If you birded Ohio years (and years) ago, you may remember Laurel Van Camp.  He was a game protector in Northwest Ohio and later a wildlife naturalist at Magee Marsh Wildlife Area.  Laurel did a lot of work with banding screech-owls and actually wrote a paper, titled The Screech Owl: Its Life History and Population Ecology in Northern Ohio

Unfortunately I don't have it handy but he talked a bit about the percentage of the different color phases, not just red and gray, but also brown.  If i can remember where it is, I'll take a look.  I'm not sure whether its available on the internet.  It was an excellent paper, worth reading.  Laurel was a wealth of information.
