Feather from what?

[piscatus absentis]

A couple of years ago I was given some nicely marked, reddish feathers and thought today they would make something like a Cinnamon and Gold. 

I've put a sample of the feather through the eye of the flee.  Any ideas what it comes from?

Possibly Summer Duck.

Alternatively could be dyed silver mallard

I would agree with Sandy. Looks like Summer duck

The terms woodduck, summer duck, and mandarin duck are oftentimes used interchangeably in fly tying texts, most often in the context of the buff colored barred flank feathers. Summer duck is a nickname that has been used for both the mandarin duck and the woodduck, there are in fact two distinct birds behind all these feathers. The woodduck, Aix sponsa, is native to North America while the mandarin duck, Aix galericulata, is native to Asia. The two are closely related biologically, the hens being almost indistinguishable in appearance, but the drakes are quite distinct on the water. However, it is the flank feathers of the drakes that are of great interest to fly tyers. They are so nearly identical that one can easily be used as a substitute for the other in all but the most strict tying recipes.

I think the icons are great. They make unread posts really stand out on the home page. They also show we are Breast Cancer "aware"!
