Most goose body language is in their neck and head.
Head and neck extended upward at an angle: Curiosity, wariness (about the same thing in a goose
), a wary kind of greeting. "Who are you and what do you want?" Often they'll come running toward you when they are doing this. Inexperienced (or previously bitten) people mistake this for aggression, but it is not.
Head and neck down below body level, kind of snakey-like: "Back off, I mean business!" This is aggression.
Head and neck straight up in the air and honking loudly: "I WON!!! I am the conquerer!!" (done by ganders mostly, mine does this when he "vanquishes" the dog
). This is often accompanied by full wing extension that gives the impression of great self satisfaction.
Both sexes will fluff their feathers and wings "at you", meaning "Me very, very big goose." They do this when they want you to back off.
Of course, the fully extended tongue hissing: nothing more need be said.
