canard:
An unfounded or false, deliberately misleading story.

[French, duck, canard, probably from the phrase vendre un canard à
moitié, to half-sell a duck, to swindle, from Old French quanart,
duck, from caner, to cackle, of imitative origin.]

So a base canard is a duck with a deep voice?

I thought it was the part used to make soup...
