We do not know what happens in the minds of geese. They do seem to miss their young, but that could simply be an instinct to look and care for them. There is no way to know whether they grieve in the sense we do. Probably not, as their brains are not specialized for higher levels of information processing.
Gooses, or geese, don't have ears. They have small slots that the hear out of on the side of their head. The size truly depends on the size of the goose. I know that Canadian geese have "ears" a centimeter or two in diameter.
No, they are about the same size. But brain size does not determine smarts.
