Q is for .................... Quill

What a pretty little Feather I found, grown on a Quill ready to be used as a Pen.
The strongest quills come from the primary flight feathers discarded by birds during their annual moult.
I don't think this is a Flight feather, but who knows?
Quills are denominated from the order in which they are fixed in the wing, the first called the pinion is that favoured by the expert calligrapher.
