(I wonder, did they not hunt ducks in England?)

Or is it that the collective we call ducks, they had names for-- I know the names of some game birds-- but many birds where eaten--

perhaps hunters went hunting for canvas backs, or mallards, or eiders or (okay, i reached my limit on duck names-) but what about other water fowl-- in England swans are protected game, but what about pelicans--(who's beaks can hold more than their bellys can?) or cormorants?

I don't know enough about varieties of water fowl, or hunting to know hunters if one went out for mallards-- and what other birds where hunted. -- or where they domesticated fairly early one--like geese?
