The "Durham Ranger" is a quintessential classic pattern. These intricately dressed flies were used for Atlantic salmon fly fishing during the nineteenth and twentieth centuries. Fly patterns from that time used colorful feathers from large, and often exotic birds. Today, tying these flies is considered an art.
Different patterns are used for different types of fish and for fish from different locations. The "Rock Island" streamer is a modern fly designed for trout fishing in British Columbia (Designed by Monte Smith).
