Bobwhite, Colinus virginianus, as Host for Heterakis and Histomonas

Journal of Wildlife Diseases, 1971
Bobwhites were experimentally infected with Histomonas meleagridis and Heterakis gallinarum. Chickens and turkeys were similarly infected for comparison. Although the bobwhites were nearly as susceptible to Histomonas infections as were New Hampshire chickens, and more susceptible to tissue invasion, clinical histomoniasis was much less severe than in ...

Experimental West Nile Virus Infection in Northern Bobwhite Quail (Colinus virginianus)

Avian Diseases, 2021
West Nile virus (WNV) has been implicated in regional declines of numerous North American bird species, although its potential impact upon many species, including some game birds, remains unknown. Specifically, information about susceptibility to infection and infection outcome are crucial to assessing health risks.

Ten microsatellite loci from Northern Bobwhite (Colinus virginianus)

Conservation Genetics, 2008
Ecological studies using microsatellite data often require the selection of an optimal marker set for use in parentage and relatedness inference. Commonly, this requires a candidate pool of microsatellite markers from which several are selected to ensure data are acquired efficiently and accurately.

Successive reversal learning in the bob-white quail (Colinus virginianus)

Animal Behaviour, 1967
Four Bob-white quail (Colinus virginianus) were run on a series of twenty-five reversals of a discrimination involving simultaneous presentation of horizontal and vertical stripes. Analysis of five reversal blocks revealed a decrease in errors to criterion between the first and last block (t=2·50 ...

Distribution and excretion of hexachlorobenzene in bobwhite (Colinus virginianus)

Journal of Toxicology and Environmental Health, 1983
After a single dose of [14C]hexachlorobenzene (HCB) via gavage into the crop, the accumulation of [14C]HCB in female bobwhite (Colinus virginianus) tissues occurred to the greatest extent in adipose tissue followed by skin, liver, brain, heart and kidney, whole blood, and muscle.

DEVELOPMENTAL STAGES OF THE BOB-WHITE QUAIL EMBRYO (COLINUS VIRGINIANUS)

The Biological Bulletin, 1965
Since the well-known work by Hamburger and Hamilton ( 195 1) on normal chick enlbyros appeared, a number of workers have “? staged― embryos of various species of birds. They clearly established morphological and structural characteris tics as more reliable criteria than chronological age in the staging of chick enibryos. Rempel and Eastlick ( 1957)

Thyroid hormone changes in the bobwhite (Colinus virginianus) after hatching

General and Comparative Endocrinology, 1984
Total concentrations of thyroxine (T4) and triiodothyronine (T3) in plasma, and their biological half-lives were measured in adult and immature bobwhite. Concentrations of T4 and T3 decreased approximately 75% from Days 1 to 10 after hatching. After Day 10, the concentration of T4 did not significantly change as a function of age; however, the ...

Oral Lead Bullet Fragment Exposure in Northern Bobwhite (Colinus virginianus)

Archives of Environmental Contamination and Toxicology, 2011
Lead (Pb) is a worldwide environmental contaminant known to adversely affect multiple organ systems in both mammalian and avian species. In birds, a common route of exposure is via oral ingestion of lead particles. Data are currently lacking for the retention and clearance of Pb bullet fragments in gastrointestinal (GI) tract of birds while linking ...

Synchronization of Hatching in American Bobwhite Quail (Colinus virginianus)

Nature, 1964
IT is known that chicken embryos show great variation in their rate of development. This is due to three main factors: variations in the latent period, variations in the environmental factors of incubation and the inherent variations of the embryos themselves1,2.

Effects of DDT on bobwhite quail (Colinus virginianus) adrenal gland

Bulletin of Environmental Contamination and Toxicology, 1974
A wide range of responses to sublethal levels of DDT exist, many of which are species specific and vary within each species depending upon age, sex, and physiological state. Sublethal levels of DDT do cause an increase in the adrenal cortical tissue of bobwhite quail, which may cause increased secretion of corticosteroids, and in turn affect ...
