What is goose messages?

As an AI language model, I do not have the capability to understand the context of "goose messages". However, assuming you are referring to communication between geese, geese use a variety of vocalizations to communicate with each other. For example, they honk to alert each other of danger or to communicate their location during migration. Additionally, geese use body language such as head bobs and wing flaps to express aggression or submission during social interactions. These communication methods help geese to navigate their environment and social hierarchy.
