Why shouldn't feathers be waterproof?
Question: The cons to using feather fletchings are durability, noise (which I don't buy into the 'in-flight' noise being an issue. Handleing noise may be different, I'll grant that) and moisture. Ummm......there are several birds who have no worries about water. Why can't we use the wing feathers from these species? Are only the body feathers kept oiled up? Seems to me like the waterfowl hunters would have thought of this a long time ago.
Just curious. There must be an answer. (Likely its very simple.)
