Of all the feathers one can use to tie soft-hackles and spiders I feel that the starling is one of the top 3. The starling has a variety of feathers that range in size allowing the tyer to tie flies from #12 to size 18 and 20. And a quality I really like is the iridescent highlight of the feathers. For the most part starling is not fragile, and winds beautifully on the hook.
I don't know if you can see the beautiful highlights in these feathers, but I think fish can.
The starling feather can be used as a substitute for Jungle Cock.
A simple fly....olive thread, a touch of dubbing, and a few turns of starling hackle.
The last few outings I have observed little black winter stoneflies about. They were seen on the snow, and along the stream edges. One of these flies has been so "very" effective on the trout I pursued.
