8packs/set fly fishing professional waterproof Cul De Canard fly tying feathers butt of the duck preen glands Fly tying material

Features:The description “Cul de Canard” is attributed to 1950’s era French tier tier Henry Bresson. In English Cul de Canard translates to “butt of the duck”. This gland protrudes like a knob, from the back of the bird, slightly ahead of the tail. Waterfowl preen, recondition, and waterproof their feathers with oil secreted from their preen glands. While the natural oils in the feather assist in repelling water, it is the structure of the feather itself which gives it buoyancy. The fibers on the feathers trap air bubbles and the bubbles remain trapped within the fibers, even after they are submerged.
