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, …

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 …

Fate Of Captive-Reared Bobwhite Quail Released In Central Kentucky
<p>The fate of pen-raised bobwhite quail (Colinus virginianus) released onto two farms (Site 1 and 2) and a reclaimed coal surface mine (Site 3) in south-central Kentucky during the summers of 2008 and 2009 was assessed. Of the 57 bobwhite quail radio-tagged and released in this study, the fate of …

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 …

Modified postnatal social experience alters intersensory development of bobwhite quail chicks
… study utilized a precocial avian infant, the bobwhite quail (Colinus virginianus), to explore 1) what types of postnatal social experience young chicks require to successfully pair sights and sounds and 2) when these experiences need to occur to maintain species-typical intersensory …

Auditory and visual determinants of maternal preference in bobwhite quail neonates
… the control of filial behavior was examined in bobwhite quail chicks during the first 4 days of postnatal life. Previous research has revealed that bobwhite quail hatchlings are differentially responsive to their species-specific maternal call in the period right before and immediately following …

Neural Plasticity and the Development of Intersensory Functioning in Bobwhite Quail (Colinus virginianus)
… visual responsiveness to maternal cues in bobwhite quail chicks. Results revealed that the pattern of neuronal organization and postnatal behavior was influenced by the amount of prenatal visual experience subjects were provided. Specifically, chicks exposed to 240 min of prenatal visual …

Social context affects behavioral responsiveness to maternal alarm calls in Bobwhite quail chicks
… of maternally naive, incubator-reared bobwhite quail chicks. Experiment 1 assessed alarm call responsiveness in socially-reared, socially-tested hatchlings across the first 96 hours following hatch. No significant age effects were revealed. Hatchlings tested at 24 hours did not differ …

The role of stimulus matching in the development of intersensory perception in bobwhite quail
… cues in directing the perceptual preferences of bobwhite quail chicks. Results reveal that chicks prefer postnatal stimulus cues that matched the particular type of prenatal stimulation they received as embryos over stimulus cues that match the amount of prenatal stimulus cues they received. …

Effects of altered prenatal auditory experience on postnatal auditory preferences in bobwhite quail chicks
… present study analyzed the acoustic features of bobwhite quail embryonic vocalizations emitted during the final 36 hours prior to hatching. Using software for sound spectrographic analyses, information was collected on the average fundamental frequency, frequency modulation and range, repetition …

Effects of early and delayed visual experience on intersensory functioning in bobwhite quail chicks
… of avian embryos and hatchlings. Normally reared bobwhite quail chicks are known to require only maternal auditory cues to direct their social preferences in the first days following hatching. However, by 3 days following hatching quail chicks require both auditory and visual cues to direct their …

The effects of augmented prenatal visual stimulation on postnatal perceptual responsiveness in Bobwhite quail
The present study examined whether previously reported effects of altered prenatal sensory experience on the subsequent acceleration of intersensory functions are mediated by mechanisms sensitive to the overall amount of stimulation. Results reveal that chicks exposed to augmented amounts of …

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 …

Type and amount of prenatal auditory experience alters postnatal perceptual responsiveness in bobwhite quail
Bobwhite quail embryos were exposed to 5 or 10 min/hr of either bobwhite chick contentment calls or bobwhite chick distress calls. Results revealed that embryos exposed to 5 or 10 min/hr of distress calls continued to respond to maternal auditory cues into later stages of postnatal development in …
