Animal trivia: Do you know the egg effect?

A goose that is hatching an egg, if it accidentally causes the egg to roll out of the nest because of movements such as entering and leaving the nest, it will stretch the neck and use the chin to hook the egg, then bend the neck and roll it back under the body. . We usually think that this is a reaction that is clear and controlled by itself. However, the scientist who had a good thing mischievously took the egg that was rolled out. After that, he was surprised to find that the geese did not stop, but the whole set of movements was completed, even if the egg no longer existed.

That is to say, once the specific set of actions of the goose is triggered, it will be completely reflective and will not change due to changes in environmental factors. This highly congenital innate instinct is called the “fixed action mode”, and there is a “hard-joined” neural loop in the goose’s brain that is responsible for the completion of this action.
