DD--I don't think that the English used pheasant feathers on the arrows for their longbows. Every thing I have read is that the preferred feather for fletching was from the wing of a grey goose. More specifically, from the right wing of said goose, as the natural curvature of the right wing feather insured that the quill of the feather did not dig into the knuckle of the archer's bow hand, as the longbow did not have an arrow rest and is shot off he fist. That, and English farmers raised lots of geese. Pheasants, not so much.
