Fly tyers in this country seem to shy away from the pheasant. One exception was Jack Gartside. That man loved the pheasant and many of his patterns featured feathers from the rooster. The Japanese are fanciers of the pheasant. You can find examples of their Kebari flies that feature pheasant. The old North Country spider patterns do not show a preference for pheasant, but many other types of game birds take top billing.
Some feathers from a hen pheasant. Many shades of color, some mottled with soft shades of brown. Some are quite dark, and the pheasant feather is almost perfect in shape. I can see in the feathers above a very close resemblance to grouse, woodcock, quail. So right there you have a savings. No need to buy three birds when you can do it with one. The hen pheasant is also a great value...a quality skin is about twenty dollars.
By changing the silk color thread and using different shades of colored feathers you can create many insect imitations. Red/Pheasant
Purple/Pheasant
Olive/Pheasant...one of my favorites.
Spiders all together....
