To me it's the influence of the duckwing pattern....
My thoughts exactly, but I personally think it could be a combo of lack of melanizers and perhaps the partridgey stuff popping up and with a lack of melanizers it would make perfect sense to me why it doesn't cover in some. I believe that the birds that do not mature out of it as geebs describes are the birds that are lacking melanizers and the birds that do mature out of it are birds that show us that they do have some melanizers. Am I silly to think this and does it even make sense? I can't seem to spit it out the way I see it in my mind.
