Question

What is the different between goose and ducks?

Answer 1

Geese are a different breed of bird from ducks.  They are larger, heavier, and have longer necks.  Geese migrate.  Ducks do not.

Answer 2

Besides the obvious physical appearances?  

Dispositions can vary greatly between species; however, as a general rule geese tend to be on the less friendly end of the spectrum than ducks.

Answer 3

Generally size, although I take your point on the Pygmy Goose. Quack - Honk, and Geese have a serated beak, as you will know if you have ever been pecked by one. Geese are generally aggressive, ducks aren't. Yes Geese graze, but so do ducks. Both like worms. Geese scare dogs, ducks don't. My postman won't get out of his van if the gander is about, however he doesn't worry if it is just the ducks.

Ducks usually eat fish and insects, while geese usually eat grains and grasses. However there are always exceptions to those rules. If you collect down, goose dung has less odor than duck dung does. Geese tend to have more webbing between their toes than ducks do.

In fact, some people call geese "grey ducks". Which points out another difference - geese tend to be grey or white or grey-white with black. Ducks tend to be all sorts of interesting colors, from green to brown to spotted and so on. There are no native white ducks in North America. However, a common domestic duck is the Pekin Duck, which looks like Donald Duck of the cartoons.
