A comparison of schedule-induced attack in White King and White Carneaux pigeons

Abstract

The following conditions were presented to 12 White King and 12 White Carneaux pigeons: a fixed-time (FT) 90-sec food schedule, no food, and a return to the FT schedule. Schedule-induced attack against a pictorial target was sustained throughout the experiment for 10 White Kings and 4 White Carneaux. These results are consistent with other studies using either White Kings or White Carneaux with a pictorial target and strongly support the conclusion that White King is the more aggressive strain.
