SURVEILLANCE FOR SELECTED PATHOGENS AND PARASITES OF NORTHERN BOBWHITE (COLINUS VIRGINIANUS) FROM WESTERN OKLAHOMA, USA, 2018–20

Journal of Wildlife Diseases
: The Northern Bobwhite (Colinus virginianus) has been undergoing a range-wide population decline. Potential causes for declines across its historic range have been investigated for decades and include habitat loss and fragmentation and a variety of ...

Northern bobwhite foraging response to hunting

The Journal of Wildlife Management, 2018
ABSTRACTPrey species must consistently balance the need for resource acquisition with the threat of predation. This balance is particularly true for gallinaceous birds, such as the northern bobwhite (Colinus virginianus), which are ground foragers and are often exposed to increased predation risk compared to arboreal foragers.

IDENTIFYING PREDATORS AT NORTHERN BOBWHITE NESTS

Journal of Wildlife Management, 2005
Abstract We identified nest predators of northern bobwhites (Colinus virginianus) on private lands in northern Florida and southern Georgia, USA, using continuous infrared micro-video cameras, 1999–2001, and compared these results to predictions based on diagnostic sign at nests.

Water Restriction Effects on Northern Bobwhite Reproduction

The Journal of Wildlife Management, 1991
We 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, 1994
Frequent 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.

Northern Bobwhite Non‐Breeding Habitat Selection in a Longleaf Pine Woodland

Journal of Wildlife Management, 2020
Efforts to halt the decline of the northern bobwhite (Colinus virginianus; bobwhite) across its distribution have had limited success. Understanding bobwhite habitat requirements across the annual cycle and at varying scales is essential to aid efforts ...

REPRODUCTION BY NORTHERN BOBWHITES IN WESTERN OKLAHOMA

Journal of Wildlife Management, 2005
Abstract 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, 2003
Abstract 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 ...

Nesting Ecology of Northern Bobwhite on a Working Farm

, 2020
Creating early successional vegetation on working farms can increase northern bobwhite (Colinus virginianus; hereafter, bobwhite) abundance with little reduction in crop production, but specific effects of field border establishment on bobwhite nesting ...

EXPERIMENTAL INFECTION OF NORTHERN BOBWHITE QUAIL WITH BORRELIA BURGDORFERI

Journal of Wildlife Diseases, 1994
Four-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 ...
