources may influence northern bobwhite (Colinus virginianus) foraging decisions and demographic rates. We tested whether covey movements were sensitive to food availability by spreading sorghum (Sorghum bicolor) every 15 days at 3 rates; high rate (174 L/ha/yr), low rate (44 L/ha/yr), and no feed on 3 sections (~240 ha each) of Tall Timbers Research Station, 2009–2010. We measured sorghum availability spread along a 17 km feeding trail every 5 days. We determined seasonal (1 Nov - 15 Mar) home ranges of radio-tagged coveys (n = 89) and daily movement rates and home …

National Quail Symposium Proceedings
The group size of social animals and spatial structure of the environment can affect group behavior and movement decisions. Our objective was to investigate movement patterns and habitat use of northern bobwhite coveys (Colinus virginianus) of different size. Using radiotelemetry, we continuously monitored covey group size, daily movement, and habitat use on 12 independent 259-ha study areas in eastern Kansas, USA, during the winters between 1997 and 2000. We used correlated random walk models and fractal dimension models to determine if covey size affected movement characteristics or habitat selection. Intermediate-sized coveys (9–12 individuals, close to optimal covey size) …

Effects Of Supplemental Feeding On Breeding Season Home Ranges And Resource Selection Of Northern Bobwhites, Shane D. Wellendorf, William E. Palmer, Allen M. Bostick Iii
National Quail Symposium Proceedings
Providing supplemental food resources for northern bobwhite (Colinus virginanus) has been a common management practice for decades, but its impact on bobwhite home ranges sizes and space use has been debated. Between 2001 and 2007, we established a 397 ha fed study area on Tall Timbers Research Station, which received grain sorghum biweekly along a 19.5 km feed trail. An adjacent 465 ha area was treated as a control with no supplemental food resources. Radio-tagged wild bobwhites were located 3 – 5 times each week throughout the breeding season and we used these locations to calculate home ranges …

Winter Survival And Habitat Selection By Translocated Northern Bobwhite In The New Jersey Pine Barrens: Preliminary Results, Kaili R. Stevens, Philip M. Coppola, Christopher K. Williams, Theron M. Terhune Ii, John P. Parke, John Cecil
National Quail Symposium Proceedings
Northern bobwhite (Colinus virginianus) populations have been experiencing precipitous range-wide declines for more than 50 years; some of the steepest declines occurring in the Mid-Atlantic states. These declines are largely attributed to habitat deterioration from urban sprawl, change in forest management, and intensive farming. This ongoing study aims to evaluate the efficacy of translocating wild bobwhites into the New Jersey Pine Barrens as a means to restore their historic populations. Translocation has proven relatively successful in augmenting bobwhite populations in other regions as well as restoring populations of gallinaceous species. This portion of the study aims to investigate …

National Quail Symposium Proceedings
Northern bobwhite (Colinus virginianus) have declined precipitously since the 1960s, largely due to habitat deterioration and changes in land use; some of the highest declines have been observed in the Mid-Atlantic States. In other regions, attempts to augment bobwhite populations have been relatively successful using translocation. As part of a long-term restocking program, focal areas for translocation in the mid-Atlantic region were identified by biologists at a National Bobwhite Conservation Initiative (NBCI) workshop. The objective of this project is to evaluate translocation to restore bobwhite populations in the New Jersey Pine Barrens, a focal area designated with a …

Parent-Reared Bobwhite Survival In The Texas Rolling Plains, Mark A. Thomas, C. Brad Dabbert
National Quail Symposium Proceedings
Considerable research has been accomplished over the past 6 decades on the possible reasons for decline in the northern bobwhite (Colinus virginianus), henceforth known as the bobwhite. Restoring or restocking bobwhite populations by augmentation in areas that once held significant numbers has been a focus for many wildlife agencies and managers. Three main methods for augmentation of bobwhites currently exist: release of pen-raised birds, release of juvenile birds reared by Surrogator®, and translocation of wild bobwhites from one area to another. Of these 3 methods, only translocation has accomplished the goal of reestablishing bobwhite populations. Recently …

