I frequently get questions about CDC or Cul de Canard, a special feather found on ducks that makes very effective dry flies, emergers, and nymphs. What is it? Where does it come from? Why is it so special? What kinds of CDC are there, and how do you use it? And when fishing these flies, how do you treat them. My friend (and friendly nemisis from our monthly fly-tyig tie-offs) Tim Flagler [46:41] and I tell everything we know about CDC and its uses. I hope this answers many of your questions.
