Call Ducks: What are Call Ducks?

Many people have said to me my ducks look like the wild duck or like Mallards, so i thought i would put a describtion a some picture up so everyone knows the difference.

As far as i understand...
Call ducks, as a breed, are still being developed, they will sometime breed ducklings that can not be sold as Call ducks. Only those that are somewhere near the standard, for Call duck, should be called so. Other ducks that are too big, and have long necks, bodies and look more like a Mallard, should be sold as Pets or Australian Bantam Ducks.

Austalian CAll Ducks are not related to English Call Ducks, there was some English Calls in Australia, people have told me there was some in australia, but no one knows where they got to. Since ducks can not be imported, the breed is being developed, slowing, instead.
