Hi everybody... I'm trying to tie a Wet/Dry fly; it calls for "covert feather" taken from the top of a duck or coot wing. I normally get all of my materials from Marriott's FlyFishing Shop in Fullerton, CA by mail, but they have about a dozen different types of duck feathers and I'm at a loss as to which feather to purchase.
My question is: which feather and what exactly does the "covert feather" look like on the duck feather? (an image would really, really be appreciated)
Thanks...
