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 ...
