Questions
When а mоther herring gull returns tо its nest, its chicks (yоung offspring) will peck аt its beаk. Scientists believed that this pecking behavior is a fixed action pattern. In an experiment to determine the sign stimulus of this behavior, scientists made cardboard cutouts of gull heads with different appearances, presented them to the chicks, and recorded the number of times that the chicks pecked at the cutout. The following graph shows the results of this experiment. The gull head on the far left was the control (or, what an actual gull head looks like). Values on this graph represent the percentage of time that gull chicks pecked at each cutout relative to the control. Based on the results of this experiment, what is the most likely sign stimulus for this behavior?
