Here’s a nice piece at Sexy Loops by Jo Meder re the ‘Fabulous Pheasant’
Peacock is, indeed, a remarkable tying material that comes in its natural colors but these days is also dyed. It is a wonderful material whether in its natural state or dyed. Tails, wings, abdomens, thorax and wingcases…it is a must have material.

Absolutely one of the “Magic Materials” for fly tyers and providing metalic sheen to numerous patterns well before the advent of modern synthetics. Is there a fly fisherman out there who hasn’t caught a trout on peacock feathers? The Zug Bug, The Diawl Bach, The Black and Peacock Spider , “The Alexandra” and a zillion other patterns can be found in fly boxes around the world utilizing this amazing gift from nature. Agreed a “Must Have” material.
