I spoke nothing of Geese. I only mentioned Goose. Even though, after many childhood battles with them while fishing I have come to the conclusion their only real power is the power of fear. I'm pretty sure nature's testosterone levels rank something like this.
1. Male Goose
2. Female Goose
3. Bull Shark
Bread amplifies #1 and #2. If the goose bite had any sort of power or sharp teeth humans would fail to exist and Stephen King's book on birds would be classified as non-fiction.
