I guess I should explain for the non-fly tier/fisher: A few years ago the hackle industry was overwhelmed with the then fashionable style of long cock feathers blended in with the hair. Less worthy feathers were used for earrings too. The trend passed and the feathers again became a bit more plentiful in fly shops for tiers. In looking at this above image, I believe the look is actual feathers, but rather the hair colored into a grizzly pattern. I do hope so…..
