Also . . . be sure you do not use lead-tipped arrows but only non-toxic metal tipped arrows so you don't run a-fowl of the federal toxic shot ban!!!

Just kidding. Be sure you shoot those ducks while they are flying -- no the wing as we say -- otherwise it isn't sporting! That will be a tough shot with a bow and arrow!!! Also, I'm kind of joking here.

Why not buy a shotgun and take up duck hunting the usual way?
