I did not read all the posts so apologize if this is repeated or off beat. For those wanting to mount a bird and know the feather length, I have measured hundreds over the years before I pulled them as that was how we chased birds in WI back when wild birds were more abundant. PUSH a yard stick as far as you can up the back side of the tail, and most will be 1/16 inches longer, 1/8 max when pulled out. I miss having all the small farms to hunt and chasing individual birds with nice tails that you new were there. Either way, mounted or not, remembering the scene and the dog that got it for us makes for fond memories. Sorry if off topic.
