Landscape genetics of northern bobwhite and swamp rabbits in Illinois
Northern bobwhite (Colinus virginianus) and swamp rabbits (Sylvilagus aquaticus) are species both strongly influenced by habitat loss and fragmentation in agricultural landscapes. Population declines for the bobwhite and the paucity of information regarding swamp rabbit prevalence add uncertainty …

Spring Dispersal and Breeding Ecology of Northern Bobwhite in Southwest Ohio
<p>Northern bobwhites are a popular upland game bird species with economic and social importance. Despite nearly a century of research, population declines continue at state and national scales. Precipitous population declines and range-contractions in the Midwest have been caused by land-use …

Landscape Level Evaluation of Northern Bobwhite Habitats in Eastern Virginia Using Landsat TM Imagery
Northern bobwhite (<I>Colinus virginianus</I>) are important game birds associated with early successional habitats across the southeastern United States. In the past 30+ years there has been an almost universal decline in bobwhite population numbers despite a long history of management. The …

Field evaluation of the northern bobwhite habitat suitability index model with implications for the conservation reserve program
A field evaluation of a modified version of the northern bobwhite (Colinus virginianus) Habitat Suitability Index (HSI) model was conducted using habitat and relative abundance data from 121 sites distributed throughout Halifax County, Virginia, 1986-1991. Model output and the index of relative …

The role of invertebrates in the diet, growth and survival of Northern bobwhite, Colinus virginianus, chicks in the Southeastern United States
… are the primary component in the diet of northern bobwhite, Colinus virginiamus, chicks during the first two weeks of life. Despite this, few studies have described the composition of invertebrates in the diet of wild chicks and none have examined their effects on chick-growth and …

Modeling Detection and Density Using Distance Sampling for Three Priority Grassland Bird Species in Texas - Northern Bobwhite (Colinus virginianus), Eastern Meadowlark (Sturnella magna), and Painted Bunting (Passerina ciris)
… loss of native grasslands. These species are the Northern Bobwhite (Colinus virginianus), Eastern Meadowlark (Sturnella magna), and Painted Bunting (Passerina ciris). Due to this, accurate density and abundance estimates are critical for management of these species. This 5-year study identified …

Grassland bird associations in a managed agricultural matrix
… nest ecology, Dickcissel fledgling ecology, and Northern Bobwhite landscape-level associations. Strip-transect surveys showed that Red-winged Blackbird (43%) and Dickcissel (42%) dominated bird communities, but other abundant species included Eastern Meadowlark, Indigo Bunting, Mourning Dove, and …

Influence of Vegetation Structure on Density of Northern Bobwhites (Colinus Virginianus) on a Tallgrass Prairie in Southwestern Missouri
Northern bobwhite quail (Colinus virginianus), populations have declined noticeably since the 1960s. The role of annual habitat variability on quail density in a tallgrass prairie setting is poorly understood. To provide insight into the efficacy of tallgrass prairie management in southwestern …

Habitat relationships of bobwhite quail and cottontail rabbits on agricultural lands in Halifax County, Virginia
… uses in the Virginia Piedmont during 1986-1987. Bobwhites and cottontails were censused and the associated habitat components quantified at 2 scales: macro-scale at 121 road transect stations, and a micro-scale at 87-foot transect stations. Additionally, the quail's immediate habitat was measured …

Using Remote Sensing Data to Predict Habitat Occupancy of Pine Savanna Bird Species
… Bachman's Sparrow (BACS; Peuacea aestivalis), Northern Bobwhite (NOBO; Colinus virginianus), and Red-Cockaded Woodpecker (RCW; Dryobates borealis) across Georgia. I assessed the performance of satellite imagery in predicting habitat occupancy of these pine savanna species and its potential for …

Cultivation of Eimeria Dispersa in Bobwhite Quail Embryos
… sporulated oocysts of Eimeria dispersa from the Bobwhite quail (Colinus virginianus), to study the endogenous development of E. dispersa in Bobwhite quail embryos, and to examine the cross-transmission properties of this species for turkeys, chickens, and Japanese quail. Procedure. Oocysts, …

Response of avian, arthropod, and vegetation communities to mid-contract management in Conservation Reserve Program tall fescue monocultures
Northern bobwhite (hereafter, bobwhite; Colinus virginianus) have experienced long-term declines in population abundance throughout most of their breeding range. In 2004, the United States Department of Agriculture (USDA) authorized mid-contract management (MCM) to restore early successional plant …

Habitat use, population size, and nesting ecology of conservation priority bird species using restored fields in agricultural landscapes
… the population goal for the Field Sparrow and Northern Bobwhite. Lastly, analyses related to my third question demonstrated that nesting Bell’s Vireos and Willow Flycatchers selected habitat that increased nest survival, but not number of young fledged from successful nests, in these …

Using Passive Acoustic Monitoring to Estimate Bird Community Response to Land Management in Southeastern Georgia
… as Bachman's Sparrow (Peucaea aestivalis) and Northern Bobwhite (Colinus virginianus). However, habitat use is likely contingent on specifics of land-use practices, especially those that could alter understory vegetation. My first research objective was to use autonomous recording units (ARUs) …
