The relation between food deprivation and schedule‐induced attack was investigated in four White Carneaux pigeons. Attack toward a mirror target was induced by a schedule of reinforcement in which 3‐sec food presentations occurred at alternate intervals of 15 and 120 sec (multiple fixed‐time 15‐sec fixed‐time 120‐sec schedule). A continuous tone was presented during the 15‐sec periods; it was absent during the 120‐sec periods. Each pigeon was tested at 65, 80, and 95% of its free‐feeding weight in ascending, descending, and ascending orders, respectively. Two relations were apparent; an inverse relation between body weight and rate of attack, and a tendency for rate of attack to increase during the experiment. Reduction or elimination of attack when the mirror was covered with brown paper for some sessions indicated that the results were due neither to changes in activity that might covary with weight nor to habituation to the experimental situation.
