CUL DE CANARD FLY TYING FEATHERS grow around the preen gland of ducks and geese ,which secretes the oil ducks and geese use to preen and waterproof their feathers. The oil and the water-resistant properties of CDC feathers make them great for emergers, nymphs and dry flies that ride naturally in the surface film, like the CDC Blue-winged Olive Emerger in the photo. Unfortunately, once CDC is dyed the oil loses all of its desirable qualities. That's why our  premium CDC is re-treated with preen oil after dying! The Fly Fishing Place offers two types of CDC: Oiler Puffs CDC and premium Cul de Canard feathers.



CDC FLY FISHING TIP: Flies tied with Cul de Canard or CDC offer superior flotation with no synthetic floatants required. In fact, using floatant on a CDC fly will ruin its properties!
