There's probably not a bird that flies that has more uses for the fly tyer than the ringneck pheasant. From the top of its head to the tip of its tail, there's hardly a feather on a pheasant that can't be used to some good purpose. Whether it's hackle you need or tailing fibers, winging material or body material, shoulders or cheeks--whatever--it's all there

Tail Feathers:
The tail feathers on a cock pheasant are long, thick-barbed, and barred with brown, olive and black tones. The barbs of these feathers are used largely as tailing material for nymphs and wet flies, sometimes for legs and also for bodies on small nymphs. Perhaps the most well-known fly using pheasant tail feathers is Frank Sawyer's Pheasant Tail Nymph, in which the whole nymph is constructed from wound-on pheasant tail barbs overlaid with a ribbing of gold wire.
