Herring gulls feed their chicks by regurgitating food for the chick in the nest. When a chick pecks at the red spot on the gull's beak, the parent regurgitates the food. Interestingly, the chicks will peck at any red spot, whether it is attached to a gull or not. Which features of this behavior are correctly labeled? (Check three.)
_____ Fixed action pattern -- finding a healthy variety of food for the chick _____ Fixed action pattern -- pecking at the spot _____ Innate releasing mechanism -- neural circuit that induces pecking in response to a red spot _____ Innate releasing mechanism -- the red spot _____ Key stimulus -- the shape of the parent's beak _____ Key stimulus -- the regurgitated food _____ Key stimulus -- the red spot Clarify question: What is the key concept addressed by the question? What type of thinking is required? Gather Content: What do you already know about feeding behaviors? What other information is related to the question? Choose Answer: Given what you now know, what information is most likely to produce the correct answer? Reflection on Process: Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
