Water Restriction Effects on Northern Bobwhite Reproduction
The Journal of Wildlife Management, 1991We compared the reproductive function of domestic and wild-caught northern bobwhites (Colinus virginianus) receiving ad libitum water with those receiving the minimum required for mass stasis under simulated spring and summer conditions. Relative gonad size, expressed as a percentage of body mass, was similar (P≥0.10) between domestic and wild-caught ...

Essential Amino Acids in Northern Bobwhite Foods
The Journal of Wildlife Management, 1994Frequent population declines, high dietary requirements for protein, and the low quality of proteins in agricultural grains led us to hypothesize that essential amino acid (EAA) deficiencies were common in northern bobwhite (Colinus virginianus) foods.

REPRODUCTION BY NORTHERN BOBWHITES IN WESTERN OKLAHOMA
Journal of Wildlife Management, 2005Abstract We studied northern bobwhites (Colinus virginianus) in western Oklahoma, USA, during the nesting seasons of 1992–2001. We obtained latitude-specific information on nesting biology and tested hypotheses on the cause of declines in clutch size with progression of the nesting season and on the phenological relation of first, second, and third ...

Optimal group size and northern bobwhite coveys
Animal Behaviour, 2003Abstract Northern bobwhite, Colinus virginianus , form social units, called coveys, during the nonbreeding season (approximately September–April). Because the evolutionary advantage of this behaviour is generally unknown, we used controlled group size manipulations within an aviary to investigate whether group size influences (1) the time that the ...

EXPERIMENTAL INFECTION OF NORTHERN BOBWHITE QUAIL WITH BORRELIA BURGDORFERI
Journal of Wildlife Diseases, 1994Four-week-old northern bobwhite quail (Colinus virginianus) were inoculated subcutaneously with 10(6) organisms from a low passage culture of Borrelia burgdorferi. Blood was collected weekly for culture, antibody detection, and immunoblot analysis. Three weeks postinoculation, viable spirochetes were isolated from the blood of one bird, but not from ...

ECOLOGY OF HELMINTH PARASITISM IN BOBWHITES FROM NORTHERN FLORIDA
Journal of Wildlife Diseases, 1991Examination of 700 northern bobwhites (Colinus virginianus), 50 each February from 1971 through 1984, from Tall Timbers Research Station, Leon County, Florida, disclosed 15 species of helminth parasites. Nine species (Raillietina cesticillus, R. colinia, Aproctella stoddardi, Cheilospirura spinosa, Cyrnea colini, Dispharynx nasuta, Heterakis isolonche,

ACUTE EFFECTS OF AFLATOXIN ON NORTHERN BOBWHITES (COLINUS VIRGINIANUS)
Journal of Wildlife Diseases, 2013Aflatoxin is a widely occurring and harmful mycotoxin produced by strains of Aspergillus spp. growing on vegetable matter. We investigated the concentration of aflatoxin needed to impair normal physiologic responses and induce acute morbidity and mortality in Northern Bobwhites (Colinus virginianus). Ten wild-caught adult bobwhites (five males and five

Restoration Techniques for Northern Bobwhites
Isolated populations of northern bobwhites (Colinus virginianus) have declined causing many quail managers to attempt population restoration by releasing captive-reared bobwhites or translocating wild bobwhites. I evaluated three restoration techniques: (1) release of captive-reared bobwhites, (2) translocation of bobwhites from high densities to low ...openaire +1 more source
Vegetation and predator interactions affect northern bobwhite behavior
The Journal of Wildlife Management, 2018ABSTRACTAnti‐predator behavior can be costly to prey species and the consequences of these decisions may affect survival. Interactions between humans and hunted species can lead to behavioral shifts in the animal that affect hunter satisfaction and possibly fitness of the animals.

Radiotelemetry studies: are we radio-handicapping northern bobwhites?
Wildlife Society Bulletin, 2004Having become suspicious of telemetry-based survival rates reported for northern bobwhites (Colinus virginianus), we surveyed the published record to determine whether reported survival rates were consistent with empirical expectations of production, for which there exists a vast database.
