Abstract
A modification of the standard pigeon magazine is described. A transparent shutter, which can be displaced by the action of a solenoid and silent clutch, covers the aperture through which access to grain can be provided. This device permits the presentation of all the visual and auditory stimuli which accompany food presentation while preventing access to food at all times except when food reinforcement is programmed.
