Distribution and excretion of hexachlorobenzene in bobwhite (Colinus virginianus)
Journal of Toxicology and Environmental Health, 1983After 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, 1965Since 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)

Oral Lead Bullet Fragment Exposure in Northern Bobwhite (Colinus virginianus)
Archives of Environmental Contamination and Toxicology, 2011Lead (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 ...

Frequency discrimination in bobwhite quail (Colinus virginianus).
The Journal of auditory research, 1986Bobwhite quail (Colinus virginianus) (N:9, aged 24 mo) were trained using a positive reinforcement paradigm to respond to an assigned "standard" frequency of either 1.0 or 3.5 kc/s by pressing a response key. Each S was trained in 2 phases to respond to its assigned frequency rather than to alternately presented tones of a different frequency. In every

Audibility curve of bobwhite quail (Colinus virginianus).
The Journal of auditory research, 1986Male Bobwhite quail (Colinus virginianus) (N:5) were initially handled, then trained upon hearing a 1.5-kc/s tone of 3-sec duration to approach a feeder-loudspeaker system and peck a response key for food reinforcement. Threshold testing in subsequent sessions using a method of limits established the species' audibility curve over 11 frequencies from ...
