Goose is actually the term for female geese, male geese are called ganders.
A group of geese on land or in water are a gaggle, while in the air they are called a skein.
Geese eat seeds, nuts, grass, plants, and berries. They are the largest waterfowls, the other being swans.
We have two geese at the farm. Their names are Grumpy Gandalf and Emmet. They like to waddle around all day on their webbed feet and make lots of noise when greeting the kids.