Testing Northern Bobwhite Reintroduction Techniques In The Northern Edge Of Their Range, William Macaluso, Christopher K. Williams, Theron M. Terhune Ii
National Quail Symposium Proceedings
Pen-rearing young frequently fails as a reintroduction technique in game birds because of low postrelease survival rates in the wild. This may be caused by a combination of poor genetics from domestication, unhealthy birds, birds that do not exhibit wild behavior, or birds that are unfamiliar with their surroundings after hard releases. Recent research suggests that parent-rearing, involving pre- and posthatch imprinting of wild-strain northern bobwhite (Colinus virginianus) chicks by adults, may be a viable option for restoring populations. Imprinting potentially causes reintroduced birds to exhibit more natural behavior. We tested this method against a slightly modified traditional …

The Effect Of Age-At-Release On Survival Of Adoptive Parent-Reared Bobwhite Chicks, Kyle D. Lunsford, Theron M. Terhune Ii, James A. Martin
National Quail Symposium Proceedings
Translocation of wild northern bobwhites (Colinus virginianus) to restore local populations is a viable conservation tool under some scenarios; however, the supply of wild bobwhites is limited. Bobwhites can be artificially propagated, as an alternative to translocation, using methods that mimic natural brood-rearing. The parent-rearing adoptive process (PRAP) uses wild-strain bobwhite adults to brood and foster newly hatched wild-strain chicks in outdoor aviaries that emulate a natural environment. Adoptive parent-reared bobwhites have higher survival rates than artificially-reared bobwhites but only a single age-of-release (i.e., 6-weeks) has been tested. We tested the effect of age-at-release (3, 6, and 9-weeks) …

Experiences In Northern Bobwhite Propagation And Translocation In Ohio, 1978-2012, Mark J. Wiley, Nathan J. Stricker
National Quail Symposium Proceedings
Ohio once boasted a population of 7 million northern bobwhites (Colinus virginianus). Catastrophic blizzards during 1976–1977 and 1977–1978 brought winter quail mortalities of 85% and 80%, respectively. Ohio’s bobwhite population was 430,000 in 1978, a 90% reduction from 1976. Remnant quail populations were small, isolated, and incapable of rapid recovery. The Ohio Department of Natural Resources (ODNR) initiated a statewide stocking effort to expedite population growth. The ODNR chose to propagate wild quail in captivity and release first-generation progeny (F1). Throughout 1980–1986, the ODNR released 65,000 F1 quail statewide. The ODNR monitored population response with North American Breeding …

National Quail Symposium Proceedings
The National Bobwhite Conservation Initiative (NBCI 2.0) is a range-wide plan for recovering northern bobwhites (Colinus virginianus; hereafter, bobwhite[s]). Using geospatial analysis informed by expertise from practitioners, the plan categorizes landscapes into restoration potential by weighing biological constraints and opportunities such that targeted habitat management will produce bobwhite population growth. A fundamental assumption of the NBCI 2.0 for achieving recovery goals is that bobwhite source populations currently exist on the landscape at densities necessary to (re)colonize newly established or improved habitat. However, we have found that these source populations can be very low or non-existent, especially in northern …

The majority of today’s youth have the ability to utilize consumer technology on a regular basis. This access has exacerbated the disconnect between adolescents and the natural environment by reducing the amount of time spent outdoors. To compound this disconnect, the continued use of traditional classroom settings along with the ‘‘sit-and-get’’ style of facilitation, widens the gap between inert knowledge and applied knowledge. The transformation from theory to practice witnessed in outdoor science, technology, engineering and mathematics (STEM) education has been shown to foster the assimilation and retention of STEM concepts. Therefore, educational institutions have begun to cultivate the implementation …

Response Of Grassland Birds To Agricultural Intensity At Different Spatial Scales In Texas, Anna Matthews, M. Clay Green, James Giocomo
National Quail Symposium Proceedings
The decline in grassland birds is often associated with habitat loss due to intensity of conversion to agricultural lands and the alterations of natural disturbances. We sought to identify agricultural effects at differing scales that correlate to Texas grassland bird abundance, especially northern bobwhite (Colinus virginianus). Ninety-five roadside routes were surveyed in 20 Texas counties ranging from the Oklahoma border to the coastal plains. We conducted point counts in May and June from 2013 to 2016. To estimate the coarse effects of agriculture on bird abundance at a county level, we used number of cattle and area of …
