Miller, back in the 60's-early 70's I tied and used the Yellow Hammer fly (Northern Flicker) on streams in the Tellico area near the TN/NC borders tied from road kills. I later learned that it was illegal to possess the feathers road kill or not. The Federal Migratory Bird Treaty Act of 1918 and amendments protects over 800 species of birds. The Act was in response to the slaughter to the verge of extinction of non-game species for use in the millinery trade. I also heard where wardens in the area made cases against anglers in possession of the flies using the feathers. There are exceptions to the possession rule regarding game birds killed by hunters and other species of birds collected with special licenses. Gil
