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

The High Frequency of Occurrence of the Vestigial Claw in Colinus virginianus virginianus
The Condor, 1968down on both our visits. Breckenridge (op. cit.), however, doubts the importance of down as insulation for Wood Duck eggs during periods when the hen is absent. Fourth, Wood Ducks' ducklings leave the nest in response to auditory cues learned during the brooding period immediately after hatching (Gottlieb, J. Comp. Phys. Psych. 56:86-91, 1963). Similar

Temperature regulation in adult quail (Colinus virginianus) during acute thermal stress
Comparative Biochemistry and Physiology Part A: Physiology, 19831. Evaporative heat loss, O2 consumption, CO2 production, and internal body temperature were measured in unanesthetized, unrestrained bobwhite (Colinus virginianus) at specific ambient temperatures (Ta). 2. No significant change in body temperature occurred at any Ta tested, but metabolic heat production (H) increased from 42.17 W/m2 at Ta 35 degrees C

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 ...

Health Status of Northern Bobwhite Quail (Colinus virginianus) in Eastern Kansas
Avian Diseases, 2000The health status of wild northern bobwhite quail (Colinus virginianus) from Lyon County, Kansas, was evaluated by conducting comprehensive health assessments on 25 birds. Gross lesions indicative of avian pox, ulcerative enteritis, and quail bronchitis were not present.
