Pinch the barb on a size 8 6XL streamer hook, start black thread mid-shank and wrap back to the start of the bend.
Tie in a few fibers of barred wood duck flank as a tail, about a hook-gap and a half long, and bind or trim the butts.
Take the thread forward to the head in open wraps, tie in one strand of olive acrylic yarn at the front, then bind it back to the tail in loose open wraps and return the thread to the front.
Wrap the yarn forward, letting it lie flat rather than cording it up so it looks like a fuzzy floss, and tie it off just behind the head. Keep it loose enough to soak up water.
Tie in a small tuft of soft hair on top as the wing, reaching to about the bend of the hook or the middle of the tail; take a few wraps rearward to lay it flat, then tighter wraps forward and trim the butts.
Tie in a bunch of red schlappen barbs (or marabou) underneath as a throat, reaching back along the body.
Take the thread back a hair and tie in three strands of peacock herl on top as a topping, reaching back to about the end of the wing; trim the butts.
Build a full, shiny streamer head, whip finish, and cement.
Separate the peacock topping with a bodkin, lay the bodkin under the herl, pinch lightly with your thumb and draw back to give the topping a curved sweep over the wing.
