Peacock

Fly tying peacock has a natural deep iridescent green coloration that is an excellent additive to most patterns. You can find it on all kinds of traditional flies, it’s just a very "fishy" material that works great. Hareline Peacock Eyed Sticks, Peacock Sword, Strung Peacock Herl, Blue Peacock Feather, and Peacock Herl Brush work great for adding flash to any fly pattern.
