To analyze:
Why egg retrieval behavior in geese is referred to as a fixed action pattern.
Introduction:
A fixed action pattern is an example of innate behavior; once started, it runs until completion.
Explanation of Solution
A fixed action pattern is a kind of innate behavior that consists of a series of actions. Once an organism starts its fixed action pattern, it will continue until the whole sequence of actions is completed. In geese, the egg retrieval behavior is the way a mother goose rolls an egg back into the nest, under her. She will roll the egg using a side to side motion and tuck it under her; this movement is carried out till completion even if the egg is taken away in the process. This is why the egg retrieval behavior is called a fixed action pattern.
When an egg rolls out of the goose's nest, she will roll the egg using a side to side motion and tuck it under her; this movement is carried out till completion even if the egg is taken away in the process. This is why the egg retrieval behavior is called a fixed action pattern.
