@tsarstepan,
I'd forgotten that bread is not a great idea for them - but I haven't done that in years either since I save bread scraps or crumbs to use in some of my cooking.
I have a childhood memory from our year in New York City that one time we turned off a parkway (probably Merritt Pkway) to a pond with lots of ducks, and my father leaned over to feed a duck, and the duck grabbed his cigar..
Since this was long ago, I don't remember if the the cigar was burning or not, but I'll guess that it was.
Just saw the video, liked it, plus it was closed captioned, v. helpful.
