To analyze: The reason why egg retrieval behavior is geese is a fixed action pattern.
Introduction: A fixed action pattern is a term used to describe the fixed pattern of birds or other associated organisms. Most of the action patterns are the same for birds such as ducks, swans, and others.
Explanation of Solution
Egg retrieval behavior in geese can represent the principal habits of the geese. These actions are fixed and remain the same for all the geese. For example, if an egg of the female geese moves out of the nest, then the very first thing the female geese do is to roll back the moving egg inside the nest again, by using all their efforts and energy. The female geese will keep doing this until the egg will not be rolled back to the nest. The egg outside the egg is a stimulus that triggers the egg retrieval.
