This fly is I guess mostly off topic. But I stumbled upon it earlier today. And it is another example of using a materials, peacock & exotic bird feathers, not easily obtained. Interesting looking fly.
It uses Jungle Cock feather, over a peacock eye body, with grizzly hackle.
Jungle cock [ ジャングルコック 鳥] is a bird native to India. Long used for salmon flies.
However, the capes are pretty pricey. I will probably try the same idea with some kind of feather I already have.
