A fixed action pattern elicited by a sign stimulus.

Description
A fixed action pattern elicited by a sign stimulus. The sign stimulus for male sticklebacks to attack other males entering their territory is a red ventral surface. In experiments, male sticklebacks attacked all models that had a red underside, while ignoring a realistic model of a stickleback that lacked the red belly.
