The mallard primaries will make good blae winged wets or upright wings for dries like the black gnat.
Hen pheasant will do much the same - march brown patterns
Black squirrel tail I've seen in a couple of mayfly patterns and in some reservoir lure patterns - its more a salmon and sea trout tying material TBH
Guinea fowl is used on some lures and wets - Ace of spades for example. Also makes a nice tail for a black wet or dry fly.
Teal does well for wet fly wings and can also make some pretty tasty looking dabblers if tied right - Teal blue and silver, peter ross etc. also makes a nice wing in some dries if you tie in Catskill style.
GP head, tails on wet flies - teal blue and silver, blae and black etc.
Bronze mallard - dabblers, mallard and (insert trouty tasty colour)
Squirrel tail - see black squirrel tail - natural is used in the appettizer lure
French partridge - french partridge mayfly.
I'm tired so that probably won't make any sense
