Somewhat off topic, back back in the day popular flies were bucktails, muskrat nymphs, pheasant tails, and any fly with peacock herl. In a world where fly shops were practically unknown (at least to me) and I ordered my few materials by mail from Reed Tackle scraps of fur and feathers from deer, muskrats and pheasants were always available at no cost. Add squirrel tails to the list - the price of a squirrel tail was a 22 shell, or free if you felt like dealing with road kill. Oddly enough, wood ducks were pretty scarce until the 70's when everybody and their brother started putting up nesting boxes and the population rebounded. My 70's jump shooting provided wood duck skins that supplied me to about 4 years ago. The trimmings of muskrat hide I got from trappers will last me the rest of my days.
I can't jump shoot any of my old haunts because they are all developed these days and I buy wood duck skins. My muskrat better last me because I don't know any trappers today. I buy my buck tails because it is too much work to skin, cure, and dye them.
